Northside ISD Mototrbo

The listing for NISD shows the old system and, confusingly, says NXDN when they were using HT1250s. Since then, the police have switched to the Bexar County Harris system and campuses have switched to XPR7550s. Does anyone have any up-to-date info on the system?

Sorry we didn't get to this but while I was in SA yesterday, frankly it is a congested RF environment but I did notice that the LTR Passport system is still going, however there were DMR databursts being transmitted along with the 3 second LTR Passport databursts. I am a little baffled as to what the latest setup is there and would have to be parked on their system frequencies for a while to figure it out. If the campuses have in fact switched to XPR7550's, then they are definitely set up for DMR and not NXDN.

Yes, the police are apparently still using bits of the old system (noted in my ticket not in the post oops), I've seen them walking around with two radios, which looks a bit funny. However in the last couple weeks I don't recall, so that might be on its way as well. There's an older thread from 2016 with a guy who said he worked on that system, no mention of NXDN from him but same confusion over it from that OP. I'm inclined to believe NXDN on the listing is simply an error. Sorry I could not provide more details to follow up the ticket, I'm just sharing what I've observed.

I have a friend that works patrol for NISD PD. The campus officers carry two radios so they don't miss any traffic. PD radio on the campus dispatch channel on the AARRS(when they switch) for high school and middle school officers. And the other for comms with their school. Talk with APs etc....Patrol officers are on a separate channel during the school day .

They also have other district channels in their "school" radio. Transportation etc....He said some schools have left the district system(as he put it) and went their own route for radios. UHF, and UHF DMR would be my guess. I heard if you weren't near one of the towers campuses had all kinds of radio problems.
