ADVICE: Cont'd
ALC meter deflection may be caused by excessive drive power, but also by relected power detected in the antenna system. If the impedence presented to the transceiver is other than 50 Ohms, ALC meter action may be observed that is not related to the proper setting of the [MIC/SPEED] knob. Therefore, we recommend that you make the [MIC/SPEED] knob adjustments into a dummy load or antenna system presenting impedence very close to 50 Ohms.

In the SSB mode, you may set the desired power output via Menu item "177 TX MAX POWER". The adjustment range is between 5 Watts and 100 Watts. You should always use the minimum power necessary to maintain reliable communications.

When performing "on air" tests (such as the setup of the microphone gain), be sure to check the frequency before transmitting, to avoid interference to others who may already be using the frequency.

Four techniques for excerising Transmit/Receive control are provided on the FTDX1200. You may choose the technique(s) that best suit your operating needs:

    O Pressing the microphone PTT switch will engage the transmiter.

    O The rear panel PTT jack may be connected to a foot switch or other manual switching devise in order to engage the transmitter.

    O Pressing the front panel [MOX] button will lock the transmitter on. Press the [MOX] button again to return to receive.

    O The VOX (Voice Operated Xit) circuit will engage the transmitter automatically when you speak into the microphone. For details of VOX operation refer to page 73.


Adjusting the SSB TX Power Output

    1. Press the [MENU] button to enter the Menu Mode.

    2. Rotate the [VFO-B/CLAR] knob (or press the ▲ / ▼ button) to select Menu item "177 TX MAX POWER".

    3. Press the [SELECT] button, then rotate the [VFO-B/CLAR] knob (or press the ▲ / ▼ button) to adjust the desired power output.

ADVICE:
The value (5 ~ 100) displayed in the Menu list is a relative percentage of the maximum TX power available in the selected mode. It is not the true TX power level.

    4. Press the [SELECT] button, then press the [MENU] button to save the new setting and exit to normal operation.

ADVICE:

The TX Power Output setting cannot be stored in any of the memory channels.
