SUBJECT: Inspection Report No. 9 - OS-12 with
1. Project Description:
The OS-12 is a compact, stable, variable frequency oscillator.
It has a frequency range of 2 - 30 Mc without any multiplication,
spurious output of -65 db, and an accuracy of ? 1000 cps. The output
power (3.0 V peak to peak across 200 ohms) is 5.0 mw and the input
power at 12 V (? 10 percent) is 360 mw. The approximate size of the
OS-12 is 4" x 2" x 1".

c. Satisfactory technical progress: Yes
7. Project Status:
is still plagued with a problem of oscillation when in-
serting the PC board containing 68 - 69 Mc IF and mixer into the case.
Also, a problem in obtaining a sufficiently reliable loop lock-up at
the lower 10 Mc of the 2 - 30 Mc tuning range. This problem is due
to low amplitude signals from the spectrum generator in the first ten
megacycles of tuning ran e to the 68 - 69 IF amplifier and mixer where
25X1A5a1 lock-on is attained. believe that by re-
placing a now unused AGC circuit already on s last troublesome PC
board with a DC amplifier the problem will be eliminated.

There are two other areas where the OS-12 is not meeting its
original expectations. The first is power consumption. The design

goal of a $400 - $500 production cost does not look very imminent.
25X1A5a1 believes that as the OS-12 now stands production would be
around 900 to $1000 per unit in small quantities. A large contributor
to this cost would be the temperature compensation of the 152 - 180
Mc voltage controlled oscillator. The compensation tolerances are
25X1A5a1 greater than had originally thought necessary.
believes there is a way around this probably in the form of us ng
three VCO's each tunable over a 10 Mc portion of the 150 - 180 Mc
band. With the above and other considerations, I believe a lower
production cost is certainly possible.
