The standard position is with the control turned fully
clockwise. As the control is turned counterclockwise,
high frequencies are cut.
@)
M.CH/VFO CH control
This control is used to select the desired memory
channel during Memory Channel Operation.
This control is also used to change the frequency in
10kHz steps during VFO operations.
The control is also used to select the desired power
on function you wish to change. See section 4-10-
15.
@ AF gain control
Turn the knob to increase or decrease the volume.
Clockwise rotation increases the volume and
counterclockwise rotation decreases the volume.
Note
The output level of the "Beep" and "Sidetone" are
not affected by adjusting of the AF gain control.
@
RF gain control
This control adjusts the gain of the receiver high-
frequency amplifier section.
For normal receiver performance, and maximum
gain, this control should be all the way to the right. If
you are having trouble copying the desired signal
make a note of the stations peak S-meter reading.
Then, adjust the RF gain control left, so that the
meter needle is stationary at this level. Now, all
signals that were less than the desired signal will be
attenuated, such as static noise, etc., making
reception easier.
If the incoming signal pegs the S-meter you can also
reduce the receiver gain by moving the RF gain
control to the left. The 8-meter pointer will always
advance up-scale as the RF gain control is moved,
to indicate that the gain has been reduced.
Simultaneous use of the RF gain control and AGC
switch
If a strong signal (such as a local station) appears in
the vicinity of the intended receive signal, the S-
meter may show unusual deflection due to the AGC
voltage developed from the strong disturbing signal.
If this occurs, move the RF gain control to the left so
the meter pointer remains at about the original
deflection peak and turn the AGC switch to the
FAST position. This will reduce the unwanted AGC
voltage and permit clear reception.
Note
This control is disabled during FM operation.
@SLOPE TUNE HIGH CUT control
Adjust the HIGH CUT control counterclockwise, and
interference from signals higher than the operating
frequency will be reduced. The high-frequency
components of the resulting receiver audio will also
be reduced.
Note
This control is disabled during FM operation.
16
®SLOPE TUNE LOW CUT control
Adjust the LOW CUT control clockwise, and
interference from signals lower than the operating
frequency will be reduced. As with the HIGH CUT
control, use of the LOW CUT control will also affect
the audio frequency passband. In this case the low
frequency components of the audio signal will be
reduced.
Note
This control is disabled during FM operation.

UP /DWN(Up/Down) switches
These switches are used to step the VFO frequency
or memory channel up and down. The frequency will
change continuously if the switches are pressed and
held.
@PTT (Push To Talk) switch
The transceiver will be placed into Transmit
whenever this switch is pressed.
