[Milsurplus] Coil-less Q multiplier ( re RU selectivity )

[Hue Miller]

A circuit is in CQ Magazine for 11-1963, page 69.
Uses a 12AT7 in a cathode coupled two terminal
oscillator circuit.  However, for remote control of
this, you would have to use a FET or such in the 
tube cathode as a remote controlled variable
resistor. Or use FETs in place of the 12AT7, thus
a 3 - FET circuit. Do-able, I think.
