Morgan,
Wow! That's a LOT of very useful information. While my situation
doesn't include an amp, I like your comment about not being able to
"kill" the Mercury III's.
*** I actually ordered one of those. Or so I thought. It seems that my
email
may not have gone through. Long story, having to do with private email
servers and reverse DNS.
I was actually on the fence. Because I've been working on a homebrew
project I call the "Medium Linear". It's a pair of MRF300's. A
wraparound cabinet from a Heathkit "Single Bander". Big heatsink in the
back with a Noctua fan. Little touch screen.
I am already thinking about the next project - a bigger linear. The
Medium Linear only does about 350W on SSB with low distortion. I'm
assured that this is about normal for a pair of MRF300's. The Bigger
Linear would use an unusual power supply - a *battery*. I have a pair
of Panasonic Lithium Ion battery packs. Each one is rated about 50V,
and can source a constant current of 100A. I would keep it topped up
with a 50V 20A supply, and should be able to do an honest kilowatt on CW
and SSB from an ordinary 125VAC socket.
