5 REPEATER OPERATION

■General

When using a repeater, the transmit frequency is shifted from the receive frequency by the offset frequency. It is convenient to pro- gram repeater information into memory channels.

qSet the receive frequency (repeater output frequency).

wPush [4•DUP] after pushing [A•FUNC] several times to select “–” or “+.”

•“–” indicates the transmit frequency is shifted down; “+” indicates the transmit frequency is shifted up.

•Flashing “–” or “+” indicates the reversed duplex mode is selected

in SET MODE (p. 46).

•When the auto repeater function is in used (USA version only) this

selection and step e are not necessary. (p. 24)

ePush [1•TONE] after pushing [A•FUNC] to activate the subaudible tone encoder, according to repeater requirements.

•“ ” appears.

•Select the desired subaudible tone frequency, if necessary. (p. 22) r Push and hold [PTT] to transmit.

•The displayed frequency automatically changes to the transmit fre- quency (repeater input frequency).

•If “OFF” appears, check the offset frequency and direction.

tRelease [PTT] to receive.

yPush and hold [SQL] to check whether the other station’s trans- mit signal can be directly received or not.

About reversed duplex mode

When the reversed duplex mode is selected, the receive fre- quency shifts. (Transmit frequency shifts in normal duplex mode.) Each receive and transmit frequency is shown in the table below with the following conditions;

inputed freq.: 145.30 MHz,	Reversed	OFF		ON
duplex direction : – ,	Rx frequency	145.30	MHz	144.70 MHz
frequency offset : 0.6 MHz
	Tx frequency	144.70	MHz	145.30 MHz
