I need a manual to base station CB Ranger rci-2990. Can you tell me where to download or purchase this manual. Thanks

Mic Wiring Info
Stock Mic Wiring
1. Ground Shield
2. Audio Yellow
3. Transmit Red
4. Receive Black
5. CH. Up White
6. CH. Down Blue

it could be several things......the rf final,bad mic,cold solder joint on the circuit board just to name a few.my suggestion is to find a good local cb shop,if no local shop find one along the interstate hwy most of the time they are located around or near some of the larger truck stops. tell the tech there what the problem is and go from there. good luck !!

have you tried it on all bands? still won't transmit?take it to a tech so they can fix it properly.

If on all modes check the mic first to see if wired right or wires broken--this should have am-fm-lsb-usb---which works or do not work.

• These boards are hard to find. If any place stocks them new it is Maycom http://maycomcomm.com/ I have bought lots of Galaxy boards from there.

• I have also gone chicken hunting before and just start randomly calling CB shops and see if they have one for sale from one of their parts radios. One time I could not find a heat sink anywhere and they were going for $25 new if one did pop up somewhere. I landed 4 like new radio heat sinks with hardware shipped for $10. So this method can pay off with some persistence.

• Also the board out of a Galaxy 2527 or an RCI 2990 will work as well. Ranger often stocks these parts too you just have to already know this. So give them a ring too http://www.rangerusa.com/ and ask about the RCI 2990 board. Of course I recommend you exhaust all options for the OEM board first.
  

• Hope this helps.

you have hooked it up backwards. You blew the polarity protection diode. It needs to be replaced.

You can download and print the operating manual for your 10-meter transceiver here:
