Nobody ever said anything about "talking" on different frequencies. There
are a few dozen spurious responses on the best designed receiver that will
take your ears off when the other person transmits on the other transceiver.
It takes one hell of a lot of engineering to keep #1 transmitter from
blowing the socks off of the #2 receiver.

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?


And I have the newest Garmin audio panel. The pilot and copliot can each
talk on different frequencies at the same time.
