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.

  • 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]
  • 463.2625 had group 10888888 on slot 1 (CC=15) [reported in 2015]
