Once again, thanks to everyone and their suggestions. I have tried them all, including the last one regarding Super Track, and all to no avail. Lots of frustrating parts to this mystery: I have never had a problem with reception in my home...ever, I hadn't made any changes to the radio for months prior to the problem occuring (I did update radio's software, but after the problems started), if I take my radio in the car and drive around town it works fine (in fact, I was in a small town 22 miles away last weekend and the signal was crystal clear!) The trunking "T" LED display, when reception is horrible, goes off and on like someone sending morse code, as opposed to the nice smooth rythmic pulse of the "T" when things are working fine. At this point my guess is one of two things: weather/trees or interferrence from "something". Is it possible that a cell tower that has never caused a problem before might be causing a problem now? There are a few of them around me. In fact, there is one that is within a 1/4 mile and is situated between my home and the P25 tower. But like I said, this has never been an issue.
