I have made FT8 contacts on 5760. However, on 10 GHz, even over 30 mile paths,
FT8 just will not decode. I believe it is due to frequency spreading from
multipathing. FT8 looks OK on the waterfall, on 10 Gigs. Sounds OK, out of the
speaker. But, it just will not decode. Any Q65 mode seems to work, just fine
for 10 GHz Tropo.

I have used FT8 as high as 2.3G. Doesn't work so well the higher you go in
frequency due to doppler and spreading.
I have used Q65-30B as high as 47G.
The Q65 modes are king when it comes to doppler and spreading and usually
work great when CW just won't cut it.
