I have a President Washington base that has low receive, I can hear station that are about 2 blocks away or so but nothing else, I tried cleaning the relay and still the same..Any Ideas would be appreciated..The RF meter does not indicate any stations are being received?? Thanks for your time Robert |

First thing is to make sure your not
having a coax or antenna problem. Did you
try other radios on the antenna and coax? |

I did install another radio and the antenna and coax is fine.. I am sure it is the Washington that has a problem..Thanks for the response.. I must have a resistor that is open or a bad electrolitic in the RF section?? Any more ideas would be appreciated.. |

Sounds like what's called the rf amp. I don't remember the tr # offhand but if you can find a block diagram on one of the cb sites it will point the # out. It's usually a 2sc 1674 tr.
If that's not it check the ta 7222 audio chip bolted to the side of the case.
Hope that helps.

have you done a recieve alignment on it yet?
this would be my first step. the info should be around on the net for which coils to turn.
have you gotten a radio check with it?
does it transmit normally?
these radios have a FET front end in them and it could very well need replacing. they get damaged by too strong a signal, or by static.
i would find a SAMS manual on *bay, and go from there.
