I would definately bring my scanner, last time we had the Molson INDY out here Industry Canada (IC) would assign freq's in the 451-470 band, during the Olympics here last they opened up 470-512 MHZ,I would be searching even from 406 -512 Mhz . I would suspect some digital & some analog, I regretably have never been , despite my father having been the big F1 fan, I know for these events IC, puts out a list of of the freq's they open up on their website I will take a quick look, but I am certain others would chime in as the event gets closer. I know during our INDY there was plenty to hear in the analog days , setup testing during the lead up to the event. Bon Chance as they say In Quebec.
