Didn't mean to leave ya'll hangin, just didn't think there was much interest in the ol bird!
Method 1, and by far the easiest, is to install an optoscan 456 (or 456 lite) board & use it as your voice scanner with trunker. It's great using trunker to see all the traffic & pick & choose which talk group to listen to. I have a second 2006 serving as the discriminator output (what a waste, I know!) I just wish someone would come up with a "black box" APCO 25 decoder that would allow me to use this setup to hear digital signals.
The second method uses trunker, Pro-Turbo (no longer available or supported I don't think, but I have the demo version if anyone wants it.), and Bill Cheeks CE-232 add on board. It was VERY complicated to set up and was slightly slower to respond than method 1, but at the time there were no trunk trackers or they were just released and very expensive. What a thrill it was to get that configuration up & running at the time! It involved the two programs running simultaneously on one computer, and required 3 comm ports to be properly set up & running.
