Three summits between Wee Jasper and Tumorrama on 2nd June 2019

With benign early winter weather, cool mornings but calm clear days, it was clearly the right weather for activating summits.

The first was Mt Wee Jasper. It is on a famous walking track known as the Hume and Hovell walking trail. It can be accessed from the camping area south of the Wee Jasper village, but the walk is long and recent forestry work has apparently disrupted the trail. At 7+ km it would have taken too much time out of the day too. So my access route was to first head west on the Wee Jasper-Tumut road, then southwards on the Wee Jasper forest road by a few km. Turning off onto Pheasant Creek Rd, the mountain looms into view soon and the route to the parking area is fairly obvious though the road has been cleared of any gravel and may well be soft after heavy rain.

It is a pleasant and easy walk of about 15 minutes up the forest path to the summit, where there are two concrete-and-wood benches ideal as sitting and operating radios.

I deployed the zs6bkw doublet for hf with the kx3. For 1296 the ft 817 and the transverter were connected to the 4 el yagi mounted on the camera tripod. The icom v85 was used to make some contacts into Canberra on 2m fm. No available contacts for 1296 but the Canberra beacon from Mt Ginini was very strong. On hf it was easy enough to make contacts on 40 and 80m bands using ssb and cw. I aim to “qualify” each summit on both ssb and cw. It is also satisfying to make the required 4 contacts to “qualify” on each band, though this is a personal goal rather than any external requirement.

You may have read that wombats leave a rather uniquely shaped message on the ground.  Here are a few I stepped over on my way up Mt Wee Jasper.  Each “cube” is about a cubic inch.  How they shape them like that is a matter others can deal with.

Despite the pleasant forest environment it was time to depart after an hour on summit, then pack away and head for the car. I had looked at the navigation options for reaching the next summit and concluded that the known roads were a more reliable option than trying to find shortcuts. So southwards on Wee Jasper forest road to Brindabella rd, east for a few km, then turning northeast along Nottingham Rd. About 15 km along this road is the parking point for Snowgum Mt. There is no public car access up to the summit so requires a steepish walk up a sealed road littered with leaves and twigs from the eucalyptus trees.

Setting up the gear again I heard signs that Andrew vk1ad was ready at Mt Stromlo for the planned s2s contacts including 1296 ssb. Hearing his voice weakly at first, I experimented with the position and direction of my antenna, peaking the signal in the expected direction. When his contact with a Canberra station ended, I called him and received a question as to who was calling. I moved to cw mode and sent a 20-30 second string of dots using that mode, to allow him to find the best antenna direction by setting it for the maximum signal. Dots are very good for this purpose as they have a constant average signal strength but are transmitted at maximum power, much stronger than voice signals with an average power of less than 30% of maximum. His reply came much stronger than the level I had previously heard. In fact over the next 5 minutes, signal strengths gradually increased to about 8 on the ft817 “blobometer”. (It isn’t a real meter, just blobs being lit up on the lcd display. )

Several additional contacts were then made on 2m fm, starting with Wade vk1mic, Matt VK1MA, then Dean VK1DW and I could hear Dermy VK1FDHA calling me but he was not hearing me on any of the antennas he tried. I also heard Peter vk1fphr calling but he also didn’t hear my replies.

At this point it was approaching 2pm and I knew that if I didn’t leave soon for my next summit, my departure from that summit would be in darkness. So I didn’t set up the hf antenna on this summit, failing to meet my goal of “qualifying” on several hf bands and also on cw. A return visit this year may be necessary.

I reached the next summit just on one hour after my planned activation time, sunset was at about 5 pm so I needed to get the contacts in the log. A few contacts were made with Wade and Matt over in Canberra on 2m fm but the rest of the activity was on 80m ssb and cw. I went to 40m but made only a couple of contacts on that band. Propagation conditions near sunset make distances below about 800 km quite difficult on that band. I was using my phone to log the contacts, as i could not find my logging tablet when I unpacked my gear on this summit. Had I left it in the car? Or had I packed up so quickly at Snowgum Mt that I had left the tablet there? It turned out that I hadn’t left it in the car at all, more of that to come.

I would have to go to my backup logging technology, paper and pen. That posed a small problem because although I had a notebook there was no pen in my pack or in the accessories box. Then I remembered that I had been intending to test the logging functions in the ParksnPeaks ios app on my iPhone. So, logging on this site was done using the ParksnPeaks app on the iPhone and it did it very well. The test version I had was working well.

It was then coincidental and somewhat ironic that when I went to 40m I was called by Sue vk5ayl, the developer of the ParksnPeaks app. We had a good chat and I mentioned that i was using the app for logging.

But the light was fading and I had to get out of the forest before darkness made it difficult. So I called it quits at about 5pm, packed up and found my way back to the car.

Approaching the car, I was surprised but relieved to find my logging tablet on the ground behind it. Thinking back to when I had prepared for the activation, removing the ft817, 1296 transverter and tripod from the pack, I must have dislodged the tablet and failed to put it back into the pack. Another reminder of how important it is to look around before departing.

It was now almost dark and I did not want to drive back through the Wee Jasper forest, it is the time of day when kangaroos and wallabies move around in search of food. So I drove west to Tumut, stopped at the Oriental Hotel for dinner, then drove to Gundagai and back to Yass along the Hume highway. The highway is also named after the early explorer whose name was given to the walking track mentioned earlier.

On the way I crossed this bridge with a unique name, I couldn’t resist stopping to take a photo of the bridge sign.  The bogs must shake a lot in that area.

Three summits, 18 activator points and some s2s points for the summit-to-summit contacts made. And a good meal at the Oriental.

WIA AGM weekend in Sydney 25-27 May

The Wireless Institute of Australia’s Annual General Meeting (AGM) was scheduled for the weekend of 25-27 May and I offered to give a short presentation about SOTA as one of the technical presentations on the Saturday afternoon.  ARNSW which operates from its site at Dural in north-west Sydney was also scheduling a morning of exhibitions in association with the WIA AGM events and coinciding with its monthly trash n treasure event.  So we were invited to exhibit there and explain SOTA to interested people.

The initial contact for the exhibition was Compton VK2HRX and we collaborated on the nature of the exhibit to be set up.

On my way to Sydney I called in at Mt Gibraltar, sota reference VK/IL-001 to make at least 4 contacts and qualify for the 4 points available from that summit.  I found that a short time earlier, Peter VK3PF had been at that site.  During my operation I heard Peter at good strength, activating another summit nearby, Mt Alexandra VK2/IL-005.  We made our S2S contact of course and while I would have liked to follow Peter to that summit, I wasn’t sure I had enough time (actually I would have).

I reached Parramatta in western Sydney at about 3pm and checked into my hotel, reorganised my back pack, changed my clothes and then took the train into Sydney, stopping at Town Hall station, very convenient as the evening event was located at the Town Hall in the Marconi room.   After some announcements and speeches by various officials of the Waverley Amateur Radio Club, which was celebrating its own 100th anniversary, a fascinating presentation was given about the achievements of Australia’s signals intelligence network during the 1940s.  The presenter was David Dufty, the author of The Secret Code-Breakers of Central Bureau: how Australia’s signals-intelligence network helped win the Pacific War.  His enthusiasm and knowledge of the subject and how he came to learn of the details was very interesting as it followed my visit to Bletchley Park in the UK three years ago.  So many details had been kept secret until relatively recently, it seems.

On the Saturday morning the formal AGM was run and as has been the norm recently, this went fairly quickly and was over within an hour.  In the open forum session following the formal phases, a lot of questions were asked about the outcome of the recent ACMA review of the examination and callsign allocation contract.  It seems there are still a lot of fine details yet to be clarified.

During the afternoon session of technical presentations I presented on the subject of SOTA, explaining how the award works, how summits are verified and approved and gave some statistics on the number of activators and chasers, contacts made, etc.

I ended my presentation with a short personal history of involvement in SOTA and how it relates to my health, which I am sure is much better than it would otherwise be.  I suggested that activities that involve you getting out of the shack and out into nature are not only fun from a radio perspective but are approved by our partners, so what more could you want?

At the dinner on Saturday evening the group heard a great presentation on the Apollo program and what we have gained from it, from Prof Fred Watson, Astronomer at Large for the Australian Government.  I found his presentation highly entertaining and informative, he is a very good speaker and if you ever get a chance to hear him speak I recommend it (he has a weekly spot on ABC local radio’s evening program).

On the Sunday morning we went to Dural and set up our exhibit promoting SOTA.  A number of clubs from the Sydney area also exhibited, also ALARA, the WICEN group and CREST had stands.

Here are a few photos from our stand and others:

We handed out about 30 copies of our SOTA brochure and had some good chats with various people who wanted to know more.

Overall we thought the exercise was well worth while.

After I left Dural I headed up to Mt Tomah VK2/CT-043 in the Blue Mountains.  I operated until just about sunset near 5pm local time, after which I closed down and packed up the gear in the rapidly cooling evening air.

The next morning I drove up to Mt Bindo a little earlier than planned as there was a forecast of low temperatures and a high probability of rain.

I did qualify the summit, with 5 CW contacts and 4 SSB contacts, during which my pole collapsed three times.  After the third collapse in a very strong gust of wind, I decided to pack and go, as the clouds to the west were looking dark and I wasn’t really sure of my way down the mountain.

Only a short time later, I was 20km away enjoying a hot coffee at Oberon, it started to snow and I was really glad I didn’t get caught in that on the hilltop with radio gear at risk.

On the way from Oberon southwards to Goulburn, there was quite a lot of snow on the roadside and in the countryside.  So glad I wasn’t still on a mountain in that.  A big change from the weather I had enjoyed three days earlier on the way up to Sydney.

 

 

SOTA on 23cm, 23 March 2019

In keeping with the trend for activity days that match the band with the day of the month, a 23 cm activity day in and near vk1 on the 23rd of March was organised for SOTA operators by Andrew VK1AD.

I operated from Mt Mundoonen, which is near Yass.

imgp0017

The antenna for 23cm was a 4 element yagi mounted on a camera tripod as seen in the featured photo above.

The weather conditions were misty at 8am, but it cleared up later.

The operating position for this activation was from inside a sun shelter, a small 3 sided tent structure that I find helps a lot to reduce sun and wind exposure and is also useful in rain.

The sun shelter protected the operator from sun and wind. This shows the 23cm yagi near a half wave vertical for 2m fm.

I was impressed by the signals received on the 2m dipole. The beacon from Sydney VK2RSY was good copy and I heard the VK3RGL beacon from near Geelong at a low level. Surprising to hear it on such a low gain antenna. Zero db above a dipole…

[edited following comment about reception on the 2m dipole] A note on the dipole: Testing the 2m dipole antenna for SWR while mounted at about 4m elevation, offset about 2m from my metal clad shed at home, I noted a significant change in impedance depending on whether the dipole was end on to the shed, or aligned broadside to the shed. Clearly a 2m offset from the shed is insufficient for there to be no interaction, so you wonder what is the effect on each antenna when you see antennas mounted on cars, with spacing of several inches only between antennas for various bands.

The Hotham S2S-fest February 2019

For several years a dozen or more SOTA fanatics have met at the Victorian snowfields destination of Mt Hotham for a weekend of multiple activations, many S2S contacts between summits and some social activities. I had intended to join in this event several times in the past but various problems prevented it.
This year I made it and had a great time too. The organiser of the event is Brian VK3BCM who manages the lodge during the winter and knows the area well.
Wade VK1MIC was also keen to attend so on Friday 1st Feb we travelled together down the Hume Highway from Yass to Albury then south to Mt Big Ben to score our first points for the weekend. But about 3/4 of the way up the forest road we found a substantial tree blocking the road up to the summit.

Road blockage. Decision made to go to another summit rather than spending time clearing this road.

We decided it could take a long time to clear the road and there could even be more trees blocking the road further on, so decided to turn around and go to Mt Porepunkah.  Taking the route suggested by the GPS was not successful and after consulting several blogs we found which route was recommended.  It was quite easy to reach the summit that way and we activated the summit successfully, before heading for Mt Hotham via Bright.
On Saturday we joined a convoy of three cars heading south west to Mt Murray and Mt Selwyn and others, but after Mt Selwyn we decided to detour back to Bright to refuel for the following day.  That might not have been necessary as fuel would be available in Omeo but it seemed prudent at the time.

L-R Compton VK2HRX, Wade VK1MIC, Andrew VK1DA, Ken VK3KIM at Mt Selwyn

On the Saturday evening activation at Mt Hotham, Wade wanted to activate on FT8 and did so successfully on HF, though the subsequent sked with Compton VK2HRX on 1296 mhz using FT8 was unsuccessful for reasons that are unclear. The 1296 transverter and 4 element yagi was put to good use, with a dozen or so of the activators making contacts with Andrew VK3JBL at Mt Torbreck, a distance of just over 100km and all the more satisfying as Andrew’s transverter was operating at reduced power of a few hundred milliwatts.  The photos below were provided to Gerard 2IO for his composite article on the weekend, thanks to the photographer. They show Wade and me, with the setup used on 1296 (FT817 and SG-LAB transverter, a 4 element yagi on a camera tripod weighed down (against the breeze) by a bag of groceries I found in the car… have to be creative sometimes.

On Sunday we joined a group heading east to Omeo then north for a round trip via five summits north of Omeo.
On most summits it was possible to share a single HF station to make the CW contacts I needed to qualify on CW and count towards a CW MG award. Towards the end of the Sunday trip storms were approaching and we adopted a hit and run strategy by making four quick contacts on 2m FM and not setting up on HF at all.  I’d like to return to all of those summits and have a more leisurely activation on HF bands, ssb and cw.
The visit to the historical Washington Winch site was interesting too.

Cheerful road sign

Due to the large number of activators trying to qualify their summits on 146.5fm, it was often difficult to satisfy all activators with immediate contacts.  Some methodology for making more use of the VFO dial, using another 2 or 3 frequencies would be useful. There are channels available but we need to realise that 25 khz channel spacing is not enough protection from a very local signal.
Apart from the radio contacts I also learned a thing or two about my 4WD and gained some confidence about climbing steep rocky roads.
On the Monday after helping Brian to move a woodpile inside the lodge we drove over to Wangaratta and enjoyed a coffee with Warren VK3BYD.  Then we drove up to Holbrook and visited Bernard VK2IB and his partner Deb.
It’s always good to meet people you have talked with on air.
I had met about half of the gang at Hotham before and it was great to catch up with them. And it was great to meet others who I had spoken to on the radio but was not meeting in person for the first time, in particular Sid ZS5AYC and Adele ZS5APT. Sid was working with an injured foot but managed to activate every summit visited. (I noticed that Adele was subsequently successful in gaining her Mountain Goat award, which was great to see.)

Three activations in Tasmania, November 2018

Having negotiated some SOTA time on our trip to Tasmania I thought I would be very happy to add one VK7 summit to my activation list, adding a new association in SOTA parlance to my list of associations activated.

The ideal summit in Hobart is the ever-present Mt Wellington which towers over the city and spends much of its time bathed in cloud or rain. At 1270m and only a few km from the city which is at sea level, it is a commanding presence to anyone noticing mountains as they scan the horizon, ie. any SOTA activator. In Hobart there are a number of SOTA qualified summits nearby.

On Wednesday 14th the weather forecast was for afternoon rain, but mid afternoon it seemed to be fine and I thought that could be my opportunity. So I ventured out with some cautious enthusiasm.

Arriving at the top of the mountain I could not see any details of the broadcasting towers and indeed had to look carefully to identify the trig point. There were very few people wandering around due to the threatening weather, which suited me very well.

I set up the gear and antenna using some large rocks as a protection from westerly wind and rain. The tarp I normally use to provide a clean surface to sit on was used instead to cover the radio to protect it from rain. I used an umbrella to keep most of the rain off my clothing, though I had donned the raincoat and pants. Radio conditions were not good, but I managed to make contacts on 40m and 20m using cw and ssb.

Rain on the legs and shoes

Here I am cowering under the umbrella while operating at Mt Wellington

The next day I had an opportunity to activate another summit in the Hobart area. I didn’t know how ambitious to be with only a few hours available. So I opted for a local summit Mt Rumney which is between Hobart city and the airport. There is comms gear on the summit, which was producing some spurious signals on 40 and 20m.

I found a track just off the roadside at the top, which ended with a gate, for service access to the comms compound. The roadside barrier provided a mounting point for my antenna pole.

Operating setup at Mt Rumney

On Friday 16th Nov I drove from Hobart to Devonport, but via the Ben Lomond National Park where there was a very attractive option, Legge’s Tor VK7/NE-001. This is a truly spectacular trip mainly for the passenger in the car, but the driver gets a few glimpses of the trip up the Jacob’s Ladder in the few moments he can afford to look elsewhere but the road. The pics below show some of the scenery en route to the summit in the car, and the walk on foot. On the way back down I stopped several times to grab photos of the scenery, I don’t think these shots do it justice.

On the radio, I made about 20 contacts on 40 and 20m, CW and SSB. After running out of available contacts I noticed a few spots of rain on the logging tablet, so decided to quit while I could walk down and be dry for most of the distance to the car, about 1.5km. As it happened, I had just opened the car and started making a cup of tea when the rain started to get heavy. Just lucky timing.

The small pole in the far distance made me think I had 500m to go, but in fact it was only about 200m and the pole was quite small. Heading up this way was the right way to reach the Activation Zone

This activation capped the SOTA part of the trip to Tasmania in a spectacular way.

SOTA activation at South Black Range VK2/ST-006 to complete the MG award

Leaving Canberra at 7am and heading out via Hoskinstown to the South Black Range summit, I was ready by 8:30 am to make contact with a group of SOTA enthusiasts back in Canberra.  The plan was to first use 146.5 fm to make local contacts with whoever was there.  Then go to 1296 MHz ssb to make a few contacts there, and then go to the HF bands.

Right on time, Andrew Vk1AD spotted himself on sotawatch.org showing he was set up and ready for the morning’s contacts with a group of SOTA trainees at Mt Stromlo.

Also Matt VK1MA, Al VK1RX and Ian VK1DI were on other summits.  These four operators were on air on the first day of SOTA in VK1, 1st Feb 2013 and we were all on air when each of us have qualified for the 1000 point Mountain Goat award.

We made our contacts and after the 4th contact, several goat bleats were heard on my radio.

Rock, cairn and Trig at South Black Range
The unique shape of the VK2/ST-006 hilltop. The cairn and trig are on top of a huge rock.

I then moved to 1296 and made contacts with Andrew VK1AD and Bill VK1MCW.  The contact with Bill was made on CW as a first for 1296 SOTA in vk1.

After that it was 80m and 40m.  Conditions were favouring longer distances on 40m and it was necessary to use 80m to make contacts into Sydney or into the Melbourne area or any points closer in.

After spending several hours on the summit and getting colder all the time, it being only just above freezing point, I was suddenly surprised by hearing a voice.  There was Matt VK1MA walking towards me grinning and offering me a Mountain Goat ale.  We are lucky in Australia to have a boutique brewery that has produced this very aptly named ale.

After completing the activation and packing away, Matt helped me carry all the equipment back to the car down the hill a bit, then I headed off to Mt Cowangerong to make it a double activation for the day.

Second last activation before reaching MG

My activator score after the Gippstech trip was 984 so I was then able to plan two activations of 8 point summits to reach and exceed 1000 points, the requirement for the Mountain Goat award under the SOTA programme.

Thursday 19th July brought reasonable weather and Friday was forecast with rain and snow down to 900m.  The summit I had in mind was Yankee Ned, Vk2/SW-026 at just over 1200m, but I did not plan to sit in falling snow, sleet or rain while doing it.  So Thursday it was and I set out from Yass in the morning, arriving at Wee Jasper about 50 mins later, then reaching the summit parking spot at 90 or 100 minutes.  Remarkably there was logging traffic on the Wee Jasper forest road and the dry weather allowed the truck to stir up a huge dust cloud, making it necessary to drop back and allow the dust to settle.

At Yankee Ned it was a 20 min walk up to the summit itself, where I set up my ZS6BKW doublet, the LDG tuner and the FT817.  I also had brought an amplifier and planned to try it if conditions made contacts with the 5w power level too difficult.  As it happened, after making only one contact on 80m CW and making no SSB contacts after calling for 10 minutes, I decided to connect the amplifier into the antenna circuit between the radio and the ATU.  It made quite a difference, and I was able to make a string of contacts in short time.  One contact was with Tony VK3CAT who was mobile in Melbourne and offered to stop shortly and give me a CW contact.  That was the first of several CW contacts and I was very pleased to qualify the summit on CW as well as SSB.

By then it was 15:30 and the sun was getting noticeably lower in the sky, the pine trees around the summit were sufficiently tall and thick to cast quite a cold shadow over me and my equipment.  So after making all the contacts that seemed possible I packed everything up and descended to the car with 995 points on the virtual scoreboard.  All was ready for the coming Sunday and the activation that would seal the deal for the MG award.
