Scott and Friends,
The ammeter check results are in....
Dead Meter.
I went over the antenna connections cleaning and soldering
and a small
amount of retuning was required.
Someone asked how
things are set up now...
There are two coil forms involved. On
the first is a bifilar winding with
ten turns each for the coaxial feed
and for the antenna feed. One end of
each of these windings is
grounded.
The second form has the loading inductor for the
antenna. It consists of a
single layer close wound solenoid with 40
turns of ~16 Formvar coated wire
two inches long and 10-3/4 inches in
diameter. The entire coil exactly
resonates the antenna, without
taps and without using the Variometer.
It is a very simple and
straightforward setup. The fact that there should
be a lower antenna
resistance bothers me, but NOT enough to play with it.
That antenna
plays. I may make up an antenna current meter from the LF
Today
book. What cuts the toroid core material and leaves a sooth cut or am
I dreaming?
