I heard of the ClearNode during the Handiham virtual Get on the Air camp. It connecxts to the internet through wifi and broadcasts on a UHF simplex link. You control the node with an app. It runs Linux and has open hardware. I love it. I talk to my Handiham friends, Blind Hams, and other new friends all around the world, in high quality FM voice.
Check out the ClearNode - AllStar and Echolink Node!
