OPERATING INSTRUCTIONS
Section I. SETTING UP EQUIPMENT
1. AC OPERATION HOOK-UP.
a. Turn input voltage selector switch
on Power Supply RP-6 (Figure 3) to
OFF.
b. Pull sending key out of recess on
Transmitter RT-6.
c. Connect equipment as shown in
Figure 4. (Receiver crystal shown is
optional).
(1) The Jones plug marked AC must
be inserted in the OPERATE receptacle
on Power Supply RP-6 before the power
plug is connected to an AC power source
otherwise "hot" terminals will be ex-
posed and a fuse may be blown.
(2) Connect the two-prong plug of
the AC cable assembly to any AC power
source whose voltage is between 70 and
270 volts, and frequencybetween 40 and
and 400 cycles. The two-prong AC pow-
er plug can be adapted to various recep-
tacles in the following ways:
(a) Vary the spacing between the
prongs by compressing plug.
(b) Prongs can be unscrewed and
reversed to provide any combination of
small and large prongs as required to
fit various power outlets.
d. Turn input voltage selector switch
on Power Supply RP-6 clockwise to the
first position at which the neon indi-
cating light glows. The transmitter and
receiver are now ready for operation.
e. Do not turn off the equipment by
disconnecting Jones plug marked AC.
This would expose "hot" terminals.
Turn off equipment by pulling power
plug from power source.
E. Refer to Sections II 8E III of this
chapter for detailed transmitter and re-
ceiver operation.

a. By using the fundamental (fre-
: CIA-RDP78-03535A000700120003-7
quency stamped on the crystal), second
harmonic (two times fundamental), or
third harmonic (three times fundamen-
tal) of crystals of from 3 to 7 mc, the
entire frequency range (3 to 16. 5 mc)
of the transmitter can be covered.
b. DO NOT use overmode crystals,
nor operate crystals on fourth or higher
harmonics.
3. ANTENNA LENGTH & HEIGHT.
a. The length of the quarter wave
"L" antenna for a'given frequency can
be calCulated from the following for-
mulas:
L (feet) = 234
freq (megacycles)
gacycle s)
L (meters)- 0. 238 x wavelength
b. The antenna should be as high as
possible.
4. GROUND CONNECTION.
Connect the terminal marked GND to
a metal member buried in moist earth
(water pipe, gas pipe, or ground stake).
5. TUNING (Refer to Figure 8).

marked CRYSTAL. Its fundamental op-
erating frequency must be either:
(1) The same as the desired broad-
cast frequency (fundamental operation),
(2) One-half the desired broadcast
frequency (2nd harmonic operation), or
(3) One-third the desired broad-
cast frequency (3rd harmonic opera-
tion).
b. Set .the oscillator and final band-
Switches to the desired broadcast fre-
quency. Both switches must be set to
the same color.

cies from 3 to 7 mc.
( 2) Red position cover s 'frequencies
from 7 to 16.5 mc.

a. The transmitter is 'keyed:
(1) by the sending key (Figure 8),
(2) by plugging the automatic high-
speed keyer in KEY JACK (Figure 8),
. or
(3) byinserting frequency shift unit
in the crystal socket for frequency shift
operation.
b. The transmitter is ON when the
sending key is folded into the recess on
the frontpanel. The key must be in this
position for automatic keying through
the KEY JACK or for frequency shift
ope r ation.
Section III. RECEIVER RR-6
1. CONTROLS & FUNCTIONS (See
Figure 10).
a. VOLUME - Controls volume of re-
ceived signals.
b. RANGE - Selects proper frequen-
cy band.
(1) Blue position - 3 to 6. 5 mc.
(2) Red position - 6. 5 to 15 mc.
c. TUNING - Quickly sets oscillator
to any point within receiver frequency
range.
d. VERNIER TUNING. A finer: con-
trol of the large TUNING dial.
2. CALIBRATING THE TUNING DIAL
? A signal generated by a crystal-con-
trolled oscillator in the receiver offers
a means of checking the accuracy of the
frequency read on the dial. By means
of harmonics, the 500 kc crystal pro-
vides signals in 500 kc steps through-
out the dial. Thus, each megacycle
mark and each half megacycle mark be ?
come a calibration point. To calibrate
dial, proceed as follows:
a. Set RECVR-TRANS switch (Fig-
ure 9) on Filter-Accessory Unit RA-6
to RECVR.
b. Hold down button marked PRESS
TO CALIBRATE
c. Turn the BFO dial until zero is
aligned with the white mark on the hous7
ing.
d. Turn VERNIER TUNING until zero
beat is heard. NOTE: Zero beat is the
no sound point between the two sound
peaks.
e. If the indicator hairline (Figure 10)
is not exactly over a megacycle or half-
megacycle calibration point, turn AD-
JUST CALIBRATION until the hairline
coincides with the closest calibration
point.
3. TUNING (Variable)
a. Set RANGE switch (Figure 10) for
proper frequency band -"red" for high
band (6.5 to 15.mc) and "blue" for low
band (3 to 6. 5 mc). ?
b. The dial scale is calibrated di-
rectlyinmegacycles. Use the red scale

d. Calibrate dial on the nearest meg-

Turn BFO dial until zero is aligned with
the white mark on the housing before
calibrating dial. NOTE: For AM (voice)
reception, turn BFO clockwise to OFF.
e. Set dial to desired frequency and
then retune slightly, if necessary, for
best reception. ?
4. TUNING (Crystal)
a. Plug specified crystal in CRYS-
TAL CONTROL socket ( Figure 10).
NOTE: Oscillator frequency is 455 kc
higher than the received frequency.
b. Tune receiver to working frequen-
cy and proceed as above. The receiver
10
can be tuned to the fundamental, sec-
ond, and third harmonics of the crystal
if they fall within the receiver's tuning
range.
5. LOG SCALE.
a. Signals may be accurately logged
to three figures through the use of the
LOG SCALE.
(1) After station is accurately tuned
in, note the position of the white hori-
zontal line with respect to the 0, 1, 2
numerals located to the left of the dial
scale opening. These numerals repre-
sent the first digit of the log scale.
(2) Read and record the numeral
located above the white line for the first
digit. Read the other two digits on LOG
SCALE.
(3) Once a station is logged in, the
tuning dial may be re -set by these num-
