Operation Manual

OUTPUT POWER ALC (optional)
The amplifier provides an output power of 1000 - 1200 watts in HF bands. For 50
MHz, the output power does not exceed 900 watts. The input level is different in
each segment; the use of ALC is recommended for constant output in all bands
without regulating the input power.
How to adjust ALC for maximum power:
1. Connect an RCA-type cable from the ALC port on the amplifier (1) to the ALC
port on the transceiver. Some radios do not have an RCA-type output for ALC.
2. Turn the regulator completely to the left, counter-clockwise.
3. Set the transceiver output to 40-60 watts. The 20-meter band is recommended
for this adjustment.
4. Begin to modulate and turn the regulator to the right, clockwise, noting that the
power will be low and will begin to rise (2).
5. Stop when you see the level bar in approximate peaks of 1000 watts. Some
radios have a narrow adjustment.
WARNING: Use an input power less than 35-watts for (RTTY, CW, AM, FM, DATA) Modes.
