Ha, ha! Yes, young students don't believe in much
of what us oldies try to tell them what once was. I have nothing against
American technology or opinion and use an aweful lot of it myself as it is
extremely good and some of the best in the world and I do envy you guys in
Amercia for having such a huge amount of technology and available parts and
information at your finger tips in comparison to us here in
Australia.
I have to say that I tried the suggestion of using
varicap diodes (which would have been much easier) over the old fashioned method
of a large tuning gang but the varicaps proved to be slightly noisier in their
operation and would not tune as widely which is why I have elected to go with
the tuning gang and a geared motor. What may work good for some may not work as
well for others and this is my case so I just stick to what works best for my
particular situation and after all, I am using an odd sized loop at 14 foot
circumference.
Will keep you informed as to how it
goes!
Best regards!

Michael.

Michael,
I'm thankful Australians feel so little
need to copy our technology.
When working at the Univ. of Wash. I met
far too many students who
came to learn our approach and had no respect
for their own
cultures' methods.? When I told them that in our
grandfathers' youth
we depended on such crafters as copper smiths, glass
blowers, and
potters to prototype our technology, they thought I was
lying.
Regards,
Steven

using an additional shaft geared reduction drive coupling device to
slow down the speed of turning the capacitor, choosing a lower
voltage
to drive the motor with will also slow down the turning
which will allow
more accurate tuning or peaking of the loop.
