• Effective immediately we will be deleting, without notice, any negative threads or posts that deal with the use of encryption and streaming of scanner audio.

    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.

    If you violate these guidelines your post will be deleted without notice and an infraction will be issued. We are not against discussion of this issue. You just need to do it in the right place. For example:

I'm new to DMR scanning and having a heckuva time trying to figure out systems that aren't in the Radio Reference Database.

Renaissance Hotel in Downtown Nashville has two DMR systems?
WNAT848
WPOA612

It seems that one is traditional hotel functions like maintenance, security, valet, but the second is solely event services & banquets. It sounds like WNAT848 is a DMR One Frequency (464.7750), and WPOA612 is a MotoTRBO Trunk (464.8250).

464.8250
201 - Security Encrypted​
202 - Engineering​
255 - Valet​
(oddly never heard housekeeping on radio)


464.7750
4 - Event Services (Banquets)​
Wondering if anyone else has similar experience scanning this property, as I'm not familiar enough with DMR scanning, and wondering if I'm even close to doing it right.

I have not specifically scanned for this system, likely they just has one license, and added another, and did not combine to one call sign. If you don't see the traffic rotating between the two repeaters, it is likely not a 'system' just a pair of conventional DMR repeaters. The radios may still be programmed for multiple groups, slots, channels, etc if not setup as trunking. With DMR software like DSDPlus you may be able to confirm some further details, that would indicate whether trunking like capacity plus is active, or these are conventional repeaters. If trunking with capacity plus, you would see the groups rotating between both repeaters and slots. If the groups are always on the same repeater and slot, most likely conventional. If this was not in the RR database, at this point I would submit as conventional DMR unless we find evidence of being a trunked system (i'm actually not sure, possible some DMR conventional is still submitted as a system, due to the use of multiple talk groups). Have fun, I need to put the SDS100 to better use on DMR around here, and get the DSDPlus software running again. Jeff

WNAT848 DMR Conventional.
IG - Industrial/Business Pool, Conventional
WPOA612 DMR Conventional also.
IG - Industrial/Business Pool, Conventional

So, need Color Codes, and what Slots the TG's are using .

Program as DMR One Freq in most scanners, each freq as an site, with ID Search ON. Log the Color Codes, and the Timing Slots for the TG's as you ID them.

Each Freq can have several TGs on each Slot in the system. Example: Security Exterior TG 1, slot 1, Security Interior TG 2 Slot 2, Desk Ops TG 2 Slot 1, Parking Ops TG 1 Slot 2..... And so on.

Any radio set up is a system, just this would be an 2 freq DMR conventional single site system. Which as we always do, will end up listed with a listing for EACH TG in use on EACH freq and TS.
