Yep. I have been an FSK fan since the early '80's. Back then
you could usually tell, because a "newbie" using AFSK didn't
know how to adjust his gain (or ignored the instructions)
and splattered all over the band.
I am using FSK with the Pro and the PK-900 in contests. But
my blasted PTC-IIe does not use FSK. Maybe I need to buy a
new PTC-II? Only trouble is that you NEED AFSK for PSK31 and
Pactor-II. And those are good modes.

Bill,
That is EXACTLY the point and why the purists prefer "true"
FSK. True
FSK will not give you the "unwanted sidebands" and bogus
signals all up
and down the band you refer to above. If you do hear these
ghost
signals, you can bet the farm they are NOT running true FSK,
but rather
are running maladjusted AFSK...

P.S.
Another way to tell someone is running AFSK without a clue
is when they
plug the AFSK tones into an auxiliary jack and forget to
disable the
mike. You them hear over the air, "Mabel, bring me another
coffee..."
