[Repeater-Builder] Link-Comm - Micor carrier squelch timing (was GE squelch)

We solved the problem by using the onboard audio gating, which I see uses pins 6 7 of the Micor squelch IC. Maybe we can ask Link-Comm to do a timing test on their unit and then change the 2.2 uF capacitor on pin 10 to something else and see if it changes the attack/decay of the COS action?

I will see if I can perform that test on Monday AM and post the results. BTW, the typical propogation delay through all the controllers is less that 5mS, so pretty fast.
