Make sure the RF gain is on max.

If the meter is moving when receiving, but you don't hear it, it could be the mic. Try a different mic and see if it works. It could also be a broken wire to the mic jack.

If the meter doesn't swing when some one is transmitting to you and you don't hear them, there could be either something wrong in the receive section of the radio, a bad resistor in conjunction with the RF gain control, or it could just be a bad knob.

You can hot wire it to full to check it like this:

Look for the wires on the RF gain knob. Its 2 wires. Disconnect them form the knob and twist or solder them together. If you have receive after that its a bad knob.

You can replace it, or just solder the wires permenantly together and put some shrink tube on it and use it like that. You don't need RF gain any way.

Most of the time its on full any way. no need to turn it down.

Uniden grannt xl will not transmit


I can tell you that mic wires can simulate that problem when they accidently touch or ground out. Sometimes a ground is loose or capacitor leaks. Check standing wave ratio. SWR 1.5 or less prefer 1.2 or 1.3 read. Antenna cables replacement and new ends. Dirt in mic switch. Mine did this with a power mod capacitor
near final(without proper discharge 100 ohm resistor). I turned back power to 1 1/2 watts to 4 swing a Tx tuning slug *redpaint on it. I let it talk on low key an when i speak it jumps to 4 or 5 watts on meter. When a mod has been done some people don't know that capacitors discharge and it will leak back current. Thats why on a Cobra/Uniden company radio the instruction properly call for a 100 ohm resistor to be placed in parallel with Capacitor near final on bottom of circuit w/ capacitor on top spkr side(i call it top its on spkr side bottom when radio is upright (super mod kit). Or replace jumper J1 to factory deadkey of 4 watts and see no swing in talk except to 4.5 watt slightly(factory tune)

My cobra 29 turns on but i have no sound i can hear it key up and the meter swings speakerand mike are good could it be the finels


Are you sure its not on PA mode? And if the meter swings forwards its not a finale. It could be a bad soldier or IC chip. If you don't have it on PA to see if your IC chip is good take an external speaker plug it into your PA jack in the back turn on the PA switch and then key up the radio.Does it squeal or make any kind of noise if yes the the chip is good if no then there's your problem.If it is good Then its could be just a simple bad soldier.
