I'm about to start tinkering with the rfm69hw, and was wondering if anyone has some example code? The application is to send GPS data from up to 1/3 mile away in wide-open terrain.

I'm also open to using a different chip that has a similar range (or better) if there's a lot more code examples (and it's not too pricey; I have 3 kids so I'm cheap!).

Thanks in advance for any help!
