I can't help but wonder what the users of these systems are thinking? I
had a chance to monitor a bit more today, and this was mainly delivery
stuff and other things this sure came as a surprise to me as all the stuff
I have had to do with trunking has had to do with research and that has
mainly been in public safety. I know that there have bbeen some
experiments on the ham band with APCO-25. It would be interesting to
know on the 220 band how far out these systems have been heard.
