the antenna, and the antenna tuner must be able to handle at least 1200 watts of carrier or peak
envelope power.
9. Place the amplifier in OPERATE (fig.2 ref 8). Be sure the BAND selected on the amplifier matches the
band selected on the transceiver.
10. Place the transmitter or transceiver into transmit in FM, AM, RTTY, or CW modes. The green TX LED
(fig.2 ref 6) should light. The forward power (fig.2 ref 2) should increase to approximately ten times the
initial reading, the reflected power should remain low, and the PA current should increase slightly on
both scales of the current meter (fig.2 ref 1). No other lights should illuminate.
11. Briefly increase drive power (no more than 100 watts) until the ALS-1300 output is 1200 watts.
12. If ALC is connected between the amplifier and transceiver, rotate the ALS-1300 front panel ALC
control counter-clockwise until the ALS-1300 output power just begins to drop.
13. After you have verified all of this, the amplifier is ready to operate.
