Guess it needs to run a little to figure out the systems,when I first started it was having trouble with Montclair,NJ now its working fine.Go figure.
May also have to do with where in the room you are,you could be getting a bigger signal in one part of the room,so it would decode better there.
On 700mhz this thing is very touchy,move it an inch and its night or day.
