Possibly, sounds like old fashioned feedback. It's when your radio squeals loudly when you are standing too close to the person that is transmitting. If the units in question were set up properly from the factory, feedback should be limited to only when you are standing right next to the person, and stopping when you get a couple of feet away. Sounds like your group of radios just need to be tweaked on the service monitor.

Midland cb 77-095


Is the mic plugged into the radio? Do you hear any hissing at all?Do you have an external speaker hooked to it if you do ,unhook it if not hook one to it , maybe your internal speaker is blown. Could be a switching diode.Could be your final . Could be you squelch knob isn't turned completely to the left or your RF gain isn't all the way to the right .

Midland 98 low /no audio until mic is depressed, but no signal bar


there is definatly a problem here. Could be a crack in the PCB ,a cold solder joint , a loose wire , antenna SWR to high to much voltage going into the radio from the power amp. Take it to a tech to find out whats wrong,he can fix it faster then I can tell you how to concidering I don't have the set in front of me.

There is a horrible echo whenever i try to record and then there's a loud noice that sounds like a very high-pitched whistle and i don't know what to do.


This type of audio feedback loop can happen on any mic if you are playing back audio at a loud volume on speakers that are close to the mic while the mic is on - which tends to happen on Skype calls. Try lowering your speaker volume or using headphones to hear the audio, then speak into mic, and the feedback should be reduced.

I just bought a cobra 18 wx st 40-channel base cb radio and when i talk in the mic it comes out all distorted on the other end ive tryed three different mics do you have any answeres


Well, someone could have over modulated it. Some trashy techs will cut resistors and do nothing more than make it sound icky and bleed all over. You can turn the mic gain a quarter way to the left from where you had it and see how that performs. A mic gain turned up all the way is OK for farther transitions but a mic gain turned up all the way to people much closer will sequel and sound what I call "mashed out" ( distorted. ) If this does not help then take it to a licensed tech to inspect as the fix will be from inside the radio. Also make sure your SWR is 1-1:5 and no higher than 2. You can loose distance from a high SWR and burn up your radio. Good luck.

A Midland 1001z with a 103 whip ant. They are both NEW. When I turned on the radio all I heard was like the power sound but no volume! I even tried a exturnal speaker! Nothing! Any IDEA's????


Is the mic good? If there is a problem with the mic, it will not put the radio into receive mode and you will hear nothing.

Also make sure the radio is not on PA mode, or make sure the squelch isn't too high.

there are also times when it is really quiet on the radio and you won't hear any static. keep this in mind.

When driving over rough ground my midland alan 48 plus multi cb will sometmes change channel on its own i wondered if this could be a mike problem as you can change channel from the mike


Check for loose buttons, could be something loose inside, if its changing on its own when its moving around could be from vibration that something has come loose.

When parked just try shaking the mic first if that doesnt do it shake the cb itself and see if the problem persists
