Note- as of the update on May 20th, Castroneves is in car #06, and Montoya is in car #6. Since I can’t have both on the same channel, I’ve moved Castroneves to #19.

Thanks!
Jacob,
Just wanted to thank you for this site and information. With Racing Electronics no longer at Indy races, this extraordinarily helpful. I purchased a Uniden 436HP last year, programmed it with BC Sentinel and took it to the race. It was fine but definitely overkill and actually more cumbersome. The 125AT looks like a much more elegant and simpler solution, especially with your config file. Thus the reason I sent you $50 yesterday. I already received from Amazon and have programmed. One question for you however, once I return home, is it best to reconfig with local files and save the Indy file for the next race? If so, where does one get local (denver, co) for the 125AT? Thank you again, Kevin
Hey Kevin, thanks so much!!
So you’re looking for local scanning options for when you return home- is that the question?
If so- there are a few good apps for finding local ham repeaters, and radioreference.com
I have an Android app called Repeater Book. It’s great, and will tell you what repeaters are near you based on GPS.
But yes- after you are done with the race, I’d pull down the file, and save it for next year. You’ll only need to update a few fields, most likely. Many frequency carry over from year to year. Some even just stay with car numbers, and you only have to change the driver name.
Does anyone actually use these frequencies to monitor at IMS? I downloaded from chirp into my radio. I was at Carb Day practice. The only frequency, which worked well was #107 the IMS Radio Network.
Other frequencies went active, but were pure static. I feel that the transmissions are encrypted and worthless, unless you have equipment to decrypt it.
I can’t speak for Carb Day, but I know the regulations require race (and qualifications) communications to be open, unencrypted. I was there on Fast 12, and heard everything. I’ve also successfully listened each race day for almost the past decade. I bet there are some/all practices where it’s up to the teams, as they may be discussing strategy and setup in realtime, and not want other teams listening in. I’m sure they’d love encryption during the race too, but thankfully that isn’t allowed!
Thanks for the great site. I was able to use my Baofeng to listen successfully on Sunday. I was wondering if anyone else had trouble with the NOAA frequency. It works fine where I live, but on Sunday I just heard a solid tone at the track when I tuned to it.
It was not working for me, or anyone in the ham community I checked in with. Luckily, we did not need it this year! Not sure what happened, but it was on the NWS side for sure.
Do you have the scanner frequency of car#16 of Simona DeSilvestro?
Does anyone have the radio frequencies for ARCA Menard West series?
