The output section has a problem which is detected by the circuitry and the entire unit is in "protect" mode. This mode effectively shuts off the output. If you don't have electronics repair experience, I'd suggest that you bring this unit to a service shop. Expect a parts cost in the $25-$45 range.

CB Plays out PA Speaker


it is possible that the PA speaker output is intended for a normal (unpowered, unamplified) speaker. Perhaps in your case the audio you hear from the PA speaker is only signal leakage from the PA Speaker connection.
To know.. connect a regular speaker to the PA speaker connector (any speaker, home audio, old car 6x9....). If the PA works and drives the temporary speaker OK, and you hear no CB receive, then the PA output is for a normal speaker, with leakage of CB audio.
It is just a guess, but easy to try.

CB Plays out PA Speaker


Are you following the user manual that came with the radio?
NB-ANL/CB/PA SWITCH: When the switch is in the NB/ANL position, the Noise Blanker (NB) and Automatic Noise Limiter (ANL) circuits are activated.
The Noise Blanker is very effective in eliminating repetitive impulse noise such as ignition interference. In the CB position, the PA function is disabled and the radio will transmit and receive on the speaker that is connected. In the PA position,
the radio acts as public address amplifier. Your voice will come out of the speaker that is plugged into the PA. SP. jack on the rear panel. The radio does not operate when you are in the PA mode.

When you plug a speaker into the ext. jack does it kill the radios internal speaker? It should until you unplug it; if not and you are following the about you may have a wiring issue with the jacks.

How do i get rid of the 60 cycle hum on our building PA speakers? We are using a Speco PBM-30 amp. A two-way radio audio is the feed.


That sounds like mains hum! Most amps have large electrolytic capacitors to take it out. They can go faulty and let it in. They are high value often around 2,200 or 4,700 UF or higher.

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.
