Hi Andy,

I have already had = QRPP JT9 QSOs on 472kHz some years ago.=C2=A0 Want to see how FT8 performs = by comparison. FT8 works well on 10m, 6m and 2m.
50Hz BW is fine = by me. Yes, I know JT9 should be better. 15 sec periods are helpful.

Don't jump on the FT8 bandw= agon just because everyone else is using it at HF

If yo= u fancy a try please give me a call on FT8. I shall try 472kHz FT8 this eve= ning probably after 1800z. I'll call CQ probably.
