I finished my receiver last night, and the quality is fair.
I did experiment with my receiver, and noticed that when I add an antenna to my speaker connection point, the station fades out. The same applies if I add an antenna directly to +ve. The radio is connected to my computer through end-to-end speaker cable.
Other than connecting the speaker connections together with a capacitor, is there any other way I can prevent interference from happening?
My guess is to make a PI filter, and I think I should make it pass anything between 120Hz and 20Khz.
I notice the interference the most when I move my long speaker wire around, or when my long speaker wire is in the wrong position.
