Set the radio for simplex ptt monitor out buttons turn on radio make sure the other radios work with each other hold the monitor down if you hear white noise then you dont have the simplex duplex setup right and or try holding the monitor button in when other people are transmitting that would indicate a ctcss programming problem

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.

I have 2 cobras 29 radio always worked good till recently. Have a rk56 mic I can hear but can't talk. Mic keys up but they hear nothing bought a new 29 chrome digital read out and a new mic just a wood power mic. The light on the mic doesn't come on same thing keys up but no one can hear me. Swrs are good everything set good on the radii the new radio is not tuned yet but old one is. I have a 14 freightliner w/ the built in antennas on the roof could that be it. Thx jerseygrl


Sounds like the cable on the rk56 has failed, most cb shops will check that for ya with no charge

You said its a power mic and the red light doesn't come on? ....if not it needs a battery inside change or add a battery.

If you are saying that you put out a signal but they can't hear your voice, the battery in your microphone is dead or the 9 volt battery clip that plugs onto the battery may be broken. Try the battery first since a new battery should make the light come on and your voice to modulate your signal so people can hear you. :-) Mr. 44

Bell South 2250 one seems to be voice activated and other not voice activated.


To turn off sound activation press the menu button 3 times to enter VOX mode. The VOX icon should be flashing, then press the down button till the number of bars dissappear. Press the menu button to confirm the VOX off mode. You also can adjust the sensitivity of the VOX mode by how many bars are displayed, less bars equal less sensitivity. No bars and voice command is deactivated. Hope this helps.

No sound coming back


I'd buy another radio.Lot easier than fixing the audio section..Ic chips with 16 to 30 pins(agh) and it costs $50 for each part or repair and it may not solve it. A good Uniden or Cobra is only $75 at www.copperelectronics.com or at a flea market people sell old radios for $25

My cb radio is on but cant hear nothing sound is turn up but nothing come out


You didn't include the make / model CB you have, so I can only offer general suggestions. If these do not work, please provided the missing info. Start out by locating and setting the the Volume to a position between 1/4 and 1/2 way clockwise, the Squelch to fully counter-clockwise and the "RF Gain" to fully clockwise to "MAX". Check the position of the "PA / CB" switch and set to CB. When set to PA, both receive and transmit audio is sent directly to an outdoor speaker (instead of through the transmitter and antenna for reception by other radios). The PA speaker is usually connected to a jack at the rear of the radio. When the PA / CB switch is selected, the internal speaker is silenced even if there is no PA speaker connected.At this point, you should hear static or voices (with an antenna connected). Do not attempt to transmit without a properly tuned antenna connected. If no sound is heard, there's something else wrong.

Unexpected problem I have a problem on my IC2G. Before it was ok when I used my other radio and keep my IC2G on the locker and did nothing on it for almost 4 months. When I turn the radio on here it comes , it can transmit but no sound heard on the monitor and vice versa i use the monitor to transmit no sound is heared on my IC2G but the signal meter display is ok when you receive & transmit. According to my friend it just only a matter of adjustment on the VCO I don't know where i could find that. i tried to make a down squelch to check if there's an audible sound then it's ok so I don't know why it's becoming like this where it was not been falling down before. Pls help me to solve this problem...Thanks


NO leave the VCO alone its not the problem SQ thershold setings maybe the the cause check the manual if you have it
