Tucson is VERY hard to get. I don't know why, but radio signals don't travel far from the airport AT ALL. Every time I go up there right next to the airport, I can hardly hear them on a magmount and my Icom 207h.
Someone explained to me that there's a volcano or something under Tucson and it screws all the radio signals up. I also can never hear KDMA in Tucson.
Also, I'm having a hard time keeping the plug in the wall for some reason, so if it beeps it's just me plugging it back in.
