Sometimes when you get a new panel for your plane, you find that you cannot tune the COM or NAV radios (ADF and Xpndr work fine). And you think "I've just downloaded this panel and it don't work - I'll have to get rid of it."
Here's the fix: Go to the problem aircraft and open its aircraft.cfg file in Notepad (make a backup first). Scroll to the section below.
[Radios]
// Radio Type = availiable, standby frequency, has glide slope
Audio.1 = 1
Com.1 = 1, 1
Com.2 = 1, 1
Nav.1 = 1, 1, 1
Nav.2 = 1, 1, 0
Adf.1 = 1
Transponder.1 = 1
Marker.1 = 1
If the COM1 radio is not tunable, then change the Navy "1" to "0".
COM2: same for the green
NAV1: same for the red.
NAV2: same for the orange.
Save the file and the problem should be fixed.
Only do this if the radios don't work in the 1st place.
Good Luck
