After my Galaxy DX2517 has been on when somebody transmits I hear a high pitch coming in with it. After trying to research this I found that someone said to flip off the NB/ANL and it goes away. I tried it and it did work. If I let if off for a little bit I can flip it back on and be ok for a while. I understand it is a capacitor getting weak but I cannot figure out which one. Can you identify which capacitor I would need to replace to solve this problem??
