Re: PSK31/AO-7



 About 2 years ago there were a group of us running PSK31 on AO40. We didn't
have any real  problems other then if there were 2 or 3 QSO's going on at
the same time it was hard to stay on the same one. It was great fun trying
to do so! But with 1 QSO going on it was trivial to doppler tune as you
worked the other station. Error rate, if I remember wasn't a  problem.....
