That's exactly right. I kept getting emails with the owners manual and they kept telling me to go to a local dealer.... ummm my "local dealers" are truck parts stores and a truck stop that doesn't even work on radios. I couldn't get that through their heads... ugh! Wade

I am looking for a service manual for the Roadking RKCB Classic CB. I have tried relentlessly to get one from the manufacture with no success. Their customer service is horrible. Is there any one on here that has access to one or knows where to go to get one? Thanks in advance.

You said that was all you could find in your files, but by chance do you have any info like a voltage table for the trc-446? I'm digging through the schematic and getting further than I had before, but I would really like to have a voltage table or something to reference while I probe around in...

I have a subscription to Sams and have already downloaded that model. It is not quite the same as the radio I have. I wish it was... I see on their site there is an option to buy an OEM service manual, I may just try that if no one else can come up with some sort of information for me on here.

I am working on a Cobra 25LTD Classic that has been modified in the past by the previous owner. I am trying to "restore" this back to normal so I can proceed with an alignment and tune. I have downloaded about every schematic and wiring diagram that I have found, but each one is of course some...

Good evening. I'm looking for any information on the realistic TRC-427. Schematics, tune up points and procedures, anything and everything. I believe it is in Sams #274. Do you happen to have that book?
