Gee, thanks. I was debating with myself whether this was a worthy event to post or not. I decided that even if it turned out to be nothing, there was a LOT of stuff going on and that makes for good hearing.
I hear people connecting their scanners to their PCs for a lot of reasons such as hearing digital broadcasts and decoding digital data. All you need to do is connect the headphone output to your PC or MP3 recorder and you can have that audio buffering you want. I realize in that case it would be w/o the channel info, and you would not be able to lock onto one channel, but perhaps you'd hear enough to know what happened. My scanner was so locked on the channel before I locked it there manually I could not help but hear the action. Then I locked it on SO 3 and turned on another scanner to hear regular traffic. Some of that regular traffic was for the same event, but on other channels.
Have a great day,
George
