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.
