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.

Analog: All but two of the NASCAR officials' channels will be utilizing which can only be monitored by a few scanners, according to the "NASCAR going digital" Radioreference Forum Thread. Still, a few NASCAR officials channels' remain analog, as listed below.
