G
The TX/RX switching in the linear amplifier is controlled by switching components in the transceiver. The relay circuit
of the FT
DX
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 “TX GNRL 156
EXT AMP TX-GND” within the “TX GNRL” Menu Group; set this Menu selection to “ENABLE” to activate the
amplifier switching relay.
G
The specified range for ALC voltage to be used with the FT
DX
9000D is 0 to
–
4 Volts DC.
G
Amplifier systems utilizing different voltages will not work correctly with the FT
DX
9000D, and their ALC lines must
not be connected if this is the case.
