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
