the emission of disturbing signals. Use the dummy load,
which is sized to dissipate about 20 watts of transmitter
power. The tuning procedure should be completed within
the least time possible from the viewpoint of the life of the
transceiver. Set the controls and knobs as shown in Table
3 below.

CW Mode
Turn BAND switch to your desired frequency (50 ~
54 MHz). After turning MODE switch to CW position, shift
STANDBY switch from REC to SEND position just to
make sure that the meter pointer deflects and ON AIR lamp
lights up, and then move back this switch to REC position.
Under this condition, move STANDBY switch to
SEND side and rotate DRIVE knob for maximum deflection

of the meter pointer deflection further. Repeat this manner
a few times.
The foregoing procedure should be carried out rapidly,
without unnecessary long delay at each step. If the tele-
graphic key device has already been connected to the
transceiver during adjustments, the device should be set in
the "key-down" condition. Having adjusted the transceiver
as above, you are now ready to use the key for CW com-
munication.
CW transmissions are automatically monitored
through the speaker of the transceiver. The audio gain of
the sidetone can be adjusted with the knob when the top lid
of the transceiver case is removed. (See Fig. 6.)
Other Modes
When the transceiver is properly adjusted for opera-
tion in CW mode, it is ready for use in other modes (FM,
LSB, USB and AM). Connect the microphone and speak
after shifting the STANDBY switch to SEND position.
Your voice will now be transmitted.
Microphone gain adjustment for FM and SSB (USB,
LSB) can be made by the gain adjusters which become
accessible when the top lid of the transceiver case is remov-
ed. The optimum setting position of these adjusters is about
the midway position of their turning range (see Fig. 6). The
microphone gain should preferably be reduced as small as
possible to assure good quality of transmission.
PTT (push-to-talk) Operation
By connecting the supplied microphone or any other
microphone equipped with PTT switch, the transceiver is
readily used for PTT operation. For communication, depress
PTT switch with STANDBY switch left in the REC position.
43. FREQUENCY CALIBRATION (Fig. 7)
To read correct frequencies, the MAIN dial must be
calibrated previously by using the 100 kHz marker unit
built in the transceiver. The marker unit is operative when
the CAL switch is set to ON. During the operation of the
marker unit, the higher harmonics can be received over the
entire band exactly at 100 kHz intervals. In this instance,
the RF input circuit (relay) is deenergized and, therefore,
external waves are scarcely received.
Frequency Calibration for USB
By rotating MAIN TUNING knob clockwise the beat
tone of the marker unit changes from high to low pitch and
