Hi All,
I am trying to get my C Line to work QSK CW and am running into trouble with
the R4C's AGC. I have sped up the Fast release time but it's still too slow.
If I mute the R4C during transmit and unmute during receive, I get a loud POP
and THUMP in the audio everytime I release the key.
Mike -- as I recall there was a project described in CQ magazine way
back that provided for QSK in the C-line. I think it was fairly
complicated but supposedly did a good job. Someone here on the list
may have a copy. I'll search thru my files too if that's the kind of
solution you're
Hi All,
Another project I'd like to work on is better filtering for the R4B. I operate
primarily CW and the R4B's 400 cycle bandwidth skirts just doesn't cut it in
today's crowded bands. There was an article by David Sumner in June 1972
