Telemetry radios from RF Design "RFD900" are 100% compatible with the 3dr radios (eg one of each can talk to each other).. but they put out a whopping 1W of power and have highly sensitive front end reciever. Perfect for FPV telemetry or other ultra range stuff. Proven to work in excess of 40 km with LOS... with omni antennas! One customer got 58km on stock antennas!
(Just a happy customer, highly recommended)
