I HAVE A GALAXY DX 88 HL TALK BACK TO LOUD I WHAT TO DO AWAY WITH TALK BACK THE R189 WIRE IS NOT THERE

if you hooked it up its wrong but I assume you didn't.First of all talkback is a feature that allows you to hear your voiceand you don't5 need a radio check because you can tell by your own voice how your radio sounds if you want it to work on am you need to attach a 33ohm resistor from the positive to the neg of the external and pa plug ins. the talkback will be on all the time by the way.

Answer to question.

turn the talkback knob to the right and push it in to engage talkback.when you get the volume you want leave it alone .Now key the mic.You will probably hear a squeal coming from the speaker.Now turn the volume down on the talkback knob until the squeal goes away.If you run your RF gain wide open it may squeal also.

my galaxy 88 cb makes a popping noise through the speaker when I key up how do I solve this problem?

Your wish is my command!!!!!

POOF!

You will find it here.

You will need a good technician. I know of a few but I do not like you to spend money again and again. Email me at...... [email protected]

Sounds like byou blew the transmiter diode. Take it to a good CB shop and they can replace it. Most reliable ones will bench check for free.

RUSHING SOUND ?
1. Get the noise then disconnect the coax and see if noise goes away on receive, if noise goes away then address the ground on your antenna,
if noise still there then address the ground wire from power source

You'll need to take it to a repair shop. Because it transmits its under FCC rules so a certified tech needs to work on it.

Or take it back to where you got it and have them correct the problem.
