Will Close Call on my Uniden 325P2 capture transmissions or frequencies of DMR Systems if I get near the tower. One school my grand daughter attends I think changed fromNXDN to DMR but I can't locate the new frequencies.,,,TY
BCD325P2/BCD996P2: Close Call
- Thread starter RoninJoliet
- Start date
So long as it's not DMR simplex I'd say there shouldn't be an issue with the capture. Give it a shot.
Not sure what that model can and can’t do, but have you searched the school districts name on the FCC license search site?
FYI, the 325p2 works on close call on dmr simplex. Mine stops on my dmr Hotspot in my house all the time and I have to avoid it quite often
I'm not hotspot-wise, but I believe they transmit continuously and not pulsed like a subscriber does.

you have to be very close, like REALLY close.
I get Close Call hits on DMR repeaters but not on DMR simplex or DMR repeater inputs.

find a trx1 and specrtrum sweep it will pick up everything that close call cannot. Spectrum sweep picks up the signal trunk, input, simplex nxdn, dmr anything because pulsed or not it picks up the raw transmission when keyed and shows info also sweeps fast. Use it all the time instead of close call.

I tried a DMR simplex transmission from my own radio and both TRX-1 and TRX-2 sweeps past the frequency like 10 times and on the 11:th it stops and displays the DMR parameters. Transmitting analog on the same frequency detects a hit on each sweep of the frequency.

My RS 106 has the sweeper which does work better than Close Call but no digital so going to try the uniden 325 P2, thanks to everyone…The System is owned by a Company called “ABEEP” who have tons of Systems and many licenses and you can’t find the users per system…
Previous school year (22/23), the (BCIU) Berks County Intermediate school busses were using 462.0 pl100 as their main freq. Last school year (23/24) on one of the other school frequencies I heard them say BCIU switched to digital radios. I searched the FCC files; searched VHF/UHF/800/900 bands - nada. A friend of mine called me this year and said I know why you're not hearing the BCIU busses. The friend of mine knew a guy that started driving for BCIU who stopped by his house during a break and he asked him what kind of radios they were using as I was searching all over to find their freq. He showed him the new digital radio they were using:

That will be fine and dandy until a disaster happens and the cell network becomes overloaded and you get dumped.
Quite! Nothing beats a good radio backup in case of said emergencies..... (I live in earthquake & tsunami country, so.... Yeah.)

School buses isn't any critical operation, I guess. Most of our companies that used 2-way radio 20 years ago are now using apps on their mobile phones. Our police force use mobile phones 90% of the time to communicate but as mentioned they still need their 2-way radiosystem if something goes wrong with the mobile phone cellular systems as they do not have enough backup power and redundancy.
Our government authority department that operates like the FEMA in US but also procure and manage the radio systems for public safety have arranged to build apps for mobile phones to handle most of the communication needs for public safety and have a new 700MHz LTE digital radio system being installed right now to replace their Tetra system. It will pretty much operate as a mobile phone system and mostly using apps and not much voice communication, the same way it works now, but will have their own backup system and a higher redundancy also for their app operations.
