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 16.5Ω to 150Ω (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

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

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

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

By changing the configuration of an internal DIP switch,
you may change the RF signal path (to enable the FC­30 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 re­ceiving.

1. Turn the FT-897 POWER switch OFF.

2. Remove the 6 screws affixing the case of the FC­30, then remove the case.

3. Turn the 8th switch of S1003 to "on."

4. Replace the case, using the 6 screws removed in
step (2) above.

B) Memory clear

1. Turn the FT-897 POWER switch OFF.

2. Remove the 6 screws affixing the case of the FC­30, then remove the case.

3. Turn the 4th switch of S1003 to "on."

4. Turn the FT-897 POWER switch ON.

5. LED0 will glow green, then disappear, after a short
time.

6. Return the 4th switch of S1003 to "off ."

7. Turn the FT-897 POWER switch OFF.

8. Replace the case, using the 6 screws removed in
step (2) above.

Cautions

The bottom case is the
case half that has a
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 FC­30's control circuitry to
overheat.

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 acciden­tally set a switch to the wrong position, please refer to
the table below to correct the situation.

MAXIMUM POWER: 100 Watts

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.
