24 Hours of Daytona

[patchman]

Looking for any frequencies used by Daytona International Speedway for track comms, IMSA and the corner workers. The Florida Region of the SCCA are used for corner workers and use UHF digital frequencies for comms.

Thanks.

To answer your question, I cross referenced your frequencies against my NASCAR database from 2023 and below are the only frequencies that were picked up in 2023.
Only discrepancy is 451.9250 DCS 047

For everyone else, I created a draft spreadsheet for IMSA. I will not be at Daytona so this is for others to confirm.

This list may be of help to you and/or others attending the Rolex 24: in the main, the frequencies used by the teams tend to be quite stable year on year: IMSA Weathertech - The RadioReference Wiki

The Euro teams freqs can be more dynamic and less predictable, this list may help for some of the teams (such as United, APR, TDS, Proton, AF Corse):

World Endurance Championship (WEC) - The RadioReference Wiki

wiki.radioreference.com

I try to keep the lists up to date so any confirmations/updates are always appreciated.

 

[racingfan360]

The analog rebroadcast for the Euro teams will be drawn from the following pool of freqs this year:
451.0750
451.8875
454.2250
454.4625
454.6625
455.1500

IMSA officials and track safety trucks (both Daytona and IMSAs) are digital and encrypted. Similar to when NASCAR is at the track. SCCA corner workers are in the clear and ALOT of radio traffic.

Can you confirm that the Fla Region SCCA are using the frequencies I listed? Thanks.

 

[The2038Problem]

Can you confirm that the Fla Region SCCA are using the frequencies I listed? Thanks.

The SCCA corner workers are using DMR 464.0125 CC10 mainly tg1 slot 1. Tg 2 on slot 2 is "channel 2" and has less traffic, mostly support/supervisors(?)

Security "channel 15" is 451.975 D516 (matches RRDB)

Security ch 2 (supervisors?) on 452.075 D23
(NASCAR 2 in RRDB)

Trams on 461.7 D423
(NASCAR 8 in RRDB)

Operations or maintenance (?) on 464.775 D423 (NASCAR 11 in RRDB)

Infield EMS is on 452.4 D662 (matches RRDB)

Capacity plus system on 452.850 does not appear to be active. IMSA officials are carrying MOTOTRBO R7s and XPR7550s. I don't really have a scanner so without digging through the fcc licenses I don't really have a way to find the new frequencies they are using for the system. Hopefully anybody else at the 24 can chime in.
