I may have a website all about CB's and repairs but I will be the first to admit I do not know it all. With some rigs I have very little
experience so have made this page up to ASK FOR YOUR HELP. None of us know all there is to know but some of us know more
about some rigs than others and vice versa.


I still buy CB's but I tend to buy them to keep these days, I like to get a cheap bargain, get it working OK then save it to the collection I have. This leads to the
downside that sometimes I get a damaged radio I can't fix or am not sure about. Rather than scrap them, which in many cases I could and get more
selling the parts for spares, there are certain rigs, namely the better models, I would rather keep and not scrap. This page is me asking for pointers and
help on things I have in the workshop that I would like to see repaired.
If you can help please EMAIL me on mag2781@yahoo.com

Right, to start things off I have a Uniden 400 PR27GB in pretty good condition
cosmetically. Looking at the board it also looks in pretty good shape. I changed
the protection diode as a matter of course and the one I took out was fine. No
signs of cross connection, no signs of 24v exposure, No signs of butchery.

Whats wrong? I turn it on and there is NO channel display and the RX and TX
lights are both illuminated at the same time. I plug in a Uniden wired mic and
nothing. No sound at all however when I press TX the RX light does go out. It
does not transmit. There is no sound from the extension speaker and it doesn't
appear to be on any channel. ANY IDEAS? The board is a
