I'm using WIN-500, and attempting to use the monitor/control function to record audio to my computer. I have the 'WIN500 Activity Log.txt' and 'Record Audio' boxes checked. When I click start, it creates the text activity log in the specified directory, but no .wav files are recorded. I have the programming cable connected, and the audio from the scanner to the sound card input. I hear the scanner audio fine through the computer speakers. I know it worked for me in the past, but apparently I did something then that I've forgotten to do this time. Any ideas?
