VHF DX Summit to Summit with VK3HRA/p Allen on Mt Beckworth VK3/VC-024 QF12UQ from Mt Ginini VK1/AC-007 QF44JI – 494 km
On Sunday 3 March 2013 VK1DA Andrew and I successfully activated Mt Ginini 1760 metres ASL, on VHF DX working a mix of operators in VK2 and VK3. Contributing to the success are the commercial aircraft flying between Melbourne and Sydney at 35,000 to 40,000 feet. Aircraft enhancement (AE) mode is fast and is known to trigger pile ups. I have limited experience at AE however my observations in this blog are based on the practical application of AE. When an aircraft is in the ideal position, say mid way between two stations there is a short period where the signal peaks then fades away. To catch the AE you have to be listening for the lift in RST and quickly make contact before the signal fades. The lift can be as short as 30 seconds or it may last for 5 minutes depending on the aircraft size and flight path or alignment between the operating stations.
With the above in mind I sought interest from VK3 activators to attempt a summit to summit via AE. Allen VK3HRA volunteered and nominated Mt Beckworth 635 metres ASL. I chose to activate Mt Ginini at 1760 metres ASL.
Allen and I discussed the planning via email and decided to attempt the activation on Easter Sunday at 0800 local (2100) UTC 30 March 2013. Activation frequency will be 144.220 USB and liaison on 7.090 LSB. Equipment: Allen will be running his FT897 on internal batteries at 20 watts into an Elk 5 element log. I will be using the FT857D on external batteries at 40 watts into a 4el yagi. SOTA flag will be flying!
The weather forecast for Ginin is zero degrees with a 30 to 40 km/h wind (see picture below) it was freezing. Allen was looking forward to rain. (see link below)

After a bit of a struggle Allen and I finally nailed the S2S contact at 23:08 UTC with a 51 and 52 RST. This is the first SOTA VHF Summit to Summit (S2S) via aircraft enhancement mode in VK. see Allen’s Blog
As well as working Allen I also squeezed in a S2S with VK3WAM/p Wayne on VK1/AC-005 Mt Scabby (see Wayne’s VK1 Wilderness adventure). As soon as I finish here I’m off to Mt Coree for another activation and a S2S with Wayne on Mt Kelly VK1/AC-004. It was a great pleasure to work SOTA chasers VK3AFW Ron on AE and locals VK2UH Andrew and VK1MA Matt.
On 40m HF I worked 18 stations before UTC and 13 after. VK3MRG Marshall was portable on Mt Nelson near Hobart with a 5-6 5-7 report. Being the Easter weekend there were plenty of portable operators some did not know about SOTA in VK. I took the opportunity to inform and educate them of the pleasures of SOTA. I left out the freezing weather, don’t want to scare them off.
Thanks Allen for taking a chance, I think we have a new angle to SOTA in VK.
