6 REPEATER AND DUPLEX OPERATIONS ■ Repeater operation When using a repeater, the transmit frequency is shifted from the receive frequency by the offset frequency. (p. 110) This is called duplex operation. It is convenient to program repeater information into memory channels. (p. 74) 144.700 MHz Repeater 144.700 MHz 145.300 MHz 145.300 MHz Uplink (transmitting freq.) Downlink (receiving freq.) Station A Station B q Set the receive frequency (repeater output frequency). w Set the shift direction of the transmit frequency. (-DUP or +DUP; see p. 31 for details.) • When the auto repeater function is in use (U.S.A. version only), this selection and step e are not necessary. (p. 32) "-DUP"or "+DUP" appears. -DUP TONE FM A 145300 1 e Push and hold [TONE](7) for 1 2 sec. to activate the subaudible 3 tone encoder, according to re- peater requirements. 4 • "TONE" appears. [SQL] 5 Refer to p. 121 for tone frequency settings. 7DSQ 6 r Push and hold [PTT] to transmit. TONE 7 • The displayed frequency automati- cally changes to the transmit frequency (repeater input fre- 8 quency). • If "OFF" appears, check the offset frequency or shift direction. 9 (p. 30) 10 While receiving -DUP TONE FM A145300 PSKIP While transmitting -DUP TONE 11 FM A144700 12 PSKIP 13 14 t Release [PTT] to receive. 15 y Push and hold [SQL] to check whether the other station's transmit signal can be directly received or not. 16 U.S.A. version: 17 Auto repeater function uses standard values of the re- 18 peater tone frequency and offset frequency. 19 29
