SOTA – 2.4 GHz 150 km Summit to Summit

Sunday 22 April 2018 -The Peak 1230 m ASL QF43NN Snowy Mountains NSW

I have organised a S2S challenge with Al VK1RX where we will attempt a 150 km path on 23cm (1296 MHz) and 13cm (2.4 GHz) at 2.5 watts SSB.

Radio Equipment:

Video – 12 minute video starts with a couple of contacts on 2m SSB before changing to our S2S attempt on 13cm 2.4 GHz SSB.  Water condensation from the fog was a major issue.  The 13cm SG-Lab transverter is crudely protected by my ball cap!

The Peak trig station identified as Hudsons Peak trigonometric station

Apart from the great success in working Al VK1RX/2 on 13cm, my best contact on 2m SSB was Dave VK2DVM in Sydney over a 355 km path at 5 watts from the FT-817.  I happy to call that QSO as ‘VHF DX’.

11 am local time, just as the fog is starting to lift, it’s time to head back to Canberra.  Next year I will visit this summit in early summer.
