Note: ◆ TF-SET is disabled while transmitting. ◆ You can change the transmission frequency even when the Frequency lock function is ON. ◆ An RIT offset frequency is not added; however, an XIT offset frequency is added to the transmit frequency during TF-SET. ◆ The TF-SET function does not operate in Simplex mode. However, when the XIT function is ON and the RIT function is OFF, the TF-SET function will operate in Simplex mode. In this situation, you can set the XIT frequency while operating TF-SET by rotating the Tuning knob or pressing the MIC [UP] / MIC [DWN] keys. SHIFTABLE RX FREQUENCY DURING SPLIT TRANSMISSION As the factory default setting, when rotating the Tuning knob during split transmission, the transmit frequency will change. By following the procedures below, when rotating the Tuning knob during split transmission, you can change the receive frequency. 1 Press [MENU], then press [Q-M.IN]/ [Q-MR] or turn the MULTI/CH control to select Menu No. 20. 2 Press [M.IN]/ [SCAN (SG.SEL)] to select "on". 3 Press [MENU] to exit Menu mode. • When you switch the transceiver ON while this function is set to ON, the decimal point at the right end digit of the main display flashes for approximately 2 seconds after the Power On message is displayed. FM REPEATER OPERATION Most Amateur radio voice repeaters use a separate reception and transmission frequency. The transmission frequency may be higher or lower than the reception frequency. In addition, some repeaters may require the transceiver to transmit a subtone before the repeater can be used. Compared to simplex communication, you can usually transmit over much greater distances by using a repeater. Repeaters are typically located on a mountain top or other elevated location. Often they operate at higher ERP (Effective Radiated Power) than a typical station. This combination of elevation and high ERP allows communications over considerable distances. HF/ 6 m band repeaters usually operate in the 29 MHz FM sub-band and 51-54 MHz band. This special service combines the advantages of FM operation, good fidelity with noise and interference immunity, with the excitement of HF DX (long distance) communications. Even on a quiet day, 10 m FM provides reliable around-town communications with the potential for sudden DX from across the country or around the world. ENHANCED COMMUNICATIONS 6 Note: ◆ When programming 2 separate frequencies using 2 VFOs, be sure to select FM mode on both VFOs. ◆ When operating through a repeater, over deviation caused by speaking too loudly into the microphone can cause your signal to "talk-off" (break up) through the repeater. 29.520 MHz 88.5 Hz 29.620 MHz 29.620 MHz 29.520 MHz 88.5 Hz 1 Press [A/B (A=B)] to select VFO A or VFO B. • " " or " " appears to show which VFO is selected. 2 Turn the Tuning control or the MULTI/CH control to select the reception frequency. 3 Press [FM/AM (FM-N)] to select FM mode. 4 Press and hold [A/B (A=B)] to duplicate the frequencies and other data to the other VFO. 5 Turn the Tuning control or the MULTI/CH control to select the transmission frequency. 6 Press [AGC/T (SEL] to turn the Tone function ON if the repeater requires a subtone. • " " appears. • Refer to "Selecting a Tone Frequency" for more details on the subtone {page 26}. • To quit the Subtone function, press [AGC/T (SEL)] twice. 7 Press [SPLIT]. • " " appears. 8 Press [A/B (A=B)] to return to the original reception frequency. 9 Press Mic [PTT] to transmit. • The VFO changes to the other VFO to transmit. • Each time you press [A/B (A=B)], the reception and transmission frequencies are swapped. 10 Press [SPLIT] to quit split-frequency operation. • " " disappears. 25
