Thanks for the clarification Bill. I wasn't aware of the difference in
AFC behaviour between FSK and AFSK. Yes, I'm using AFSK and no one
seemed to have trouble copying me when I called so guess I was at least
close enough for their AFC to grab me.
I think I've heard people saying that FSK was better than AFSK, although
they didn't say why except for the potential problem of overdriving the
rig and having people all up and down the band calling you. Being able
to use the narrow filters in the MkV and speeding up S&P with Rx and Tx
AFC seem to me like overwhelmingly powerful arguments in favour of AFSK.
BTW, had a new ticket newbie show up for ARRL RU. Actually got him
running. Once he got the hang of it he said, "Hmm... this is pretty
addictive." Hah, think I might have hooked another one.
