I have a six month old GRE 600 scanner, and it has intermittently cut out since it was new. It will lose audio for about 1 second, no matter how strong or weak of a signal. It does this every 10 to 15 seconds when someone is talking. the loss is not too objectionable, but it is annoying. I expect a little more of a $500 scanner. Has anyone noticed this happening on their scanner? Any ideas? It makes understanding what is going on when you miss part of the conversation.
