3.5 Setting The Output Power
Note 1: The PA cover shield should be in position when the metering and power
controls are set up.
Note 2: The actual power used may be limited by regulatory requirements (e.g. NZ
33W, Australia 50W).
Once the PA has been tuned to full power, set the output power by adjusting RV32
(the front panel power adjust control) to any desired output power between 10
and 60W.
3.6 Remote Forward Power Meter Calibration
If a remote meter is connected, adjust RV16 (forward power meter) for the remote
reading to agree with the RF power meter reading.
3.7 Remote Reverse Power Meter Calibration
If a remote meter is connected, connect a 50 ohm 3dB pad (with the output open
circuit) to the PA output.
Apply RF drive and Tx key.
Adjust RV8 (reverse power meter) for a quarter of the forward power reading.
