Re: Terry's remote tuning idea
How about using some sort of sliding primary tap setup, where a
remotely operated arm slides the tap along the primary winding to the
new setting, making your primary into a big variac?
you could make the outer edge of the primary cabinet rotatable. A
static arm extends inward, across the primary windings. The static
arm has a roller track on it, and mounted downward from the roller
track is the primary tap. Assuming you've carefully constructed your
primary supports so the moveable tap won't run into them, you simply
rotate the outer race with a low rpm gearmotor, and the tap should
follow the primary windings to whatever tuning position you want. But
would it interfere with primary/secondary coupling to have an arm
extending over the primary?
Or you could make the tap static, and rotate the entire primary:) that
would look cool. . . .
just runnin' the mouth.

Hi Terry, all,
I think changing tap on the primary would be the "most-desirable" way
of changing primary tune from a scientific point of view. This is
because it does not effect the power transfer process between the
rotary and the tank capacitors. I guess that changing primary tap
is just not a practical option, since contactors would have to
switch the full primary current ?
