Yaesu FT-101E User Manual

OPERATION
The
tuning
procedure
of
the
transceiver
is
not
complicated,
however,
care
should
be
exercised
when tuning to insure peak performance of the equip-
ment. The following paragraphs describe the procedure
for receiver and transmitter tuning.
INITIAL CHECK
Before connecting the transceiver to a power source,
carefully examine the unit for any visible damage. Check
that all modules and crystals are firmly in place and
that controls and switches are operating normally. En-
sure that voltage specification marked on rear panel
matches the supply voltage.
FREQUENCY SELECTION
The main tuning dial is color coded with the band
selector switch for proper frequency read out. When
band selected is marked in Red, the operator reads the
Red numbers on the main tuning dial. When for
example the band selected is marked in White on trans-
ceiver front panel, the operator reads the Black numbers
on main tuning dial.
The main tuning dial is marked in 25 KHz increments
between each 100 KHz segment. This provides a
course frequency setting within the band. The dial skirt
surrounding the tuning knob is marked in 1 KHz in-
crements and provides for fine settings of the trans-
ceiver operating frequency.
Following the example shown, familiarize yourself with
the relationship of main and skirt dial frequency read-
out.

CALIBRATOR wu. 100 KHz
To calibrate, set the TUNING control to the 100 KHz
point on the dial nearest the desired frequency. Tune
the preselector for maximum “S” meter deflection. Tune
the transceiyer to the 100 KHz calibrator signal for
zero beat. Two signals may be heard near the 100
KHz point. One of these is a signal feeding through
the IF stages. Always calibrate to the stronger of
these two signals. To calibrate, hold tuning knob firmly
at zero beat point and rotate skirt vernier dial to
zero position. The skirt vernier dial surrounds the
tuning knob and is held in position by a friction
locking device. This dial is easily movable by hand
but will retain its position after calibration. The trans-
ceiver must be calibrated when changing mode of opera-
tion of LSB, USB, AM or CW,
Switch the calibrator to the 25 KHz position and note
that the calibrator signal can be heard at every 25
KHz point. The calibrator switch should be in the
OFF position in normal use of the transceiver.
For bands 40-20-15-10A-10C read Black scale on main
oY dial. Setting shown in the example would then be 148
KHz plus the starting band edge frequency in MHz.
For example, on 40 meters the frequency would be
7.148 MHz. On 20 meters, 14.148 MHz, etc.
For bands 160-80-10B-10D read Red scale on main dial.
Settings shown in the example would then read 648 KHz
For example, on 80 meters the frequency would be 3.648
MHz, on 10B, 28.648 MHz, etc.
