Found a few new TGs on ORION...

Don't know if anyone cares, but seems MAT uses 802, 803, and 804...came in handy during the freezing rain the other day...

802- busses and traffic control
803 - busses and some kind of other non bus transport
804 - seems to be MAT maintenance

Submitted to database and waiting to get more info to pin them down...

Also have seen 810 come up as one/several of the drivers accidentally hitting the emergency button...they've gotten chided by dispatch and told to 'hold the red button down for a few seconds' to clear the emergency function!

Yup...That's MAT. TG 803 is for the paratransit van service called MOBY.

TG 805 thru 809 are "tactical" talkgroups, and I haven't heard any activity on them yet. Maybe during the CWS. One of those TG's are for "Supervisory use" but I don't know which one yet.

Edit: Also, in all the time I have been monitoring the Douglas county system I have never observed the use of "I" calls, until MAT started using the system. Also, I have observed some "paging" operations in the datastream. Never seen that before, either. But I can't absolutely define if it is "paging" or "pinging".

I guess further study of the P25 trunking standard will be required.

Howdy, John!

Your comment about the observance of "paging" data in the stream might be linked to my other post relating to a possible P25 mobile data channel.
