Thank you... (this is very interesting to me)

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.

Incidentally, the Link-Comm board uses the 2.2 uF cap / pin 10 combination to drive the COS output buffer... FWIW

an SCom 7k. I've always attributed it to COS line propagation delay in the
controller, but perhaps the 2.2 µF cap is the major culprit. 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?
Steve or Allan - you out there?
