And the Lecher line concept, which I told Warren about to tune his
resonant lengths for his inductor experiments.   interesting they used
Lecher lines in the old TV tuners before all the chip PLLs with those
variable capacitance diodes I cant think of the name of right now

Hector,

Where or why would one use a variometer rather than a variable coil like
an autoformer?

I see a variometer working there .... Same concept! 

thanks , there is much to see in those old designs ,,,,
