don't know if this is a radio problem or I'm too dumb to figure out Win500. I can run the scanner from Win500 (scan, manual, enter and store conventional freqs. The problem is that when I try to upload to the scanner, I get an error message that says "no response from the scanner". Also, when trying to download the conv. freqs to the computer, error message that says "Timed out recieving xxx bytes". Just like alot of people with this scanner, I'm getting redy to either pull my hair out or put the scanner through the wall
