"Somebody check your mike on the radio, please..."

hmmm... what I had in mind was a split (pilot/copilot) stack, but upon
further thought the transmitter would overwhelm the receiver, even
though the receiver is not switched off.

As Rosanne RosannaDanna would say, "never mind".

How about in a dual com situation, tx on com1 and rec on com2?

I believe Jose's (revised ) observation still holds. If COM1 is
transmitting, and COM2 will receive the most powerful transmitter, then in
the case of the airplane transmitting that would be COM1, not someone else
telling them to unstick their mic.

And in fact, that's the only reasonable interpretation of what Jose wrote,
since the only receiver available to receive when the transmitter on one is
stuck is the other. Reception is automatically disabled when transmitting
for the transmitting radio, so it wouldn't receive the other pilot's
transmission in any case. (All this assumes exactly two radios, of
course...a common enough configuration).

And if the stack has an audio panel worthy of the name, the opposite
transceiver's audio is cut off during transmit to prevent an unholy squeal
coming down the audio line of the receiver that is still operating.

You sure? I've operated split (on different frequencies), and not been
cut off when the other pilot was transmitting. Does the audio panel
know what frequencies each radio is using?

It has nothing to do with the audio panel. There is a "transmit
interconnect" wire between radios. It doesn't always get installed. I had to
have one retrofitted after completion of my Garmin 430---King KX-165A
installation.

With such an installation, wouldn't each pilot be frustrated while the
other pilot is transmitting, defeating much of the purpose of the split?

No, it works just fine. You can hear a little garbling if you are
talking on close frequencies like 122.75 and 122.8 The Garmin audio
panel does not shut down the receiver of the radio not being transmitted on.

That is remarkable receiver selectivity performance. What com
equipment do you have installed? Is it Garmin as well?

Excuse me, I design audio panels for a living and have done so for almost 40
years. DOn't tell me it has nothing to do with the audio panel. It has
EVERYTHING to do with the audio panel.
