ANT A
RF Output Connector. Connect the coax cable to the antenna.
‡ A ANT B
RF Output Connector. Connect the coax cable to a second antenna or a dummy
load (50ƒ ¶
‡ B INPUT
RF Input Connector. Connect the coax jumper cable from the transceiver.
‡ C AC POWER
AC Mains Socket. Socket for the AC power cord. (Socket is EMI filtered.)
‡ D GND
Ground Terminal.
‡ E SEND
RCA Jack. Connect the control cable from the ACC terminal (or SEND, TX GND
etc.) of the transceiver. The center pin is to be shorted to ground through the relay
circuit of the transceiver for the amplifier to be keyed. The DC current flowing into
your radio to key the amplifier to transmit is as low as 5V, 1mA.
‡ F ALC
RCA Jack for ALC Voltage Output. Negative DC voltage appears at the center pin,
which is fed back to the ALC terminal of the transceiver. ALC is used to keep the
amplifier output power at certain limits. Also it is useful when the transceiver output
power is higher than 100W. (See page 13. 8. ALC Connection). Also consult your
HF transceiver's user manual.
‡ G ALC ADJ.
Potentiometer to adjust ALC voltage level. Minus 10V is available at maximum,
when turned full counter-clockwise. Factory setting is 0 volts, with the pot turned
full clockwise.
‡ H FUSE
A pair of fuses for AC Mains. 15A glass fuse. (Change to 25A fuses if 115V line
voltage is selected.)
1kW for example).
