The so-called "split" function exists on the KMA28, made by PS
Engineering, as well as of course the PS Engineering branded audio
panels with built-in intercoms.

I've a KMA28, and on a few occasions I've been talking to ATC on the
pilot side, while a friend would be calling an FBO on their ARINC
frequency to arrange for a car, or whatever.

I find it interesting that the PS Engineering KMA28 documentation
fails to mention this 'split function':

I also have the KMA-28, and it's the same as the PMA-7000, and does have the split mode. Here's some
better links:

For me, the split mode works as advertised, and is OK, but is subject to cross-talk between the two
comm radios. On my plane, the two antennas are side by side, and only about 2 or 3 feet apart, so I do
get some interference. (Not to mention the two radios being side by side in the stack, so that's another
possible cause.)
