There are a few outside the State Fair Park LTR system but the site where I found them is down at this time. You most certainly want to have the State Fair LTR system in place as well as the "color dot" frequencies since the latter are almost always in use in large venues and special events.
And i thought of something to add to CrabbyMiltion`s reply, as ya may or may not be aware, the "color dot" freqs are now the MURS (Multi-User Radio Service) now, so given the (somewhat) ease of aquiring a radio for that service, ya might be able to hear lots of stuff on those channels. I may be incorrect though, i know around here there`s little chatter on the MURS freqs, mostly a couple of late-night dudes yakking on one channel. N9NRA
I saw your car at the asa race at rockford few weeks back
gov cup kenseth and busch, pitt passes
the simplex track freqs were in use as well as the ltr used by the pd there.. The pd guy told me that they cant talk to the mile that there on dif systems..
I caught Matt Kenseth using 467.7625(he was in 3rd place)
The freq listed for Kyle Busch on midwestradiofrequencies didnt work I didnt hear kyle using that not sure what he was on or what..
Didnt listen much to anything other then matts freq while iwas watching the race. I saw that the parking guys (im? parking?) were using i beieve uhf but not sure on freq.. IDid more autgraph stuff and watching then scanning at the track.
