Then the slopbuckets intentionally zero in on the AM carriers, it's time for 
the old tactic Timtron calls "exit stage left."  Otherwise, I agree it's 
good practice for everyone in a QSO to stay zero beat.

My only problem is that with some antennas, the VFO signal isn't strong 
enough to hear in the rx and I have to temporarily switch to a different 
antenna while zero-beating.

With the advent of transceivers, many of the newer hams don't have a clue to 
the concept of zero-beating.
