selecting COM1 or COM2 for transmitting

Yes, this is still the case in XP11, nothing has changed from XP10. The stock audio panel changes the RECEIVE setting only. To change the TX radio selection, you need to trigger the "Transmit audio: COM1" or "Transmit audio: COM2" commands as shown in this xp11 dialogue...

This is no different than what I outlined for XP10, but I figured I'd show you the XP11 equivalent for clarity.

And yes, by triggering those commands, it will actually reset the receive settings, too (this is stock behavior for Xplane's audio panel unfortunately). That is, if you were receiving on COM1 and COM2, then you swap the TX radio, the RX settings will change to match the TX settings (ie, you'll only be receiving on COM1 or COM2). If you want to continue receiving on both radios after changing the TX radio, then you need to click the button again on the audio panel for the unselected radio.

In the example above, I mapped ALT-1 and ALT-2 to toggle between having COM1 or COM2 selected for transmitting.

Thank you Keith

This is actually a pain that even the latest xplane doesnt do the right thing to simulate real world behaviour. I thought it was FAA approved software generally..

If you buy a hardware radio panel and attach that to your computer does xplane do a better job in this respect as a matter of interest ?

This post is very clear about how to select COM1/2 for PE transmitting. Great job!

I have some questions on the receiving side.

I am sometimes told to "monitor Ground" by PE Tower controllers. How do I do this in XP? If my aircraft only supports receiving on one radio at a time, then I am certainly not able to monitor another frequency. But suppose it does support two radios simultaneously, will COM2 receive the PE audio stream while COM1 is also receiving (and used for PE transmitting)?

Another question: Suppose COM1 receiving is OFF and COM2 receiving is ON. When PE is set to COM1 transmission, will the controller hear me but I cannot hear him (unless COM2 has the same frequency as COM1)?

"monitor ground" doesn't imply that you should remain on the current frequency AND monitor ground. ATC never assumes you have two radios, nor is there an operational requirement for them to instruct you to be on two freqs at once.

So "monitor ground" is like "contact ground" except you don't check in on the new freq.

Regarding what happens if you're not receiving on the radio which you've selected for transmitting...ATC won't hear you as we move you to another voice room if your radio is not configured to receive anything. So, you're transmitting, technically, but you're doing it in a dead room.

It's really good to know! Thanks.
