IndyCarFreq

Do you know radio frequency for USA tv broadcast of Elkhart lake race.

Updated! I was traveling, and couldn’t get to it sooner, sorry I missed it.
#26, #27 and #28 all updated this race!

Would you check Kirkwood car #27. The indycar app. has a different frequency then what I found on your page. This is for Elkhart Lake race. Thanks for all you do. Dennis

Peacock/USA at Road America was
450.1250
450.2500
450.2625
450.2875
450.3625

For any race to find the TV feeds, I search 450.0000 – 451.0000 MHz once the pre-race starts and log in my phone notes the best reception.

There are usually 5-8 frequencies in use, some have TV crew members talking over the regular TV sound. It’s easier than storing the 20 known NBC frequencies from last year and trying to remember which one worked when flipping around.

In my experience, the frequencies changes from location to location. The NBC TV feed at Indianapolis may be given by the local affiliate which may be different than Texas, Ohio, or Wisconsin.

I’m afraid that I do not. 😦
The broadcast info I’ve had in the past has been for the Indy500.

Attended Road America with my SDS100
Conor Daly got fired and was not in the 20.
IndyCar radio was 450.6875. They post their frequency on their Twitter.
451.7250 461.4250 and 456.6875 were definitely encrypted digital.

Talked to an official in the paddock, he told me their radios are now private. Only a race control public channels for race teams to monitor during the race.

Oh that’s interesting. That kinda makes sense. I had some for Indy- but I don’t know if they worked this year or not- Had a job that weekend and missed the race for the first time in… forever. 😦

Good deal.
Same with the safety team, all encrypted digital these days. I asked about it and the guy simply said “HIPPA.”

Good info, and sorry for the miss on Daly. I try to keep them as up to date as possible, and at the time, was still pulling from the spotters guide of the previous race. It is updated to Ryan Hunter-Reay going forward!

Thank you so much for this information. I just bought two Baofeng BF-F8+ radios and programmed them to operate as scanners using your file. Hopefully, there will not be too many changes before i get to Laguna Seca in September.

Just the Long Beach Frequency list today. Hope this helps someone

Awesome! Thanks for the update! Can’t wait to get out for the first practice in May in Indy!

I know that IndyCar will post updated info for each event under the Spotter Guide on their website and App.

But, wondering if anyone caught Kyle Larson’s radio during his orientation/testing sessions at Indy this year…

Which device? Baofeng/Tidradio? Or the Bearcat scanner?

How Do I program primary and secondary frequency for the same driver

I think it should. I’m a windows user, and it’s more or less if it will work with the Bearcat software. I don’t even know if they make Bearcat programming software for Mac… so as long as you can install the programming software for your machine, the config file should be good to go.

Well thanks anyway, you’re probably right about the frequency that team was on during practice…BTW - will the Bearcat config file work on a Win 10 system?

I wasn’t able to make it out there yet, and I don’t recall from past testing if those radio frequencies hold over to qualifications/race day anyways. But no- I don’t know them yet. Hope someone does- would be nice to have them on the way to the track!

Can you confirm the tones for #3 Mclaughlin, #12 Power, #28 Ericsson?
I couldn’t hear anything at the last race with these programmed.

I have an RE radio I bought about 18 years ago and still use it to this day. Uniden Bearcat SC230. Yes, frustrating to go programming it…but it still works great.

Thank you to TheMann for these updates! I check in the week before/week of the 500 and check my frequency numbers to see if updates are needed. Unfortunately I cannot just do a simple edit, have to go in and program the whole field manually again because it places the edit at the end of the line instead of staying in numerical order.

Best bet is to find a Nascar fan, and sell them the RE radio, and use the money to buy a Bearcat!

IMO, Racing Electronics scanners are useless at any event that is not NASCAR. Their current scanners cannot be computer programmed at home like the BC125AT, for example. Their scanners have proprietary connectors and the software has never been available to users. Manually programming their scanners is an exercise in frustration.

Now that NASCAR owns the company, they have no interest in supporting Indycar or NHRA.

Lame! It’s too bad they didn’t open source the over-the-air programming. I bet someone could charge $3 to $5 track-side, and push updates all day long!

We bought those damn things for simple over the air programming, not because we wanted to listen to police chatter from Mars.

No one said they were great, just easy, then the jerks bailed on us. The Trackscan scanner/people were better anyway, they got ran out more than 10 years ago.

Really??
For most radios, it just means you get “everything” - including the neighborhood kids on walkie talkies behind the race track screwing around… But nothing??

That’s poor design.

For those of us using a RE3000 the tones are essential. Without the tones I get nothing.

Appreciate it.

I did find some updated tones for those three, and have made the changes on this page as well.
#3 is DCS 223, #12 is DCS 371, and #28 is DSC 115

You can also follow that same procedure, and set the CTCSS/DCS mode to “search” – which will open it up, but flash whatever tone code it finds… so you can make note of it, and then go back and program it in, to squelch it back down. That might be your best bet, when you can’t hear a car- but want to use the features of the tones to keep out extra interference!

I wonder if/how often the tones might change. The tones are never mentioned on the official spotters guide and are listed on some pretty deep resources out there, and provided by other scanner enthusiasts out there. But- if a team is changing up the tones from track to track for various reasons, it will cause problems. And then if you don’t know how (or your radio doesn’t have an option to change or turn off tone squelch) it does kind of leave you in a limbo state.

I wonder if I should leave that information out of my lists? The frequencies almost NEVER change… and if you don’t have a tone set at all, it shouldn’t matter what the team does. You might get some extra interference, but my personal experience has been that it hasn’t been too much of a big deal.

If you are using the Bearcat BC125AT, you can go to the channel that isn’t working, Press Func + Pgm/E, Scroll down to Set CTCSS/DCS, Press Pgm/E, Scroll up to Off, Press Pgm/E, Scroll down to Exit, Press Pgm/E, and then it’s turned off, and you’ll hear everything again. Also, if you learn the correct tone while at the track, you can follow that same procedure, and set the tone in that same menu.

At gp practice and have a couple sql tone corrections that I found.

Simpson 051
Rahal 032
Robb 465

I like the squelch tones being programmed in…I’ve gotten blasted with high volume static too many times.

Good stuff!

If you’re in the area tomorrow, see if anything shows up on these frequencies. A buddy picked up hits at multiple races last year but could not confirm how they were used.

463.2875 446
462.2000 132

Same! I just got home…
I got the following updates (which are now on my page and config files…)
051 for #4 (confirmed with you- thank you!)
431 for #6
032 for #15 (confirmed with you- thank you!)
465 for #41 (confirmed with you- thank you!)
261 for #66

Thanks for the help! I love this community!

Thanks for this. Wondering why the Baofeng CSV file doesn’t include DCS codes.

Got it. Thanks.

Understandable, thanks.

If you use the tone file- and then find yourself unable to hear your driver…

Restart your radio in VFO mode. On the Baofeng UV-82, you do this by turning it off, holding down the menu key, and turning it back on.

Type in the frequency of the driver you are having issues with.

Then go to Menu, and scroll to #10, R-DCS. Press Menu again, and scroll until this is set to OFF. (Or, if someone has provided an updated TONE for you, scroll to the correct tone) Press Menu again to confirm.

Then go to menu item 27. Press the menu button to select the option, and scroll to the memory you wish to overwrite. I always select the car number. So if you’re updating Car #2, go to channel #2. Press menu to confirm. Press the exit button.

Turn off your radio.

Press and hold the menu button, and turn the radio back on to reboot in channel mode.

In theory, you should now have re-programmed that channel either with NO tone, or with the updated tone.

(and watch this page for newer versions as we get closer to the race… I update the number Indy500.TONE.24.1, Indy500.TONE.24.2, Indy500.TONE.24.3, etc… as I get more tones, or frequencies change, whatever new info I get, I put those out.)

Added a tone version to the Baofeng CSV files above, or here: https://themann00.com/wp-content/uploads/2024/05/CHIRP-Indy500.TONE_.24.4.zip

It is A LOT harder to change them in the field. If they are wrong, you’re stuck without the driver. In the past, the DCS codes have been a bit more spotty… but I’m a lot more confident this year. I don’t have them yet for the one-off drivers of the 500 that aren’t part of the regular IndyCar circuit, but might make a separate CSV file the DSC included. Would you test it out?

Bits and bobs from today
DIXON CH2 Sql is DCS606
ERICSSON CH2 Sql is DCS423

Peacock is broadcasting at 450.6875 I think you had it on channel 455 on the Bearcat file

I wish I’d been able to be at practice more this week…

CH2 meaning the backup frequency? I will update those, thank you! I think those are the ONLY confirmations I have, I’ll just clear out the rest… who knows how old they are.

I had 450.6875 is IMS PA from last year, I’ll update that to NBC though, thank you!

I’ve converted the file to go into a BC75XLT (just renamed the file) and imported it the same way. This should just work right?

Not sure how to adjust the squelch per channel… (maybe mine doesn’t do that?)

How did the Bearcat work out?

Because of problems I upgraded from my preprogrammed Racing Electronics scanner to the Uniden Bearcat BC125AT based on recommendations. New to me so appreciate the explanation about DCS, quelch tones, etc.

For the bearcat BC125AT, the squelch setting is a global setting for the whole scanner. To adjust it, press the FUNC button, then press down on the scroll wheel (vol/channel wheel on the top of the scanner next to the antenna). This should show your current squelch level, and you can set it between 0 and 15. The lower the number, the more static and interference you may hear, but the more likely you are to pickup a weak signal. I believe I keep mine around 5.

I could be wrong on this, but I am 99% sure you can not change this level on a per-channel basis.

The Tones is a specific tones squelch that is SUPER useful, as long as it is correct. These should be… as I’ve done some recent scanning, and a lot of other contributors have as well, and you can see in the other comments where some corrections and additions have been made.

Tone squelch is a way of ignoring EVERYTHING ELSE that doesn’t include that special tone. So if you know that Car #2 is always going to include a DIGITAL CODED SQUELCH of 271, you can set that tone in your scanner to say, Ignore every single incoming transmission on 464.9250, UNLESS it comes with DCS271. Then I want to hear it.

This helps keep extra chatter down from random stuff outside the track, kids and families on FRS radios, drive-thrus, people screwing around, etc. But-- if I got it wrong, or if the drivers had to change it for some reason, you won’t hear them anymore. So that is why I’ve included a section up above called BEARCAT TONE TUTORIAL - which is right below the photo of the scanner. Check that out, print it for reference, or bookmark this page. That’s a quick and easy way to get out of the tone squelch if you’re trackside, and think something might be screwy, and you can’t hear your favorite drive for some reason.

But I really do think all the tones are correct!

The actual squelch setting, I have used it for public safety before, but it’s just a general setting on the scanner for all channels.

I downloaded the tones file, not sure what it does to each channel, never heard of it before.

It might work? I don’t have the BC75XLT to test.
When you say adjust the Squelch per channel, do you mean the tones? Or the actual squelch level? (1 thru 10 setting)

Just Curious… setting up for Indy and is Graham Rahal’s secondary channel a typo? I am using the ARC software to upload to Uniden-SC230 and it doesn’t seem to like 468.8872, is that a typo or is it a correct freq?

Yeah, you bet! Hopefully my guess of 468.8875 is right… and more hopefully we won’t need it.

Fair Enough, It has been extremely rare to hear much of anything on any of the secondary frequencies in my almost 30 years of attending the 500 but you’re right something is a better chance than having nothing.
I appreciate the quick response!!

Yup- Probably supposed to be 8875
I’ve updated it to be 468.8875 - it looks like a typo from one of my resources. Could also maybe be 8870, but I think 75 is more likely.

But to be honest, I have not heard any of these secondary frequencies during testing.
The information come from a lot of resources… and I bet a lot of these resources get them from other resources as well 😉
Some of the frequencies are probably old, outdated, and may not work anymore. But I assume having something is a better chance than leaving it blank. So in the absence of good info, I’ll take the info I’ve got, and just hope it’s not needed.

After using my SC230 for many years I bought a BC125AT this year. Last year the volume knob on the SC230 literally crumbled into pieces the second I touched it, and the foam in the battery cover had been disintegrating for awhile.

I have to say you not only have the best BC125AT resource on the net, you also have the best IndyCar frequencies online as well.

I was able to test your latest frequencies (TONE) today while picking up my tickets, and was surprised how clear things were using the tones.

The place I was getting SC230 downloads from before, the month of May updates had become lackluster.
So going forward I’ll be getting them here, and you can buy Red Bull or anything else with what I used to spend elsewhere.

Yeah, they help a lot- and help protect your ears from LOUD digital garbage (most of the time)

I just discovered the tones this year. I cant tell you what a massive difference it makes to use their tones. If you dont use them you miss out on 80 % of that is going on

Thank you so much! It’s been a labor of love over the past 10+ years. I add a little bit each year, and always add something I picked up on, or something someone else pointed out. So it is certainly a community effort! Appreciate you being here, and enjoy the race!

Just set up my scanner for the 500. The guide was so helpful and easy to use! Really appreciate you putting this out for free. Just got into Indy car 2 years ago and I am so amazed by how friendly and helpful everyone is!

They are on both the tone and no-tone file.
These are local Indy area ham radio repeaters. Just something interesting to pop in and listen to while driving in and out of the track, maybe while sitting in the stands if you’re bored a few hours before the race starts. Sometimes the metal seats can get in the way… but can be interesting to hear what the locals say is going on around the area… traffic updates, etc. Nothing major. BUT… if something major does happen, you’ll hear about it on those repeaters for sure! The 146.700 will be the most active, I think.

Out of curiosity, what are the frequencies on bank 8 of the tone file? Saw those there and didn’t know if they were useful to have for the race? Keep up the Great work - you’re my absolute “go-to”.

awesome! Now you have the important job of keeping the crowd around you informed! Not all heros wear capes… But they do have scanners!

NBC 450.1625 working for Carb Day. Little bit of occasional NBC crew cross talk - lining up driver interviews, etc. Just saw that you included T-Bird channels, didn’t see that until after their flybys this afternoon but will check it out on Sunday- thanks!

Haha, I researched and added them because I saw and heard them screaming over my house!

No clue if they will work… That’s why I added so many. Threw them all at the wall, hope something sticks!

What is broadcast on Race Control 2 and Safety? I haven’t seen those in a number of years.

As for TV Production vs TV Truck, which one has the off-air commercial break discussion between the on-air people?

Thanks for the early update including tones. I’ll be using them at Long Beach and every day in May.

The truck

So, these frequencies were provided by someone scanning at St. Petersburg. So there is no guarantee that they will travel and be the same any future tracks. A lot of the multi-frequency (race control 1, race control 2) could be because they need multiple channels, or they could be fail-over channels. If one isn’t working, or has too much interference, they switch to the other. Hard to say.

For the TV stuff, I’ve found TV broadcast channels before- so you hear the commentators, and commercials, etc- and I’ve found the production comms- that’s fun! You hear the producers talking to camera guys, telling them when they are going to switch to which cameras, go zoom in on a certain car or pit, go find me a fan wearing a certain hat- that kind of stuff. It can be fun, and they also have opinions about the race going on- so that’s kind of cool inside-baseball stuff almost no one knows about. I love being a fly on that wall sometimes. It’s also very insightful during delays and red flags. They know what’s up before everyone else- because TV commercials. They have to have packages ready to go - so they know what is going on down to the minute. Want to know when the race is going to resume before everyone else, find that production back room channel.

So yeah, those were frequencies from St. Pete. Maybe they will be at the next track, maybe not- but I’ll leave them here for people to program in and try, or try adjacent!

454.000 is used by IMSA WeatherTech on weekends where they share a track with Indycar.

Nice! Thank you!!

TheMann00 - My Bearcat was a breeze to program last year at Indy just before 500 and worked great during the long day at the track due to weather - Thanks for making it so easy to program and organize.

I am not going to get to Indy this year. I believe though you had all of the NASCAR series in a similar format, they along with last years Indy freqs are still there in my scanner.

Do you have a 2025 NASCAR download as I know they change a little from yer to year…Thanks

I do not have NASCAR frequencies… but I can certainly point you in the right direction!
Here is the RadioReference forum thread about 2025 NASCAR frequencies: https://forums.radioreference.com/threads/2025-nascar-frequencies.484293/

There will be lists, and maybe even some BearCat config files there- if you don’t have an account on that site, I highly recommend one. It’s a great community, and if you ever scan and find new frequencies, we love to get that info! 😄

Thank you for publishing the Indianapolis Motor Speedway PA and Fox TV frequencies (2025 Indy 500). It is nearly impossible to find correct / current info for these two on the internet. The spotter guide provided by IndyCar does not provide them. Thank you again!!! It is really great to be able to listen to these channels during the race. Thanks again, keep up the great work. It is very much appreciated!!

No problem, and thanks to many in the community who help by passing along what they’ve scanned at the track when they can get there before I do!

Hey it’s me again.
Like I said last year, you provide more/better information on using and programming scanners than any paysite I’ve ever seen.
You also provide many more frequncy updates.
Money sent…buy yourself a case of Redbull™ and maybe some food to go with it.

eye8trogdor

Haha! Thanks man- hope all goes well with the scanner on Sunday. What scanner do you have?

I have the Uniden BC125AT, last year was my first year with it.
Have a SC230 I used for ages before that.
Had that one so long the foam in the battery compartment was crumbling.
The smaller of the knobs for volume (larger one below it was squelch) basically disintegrated when I touched it in 2023 I believe.
That was a sign from above it was time to upgrade lol.

Upgrades are fun- and usually worth it.
I just uploaded v5 of this year’s files… make sure you’ve got the latest!

During the Grand Prix on 5-10-2025 I scanned the the squelch codes for the following drivers primary frequencies as:

Pato O’ward DCS152
Christian Lundgaard DCS205
Robert Shwartzman DCS047
Callum Ilott DCS 054

AWESOME! This has been added to the page, as well as the config files!!

In the Baofeng CSV file, is there a reason that there is a RxDtcsCode of 23 on all channels?

Yeah, CHIRP defaults to something for those fields, but the key is what is in column F, “Tone”
If there is nothing there, then the tones are ignored.

What’s the difference between the multiple FOX and the IMS PA freqs. Also the spotter’s guide has 450.9000 as the freq for IMS PA. However that is not one of the freqs in either of files you provided for the bearcat.

freqs in file
IMS PA 450.4625
IMS PA 450.4375
IMS PA 450.6375

I downloaded your new file that had both tone and no tone. However, on your no tone banks (5, 6, 7, 8) you have tone set to search instead of off that you used in your original no tone files. Which is correct?

There are multiple frequencies for FOX and PA because sometimes they have backups, or maybe run them all. I’ve seen different things from different years. Sometimes a PA channel was working for me, I walk to a different part of the track and it doesn’t work anymore, but another one does. I also keep them all because they take up very little space.

Great catch on the spotter guide. I’m adding that in now- as it is being published! That hasn’t been there before, and no one else scanning provided me with the 450.9000- so either wasn’t active before, or they found PA on my existing frequencies and didn’t go hunting.

Really appreciate the note- I’ll have this updated in a moment!

Thanks so much! I enjoy getting this going every year- it’s part of my personal buildup to May! Have fun at the track this weekend!

Yes. I made this change. SEARCH is the same as OFF, where everything will get through. But when it does, it also flashes the TONE it hears in the transmission, so (if you want) you can take note of it, and update your other channels. This is how people find the tones in the first place, at least if they have this particular scanner. If you do nothing at all, but listen, it will function the same way as having TONE set to OFF.

Just wanted to send you a thanks for putting together these files for the community! Forgot to include that in my previous comment.

Sent you over some money for coffee!

Thank you for the awesome guide and setup file. This is my first year bringing a scanner to the track and you have made it so simple to understand.

I’d love to try to pick up the Thunderbirds during the flyover. Do you know of any frequencies that they might be on? I found some forums that list some common frequencies that they use at shows, but I wasn’t sure if you or anyone else had any luck picking them up at the Speedway.

Thanks again!

Will it be the thunderbirds? I can’t find anything that says it is… but maybe some fighter jets from South Dakota Air National Guard?
Just to be safe- I’ve re-published the thunderbird’s frequencies on my page, but have not added them to any of the file builds.

Jacob

I’ve turned on my BC125AT and the software erased last year’s data. I see on Step #3, you’ll be loading the frequencies so they can be simply downloaded? Is that correct? Sorry, I’m a novice.

Thank you.

Yup! Frequencies are downloadable on this page. Blue box, get the bearcat file!

I am interested in an intercom type system for me and three of my friends. Do you think it is best to use the wired method? I have also seen a video that shows two people using a Baofeng UV-5R connected to a head set and then communicate over two way radio instead of the push to talk intercom system. Also mentioned this was good to still be able to communicate when needing to get split up such as concession stand run. Looking for some help on the feasibility of this as the two way radio sounds ideal for ease of communication and not having to be tethered. Was wondering if the scanner would operate and then when the two way radio button is pressed would that interrupt the scanner audio then go back to the scanner audio once the button is released? Any help is appreciated as I learn what is best for my next trip to the track.

Yeah- so I don’t follow that series close enough to be confident that I’m providing good frequencies… but check these!

Hi TheMann00, Iam planing on going the next IMSA race was wondering if you also have Driver Frequency for IMSA or do you know where i can find them…Thanks for all your help

So, I have not used the wired intercom system out there. I have only really found one, and I link to it as an option on my page, because so many people ask… but it’s like- $350! Which is why I haven’t tried it yet.

Comms between two handhelds could work, but to remain “legal” you would want to get either a ham license, or a GMRS license. The GMRS license is a no-test, simple fee, and your license covers everyone in your home. Then you have a limited number of frequencies that you can legally use, but those handhelds would be perfect for that.

Question how do i program primary and secondary radio frequency for the same driver

i do it my hand. My scanner is an Uniden Bearcat, it’s about 30 some years old but it still works

You bet! Do you have to program by hand? Or do you have software that is helping you?

thanks for the info i have an old scanner and have 200 channels so i will try that

Depends on the radio.
If we are talking about Baofengs, they only have 128 memories. So this limits options if you are trying to get driver numbers to match the channel, where typing in channel 12 gets you over to driver 12. However, there are plenty of open channels if you don’t care about that particular feature. All you need to do is grab my existing CSV file, and change up the channel field, to give yourself more free space to add in backups.

If you have a radio that has more channels available (at least 199) you could put car 12 on channel 12, and car 12 backup on channel 112. That’s how my bearcat config is setup.

Fox TV Broadcast frequency for Elkhart Lake is 450.7500

Welcome to the new comments section! Leave feedback, update us about some frequencies, ask questions about your scanner! I’m here to help!

Hi, I have a request for the nascar frequency page, but theres no comment section for there so i came over here. Could there be a csv download button for the xfinity and trucks roster aswell? Thanks in advance

Comments are now live on https://nascarfreq.com as well!

Comments are coming soon to the NASCAR page… and those download options have been added as of this morning!

When will the frequency list come out for the NASCAR Cup, Oreily and Craftsman series?

I am working on those this week! check out https://nascarfreq.com for updates!

Updated frequencies for SPGP on the spotter guide page : https://www.indycar.com/Schedule/2026/St-Petersburg/spotter-guide

450.5375 is working for Fox booth at St. Petersburg

Hi. You are showing Next Race: Firestone Grand Prix of St. Petersburg on 3/7. Is that a copy/pasta glitch? Thanks for all that you do.

Probably just not updated yet. But it is now! 😄

Any advice on combining a file for the Indycar Nascar weekend? I assume I’d just remove the NXT banks and replace with Nascar? I’m really only interested in Indycar and the Cup series. Thanks for putting these files together, they’re very helpful for us newbies.

I have added a special double-header file available this week only!

Can you provide a CSV file with Indycar drivers, IndyNXT Drivers, and all the track/radio/tv frequencies in one file?

This is not impossible, but it breaks the primary function of many radios. The CSV was originally geared towards baofengs that only have 100 or 120 channels. So while you could put them all on one, none of the numbers would line up. Being able to switch to car 77 in a hurry would be hard… because it might be channel 32. Or channel 65 for IndyNxt. For that reason, I’ve never made one.

But…
Newer baofengs (that still need the CSV) have more channels. So I might make a second CSV file? Would that be helpful?

In the meantime, you can download all three, and then use excel or google sheets to combine them. You just have to manually change the channel numbers to what will fit your radio?

Let me know if that makes sense!

Is there an FM channel for trackside radio in Arlington? Family has FM headsets

The primary local radio affiliate in the Arlington/Dallas area for today’s Java House Grand Prix of Arlington is NewsRadio 1080 KRLD (AM)

While KRLD is the primary news/talk affiliate, 95.9 FM The Ranch is the “Official Radio Partner” for the event and is hosting live activations and “Sports Minutes” updates from the Fan Zone throughout the weekend.

I am new with the tone codes. Are they applicable to the back-up cars also?

Tones can be kind of a pain. A lot of times, they change and that change is not well documented. Tones between primary and secondary rarely match. When it doubt, don’t use them. Tones can help remove extra transmissions you don’t want to hear, but if you don’t use them, you’ll be ok!

Thank you.

Hey man, thanks for your work on the Indycar freq list. I always put them in manually, this is pretty interesting and helpful. Shoot me an email, Venmo is looking for confirmation. Thx again.

Email sent!

Thanks for compiling all this info together. Extremely helpful, and very much appreciated. If time allows can you shoot me an email. Have a question for you. Thanks again though.

Email sent!

Thank you! Added to the list!

Used all of these for the IMS GP, but none of the PA frequencies worked. Especially on qualifying weekend I like to have that, hopefully something will work.

There are lots, because it is a combo of previous years and crossing fingers that they repeat. There has never been an official release (that I’ve seen) about what frequencies to use, they way you get them for cars and IMS radio, from the spotters guide. Hopefully more are found soon by either me or other scanners at the track!

Anyone found a working PA frequency for May 2026?

450.750 was already on the bonus list, but I had it down as “Radio Primary” – I’ve changed it to “PA Primary” to reflect what we’re learning.

I have a report of maybe 450.750. I’ve added it to the list just in case!

Fox TV was 450.600 on 5/11/2026 at IMS

Thank you! - it has been added.

Good news for my fellow IMS PA system scanners. I spoke with my friend, the Indianapolis Motor Speedway’s Facility and Events Engineer. He said… “I spoke with BSI (IMS’s broadcast partner) and you should be able to hear the PS system at 450.3250.”

Great! I have added this to the list as well!

Just an FYI, I found the #31 Hunter-Reay running on his back-up channel during Carb Day.
