[. . . ] The default condition for the ARS is "ON" for both bands. See page 85 for details on disabling the ARS, if desired. Note: With the ARS turned On, the repeater shift icon will not initially appear when you enter a frequency directly from the keypad. However, if you move the Main tuning Dial or MEM/VFO CH knob, or initiate scanning in either direction, the ARS feature will be activated, and the appropriate repeater shift will be applied. Setting the Repeater Shift The repeater shift has been set, at the Yaesu factory, to the value most likely to be correct for your location. However, you may have the need to change the repeater shift especially on a band like 50 MHz, where several shifts may be popular even within the same country (e. g. 500 kHz, 1 MHz, and 1. 7 MHz in the United States). Check with your local repeater coordinator or a repeater guide for confirmation of the appropriate shift in your area. The default repeater shift may be changed independently on each of the four FT-847 bands on which repeater operation is authorized. The setting of the repeater shift is accomplished using Menu items #16 through #19 for the 29 MHz through 430 MHz bands, respectively. Here is an example of how to change the repeater shift to 1. 70 MHz on the 50 MHz band: l Press the [MENU] button to activate the Menu mode of operation. l Rotate the SUB-TUNE knob to select Menu #17 ("50M-RPT"). l Rotate the MEM/VFO CH knob to set the value to 1. 70 MHz. The available range of repeater shifts is 0 ~ 99. 99 MHz. l Press the [MENU] key to exit the Menu mode. An identical procedure is used to set the shifts on the other repeater bands. Remember that this procedure only sets the amount of the repeater offset; the direction of the repeater shift ("+" or "­ ") is set using the [1(RPT)] key. Note: If you wish to access a single repeater which uses a shift different from the default shift, it is not necessary to follow the above procedure (which will make operation on other repeaters inconvenient). For the one repeater using a nonstandard split, use the "Split Memory" capability of the memory system. See page 72 for details. Manual Repeater Shift For repeater operation on 29 or 50 MHz, or on the 144/430 MHz bands when ARS is disabled, it is easy to activate or change the repeater shift manually. · While operating in the FM mode (see previous section), press the keypad's [1(RPT)] key. The "­ " icon will appear on the display, indicating a downward repeater shift. , Press the [1(RPT)] key once more to change the direction of the repeater shift to the upward direction. The "­" icon will change to "+" on the display. [. . . ] If you are sending a 1500 Hz tone, instead, set the VFOs to a frequency 1500 Hz below the "schedule" frequency, etc. During your first transmission, adjust the MIC (GAIN) control to the position just before the point where the power output no longer increases. Then adjust the RF PWR control for about 25 Watts output on 144 or 432 MHz (50 Watts on 50 MHz). The duty cycle during HSCW is much higher than with slower-speed CW or SSB, and reducing the power output from the FT-847 to about 50% of its rated maximum is therefore recommended. [. . . ]
