*5 DIGITAL RF SELECTOR CONTROL [DIGI-SEL]
(for MAIN band; p. 5-19)
*6 DIGITAL RF SELECTOR CONTROL [DIGI-SEL]
(for SUB band; p. 5-19)
Adjusts the digital RF selector center frequency.
• The control can be used as the audio peak filter adjust-
ment (p. 12-17)
*7 DIGITAL RF SELECTOR SWITCH [DIGI-SEL]
(for MAIN band; p. 5-19)
*8 DIGITAL RF SELECTOR SWITCH [DIGI-SEL]
(for SUB band; p. 5-19)
Turns the digital RF selector ON and OFF.
• The [DIGI-SEL] indicator lights green when the selector
is in use.
*9 MANUAL NOTCH FILTER CONTROL [NOTCH]
(for SUB band; outer control; p. 5-19)
(0 MANUAL NOTCH FILTER CONTROL [NOTCH]
(for MAIN band; outer control; p. 5-19)
Varies the peak frequency of the manual notch fil-
ter to pick out a receive signal from interference
while the manual notch function is ON.
• Notch filter center frequency:
SSB : –1060 Hz to 4040 Hz
CW : CW pitch freq. + 2540 Hz to CW pitch freq.
–2540 Hz
AM : –5100 Hz to 5100 Hz
(1 CW PITCH CONTROL [CW PITCH] (p. 4-5)
Shifts the received CW audio pitch and monitored
CW audio pitch without changing the operating fre-
quency.
(2 RIT SWITCH [RIT] (p. 5-10)
➥ Turns the RIT function ON and OFF when
pushed.
• Use [RIT/∂TX] control to vary the RIT frequency.
➥ Adds the RIT shift frequency to the operating fre-
quency when pushed for 1 sec.
✔ What is the RIT function?
The RIT (Receiver Incremental Tuning) shifts the receive fre-
quency without shifting the transmit frequency.
This is useful for fine tuning stations calling you on an off-fre-
quency or when you prefer to listen to slightly different-
sounding voice characteristics, etc.
(3
∂
TX SWITCH [
∂
TX] (p. 6-4)
➥ Turns the ∂TX function ON and OFF when
pushed.
• Use [RIT/∂TX] control to vary the ∂TX frequency.
➥ Adds the ∂TX shift frequency to the operating
frequency when pushed for 1 sec.
✔ What is the
∂
TX function?
The ∂TX shifts the transmit frequency without shifting the re-
ceive frequency. This is useful for simple split frequency op-
eration in CW, etc.
(4 CLEAR SWITCH [CLEAR] (pgs. 5-10, 6-4)
Clears the RIT/∂TX shift frequency when pushed
for 1 sec. or when pushed momentarily, depending
on the quick RIT/∂TX clear function setting
(p. 12-
17)
.
(5 QUICK TUNING SWITCH [TS] (for MAIN band)
(6 QUICK TUNING SWITCH [TS] (for SUB band)
➥ Turns the quick tuning step ON and OFF. (p. 3-
6)
• While the quick tuning indicator, “Z,” is displayed
above the frequency indication, the frequency can be
changed in programmed kHz steps.
• 0.1, 1, 5, 9, 10, 12.5, 20 and 25 kHz steps are avail-
able for each operating mode independently.
➥ When the quick tuning step is OFF, push for
1 sec. to turn the 1 Hz tuning step ON and OFF.
(p. 3-7)
➥ When the quick tuning step is ON, push for
1 sec. to enter quick tuning step set mode. (p. 3-
6)
(7 SPEECH SWITCH [SPEECH]
(for MAIN band; p. 13-3)
(8 SPEECH SWITCH [SPEECH]
(for SUB band; p. 13-3)
➥ Push to announce the S-meter indication and the
selected readout frequency.
➥ The selected operating mode is additionally an-
nounced when pushed for 1 sec.
