5, Place MODE switch to TUNE, METER switch to ALC.
Peak the DRIVE control. If the meter pegs or goes out
of the ALC range, reduce the CARRIER control setting
for an on-scale reading. (the CAR control is a level
adjustment, while the DRIVE control is a resonating
adjustment.)
NOTE: - —
The TUNE position permits tuning of the final tank circuit at
reduced power without danger to the tubes. In the TUNE
position, the screen voltage to the finals is reduced
approximately 50% and the keying circuit is closed.
Adjust DRIVE control for
maximum on-scale meter deflection.

then the LOAD control alternately to
peak (maximum meter deflection) power output.

7. Place the meter switch to RF and peak the LOAD
control
8. Place the Mode switch to CW, Meter switch to Ip.
Close the key and IMMEDIATELY redip the PLATE
control. Reduce the carrier contr-| setting if Ip reads
over 265ma. Open the key.
9. Place the meter switch to RF.
Close the key and repeak the LOAD for maximum RF
output. You may at your option also redip the PLATE
for maximum RF output.
Open the key. You are tuned up for CW operation. If
necessary, adjust the RF METER control on the rear pa-
nel to bring the output reading to about 2/3 scale.
This is a meter adjustment, not an output adjustment.
NOTE:
Dip point may not always coincide with maximum output,
because neutralization is accomplished on the 10 meter
band.
For this reason, you may simply adjust both the PLATE and
the LOAD controls for maximum output as described in both
tune-up procedure and summary Table 4-1.
