I have a video scanner, which can receive frequencies from 20 Mhz to 3
Ghz.  I need to find the frequencies used by NASCAR for the In Car
Cameras.  I will be going to the race in Atlanta this month, and this
would make watching the race even better.  I believe these frequencies
are in the 2 Ghz range, on both the uplink to the helicopter and the
downlink to the truck, but I'm not sure.  Thanks.

Hi secret_cajunman:

Thanks for the interesting question!

Well, after some searching, I was able to find several references to
the in-car camera frequencies used by NASCAR being between 2.0 and 2.5
Ghz - with the most commonly stated value being 2.4 Ghz.

The following sites backed this up:

ESPN is apparently using 2.4 Ghz for their NASCAR racecar cameras at
PIR.

> 1 - 2/2.5 ghz "aerial camera" down freq
> 3 - 6.5/7 ghz "pit-camera" freqs

the 2.5 GHz Garbage band...

I first experienced this at a NASCAR race when the Cell Phone Company
placed a COW (Cell on Wheels) at the race and fed it via a 2.4 GHz SS
link.  The
SS link wiped out all the in-car cameras that were using Channels 8 &
9 for
downlinks.

The video goes up from the car to a repeater mounted on a  helicopter
at 3000' then back down to the truck.   All of that on 2 or 2.5 GHz.

I also found many other sites (that were not about NASCAR) selling 2.4
Ghz in-car camera systems.

I hope this is of help to you.
