Hello everyone! First of all, I'm very new in electronics, I'm experimenting and learning.
I'm starting to put together this Telephone Microphones. They are very easy to do, just grab the two wires from the earpiece and solder them to a 1/4 inch jack, and viola!
The thing is the I mounted a volume potentiometer or a lowpass filter, and the issue appears. When I turn the pot up or down, it hums, like a mosquito going by your ear. When its on 10 or 0, the hum dissapears. I've tryed different wirings but nothing seems to work out. Also try to put a resistor, wich turned the hum down, but just a bit, it is still there. I'm using a B100K pot.
Cuold anybody know how can I solvethis problem? I'll attach the wiring that I'm using.
Thank you in advance!
