I sed b4 that Link got a contract to build a slew of SCR-294s which
were a 20-28 mgc (yup, Link's term) FM.

Reason was Galvin (Moto) couldn't make xtal-controlled FM modulators
go in the SCR 508 (BC603/604)

But Link used Armstrong Phase Modulation ckt. that had been applied so
successfully at places like CT State Poh-leese.

Just read a manual from a milsurplus habitue' that says the Link
BC-499 & BC-500 exactly fit the eqpt. rack for the SCR508.

Guessed the SCR294 (Link BC-499/500) smeared egg on Galvin's face, but
didn't know it was this bad.

I speculate Galvin dint get over it & sicc'ed the Fed contract lawyers
on Link in '46.  Wasn't just the egg-on-face, it was also to shut Link
outa Poh-leese biz.

It worked, Link had to slink outa mkt.

Well we've a Link-pair here that runs ~45 mgc., not 20-28 as in SCR-294.
Exact same ckt. as BC-499/500 but loctal insteada octal tubes.  And
they're marked like  JAN-7C5, JAN 7C7, etc.  And it's 6V AND it's
not packaged for a SCR-508 wrack.

But the JAN stamps say GI buy.  So I'm guessing this set was either

   -pre SCR-294 & used in w. LA 1940 eqpt. tests

          --or--

   -for MP on-base Poh-leese cahs during ww2

CAN ANYONE CONFIRM???  I'M SURE THERE'S A GREAT STORY THERE.

May use Links outa kid's wagon on 51mgc w. a tweaked BC-1000 @ Dayton.

Everyone read the "May" word?
