LOCK/SPEECH SWITCH [LOCK/SPEECH]

➥Push momentarily to toggle the dial lock function

ON and OFF. (p.46)

➥Pushing for 1 sec. announces the S-meter indi-

cation and the selected readout frequency when

an optional UT-102 is installed. (p.74)

#1 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).

#2 RIT SWITCH [RIT] (p. 34)

➥

Turns the RITfunction ON and OFF when pushed.

•Use the [RIT/∂TX] control to vary the RITfrequency.

➥Adds the RITshift frequency to the operating fre-

quency when pushed for 1 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.

#3 ∂∂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

frequency when pushed for 1 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.

#4 CLEAR SWITCH [CLEAR] (p. 34)

Clears the RIT/∂TX shift frequency when pushed

for 1 sec. or when pushed momentarily, depending

on the quick RIT/∂TX clear function setting (p.72) .

#5 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.

#6 MANUAL NOTCH FILTER CONTROL[NOTCH]

(inner control; p. 26)

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
