I can hear other CB's perfectly. No problems with reception that I can detect.
I can transmit a signal as usual, meaning other CBs can hear me key the transmit button , but no voice is sent.
This CB is on a Honda Goldwing motorcycle..I have tried 2 different headsets so that should eliminate a microphone problem.
Try a hand mic with the set, there may be a short within the radio.If not your problem is with the audio amp in the radio itself.Repair should be about $15.00.
I have had several cobra 29 ltd classics with this very same problem.the main repair that was done was 1= tr17 shorted 2= mic gain pot not responding replaced,3= t1 audio modulator has to be the number one cause in many of my repairs.these three are worth checking and very well maybe your fix.

First, lets make sure that the unit does transmit. Get a power meter and see how much power it transmits. If no power is being radiated, you need to have a technician check out the unit. If you have power then pick a less crowded time to test out if anyone can hear you. Other people with more powerful equipments can only be a problem when you are transmitting on the same channel and both of you happen to transmit at the same time all the time. Chances are remote that this is your problem. Good luck. es
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.
Mic may have audio wire broken in cord at mic plug wire solder connection.
Stock 1- Shield 2- Audio 3- Transmit 4- Receive notice the numbers on the black plug after you pull it out of the radio.
You probably should inspect the CB antenna and connections.....I would really recommend not trying to transmit till its looked at as a bad antenna can draw too much power transmitting and could damage the CB.
Hi, my name is John. Try putting the unit on PA and PA speaker plugged in the back, try another cobra mic on it, if that does not do it, then we will look at the audio chip. Let me know how it goes, I will post the tools needed and procedure here. Hope this was very helpful....Rate this solution on the four thumbs-up....... John
What are the SWR's at? Have the every been checked? Chances are if you have never checked them, and don't know what an SWR is, then your transmit is blown out of the radio.
Yo need to tune the antenna length on every antenna for a cb radio. If it is not the correct length then you get what is called reflect. that is signal that doesn't radiate off the antenna and is reflected back to the radio and blows the transmit out.
You are connected to a power source that is inadequate, possibly a poor ground in the vehicle or an underrated power supply if using as a base. Oxidized connections on the fuse or fuseholder may also be the cause.
Hello.I have a similar situation on a Magnum 257 HP operating on SSB (AM and FM works fine). If i Transmit it works fine, but when i release the Mic button (after TX), in the bottom side were the RX level should be, it appear somth like a signal level 3 to 5 (constant and continous), but i can't get any reception at all. Only if i turn the TX power level to MAXand i transmit, then it goes back to reception, but not every time. Somtime after TX i need to push the mic button 2-3 times to make it recive somthing, but this wors only if the power level is over 60-70% an i repeat, only on SSB.Can i get some help with this issue?
Several things can cause poor reception. I have a few questions for you.
1. Have you tried measuring your SWR (standing wave ratio)? This helps give you an idea how well your transmission line and antenna are working.
2. Is this radio being used as a base or mobile? Do you have proper grounding on the antenna?
3. Pressing the mic button and seeing the radio indicate "transmit" does not always mean you are transmitting at full rated power. Have you tried transmitting through a wattmetter into a dummy load?
4. If the transmission line is good and the antenna is good, then I would suspect that something may be wrond with the receiver's front-end (sensitivity).
Receiver sensitivity can be checked by using a RF signal generator. Unfortunately you'll have to take the unit to a repair shop to have that checked. Try the other things I mentioned above. Let me know what you find and we'll go from there.
