I live in Flower Mound, TX. I bought a Radio Shack Triple Trunking handheld scanner about 4 years ago. Had another 1000 channel scanner but when my area started to do trunking, i had to change scanners. Worked great till about 5 days ago. It appears to be working, still scans but no noises. I can manually listen to weather and other frequencies and it works fine. I have squelch all the way down. It is just like they scanner gods changed all frequencies in my area. When i bought scanner there was a scanner guru who programmed all cities that i listen to in the Metroplex. Radio Shack closed and I lost track of him! Anyone with any ideas?
