COMM Transceiver

Rotate the VOL knob clockwise
from the OFF position. Pull the VOL
knob out and adjust for desired listen-
ing level. Push the VOL knob back in
to actuate the automatic squelch.
The left portion of the digital display
readout is allocated for COMM ACTIVE
and COMM STANDBY frequencies with
a "T" between them to indicate TRANS-
MIT and an "R" to indicate RECEIVE
modes of operation.
Select the desired operating fre-
quency in the standby display by rotat-
ing the Frequency Select Knobs either
clockwise or counterclockwise. A clock-
wise rotation will increment the previ-
ous frequency while a counterclockwise
rotation will decrement the previous fre-
quency.
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 fre-
quency must be entered into the stand-
by 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 dis-
play is visible (Figure 4). The desired
frequency can be directly entered into
the display. Push the COMM TRANS-
FER button again to return to the
active/standby display.
