Mt Royal NP for Field Day and SOTA 19-20 Mar 2016

A triple-header for the weekend with the John Moyle Memorial Field Day contest, WWFF at Mt Royal National Park VKFF-0362 and SOTA from two summits within the park.

Headed first to the VK2/HU-024 summit which is just outside the southern edge of the park by a matter of metres. The activation zone to the NE is well within the park and happens to lie along Mt Royal Rd and conveniently there is a cleared space to the side of the road suitable for camping and operating from. Note that not all maps show the correct location of the park boundary or of Mt Royal Rd near the summit. SIX maps and the OzTopo GPS map V7 are OK. I activated from (-32.24473,151.28366) marked on the map with a red “X”. The park boundary and the location of the summit are also shown. There would be an elevation difference of a few metres at most between the summit and the activated location.160319VK2HU-024map

The John Moyle is a 24 hour contest starting at 0100z (noon). I arrived at about 12:45pm and walked around the area with my GPS to find the summit and check for the exact park boundary. Once confirmed I started setting up. Weather was warm with clear blue skies and no wind so a perfect day to be out and activating. A 3m metal pole at the side of the road provided a perfect mount for lashing my squid pole. I was able to raise up the base of my squid pole by 1.5m to increase the effective height of the antenna. First contact in the log was at 1:12pm, a S2S with Tony VK1VIC at Mt Ginini. Normally I use a paper log but for contests I just about always use a computer, and so it was for this contest. Well over an hour was spent working through the stations on 40m SSB and then there was a spell on CW. 40 minutes there netted 9 contacts so the pace was leisurely. I used my KX3 and had it wound up to the full 15W output. Antenna was the usual ZS6BKW inverted-Vee with the apex at nearly 10m off the ground and oriented NW-SE. To obtain this orientation, the antenna crossed the road, but with the lowest point being at about 8m it wasn’t going to be a traffic hazard!

A new three hour block had started so I could rework stations again so back to 40m SSB starting out with 3 S2S contacts. Then hunting and pecking through all the stations calling CQ for half an hour then started calling on my own frequency. The band was pretty crowded but there were still slots available. This kept me busy for another half an hour before it was time to give 20m a go. It was pretty quiet on there with only 2 stations calling from VK6. Maybe I had missed all the action. So back to 40m with the odd listen on 80m. A car full of locals stopped for a chat and find out what I was up to. The road does not go through anywhere so there was less than one car per hour going past. I mentioned my intention to scale Mt Royal and was warned about the presence of tiger snakes.

Nearing 7pm I decided to have a break from contesting and set up the tent. This was pitched next to the metal pole as the amount of free antenna feedline was limited. My operating chair was moved inside the tent and used as an operating table. After a 40 minute break I was making contacts again – still on 40m SSB. After less than 15 minutes I switched to 80m SSB where there was a lot more action. I was able to work stations in VK1, VK2, VK3 and VK4 mainly by calling CQ.

Operating from inside the tent was very nice as it kept off the cool breeze, and it really did cool down quite a lot after sunset. The evening was spent operating on 80m and 40m. There was a dearth of stations on CW, just weak rapid fire stations operating in another contest. I was surprised at the lack of activity. I was keen to make a 6m contact as there had been no response to earlier calls. I made a contact with the Blue Mountains radio club station VK2HZ on 80m and asked them to try 6m. They said their 6m operators were in bed – it was only 10:15pm. Still, they were happy to try for a contact on their wire antenna. Unfortunately it was a no-go as they were only just audible to me and I had a fraction of their transmitter power. it would have to be left until morning.

There were still plenty of stations about on 80m and a few on 40m so I kept going. Conscious of my plans for Sunday I decided to turn in at 12:45am when things became a bit quiet on the bands. It was now just CQ callers that I had worked before so a good time to cut it short. I would need all my strength and alertness for Mt Royal!

In the morning I awoke to find it already quite light. My beanie had slipped over my eyes and kept things dark and the lack of light had allowed me to sleep more than expected. It was after 7am and weather was still nice, though overcast and a little crisp. I was back on the radio at 7:45am for a short stint until 8:30am. I was able to find VK2HZ again on 80m and arrange for a 6m contact with their VHF team. This time it was successful over a distance of 183km as they were using a beam rather than a wire antenna. I also was able to just hear a station in Bathurst, but they weren’t able to hear me. The other contacts I made in the morning were on 40m and I found 80m full of ragchewers and nets.

Packing up the camp site, shack and antenna occupied an hour and then it was off to the next summit. Driving up Mt Royal road one passes through the Youngville campground area after 5km at (-32.1995,151.3094). It would make a good base if one wanted to stay a few days and operate from the park. Continuing on 3km one reaches a Y intersection with a picnic area directly ahead at (-32.1823,151.3156). At 850m elevation this is the starting point for the walk to Mt Royal VK2/HU-007. A single sheltered picnic table and a park sign marks this location.

The walk starts immediately behind the picnic table and follows the ridge line all the way to the top. There is not just one clearly defined track but a series of parallel tracks that weave in and out from each other. The gradient is steep most of the way, around 2 in 5 so it is not for the faint hearted or infirm. The elevation is 320m over 2km so its a good idea to take breaks along the way. I did not need to climb very far before entering low cloud though the visibility was still fine for following the trail. There are various rock piles along the way providing reassurance that you’re on the right track. Just after half way up there is a rocky outcrop and while it would appear attractive to skirt around it, the best way is to scramble up over it. Further up after an open area one comes to a wall of foliage with seemingly no way to get through. There is a track on the right side to duck and weave around the trees which seemed to be the best approach. I only discovered this on the way back!

The rest of the way up has quite a dense wooden canopy with some sections having very little headroom. Near the top there is a faux summit that one can skirt around to the left. One must keep going past here another few hundred metres to reach the destination. The summit holds a trig station with Royal stamped in the vane and is covered with tall spindly trees. The tracks around the trig point are quite well trodden probably due to the presence of a geocache nearby. On the trig point cairn there is a log book with a large rock sitting on it providing little in the way of disguise.

The tree cover near the trig point is quite low so rather than set up on the trig point itself, I set up my squid pole attached to a tree nearby. The antenna wire was woven around some trees and branches and with the dropoff the ends of the antenna were only about 2m off the ground. The usual ZS6BKW was used on the 8m squid pole with the antenna apex at about 7m off the deck. It had taken 1.5 hours to reach the summit and set up so there was still half an hour left until the close of the John Moyle contest at 12 noon. Again I concentrated on 40m SSB and in the time available I was able to snag 8 more contacts. At that point the computer log was closed off and I reverted to the paper log.

At contest end I was able to start spotting on SOTAwatch and the first was for 40m CW. Conditions were certainly poor as there were only 2 contacts. After 3 summit-to-summits on SSB I went to 30m CW and made 2 more contacts, one of those being a S2S with Ron VK3AFW. Then I went through 20m CW with no contacts then chased JL1NIE unsuccessfully on 15m CW. On 20m SSB I did make four contacts. There was a successful S2S with JF1NDT/1 on 12m CW then on 15m SSB one contact with a JA and nothing on 30m SSB. Finally I ended up on 40m SSB for a bunch of contacts including two CW contacts on 7090, one a S2S with Tony VK3CAT.

Once the callers ran out I stayed around for a bit on the summit before packing up and departing about 3pm. Mobile coverage on the summit was pretty good on the Telstra network though there were dropouts. For example, I missed a spot from VK2QR by 15 mins and so did not get the S2S. The signal was up to 3 bars on the phone if positioned in a certain spot, but at other times there was no data. Sitting it just off the ground the signal was coming and going.

The return journey was a lot quicker than the climb as the better tracks to take were more obvious and there was a lot less huffing and puffing. I did not need to descend very far before the cloud cleared allowing some visibility of the valleys below. It would certainly be a spectacular spot on a clear day.

Highlights

  • 2 SOTA summits and 1 park qualified
  • 242 contacts including 20 CW contacts
  • 21 park-to-park contacts
  • 15 summit-to-summit contacts
  • no tiger snakes!

Cattai NP for VKFF Activation Weekend 29-Nov-2015

The second day of the VKFF Activation Weekend I headed to Cattai National Park VKFF-0092 on the northern outskirts of the Sydney metropolitan area. The park lies on the southern bank of the Hawkesbury River in the suburb of Cattai. The park includes a popular camping area as well as outdoor facilities and a historic homestead (-33.558878, 150.892197).

151129CattaiMapMy plan was to operate in the park all day with a late morning start after a late night the evening before. This went totally to plan. I arrived at the park (-33.547513, 150.899308) off Caddie Rd via Wisemans Ferry Rd at around 10:15am, purchased an entry ticket from the machine and continued deeper into the park. After passing some shelters I entered the camping zone (-33.553787, 150.892245) for a sticky beak. There were quite a lot of campers set up there and I decided the best place for me was away from there back at the shelters several hundred metres away. None of the covered shelters were being used so I set up at the very first one (-33.558514, 150.890148) locator QF56KK nearest to the wharf. This was ideal for setting up an antenna as there are large trees on opposite sides spaced about 20m on either side. The squid pole itself was mounted against a large wooden support used for the shelter, the width of a medium size tree. The ZS6BKW antenna was used for this activation.

The KX3 was set up on a table under the shelter and I also had the FT100D as a backup but it wasn’t needed. First contact in the log was at 10:45am with Tony VK1VIC at Farrer Ridge Nature Reserve in the ACT. It seemed as though propagation on 40m would be reasonable. After this quick contact I took some time to set up the station and antenna properly for the day. Then I settled in for a session on 40m, hunting down any other park activators that came up which occupied the next half an hour. A further eight parks were worked and I was then operating on my own 40m frequency. There were plenty of chasers as far afield as VK5 and short skip was working too.

Adam VK2YK was activating Castle Hill lookout in Townsville and I was able to work him on 15m for my first SOTA contact of the day. Back to 40m and a stint on CW yielded four contacts. After that it was back to hunting for a bit and then I spotted on 15m SSB. After 15 mins making no contacts I moved on to 20m SSB for 15 mins then 20m CW for 15 mins but there were no contacts to be had. I had a break of 10 minutes for lunch until more activators started up. After an hour without a contact I stayed on 40m for an hour and there were seven more parks worked as well as two SOTA stations. The drought had broken. I self spotted on 40m SSB again and made some more contacts from that.

When things became quiet on 40m I went up to 10m and found some contest stations to work on CW. They were mostly sending lightning fast and with my 10W I was able to work Japan, Vietnam and Hong Kong. All I had to do was send my normal signal report and my CQ zone of 30. Switching to 15m I found stations operating in the same CQ World-Wide DX CW contest and was able to crack Russia, Tuvalu and Brazil as well as Japan. It was one way of racking up contacts towards my goal of 44 uniques.

After an hour in the contest there were more parks to work so it was back to 40m. Then I took a break to take photos for half an hour, visited the wharf. Upon return I self spotted on 7.144 announcing last calls and that seemed to trigger a run of hunters which kept me busy for twenty minutes. When the callers ran out I chased John VK6NU on 20m in Wandoo NP and rounded things out with a couple more parks in VK5. By then it was 5:45pm and I was mindful of the sign announcing gate closure at 6pm so it was a hurried closedown. I drove out of through the gate, parked and then walked back in. Kangaroos were clustered on the grassy areas and I also wanted to check the signage on the office building. It was unattended and indicated the park ranger is stationed at another site, probably the much larger Scheyville National Park.

Statistics

  • 63 contacts (12 CW)
  • 31 park-to-park contacts
  • 3 SOTA contacts
  • 8 DX/contest contacts
  • Bands: 40m, 20m, 15m, 10m

Oceania DX CW Contest – Brisbane Water NP 10-11 Oct 2015

BrisbaneWaterNPmapThe second weekend in a row of contesting, this time the CW section of the Oceania DX contest and a chance to activate another National Park. I headed for the Central Coast again to Brisbane Water NP VKFF-0056 just west of Woy Woy, about 60km north of Sydney. Driving south from Kariong I ended up driving through the park. Pulling off into a clearing the first potential location was checked out. It was at the top of a hill 500m off the road. After a climb and some bush bashing decided that the route was not practical. Drove back 1km along the road to a track shown on the GPS leading to the summit, but the track was fictional so this location was abandoned.

Continued further south 2km along the road to Staples Lookout. Just opposite the lookout is a gated fire trail and aerial views on internet mapping sites showed a big clearing 300m down the track. After a quick visit to the lookout, I headed down the track and discovered a very nice site for my activation. Picked a spot and then returned to the car to collect the camping and radio equipment.

Set up the double-sized ZS6BKW antenna first (the blue line in the picture above) and then the regular sized one (red line). This went pretty smoothly as there were few trees to clear with the antenna wires. The antennas were set up more or less perpendicular to one another similar to the previous week at Wyrrabalong National Park. For the station I opted just to sit outside on a chair in the evening so setting up the tent was deferred until a quiet time.

Contesting

Contesting started 15 minutes after the scheduled time of 0800z (7pm) so not much time lost and a lot earlier than the previous week. Most contacts in the first two hours were made on 40m and then 80m came into its own. Contest style was hunt and peck as I was a QRP entrant with only 5 Watts. After an hour on 80m it was back to 40m again for another hour. It wasn’t until the fifth hour before contacts were made on 160m, and these were the only three for the contest. At the end of that hour it was time to set up camp. The four-person tent was quickly erected and equipment transferred inside. There was a lot more room than the small tent used the previous week. Contesting could continue, but most of an hour was lost.

Contacts became hard to find. The local stations were all tucked up for the night. After a further hour without a contact, I did the same – after a run to the car to charge a battery. Turning in at 2am was a little later than planned and needless to say I was ready for it.

Morning

Arose around dawn, probably a little earlier than planned. Retrieved the freshly charged battery from the car and visited Staples Lookout for a better look. Captured some pictures of the sun rising and the low clouds and fog sitting over the suburbs around Woy Woy. It was quite a magic sight. See below.

Returned to the station and started contesting again. It was slow going, maybe because I was trying to have breakfast at the same time. After a few band changes ended up on 15m which proved fruitful for a couple of hours and there were useful contacts on 10m as well. Being a Sunday morning there were people shooting past on mountain bikes and the occasional bushwalkers too. At around 1pm it was clear that a storm was coming. The colour of the sky and the view on the BoM radar indicated that it was about an hour away. I started to pull down the station beginning with the 160m antenna and all the non-radio stuff inside the tent. Kept calling using the keyer in the KX3 but there were few responses other than the growing static crashes.

Operating at the indoor shack

The last contact was made at 1:50pm and then the whole lot was quickly packed up before any lightning came into view. Three trips up the track to the car and it was all over for the contest. This is quite an early close considering the contest goes until 7pm. However, I was very glad not having to pack up in the rain.

Bulgandry Aboriginal Carvings

Drove a couple of km north towards Kariong and found the Bulgandry aboriginal carvings area. This is also inside the National Park and my curiosity got the better of me and I decided to visit. With the occasional crash of thunder high overhead I proceeded along the track to the carvings. It seemed unexpectedly far from the carpark, but I was rushing in anticipation of rain. Luckily it stayed dry and I was able to admire the carvings at leisure.

Returning to the car I considered whether it would be possible to continue contesting in spite of the storm. The lack of sleep and the difficulty of re-establishing a radio site swayed me against the idea. The storm was bearing down with increasing force and within the hour heavy rain was falling. I was glad to seek shelter with a relative and sit it out.

Statistics

  • Contest contacts: 81
  • Non-contest contacts: 3 (SSB SOTA)
  • Hours contesting: 11.5
  • Hours in park: 23.5
  • Bands used: 160, 80, 40, 20, 15, 10m
  • Locator: QF56PM
  • Claimed score: 26727

Compared to the SSB contest, contacts were much harder to find and there were many stretches without a contact. I made half the contacts but operated for much less time owing to the early closedown due to the storm. It will be interesting to see the outcome of the contest.

Oceania DX Phone Contest – Wyrrabalong NP 3-4 Oct 2015

The Oceania DX Contest is an amateur radio event held annually on consecutive weekends in October. The first weekend is phone (SSB) and the second is CW (morse code). The first (and last) time I participated was in 2010 as a portable station using a kite antenna. It was a lot of fun and the video has been quite popular. This year I wanted to operate for the full length of the contest, not just for a few hours. I also wanted to operate as a portable station and this meant using low power (QRP). Luckily the contest has a QRP category so I would not need to compete with much bigger stations using beams and high power. Going portable has three advantages: (1) away from city noise; (2) have space for 160m antenna; (3) can qualify a national park for WWFF.

Location

The criteria for the location was based on: (1) must be in a national park; (2) have reasonable car access; (3) near a body of water; (4) room for antennas; (5) clear RF takeoff in all directions; (6) away from RF noise sources; (7) 24hr availability. Most of the criteria for a location can be assessed beforehand by studying internet sites. For this exercise I looked at national parks on the Central Coast of NSW and drew up a short list of possibilities within the Wyrrabalong National Park VKFF-0550. The park is coastal and divided into a large northern section and a smaller southern section. The northern section is virtually at sea level with the ocean to the east and a lake to the west. It is bisected by the Central Coast Highway running north-south. A road off the highway provides access to the park and the beach. Unfortunately the road is gated and closed at night, but I added it to my short list anyway. There did not appear to be any other accessible locations in the northern section of the park.

The southern section of the park was much more familiar as I had done the coastal walk many times. This section has ocean to the east and housing to the west and consists of a long narrow strip. The prominent features are the Crackneck Lookout providing stunning ocean views and a favourite for hang-gliders, and the Wyrrabalong TV translator tower on the southern end of the coastal walk. Of these only the Lookout is suitable. Another location was also found half way along the coastal walk next to some water tanks with access from a nearby suburban street.

Scoping It Out

On the Saturday of the contest I packed the car and set off for the northern section of the Wyrrabalong National Park at about 3pm. The goal was to reach the location by 5pm and set up in time to start contesting at 6pm. Most of the drive was along the Sydney-Newcastle freeway then head head east through Budgewoi then south through Norah Head to the park. Upon turning off the Central Coast Highway there was a large gate into the park and a sign showing the opening hours. I checked out the carpark at the end of the road and decided that it was not that suitable. Probably the best spot would be on the beach.

Left the northern section and drove through The Entrance township to Crackneck Lookout in the southern section of the park. On the approach road there was a wedding entourage and photographer actually on the road. Proceeding on and just before the lookout there was a gate – one that I had not seen before. Seems the lookout carpark now has restricted hours which seemed odd. The views from there at night are pretty nice. As a consolation, two car spaces have been provided just before the gate about 100m down the road. After a quick scout around and a gawk at the stretch limousine I decided the spot wasn’t as suitable as I was expecting.

Now down to the third option I drove back through the gate and around to the closest road to the water tanks. The road to actually get near the water tanks is gated too but intended to be used by pedestrians to access the coastal walk. The walking distance to the park is about 200m. The area around the tanks has been cleared and was within the national park according to the GPS.  I decided this would be a good spot to operate from though I was unsure how much electrical noise would emanate from near the tanks and the nearby houses. The nearest power lines were 50m away. Maidenhead locator: QF56RO.

Shack at Wyrrabalong National Park

Setup

Getting the gear to the site took three trips and then I set up the ZS6BKW antenna on the 9m squid pole with the wire oriented north-south. Next was the double-sized ZS6BKW which was awkward to set up due to the available cleared space. There was little undergrowth as the park had been burnt out recently, but there were still quite tall trees. It took some time to weave the antenna wire through and over these. I used my 10m travel mast leaving the top sections unused, and there was a pronounced bend in the mast due to the load. One antenna crossed the other one but only at about 30 degrees. They were almost parallel. A ground sheet was put down and then an operating chair which would serve as the shack for the evening. Then the KX3 and computer were installed. The chair has a small side table useful for putting things down when not seated in the chair.

Contesting

By 6:20pm I was on the air but it was getting dark so I used a headlamp to see what I was doing, especially with the computer. The bands were all very much alive. I started on 40m by hunting and pecking my way up and down the band. After half an hour there were a bunch of VKs and a couple of ZLs in the log. Then to 15m for a couple of JAs then 20m for more JAs and a US station. My 5 Watts was cutting through though not to every caller – some of them completely ignored me. Then to 160m and even though it was still early, 2 contacts were made and then to the 80m DX window for 2 more including a ZL. Back to 40m and it was definitely the busiest band and some new stations were calling. Continued to cycle through the bands calling all I could hear that i hadn’t already worked. Occasionally I would put out some CQ calls and was sometimes rewarded with a call.

After a few hours it started to cool down quite a bit and the wind was a little cool. It was time for more shelter so I started to set up the tent. I had a new “mosquito” tent so had not put it together before. The instructions consisted of a series of numbered pictures printed on a tag attached to the tent bag. By a process of trial and error the tent was set up in about 15 minutes then the radio gear was moved inside. I could continue contesting in more comfort though I was squatting instead of sitting. I managed to work Indonesia, PNG and more US stations. VK2IM who lives nearby was worked too. His signal was so strong on 20m that the KX3 automatically switched off its preamp as a protective measure. Later it was found that he was line of sight and only 6.5km away running a linear amp and a beam. It normally takes a very strong local signal for the radio to react in this way – impressive!

Some more hours of contesting and contacts had slowed down to a snail’s pace. After an hour making no contacts I decided at 1am to close down for the night. A trip to the car was made to recharge one of the 4200 mAh LiFe batteries that had been powering the computer after its own internal battery went flat after 4 or 5 hours. The radio was still running fine on its battery of the same capacity and did not need charging. Only one battery can be charged at a time. Returned to the tent for some much needed sleep.

Arose just before dawn, took some photos and retrieved the battery from the car. By 6am I was back on the radio though with the changeover to daylight savings time, this was now known as 7am. 40m was running well and I made many contacts. After 2 hours I tried 10m and 15m and made a few DX contacts with Japan, Indonesia and Russia. This was great because contacts had now been made on all the bands available in the contest. From 10:30am to 11:30am there was a spate of SOTA activations, all on 40m. Some were CW so were not logged as contest contacts and instead recorded in the regular portable logbook. At midday the KX3 was shutting down when PTT was pressed. It was time for a run to the car to charge the battery powering the radio which had dropped to 8 volts. It looked to be bulging a bit too – oops. The charger accepted the battery and started to charge it without complaining about the voltage.

Afternoon

The break gave me an excuse to have something to eat as breakfast had pretty much been skipped. Returned to the airways at 12:45pm and set up the voice keyer on the radio to put out calls while munching away. I started to call on 7.144 which is a popular frequency for World Wide Flora and Fauna activations. There were some responses but not from the usual VKFF hunters and I could not self-spot under the contest rules. 40m and to a lesser extent 20m were the bands I was able to make contacts during the afternoon. Occasionally another SOTA station would come up and I would chase them. The most notable was Takeshi JS1UEH on 15m CW.

The weather got quite hot in the afternoon and peaked at 34 degrees in the shade. I was glad to have the tent for protection from the sun. The wind kicked up too and was nearly at the point of blowing things away like the chair sitting outside the tent. During the afternoon I noticed that the UTC time and time to contest end was advanced by one hour. The clock on the computer was showing the correct daylight savings time. I decided to continue on and fix it up later. At about 5pm the long path to EU opened on 20m and many contacts were made. This dried up by 6pm and it was back to 40m. At 6pm the logger reported end of contest, but there was still an hour to go. I set the clock on the computer back by an hour and this fixed the problem. With only one hour left and darkness approaching I started to pack up and just left the voice keyer calling on 40m. The 160m antenna was pulled down first as it would not been needed at all and would take some time to roll up. Responses to calls were very infrequent by 6:30pm so the main activity was packing up the tent. QRT happened at 6:45pm, 15 minutes before the contest end and it took another 20 minutes to collect everything and transport it to the car over multiple trips. The timing worked out well with sunset at 7pm, the same as the contest end time and no need to use lights.

Log Processing

After the contest the log needed to be massaged and submitted. Entries in the log after the changeover to daylight savings had to be manually edited to take off an hour except for the last few contacts after 6pm (0700z). There was no easy way to do this other than manually. The author was contacted and could not shed any light on why the UTC time was incorrect after the switch to AEDST. Cabrillo format can be generated by the software and directly emailed to the contest manager. ADI format can be generated as well and after some editing to include National Park information, callsigns, locator, etc, the log can be imported into my station log running in Log4OM. When logging I always put in the exact frequency in the comment field. This must be extracted and put into the frequency field, and any SOTA or WWFF reference must be extracted from the comment field and new fields created for those. After importing the contest log, the non-contest QSOs can be added manually in Log4OM. Then the log is exported in ADI format for submission to WWFF to claim the national park activation. SOTA chaser contacts are also exported in CSV format and submitted to the SOTA database. There is also upload to eQSL as well, and it is all handled through Log4OM.

Highlights

At the end of the contest I had logged 165 stations plus another 15 non-contest stations (5 CW). I had worked 3 other national parks and 23 SOTA stations. All this using 5W except for the JS1UEH on 15m using 10W. Contacts were made on all 6 bands from 160m to 10m. Local station VK2IM was worked on 5 bands – all but 160m.

As a QRP station I found making contacts to be a very active process of chasing up and down the bands looking for callers and also switching bands regularly. Its not enough to just call away on one frequency and continuously log contacts like the high power stations do. I found myself calling CQ only a small percentage of the time. Often a higher powered deaf station would take over the frequency so one would be forced to QSY. However, this can happen regardless of output power.

It’ll be interesting to see how my contest score compares to other QRP stations.

Thanks to all contest stations and hunters. Great to get you in the log!

Popran NP for the Remembrance Day Contest 15-16 Aug 2015

Popran National Park  VKFF-417  (-33.38463,151.188109) QF56OO

On the entry to one of the three areas of the Popran NP lies the Ironbark picnic area. With a picnic table, isolation from powerlines and a nearby parking area it provides a great location for radio activities. On this occasion it was the Remembrance Day Contest colloquially known as the “RD”, the biggest contest event on the Australian calendar. Operating in the park allowed qualification as a WWFF award as well as entry into the contest, and all stations contacted qualify as “Hunters” for the park in the WWFF scheme.

Ironbark Picnic Area, Ironbark Rd, Glenworth Valley, NSW

The park is easy enough to find as it is not far from the M1 freeway north of Sydney as the crow flies, however one must travel a circuitous route via Central Mangrove by vehicle. The road goes no more than 100m into the park where one finds the Ironbark picnic area. A major shortcut between Peats Ridge Rd and Ironbark Rd is available, but only if travelling on foot, a route known as the Pipeline Trail. There are a number of trails leading from the carpark, however a barrier prevents only pedestrians and horse riders from continuing.

Arrival

With the contest start time of 0300z (1pm) I arrived half an hour before for setup. The 9m squid pole was set up against a metal post marking the boundary of the carpark and the ZS6BKW inverted-Vee doublet raised in an east-west direction. The nearby picnic table was filled with radio gear and a netbook for logging. There was time for a bite to eat before kick-off, but not much opportunity for listening to the pre-event broadcast.

Power

For this contest I had decided to enter as a low power station transmitting at 5 Watts since the availability of juice to run the radio was limited. Batteries on hand were two Lithium Iron Phosphate units with 4200 mAh capacity and a 7200 mAh Gel cell. These would have to power the radio as well as the netbook computer for the duration of the event. Local recharging was available in the vehicle, but could only handle one battery at a time. As a backup, operations could be conducted from the vehicle as there is no restriction on WWFF activities being conducted in this way. As it turned out, the backup was not required.

Contesting

40m SSB was the focus at the start of the contest. After 20 mins a spot from Glenn VK6HAD on Isongerup Peak VK6/SW-003 came up on SOTAwatch so I switched to 20m and was able to work him, but only received a 3×1 report off the end of my east-west antenna. Glad to get him in the log. Returned to 40m SSB for the hour and then switched to CW and there were plenty of contacts to be had.

A spot came up from Takeshi JS1UEH on 15m and I could hear him very weakly. I tried to call but there was no reply even after jacking up the power to 10W. Nick VK2AOH called him too. I’d missed Takeshi’s 17m activation, but afterwards he went to 10m . I listened there but heard nothing. Propagation conditions seemed below average. Shortly afterwards a spot appeared for Compton VK2HRX at Bulgo Hill VK2/IL-017 on 40m SSB, but I was too late as he had already flown to 20m. I couldn’t hear him on that band – he was only 120km away yet too far for ground wave.

After all that SOTA chasing I settled back in for more contesting on 40m SSB and CW. Tried 20m SSB and there were a few stations there, but I was not able to work many of them. There did not seem to be anyone on 20m CW. Later on a spot came up from Mike 2E0YYY at Gun G/SP-013 on 20m and he was too weak to attempt a contact – my antenna was pointing the wrong way anyway. There were other SOTA activations that I missed completely being focused on the contest. One that wasn’t came from John VK6NU at Mt William VK6/SW-042 as the sun sank low in the sky. I worked him on 20m SSB as a SOTA contact and only found out later he was giving out RD contest numbers as well. D’oh! Only a 4×1 report but glad to have him in the paper log even when not in the computerised RD log.

Second antenna

After one more contact I decided it was time to prepare for 160m. A second squid pole was set up and the 56m long double-sized ZS6BKW hoisted aloft perpendicular to the other antenna. This antenna covers 160m-20m and was oriented north-south-ish (the light blue one in the diagram). There was a certain amount of consternation sorting out which antenna wire would be the higher one where they crossed, and also sorting out the best tie-off points for the ends. I used the travel squid pole for the second antenna and it collapsed a couple of times. The pole was flexing so much with only half the antenna load on it that the antenna kept flying off the top as well, so in the end I put gaffa tape around the top section. One end of the first antenna had to be relocated to maintain separation between the antenna wires. What should have been a quick job took about half an hour, but it was complete before dark and high enough to not be an obstruction in the carpark.

The longer antenna is a better performer on 80m and it wasn’t long before 80m became the band of choice for contacts in the contest. A couple of hours on 80m before 160m contacts were snared, the first being with Alan VK4SN the contest manager on CW. Band noise was low so that gave my low power signal a chance. I spent most of the evening on 80m and 160m jumping between SSB and CW with only occasional forays on 40m. On SSB especially I would call certain stations and they would not respond, so I learnt the calls to avoid on account of my low power. Some stations were obviously running 400W and did not necessarily have good “ears”. On 80m I mostly ran without the receive preamp as it saves a little bit of juice.

Computing

In the early evening, the internal battery for the Netbook ran low so it was recharged using the car charger connected to a 7200 mAh SLA battery. After a few hours the charging battery went flat so had to be transferred to the car for a recharge of its own. Then later on a 4200 mAh LiFe battery was used to recharge the computer. The computer was going through batteries much faster than the radio, but its screen was on most of the time albeit at a very low brightness setting. Windows 10 had been installed a few days beforehand and there were no stability issues arising. The logging software used was VK Contest Log (VKCL) v3.12a. As I log each contact, I put the frequency in kHz in the comment field and then a name, lighthouse number, SOTA summit code or National Park code. It is useful to have the frequency for transferring to my station log, and during the contest it can be a useful reference when looking for stations that you haven’t worked. In this contest I did not use it much because there was plenty of activity right across the band. It would be good to automate the recording of the frequency, but that is beyond the capabilities of the VKCL software, and for me it is more important to have logging software that automates the contest rules.

Triple points

During the period from 1am to 6am local (1500z-2000z) any contacts made earn triple points. This provides a huge incentive for stations to keep going in the wee small hours when they should otherwise be resting. I was bitten by this bug too and kept operating until I ran out of steam at 3am. There was actually still plenty of activity and I made contacts on 160m, 80m and 40m. One golden contact with VK2GGC on 160m CW earnt 12 points. Seems the 160m CW ops are not nightowls as I expected there would have been more. Point allocation is 1 for SSB and 2 for CW, then doubled for 160m. Any 160m CW contact is prized. I did hope to work WA or New Zealand on 160m but it didn’t happen. I did make it to VK5, VK7 and northern VK4 on 5 Watts so can’t complain.

Resumption

Morning was a slow start. I must have woken before 7am and then fallen asleep again. In the end I got up around 7:45am. All the gear on the picnic table had to be restored and I was back in the contest. First in the log was Andrew VK1DA on 80m CW, also a QRP operator. There was no activity observed on 160m and very little on 80m. Everything from then on was 40m and above. There was plenty of activity on both SSB and CW with just about every slot between 7065 and 7160 kHz being utilised by contest operators and lighthouse operators for ILLW if it wasn’t being used for the Sunday morning WIA broadcast. With so much activity I found it more productive to hunt and peck for contacts on SSB rather than call on my own frequency. There were times when I’d call and call and not elicit a response, obviously due to my low power.

In the last two hours of the contest Andrew VK1NAM had activated a SOTA summit Booroomba Rocks VK1/AC-026. I chased him on 10m and 6m not expecting signals. Eventually he came onto 40m and I was able to find him after calling on various frequencies. There was less than half an hour to go and Andrew closed, but I continued on his spotted frequency. There weren’t many SOTA chasers around as I’m sure the RD Contest had forced them to go to ground. Under the RD rules you can’t use a public cluster below 50 MHz so that ruled me out from spotting my National Park activation on ParksnPeaks or on the DX Cluster. Still, I was able to catch a few regular chasers by riding the shirt tails of Andrew’s SOTA activation.

Conclusion

RD Contest scoring statistics for VK2IO

RD Contest scoring statistics for VK2IO

I closed out the contest on 40m CW having spent most of the last hour on 40m SSB. In my RD log I had 271 contacts, 96 on CW and 175 on SSB. There were 2 additional SOTA contacts on 20m SSB with VK6 so 273 total for the parks activation and 122 unique callsigns. Breakdown was 22 on 160m, 103 on 80m, 141 on 40m and 7 on 20m.

The bar graph from VKCL shows the rate at which contacts were made with red being the contact count and green being the points for each hour of the contest. Most productive time points-wise (green bar) was between 1500z and 1700z (1 to 3am) – those triple points really make a difference. Also the 160m contacts between 0900z and 1100z (7pm and 9pm) made the score kick along too.

Highest contact rate was in the first hour 0300z and the first hour after resumption 2200z. Lowest rate was in the hour when I was setting up the second antenna at 0700z. Note to self: set up all antennas before the contest starts!

Mt Olive

After all the contesting gear was packed away there was time to explore the park before my next appointment. I decided to walk up to Mt Olive which is only about 800m from the carpark. In terms of elevation it is only about 20m higher, but one must first go down hill before climbing up. The summit is a fairly flat rocky platform with loads of trees. It overlooks the Glenworth Valley to the east and one can see (but not hear) the M1 motorway in the distance. A very pretty spot for very little effort. There are other trails in the park and an attraction called the Emerald Pool, but one would require a few hours to explore them. While I was operating, a number of parties did enter or emerge from the park so there are certainly visitors, and a lot of them seemed to travel on foot to the carpark. Some may have been deterred by the access road as it helps to have some ground clearance even though the national parks say that it is suitable for 2WD.

Scheyville NP for the Trans Tasman Low Bands Challenge July 2015

Scheyville National Park VKFF-444 in NW Sydney is one of the closest parks to home. I’d been looking for a good excuse to activate this park when the Trans Tasman contest came around. This contest runs at night from 6 to midnight local time. The first challenge was identifying a suitable operating location within the park. A lot of parks are secreted behind locked gates or are not accessible once the sun goes down and so it was that part of this park is too. In order to increase the chances of success I found a number of candidate locations beforehand and printed out the map to take along.

Hunting
The map below shows the path while hunting down a suitable spot. The first location on Whitmore Rd came up with an open gate on google street view, but upon arrival the gate was locked. It provides access to an education centre and the Longneck Lagoon that I was keen to be located near. There goes that plan.
Around the other side of the lagoon off Cattai Rd (route 15) was the next option. There was a problem to actually get into the park as there was another gate, and another one further west along the road at option 3. There were also powerlines nearby too making it unattractive.
With those possibilities exhausted I cruised along the roads around and through the park looking for a suitable spot. Eventually I found an entrance to the park that wasn’t locked on Scheyville Rd. It led to a very muddy open area, and crossing this I almost got bogged. It was touch and go for a bit there whether I’d be able to drive out of it. Skirting around the edge of the area I found a track up to another open area a bit higher up. This was nowhere near as muddy and nice and flat. After a brief survey on foot, I decided this was a good place to set up.

New Antenna

For this event I built a new antenna a few days beforehand. It consists of a ZS6BKW design made with dimensions double the normal size. The resulting antenna is 56.5m long and has a 21.5m feedline of 300Ω ribbon. the theory is that doubling all the dimensions will halve the frequencies at which the antenna matches. The low bands challenge now covers 3 bands 160m, 80m and 40m with 40m only being introduced this year. This is the reason for building a new antenna. Last year I used a dual dipole (160m/80m), but being full sized it is a very long antenna and quite heavy. It was not considered prudent to add a third dipole on account of the extra weight and difficulty in setting it up.

I had time a couple of days before the contest to erect the new antenna in a local park and measure the SWR across various bands. The best matching frequencies were close to expected at 1830, 3460, and 7170 kHz. The SWR was as expected on 160m (3.6) and 40m (1.3) but on 80m was slightly higher than expected at 2.5. In any case, an antenna matcher is needed on all 3 bands so this was not going to be an issue. The arrival of a bunch of young netball players at the local park prevented any fine tuning so that will have to be held over for another day.

On site

The antenna was set up on site using a 10m fibreglass squid pole extended by a couple of 2m Aluminium mast sections strapped together. The resulting height was about 13m. There were concrete fence posts in the field so one of those was used to support the mast. The ends of the antenna were strung out in roughly a north-south direction and tied off 2m off the ground so the ends of the antenna were about 3m off the ground. The balanced feedline is best kept away from the ground so this was done by moving the car the right distance away and stretching out the feedline in the air and lashing it to a wooden fence post. An LDG matcher was placed on the back of the car and the antenna plugged in to it directly. The matcher was set up in automatic mode so that it tunes whenever there is a transmission. This is to allow for the many band changes and frequencies that would be used in each band. A small 3S 500 mAh LiPo battery provided power for the matcher. Just before the contest I spent time going to each band and tuning at various spots so that the tuner would not need to hunt when I started at a new frequency. For the most part, this worked pretty well, though at some frequencies the SWR was high enough that the tuner wanted to do a retune which takes about 3 seconds.

Contesting

At the start of the contest I started out on 40m SSB and made several contacts, then it went quiet so I went to 80m SSB. There was a lot of action on that band and signals were coming from everywhere including many ZLs. I also started receiving unsolicited reports about how loud my signal was. Clearly the antenna was working!

After a short stint on 160m SSB with only 2 contacts made I went back to 80m SSB again. The onto 40m SSB before I went to CW on 80m – and there was lots of activity there too! After 20 mins there there was still 20 mins before the end of the first 2 hour block so I went to 160m for CW and SSB contacts. Activity had picked up on 160m.

Shortly into the contest I started to use VOX on the Yaesu FT100D radio even though I was using the standard hand microphone. The button on the mic gets a real workout in a contest and I did not want to wear it out and further. The VOX was reasonably successful, though occasionally it would stick on due to RF feedback. Knocking back the VOX gain seemed to cure this problem. The long cable from the mic to the radio don’t help here. With the KX3 radio I use a PC headset and it would be good to adapt the headset for use with the Yaesu rig too.

For the remaining 4 hours of the contest, I continued in the same fashion, jumping between 160m and 80m on SSB and CW. I found that 40m was full of DX stations mainly from Japan so it was difficult to get a SSB frequency. Even on CW there seemed to be lots of stations. The “problem” was that I was out of the city in a quiet environment with a massive antenna and hearing everything. There was hardly a contester using 40m so I think everyone must have thought the same thing and given it up as a bad job. I had wondered why 40m was added to the contest. It certainly helps the VK6s get involved in the early part of the event before the lower bands open up.

Results

During the contest 178 contacts were made which was very pleasing. On 160m, 18 CW and 18 SSB. On 80m, 43 CW and 87 SSB. On 40m only 1 CW and 11 SSB. Clearly 80m was the “money” band. There didn’t seem to be any WWFF chasers amongst the contacts even though an alert had been put up for the activation on ParksnPeaks the day before. The log has been posted to the WWFF database so that the 75 different callsigns worked receive credit for working the Scheyville National Park.

The double-sized ZS6BKW is definitely a keeper. Some small variations to the length need to be tried to see if the SWR on 80m can be reduced. This may require a change to the feedline length too. The centre frequencies are all optimum for this particular feedline so whatever changes are made to the design, it will have to be scaled to ensure the centre frequency is unchanged. If you’re looking for a single antenna that will cover 160m, 80m, 40m and 20m then I’d certainly recommend this one.

The access to the operating location was very muddy. My car was covered with mud top and bottom after this activation and required thorough cleaning to remove it. The site is only for the bold 4WD owner.

The contest was a lot of fun and the time passed very quickly.
Thanks for all the calls!

Roving for Winter Field Day and SOTA – June 2015

Field Days provide a great opportunity to get out and operate portable, and combining that with SOTA is very attractive. In Winter the SOTA bonus kicks in for those >1200m peaks making it irresistible. Planned 3 summits in the first 24 hrs for this trip allowing entry as a Rover station in the VHF-UHF Field Day. Another 4 summits on my to-do list also followed.

Saturday 20 Jun

Packed the car with my regular SOTA kit but also prepared myself for the field day. Recently a 2m linear amplifier had been acquired so it needed to have a plug and also a battery to supply it. Anderson plugs were soldered on to the leads on the amp and onto a new LiFePO4 4200 mAh battery, the same type used with the KX3. The amp raises the output of the KX3 on 2m from 3W to 30W, a useful increase when contesting. The amp and a 3-element tape measure Yagi were the core additions to allow 2m operation.

The other band of interest is 70cm. The KX3 tops out at 2m so I took along my Yaesu VX-7R tri-band hand-held which would at least provide an FM capability on 70cm. An SMA-BNC adaptor was also taken along in order to connect the radio to an external antenna.

The first summit is in a forest along the road to Jenolan Caves and had eluded previous attempts to find. This time I was armed with good GPS topographic maps and knowledge on how to navigate there from SOTAwatch. It turned out quite easy to find the way to the car park and then there’s a gentle 900m walk to the summit. My backpack was quite heavy with the extra field day gear so a walk-in that was not too arduous was welcome!

There’s plenty of flat cleared area on the summit with a road track running right through. There are also posts to attach a squid pole so setting up was quick. That was lucky since the field day started at 11am and I hadn’t got there until nearly 1pm. In a variation to normal SOTA activations, a notebook PC was brought along and used for logging field day contacts so the paper log was only used for those that could not be claimed – basically anything below 6m.

I started out on 6m and made some contacts fairly quickly. Within a few minutes Andrew VK1DA came up portable on Mt Alexandra VK2/IL-005. After working on 6m I was encouraged to try 2m so the linear amp was set up and connected to the Yagi. It was a relief to find that Andrew could be heard on 2m and that the linear was working. The Yagi had to be held up manually as I had not brought along any hardware to attach it to the squid pole. I could stand up, hold the Yagi up 2.5m off the ground while making contact as I used my headset and VOX. The main difficulty was logging as my computer was sitting on the ground and there were not enough spare hands to carry out all functions simultaneously. I had to memorise the report, serial number and 6 character grid square – quite a challenge! This became easier as time went on as the same stations were being worked which had the same grid square.

After a couple of contacts on 2m it was time to try 70cm FM. My first contact with VK2TG was quite easy as he was reasonably close by in the Blue Mountains. It was much more difficult to reach Andrew being much further away. I could barely hear his signal which was also only 5W. In the end I stood up on a log to get as far off the ground as possible and used the 50cm whip on the hand-held to make the contact. It took quite a few tries but we got there in the end.

I stayed on the summit for 2 hrs which allowed a second contact with VK2TG on 6m, and then it was time to shift to the next location.

VK2/CT-002 Mt Trickett 1371m 8pts QF46xe Kananga-Boyd NP VKFF-256

Summit: (-33.833099, 149.984207) Carpark: (-33.832176, 149.9838)
A drive-in summit that I’ve activated before. Arrival was just before sunset and I decided to scout around to see if there was a trig point but nothing was found. Last year I had activated closer to the large mast and communications station just down the road. This time I wanted to stay clear of the inevitable high powered VHF/UHF transmitters on that site to reduce the noise floor. I set up on the edge of the forest near the summit in order to get away from the noisy powerline that runs down the clearing where one parks. This turned out to be far enough away to avoid the noise. The legs of the ZS6BKW antenna were woven between branches of the tall straight trees.

Making contacts on this summit was a struggle. All the Field Day participants I expected to still be around weren’t there as it was after sundown. Luckily Andrew VK1DA was still on after having moved to Mt Gibraltar VK2/IL-001. I managed to crack contacts with Andrew on 6m and 2m but 70cm proved elusive. We put it down to the heavily forested area on the summit preventing any takeoff on that band – and also the QRP and FM restriction due to my gear. See Andrew’s blog. With very little Field Day activity, I spotted on 40m CW and made a couple of contacts but it was very quiet. There was no-one on 40m SSB. Andrew helped me qualify the summit on CW as we had previously only worked on SSB. After 2 hours on the summit for only 8 contacts I pulled the plug to make the long drive to the next one.

VK2/CT-011 Mt Macquarie 1205m 8pts QF46oi

Summit: (-33.646301, 149.180801) Carpark: on summit Turnoff: (-33.649824, 149.169654)
Drove through Oberon, Bathurst and Blayney en-route to the next summit which is near the town of Carcoar. Found myself stuck on a muddy track leading to the summit with lots of logging debris under the car so decided to wait until daylight before moving the car. Overnight temps dropped below zero and in the morning the frost coating the ground and the fallen wood looked spectacular. I was able to clear the wood from under the car and reverse back down the muddy track then continue on the road I had turned off, and with the aid of the topo maps drive a few km right to the summit. Best access from the Mt Macquarie Rd turnoff coordinate is to drive nearly 3 km then at the T junction (-33.644429, 149.190715) turn left and drive 1km straight up to the summit. There are a couple of towers there and a trig point 100m behind the towers.

I set up near the approach road which was open and clear whereas the trig point has overhanging trees. First contact in the log was before 9am and I had 2 hrs before the end of the 24hr Field Day. As expected, things were pretty quiet with only 5 contacts in the log for my first hour, three of those from the same station on different bands – thanks Kim VK2ASY. I made it into the ACT on 2m (but not on 6m) so there was hope for more contacts on that band. With time up my sleeve I was able to dart off and work some SOTA stations that had been spotted. This included VK1RX and VK1NAM on 10m over a distance of 240km – pretty impressive conditions. Later on I was able to work Andrew VK1NAM on 6m as well, but that was after the end of the field day, unfortunately. i put out many more calls on 6m and 2m before 11am but no more contacts were added to the log. After the end of the field day I could concentrate on SOTA contacts so worked through my usual suite of bands and modes starting with 40m CW. Conditions were good on 40m so I was able to work into VK5 and VK7 on SSB. When I got to 20m SSB, only one more contact was made and nothing on CW. Nearing midday so I closed to get to the next summit.

VK2/CT-001 Mt Canobolas 1397m 8pts QF46lp

Summit: (-33.343101, 148.983307) Carpark: on summit
This is another summit on my to-do list. I had been to the summit before but had never done an activation. Drove via a picturesque valley and windfarm next to Mt Macquarie then through Blayney to Orange and then 20km further on is the summit. The trig point is surrounded by a carpark so I set up next to a tree slightly down the slope within 20m of the trig.

The day was still gloriously sunny but chilly at under 10 degrees. Not having to set up 2m or the netbook made for a quicker start than the 3 previous summits. First in my log were a S2S and 2 parks. Keen to get the 6m contact logged I contacted Kim VK2ASY who lives in Orange and made contact on 52.2 MHz. That was lucky as there were no other callers on 6m or 10m. Then on 20m I was able to qualify the summit on CW including one DX call from G4APO, but sigs were weak. Plenty of chasers on 40m CW and SSB to round out the activation. I closed just after 4pm allowing time to drive back to Orange in the light and tour the town. After a long walk and good feed, I set off for the next summit at 8:30pm.

VK2/CT-031 Mt Bulga 1060m 6pts QF46or

Summit: (-33.259399, 149.186005) Carpark: (-33.26211, 149.18385)
Another new summit for me and the topo maps indicated that it may be possible to drive to the summit. Tried a few different routes and found the tracks impassable and in the process circumnavigated the summit. Ended up parking on one access road and walked to the summit in the dark to check it out, most of the way bashing through the bush while watching the GPS. Having reached the top I found a road going most of the way, but it was not obvious on the GPS. Getting back to the car at night without a track was “interesting”. In all the exploration, I had found a nice camping area at (-33.26147,149.18941) so I returned there for an overnight stay.

One can walk to the summit from the camping area, but it is quicker to drive to the carpark location on the main track mentioned above and go directly from there. A track goes all the way up to the trig point so it avoids the bush-bashing. The trees are a bit dense but I was able to set up at the trig point and weave the antenna wire around the tree branches. Kicked off with 40m CW and made many contacts including VK2,3,4 and 5. I then tried 10m but there was nothing doing – the band was completely closed. Ended up on 40m SSB to make more contacts where propagation was fine. Nick VK2AOH had mentioned on SOTAwatch that he could not quite hear me so I reoriented one leg of the antenna 30° by juggling it around some trees. Started calling again and this time had a response from Nick with a 539 report. That was definitely a worthwhile adjustment as no other stations were worked on either 10m or 6m. After that success I packed up and headed to the next summit.

VK2/CT-042 Mt Meehan 1017m 6pts QF46nv

Summit: (-33.094501, 149.143097) Carpark: (-33.09438, 149.13736)
Mt Meehan is another summit north of Orange and a 3/4 hr drive from Mt Bulga. Drive to the specified location in the Mullions Range State Forest and then cross through a gate and walk 500m east up the gentle slope into the AZ. The summit itself is 50m on the other side of the fence on private property amongst the trees and there looked to be a trig point there. The fence posts can be used to support a squid pole and tie off the ends of a doublet so setup was quick.

Started operating on 40m CW with calls from VK2,3 and 5 then went to 10m CW and was rewarded by a call from Nick VK2AOH. Came back to 40m for a S2S with VK5PAS/VK5KC and VK5BJE and then back to 10m SSB but there were no calls. Switching to 20m SSB and there were weak calls from VK6. Switched to CW to complete with VK6NU and ended on 40m SSB. Received a call from VK4DD who just racked up 1000 points for Shack Sloth – congratulations, Dave!
Closed down after activating for an hour and headed for home.

VK2/CT-007 Mt Lambie 1290m 8pts QF46xm

Summit: (-33.4716, 149.9886) Carpark: on summit Turnoff (-33.454764, 149.974416)
Driving back towards Sydney provided an opportunity to activate Mt Lambie since it is just off the Great Western Hwy. The last activation here was for the John Moyle in March, and the winter bonus made it worth the effort to activate again. Besides, after a couple of hours driving, I deserved a break. Set up on the trig point as usual with the antenna oriented for EU long path.

Started out on 40m CW and qualified there quite quickly. Went to 10m but there were no contacts, and none on 6m either. I probably should have alerted on SOTAwatch for this summit. Back on 20m there were no calls from EU so I was glad of a CW call from VK6NU. Completed the activation on 40m SSB after 50 minutes and watched the spectacular sunset then packed up for the 2 hour drive home.

Thanks to all chasers and contesters for a great long weekend!
