    Breaking the radio squelch would not make it more difficult to hear incoming radio transmissions. The symptoms that you describe are from breaking the intercom squelch. The white noise is cockpit noise. As the engine RPM increases, the cockpit noise increases until it reaches a point where the intercom squelch is broken. Try adjusting the intercom squelch at cruise RPM using the large knobs, left knob for pilot and right knob for copilot.

    Hi Joe, Thanks for your suggestion. What you say makes perfect sense. I tried turning up the pilot intercom squelch before but I may have inadvertently left the copilot squelch low and the copilot headset connected. I'll check that next time I'm in the plane.

Does/can that >large cap have *adverse* effects? Thanks, Bob, as always. Haven't decided. I must acknowledge a level of risk for removing a component that really DID have some value at some point in time. But without seeing the numbers and understanding the idea behind the capacitor's original inclusion, I'm not prepared to offer any blanket opinion. But it will be the topic of a future study wherein there is a high probability of discovery of the capacitor's no-value-added existence. I'm aware of no potential for adverse effects so don't rush out and remove any that are already installed . . . Bob . . .
