"        Firstly -- there are no longer any "Grid-Dip Oscillators" in
        practical terms.  The last one of these went out of
        style about the time John F. Kennedy was President.
        The modern incarnation of this instrument uses transistors
        (or integrated circuits).  Ergo, no "grid".   So - let us not
        mislead the gullible - I'd hate to be responsible for
        having some young'un laughed-out of the electronics shop."

	WRONG!  There are plenty of GDO's left in the world!  I
built one for 120-350 kHz last year, using a type '30 tube.....
