can aybody tell me how to change between COM1 and COM2 i cant seem to select com2 when online

Yes, this is my problem too... I still don't know the answer. But it seems only a problem in the 737ng 600/700 version.Maybe if we keep this topic alive somebody comes up with the answer?:-zhelp :-zhelp Also, I would like to hear them both! There is no switch and 'c' on the keyboard doesn't seem to work either :( Alwin

you can check your keystroke assignments in the FS Menu, they should work to select COM1 and COM2.If you've got the registered version of FSUIPC, I think you can assign keystrokes for that function that way as well.
