What is the PBT control?
PBT electronically narrows the IF passband width to reject
interference. This transceiver uses DSP to implement PBT.
➥While M-ch/RIT is selected:
●
●
Rotate the inner control to select a memory
channel number (p. 102).
●
●
Push inner control for 1 sec. to turn the
RIT/∂TX mode ON (pgs. 75, 88).
•Push[
Z
(
MENU
/
GRP
)] to exit the RIT/∂TX mode.
●
●
While the RIT/∂TX mode is OFF:
Rotates outer control to select a memory bank
(p. 106).
●
●
While the RIT/∂TX is ON:
Rotate outer control to shift the receive or
transmit frequency (pgs. 75, 88).
•“ ” or “ ” indicators appear when the RIT or
∂TX function is activate, respectively.
•The shift frequency range is ± 9.999 kHz in 1 Hz
steps (or ±9.99 kHz in 10 Hz steps).
•When the RIT or ∂TX function is ON, push and
hold [F-1
RIT
] or [F-2
∂TX
] for 1 sec. to add or
subtract the frequency shift to the display fre-
quency.
✔
What is the RIT function?
RIT (Receiver Incremental Tuning) shifts the receive fre-
quency without shifting the transmit frequency.
This is useful for fine tuning for stations calling you off fre-
quency or when you prefer to listen to slightly different-
sounding voice characteristics, etc.
✔
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.
yTWIN PBT (M-ch/RIT) INDICATOR
(pgs. 75, 79, 88, 102)
➥Indicates the status of [PBT/M-ch/RIT] (t) acti-
vates as the Twin PBT function or memory chan-
nel/RIT control.
•Indicator is green when the Twin PBT is selected.
•Indicator is off when the M-ch/RIT is selected.
•Indicator is orange when the RIT or ∂TX function is
activate.

iTUNER/CALL KEY [TUNER/CALL]
➥During HF/50 MHz operation (p. 116):
●
●
Push momentarily to toggle the automatic an-
tenna tuner function ON and OFF.
•An optional antenna tuner must be connected.
•“ ” indicator appears when the tuner is ON.
●
●
Push and hold for 2 sec. to manually tune the
antenna.
•An optional antenna tuner must be connected.
•“ ” indicator appears when the tuner is ON.
➥During 144/430 MHz operation (p. 102):
Push momentarily to select the call channel (or
return to the previous channel/frequency when
the call channel is already selected).
•“C1” is the 144 MHz call channel and “C2” is the 430
MHz call channel.
oMULTI-FUNCTION KEYS [F-1]/[F-2]/[F-3]/[F-4]
