I'd be interested in those results as I hope to fix a problem on my 1296MHz antenna soon, and aircraft reflection (Doppler) is definitely a problem on many other data modes on 23cm. Now, if we could crack extreme doppler, like Aurora on VHF or rain/hail/snow scatter on 10 and 24GHz, that would be a real step forward... Dave (G0DJA)
