Is there some black magic required to get higher order harmonics out
of an oscillator?
I'm only trying to get 17.2Mhz out of a 3.44Mhz source and am thus far
....[snip]....

John L. Reinartz, W1QP, published "A Fundamental-Reinforced Harmonic-
Generating Circuit" in the July, 1937, issue of QST. I don't have a
copy handy, but a followup article "Putting the Harmonic Generator to
Work" in the April, 1938, QST contains this statement:

"It will be remembered that in the harmonic-generator circuit the
crystal oscillator was operated on the crystal frequency only,
and that the following tube was used to generate the even and
odd harmonics up to the 11th and 12th. For our present purpose,
the 8th harmonic is sufficient; that is, 28 Mc. from an 80-meter
crystal...."

Hope this helps.

Hey Doc. Should that quote be attributed to you or what?

Yes, at least mostly, 'Way back when email first started (with long
strings of !...!...! in the addresses), I had "Three boxes..." (altho
I don't recall just which three). Shortly thereafter, someone suggested
a fourth box and someone else the fifth, and I was lucky enough to be
able to condense all five boxes into the one line I've used ever since.

Uh, it used to be ".invalid" but until I gat this blasted new
newsreader to allow me to use that, I dunno. Maybe example.org.
Maybe a sneakemail addy I can throw away when it gets spammed to
hell so at least some people can backchannel me for the real addy if
I think they need it.

Ok. Duly noted. Maybe Myron Calhoun, et. al. ?
