Hi 🙂  I'm only seeing the volume dial functioning.  The COM1/COM2 switch only restarts the ATIS broadcast instead of switching the focus to each com.

That makes me think the analog Com 2 radio is not functional since the com switch doesn't seem right.  I realize Com 2 is already limited to not tuning 3 decimal frequencies

Do to a limitation you need to set the rotary transmit knot to the com that you want to transmit and receive. But you also need to set the com receive switches to the same as the transmit. 

So for example if you want to receive on com 1:

Rotary = com1
switch com1 = up or down for on.
switch com2 = center for off.

So for example if you want to receive on com 2:

Rotary = com2
switch com1 = center for off.
switch com2 = up or down for on.

Thanks for the help!  I did tune the ATIS on COM2 but it only made odd noises.  It is 3 decimal place so maybe not possible.  Tried again later with no sound.

Then I tuned COM1 to ATIS and it played even though the audio panel was still set to COM2.

Later it seemed to toggle correctly.

Then when I set the audio panel to COM1 and COM1 radio to ATIS, then toggling the COM1 speaker off it continues to play.

NAV2:  I cannot pick up nearby VORs on NAV2 that NAV1 picks up.  Guessing that's a MSFS 24 bug.

For this aircraft, I would love a list of items known to work properly and those that don't.  It is taking me forever to understand the panel's limitations.
