ˆ The TX/RX switching in the linear amplifier is con-
trolled by switching components in the transceiver. The
relay circuit of the
FT-2000D
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 “
146 tGEn ETX-GND ;” set this Menu
item to “
EnA EnA
EnA EnA
EnA
(Enable)” to activate the amplifier switch-
ing relay.
ˆ The specified range for ALC voltage to be used with
the
FT-2000D is 0 to –4 Volts DC.
ˆ Amplifier systems utilizing different ALC voltages will
not work correctly with the
FT-2000D , and their ALC
lines must not be connected if this is the case.
