Cool radio conversion: Convert your AM/FM radio to recieve Aircraft Broadcast

[TFFTM 1]

I haven't tried this yet but I hear d it works.

Convert your AM/FM (Non-digital) radio to an Aircraft broadcast receiver.

I recommend doing this with a battery operated radio so you don’t fry yourself.


Open the case and look at the part under the tuning dial that selects stations. This is the variable capacitor. You should also see 2 or 3 small square metal components which are filter transformers. Look closely at the filter transformers and you will see a small srew slot to make adjustments. One of the filter transformers will have 2 or 3 small glass diodes next to it. This is the transformer that will need to be adjusted.

First tune the radio on an FM band between stations until you hear a background hiss.
Now adjust the filter transformer and turn it until the hiss gets as loud a possible. When the hiss is at its loudest point you have converted the FM portion to receive AM signals.

Next look at the radios tuning dial and notice the large tuning capacitor on the main board the will be 2 small copper wire coils next to it, with the screwdriver carefully spread the small coils out as mush as possible without letting them touch another part of the board.
You have now extended the broadcast range from 88 MHz to 108 MHz and above.

Next tune the dial up and down the FM band and you will notice that the station locations have moved. You should now be able to tune in aircraft frequencies.

To change the radio back, just reverse the instructions.

I have an easier way. I turn on my aircraft band transceiver.
