[Amps] Emergency communication

[Catherine James]

My K1 draws about 55 mA on receive and puts out 7 watts on transmit.  Of course it's CW only. :-)

I may get a KX2 one of these days.  We'll see.

Going back to the topic of amps, I have seen very little discussion on optimizing amps for emergency communications when little power is available.  I can run my (very inefficient) 706 Mk2G with a 35 AH battery and a 100 watt solar panel, though continuously.  If we designed something like a Class E amp for 500 watts, what would be the minimum power source needed?  Something to think about.

 The K3/K3S, designed for desktop use, draw the  most, about 1A. The KX3, designed primarily for
 backpacking, draws about  150 mA. Max out is about 10W, and there's an outboard 100W brick amp 
 that very neatly integrates with the KX3 (there's an optional tuner, controlled
 by buttons on the KX3.
