Has anyone experianced a slow degradation of the performance of their pro-97? Mine has been picking up less and less over a 4 week period and now will hardly pick up anything at all. Tried stock ant. the RS 800mhz ant. and a thru glass car. The scanner does not perform as well as it used to with any of them. Thinking about taking it back to the shack, see if I can talkthem into an exchange, I only bought about 4 months ago and got a double length warrenty because I bought the display unit. (It was the only one they had in stock that day, but I figure this shack is slow on buisness and I imagine this unit has just sat there under that glass without being used.) Anyway just wondering if anyone had seen a prob like this so I would sound informed when I go try for replacement.
