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.
Digital Radios:
Since 2008, NASCAR staff have been using digital MOTOTRBO TDMA digital format radios for race control and fire/medical response.
All reports indicate these MOTOTRBO channels are encrypted. Two of the MOTOTRBO frequencies are patched to the old analog channels. 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) [reported in 2015 and 2016]
- 463.2625 had group 10888888 on slot 1 (CC=15) [reported in 2015]
