RT> Hi Scott, as you were just saying about CODES....
SM> Cleveland just went to a Digital Trunked 800mhz Radio dispatch
SM> system
SM> for all 6 districts to prevent unwanted persons from gaining
SM> information they shouldn't have (mainly TV stations), S.W.A.T. and
SM> special operations units also have their own frequencies.
SM>
SM> A trunked system essentially means that you have "example" 5 different
SM> frequencies which are controlled via a central computer that rotates
SM> them when they are not in use, thereby deterring listening by persons
SM> whom may have equipment that could pick them up, and some departments
SM> have a birdie (electronic tone) which rotates on the channels not in
SM> use, making it impossible to scan the frequencies with radio traffic.
RT> No, it isn't. I can listen to my local county sheriff's office with
RT> no birdie tones even thought they are on an Ericsson system. There
RT> are also a couple of scanner commercially available that track the
RT> Motorola trunking system. Uniden has one as does radio shack.
Yes, I am aware that the "Bear Tracker" exists, but my point was most
people don't have such equipment to listen, and even then *most*
departments (brookpark/parma, oh) use digital encryption to prevent
such listening even with such equipment.
