Interfacing to Other Linear Amplifiers

Note
G The TX/RX switching in the linear amplifier is controlled by switching components in the transceiver. The relay circuit
of the FT 9000D used for this switching is capable of switching AC voltage of 100 Volts at up to 300 mA, or DC

voltages or 60 V at 200 mA or 30 V at up to 1 Amp. In order to engage the switching relay, use Menu #156 (EXT AMP
TX-GND) within the "TX GNRL" Menu Group; set this Menu selection to "ENABLE" to activate the amplifier switch-
ing relay.
G The specified range for ALC voltage to be used with the FT
G Amplifier systems utilizing different voltages will not work correctly with the FT
be connected if this is the case.
