$6 SPLIT SWITCH [SPLIT]
➥ Turns the split function ON and OFF when
pushed.(p. 58)
➥ Turns the quick split function ON, when pushed
for 1 sec. (p. 59)
• The offset frequency is shifted from the displayed fre-
quency.
• The quick split function can be turned OFF using set
mode. (p. 82)
➥ Turns the split function ON and sets the transmit
frequency after inputting an offset frequency with
the keypad (±4 MHz in 1 kHz steps; p. 58).
$7 PASSBAND TUNING CONTROLS [TWIN PBT]
Adjust the receiver's "passband width" of the DSP
filter. (p. 51)
• Passband width and shift frequency are displayed in the
multi-function switch indicator.
• Push [PBTC] for 1 sec. to clear the settings when not in
use.
• Variable range is set to half of the IF filter passband
width. 25 Hz steps and 50 Hz steps are available.
• These controls function as an IF shift control while in AM
mode and when the RTTY filter is turned ON. Only the
inner control may function in this case.
✔ What is the PBT control?
General PBT function electronically narrows the IF passband
width to reject interference. This transceiver uses the DSP
circuit for the PBT function.

quencies in each band.
➥ After pushing [F-INP], enter a keyed frequency.
Pushing [144 ENT] is necessary at the end.
(p. 22)
• e.g. to enter 14.195 MHz, push [F-INP] [1.8 1] [10 4]
