I have used my Argosy I (analog dial) on many a Field Day on 5W, and
easily operated the entire 24 hours on batteries. I typically use a
much bigger battery than needed, such as an Optima blue-top (55AH, I think).
From memory, the 590mA RX current drain is about what I measured
too. About half of that is the panel lamps, which I disconnected.
Being incandescent, they consume about 280mA of current. Once they
are disconnected, you get a very reasonable 250-300mA current drain on RX.
