Interesting that RR has nothing on this in their database yet -

WQYD344
Atlanta Falcons Stadium Co.

462.0500
462.1000
463.6250
463.7750
464.0750
464.1125
464.1250

It's showing as a Cap+ TRBO, still working on the LCN's right now as I sit outside the stadium.

After further review, here is what the 436HP Analyze mode figured out with the Mercedes Benz Stadium System. It took me a couple of tries as I missed a couple of frequencies from the license. The scanner is tracking fine with these settings:

462.0500 - LCN 181
451.9625 - LCN 556
462.1000 - LCN 1367
463.6250 - LCN 1489
463.7750 - LCN 1501
464.0750 - LCN 1525
464.1125 - LCN 1528
464.1250 - LCN 1529
464.2875 - LCN 1542

A couple of notes:
This is showing as a DMR Tier 3 system, not CAP+ as I had previously thought.
It's not a very high-powered or is using antennas inside the building as it can be received only weakly a few blocks away.
I've only caught a few talk groups so this system is not as busy right now as it could be.
All voice channels are showing a Color Code of 1

Talk Groups:
201
218 - Engineering
220

CP here's another license you may want to investigate:

http://wireless2.fcc.gov/UlsApp/UlsSear ... ey=4100811

Looks like the NFL has gone to Bose and a company called Green-Go Digital which moved their player/coaches intercom system to VoIP using a special frequency (1870-1930 Mhz) and the digital codec assures complete encryption and privacy.

If you get bored and have a chance to scan (with your Airspy SDR) between 1870-1930 Mhz that might be interesting to see...

Here's an interesting article: https://www.geekwire.com/2017/behind-sc ... unication/

Working on those already - my work radios are on some of those frequencies...

Weird LCN’s. Any idea what brand

I think the LCNs follow a 12.5 KHz step through the entire UHF band, or something.

All Motorola as far as I can tell. Haven't spotted the model yet...
