'604 used 54x multiplication and DID exploit that 9th harmonic on
the osc.-rect. pair in the transmitter's 1st stage.

Case of writing w/o RTFM.

Now the tale (fable) of Link getting 1940 Armstrong-licensed SCR-293/4 
(BC-499/500) contract while Galvin fumbled with it's idea is another SWAG.  
Came from an opinion in a Radio Club of America Armstrong conference 
proceeding in '94.

Pix fm North Africa show Link FM cop sets.  I wonder if BC-499s, etc. saw
service.

P. Salati @ Fair sed he got lots of beat '499s indicating they were.

Gotta wonder.

Any help or insight appreciated

  Tnx,
