this did not happen all at once, reset scanner to factory settings and reprogram scanner no help.
Anyone know about the extended settings in win500 if there is any setings there that could help?
If you have noticed a degradation of VHF signals over time, then I would suspect there is a BNC module issue occurring.
For example, I know how my PSR 500 works in my immediate area. When I notice VHF degradation, it usually means one thing, the BNC module has failed. I have many posts on this subject. If, for instance, if I can no longer hear NOAA on the radio, I start saving my money for a repair trip to GRE. Typically, 800 mhz comes in fairly well, but VHF is weak and/or nonexistent.
I am very rough on my PSR 500. Sometimes, the radio gets knocked over and the rubber antenna is generally the first thing to make contact with the ground. Perhaps, it has a fulcrum effect on the circuit board, I don't know. But, diminished VHF reception is generally the first symptom of an ill radio that needs to go to the GRE hospital. I am speaking from my experience with this radio. So, I always compare baseline operation to current functioning.
I might add that I use a "hard" leather case to help cushion the inevitable fall to the floor. I wish I were less clumsy, but I'm not.
