For some reason, my new PSR-300 recieves very poorly. I put 3 different antennas on it, and still recieves very poorly. It usually starts off recieving fine once you turn it on, then as soon as I leave the house it gets very poor. I can best the describe the recpetion is very "cracky" and hit and miss, and eventually cannot recieve anything at all. I bought it online at scanner master, but my dumb self threw out all the boxes and paperwork that came with it so returning it is not an option. I am trying to mainly monitor the Sacramento Public Safety trunked system. I listen to my Uniden base station to compare it and the base station recieves fine. So what am I doing wrong? Did I just get a lemon?
