The cars do have two-way radio communication. I have been able to pick up some of the cars by scanning frequencies until I hear a communication. But then you never know which car you are listening to.

The track announcer is broadcast over FM but I don't think there is a UHF/VHF frequency where you can pick up the track announcer. Race control surely has a frequency and you may be able to find the frequency for Anderson Speedway race control by doing and internet search.

Also, you might look on the Anderson Speedway website to see if they give their race control radio frequency there. While you are at the site, perhaps you could copy the entry list and paste in this thread for me.

Good luck and enjoy the race. It should be a good one if it stays dry.
