Instruction Manual
General Notation
On Grounded Grid amplifiers, we do not recommend checking modulation
at higher powers. Grounded Grid amplifiers will not be able to output 100%
modulation in the A.M. mode, however, the feed through power prevents
the grounded grid from being fully modulated. This is the reason A.M.
modulation should be checked at the transmitter, or with the Linear
Amplifier in standby position.

SSB Modulation Check
1. Turn Mode Selector Switch (#5 Fig. 1) to MOD position
2. Switch SSB/AM rocker (#6 Fig. 1) to SSB
3. For this test, the Transmitter must be in AM mode for
setting modulation on meter to the SET line position on
meter. Make sure you use the lower scale marked SSB
MOD.
4. With Transmitter keyed, turn Mode Switch on Transmitter
to either UPPER or LOWER SIDE BAND and talk or whistle
steadily into the microphone. Read modulation on the
lower scale of meter, marked SSB MOD.
