The outer knob will change the
MHz portion of the standby display. At
one band-edge (118 or 136 MHz) the
following 1 MHz change will wrap
around to the other band-edge.
KX 155A and KX 165A 25 kHz Versions
The inner knob will change the kHz
portion of the standby display. It will
change in increments of 50 kHz when
the knob is pushed in and 25 kHz when
the knob is pulled out. The frequency
wrap around at the edge of the band is
also utilized when incrementing or
decrementing the kHz portion of the
standby display.
KX 165A 8.33 kHz Version
The inner knob will change the kHz
portion of the standby display. It allows
selection of 25 kHz frequencies only
when the knob is pushed in and both
8.33 kHz and 25 kHz frequencies when
the knob is pulled out. The frequency
wrap around at the edge of the band is
also utilized when incrementing or
decrementing the kHz portion of the
standby display.
To tune the radio to the desired
operating frequency, the desired frequency
must be entered into the standby
display (Figure 2) and then the
transfer button must be pushed. This
will trade the contents of the active and
standby displays (Figure 3).
NOTE: An optional remote mounted
transfer switch may also be installed in a
convenient location (such as the control
yoke) to perform the transfer operation.
The operating frequency can also
be entered by accessing the ACTIVE
ENTRY (direct tune) mode which is
done by pushing and holding the
COMM TRANSFER button for 2 or
more seconds. In the direct tune mode,
only the active part of the display is visible
(Figure 4). The desired frequency
can be directly entered into the display.
Push the COMM TRANSFER button
again to return to the active/standby
display.

The desired channel can be selected
by turning the comm kHz knob (Figure 6).
The channel frequency can be entered by
pushing the COMM TRANSFER button
which will cause the standby frequency to
flash. The comm frequency knobs are
then used to enter the desired frequency
(Figure 7). If dashes (displayed when
rotating the outer knob between 136 MHz
and 118 MHz) are entered instead of a frequency,
the corresponding channel is
skipped in channel selection mode (Figure
8). Additional channels may be programmed
by pressing the COMM TRANSFER
button and using the same procedure.
To exit the program mode and save
the channel information, momentarily push
the CHAN button. This will cause the unit
to return to the previous frequency entry
The transceiver is always tuned to the
frequency appearing in the ACTIVE display.
It is therefore possible to have two
different frequencies stored in the
ACTIVE and STANDBY displays and to
change back and forth between them at
the simple push of the transfer button.
During the transmit mode of operation,
a “T” will appear between the
ACTIVE and STANDBY displays. An “R”
will appear between the ACTIVE and
STANDBY displays if a detected signal is
strong enough to open the squelch, signifying
that the transceiver is in the receive
mode of operation.
A non-volatile memory stores the
comm ACTIVE and STANDBY frequencies
on power down. When the unit is
turned on again, the COMM ACTIVE and
STANDBY windows will display the same
ACTIVE and STANDBY frequencies that
were displayed before power down.
The KX 155A and KX 165A also have
provisions to program 32 channels.
Pressing the CHAN button for 2 or more
seconds will cause the unit to enter the
channel program mode. Upon entering
the channel program mode, “PG” is displayed
next to the channel number and
the channel number will flash indicating
that it can be programmed (Figure 5).

mode. The unit will also exit the channel
program mode if there is no button or knob
activity for 20 seconds.
The channel selection mode can then
be entered by momentarily pushing the
CHAN button (Figure 9). “CH” is displayed
next to the last used channel number.
NOTE: If no channels have been programmed,
channel 1 appears with dashes
displayed.
The comm frequency knobs can be
used to select the desired channel (Figure
