FC-40 External Automatic Antenna Tuner Instructions

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 FC40 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.
Depending on the installation and location of some antennas, it may not be possible to tune to a low SWR.
Interconnections to FT-710
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-710 Transceiver.
Turn OFF the external power supply switch and the FT-710 power supply switch first before connecting the cables.

Setup the transceiver
The optional FC-40 Automatic Antenna Tuner provides automatic tuning of a coaxial line to present nominal 50-ohm impedance to the FT-710’s ANT jack. Before tuning can begin, the FT-710 must be configured to recognize that the FC-40 is being used. Configuration is done using the Setting Menu Mode:

1. Press the [FUNC] knob.
2. Select [OPERATION SETTING] → [GENERAL] → [TUNER TYPE SELECT].
3. Rotate the [FUNC] knob, or touch “<” or “>” on either side of the value to select “EXT”.
4. Press the [FUNC] knob to save the new setting.
5. Touch [BACK] several times to return to normal operation.

Tuning Operation

1. Press the [TUNE] key.
   A “TUNE” icon will appear in the display; and the tuner function is activated.

2. Press and hold the [TUNE] key to begin automatic tuning.
   ● The transmitter will be engaged, and the “TUNER” icon will blink while tuning is in progress.
   ● When the optimum tuning point has been reached, the transceiver will return to receive, and the “TUNER” icon will again glow steadily (instead of blinking).
   • Be sure to connect a good earth ground to the GND terminal of the FC-40.
   • The carrier signal transmits continuously while tuning is in progress. Please monitor the operating frequency before beginning the tuning process. Be sure you are not interfering with others who may already be using the frequency.
   • It is normal to hear the sound of the relays while tuning is in progress.
   • If the impedance cannot be matched by the FC- 40 better than 2:1, and the “HI-SWR” icon blinks, the microprocessor will not retain the tuning data for that frequency, as the FC-40 presumes that you will want to adjust or repair the antenna system to correct the high SWR condition.

FH-2 Remote Control Switches

With the optional remote-control keypad FH-2 voice messages may be recorded and transmitted (Voice Memory). The FH-2 is also the control of the Contest Memory Keyer during CW operation.

• SSB / AM / FM modes have five voice memory channels (90 seconds each) for storage and playback, of voice recordings.
• The CW Memory Keyer has 5 channels each for the MESSAGE Memory and the TEXT Memory.

1. Voice Memory: 5 Memory Channels for the Memory Keyer In the case of Voice Memory, up to 90 seconds of audio may be stored on each channel. “MESSAGE Memory” and “TEXT Memory” are available for the Contest Memory Keyer. Each “MESSAGE Memory” channel is capable of retaining a 50-character CW message  using the PARIS standard for characters and word length. Each “TEXT Memory” channel is capable of retaining a maximum of 50 characters.

2. Cursor Keys
   When programming the Contest Memory Keyer, these keys are used to move the cursor and select the text characters. The cursor may be moved in 4 different directions
   (up/down/right/left).
   NOTE: Usually, these keys are used for changing the VFO frequency. Press the [ ]/[ ] keys to change the frequency in the same increments as the microphone [UP]/[DWN] switches. Press the [ ]/[ ] keys to change the frequency by 100 kHz steps.

3. LOCK Switch
   The FH-2 key keys may be locked by setting thisswitch to “ON”.

4. MEM Key
   Press this key to store either a Voice Memory, or a Contest Keyer Memory.

5. DEC Key
   When utilizing the sequential contest numbercapability of the Contest Keyer, press this key todecrement (decrease) the current Contest Number by one digit (i.e. to back up from #198 to #197, etc.).
   *No function is assigned to the [P/B] key.

Resetting the Microprocessor

Memory channels, setting menus, and various settings can be initialized and returned to their factory defaults.

1. Display the reset item selection screen. Press the [FUNC] knob → touch [EXTENSION SETTING] → touch [RESET]

2. Touch “DONE” of the item you want to reset (see below). Or Select an item with the [FUNC] knob and press the [FUNC] knob.
   A confirmation screen for reset execution is displayed. MEMORY CLEAR (Memory Reset)
   Only the contents of the memory channel are initialized (factory default).
   All stored information will be erased, but channel M-01 will return to the initial setting of 7.000.000 MHz, LSB.
   MENU CLEAR (Setting Menu Reset)
   Only the contents of the setting menu are returned to their default values (factory default). ALL RESET (All Reset)
   Initializes all settings of this unit, including various settings, memories, and setting menus, and restores the factory settings.

3. Touch [OK] or select [OK] with the [FUNC] knob and press the [FUNC] knob to execute the reset.
   To cancel the reset, touch [CANCEL] or select [CANCEL] with the [FUNC] knob and press the [FUNC] knob.

4. The power is turned OFF once and then turned ON automatically.
   The reset is complete.
