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