1? An Eldioo FS-100 frequency standard has been pro-
cured and given a cursory evaluation by the R&D Laboratory.
It is believed that the general characteristics of this
item will be of interest to your Division.
2. The FS-100, as shown on the attached brochure, is
a transistorized, 100 kc frequency standard, powered by a
15V battery contained within the case. A 100 kc crystal is
employed for the frequency standard. According to the man-
ufacturers check points should occur each 100 ko, from 100 kc
to 30 megacycles. The F3-100 is slightly smaller than a
"King Size" cigarette package and weighs 103 grams, complete
with crystal and battery.
3. Then received the FS-100 failed to operate. In-
spection revealed a broken lead at the RF choke. After re-
pairs, the device still failed to produce detectable har-
monies at frequencies higher than 300 kc.
4. Inspection of the PS-100 indicates poor construe-
tion, especially in component mounting. Basically the prin-
ciple of operation is good. However, this unit is believed
to be unsatisfactory and unreliable.

Eldico's FS-100 is a precision, transistorized,
100KC frequency standard, smaller than a Kin(
Size package of cigarettes. The FS-100 con-
tains its own power supply and requires no
external connections.
To operate: Place switch (SW) in "on" positior
and couple output to antenna of receiver.
Accurate frequency markers at every 100KC
point (100KC to 30MC) will appear on your
receiver dial. A variable trimmer condenser
(C2) is provided for zeroing in the crystal fre-
quency against WWV. This is done by tuning
in WWV (2. 5) 5, 10, 15, 20,25 or 30MC) and
beating the output of the FS-100 against it.
Adjust condenser C2 for zero beat.
Frequency modulation of the FS-100 for identi?
fication purposes can be accomplished by sligr
pressure of the hand on the case. For clean
cw signal, the FS-100 should not be held. The
battery life is approximately shelf life of the
battery. Exact replacement can be obtained
from your local supplier or any miniature 15
volt battery of the same physical size can be
used.
