If you’ve wanted to listen in to team radio and track announcements- now you can do it yourself for about the same price as just one rental! Plus you’ll be able to do it every year afterwards at no extra cost.

Cars are entered on channels that correspond with their number. So if you see a car pulling into the pits, or watching the lead change- perhaps a crash just happened- you just type in the car number into your radio to go directly to their frequency.  All car and track frequencies are set with “Duplex off” to avoid accidentally transmitting on these frequencies.



I use CHIRP to program my Baofeng radios, and then export it to a CSV file that anyone else can use to import, or use as reference for a different programming method. You are free to use it and share with your family and friends. All driver frequencies are found on the Indy Speedway’s frequency guide, and the Official Indy 500 Spotters Guide. Additionally, I have added in frequencies that in the past have included the PA system, race officials, broadcast radio feed, and TV feeds. Some of these might not work– but they are there to experiment with. (Channels 106-127)


I’ve added the NOAA weather frequency on channel 000 for this year.

Finally- my export includes local Indianapolis repeaters and national calling frequencies for HAM operators. You must hold a Amature Radio License in order to transmit on these frequencies– but anyone can listen! (Channels 100-103) (Learn more about obtaining your HAM license here)

When choosing your radio- make sure you don’t forget your programming cable! Inputting all this work by hand will take some time, and the $20 cable is probably worth it!

In the gear section below- I have two tracks. The cheaper track is the Baofeng radios. These start at $25. But you’ll likely need that programming cable, an adapter for headphones, and of course headphones. The Uniden Bearcat BC125AT option is more expensive at $105… but it has everything you need right out of the box, except headphones. It will work with a standard 1/8″ (3.5mm) headphone jack without a special adapter. It’s also much faster at scanning, and has some great features for scanning when you don’t know all the driver frequencies. I believe the Bearcat BC125AT to be the better route to take, but the Baofengs still work well, especially for the price point.

1. gear

I have put together two options of what to buy. First is the Uniden Bearcat BC125AT – This is my new preferred method of scanning at the track. Second choice is one of the Baofeng radio options. There are more pieces you will need to buy, but this option is the cheaper overall solution.

Below both tracks are headphones and splitters and other ideas to enhance the experience, based on what you already own and might need. These options will work for both radio/scanner solutions, assuming (for the Baofeng) you have the appropriate headphone adapter.

Uniden Bearcat BC125AT Option (BEST)

  • BEST (~$105) – Uniden Bearcat Scanner (NOT a 2-way radio, uses normal 1/8″ headphone jack)
    This option includes everything in a single purchase that the three tabs on the right side offer.

Baofeng Options

(choose 1)

Adapter to make Headphones work

(Choose 1 ONLY if using Baofeng Radio)

    Programming Cable

    Extras (Will work with any set of scanners/radios)



    • (~$6) – Splitter to share one scanner with someone else
    • (~$5) – Splitter (another option)
    • (~$24) – Headphone Amp: If you’re going the ear-bud only route, you might find it isn’t loud enough when the cars are running. This amp (about the size of a deck of cards) can boost your volume higher.


    2. software

    Uniden Bearcat BC125AT Software and Drivers

    The drivers and software used to program your BC125AT can be found on the Uniden website. You will want the USB drivers and the programming software.

      Baofeng: CHIRP Programming Software

      The drivers and software used to program your Baofeng can be found on the Miklor’s website. You will want the USB drivers and the programming software. I won’t reinvent the wheel here, as Miklor has done an extreamly good job of stepping you though the driver and install on his site.
