I have never said any suppressor is a cure all, yours, mine or whatever.
So quit trying to twist words again Rich.

How did we get to parasitics again? You have got a one track mind. I am
talking about tank circuit resonances....assuming that the parasitic has
already been suppressed with your wonderful nichrome or a conventional
suppressor.
Anyway I believe that

So Rich, lots stop drifting all around the amp and stick to one area...is
that too hard to do? No parasitics to concern yourself, and a pure 50
Ohm load at the antenna port.
