I was at the track today, and plenty of people (in the Premium South Stand) had large cameras.
On another note, I was able to hear several team radios with my analog scanner. I wasn’t really able to figure out which drivers they were, but I heard “box next lap” transmissions.
I think I was the only one at the track that had a radio. I had the large noise suppression headset and scanner. Security gave me alot of looks, and did a head shake and pointed like I should go get extra screening, but I just said I don’t speak Hindi, and went on my merry way. But, I was able to find the audio of the BBC TV commentary, which is on 455.35MHz. It seemed like BBC TV Control was on 455.1125MHz. Having the commentary in addition to a large screen TV across from our seats, will make for a good race day.
Without a radio, I’m not sure how anyone in the stands knows what goes on at the track. Didn’t see anyone on a phone or tablet with T&S either. Definitely can’t see the text T&S on the video feed. I guess they’re all there just to watch some race cars go past.
