My s50 at home is acting weird lately with the reception. For some reason, after I turn it on, regardless of what time of day it is, and anywhere from the first few minutes to 90 minutes, I would get the NO SIGNAL message, then randomly, it just starts working fine for the rest of the time it is turned on - could be hours and hours. Very strange, My antenna is located outside my window at home and has been untouched in the same spot for 3 years at least. In the past, once in a blue moon, i would get some reception problems, but thats it. But for the last week, this situation has happened every day. I just don't get it. Any suggestions of what I can do? I am not looking to buy new radio, just trying to fix this situation here.
