e TX/RX LED
Lights green when the squelch opens, or a signal ➥
is received.
Lights red when transmitting. ➥
r MEMORY BANK CONTROL [BANK]
❍ When both the PBT and RIT LEDs are OFF
Rotate to select a Memory bank.
❍ When the PBT LED (y) lights green
(Mode: SSB/CW/RTTY/AM)
Rotate to adjust the receiver’s IF lter passband
width using the DSP circuit.
❍ When the RIT LED (u) lights orange
Disable this control.
t M-CH CONTROL•CLEAR SWITCH [M-CH]•[CLR]
Push to select the action of the [M-CH/BANK] con-
trols as the Memory/Bank selection, PBT control or
RIT control.
❍ When the both RIT and PBT LEDs are OFF
Rotate to select a Memory channel.
❍ When the RIT LED lights orange
➥ Rotate to adjust the RIT frequency shift.
• The frequency shift range is ±9.99 kHz in 10 Hz
steps. The control tunes in 1 Hz steps when the op-
erating frequency readout is set to the 1 Hz step.
➥ Hold down for 1 second to clear the RIT shift
frequency.
✔ What is the RIT function?
The RIT (Receiver Incremental Tuning) shifts the re-
ceive 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.
❍ When the PBT LED lights green
(Mode: SSB/CW/RTTY/AM)
➥ Rotate to adjust the receiver’s IF lter pass-
band width using the DSP circuit.
➥
Hold down for 1 second to reset the PBT set-
tings.
• The PBT is adjustable in 50 Hz steps in the SSB/
CW/RTTY modes, and 200 Hz in the AM mode. At
that time, the shift value changes in 25 Hz steps in
the SSB/CW/RTTY modes, and 100 Hz in the AM
mode.
• The PBT controls function as an IF shift control.
✔ What is the PBT control?
The PBT function electronically modifies the IF pass-
band width to reject interference. This transceiver uses
the DSP circuit for the PBT function.
y PBT LED
Lights green when the [M-CH/BANK] controls act
as the PBT control.
• Push the [M-CH] switch to select PBT control.
u RIT LED
Lights orange when the RIT function is turned ➥
ON.
Lights orange when the [M-CH/BANK] ➥ controls
act as the RIT control.
• Push the [M-CH] switch to select RIT control.
• The RIT control is the inner control. The outer control
is disabled.
i RIT KEY
(p. 5-4)
Push to turn the RIT function ON or OFF. ➥
• Use the [M-CH] 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.
