GL1800 Goldwing with BikeMP3 cb. Intermittent issue. Somewtimes will TX and RX, other times even with squelch set to 1, nothing. Pinched wire or CB unit itself.

SOURCE: CB Base Station picking up electrical interference

i dont know what AC DC adator your using. you should look into a 12V power supply. or plugging that into a RF canceling power strip, like a monster power strip. TV's that are on or other appliances may cause high noise levels on the CB, make sure your coax is good, your antennas good, and all jumpers are good. its hard to tell with out looking at it, but do a quick once over of the system.... you are using a base antenna right? if not you need to create radials for a mobile you plan on using for a base.

Make sure the connectors on the coax are all on right, this causes problems a lot of the time. sometimes even brand new coax have bad connectors installed.

SOURCE: no squelch

Yep that should happen.
Green or no color in receive mode
Red when you key the mic to let you know when you are transmiting

SOURCE: transmitting and receiving

RF gain should be all the way up. Turn the squelch all the way down. Turn the ANL/NB to just ANL.

Turn the dynamic up at least 3/4.

Once you have confirm you can receive and transmit, then you can turn up the squelch up until white noise just stops.

Make sure you are on 19 by the highway. Key up and say break break one nine, can some one give me a radio check please.

you should get a response.

Your RF gain is how much you receive. the higher it is the more you receive. In normal operation there is no need for it ever to be less the all the way on.

Squelch is just to knock out fuzz, and if you only want to hear people close not far. A little less then half way is a basic setting.

the ANL switch is the automatic noise limiter. if you have interference from your vehicle, like engine noise, turning this on will quiet that. If it is extreme engine noise then switch it to NB, noise blanker. It is just a more intense setting.

your dynamic is how loud your audio is. if its low or all the way down, you will not transmit audio loud enough for people to hear. If its a stock radio and has not been tuned, if you turn it all the way up, that is fine.

Use trial and error systemathically. If still refuses to work, mike and radio aren't compatibles.

SOURCE: Red RX/TX and red ANT light on my CB

Well,first hand ,some cobra radio,s have red some have green RX/TX lights, but are you modulating? Some green lights turn red. What is your standing Wave on the antenna,s? You need to check it and the output of the radio. To do this you need a watt or field strenth meter. Can get one at Radio Shack. Your standing Wave is ok as long as it is below a 2. That has to be done on the antenna. ..hope this helps...

Testimonial: "Thx the rx/tx light is supposed to turn red I found out. Still trying to get the antenna prob fixed though."
