Interconnections to FT-897

Automatic Antenna Tuner

FC-30

Installation Instructions

Thank you for your purchase of the model FC-30 Automatic Antenna Tuner, designed specifically for the FT-897
HF/VHF/UHF Transceiver. The FC-30 includes a cooling fan to ensure thermal stability of the critical matching
elements within its compact case.

The FC-30 Automatic Antenna Tuner responds to control commands from the FT-897 Transceiver, providing
microprocessor-based impedance matching on the 160 through 6 meter Amateur bands. On the HF and 50 MHz
bands the impedance matching range is from 16.5

 to 150

 (up to 3:1 SWR). Accordingly, the FC-30 should

not be expected to match “long wire” type antennas unless you have taken specific design steps to ensure that
the impedance presented to the FC-30 is within these specifications.

Please refer to the FT-897 Operating Manual for operating instructions.

Rear Panel Information

This “M” type (“SO-239”) coaxial jack
accommodate the antenna input for the
FC-30.

Use this “M” type (“SO-239”) jack for
connection of the interconnecting coaxial
cable from the FT-897.

Connect the interconnecting Control
Cable from the FT-897 to this min-
iature DIN connector.

Various setting

By changing the configuration of an internal DIP switch,
you may change the RF signal path (to enable the FC-
30 both on receive and transmit), and you may also
clear all the tuner's memories.

A) By default, the FC-30 is only engaged in the trans-

mit mode. To activate the tuner circuit while re-
ceiving.

Cautions

H

Please note the default positions of the internal DIP
switch components. All switches, except for the 4th
and 8th switches of S1003, are for factory setup use
only, and they should not be touched. If you acciden-
tally set a switch to the wrong position, please refer to
the table below to correct the situation.

H

Only connect cables to the FC-30 after switching the
transceiver off.

H

If the FC-30 doesn't tune even though you have pushed
the TUNER switch of FT-897, it may be because the
antenna or its coaxial cable have a serious problem
(very high or low impedance due to "open" or "short").
Please check the antenna and coax if this happens.

H

Do not place any objects next to the ventilator ducts
on the FC-30, especially those in the front.

The bottom case is the

sponge affixed to the
ventilation screen. If the
case parts are reversed,
the sponge can touch the
fan blades, disabling the
fan and allowing the FC-
30's control circuitry to
overheat.
