@Gumball928 I think you are largely getting a bum steer on this topic.
I'm still willing to bet the radios in use are analog or DMR Digital, and I bet are UHF. I'd assume small chance they are NXDN. For any of those options you CAN search and find the frequency in use. With a digital scanner like the 436 and the right dmr/nxdn options installed if required, you can decode them and find the RAN/Color Code and Talkgroup in use too. What you won't be able to do is decrypt them IF they have encryption in use. It's hard to know if they would be encrypted or not: some series do others don't, and there are good reasosn for medical related radios to have encryption.
The best research is to go and search for the frequencies in use, and also get some photos of the handheld radios actually used.
Many series have an RMC Channel (or Race Management Channel): a one way link from race control to teams, often analog but sometimes digital (and it doesn't matter if it is digital as the series often porvide the teams with a listen only radio for this link).
