Agreed. Some just can't have enough knobs and some percentage of those "must have
them turned to the right-most position".
There is also the problem of change in operating parameters when power levels are changed
without a good idea of what the effect might be.
Attenuators for QRP power levels are inexpensive and easy to build. Add a switch or relay
and they allow the exciter to run at design specifications and still have controllable output.
Using an attenuator on the input of a power booster helps insure that the impedances are
matched (maybe!) between exciter and linear amp.
HAPPY NEW YEAR!
