[R-390] 390 non A calibrator is not 200 kc

[Tom Norris]

Far be it from me to start a fight or anything, but...

In my previous post, I said the 390 non A uses a 1 mc crystal
I'm sitting here looking at the manual, and I quote -
"Calibration oscillator V901A, a Pierce Crystal oscillator
supplies a 1 mc signal for synchronizing multivibrator V902"
Not 100 kc, not 200 kc, but 1 mc. I've got two versions of the
manual here. Both say the same thing. Latest is TM 11-5820-357-35
dated 9 March 1962. The other is the "Air Force" printing
which is the same manual same date. Also have the Navy Manual.
Also says the Y2K CD.

The 390A does indeed have a 200 kc crystal oscillator in
the cal circuit. So does the 392. Got both those radios
right in front of me. Only have the manual for the 390
NON A right now. Mind you the manual and schematics may
be wrong....

Out of Lutefisk, so gotta stir up something.

[Heck, I thought I was one of the old guys, now all I did was change
my call from KA4RKT and no one recognizes me anymore... heehee]
