User manual YAESU FT-8000R

[. . . ] When using the optional FNB-78 NiMH Battery Pack, the FT-8000Rautomatically switches to 20 Watts (430 MHz:10W) of output power. The multi-function Liquid-Crystal Display includes attractive backlighting, which may be disabled for battery conservation. The display includes bar-graph indication of power output, ALC voltage, SWR, and modulation level. Also include are a number of operating status icons, as well as the function displays for the three operating function keys (A, B, and C). Among the advanced features of the FT-8000Rare many incorporated only in large base-station transceivers. [. . . ] Tune the VFO-B frequency to 14. 025. 00 MHz (DX station's transmitting frequency). The transceiver will now transmit using the VFO-A frequency, and will receive using the VFO-B frequency. "Parentheses" will appear on the both sides of the "SPL" indication, and the "SPL" icon will appear at the upper left corner of the display. To listen to the pile-up calling the DX station (so as to align your frequency more closely to that of the station being worked by the DX), press the [A](A/B) key to reverse the VFOs. You will now be tuning in the vicinity of 14. 035 MHz, and you can zero in on the DX station's listening frequency by tuning in on the station in QSO with the DX. Press the [A](A/B) key again to return to reception on the DX station's frequency. Press the [C](SPL) key once more to cancel split operation; the "Parentheses" and "SPL" icon will disappear from the display. TIME-OUT TIMER Most often used on FM, the transmitter's Time-Out Timer (TOT) feature disables the transmitter after a user-defined period of transmission. This feature may be useful in preventing a "stuck microphone" (accidental closure of the PTT switch) from causing interference to other users, and it will also force you to keep your transmissions short, thereby conserving battery power. The default setting for this feature is "OFF. " Rotate the DIAL knob to set a new time-out setting (from 1 minute to 20 minutes). When you have made your selection, press and hold in the [F] key for one second to save the new setting and exit to normal operation. Page 40 FT-8000ROPERATING MANUAL TRANSMITTER OPERATION ACTIVE-TUNING ANTENNA SYSTEM (ATAS-100/-120) OPERATION The optional ATAS-100/-120 Active-Tuning Antenna System provides operation on a number of HF bands (7/14/21/ 28 MHz) plus 50 MHz, 144 MHz, and 430 MHz. The FT897D provides microprocessor control of the tuning mechanism in the ATAS-100/-120 for convenient automatic tuning. Press the [F] key, as needed, to recall Multi Function Row "k" [TUNE, DOWN, UP]. Press the [A](TUNE) key to turn the ATAS-100/-120 on (this action only supplies voltage to the antenna at this point; re-tuning does not begin). "Parentheses" will appear on the both sides of the "TUNE" indication, and the "ATAS" will appear on the LCD. Now press and hold in the [A](TUNE) key for one second to initiate ATAS-100/-120 tuning. The transmitter will automatically be activated, a carrier will be sent, and the antenna's length will be adjusted for best SWR. If the microprocessor determines that the antenna's length is radically incorrect from the optimum value, no carrier will be sent out. Instead, in the receive mode, the antenna will retract to its shortest position (this may take up to one minute). When the ATAS-100/-120 reaches its minimum length, automatic tuning will be initiated, and the transmitter will automatically shut off when a satisfactory SWR is achieved. On the 144 MHz and 430 MHz bands, the ATAS-100/120 does not require a tuning process. When you wish to conclude ATAS-100/-120 operation, press the [A](TUNE) key; the "Parentheses" disappear surrounding the "ATAS" indication.

External Wattmeters If you wish to use an external wattmeter in conjunction with the transceiver and your ATAS-100/-120, please check the wattmeter with an Ohmmeter prior to installation. Be sure there is a direct connection between the "In" and "Out" jacks of the wattmeter (zero resistance), and also ensure that there is a completely open circuit between the center pin and shield of the wattmeter's output jack.
