[Elecraft] Field Day experience with K3

[Al Lorona]

It seems to me that the solution is to improve the voltage regulation of your 
power system, rather than implicate this radio or that one for it's inability to 
follow the wide voltage swings you are experiencing. Even if Brand X "works" 
under such conditions, why would you want to, for the various reasons already 
stated? Just because my car still happens to run with 10% water in the gasoline, 
is it a good idea to continue to do so?

Yes, it might have been an inconvenience for your Field Day 2012, but I hope for 
2013 you'll have a better solution. The suggestion to reduce K3 power by 2 dB 
(1/3 of an S-unit) to 63 W is a good one which I have followed for 15 years, and 
could well solve all of your problems.

Additionally, I have used a boost regulator after the N8XJK design for almost 
ten years and now consider it indispensable. I made 300 contacts on one 35 A-h 
battery and a few more on another battery. That's pretty good efficiency.
