RCI 2950 WORKS FOR ABOUT 3 MIN THEN STOPS TURN OFF FOR TEN MIN WORKS AGAIN

you are probably heating up the final at the high output and thats whats happening.Could also be somethig else.Take it to a tech and have them look at it.

Get some freeze spray and when it starts fading spray the components and see if it comes back. This is an overheating issue and not a battery issue

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

What kind of radio is it.. RCI?? or other.. IF its a rci 2950 stlye there is a pin on the panel of the radio inside. this will reset it back to 28mhz. then put it back, it may work. if it doesn't it will be a more major problem possibly.

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.

You either have a bad LCD display OR the connection for the LCD display is loose/off. Its impossible to tell what channel you are on with a 2950 without the screen working, but when you turn the channel knob do you hear any other cb transmitting on ANY channel?? This is a tough one!! I really need some more info on the radio.

Open the case and look at the area that the display is in (front of radio). Slightly wiggle all of the little plugs in that area. If you see the LCD screen come on or flash then you know where your problem lies. If not, then you're probably looking at buying a LCD display for the radio.

Good luck.

check the ground wires

Bad mic? dirty mic pins? If the mic is bad, you will have no receive.
