6FUNCTIONS FOR TRANSMIT

Split frequency operation

Split frequency operation allows you to transmit and receive in the same mode on two different frequencies. The split frequency operation is basically performed using 2 VFO frequencies (VFO A and VFO B) on the main and sub readouts.

The following is an example of setting 21.290 MHz for

 

 

receiving and 21.310 MHz for transmitting.

[MENU/GRP] [F-1] [F-2] [F-4]

[DIAL]

 

q Select VFO A and set the frequency to 21.290 MHz (USB).

[F-4V/M] is available when M-2appears.

[F-2A/B] is available when M-1appears.

w Push [F-1SPL] momentarily (in the M-1menu) to turn the split function ON, then push [F-2A/B] (M- 1) for 1 sec.

•The equalized transmit (VFO B) frequency and “ ” appear on the LCD.

•The quick split function is much more convenient for selecting the transmit frequency. See the next page for details.

e Rotate [DIAL] while pushing [F-4XFC] (M-1) to set the transmit frequency to 21.310 MHz.

[XFC] on the HM-151 can also be used.

•The transmit frequency can be monitored while pushing [F-4XFC].

r Now you can receive on 21.290 MHz and transmit on 21.310 MHz.

To swap the transmit and receive frequencies, push [F-2A/B] (M-1) to exchange the VFO A and VFO B.

DIRECT SHIFT FREQUENCY INPUT

The shift frequency can be entered directly.

q Push [F-INP/ENT](HM-151).

w Enter the desired shift frequency with the digit keys.

•1 kHz to 1 MHz shifts can be entered.

•When you require a minus shift direction, push [50/•] before entering the shift.

e Push [F-1SPL] (M-1) on the transceiver’s front panel.

•The shift frequency is input in the sub readout and the split function is turned ON.

SPLIT LOCK FUNCTION

Accidentally releasing [F-4XFC] (M-1) while rotating [DIAL] changes the receive frequency. To prevent this, use both the split lock and dial lock functions to change the transmit frequency only. The split lock function cancels the dial lock function while pushing [F-4XFC] (M-1) during split frequency operation.

The dial lock’s effectiveness during split frequency op- eration can be selected in the miscellaneous (others) set mode for both receive and transmit frequencies; or only the receive frequency. (p. 131)
