More 76GHz tests

Post by g8gtz » Tue Jan 29, 2019 10:22 am

Neil, G4LDR, and I ventured out yesterday in the cold weather to see if we could extend the 76GHz record - unfortunately this is a cold weather game as the RH is generally lower on cold days.

We retested the 28km Hannington to Cheesefoot head path which went with similar results, although 144.750 was very poor!

I then went to Coombe Gibbet (IO91GI) - a 38Km line of site path with a beautiful view of the Neil's site (bottom right picture) but narrow band signals were much weaker on 76Ghz and we could not make it go on DATV.

I then moved to Coombe PMR site (also in IO91GI and a clear LoS path with metal gate in pictures) and we made it 2 way on 333ks thus setting a new world DATV DX record at 35.6 Km!

Great fun even if it was cold and there's a lot to learn about the higher microwave bands - we will return!
