REPEAT MODE 21.1 ANALOG If the received CTCSS/DCS matches the programmed CTCSS/DCS, the radio transmits the programmed carrier frequency and CTCSS/DCS. Hang time is programmable (0-9.9sec), through the “Miscellaneous” tab of the 91-1480CD software. 22.2 DIGITAL Matching NAC (Network Access Code); If the programmed NAC matches the received NAC it allows the radio to repeat. The programmed NAC and TGID (Talk Group Identification), is transmitted. $F7F in RX NAC If the RX NAC is $F7F, all incoming signals are repeated with the same NAC and TGID as received. $F7F in RX NAC w/ Through OFF; If the RX NAC is $F7F, receives all incoming signals and transmits the programmed NAC and TGID. Note: Hang time is programmable (0-9.9 seconds), through the “Miscellaneous” tab of the Base Tech III (91-1480-CD) software. 22.3 MIXED In Mixed mode, the radio receives both Analog and Digital signals automatically. Individual channel programming can be combined as described in a) and b) above.
