PANEL DESCRIPTION
@8 LOCK SWITCH [LOCK] (p. 45)
Turns the dial lock function ON and OFF.
@9 RIT/
∂∂
TX CONTROL [RIT/
∂∂
TX] (p. 34)
Shifts the receive and/or transmit frequency without
changing the transmit and/or receive frequency
while the RIT and/or ∂TX functions are ON.
•Rotate the control clockwise to increase the frequency,
or rotate the control counterclockwise to decrease the
frequency.
•The shift frequency range is ±9.999 kHz in 1 Hz steps
(or ±9.99 kHz in 10 Hz steps).
#0 RIT SWITCH [RIT] (p. 34)
➥Turns the RIT function ON and OFF when
pushed.
•Use the [RIT/∂TX] control to vary the RIT frequency.
➥Adds the RIT shift frequency to the operating fre-
quency when pushed for 2 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.
#1
∂∂
TX SWITCH [
∂∂
TX] (p. 34)
➥Turns the ∂TX function ON and OFF when
pushed.
•Use the [RIT/∂TX] control to vary the ∂TX frequency.
➥Adds the ∂TX shift frequency to the operating fre-
quency when pushed for 2 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.
#2 CLEAR SWITCH [CLEAR] (p. 34)
Clears the RIT/∂TX shift frequency when pushed
for 2 sec.
#3 CW PITCH CONTROL [CW PITCH]
(outer control; p. 29)
Shifts the received CW audio pitch and monitored
CW audio pitch without changing the operating fre-
quency.
#4 MANUAL NOTCH FILTER CONTROL [NOTCH]
(inner control; p. 27)
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 : 0 Hz to 5100 Hz
CW : –900 Hz + CW pitch freq. to 4200 Hz + CW
pitch freq.
AM : –5100 Hz to 5100 Hz
