SOTA Activations October 2020 to December 2020

During this quarter I activated as follows:

Black Mountain VK1/AC-042 (again) on 3rd October

9 contacts on HF, 9 on 2m and 3 on 23cm.

VK2/ST-008 (Baldy Range) 10/10

Wade vk1mic and I went first to Baldy Range, activated on HF and 2m and 23cm.

VK1/AC-008 (Mt Ginini) 11/10

Arrived at Mt Ginini to find the gate locked at the bottom of the hill. We walked up with 2m and 23cm gear only. About 500-600m uphill.

VK2/IL-003 (Mount Wanganderry) 14/10

This summit is actually off the road but is only a metre or two above the road level. Looks like I didn’t take any photos. After this I went to Mt Alexandra.

VK2/IL-005 (Mount Alexandra) 14/10

I walked very carefully up and down the access track. Some years ago I slipped when coming down the track and fractured a bone in my right wrist. No photos…

VK2/IL-001 (Mount Gibraltar) 14/10

The next morning I drove up to Mt Gibraltar and activated it before 0000 UTC, so this one is dated 14/10.

VK2/IL-002 (Wingecarribee) 15/10

This was a new summit for me. It is a bit uncertain where to find a good operating position, the summit is spread out over a large area. the actual Trig point is within metres of a house that was under construction when I visited. I worked out a reasonable position on the roadside to activate from. After finishing here I went to Knight’s Hill and tried to find a place to activate from, but found it was all inside a gate labelled Private Property, No unauthorised access etc.

VK1/AC-040 (Mt Ainslie) 15/10

On my way home from the failed Knight’s Hill activation I called in at Mt Ainslie where Andrew VK1AD was completing an activation and working Mike 2E0YYY in the UK on 40m ssb. I don’t think I had many contacts but it was an activation.

VK1/AC-037 (Mt Taylor) 18/10

9 contacts on HF and 2 on 2m fm.

VK1/AC-035 (One Tree Hill) 20/10

10 contacts on HF and 2 on 2m FM

VK2/ST-036 (Spring Hill) 14/11

18 on HF and 2 on 2m FM

VK1/AC-008 (Mt Ginini) 21/11

Returning to Ginini to make the cw contacts not made on the previous activation. 15 contacts on HF and 2 on 2m FM.

VK2/IL-007 (Knights Hill) 2/12

The access problem was solved by Compton VK2HRX and I joined him and Phil VK2JDL to activate this summit. 12 contacts on HF and 1 on 2m FM.

VK2/ST-039 (Mt Marulan) 02/12

After Knight’s Hill activation Compton and I went to Mt Marulan to activate it. 10 HF contacts and 1 on 2m FM.

VK2/SW-028 Mt Tomorrama and VK2/SW-034 Billapoola State Forest

While writing up this blog I found that although I had photos from this trip with Wade VK1MIC, I had not submitted my logs for these activations.

The blackberry infestation on Yankee Ned hill, making it very difficult to access the summit. This used to be a fire trail.
We decided to go to Mt Tumorrama as Yankee Ned was impossible. Wade is here in the comfort of the palace/shade tent.

VK2/ST-010 (Mt Foxlow) on 31/12 and 1/1/2021

I chose Mt Foxlow for my New Year’s Day activation, as it is worth 8 points so I got 16 points for this trip, getting 7 contacts on 2m FM on 31/12 and lots more on 1/1 on HF and 2m.

SOTA activations July -September 2020

During this period I activated the following SOTA summits:

  • vk1/ac-023 Mt Coree on 11th July
  • vk2/st-053 Mt Mundoonen on 26 Aug, 4th time this year
  • VK1/AC-042 Black Mt on 27 Aug
  • vk1/ac-044 Boboyan Range on 11th September
  • vk1/ac-021 Pheasant Hill on 12th September
  • vk2/st-005 Webb’s Ridge on 17th September
  • vk1/ac-023 Mt Coree on 18th September
  • vk1/ac-040 Mt Ainslie on 18th September
  • vk1/ac-042 Black Mt on 22nd September, 5th activation this year so far
  • vk2/st-042 Bowning Hill on 27th September

One of my goals this year was to earn activation points for CW mode. I was aiming to qualify for MG on CW. My operation would generally commence on CW then move to SSB once I had made at least 4 contacts on CW. This is fairly easy now as many more chasers are looking for CW contacts. On a few occasions I closed down without getting the 4 CW contacts and that meant a return visit later in the year.

Mt Coree VK1/AC-023 on 11th July 2020

This popular site is easily accessed using a 4WD vehicle and this visit was with Wade VK1MIC. it was foggy and cold, just above freezing. Rain was forecast from about 11 AM so we packed up before that time. As we put everything back into the car, the cloud lifted and we could see that there was no rain anywhere near us. A pity as we could have stayed making contacts for a while yet. On this occasion we were trying to make contacts on 6m. 20 contacts were made there and some on 2m and 23cm. No CW contacts at all as we packed up expecting wet weather to arrive. A return visit was planned. No photos taken.

Mt Mundoonen VK2/ST-053 26th August 2020

As this is the nearest summit to where I live, I tend to activate it several times a year. 80m – 1 contact, 40m – 12 contacts, 20m – 1 contact, 2m fm – 3 contacts. No new photos.

Black Mt VK1/AC-042 27th August 2020

Contacts made on 23cm fm and 80m ssb with vk2 and vk3. None on 40m. No new photos.

VK1/AC-044 Boboyan Range and VK1/AC-021 Pheasant on 12th September

Contacts were made on 80m, 40m, 20m and 2m, with a mix of CW and SSB. The first contacts on Boboyan range were made just before 0000 UTC so the activation date in the sota database is 11th Sept.

VK2/ST-005 Webb’s Ridge on 17th September

This was a joint activation with Andrew VK1AD. He operated on 144 and 1296 and I operated on HF ssb and cw. As the first contacts were made before 0000 UTC the local date for these contacts was 18th Sept. After finishing here with light rain starting to fall, we drove to Mt Coree, the next activation.

VK1/AC-023 Mt Coree on 18th September

This activation was made directly after the Webb’s ridge activation earlier in the day. No new photos taken. I completed the 4 contacts needed to get this summit into my activation log for CW. Also made some contacts on 144 and 1296 using Andrew’s gear.

VK1/AC-040 Mt Ainslie on 18th September

15 contacts made on HF ssb/cw and 2m FM.

VK1/AC-042 Black Mt on 22nd September, 5th activation this year so far

11 contacts made on HF and 2m fm. Activated from a site fairly close to the comms tower.

VK2/ST-042 Bowning Hill on 27th September

This activation was the second I’d made this year. It was the occasion of a charity walk up the hill, where the owners of the property made it available for people to climb the hill and enjoy the view, while making a donation to a local charity which supports people requiring long term health care due to illness other than cancers. I thought this was a good cause and it allowed me to activate it again and hand out the summit points.

A number of local service organisations were present, including the Rural Fire Service. There was a coffee vendor offering espresso coffee, which I was happy to find! I think there would have been hundreds of climbers supporting the event during the day.

Qualifying a summit – making 4 interstate contacts – using the 500 milliwatt Pixie morse transceiver hi hi

I built up the Pixie kit, having bought it a year ago or more, just to see how it worked and intended to try it out on a SOTA activation.

Being invited to accompany Andrew VK1AD to Mt Marulan for a return visit, having done the same in December 2018, I decided to take the Pixie along to see if it could make even one contact with 40m conditions as dicey as they are at present.

I set up the station to use the Pixie, with the ZS6BKW doublet fed through an Elecraft T1 tuner and the choke balun recently built. (Did I write about that? Maybe not.)

I listened for a minute or two on the Pixie’s 7023 khz and could hear VK2ARZ calling CQ with a very high offset frequency, my guess was that he was on 7025 so would not hear me operating on 7023. The Pixie’s receiver is a direct conversion receiver without any inherent selectivity so if my ears had 10 khz frequency response I would have heard stations out to that offset in both directions, ie. higher and lower in actual frequency, eg. A signal on 7013 would produce a 10 khz frequency difference so the 10 khz would be coming through the receiver, as would a 7033 khz signal also produce a 10 khz audio frequency. My 69 year old ears don’t have that bandwidth any more, they have an inbuilt low pass filter.¬† ūüôā

So I spotted myself on Sotawatch using the vk port-a-log software on the android tablet, called CQ using the little blue hand key, listened, then called again. A big signal loomed in the earbuds and it sounded like a bug being used. Was it Steve VK7CW, yes, it certainly was, after the call letters marched across my ears and I logged the contact using the tablet. What strength was he? I didn’t know, sounded pretty good so I gave him 579. Received 559 in reply, not bad for half a watt. Steve said he was running an FT817 at 5 watts out. Monster power.

Three more contacts, regulars John VK4TJ in Toowoomba, Peter VK3PF in Churchill Victoria, and finally Paul VK3HN from Melbourne made it into the Pixie log and I’d qualified the summit in 11 minutes using a Pixie half watt, two transistor + one IC transceiver, that had cost me $9 for the kit.

In between the contacts I could hear some weak signals and I wondered how strong they were, perhaps they were others who I wasn’t hearing well enough to copy. So after completing the 4th contact and calling another CQ just to be sure I had worked all who were there, I transferred the antenna to the KX3 and had a better listen to the weak signals. They were weak on that radio too, and I think they were dx stations, probably US operators in a contest of some kind.

The rest of the activation was fairly straightforward using the KX3 and the same doublet antenna, some contacts on 80m, most on 40m, the Shires contest was running so I had to look up my shire, I quoted GM2 (Goulburn Mulwaree) so I hoped that was correct.

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

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.

Combining “QRP Hours” contest with WWFF activation at Mundoonen Nature Reserve

After a failed activation of this reserve a few weeks earlier I wanted to get some contacts for this reserve into the log. ¬†The QRP Club’s QRP Hours contest on 22nd October 2017 seemed like a nice opportunity.

I set out from Yass about 45 minutes before the contest start as I had a good idea of where I would operate.  On site I found I had to be satisfied with a sloping site and I put up the usual linked dipole with all links connected, giving 40m operation.  I decided to use the MTR3B CW transceiver for the CW section of the event and use the FT817 for the SSB section.

The MTR3B transceiver’s principal characteristic is its compact size and low power usage in particular on receive mode where it is about 40 milliamps, about 1/10th of the FT817.

Radio, battery, logging tablet and paddle
The MTR3B (blue), its battery (yellow), the log (red cased Lenovo tablet) and the paddle (American Morse DCP, on leg) as used in the CW section of the event

 

However the inability to conveniently and rapidly browse across the band looking for other stations calling CQ is a limitation for contesting I had not really considered before.  Nevertheless I persisted with it to try and find a way to use it best.  I had not yet used the Direct Frequency Entry function and I really needed that, so I could jump back to a starting frequency.  Also I had not recorded anything in any of the text memories.  So during the contest I opened the LNR website and read the instructions for storing text into one of the memories.  The obvious thing to have recorded for quick playback is the CQ call.  So at least I achieved that during this event!

During the CW section I made 5 contacts but of those only one was within VK2 and that was with Mike VK2IG, who with partner Helen VK2FENG was portable in another WWFF nature reserve, not far away from me, but far enough to sound distant. ¬†No AGC or even AF gain control on the MTR3 – I have a volume control in the ear buds lead. Other contacts were with VK3, 4 and 5. ¬† There was no “normal” NVIS propagation. ¬†Very pleased to have worked Warren VK3BYD/5 somewhere in the middle of South Australia, and Grant VK4JAZ who was operating from home in Brisbane. ¬†QRP is a combination of frustration and achievements.

After a half hour or so, I got a reminder that I was operating in a nature reserve, in the form of a sudden downpour of rain that became hail for about 10 minutes. ¬†Fortunately I had suspected rain was imminent and had erected the “sun shelter” shortly after the start of the event. ¬†But the slope of the operating location meant icy rainwater was running downhill and under my seat, a small foam sleeve sold for protecting computer tablets and small laptops. ¬†Before long the whole site was wet and cold and my clothing was drenched from the waist down.

The SSB section commenced at 0600 UTC (5pm local) and after working Helen VK2FENG nearby, Laurie VK5LJ and a few more, I ran out of potential contacts.

At that point, a lull in the rain seemed to have arrived so I decided packing up and leaving would be prudent.

Half an hour later I was enjoying a very welcome warm shower at home.

Fortunately my log is not important for the QRP Hours contest other than a check log, as I am the contest manager. ¬†I’m glad I was able to add a contact to a few other logs and in the process I did activate the WWFF park, though with insufficient contacts to qualify for any activation points.¬† That’s ok, this park is near to my home and I will return, hopefully in dry weather.

VHF/UHF Field day/contest Jan 14/15 2017

The VHF/UHF field day in January is one of my favourite events.  I have had some great surprises on these weekends.  I had no idea what to expect this time, though the weather was forecast as damp on Saturday and dry on Sunday.

I arrived on site around 6pm Friday night. ¬†Along the route from Yass via the Mountain Creek Road I had noticed a lot of debris on the road, including some tree branches that had been broken off by high winds. ¬†I didn’t realise a storm had gone through Canberra while I was driving to Mt Ginini, breaking trees and strewing debris all over suburban streets and bringing trees down over some of the arterial roads, leaving damage that would be visible for weeks afterwards.

This is how far I got setting up on Friday night. After this, the wind came up and the rain and sleet started.

The weather at the time was windy and when I tried to set up the tent it was clear that it would not survive that wind.  In the hope that it would clear away in a few hours, I decided to sit it out and stayed in the car.  By 9pm it was dark and I had to decide whether to  re-pack my tent and go back to Canberra for the night or hang on.  I decided to hang on.  It rained quite heavily for a while and the wind kept howling so once it was really dark, I felt there was no other option.

In the early morning it seemed to be better. ¬†The wind was still there but didn’t seem so bad. ¬†The rain had cleared. ¬†But I hadn’t slept much.

I set about the job of assembling the antennas, the tent, the interconnections and generator.  By 12 noon, the contest start time, I was just about ready to roll.

432 MHz preamp cabling

144 MHz antenna

1296 MHz antenna – end mounted

 

The erected antennas looked very much like they have for the last 10 years so I didn’t take any new photos of them. The 2m, ;70cm and 23cm yagis on one mast and the 6m 3el yagi on another, both rotated from the base using KR400 rotators. ¬†Feedlines: RG9B for 2m, CNT400 for 70cm and 23cm, RG213 or similar for 6m.

Here’s a pic of the antennas from a previous operation at Ginini. ¬†A few configuration¬†differences for the 70cm antenna but otherwise very similar this time.

VHF/UHF antennas on Mt Ginini

 

Once I got on the air, I found beacons from VK3 were very low, the Sydney beacons were almost undetectable and few portables outside the VK1 area.  Only VK2IO was heard initially, but one or two others did emerge later in the weekend.  VK1DSH, VK1RX, VK1RW, VK1MT and VK1AI were all out in the field, most of them on 50/144/432 and Dale was on 1296 as well.  We had a small number of home stations operating the bands too.

After working Gerard VK2IO (Mt Bindo near Oberon) I then worked Phil VK5AKK on both 144 and 432.  We tried 1296 too, but although I could hear a signal from his 100w, my 10w was too far down to make it a two way contact.  A digital mode would have worked.  hmm.  More power on my end would have helped too.  Double hmm.

The day progressed without any more surprising dx, and I found it hard to convince myself to stay awake after 9pm, having got very little sleep in the driver’s seat of the car on Friday night.

At 5:30 in the morning, there were good signals from the vk3 beacons, Sydney was a bit better too.  And I had a very good signal from the Mt Gambier beacon on 144.550 plus a weak signal from Mt Lofty on 144.450.  I hoped this indicated something of the contacts to be made in the following hours.

It did, partly.  VK5DK at Mt Gambier was worked, as was VK5PJ.  But conditions were not good enough to give us contacts on higher frequencies.

My surprise contact on Sunday morning was being called by Mike VK3BDL/7 at Flinders Island.  After working me on 144 and 432, Mike went on to work Chris VK2DO at Batemans Bay on 144, a contact which they were both very happy with.

Eventually the contest ended and I followed it up with a short period of activating Mt Ginini as a SOTA station, using the IC703 running from a LiFePO4 battery.  I had at 6am set up the 20m vertical in the hope of making an S2S with a US station who was looking for VK contacts.  I may have been a bit unlucky with conditions, or jut not spending enough time listening for the US signals.  No luck with S2S but did have a good contact with home station NS7P on CW.

The packing process took about 4 hours and I left the summit at 5pm.  A 2 hour trip back to Yass and a welcome shower and a cold drink when I got there.

The 6m beam seen in the foreground (in the shade, sorry) travels in a partially assembled state. The gamma match stays in place, but the extensions just come out of each element and it then is not much wider than the 2m beam and is narrow enough to be carried quite safely on the roof rack of the car.

Mostly packed up and ready to be loaded into the car and trailer. 2m and 70cm mast still to be disassembled.

 

Contacts made:  183 total.

Band totals:

  • 50 Mhz: ¬†39
  • 144: ¬† 70
  • 432: ¬†51
  • 1296: 22

Total points claimed under distance calculation rules: 55916

Points lost due to a wrong grid locator:  about 10.

Points lost due to not enough other portables:  500,000.

Mt Tantangera VK2/SM-024 activated on 10th December 2016

I was invited to join in an activation of Mt Tantangera by Andrew Moseley VK1AD, and was very pleased to be able to join him in this expedition.

Andrew collected me from my weekday accommodation in south Canberra at 7:30am on a brilliant summer’s day that Saturday morning. ¬† We decided to take both our packs to give us the option of working on several bands simultaneously.

The route taken was through Tharwa, south of Canberra, along Boboyan road until it meets the Snowy Mountains Highway between Cooma and Adaminaby, but only a few km short of Adminaby.  The trip through the mountains took us past familiar scenery, Mount Tennant just after Tharwa, the Clear Range to our east, the turnoffs for the old Orroral Valley and Honeysuckle Creek tracking stations, including various SOTA summits like Booroomba Rocks, then past Boboyan Range and Pheasant Hill.

After 2 hours we arrived at the Rocky Plains camping ground.  We prepared for the walk to Mt Tantangera, adding sunscreen, hats, packs with water and food, antenna poles and navigation details.

A track marker showing 1km to the summit – a welcome sign

Many of the horse riders camp at Rocky plains and some even set up temporary areas for their horses to roam in, with temporary electric fencing.  The initial climb up to the saddle is steady and follows a bridle trail.  Some hoof marks are apparent in the soil as you climb upwards.  The condition of the soil was damp but firm.

On arrival at the summit, a very wide flat area, we found the trig point was ideal for attaching a pole to. ¬†Initially we set up our equipment and antennas expecting we would be able to operate the two stations on different bands. ¬†However I received wideband noise whenever Andrew’s¬†FT857 was transmitting. ¬†I decided to move my equipment about 30m away, assuming it was a proximity problem and a bit of spacing would help.

That did work ok, so it was then time to get onto the bands and hand out some reports.  The bands did not appear to be in good condition.  I made relatively few contacts considering the exotic nature of the summit and its SOTA value of 10 points for anyone making a contact.   I decided to use CW mainly so as to give the CW operators a contact, and I knew we would swap bands later so Andrew would be operating on 40m ssb.

I made one contact on 20m CW, then 6 on 40m CW.  One S2S contact was also made with Ian VK1DI at Booroomba Rocks on 2m.  One of the photos taken was of a March Fly (aka Horse Fly) of which there were many.

Thanks to Andrew for offering to share this activation.  While band conditions were less than ideal, we had a great day out in the snowy mountains region and enjoyed our walking and radio operation.

Pheasant Hill, sota vk1/ac-021, south of Canberra

After activating Boboyan Range successfully the week before, I wanted to grab a few winter bonus points before they ended.  Pheasant Hill is located west of the Boboyan Road, almost at the southern border of the ACT(VK1) with NSW (VK2) in southeastern Australia.  It is in ecalytpus forest country and is 1455m above sea level.

So on this Saturday morning I drove along Boboyan road to the parking area of Brayshaw’s hut (dating back a hundred years or more) and hiked westward through the forest with the sounds of nature around me.

Finally I reached the summit area and found a suitable clearing with a handy tree stump for one of my poles.

I used one pole for the linked dipole which can be used on any of the 40, 30, 20, 17, 15, 12 or 10 metre bands.  The other pole supported the 6m vertical and a 2m dipole offset from the pole on a short length of 19mm PVC conduit.

Conditions on the bands were not bad. I made 4 contacts into New Zealand (ZL) on 20m, several “local” contacts on 2m FM back into Canberra using the dipole mounted at about 3m above ground. ¬†Only one contact on 6m, with VK1MA.

Originally in our sota summit list this one was named Pleasant hill, but that was corrected later.  As Ian VK1DI remarked after first activating this summit, it is indeed a pleasant hill.
I was tempted to stay there longer but the wind was rising and I didn’t want to be caught in rain. So after about 2 hours I packed up and headed home.

Walking distance: it took me about 45 mins to reach the summit from the car park.  The return trip was a bit faster.

Permissions: not required – it’s in the Namadgi National Park and day trips are automatically OK.

Round trip from southern Canberra – about 120 km.

VK1 SOTA party 2nd August 2015

The SOTA party on 2nd August was almost washed out, with all night rainfall and rain continuing in the morning.  By about 8am though, there was some sign of the rain easing for a while.  Some of us decided it was too risky as we are generally not prepared to operate in the rain, but others decided to activate though not on the original sites.

I changed from my planned activation of Castle Hill to Mt Stromlo.  A retreat could be made from Mt Stromlo within 15 minutes whereas at Castle hill it would take more like 30 minutes or more to reach the car, including packing time.

I originally set up on 6m and was about to set up the 10m antenna when two things happened. First I heard Dimitri VK1SV/VK2COW operating at his new home location near Gundaroo on 6m so I had to log contacts with him.  Then Mark VK1EM arrived on site, so we organised for him to make the 6m contacts that were available.

The linked dipole went up then, giving us 10m coverage.  ALthough not all originally planned activations were on the air, enough were on to keep us busy, with Mt Ainslie (AC040) operators including Marcus VK3TST and Paul VK1ATP, Adan VK1FJAW was at Black Mt (AC042) using 2m fm only (and having trouble with overload in his Baofeng), Roald VK1MTS and John VK1JP were at One Tree Hill (AC035).  Then Grant VK4JAZ arrived on Mt Ainslie and it must have been bedlam on that site.

After struggling to make his contacts on Black Mt, Adan decided to join us on Stromlo and was soon there, making his contacts on 2m and 10m.

In among this a few spots turned up on 40m so the antenna was changed over to 40m to work Tony VK3CAT, then a spot turned up on 10m showing Gerard VK2IO, so the antenna was changed back to 10m, but although I even rotated the dipole to favour that direction better, I could hear nothing of Gerard.  Should have tried CW.

Finally as lunch time approached, so did the dark clouds so we packed up quickly and were being lightly rained upon by the time we reached our cars.

In something of a compensating operation for the cancelled activation on 2nd August, VK1NAM has alerted for a 3 summit day on 9th August.  I am planning a 3 summit day too, activating two of the same summits and another different one.  Aiming for 10m/6m contacts on each, so hoping for fine enough weather to let it happen.

In addition, there will be a combined VK1/VK2 focussed SOTA QSO party on Sunday 30th August. ¬†Already, interested VK1/2/3 activators are making plans. ¬†Why not join in? ¬†VK4/5/6/7/8 activators would be welcomed with many potential contacts…

Goorooyaroo Nature Reserve, VK1/AC-036

Reviewing the track logs stored in my GPS I found the track log of my walk up to the less frequently activated summit in the eastern end of the Goorooyaroo Nature Reserve in the ACT.  It is north east of the Canberra Airport and is slightly controversial due to it including a now disused military firing range.  There are signs within it indicating unexploded ordnance, suggesting shells or even bombs may be lying dormant but still dangerous.

However the VK1 SOTA group was advised by the NSW Ranger who drives a 4WD vehicle along the service track, that as long as walkers stick to the track they will be safe.  So after a cautious start, this summit was eventually activated by several of the regular activators.

I visited it myself in January 2015 and the path is shown here.  Access is via a track (dotted in the image below) off the Sutton Rd between Queanbeyan and the Federal Highway.  Park near a gate with signage indicating no entry to unauthorised persons.

The walk to the summit took about 20-25 mins, it is a fire trail and easy to follow.  Stay on the path!

My activation of this summit was marred by very low performance of the antenna – later discovered to be due to one side of the dipole not being connected. ¬†But I got my 4 contacts…
