Intermittent performance
I searched the board, but I didn't find this: My 500 only works 95% of the time. The other 5%, it does this: No reception whatsoever - not even "wx" stuff. The display reads >>>>scanning<<<< (with moving arrows), but _simultaneously_ stops on the first conventional freq and stays there with no sound. Pushing "scan" only moves the scanner ahead to the next conventional freq. Squelch, antenna, location, attenuation, power supply, V folder, on/off cycle, remove/replace batteries, physical movement - all irrelevant. I have the CPU/firmware upgrades. Then, almost magically, the scanner will start working - just because. Then, it's OK. No momentary on-again off-again behavior, it'll just work normally for days. Then...not. Any ideas?
