I'm stumped with the higher bands.  40M PO is at times, stunning (factor of 100x no problem) and easy to tune. 10-20 no more than 60w from the same 5w drive and it's really hard to tune.   Swapped-out plate choke from approx. 200 to 125uH (Heathkit-sized porcelain form approx 1/2" diameter, 28 gauge).  40M worked even better but more of the same from to 10-20. Ideas, suggestions?


EDIT: Poking around testing this and that I learn that my swamping resistance is very inductive at 98H. Thought it was NI being MOX.  Apparently, I'm mistaken big time.  Far higher than all my other known NI resistors.  Search, order, wait for delivery and see, repeat. Maybe this is it, I hope so.
