Hi Steve,
If you are involved in RF Data transmission I suggest you to get the book "Wireless Digital CommunicationS: Design and Theory" edited by Tucson Amateur Packet Radio Corporation, ISBN 0-9644707-2-1, you can order it directly from www.tapr.com.

I bought this book 3 years ago and is plenty of information, every time I consult it I find something new.

I think you can get Chapter Index in Tapr web page, otherwise I can scan it for you.

Best Regards.

Fran
