My HW100 is giving me some fits with the alignment for the first time
in the 39 years I have used it. Usually all goes just as smooth as
baby's rear. First thing I noticed is that I cannot dip the plate on
80M, close but not a dip.I decided to just start over.
The het osc setting is first of course. I am curious why the Heathkit
specs state that it is supposed to be set between -0.5VDC and -2.0VDC.
I can easily set mine between 0 and -7.4V. Why such a wide range? What
if it is set for more than -2V?
The actual problem is low power output on all bands and after a full
alignment and neutralizing the finals with a scope, I went back to
square one as mentioned above. Any ideas come to mind other than
swapping the finals? Guess maybe I should compare cathode and plate
current but that is a pain to do.
