    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

I'm sure there is someone that is more knowledgeable about this than me. I am a college student at the University of North Carolina-Charlotte and while I was in the Belk Gymnasium, I noticed one of the employees' radios started ringing I guess something similar to I-Call on a Motorola trunked system. The employee then punched in a code on the keypad and answered the other person. The only systems listed for UNC-Charlotte are a LTR system and conventional frequencies. So, were they utilizing the LTR and if so, how can you monitor these transmissions?

LTR can't do I-call as with Moto SmartNet etc. and EDACS systems. The only way I know
to get a radio-radio call is on specific groups set up on a per-radio basis. That said:
LTR can be set up for phone interconnect i.e. phone patching, so that's probably what
is being done.

Plus of course a conventional frequency can be setup for telephone interconnect with callback to the radio from a telephone.

I have not heard if UNCC is even using LTR, though the RR DB says they have a syetem. When I worked there from '96 to '98, select employees had access to a phone patch on conventional frequencies.

Thanks for all of the replies, it must have been a phone patch then. Yea, even though the LTR system is listed, I have never captured any traffic on it either. As far as I know campus police,maintenance, housing, recreational services, and parking services are still using the conventional frequencies because I monitor them regularly.
