8 Nov 2012 – VHF/UHF

Tim Kirby, G4VXE from PW spoke about the use and propagation of VHF/UHF.

Various methods of signal propagation were discussed which differ somewhat from those on HF,especially meteor scatter, aurora reflections and various propagations via ducting.

The onset of digital methods makes communications at VHF and UHF less tedious than in the past, since signals too weak to be audible can be copied.

A small USB SDR was demonstrated and worked exceptionally well considering it’s very low cost and ease of use.
