Thanks for that info Lou. I'll take a look at them. But since I got the 707 last year, I have tried dozens (well, lots) of different settings with those switches and the other two sets (FO and FE) in the VC, without getting the desired results. Those switches didn't switch between COM1 and COM2. The results I got by simply clicking on the volume knob have finally achieved this for me, that's why I am sharing the newly found way of doing it with everyone.

BTW. Still no nav lights on my 707's. I uninstalled, removed registry entries, downloaded new installers and then reinstalled them. It didn't help. I guess I need to submit a ticket. It's strange because I have strobe and beacon lights, just no nav lights. I have tried that with the 727 yet, but I'm not very optimistic about the chances of that working either.
