Here is the lines I was talking to you about these lines are from the panel cfg file
ident=RADIO_STACK_PANEL
gauge01=Bendix_King_Radio!Bendix-King Radio Audio, 0, 0,250, 44
gauge02=Bendix_King_Radio!Bendix-King Radio Nav-Comm 1, 0, 45,250, 92
gauge04=Bendix_King_Radio!Bendix-King Radio ADF, 0,137,250, 65
gauge05=Bendix_King_Radio!Bendix-King Radio DME, 0,202,250, 65
gauge06=Bendix_King_Radio!Bendix-King Radio Xpndr, 0,267,250, 78
notice that in this case the gauge04 is the ADF gauge the numbers are where in the panel the gauge is at ignore them
Below are the lines that activate the radios
this is from the aircraft cfg file of the default KingAir
[Radios]
// Radio Type = available, standby frequency, has glide slope
Audio.1 = 1
Com.1 = 1, 0
Com.2 = 1, 0
Nav.1 = 1, 0, 1
Nav.2 = 1, 0, 0
Adf.1 = 1
Transponder.1 = 1
Marker.1 = 1
the number 1 means it is available if the Adf line is not here the gauge will not work.
The same holds true if the number is 0
as 1 is on and 0 is off
You need to check both
