SDS100 Noise on Conventional Channels

A few months ago, my SDS-100 began stopping on every conventional channel with a crackling sound, as if squelch (no matter how I set the squelch) wasn't working. Since that began, I have avoided everything except the trunked (mostly P25) traffic, which continues to be received correctly. Is the squelch for the problem channels using completely different squelch circuits, and, if so, does that mean I have some component failure that needs repair? I've had this radio for almost three years. Any suggestions?

This is the classic sign for the COLD SOLDER JOINT.
When receiving a analog conventional the signal bars show no signal.

Hi, Mine SDS 100 about 60 days old, was working perfect. Today got in my car and it was getting crackling and locking on channels. I adjusted squelch and still keeps chirping. Sounds same as first post here. Any ideas??

It does sound like the symptoms my radio was showing. I opened the case, but I decided not to remove the printed circuit board to begin hunting for the problem's source. So I took the easy way out and sent it to Uniden repair. They estimate they'll ship it to me by Nov. 5, but repair status indicates they haven't actually started working on it yet. Your complaint's similarity to mine makes me think it's a common enough problem that they'll be able to correct it quickly. Estimated repair cost and shipping back to me total about $89 so I included a check. If more parts than normal are needed, they'll let me know. If it only needs a circuit component or a solder joint correction, I don't imagine I'll get a partial refund, but who knows?
In my case, I was forced to manually "avoid" all channels that stopped scanning, which left me with just one P25 system to monitor. Of course, if the scanner was stopped on a static-y conventional channel and there was activity on that channel, I could hear it just fine, but that's not a workable situation.
If I find out anything useful from Uniden's repair, I'll update this thread.

Uniden treats the repairs as a flat rate. In almost all cases, the fee includes whatever parts are needed, be it a main circuit board, display, or most anything else. The exception would be a scanner that was pretty much beyond reasonable repair, like catastrophic damage from a hard fall. In those cases, they may offer a credit towards a replacement. See the note on the first page of the repair process.

Quite right. I read and re-read all the repair info before going with it. I didn't actually expect any refund for extremely simple repairs. Sorry I didn't make that clear!

Hey thanks, looks like the two month old SDS 100 has to go in for repairs. Could anyone tell me the procedure for sending it, tel #?, anything. Looked in warranty on last page of instruction book, but says its warrantied for 12 months and return address.

Set up the repair on the page Randy linked.

Since this appears to be a warrantable repair, you should include your proof of purchase to validate the warranty coverage.
