Operation of the Transceiver has been simplified as much as
possible to permit rapid adjustment by the operator. Once
Figure 1-18 illustrates the meter face. The figures 0 to 9
under the left half of the arc are read as ‘’S units,” and the
figures above the right half of the arc are read as “decibels

current is adjusted.
The ALC {automatic fevel control) position of the meter
switch results in ““S Meter’ action during reception, and
indicates the relative ALC voitage during transmission. No S$

the initial settings have been made, it should not be
necessary to readjust most of the controls. Read the
following information carefully. Good operating techniques
will provide good clean signals and long trouble-free life of
the Transceiver.
CAUTION: Be sure a 50 to 75 Q nonreactive load is
connected to the ANTENNA jack before operating the
Transceiver. This load can be an antenna, a dummy load, or
a properly adjusted linear amplifier. (See the “Installation”
section of the Manual on Page 131).
The PLATE position of the switch causes the meter to read
cathode current to the final stages. There are six numbers on
the S Meter (in additon to 0). When reading cathode current,
each number represents 50 milliamperes. Thus:
