Hmmm, that's an awfully big capacitor hanging off of pin 10. I assume that "COS out" is used to drive some visual indicator, as the 2.2 µF cap. will prevent really fast short squelch (< 3 millisecond) closing action. FWIW, I never use pin 10 at all; the circuit I've been using is at http://www.tasma.org/micorsq.png. Bob NO6B
