Mike,

What happens if you un-link all the ports on the RC-210?

In case you aren't aware the RC-210 sends courtesy tones/beeps on its 
own when ports are linked together. Depending on which port audio comes 
from unless you or someone else has reprogrammed (zero out) CT number 9 
and 10 on each port of the RC-210 you can possibly get different tones 
playing on your repeater when another linked port unkeys to let users 
know which port the Audio came from.

Could that possibly be something you are hearing other than beep tones 
coming from Allstar?
