I think you should take this into a tech. It sounds like your channel switch is either defective or dirty. You may also be missing other channels.

Hello.I have a similar situation on a Magnum 257 HP operating on SSB (AM and FM works fine). If i Transmit it works fine, but when i release the Mic button (after TX), in the bottom side were the RX level should be, it appear somth like a signal level 3 to 5 (constant and continous), but i can't get any reception at all. Only if i turn the TX power level to MAXand i transmit, then it goes back to reception, but not every time. Somtime after TX i need to push the mic button 2-3 times to make it recive somthing, but this wors only if the power level is over 60-70% an i repeat, only on SSB.Can i get some help with this issue?

Check the SWR on the antenna system.

Remove the POWER or GROUND from the RX blocking diode next to the Audio Transformer.

If SSB works. then the AM - Regulator Transistor is bad.

I did a google search and the only CB shop I found was this one. Unfortunately there are not a lot of CB shops around any more. You may have to send it out to one for repair. Most do business over the internet now, and rely on shipping the radios. there are a bunch out there.

You can google any of these, or just CB repair.

Bells cb
Sparkys cb shack
radio active radios

There are a lot on the net that will do repairs via shipping.

The same way you would on any other radio.

Hi,

On most mobile communications equipment, it is best that:
1. the power leads are directly wired to the battery terminals;
2. the bracket and radio body are grounded to the chassis of the vehicle;
3. a braided grounding strip be used in addition to the negative power lead; and/or
4. a gutter or trunk lip mounted antenna be used rather than magnetic. Antennas are better made of metal rod (not fiberglass) such as those made by Daiwa, Maldol, Oscar, Hokushin and others. The mount itself should use high quality RG58 coaxial cable such as those by Belden and others.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.
