Hi Uwe...Phew that is a relief I wasn't too happy about my diagnosis anyway,
and the linearity nullified it as an opton.
Well Done, I do like it when you solve a problem and do actually know what
caused it. I used to have a pernickity tech working with me who used to
replace the removed "faulty" component when the set worked ok, to see if the
fault returned ! He wasn't really happy until it was pinned down and set in
concrete. We used to see very few of these repaired units in the workshop
again. The ones I dont like are the ones that just "go away" and you cant
get them back. Its then either a lot of soak testing or use the customer as
the tester.
Good LF DX !!
Cheers de Alan G3NYK

Hi Jeff, hi Alan,
sri for being so late with the response.
> I use 54�H air coils
Jeff, here are two 54�H ring core coils in use. they did and do a good job
up to 1kW output.
> What is it like a lower power levels ??
Alan, it was all the same, 10W or 800W.
> what if there is insulator leakage
to find the defect I connected a aerial dummy to the end of the feeder (80m
long) in the first step: all the same! second ?accidentally- step: I
manually
moved the phasemeter somewhat ? surprise: sines like they have to be on the
screen!
I am ashamed to tell you that inside the phasemeter (homebrew) a ?naked-
wire
touched the case.
thanks for the hints and best regards
Uwe/dj8wx
