My key down tests show I need to do considerable
work on the antenna matching situation as after ~18 minutes the double 3C86
saturates... Steve is winding up a 'super' xfmr for the VA7LF station that
we'll test here soon.
Also, I have a bolt on the antenna that is
producing a coronal discharge... That needs to be rounded off as
well...
And, I was getting complaints by Steve that I was
QRMing the waterhole 50km away...
I desided to go QRT before something or someone
blew up ;-)

Scott,
>> TIL will go into key
down mode on 137778.00Hz and will phase shift on the following sked starting
at 0100UTC. H, H+15, H+30, H+45<<
ok, all set up for
monitoring, including NPG Dixon on the lowest grabber trace. Good
luck!
>> As a side note the combined stages are far more stable
then a lone stage... The DC input current varies 1/2 as much as a lone
stage with antenna variations in the wind... I expect this to improve even
further with the 4 port combiner used for the 2KW version.<<
- a
very interesting point. Would that imply it is possible to partly absorb load
reflections in the combiners? I had always thought that you'd need a
nonreciprocal device like a circulator for that purpose - which might be sort
of bulky at LF ;-) The reduced effect on current could possibly be due to a
different phase of the reflection coefficient.
73, hope to see you
before meltdown ;-)
