I have all the freqs in the scanner, with OPEN MODE selected, and the
scanning only stops on a few channels. When I manually go thru the
channel list, many channels are indeed active, but in scan mode, it
only stops on a few. ATT is on "Normal". I have Radio Shack 800-mhz
scanner antenna rubber duckie (just came out) installed.

could only "very strong" signals trigger the scan to stop?

side note, I installed Maha Energy PowerEx 2200 batteries, and the
scanner was turned "ON" on Tuesday at 8 PM and didnt die until
Wednesday at like midnite.
