@2 Min (memory write) switch
Use this to memorize a frequency into a selected channel.
@® MR (memory recall) switch
Use this switch to recall a memorized frequency.

@) NB 1 (noise blanker 1) switch (R)
The noise blanker suppresses impulse noises such as
automotive ignition noise, and permits otherwise
unreadable weak signals to be received. The NB LEVEL
control (25) varies the operating level of the noise blanker.
@) NB LEVEL control (R)
This sets the noise blanker operating level. Use only the
minimum level necessary, according to operating condi-
tions and noises. Excessive N.B. level will cause distortion
or clipping.
@@ NB 2 {noise blanker 2) switch (R)
Turn on NB 2 if ''woodpecker'' radar pulse noise is the
source of interference. Note that when NB 2 operates,
signal blanking time is longer than during NB 1 operation.
The blanking ''hole'' will be apparent on the signal. This is
not a symptom of trouble. The NB 2 switch actually
operates both NB 1 and NB 2 simultaneously. It is recom-
mended that you turn this switch OFF when there is no
"*woodpecker'' noise.

@ RIT switch (R)
This controls the Receiver Incremental Tuning (RIT) circuit.
When this switch is on, the RIT indicator (13) lights.
@) RIT control (R)
This permits independently varying the receive from the
transmit frequency, up to +/—9.9 kHz, when the RIT is
on. The RIT frequency is independently displayed to the
100 Hz order.
@ RIT-CLEAR switch (R)
This resets the RIT frequency to zero offset.

FUNCTION MEMORY CH
@0 NOTCH switch (R)
This switch controls the NOTCH circuit and indicator.
61) NOTCH control (R)
Turn the NOTCH switch ON to activate the Notch filter.
Adjust the notch frequency to-null beat (carrier interfer-
ence) signals.
