I recently got a Uniden BCD436HP. I did all of the basics. Updated database and firmware. My problem is that I am unable to pick up our local police (Duluth, MN). My Whistler 1040 picks up everything. The 436 picks up the weather channel. When I disconnect the antenna, the weather channel is gone so I believe the antenna (stock) is working ok. I went so far as to make a favorites list with just the five police frequencies. Set it to scan the list and nothing. I really want to like this radio! What could the difference be between my Whistler and the Uniden?
