External Automatic; Antenna Tuner (For Wire Antenna) - Yaesu FT DX 3000 Operating Manual

Fc-40 e
XteRnAl
The FC-40 makes use of the control circuitry built into the transceiver, which allows the operator to control and monitor
automatic operation of the FC-40, which mounts near the antenna feedpoint. The FC-40 uses specially selected,
thermally stable components, and is housed in a waterproof case to withstand severe environmental conditions with high
reliability.
A carefully-chosen combination of solid-state switching components and high-speed relays allows the FC-40 to match
a wide variety of antennas to within a 2:1 SWR on any amateur band frequency (160 through 6 meters), typically in less
than eight seconds. Transmitter power required for matching may be as little as 4 - 60 Watts, and matching settings are
automatically stored in memory for instant recall when the same frequency range is selected later.
Please see the FC-40 Operating Manual for detailed information.
Interconnections to FT
After mounting the FC-40, connect the cables from the
FC-40 to the ANT and TUNER jacks on the rear panel
of the FT 3000 Transceiver.
DX
Install the supplied ferrite
c o r e a s c l o s e t o t h e
connector as possible.
When the FC-40 is connected to the FT
TX GND (pin 2) of the TUNER jack and the
LINEAR jack (pin 2) are common circuits.
Therefore, the maximum voltage at TX GND (pin
2) of the LINEAR jack must not exceed +5V.
