Providing coverage of the 160-10 meter bands (include the 60 m band: USA version) plus the 6 m, 2 m, and 70 cm bands, the FT-897D includes operation on the SSB, CW, AM, FM, and Digital modes, yielding the most comprehensive performance package available for field operation. Designed for use from (1) an external DC power source, (2) internal battery (requires optional FNB-78 Ni-MH battery pack), or (3) AC power source (requires optional FP30 External AC Power Supply), the FT-897D provides 100 watts of power output from a 13. 8-Volt external power supply or AC operation. [. . . ] The FT897D provides microprocessor control of the tuning mechanism in the ATAS-100/-120 for convenient automatic tuning. Before operation can begin, you must instruct the FT-897D's microprocessor that the ATAS-100/-120 is being used. Press and hold in the [F] key for one second to activate the Menu mode. The default setting for this Menu is "OFF. " Rotate the DIAL to change the setting to "ATAS(ALL), " if you are using the ATAS-100/-120 for all bands (you must connect an external diplexer to combine the two antenna ports so as to use the ATAS-100/120 on all bands). Or make the setting "ATAS(HF&50), " if you are using the ATAS-100/-120 on 7 ~ 50 MHz, with a dual-band VHF/UHF antenna connected separately to the 144/430 MHz antenna port. If you are just using the ATAS-100/-120 on the HF bands only, with a dual-band VHF/UHF antenna connected separately to the 144/430 MHz antenna port (no 50 MHz operation) make the setting "ATAS(HF). " 3. Press and hold in the [F] key for one second to save the new setting and exit to normal operation. Manual Tuning In some instances, the SWR may be slightly improved by manual adjustment of the antenna position. This may be needed for operation on bands like 40 meters, where the "Q" of the ATAS-100/-120 is high, causing a narrow resonance range. Before Manual Tuning, press the [F] key, as needed, to recall Multi Function Row "i" [MTR, -----, DISP], then press the [A](MTR) or [B] key to change the meter function to the SWR meter ("SWR" icon will appear at the upper of the [B] key). To tune the ATAS-100/-120 manually, recall Multi Function Row "k" [TUNE, DOWN, UP], then press and hold in the microphone PTT switch. With the transceiver in the "transmit" mode, press and hold in the [C](UP) key (to raise the antenna) or the [B](DOWN) key (to lower the antenna). While you hold in one of these keys, the FT-897D will generate a carrier, and you may watch the top scale of the FT897D's meter, looking for the meter indication to reach its minimum value. When this is reached, release the [C](UP) or [B](DOWN) key, then release the PTT key to return to the "receive" mode. 1) Once automatic matching has been successfully accomplished, you must change frequency by at least 10 kHz before attempting automatic matching again. Within a window of ±10 kHz from a match point, the transceiver's microprocessor will ignore any command to attempt automatic matching. 2) Antenna tuning is accomplished using a "CW" carrier, although the mode indication will not change to "CW" (if you are operating on another mode) during antenna tuning. 3) If you see a "HI SWR" on the LCD, it may mean that there is a problem in your coaxial cable (bad connection, etc. ) which is preventing successful tuning. Replace the cable, or try adding a few feet/meters of cable (to eliminate the possibility of adverse "transformer action" in the 50 cable during the tuning process). 4) If you are able to achieve an SWR of less than 2:1 via manual tuning, the FT-897D will "accept" the manual setting, and you may then re-tune automatically when changing bands. If, however, you stop manual tuning at a non-optimum setting (SWR >2:1), the FT-897D will not permit further automatic tuning. To refresh the setting of the ATAS-100/-120, press the [B](DOWN) key until the ATAS-100/-120 fully retracts. You may then restart automatic tuning per the procedures described earlier.
