For what it's worth:  IMO, AFC should NEVER be used during a contest
and here's why.

When you're doing S&P and tuning across the band, AFC will reach out
and "grab" the other station before you have it correctly tuned in.
As a result, your TX frequency will be off from your RX frequency by a
certain amount.  The only way to compensate for this is if you're
using AFSK, you can turn on both AFC and NET, but why bother since you
need to turn them both off when CQing.  Just use RIT for what it was
intended.  Actually, I don't even use RIT.  When CQing I use split A
and B VFO's, thereby allowing me to tune with the big knob instead of
the little one.  Either way is better than AFC/NET.

AFC and NET:  Spawn of the devil.  :-)
