[TenTec] OT: Question to the group

[ka9egw at ka9egw.com]

I note that the maximum to minimum capacitance ratio of vacuum caps has it
all over air variables, and I feel that has real merit for a super wide
range link tuner of the JVM/Anneke sort, but I am afraid that particular
project will have to wait until after I win the lottery...

Paul,

Why the need for a rotating turret? Wouldn't switching taps accomplish the
same thing? Cliplead taps on the coil have been a staple of link coupled
systems since the early days of ham radio, and it seems to me that one could
locate the optimum taps for each band and then use relays to switch them. 
Doing it that way shouldn't be any more complex than a typical autotuner is.
