Jeff, right, I forgot all about the K2, and I even owned a couple of them.
I never used them for operations out of a tent and from motorbike battery,
though.
I guess I should have!
Mike, the IC-703 draws 1.2A on receive at 13.8v. TERRIBLE.
But if you run it off of 9.6v, it only needs about 400mA.
Still a bit high.
Let me put current drain into perspective: try to run an entire Field Day
Contest (24 hours) off of a motorbike battery.
I have done it several times. I have always run out of power shortly before
the end of the contest. Once, using the Argonaut 509, the power ran out 30
minutes before the end of the contest. I still managed to take "First place
overall in European" in QRP class. I was operating on a mountain in
Liechtenstein (HB0). I simply rolled down the hill with the bike to start
it. If the battery had died a couple hours earlier, I surely would not have
won the contest.
100mA extra receive current is going to deplete the battery an hour or two
earlier.
It's "that" critical.

Don't forget about Icom's 703. Don't recall the current drain, but it too is
designed to operate within specs on a 9 volt battery (The r/c car battery
not the transistor battery)

A man with one clock knows what time it is. A man with two clocks is never
sure.
