50MHz FT8 and aircraft scatter
24 July 2017 | by Playing with the new FT8 mode on 50MHz, I spotted something interesting on semi-local signals affected by aircraft scatter. On JT65A, I notice quite a few UK stations affected by aircraft scatter – you can always tell by a slight (sometimes more than slight!) slant to the main trace.
What’s interesting on FT8 is that you get two separate decodes – one of the main signal and one of the reflected signal. Look at this screenshot and the signals from G0GGG
I have had quite a lot of success working UK stations on JT65A via aircraft scatter, although some overs have so much doppler that the decoder simply can’t cope. Maybe FT8 will offer some more possibilities.
