@ SCAN SWITCH [SCAN] (p. 53)
Starts and stops a scan.
- In the VFO mode, starts and stops programmed scan.
- In the memory mode, starts and stops memory scan.
@ RIT SWITCH [RIT] (p. 32)
Turns the RIT function ON and OFF.
_ >" GB" is indicated when the function is ON.
- Use the [RIT/ ATX] control to vary the RIT frequency.
- The RIT function can be turned ON even when the
ATX function is ON.
- The RIT range is +9.999 kHz.
- The shift frequency is added to the operating fre-
quency when pushed for 2 sec.
FUNCTION
RIT (Receiver Incremental Tuning) shifts the receive
frequency up to +9.999 kHz in 1 Hz steps (or 10 Hz
steps) without shifting the transmit frequency.
This is useful for fine tuning stations which call you on an
off-frequency or when you prefer to listen to slightly
different-sounding voice characteristics, etc.
@ RIT/ATX CONTROL [RIT/A TX] (p. 32)
Shifts the receive and/or transmit frequency while
the RIT and/or 4 TX functions are ON.
- Rotate the control clockwise to increase the receive/
transmit frequency, or rotate the control counter-
clockwise to decrease the receive/transmit frequency.

@ ATX SWITCH [4TX] (p. 32)
Turns the 4 TX function ON and OFF.
- "ATX" is indicated when the function is ON.
-Use the [RIT/ATX] control to vary the ATX fre-
quency.
- The ATX function can be turned ON even when the
RIT function is ON.
- The ATX range is +9.999 kHz.
- The shift frequency is added to the operating fre-
quency when pushed for 2 sec.
FUNCTION
ATX shifts: the transmit frequency up to +9.999 kHz in
1 Hz steps (or 10 Hz steps) without shifting the receive
frequency. This is useful for simple split frequency
operation in CW, etc.
@ CLEAR SWITCH [CLEAR] (p. 32)
Clears the RIT/4 TX shift frequency.
@ AUDIO PEAK FILTER CONTROL [APF]
(inner control) (p. 30)
Varies the peak frequency of the audio peak filter
- to pick out a CW signal from interference while the
[APF] switch is ON.
- For the DSP-equipped type, turn the auto audio peak
filter OFF with [AUTO] or it will be difficult to receive
signals. It has an 80 Hz passband width. (p. 30)
