I have a Galaxy DX 66 - Its been my truck for around 6-7 years; running on CB Freq.s Just this winter it started jumping frequencies back and forth between 27.185 (Channel 19 on CB Freqs.) and 23.-24.350 around that area. I'm thinkin its just a loose solder, which i can fix, but i just don't know where it is. Where can i find a diagram
