PBT CLEAR SWITCH [PBT-CLR]
(p. 75)
(Mode: SSB/CW/RTTY/AM)
➥
Push to display the filter passband width and
shifting value for 1 second on the function dis-
play.
➥
Hold down for 1 second to reset the PBT set-
tings.
$5
PASSBAND TUNING CONTROLS [TWIN-PBT]
(p. 75)
(Mode: SSB/CW/RTTY/AM)
Adjusts the receiver’s IF filter passband width
using the DSP circuit.
•
Rotate this control or push [PBT-CLR] to display the
PBT settings (passband width and shifting value) for 1
second on the function display.
• Hold down [PBT-CLR] for 1 second to clear the PBT
settings.
• The PBT is adjustable in 50 Hz steps in the SSB/CW/
RTTY modes, and 200 Hz in the AM mode. In this time,
the shift value changes in 25 Hz steps in the SSB/CW/
RTTY modes, and 100 Hz in the AM mode.
• These controls function as an IF shift control.
✔
What is the PBT control?
The PBT function electronically modifies the IF passband
width to reject interference. This transceiver uses the DSP
circuit for the PBT function.

SUB DIAL SWITCH [SUB DIAL]
(p. 33)
Push to turn the SUB Dial function ON or OFF.
• “

SUB DIAL CONTROL
(outer control; p. 33)
Rotate to change the SUB Band frequency.

Decreases
The [SUB DIAL] control’s tuning Band (MAIN or
SUB) and frequency steps differ, depending on
the combination of the SUB Dial function and
SUB Band setting mode status, and the status of
the quick tuning function. See page 33 for de-
tails.
$8
MEMORY CHANNEL CONTROL [M-CH]
(inner control; p. 139)
Select a memory channel.
• Rotate clockwise to select a higher memory channel
number; rotate counterclockwise to select a lower mem
-
ory channel number.

RIT SWITCH [RIT] (p. 69)
➥
Push to turn the RIT function ON or OFF.
• Use [RIT/
∂
TX] control to vary the RIT frequency.
➥
Hold down for 1 second to add the shift frequency
of the RIT function to or subtract it from the dis-
played frequency.
✔
What is the RIT function?
The RIT (Receiver Incremental Tuning) shifts the receive
frequency without shifting the transmit frequency.
This is useful for fine tuning stations calling you off-fre-
quency or when you prefer to listen to slightly different-
sounding voice characteristics, etc.

∂
TX SWITCH [
∂
TX] (p. 81)
➥
Push to turn the
∂
TX function ON or OFF.
• Use [RIT/
∂
TX] control to vary the
∂
TX frequency.
➥
Hold down for 1 second to add the shift fre-
quency of the
∂
TX function to or subtract it from
the displayed frequency.
✔
What is the
∂
TX function?
∂
TX shifts the transmit frequency without shifting the re-
ceive frequency. This is useful for simple split frequency
operation in CW, etc.
