I currently have the Uniden Bearcat436hp & Whistler 1080 handheld scanners. I live on South Padre Island. I keep both units updated with firmware and database updates. Two days ago both my units have gone silent and show no signal. I've spoke to other friends who have the 436, which are new out of box and they are experiencing the same thing. Curious if changes were made to control channel 854.9125 or if the port isabel site is having a issue. Any information greatly appreciated.
