Line 1: Line 1:
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 ([https://www.nascar.com/news-media/2013/09/14/teams-digest-rules-spanning-racing-to-radios/ source]).
 
  
The practice of car to car communication was banned in 2012 to prevent tandem drafting at the superspeedways.
 
  
'''Digital Radios:<br/>
 
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:
+
*443.250 Medical
*464.8875 CC 13 (encrypted) [reported in 2018]

*146.625 Backup
