One Tree Hill VK1/AC-035 876 metres ASL, QF44NU, Canberra Nature Park
“From Australia down under I continued with the EU/UK DX chase to sunset at 08:25 UTC working stations in England, Hungary, Germany, Slovenia, France, Italy, Greece, Austria, Finland, Portugal, Belgium, Spain, Sweden and general DX contacts in New Zealand, America and finally Venezuela”
The plan is to activate One Tree Hill around 07:15 UTC for SOTA DX and EU Summit to Summit (S2S) contacts. I left work at 16:30 for a 20 minute drive to the township of Hall close to the ACT northern border with NSW.
One Tree Hill is the last of 10 one point local summits to be activated in 2014. The summit walking track is a part of the Canberra Centenary trail which opened in October last year. The track starts in the township of Hall and meanders north along a public access corridor surrounded by private property. For track details see One Tree Hill post 7 November 2013. Distance to the summit is 4.2 km which should take between 50 to 60 minutes, less if you cycle. On this occasion I motored along to be on the summit inside of 50 minutes. Temperature is 26 degrees, heart is beating away and I’m dam hot. Unlike the trek in November, the number of annoying cattle dung flies is low however, the large biting March flies are back. March flies (in small numbers) attack humans, livestock and domestic pets to acquire blood. One of Australia’s nasty little critters!
Equipment for the activation: FT-857D, 20/40m link dipole, 4S 4.2 Ah LiFePO4 battery, two 7 metre squid poles, 10 metre length of coax RG58AU, mobile phone with RRT or SOTA Goat, insect repellant, food, water, head lamp and a first aid kit.
One Tree Hill Lookout platform – the summit has a very low RF noise floor, perfect for SOTA and chasing DX.
The ground in front of the lookout falls away quickly to a fence line. On my last visit I had the leg of the right or east element end tied off at a fence. Although the antenna radiated a signal long path to EU, I was not happy with the sharp angle between the elements.
Antenna – 7 November 2013
This time to raise the dipole end, I carried a second 7 metre squid pole to elevate the right side element 4 to 5 meters above the fence line.
Compare the two pictures – below is the same antenna using a squid pole to raise the end of the right element.
Fellow SOTA activator Andrew VK1DA was planning a simultaneous 2m activation of Black Mountain VK1/AC-042, but at short notice changed the activation to Mt Ainslie. View south to Canberra – a fuel reduction burn operation underway at Black Mountain.
Started the activation at 07:07 UTC on 40m, 7.122 MHz (7.090 was occupied) for local VK chasers around the south-east states of Australia. Confident I would qualify the summit on 20m, I wanted to share the single summit point with local VK SOTA chasers for 10 minutes to anyone quick off the mark. VK chasers were Mark VK1MDC, Gerard VK2IO, Bernard VK3AMB, Peter VK3PF, Peter VK3FPSR and Nev VK5WG. Thanks guys good to work you.
Started the DX session at 07:20 UTC with a spot on 14.320 MHz called CQ SOTA a couple of times, within seconds Mike G6TUH in Sussex was the first chaser with a solid S5-9 R5-6 report. Next, two Russian stations started transmitting over the top of me, commonly known as ‘crocodiles’, on the same frequency. I moved to 14.310 MHz for clear air and followed up with a new RRT spot. Next three chasers were Michael DJ5AV, George EA2LU and Colin G4UXH.
Summit to Summit contacts were Andrew VK1DA operating on 2m FM from Mt Ainsle VK1/AC-040 and at 16,385 km Herbert OE9HRV/p on an Austrian summit OE/VB-501 Hittisberg. Thanks Herbert a solid 5-8 signal to One Tree Hill.
From Australia ‘down under’ I continued with the EU/UK DX chase to sunset at 08:25 UTC working stations in England, Hungary, Germany, Slovenia, France, Italy, Greece, Austria, Finland, Portugal, Belgium, Spain, Sweden and general DX contacts in New Zealand, America and finally Venezuela.
3 U.S. stations worked were Matt K5UQ in New Orleans, Gary AB9LF in Memphis, and Bill W1OW from Massachusetts. The surprise contact for the evening was Mike YV4MT near Valencia, Venezuela, 15,300 km.
VK SOTA chasers on 20m were Greg VK8GM, Ian VK5CZ Paul VK5PAS, Steve VK4KUS, VK1MA Matt, VK6NU John and Patrick VK5MPJ. Patrick mentioned he was new to SOTA chasing, thanks Patrick hope you enjoy the growing VK SOTA activity.
This activation is the eighth in a series of SOTA DX activations involving DX summit to summit contacts between VK and EU. I trust I have consistently demonstrated this is not a fluke or Andrew being ‘lucky’, it is what its is, a well planned activity taking advantage of the grey-line propagation window between VK and Europe. In doing so I have attempted to promote mountain top activations as an alternative to noisy suburbs. We have seen a measure of good will between VK and EU SOTA activators/chasers, demonstrated through reciprocal activations from the EU and UK, which has benefited all chasers in VK. During the Australia spring, summer and autumn seasons working the last 90 minutes of daylight is a proven method of chasing summits in Europe. It’s now over to other VK SOTA activators and chasers to take up the challenge. Get out on a summit, 90 minutes before sunset and work the grey-line.
While writing this post, I had the pleasure of chasing Mike 2E0YYY on GW/NW-070 Great Orme in North Wales. Mike started his activation at 07:00 UTC, a deliberate decision to work the last hour of daylight in VK.
