I try to use that pin when I can, and prefer it over the open emitter

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

Really! I noticed some decay problems with an RLC-MOT we have on 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?
