We have introduced a low power FM broadcast to help drivers and crews hear PIT PA announcements. Tune the radio in your hauler, trailer, phone or headset to the FM frequency of 91.9 FM. You'll catch our announcements as they occur. If someone wants to listen to the race call from the PA announcers upfront, you can tune into 88.5 FM during the race event. These are separate frequencies for each transmission, so you'll have to be on the frequency you want to hear the broadcast.
