Well, let me brag a little: My PQD5, homebrew in 1987, draws only 33mA 
on receive. And it's SSB!

It puts just 5W out, to stay in the QRP category. At home I used it with 
a 300W amplifier (using 6146 tubes), but on many backpacking trips I 
used it barefoot. It's still in perfect working order, and the amp too. 
The PQD5 is described here:
