I will be watching it on TV at home, but I'll have my scanner on and be monitoring the local track comms. I can hear the spotters on the roof from 5 miles away, but usually not the cars when I use a hand held inside my house.
I found the list that I bought from Racing Electronics for the Feb race to be spot on. I was in the stands on the backstretch, and using a small stub antenna and cutting on the attenuator for some channels helped.
