So i think i made a radio of some kind. I was trying to make a wav player and im picking up a sports broadcast.
The way to stop this is to place a small ceramic capacitor across the input as close to the chip as you can get. Anything between 100pF and 1nF should do it.
it was a cheap board. I couldn't beat the price but you do get what you pay for. I will try to use a ring but like i said i have nothing on the input line.
