I built an audio amp out of the LM386 on a previous question. I when I have nothing connected, I picked up FM radio stations, as well as AM Very loud and clear. Why is this happening? Why AM and FM?
How can I prevent this? Although it is very cool that I picked up the stations, I don't want to have any interference.
I live in Evergreen, Colorado (just west of Denver), and I am picking up 105.1 FM as well as 850 KOA AM
Yes I am sure that the one is FM because I heard them say "KOOL 105!!!!"
