What is the best way to get NASCAR scanner frequency updates?

August 25, 2008   •   NASCAR How To's

I have a Radio Shack Pro-99 with the NASCAR frequencies but frequencies and car #s have changed. How do I update this with the latest information?
www.nascar.com? i don't see anything about scanner frequencies.

If you are going to any races, you can buy the frequencies for $5.
