Steve:
A modified NN1G draws only 7 ma. See the articles in "QRP Power" by
ARRL on the modifications. They mainly involve using low power
regulators (a 78L08 draws 4ma of bias current, no load), a lower power
op-amp for the audio, and changes to the T/R circuit.
I built a modified version of this for the 80m sprint.
I think a regular NN1G draws about 14 ma. In comparison, a Sierra
type receiver or a Norcal 40a draws about 45ma.
