4 RECEIVE AND TRANSMIT

■Split frequency operation

Split frequency operation allows you to transmit and receive on two different frequencies. Split frequency operation uses 2 frequencies, one in VFO A and the other in VFO B.

Following is an example of setting 7.057 MHz, CW mode in VFO A (for receive) and 7.025 MHz, CW mode in VFO B (for transmit).

•The transmit frequency can be monitored while pushing [(F-3)XFC].

•Split operation is now set for receive on 7.057 MHz/CW and transmit on 7.025 MHz/CW.

➀Select VFO A and set the frequency to 7.057 MHz/CW.

•[(F-2)A/B] is available when M1 appears.

•[(F-3)V/M] is available when M2 appears.

➁Push or push and hold [(F-1)SPL] in the M1 dis- play.

➥Push [SPL]: activates split only.

➥Push and hold [SPL]: activates the quick split below.

➂To change the receive frequency, rotate the main

dial; to change the transmit frequency, rotate the main dial while pushing [(F-3)XFC].

To exchange the transmit and receive frequencies, push [(F-2)A/B] in M1.

CONVENIENT

The G3 display conveniently shows the transmit fre- quency during split frequency operation and [(F-3)Ñ] allows you to change the transmit frequency.

• Split lock function

The split lock function is convenient for changing only the transmit frequency. Otherwise, accidentally releasing the [(F-3)XFC] switch while rotating the main dial changes the receive frequency. The split lock’s effectiveness can be selected in initial set mode (item 12) for both receive and transmit fre- quencies; or only the receive frequency. (p. 52)

DQuick split function

In M1, when you push [(F-1)SPL] for 2 sec., split fre- quency operation is turned ON and VFO B is auto- matically changed according to the plus/minus pre- programmed shift frequency set in initial set mode (or equalized when 0 kHz is programmed as the split shift frequency). This shortens the time needed to start split frequency operation—great for DX’ing.

+10 kHz is programmed as a shift frequency.

The quick split function is ON by default. If desired, it can be turned OFF in initial set mode (p. 51). In this case, pushing [(F-1)SPL] for 2 sec. has the same effect as pushing [(F-1)SPL] momentarily as in nor- mal split operation.

PROGRAMMING SPLIT SHIFT FREQUENCY

➀Push [POWER] to turn power OFF.

➁While pushing [LOCK], push [POWER] to turn power ON and enter initial set mode.

➂Select “SPL OFFSET” using [MENU], [M-CH] or the [Y]/[Z] keys, then rotate the main dial to select the desired split offset.

•The split offset can be selected from –4000 kHz to +4000 kHz.

16 SPL OFFSET

Note: This setting is not valid for FM operation. This is because FM operation uses the duplex setting for repeater operation (next page).
