Default NASCAR DMR (Mototrbo) Frequencies

Has anyone found the DMR frequencies that NASCAR is using on their Mototrbo radios? For the racing events they simulcast their control channel on two analog frequencies, however, I was wondering if anyone has found and monitored their digital frequencies.

I plan on searching in two weeks when they are in Kentucky. Hopefully I will find something then unless someone can (hopefully) post them before then.

I'll be at Daytona this weekend and will try too. I was hoping that someone had a couple frequencies to get started.

Are we talking about the ones they'll use when in the garage so no one else is listening? Like during happy hour? I figured they'd be encrypted.

WQJX697 - NASCAR R & D Center

467.2125
467.2875
467.3625
467.4375
468.2625

This is DMR

Licensed at most tracks. I have twice taken a Whistler TRX-1 to Texas Motor Speedway and tried to monitor this system. But never heard a thing. Most likely the entire system is encrypted.

During the rain delay Friday night at Daytona, I searched and came across 464.8875 which came up DMR-ENC, Color Code 13 on my BCD325P2 . I also listened with my RE-3000 on the Nascar Analog 461.200 channel and this DMR keyed at the same time. I believe I found the repeater output but it's encrypted. I did come across a DMR that I believe was a Daytona Speedway hospitality radio that was unencrypted. I also scanned the NASCAR R&D frequencies and heard nothing also.

The two Repeaters 461.200 and 464.600 are the only TRBO channels that are rebroadcasted in Analog the other simplex channels all TRBO and not rebroadcasted in analog

Most of the major teams have a few private channels not listed in the freq lists. "6 private" "carx private"
was seen on the display of many of the teams trbo radios. NOT every crew member (sometimes) has a trbo radio others on the teams may only have a analog only radio. Most private teams channels are TRBO and Encrypted. Would like to use my new TRBO capable scanner and do some more listening at a track.
