Dear All,
Good morning and good evening.
I'm Katsuhiko, JA3ECA, exN8EYH/Dayton OH.
I'm looking for a schematics of Hallicrafters FPM-300 MK II.
Recently, I got a transceiver, FPM-300 MK II, with the service manual.
I found however no-matching between the parts list and the schematics.
Because there is no capacitor, C134, in a schematics, although it in the
parts list of the FPM-300 MK II.
I found this capacitor, C134, had been added for the Mark II into the
original FPM-300 circuits.
I suppose that the Hallicrafters radio division in Northrop had been
under some troubles to manage the consistency of the quality control.
Because the restoration note describes the well consisted service manual
issued in 1974 by the Wilcox division of Northrop corp. group,
like pp. 3 in PDF of the following URL:
(http://www.arizona-am.net/PHOENIX/W7CPA/Hallicrafters%
20FPM-300%20Restoration%20Notes.pdf)
Does anyone have a synchronized description between the parts list and
the schematics of FPM-300 MK II?
I appreciate your associated supporting for me.
Best regards,
Katsuhiko Hirai, JA3ECA, exN8EYH/Dayton OH
