• For those integrating Motorola SpectraTac or DigiTac with non Motorola receivers or Motorola receivers lacking the C269 option. Those voters require 15 ms of silence after the status tone drops and before voice appears on the circuit. Without this "tag", the AGC will wander aimlessly. You will probably not find this documented anywhere else, but buried in the receiver C269 option will be a mute circuit and timer. I am not sure any of the aftermarket status tone encoders consider this. So unless you are prepared to cobble up this arrangement on your brand X, stay away from those voters.

There’s no reason to keep AGC when using a backhaul that you have level-control over, i.e. if you’re usting most anything other than analog telco circuits.? Disabling the AGC is the first thing you should do when using a SpectraTAC with RF links or any other backhaul where you don’t want, or can’t have, status tone up all the time.

The mods to use SpectraTAC voters with COR are well-documented on the repeater-builder web site and elsewhere.? GE voters are even easier.
