■ Frequency calibration
(approximate)
A very accurate frequency counter is required to cali-
brate the frequency of the transceiver. However, a
rough check may be performed by receiving radio
station WWV, or other standard frequency signals.
CAUTION: Your transceiver has been thor-
oughly adjusted and checked at the factory before
being shipped. You should not calibrate frequen-
cies, except for special reasons.
q Push [SSB] to select USB mode.
w Push [PBT CLR] for 1 sec. to clear the PBT set-
tings and make sure that the RIT/∂TX function is
not activated.
e Set the frequency to the standard frequency sta-
tion minus 1 kHz.
•When receiving WWV (10.000.00 MHz) as a standard
frequency, set the operating frequency for
9.999.00 MHz.
•Other standard frequencies can also be used.
r Push [EXIT/SET] several times to close a multi-
function screen, if necessary.
t Push [EXIT/SET] for 1 sec. to select the set mode
screen.
y Push [(F-5)OTHERS] to enter miscellaneous (oth-
ers) set mode.
u Push [(F-1)Y] several times to select the “Calibra-
tion marker” item.
i Rotate the tuning dial clockwise to turn the calibra-
tion marker ON.
•Side tone may be heard.
o Adjust the calibration pot on the right side panel of
the transceiver for a zero beat with the received
standard signal as shown below.
•Zero beat means that two signals are exactly the same
frequency, resulting in a single tone being emitted.
!0 Rotate the tuning dial counterclockwise to turn the
calibration marker OFF.
!1 Push [EXIT/SET] twice to exit set mode.
