Thanks, Don. I don't think you have to have a radio, just be a licensed ham.

I've been playing around with IRLP and AllStar Link recently. Lots of activity there. Look for the RepeaterBook app for your phone. It will show you details about all the repeaters/nodes in your vicinity. I've also just gotten on an OpenSpot2 and waiting on a FT-70DR to get on digital. From what I can tell on the OpenSpot2, there's a lot of activity there as well. Check out www.EsstCoastReflector.com (maybe .org??)
