The lower LED bar-graph will indicate reflected power up to 240W. The scale resolution is 30W.
The OPER button alternatively switches between the operate and standby modes once the amplifier has
completed its 150-second warm-up period (see Section
The RTTY button reduces the output power of the amplifier to 500W (see Section
The button labeled A1-A2 (see Section
or antenna 2, according to the operator's choice. It is the operator's responsibility to connect suitable
antennas to the ANT1 and ANT2 connectors on the rear panel of the amplifier.
The red TX LED illuminates whenever the KEY-IN input is keyed (closed to ground), i.e. when the transceiver
goes into the transmit mode (see Section
The BAND knob controls the band switch, and LOAD and TUNE are used to adjust their respective variable
air capacitors in the amplifier's output circuit. The settings of these three controls must be changed at each
band change as well as when an antenna is changed. The three LED indicators located above the knob
LOAD are called the "TRI tuning indicator" and they are used to achieve antenna impedance matching
during a re-tune procedure (see Section
To avoid damage not covered by the amplifier's warranty, do not turn the BAND switch
while transmitting. Switching while transmitting is called "hot switching" and it will
cause irreparable damage to the band switch.
There are three warning LED indicators and one fault LED indicator located in the bar-graphs area. The
following describe the error conditions and the correct responses (except for the service functions – see

safe operation;
G2 - when illuminated, a screen-grid overload condition exists; reduce the drive power
•
and/or refresh the tuning (see Section
IP - when illuminated, a plate current overload condition exists; reduce the drive power
•
and/or refresh the tuning (
F – when illuminated, the amplifier automatic protection has tripped. If F is accompanied
•
with one of the G1, G2, or IP condition indicators, the cause of the protection trip will be
evident. When F alone is illuminated, check the keying wiring (see Section
