Are you interested in portable/mobile/pedestrian mobile or emcomm operations? If you are see the RaDAR Challenge rules on the RaDAR-America Blog, setup by Marcus KD0JKM. Also look for the Google+ community Rapidly Deployable Amateur Radio (RaDAR). The community is for sharing RaDAR ideas and photos but access is not required to participate in the challenge.
Good Luck and Have Fun!

I enjoy Rapid Deployment Amateur Radio, Field Days, QRP, satellites, and CW. I have many friends in the hobby that make it fun. I will keep you posted on what I learn about amateur radio on this blog.
