if both sides are in the same band (VHF/VHFor UHF/UHF) what would be the 
point of continuing to scan during the APRS beacon, since all receivers 
on the same band would be either muted or totally blocked by the APRS 

Or do you mean that the scan fails to resume after the APRS beacon unkeys?

If the B-side frequency is inserted into the APRS beacon text and 
beaconed every time the scan stops and dwells on a B-side channel for a 
few seconds,  other APRS users are going to get a very "schitzy" effect, 
with the 710 user appearing to be randomly on a different repeater  
every time the APRS side beacons

It would appear to me that this feature of inserting the B-side 
frequency into APRS beacons is basically useless if the B-side is in 
scanning mode.     The firmware should automatically inhibit this 
feature unless it sees the B-side staying put on a single frequency for 
a specified amount of time (perhaps 1 minute or more).
