When I entered the hobby I had a PC active speakers and when turned on I was hearing FM broadcasts on 88-108mhz. Then I placed speakers and the circuitry in a metal box and FM stations disappeared. Use aluminum foil I'm case you have a plastic enclosure to see if this might help.

I haven¡¯t solved this issue yet. I attached a ground wire to my EFHW antenna, and that didn¡¯t help. I pulled the lm386 chip out and it looked fine and I put it back in. I don¡¯t have any other rigs to confirm it¡¯s not my antenna. Nothing happens if I touch the extra coils of wire.?
