If the link requires PL, then turn off the PL when there is no COS from a
user. (Many controllers can be rigged to implement this, or you can make a
circuit to mute PL driven off COS gone). This dead hang time after a user
lets up is usually when the repeater tries to ID. The distant repeater wont
repeat it since it doesn't hear PL on the signal.

However, normally if the link radio is established on a 'remote-base' port
of both systems, the controller is usually programmed to not send ID audio
down a remote base port, so no Id-overlay problem.

Subject: [Repeater-Builder] Linking Question





In my quest to learn about building my first repeater, I have thought
of a potential problem.

If I wanted to set up an RF link to another repeater, how do you
overcome the potential problem of each of the repeaters ID'ing
(walking on each other) at the same time. (I could see this happening
if both repeater sites were idle at time of key-up.  (Given that most
repeaters ID in 10 minute intervels). Is there something that should
be done during construction?

Thanks.
