NTERFACING TO
The TX/RX switching in the linear amplifier is controlled by switching components in the transceiver. The
relay circuit of the FT
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 175 EXT AMP TX-GND" within the "TX GNRL" Menu Group; set this Menu selec-
tion to "ENABLE" to activate the amplifier switching relay.
The specified range for ALC voltage to be used with the FT
Amplifier systems utilizing different voltages will not work correctly with the FT
lines must not be connected if this is the case.
