Along the lines of the goTenna... the Beartooth:
"Beartooth is a software defined radio peer to peer communication platform that encases your phone and doubles your battery life. Our proprietary software defined radio allows your smartphone to communicate even without cellular or wifi service. We allow for Push to Talk "PTT" voice communication, text messaging, and geolocation sharing on our offline maps."And:
"Our product will require FCC approval. We are currently working with attorneys and technical advisors who specialize in FCC approval. Our products are designed to meet the technical and legal requirements of the FCC, and we anticipate a favorable part outcome."The audio on this video is spotty and you still only get high level info, but they do mentions amateur radio as a target market (along with consumers.)
