Enough of that cheap one-board crap..... this amp is MODULAR!

Cool. How about a high drive portable to go behind an HF rig?
Variable input 25/100w.

The intent is to drive this from a stock CB, but if you want scale
it up then it's an easy design modification to the input module. I
can include that as an option in the design. However, know that if
FET's are used for power transistors then most of your 25/100 watt
drive would be wasted.

Are FET's the most economical transistors, or are are there other
choices for a 10 meter portable amp? The high drive would make it a
bit more legal too, wouldn't it? (dunno, just curious)

Bipolars are better for higher drive, but the more efficient setup
would be an FET amp with a low-power exciter.

Gotcha. What about the legal part of the question?

What about it?

Does the 25 watt -in- requirement make it anymore legal, or no? ( I really
don't know)
