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?
