[Milsurplus] BC-604 redux

[Marty R's GI-stuff haunt]

Say folks I think I've got a deal on one.  Tnx ur responses

Here's why my interest

Galvin put a squirrely saturable reactor phase modulation scheme in '604
to bypass Edwin H. Armstrong balanced modulator / phase-shift network scheme.

They didn't want to pay a license fee to EHA who was in league with Link,
Link who was already delivering the SCR-294 to "the forces."

Galvin was months late making their squirrel go (in SCR-508) & SCR-294
order upped a bunch.*  In fact per WA5CAB, all FM in North Africa was '294s.

But it seems nearly every 294 gone & no units in it's BC-500 series were ever
designated thereafter.  Odd.

Why the minitua?  AWA conference theme in 8/03 is FM.  This is a good story &
Want to scope one of those "squirrely saturable reactor" doo-dads.

* This a Galvin black-eye they maybe never got over.  It's guessed that
  they set federal gouging auditors on Link in '46 & shut him down.  So
  Motorola then had an "open field" on 2-way FM.

  Immagine Galvin's chagrin when Link turned out radios to go in SCR-508 
  mount!

  And it that's not enuf, EHA freed defense contractors fm 
  licensing in 6/42.  There's a Belmont Radio BC-603 (Galvin sub)
  here that says "licensed by EHA for military & naval use."  More
  egg-on-face.

  FM was considered one of our WW2 '3 miracles.'  A-bomb, radar, FM.

  Seems u cudn't run an AM 2-way in a tank.  Tracks made too much 
  static (qrn).  Man was talkin' while tank drivin' a HUGE leg up!!!

---and---

  Also FM capture effect enabled re-use of same freq.s over & over
  between neighboring units.

  This FM stuff covered well in US Army WW2 / Sig. Corps. / The Emergency
