( Y/ Repeat the adjustments of the CARRIER NULL
control, and the CARRIER NULL capacitor until the
RF output or null reading is about the same on both
the LSB and USB positions of the MODE switch. A
receiver with an S Meter can be used for the carrier
null indication, and it is usually more sensitive for this
purpose,
NOTE: An 11 MQ input voitmeter with an RF probe can
also be used at this time, if one is available, to obtain
additional accuracy in the carrier null adjustments. To nuli
the carrier in this manner, measure the RF voltage with the
RF probe at lug 1 (the center conductor) of the ANTENNA
connector. Then adjust the CARRIER NULL control and
CARRIER NULL capacitor for the lowest RF voltage,
which should be 1/4 volt or ess.
