Doesn't Embedded Research make a small module like that?  I think their
stuff is now being sold by N8ET at Kanga US.

But, for those who do like rechargables, but want a full 3 watts, I have something for you. I'm working on a small switcher that will double the NiMH voltage and then linear regulate it to 12 volts. Of course this halves the effective AH rating to begin with and then chops operating time further by upping the TX current. But, I estimate operating time of >10 hours with this approach.
