Thanks for the responses, folks.  If anyone comes up with the team frequencies, please post them.  Scanners are pretty popular at North America races, lists of frequencies are available on the internet, and if you don't have a scanner yourself, you can usually rent one at the track.  However, I can't find frequencies for American Le Mans races, either, so something is different about sportscars.....

Newbie Le Mans guy here, wondering if anyone uses a radio scanner to pick up pit-to-driver chat during the race?  I'm aware of RLM, and have the headset radio packed, just need to know if I should bring my scanner?

TIA,

Jim
