FUNCTIONS FOR TRANSMIT

■ ∂TX function

The

∂TX function shifts the transmit frequency up to

±9.999 kHz in 1 Hz steps (10 Hz steps when can-
celling the 1 Hz step readout) without moving the re-
ceive frequency.

qPush [PBT/M-ch/RIT] momentarily to select the M-

ch/RIT function, if the twin PBT is selected.

•

[PBT/M-ch/RIT] indicator (Green) goes out.

wPush [PBT/M-ch/RIT] for 1 sec. to enter the

RIT/

∂TX mode.

ePush [F-2 ∂TX] to turn the ∂TX function ON.

• “

” indicator and the frequency shift appear and

[PBT/M-ch/RIT] indicator lights orange when the func-
tion is ON.

rRotate [RIT] (outer) control to shift the transmitter

frequency.

• The receive frequency is not shifted.

tTo reset the ∂TX frequency, push [F-3 CLR] for

1 sec.

• Push

[F-3 CLR] momentarily to reset the RIT fre-

quency when “Quick  RIT/∂TX  Clear” in the
miscellaneous (others) set mode is ON. (p. 135)

yTo cancel the ∂TX function, push [F-2 ∂TX] mo-

mentarily again.

• “

” indicator disappears.

uPush [Z(

)] to exit the RIT/

∂TX mode.

When RIT and 

∂TX are ON at the same time,

[RIT] (outer) control shifts both the transmit and re-
ceive frequencies from the displayed frequency at
the same time.

[RIT] (outer)

The frequency shift of the (RIT or) 

∂TX function can

be added/subtracted to the displayed frequency.

While displaying the (RIT and/or) 

∂TX shift fre-

quency, push and hold (

[F-1 RIT] or) [F-2 ∂TX] for

1 sec.

When you find a DX station on 21.025 MHz/CW and
the station is picking up stations transmitting slightly
up from 21.025 MHz.

qPush [F-1 RIT] and [F-2 ∂TX] to turn both the

RIT and 

∂TX functions ON.

wRotate [RIT] (outer) to find the DX station’s re-

ceive frequency.

eWhen you find the DX station’s receive frequency,

push

[F-1 RIT] to turn the RIT function OFF.

• Now you can transmit the DX station’s receive fre-

quency and receive the DX station’s transmit fre-
quency (21.025 MHz).

rStart transmitting while the station is standing by.

Push and hold
