LOAD.  SET R15 TO FULLY CLOCKWISE POSITION MAXIMUM AMPLITUDE AND SET SW1 TO
FULLY COUNTERCLOCKWISE POSITION MINIMUM AMPLITUDE.  THEN SET THE DRIVE
CONTROL ON YOUR TRANSMITTER TO MINIMUM AND ENSURE THAT THE ALC IS OFF.  SET
YOUR DIGITAL PROGRAM TO RTTY OR PSK31 AND ENABLE IT TO TRANSMIT AUDIO
TONES.  ADVANCE YOUR DRIVE CONTROL TO WHERE IT WOULD NORMALLY BE FOR A CW
OR SSB TRANSMISSION.  TURN STEP ATTENUATOR SW2 CLOCKWISE UNTIL YOU GET AT
LEAST 50 W POWER, ASSUMING YOUR TRANSMITTER RATED OUTPUT IS 100 W.  THE
POWER OUTPUT FROM THE TRANSMITTER SHOULD SMOOTHLY GO UP AND DOWN AS YOU
ROTATE R15 THROUGH ITS RANGE.  AN ERRATIC POWER OUTPUT WHEN YOU ROTATE R15
WHEN TRANSMITTING MAY INDICATE THAT YOU HAVE AN RFI PROBLEM.  FINALLY,
ADJUST R15 FOR 20 W OUTPUT POWER.  RETURN YOUR DATA COMMUNICATIONS PROGRAM
