There's this radio station down in Fresno I like, but the reception when it first went on the air a little over a year ago was lousy. It was like listening to old AM, with static underlining everything. When the weather was right, you couldn't get it at all. Still, I kept listening because the music selection was so awesome that I was willing to put up with the bad reception. As months went by and I listened every workday, the signal seemed to become clearer and clearer. Now it plays as clearly as any local station (except when I'm downtown surrounded by buildings). I checked the station and they haven't pumped up their signal. I'm in Modesto, California, and the weather is fairly stable. It's boring, even. I've been through all four seasons with this station in this same vehicle (I drive a delivery route for a dental lab), and when I tried recently to pull the station in on my personal vehicle's radio, it was back to square one. So, is it possible to "teach" an antenna to a signal over time? You know, have it "get used to it"? Or is there something in the atmosphere I'm forgetting?
