Hi Nick,
I'm using a RF of Linx. I send my comunication by serial and I dont
need to do more anything.
Look this site
"http://www.linxtechnologies.com/index.php?section=products&category=rf_modules&subcategory=hp-3_series"
The speed is to 115kbps and have 8 channels of communication.
Good luck !!
Namba
