[Elecraft] Low Power on 20m and 30m

[Mike Markowski]

Hi John,

I recently had a very similar problem.  In my case, all bands were
putting out over 100 W except I could only get 90 W on 30m into a dummy
load.  I counted & recounted (& recounted!) the turns of the
corresponding toroids and double checked that I hadn't mixed up
capacitors in the those low pass filters.  Everything checked out so I
wasn't sure what to do next.  In semi-desperation I recalibrated...and
then everything checked out, all bands over 100 W.  Before trying that
you might first double check that you're getting correct output without
the 100 W stage, >= 10 W on 10/12m and >= 15 W on the rest if I recall
correctly.

Good luck!  (And please post your solution when you find it)
