Jerry,

I don't know if MSCS requires Raceceivers or not. As Chuck said check the MSCS website.

For a regular Lawrenceburg show radios are required. Unfortunately the frequency that we use (454.00) is not the same as USAC. If you already have a USAC radio you can have a that channel added for $20 I believe. Check with Ted Hines as he is the one who told me about it.
