I have a PSR-500 that is deaf compared to what it was when it was new. I took the radio apart and noticed that the center wire coming from the bottom of the BNC connection had come loose from the wire going to the circuit board. I was looking through the hole from pulling the side tab up. I was able to get the wire from the circuit board back in contact with the BNC connection but it isn't rock solid, and I would like to get it soldered back right. I put it all back together and the scanner has come back alive. The problem is I don't know how to get good access in behind the silver cover, that is covering all the antenna connections and everything else. Is there a way to remove this cover to gain access, or do I need to take/send it somewhere to get it repaired? Thanks in advance for any help anyone can offer.
