Re: cant hear

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.

Good luck,

- Jim

Chris Millett I want to know. If I want to turn a 4 meter handheld two way radio into a vhf tv transmitter, can I use radio shack's tv modulator?

It can't be done. You can't turn an audio receiver / transmitter into a video transmitter. Give your head a shake!

Plus if you want to transmit anything especially video over air, you have to be fully licensed and registered.

Have a general lee transmittes.canhear myself talking but cant hear any response,changed mic,antan,coaix,still no change,need help

See if you can connect an external speaker and see if you get received audio. You might also see if you can connect directly to the audio output on the main board directly to see if there is detected audio.

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.

Hi we just bought a new cb galaxy people can hear us we cant hear anything no squelch no talking

Plug an external speaker in the back of radio & see if you can hear anything. Also,you may want to take bottom speaker panel off & make sure the 2 wires coming off speaker are plugged in to the back rightside of radio. These things I would check first.

Cb puts out good sound but when someone try to talk to me it all you hear is static

same thing sometimes happens to me. Usually it is because the person who is talking to you might have a weaker antenna. Sometimes people put a very strong transmitter with them and talk to people but you cant talk back.
So really they can't hear you good either. Just because you are too far away.

Low transmit audio cobra 29 ltd nw

Are you talking about this radio or what others are hearing from your radio?

My friend, no one but the holder of a 1st class FCC radio license is permitted to adjust the input power to the final amp. Further, one needs some pretty technical equipment to accomplish this fine tune adjustment. Failure to properly set this envelope will result in degraded operation and possible failure of your radio.

If you can't live with the present circumstance, get your radio profesionally repaired.

Thank you for your quesiton at

My cb transmits with a very weak signal and won't recieve anything. The weather band recieves with no problems. I couldn't even pick up a signal on my SWR meter but a friend of mine tested it on his home...

There are a few things that could be wrong. If there is something wrong with the mic, you may not hear anything on the radio. but weather will work.

Other then that, the receive section of the radio could be blown.

Try a new mic, and if it doesn't work, then there is something blown in the radio. It needs a tech.

No response to radio check

Try this: find another CB radio and tune it into the same channel as the other one and talk on the one you have trouble with and if you hear yourself on the other CB, your radio is fine. But if no one can hear you, you might need to find a better antenna, I'd recommend Shakespear or Moonraker antennas. They're pricey, but worth the money.
However, if you still can't hear your voice on another radio, you may have either a Mic problem or a Transmitter problem. If so, use a different Mic and see if that solves the problem. If not, you may need to get another transmitter or new radio.

Best Regards,
