Kjetil,

Good question! I have not been able to receive the audio from the VOR or ADF. I use the meter to see if there is an indication of signal, but the Gain or BFO does not seem to do anything. The distance for receiving a LOM NDB seems to be around 20 miles.

Try this; at a commercial airport with a NDB. While on the ground at the airport, tune in the NDB and see if you get an indication on the meeter and in the ADF instrument. Remember to flip the switch on the ADF to the ADF position.
