CB Squeal When Transmitting

I receive signals very crisp and clear on all channels. However when I key the mic, whoever is receiving my signal, hears a very loud mono tone squeal. None of the controls have any affect on the noise, yet when I move the mic around in the cabin, the squeal changes tone. Also when I wrap my hand around the mic cord at the top where the coils begin, the squeal goes away, the digital power meter goes into the red, and I transmit just fine. I am using: New Midland 1001Z radio, original stock mic that came with the unit, 3 ft adjustable Firestik antenna and a Hood Channel Mount kit that includes 18 feet of Fire-Flex coaxial cable with the Fire-Ring connector.

I have the power connected to the fuse block under the hood and ran through the firewall using the supplied rubber grommet. I kept the ground wire short and found a nice ground near the steering arm. I have heard that shortening the coax cable affects the whole system so I kept it at the stock length. However since I am short on room, the excess slack is coiled up and stored behind a dash panel.

My guess for my problem is either the coiled up coax, the coax running along the hood channel, or bad grounding.

If it is a bad ground, how would I check for a solid ground? Also the antenna and mounting kit does not mention anything about grounding the antenna, do I need to do that with my set up? (See picture above) If so, how? Thanks for your help!
Comment by Rouge 2, posted on Mar 15, 2008 I have deduced it is not the coiled up excess coax because I stretched it out and still no change. The noise goes away if the antenna or coax cable is gripped by a human while the mic is keyed. Hopefully this helps narrow down my problem for someone.
I have a Dx-44 and get a squeal while transmitting. The final was upgraded to a Motorola MRF455 by previous owner. Radio is very strong and receives clear. Please advise.

    Ok, I'm confused, Are you talking about a problem with the Midland radio, the Galaxy, or both?

I believe the coiled coax may indeed be the problem. To check, try a temporary rerouting of the cable which eliminates the coils. Dave g.

Why is humming coming from speaker when mic is keyed?


this is strange as most times if a proper transmit key is depressed , then the radio switches from receive to transmit , the mfg know this would cause some great squeal from receiver /transmitting so close to a receiver so the part that is the receiver is muted to keep this from happening , id say there is some fault in the part that does this muting of receiver

Problem no squelch noise or speaker like its muted, but can hear weather ok shows receiving and ant ok


Since the radio cannot transmit on Weather bands, there is no need for the radio to detect if it is transmitting when receiving weather.
In CB mode (on CB channels) the radio will mute when transmitting. So... a guess is that it is muting, or transmitting all the time in CB mode. Check for a mic problem by removing the Mic from the radio ... if it receives CB with no mic connected, then there is an issue with the mic. Otherwise, unless the unit is in PA mode (public address mode) it is likely something internal and beyond the scope of this service.

Modulation being muffled could be the mic or it could be an adjustment in the unit.

I have a cobra 200. The receive is some distortied, Most signals appears to be overmodilating with normal volume.


When the signals you are receiving are too strong "over-modulated" turn back your RF which will turn down the sensitivity of your receiver. If they are still over-modulated it may well be the other person has their modulation turned up too high from changing the setting inside their radio, turning up their mic gain or having their power mic turned up too high.

How do u turn up a galaxy dx55v.


Hi, my name is John. Welcome to FixYa. Take off the cover, with the circuit side down, take a plastic tuning tool, you can get one at your local electronics store. turn your channel select to midway of the band. make sure your modulation is turned off. Key your mic and tune VR13 to the Maximum on the watt meter. this is for the power. Next, locate VR14 turn the modulation up, and say ahhhhhhhhh, repeat if needed. Thanks for choosing FixYa....John

Cb is Keying Down instead of keying up when trying to talk


if you are transmitting fine Don't worry about the meter. Get an external SWR meter, they are better anyway.

Also, make sure the the switch next to the meter is all the way up on s/rf setting. thats for signal power and receive strength.

CB Squeal When Transmitting


Grounding the antenna bracket is extremely important, if it's bolted into the metal frame or fender it should be OK. The coiled coax cable could be the culprit but that's only a remote possibility.Try running a separate groung wire from the radio mounting bracket (or one of the radio's cover screws if not using a bracket) to the CLOSEST vehicle ground...keep this a short as possible. Your problem is definitely caused by insufficient ground at either end of the coax, with the antenna side being more suspect.

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
