Thanks! It's just a tinker-project anyway, but I thought
it would be closer than that. Some day down the road I'd like to
work out a real model, so that I could watch things spin around
in SPICE. No practical reason to do so, but it beats stamp
collecting by a margin.
Back to your comments, I was under the impression that the Yaesu
MK-V has a pretty clean output, especially in Class-A mode. I can
tell you from experience it heats the room rather well that way,
if nothing else. :-)
