RECEIVE AND TRANSMIT
■
RIT and
∂
∂
TX
• RIT function
The RIT function shifts the receive frequency up to
±9.999 kHz in 1 Hz steps (10 Hz steps when can-
celling the 1 Hz step readout) without moving the
transmit frequency.
• See
#2
on p. 6 for function description.
q
Push the [RIT] switch.
w
Rotate the [RIT/
∂
TX] control.
e
To reset the RIT frequency, push [CLEAR] for
1 sec.
• Push [CLEAR] momentarily to reset the RIT frequency
when the quick RIT/
∂
TX clear function is ON. (p. 72)
r
To cancel the RIT function, push [RIT] again.
• “

TX function
The

ceive frequency.
• See
#3
on p. 6 for function description.
q
Push the [

appears.
When RIT and
∂
TX are ON at the same time, the [RIT/
∂
TX] control shifts both the
transmit and receive frequencies from the displayed frequency at the same time.
• Calculate function
The shift frequency of the RIT or
∂
TX function can
be added/subtracted to the displayed frequency.
While displaying the RIT and/or
∂
TX shift frequency,
push [RIT] or [
∂
TX] for 1 sec.
• Practical example
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.
q
Push [RIT] and [
∂
TX] to turn both the RIT and
∂
TX functions ON.
w
Rotate [RIT/
∂
TX] to find the DX station’s receive
frequency.
e
When you find the DX station’s receive frequency,
push [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).
r
Start transmitting while the station is standing by.
