[Elecraft] K2: problems with 30 and 20m filter

[Guido Tedeschi]

Hi Ron and thanks for the quick answer.
Unfortunately, on 30m the trimmers are bypassed by K3 relay, so, the
trimmers are not the "guilty"...
Waiting for a new suggestion, I will proceed with unsoldering and rebuilding
of the PA transformer T4, another "state of the art" wrong assembly made by
the original builder :-)
Ciao and thanks
Guido, ik2bcp / ab9dg

P.S. I've seen my first email repeated two times, is it the refllector or I
have some problems with my emails?
