Just because its a magnet mount doesn't mean its a 100%. I've sold 4 little wheels made by wilson in the past 2 months and they had a ground problem. If you grab the base of the antenna does it give you more squesh? If so it has a ground problem. Have you had that antenna matched to you truck if not that could be your problem. You need to have your SWR checked on your antenna.

Background noise problem with motorola radius cp200 and also crackling status during transmissions


Bill,
If the crackling and static are coming from the radio, it could mean 1) Something in your environment is putting out RF (radio frequency waves). 2) You have an old battery. 3) You are at the edge of the radio's range. 4) You have a bad speaker in the radio.

Possible solutions for you could be:
1) Have the radios reprogrammed to have Private Line (PL). This would block out RF noise on your frequency. Also, within the factory if there are devices putting out RF noise, there may be some solutions for them.
2) Replace old batteries. (Try a known good battery and see if it helps.)
3) Check to see if you have the same problem when radios are within a closer range. If it is a range problem, education yourself and other users to hold the radio upright (perpendicular) to the ground. You will get the best range. Tilting the radio can reduce range as much as 2/3s. Even the bodyfluid of a person wearing the radio can absorb range.
4) See if you have the same problem with another radio, or if the crackling static is just with the one radio. It may need repaired.

Another solution for you might be a noise canceling remote speaker mic. This would put the speaker of the radio up on your lapel. And these mics also have some noise/wind canceling ability.

There are a few programming things you could have your local dealer try. They may be able to tighten up the squelch and knock out some of the noise.

Best regards.

Turned up full volume u can only just hear sound if ear right to it was working fine then the volume just ******** out


It could be the mic plug. uniden is known for the issue where the wires inside the mix plug break at the solder joints.

When the RX wire breaks, you will loose receive because the radio will not go into receive mode. But you can usually hear it ever so slightly if you crank the volume.

Other issue that may cause this. No radio activity, (unless you hear radio activity low and not static)

poor feed line or antenna.

I would try a different mic that is known to work.

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.

Can recieve but not transmit


The mic wires are soldered incorrectly. Get another cobra mic for that radio or have a qualified radio tech correct the wiring.

Check the squelch on your radio thats not recieving. If there is a monitor button ( when pushed you will hear static) try pushing it.. then get someone to call you so you can check if you can hear them. On these radios you have 2 types of squelch....1 is called carrier squelch.... it basically opens when there is a strong enough signal. This lets you only hear strong signals and "squelch out" the distant ones and background static. The2nd. is "tone squelch" ... with your radio they are often called privacy tones. If you have 2 radios set with the same privacy tones you will only be able to hear each other... only radios that are transmitting with that privacy tone will be heard on your radio. Its a high frequency tone that can't be hear by the human ear that gets "embeded" with the transmitting signal. The recieving radio hears it and opens the squelch. So... if the radio thats rxing (recieving)your signal has its squelch set for just carrier squelch it will hear any signal thats strong enough to break the squech open.... basicaly any radio within a certain range. But if your radio (one with problem) has its squelch set for privacy tones you will not hear any other radios except the ones set with the same privacy tone.... the squelch will not open until it gets a tx signal with the right tone.... so if the txing (transmitting) radio is not using tone squelch but is using carrier squelch.... and the rxing radio is set for tone squelch... the rxing radio will not hear it. With tone (privacy tones/codes) squelch you need a tone to open the squelch and then the audio can be heard... with carrier squelch the squelch will open if ANY radio is within a certain range. Check the squelch setting on the problem radio... it could have a privacy tone set. Try pushing in the monitor button so you can hear static ( you want to hear everything including static) on both radios... tx on one radio at a time and listen if it can be heard on the other with the monitor button pushed. If you can't hear any audio when the broken one is transmitting then it COULD be the mic.... if you can hear both radios with the monitor button activated than the radios are txing and have tx audio and are working... if thats the case its the privacy tones that are the problem. Take care
