HF ALE. Not terribly popular (not many people to talk with). Its the same as .mil ALE but on ham bands. Technologically what ALE can do is very impressive.

Technologically what ALE can do is very impressive. http://hflink.com/ http://hflink.com/ ALE would be HF base station type operation not hand held VHF 2M radio. Low power and SDR do not naturally go together. The folks most interested in low power drain (the trail hiker/camper types) use discrete devices as opposed to SDR. Not saying its impossible of course. I have a KX1 that draws about 30 mA when listening, so "dozens of hours" on a set of batteries. It would be challenging to find a SDR system that uses similar or less. It is challlenging enough to find a smart phone that can idle for a dozen hours on a charge much less actually do anything LOL. Still, good luck with that, etc.
