  1. 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.

    Nobody is stopping you from asking the tracks for it. Knock yourself out. It seems to me that the track is the one who makes that decision.

    I personally think the answer "you can't" should have just been "no". The safety of everybody out there on the track supersedes your ability to have access to the corner workers' radio frequencies so you can listen in to chatter. 

    From experience the tracks probably do not want a bunch of people calling and asking for the same information again and again, day after day. Think about the person answering your work phones, do they want to repeat some inane info four or five times a day, especially if that info is readily available for dissemination? I will almost guarantee that the track knows who is providing the marshals before the contract is signed. It is not a surprise to anyone, and given the expense of the equipment I doubt they do not know how someone can listen in. We are not the first club to ask this info. The track and the marshal contractor has no interest in shielding this infomation. 


    As far as "The safety of everybody out there on the track supersedes your ability to have access to the corner workers' radio frequencies so you can listen in to chatter. " If you are following the law and have an FCC listen then everything is public record and available anyway. Just harder to find. If Champcar, or thier duly appointed sub contractor, does not have an FCC license....that is something I would want to know and question why. I have been too busy to look. As dues paying members we should already know this info as we are paying the infastructure to make it work.


     I would also say that the ability to listen, learn about potentially deadly situaitions ahead and pass that information along  supersedes any argument you may have. How would this endanger the safety of everybody out there on the track?


    "I personally think the answer "you can't" should have just been "no"." Seriously? You are suggesting that the answer should have been a straight up no?  I beleive that  commincation over the public airways are public. Where I live, very few radio communation is encrypted. I know of no non public safety commincation that is.   Nevermind that, in the interest of appearing impartial I would give everyone access. Within the last year membership has accused Champcar of bias toward certian teams. Imagine tellling those members that they can not listen to track communicatiion. Even if no one mentions those previleged teams, the appereance should be otherwise.  If I was really interested I would question why i was told I can not listen to those communication.


    I should be even more upset if I was told a simple "no" as you suggest.

    This person is generally referred to as "control" and is supplied by the track along with the flaggers.

    A flagger will not go red flag without being instructed to by control.

    A flagger can and does go yellow before/simultaneously with calling control to explain the situation


    Usually Control and the Champcar Event Director are seated next to each other in the timing/scoring building, and thus have no radio communications link.




    Champcar does not know the frequencies used by the track at each event, particularly not in advance enough to include them in the supps.   They might in fact change during the course of the race, or maybe there will be no frequencies if the track is hard-wired for flagger coms.


    In practice the event of radio channel overlap is pretty rare.  With digital radios its even less common.  No need to make it a big deal, certainly no teams are doing this maliciously.  


    I'd say some teams dont even know their own frequencies.  I got my radios via an industrial surplus, and they have 3 channels, of which I dont know any of the frequencies.  If we try channel 1 and hear other teams, we just use channel 2.  NBD.


    As a bit of background, I was "control" (official title was Director of Event Operations) for a time trial club in the northeast for a long time, but it was many years ago. Also did some SCCA and Skip Barber stuff a long time ago. I know intimately how the corner marshal system works. Depending on the track we either supplied the corner marshals and communications, just the marshals or none of it. Most events I was both Control and Event Director. Some tracks had radios and some had hard wired systems. So I have some experience in the matter. Have never worked a corner or pit for Champcar so I was not sure how we work here. I was asking more to satisfy my curiosity.


    As the Control/Director of Event Ops I always allowed my marshals to call a red flag if appropriate. I trusted them and would rather err on the side of caution as seconds can save lives. If it was a mistake so be it, what is lost, some track time? I will take that exchange.


    I am pretty sure we always knew the tracks radio frequencies, as they did not want us to interfere with them. I definitely knew what we were operating on. A FCC license is required for most of the frequencies we use, except for the CB/FRS/MURS bands, so everyone should know what frequency they use. This includes the popular business band radios. If not you are subject to penalty. Just because it has not happened in the past does not mean it will not happen in the future. If one of us interferes with a critical infastucture commincation once the whole game may change. 


    I would almost guarantee that every track knows at least a frequency range that the contract workers use and it is available when the contract is signed, again I have some experience here.  What is the harm of asking for this information and publishing it?


    We have gotten really off topic here. The original poster was asking how to listen to race control to corner worker communication. In the end the answer is it depends on the track. If Champcar does not know or publish this information, it is probably easy to find by a Google search based off the specific track. I would also venture to guess that we could develop a database of frequencies used based off past experience. I used to have a bunch of this information but lost interest as I already listen to to a radio/scanner too much at work and need a break. 


     A dismissive "you can't" does not help answer the question.

    It's not that we don't want you too, it's that when we got setup with the new radios they were coded for us. We don't even have the ability to look at how to tell you to scan it. Plus, keep in mind, you're only listening to us talking to ChampCar staff on pit-lane. The communication toDa the corner workers if handled differently at each track, sometimes the tracks use their own radio system, sometimes they hire a contractor with radios, some tracks have a closed circuit system, each one is different and we have no ability to affect that.


    If you can figure out how to scan us on pit lane, enjoy! If Bill's idea works out, then that's great too. But it's still just pit-lane.





    Thanks for the reply. I think now there is a little bit of confusion/miscommunication going on. From everything it sounds like the new radio system is some sort of digital and not encrypted. Easy to scan with newer scanner, if the frequency is known, but I do not think we would need to listen to Champcar's radio communications.


    And I think you are right, most people do not want to listen to Champcar workers on pitlane. However, I was not aware that Champcar didn't do the corners,  which I think is what most people would want to listen to. This is where track condidtions are communicated. People want to hear ASAP where and  when there is an incident so they can pass that on to their driver. I think this is the infomation that the original poster, MichaelPal was looking for. When I used to listen, it was the corner to corner communication that I found most interesing. Most likely these are going to be the SCCA flagger channel for that area. The common ones are 151.505. 151.625, 151.700, 151.760, 158.400, and 154.5275, plus a buch more that I don't have in front of me right now. I have been to tracks that use a party telephone type system. In that case it gets a lot more difficult unless they simulcast.


    Slightly off topic but since we are here. Can you tell me who makes the decisions on track flag condition? I am assuming the head corner marshal or even an individal corner workers can call a red flag if necessary, but otherwise it would be an isolated to waving/standing yellows unless the event director called for a full course, right? Same with black flag decisions, head marshal communicates with event director and then lets corner workers know. Now, I MAY be interested in listeing to the radio link between the head marshal and event director if there was one, but I would venture to guess they do not use a radio.  Again no need to listen to Champcar as the flagger commincations would cover it all. 


    It might help to publish all of the frequencies in use for a specific event in the supps so everybody knows to stay away from those channels. I would suggest it is easier to do this than to rely on Ballenger to be there with their handy dandy radio finder to find the team and have them change channels. Make it a penalty. If they don't listen and interfere with your communications and Ballenger has to track them down, then you get X number of laps.


    Again thanks for responding, I for one greatly appreciate you taking the time to answer. 







  5. I understand ChampCar not wanting people to program a radio to listen (although you can do it as listen only) but I am curious as to why a simple scanner would not work?

    Digital isn't an issue to a newer scanner. Do you guys do go through the trouble of having encryption? Also not a problem with the right equipment and key but I would find it strange and un-necessary.


    Really just curious due to the outright dismissive "You can't" response



  6. Hard to compare NASCAR to what we do. Their oval tracks, for the most part, are much smother than most road courses. Might be because the ovals do not have big curbs. If I am still up to date on NASCAR tech, they also run a lot of coil bind suspensions, with the tire becoming the biggest spring once up to speed. 


    That allows them to run a pretty low splitter with out worrying about fluctuations in height and the resultant changes in downforce as spring rates on those tires are in the 600-900 lb range.


    Find some pictures that compare a NASCAR teams short track, restrictor plate and road course cars. They are significatntly different from one another. I am pretty sure the road course cars have a higher ride height and do not run any where near the same springs as the oval cars.

  7. Slightly off topic, but other than HPDE/SCCA stuff a long time ago I have not driven, but I have crewed a ton.

    IMSA: 4 races including Daytona, Indy, Road Atlanta and Lime Rock, plus a 24 as a spectator.


    under 12 hours:                               10 or so

    12 hours:                                          20+

    13 hours:                                          10 +/-

    24 hours:                                           5+

    Sprint races:                                    50+

    Event director for HPDE events:    50+ weekeends

    Crew for Time trials events:            20+


    I know I am missing some, but those would be minimums. There was a a year of two I spent more weekends at the track working then at home, but marriage and childrens put an end to that. 


    Thanks Matt for making me think this out.
