Where can I get a cpu board for my ranger 2950?

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

• 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.

i have the same radio rci 2950. Ive had the same problem with mine,turns out with mine the processor would lock up,turning the radio off & on repeadly would clear the problem and the radio would work fine x-mit & recieve. the solution to fixing the problem is to replace the memory backup battery this battery works similar to a computer motherboard cmos battery when this battery goes dead all sorts of strange things happen to the radio wont transmit wont recieve or like your problem transmits continiously. the problem with replacing this battery is finding out what year & model your ranger 2950 is. the internet says only first generation ranger 2950s use the battery second genration & third generation do not use the battery. but the internet could be wrong. so i suggest getting a hold of (usa ranger.com) & give them a phone call or email and ask them about the year your radio was made. they may even service it for you or if you are electronic savvy you can do it yourself. the battery is located close to the main cpu on the front panel if yours uses a battery.

If it was working fine before storage it is most likely electrolytic capacitors. These "can" looking things that are all over the circuit board. These little cans are filled with electrolyte like a battery. If this leaks out or evaporated as they are known to do they will render useless or degrade circuit voltage and current in circuit.

You put it on the CPU board, its called a (E-CHIP) if yours did not come with one, may be hard to find...You have to have a good steady soldering hand to do it. Have not done any of these, but did a few 2900 DX. ... hope this was helpful...

check the ground wires

Hello, Just offhand I'd say you have a bad solder joint on the main circuit board. Without more info, I can not tell you where to look,,,,, Mechanic
