And here are very similar licenses for the Southeastern Conference (SEC) in multiple states. Like the ACC licenses, these are also UHF, DMR, 10 watts. I'm certain it will be encrypted. Anybody know what the NFL uses?

UHF Repeaters (2w) and it is 100% ENC DMR
If they followed the Conventional plan, each team had two Freqs
a. Primary
b. Secondary if they had interference

Each Freq also had two DPL's
a. Defense
b. Offense

I would suspect the frequency plan to repeat and the Offense/Defense to be Different TG's (Speculation)

I ran DSD at the Clemson game this weekend to see if I could get any information with the new frequencies. I got information for 451.8375.
It showed 2 talkgroups being used. 5555 Slot 1 and 6666 Slot 2. DCC=6. I didn't monitor the computer while it was running. I set it up and went into the game. Looks like 6 different radio ID's show up in the event file. Just wanted to share this info.

You didn't happen to catch any of the play calls by chance, did you? Asking for a friend

 

[shajoe44]

I will listen hopefully next game.

So were these transmissions in the clear or encrypted?

I didn't monitor any of the transmissions. I just set up DSD and went into the game. Here is part of the event file.

I monitored the other frequency assigned to Clemson and here is some of the event file. Believe it or not the few moments I monitored the transmissions were in the clear. Of course, it's football lingo coming across.

It looks like they finally caught on that we can listen in

It's wild that the radio shop programmed these unencrypted.
By the way, how do the coaches headsets work? What frequencies/technology are they usually using?

 

[evan]

Using enhanced privacy at the SC-Texas A&M game.
