Thank you for your purchase of the model FC-50 Automatic Antenna Tuner. The FC-50 is designed specifically for
the FT-891 HF/VHF Transceiver. A cooling fan is incorporated in the tuner to ensure thermal stability of the critical
matching elements mounted within the compact case.
The FC-50 Automatic Antenna Tuner responds to control commands from the FT-891 Transceiver, providing
microprocessor-based impedance matching on the 160 through 6 meter Amateur bands. On the HF bands the
impedance matching range is from 16 Ω to 150 Ω (up to 3:1 SWR) and on the 50 MHz band the impedance
matching range is from 25 Ω to 100 Ω (up to 2:1 SWR). Accordingly, the FC-50 should not be expected to match "long
wire" type antennas unless specific design steps are taken to ensure that the impedance presented to the FC-50 is
within these specifications.
Please refer to the FT-891 Operating Manual for operating instructions.
The FC-50 tuner can be activated during receive (refer to "Activate the tuner during receive" on page three of these
instructions).

Installation to the FT-891
1. Referring to the figure below, remove the four feet and reattach the feet on the bottom of the transceiver with
the supplied screws A (M3x8B) (use a screwdriver).
Do not attach any parts other than the supplied mounting parts .
2. Remove the four rubber caps on the top case of the FC-50.
3. Slide FT-891 with the supplied feet toward the rear of the FC-50, into the slots from which the rubber caps were
removed in step (2) above.
Attach the supplied
feet.
When installing the FC-50 and the FT-891 separately, purchase an additional Mobile Mounting
Bracket(MMB-82), and mount both units securely.

- Page 3 ● Switch the FC-50 OFF before connecting the cables to the transceiver. ● If the FC-50 does not tune when the FT-891 tuner operation is started, there may be a serious antenna or coaxial cable problem (very high or low impedance due to an “open” or “short”). Please check the antenna and coax if this happens.

Como sintonizo la F-50 **** el FT-891
To tune the Yaesu FC-50 with the FT-891:
1. Connect the FC-50 to the FT-891 using the supplied control cable and coaxial cable.
2. Ensure the FC-50 is properly mounted and connected as described (with the supplied mounting parts and screws).
3. Activate the tuner during receive mode using the FT-891’s menu or controls (refer to "Activate the tuner during receive" in the manual).
4. The FC-50 will automatically tune using its microprocessor and stored memory settings.
5. The tuner matches the antenna to the operating frequency automatically. No manual adjustment is needed.
The FC-50 uses up to 200 memory slots to recall previous tuning settings.
