I agree, I also think that is much of the problem
as I have said wishfully, if I could drop an amp into the middle of the
MT3000A Dentron tuner, with its ~18 position Inductance Selector and
its in/out matching... I think that this would work ... of course as
pointed out, there is a lot more to making the amp happy on all those
bands to include the soft start, yada.....
The input or transmitter tuning could be done with an inexpensive Z11
LDG tuner in line between the txcvr and the amp. big problem so far, is
doing all that tuning, bias, etc stuff I do not understand on the OUT
put side of the amp.
but yeah, with a good rotary tank coil and enough taps... that makes it
all bands capable. now, getting a kw or so thru it with suppressed
harmonics, etc... My Daiwa 801 Wattmeter is my friend hihi
where do you find a rugged, transportable 25lb legal limit amp with that
rotary tank coil with all those taps, etc???
sigh
