If the other station has AFC on in their software, they tend to wander
around a bit. I tend NOT to run AFC if I am S&P, as I line right up
on them. If I am running and there is activity around me, it is hard
to run AFC, as my signal then wanders around. But if someone comes up
a bit off, or I have some room around me, I then run it. It then
aligns my frequency with theirs.
Its a lot like CW contests, where so many do not zero you before they
call.

I have been playing in the WAE RTTY contest. I am mainly using the 250Hz
roofing filter with DSP bandwidth at 300 Hz. I occasionally use the
1.8kHz filter with DSP set at about 500 Hz. In either configuration, I
find that I have to use the shift control to center signals in the
bandpass. Not sure if this is a hardware or software thing, but in any
case, I have two issues. One is that the minimum shift value is too
large to accomplish what I want to do at the narrow bandwidth, and when
I try to use the dual bandpass filter it appears that shift is disabled.
Am I missing something(highly likely), or do I have to request that
changes be added to the wish list?
