The TX/RX switching in the linear amplifier is con-
trolled by switching components in the transceiver. The
relay circuit of the
FT
DX
5000
used for this switching
is capable of switching AC voltage of 100 Volts at up
to 300 mA, or DC voltages of 60 V at 200 mA or 30 V
at up to 1 Amp. To activate the amplifier switching
relay, set Menu item “
172 TGEN ETX-GND
” to “
EN-
ABLE
”.
The specified range for ALC voltage to be used with
the
FT
DX
5000
is 0 to –4 Volts DC.
Amplifier systems utilizing different ALC voltages will
not work correctly with the
FT
DX
5000
, and their ALC
lines must not be connected if this is the case.
