All race communications between car, spotter and driver are analog in the clear. In fact, since 2013 NASCAR has banned all digital radio usage by teams during races (source).
The practice of car to car communication was banned in 2012 to prevent tandem drafting at the superspeedways.
All reports indicate these MOTOTRBO channels are encrypted. Radioreference listeners have reported the following in use at multiple NASCAR events:
- 464.8875 (CC=13) (encrypted) [reported in 2018]
- 463.6250 had group 15735975 on slot 1 and 15642315 on slot 2 (CC=11) (encrypted) [reported in 2015 and 2016]
- 463.2625 had group 10888888 on slot 1 (CC=15) (encrypted) [reported in 2015]
Two of the MOTOTRBO frequencies are patched to the old analog channels for fans and NASCAR teams to monitor.
- 461.200 432 DPL - NASCAR Race Control*
- 464.600 631 DPL - NASCAR Race Control*
*Confirmed May 2019 (source)
