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.) Fig. 4-6
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.

8. Place the @ode switch to CW, M s r ! switch to Ip. Close
the key and IMMEDIATELY r e d i ~ the P L - control.
Reduce the carrier control 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. Fig. 4-8
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.
