Do you have speakers hookd into both the ext and pa connectors in the back of the the radio? If not try it , it should work.

Why doesn't my radio operate in the "PA" mode?


Some radio's do this (specifically Uniden) for some unknown reason. Ideally you plug a speaker into the PA output and when you switch to PA mode, the CB transceiver part should turn off and only your voice should come out of the PA EXT speaker to make it act like a personal megaphone.

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.

Pa problems


look on the back of the radio. See those two holes that you can plug a speaker into, well one is for CB the other if for PA. plug your Pa speaker into the appropriate connector and you have Pa capeablity. You must turn the switch to pa on front of radio.

Rf out ok no modulation but mike ok


Hook up a speaker to the PA jack on the back of the radio. Put the CB into PA mode and see if any audio is coming out of PA jack. This will tell you if the AUDIO AMP IC TA7222 is good.

Plug in an external speaker to the pa jack ... Switch the band selector to pa and see if you hear yourself... No? Bad audio chip

Set the squelch and knob to full counter-clockwise position. Turn the volume up to the 1/2 way point. Disconnect the external speaker plug from the jack. Disconnect any PA speaker plug from jack. Static / voices should be heard from internal speaker. If not disconnect the mic. Static / voices should be heard. If not, tune a different channel, sound should be heard. if not, look for indication of the radio stuck in transmit mode. If in transmit, there will be no sound until you can stop transmitting (hopefully while connected to a 50 ohm dummy load or suitable antenna - otherwise the final transistors may be blown). Reconnect accessories to determine problem component.

Good luck!

I can't hear.


I am not completely sure i understand whats going on. it seems like it could be a few things because of different parts of the question.

With my CB everyone else can hear me and the signal transmits fine
Good!
I have tested to see that my CB is picking up the signal
how? A meter on your radio should either light up or a needle should swing if you are receiving.
their voices don't play through my mic of my PA
A Mic is a microphone, i think you mean speaker.
Ok this may be the cause of the problem....
Try a couple of these.
First, unplug the PA Speaker, this simple act should make you to be able to hear the incoming signal.
Make sure the CB is on AM or CB not PA
If you can not hear the speaker may be busted or an internal part may be blown. (needing the expertise of a required technician)
If you can here when you do this make sure the speaker is working by plugging it into a computer. (mp3 players will barely put out enough power to make a sound audible) if this works, make sure you plug it into EXT not PA on the back of the radio.

one more thing to check. i dont know what radio you have but try turning it untill you hear static. if its all the way the other way you may not hear anything, also turn up any RX or rec. knobs.

i have limited knowledge about whats going on, but i hope this will help fixya
