If you ground the audio wire, you will have no noise or mic function at all. The mic hot wire and the shield should be enough to avoid hum.

contact connex and they will give you a repair number and let you know where to send it.

Try replacing battery behind channel selector

Is the CB getting its power from the amp(?) By amp I will assume you are talking about a signal amplifier..

people think that if they peak and tune a radio it will work better. First, if its brand new from the factory you shouldn't have to,all you should have to do is lower the dead key raise the modulation and you are good to go . The proper way to do this is with a spectrom analyzer . Do you have one? Cheap on ebay ,may 4000-5000 dollars but if you get one and set that radio perfect you should hear anyone complain that you are interfering with their radio.

first of all if you do not have a ham license then you should even worry about getting on any band other than the AM band .

Your connex should have a know with letters on it A,B,C,D,E,F, Look at the counter and set that knob to C whick should be the CB frequency.

Hello As a general rule of thumb all radios should be connected directly to the vehicle 12 battery. This connection cuts down on vehicle induced noise and allows the radio to have access to the full current it needs to operate at full efficiency. Make sure there are matched fuses in the positive and negative leads going to the radio. Hope this answers your question.

On the RF Hi Lo switch do you have power? Is the switch ok? That switch regulates the TX power and if it is open, you have none.

lack of a noise filter on the DC voltage supply to the radio http://www.jaycar.com.au/Sight-%26-Sound-Car/Car-Audio-Hardware/Car-Hardware-Accessories/10A-DC-Noise-Filter-(Improved)/p/AA3074 or lack of grounding maybe https://www.youtube.com/watch?v=dY3gD-j4SVs

Is there any RF being transmitted, to a nearby radio. also does the TX/RX led change. There are many scenarios on this.. Loose/cold solder joints on the board. loose diode on solder side of the IF area.. Bad RF transistors from High SWR.. if you can provide more info.

If you must use echo.. please use a dummy load. while adjusting the amount of echo.. you want it to be intelligible to the other listeners.. just barley add the echo effect and it should sound great and not like your in a can or all running together were no one can understand you...

this usually just blows the fuse, check/replace and try again, if it pops the fuse, the protection diode has shorted and the radio needs to be serviced
