I have a Uniden BC278CLT and it worked fine until I moved. Now there is a popping sound that sounds like someone is keying and releasing a mike every 4 or 5 seconds. When scanning, it will momentarily stop on certain channels and "pop". If locked on a channel that frequently has activity, it pops every few seconds when no one is talking. I have taken it to different rooms and even outside but it still does it. It's pretty much useless as is. I would buy a new one but I'm afraid it would do the same thing. Any ideas?
