I'd wonder if you want AFC on at all when CQing. If more than one
caller calls you at the same time, what frequency will the program
tune to?
You also might have nearby QRM that might cause the AFC to drift away
from the CQ frequency.
Would it be better to use a narrow filter and adjust for off-
frequency callers by using RIT? I've also found that RTTY
demodulators produce pretty good copy even if you are many dozen of
Hz off frequency. This is what I've done in my limited RTTY experience.
Naturally, your error-rate will be lower if the frequency is dead-on.
