N RIT function

The RIT (Receive Incremental Tuning) function com-
pensates for stations transmitting off-frequency or 
when you prefer to listen to slightly different-sound-
ing voice characteristics, etc.
The function shifts the receive frequency up to  
±9.999 kHz in 1 Hz steps (10 Hz steps when cancel-
ling the 1 Hz step readout) without moving the trans-
mit frequency.

q  Push 

 to turn the RIT function ON.

 • 

“

” and the shift frequency are indicated.

  

- 

 

The shift frequency is indicated for approx. 1 sec., 
then returns to the operating frequency.

 • 

The 

RIT control indicator lights red.

  

- 

 

If the RIT control indicator does not light, push 

. (See below for details)

w  Rotate the [M-CH] control to compensate for off-

frequency stations.

 

• The transmit frequency is not shifted.

 • 

 

The shift frequency is indicated for about 1 sec. when 
rotating the [M-CH] control.

e To cancel the RIT function, push 

 again.

 • 

“

” disappears.

 • 

The RIT control indicator goes out.

 

 The [M-CH] control selects the memory channel 
and also shifts the RIT frequency. Pushing 

 toggles the [M-CH] control as M-CH 

selector or RIT controller.

 

RIT controller: RIT control indicator lights red.

 

M-CH selector: RIT control indicator goes out.

Appears

• RIT monitor function
When the XFC (transmit frequency check function) 
is ON (p. 76), pushing and holding 

 allows you 

to monitor the operating frequency directly (RIT is 
temporarily cancelled).

• Calculate function
The shift frequency of the RIT function can be 
added/subtracted to the displayed frequency.

When the RIT function is ON, push and hold 

* 

for 1 sec.

• The RIT frequency is automatically reset.
*  Available only when the XFC (transmit frequency check 

function) is turned OFF. (p. 76)
