It looks like the closest transmitters are "analog" stations either north or south of Q (within 20 miles).
Getting weak signals during the day (somewhat heavy cloud cover) would be rare. Getting a signal after dark would be easier. It looks like best shot for digital would be to point NE (up the valley) towards Kingman, or SW towards Yuma transmitters.
Jeff. Have you ever used your equipment to check for signals at night? From checking different transmitter patterns (TV Fool) it looks like you would need a bounce signal off mountains to the west of town.
You would have to admit that Q is not exactly a good customer base to waste money building low power repeaters for stations from Phoenix of Yuma areas.
