Report Racecontrol channels / flagger chatter in General Discussion and ChampCar Info Posted February 22 Thank you Bill, That is helpful infomation, and now it makes sense as to why you didn't know the frequencies. Knowing this, if one was so inclined they could go the the FCC licensing page and search for Racing Radios. There it will list all the frequencies licensed to them. Guesing they probably have about 25 or so. Might take some time to sort out which frequency and it may change, but the info is out there if one was so inclined.
