GE 3-5819a CB

[dilbert]

Hello

New member. Getting the CB bug again. I came across an old GE 3-5819a CB and came across some issues. Channels 1 through 10 don’t transmit but receive. 11 through 40 transmit and receive well.

I run a cobra 19 ultra iii with a tuned Wilson 1000 in my work van and can hear the GE clearly five or so miles out on the working channels and it receives me well. The SWR meter is WAY off on the GE but I have it tuned to 1.2 with a stand alone meter with another Wilson 1000 on my metal house roof.

Im looking for a service manual just to tinker with it and see what can be done to bring her back. Any source for those?

One of the best sources that I use for radio schematics is a site called CBTricks.com. Unfortunately, the listing for your model G.E. radio did not include a schematic. However, the 5819a model is very similar to some other model radios from other manufacturers. Here is the link to a schematic of a Lafayette radio that should be very close, if not identical to your radio:

As for your radio's inability to transmit below channel 10, assuming it hasn't been hacked up for extra channels and it's really on channels 1 thru 10, the most likely cause of the problem is a misadjusted VCO coil (L1 on the schematic). Usually a 1/4 turn is all you will need to snap those channels back. If you turn it the wrong way, you'll lose more channels, so simply turn it back the opposite way.

Thank you very much.

That did it. Thanks again.
