I posted this question on the PMDG forum and no replies after some 19 views. Maybe someone here can help.How does one activate the COMM 2 radio? I can't seem to find the switch to activate it. Or is it a key assignment? Don't remember ever seeing one for comm activation or nav radio activation. For selecting to change frequencies, yes.Thanks ahead of time.

On the Radio panel under mic selectYou can switch using VHF1 or VHF2Cheers

Thanks, but I don't see "Mic Select" on the radio panel. I see it in the VC, and those buttons are not functionable, but they don't appear on my radio panel. (see Screenie) This is the panel from the 600/700 NG. Maybe it's on the 800/900 series.http://forums.avsim.net/user_files/160980.jpgJim

My Bad sorry.Your right that would be on the 800/900 upgrade.Cheers

Well I can accomplish this by assigning a key stroke or button on my CH QT.Right now I'm having a problem getting the Flaps to work with one of the QT's axis levers. The flap lever on the 737's panel view keeps jumping around. I checked sensitivities and assignments and calibrated and still doesn't work right. Any suggestions?Jim
