They are surrounded by hills and their radios don't have much reach, so I parked in their lot earlier. 469.950 is their maintenance frequency.
They used to run in the rain, but they had a double fatality earlier this week and they must have changed their policy. Since it rained just before I arrived, the track was closed and I wasn't able to hear their other registered frequencies. I'll head back on a better day to see if I can sort them out.
Operatives from the Vegas Area Radio Geek Alert Network's Precision Driving Unit spent some quality refresher time at SpeedVegas recently, practicing tactical scanner manipulation during high-speed precision driving for VARGAN's Scanning Vehicle Operator's Course, and discovered:
466.9625/DCS025 -- Admin type use, & SpeedVegas drivers when not on track.
468.7875/DCS032 -- Track Control -- drivers on-track +spotter/safety control.
No activity heard on the other two licensed channels during our 90 minutes there.
Radios are Motorola XPR-3500 handhelds used in analog mode & the SpeedVegas drivers wear earpieces under their helmets.
