Automatic-Matching 200-Memory Antenna Tuner FC-40 Installation Instructions Thank you for your purchase of the model FC-40 Automatic-Matching 200-Memory Antenna Tuner. The FC-40 microprocessor con- trolled antenna impedance matching network is designed to provide wideband transmitting capability for many Vertex Standard / Yaesu transceivers?, when used with an end-fed random wire or long whip antenna. 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 1.6 - 54 MHz, 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. The FC-40 is a current feed design and may not be able to match frequencies that are near 1/2 wavelength (or multiple) of the antenna element. ?: Check with your Vertex Standard /Yaesu dealer for a list of current transceivers that may be used with the FC-40 Antenna Tuner.

Do this in the event of erratic operation of the tuner, or to clear the tuners memories. Cautions ? Only connect cables to the FC-40 after switching the trans- ceiver off. ? If the FC-40 doesnt tune even though you have pushed the TUNER switch of the transceiver, it may be because the an- tenna or its coaxial cable has a serious problem (very high or low impedance due to “open” or “short”) or (the antenna ele- ment is near 1/2 wavelength or multiple of the desired fre- quency). Please check the antenna and coax if this happens. ? Take appropriate measures to ensure that there is no possibil- ity that someone may come in contact with the antenna or FC-40 ANT terminal while your station is transmitting. Ob- serve all practical and regulatory requirements for protecting yourself and the public from the effects of radio frequency radiation from your antenna system.

Please note the default positions of the internal DIP switch components. All switches, except for the 4th switch of S1003, are for factory setup use only, and they should not be touched.

In all installations, however, the FC-40 must be located at the intended feedpoint for the antenna. The drawings below show examples of placement of the FC-40 in typical mounting locations. Following are several important considerations to bear in mind during installation: ? The side of the FC-40 with the cables extruding is oriented downward (to minimize the chance of water leakage through the cable holes). ? The grounding wire (for monopoles) and part(s) of the an- tenna wire between the tuner terminals and the nearest an- tenna support should be as short as possible. ? The antenna must not touch anything except supporting insu- lators. ? If there is any chance of stress on the cables to the trans- ceiver, they should be supported independently, with a slack loop between their support and the FC-40. For base stations, the FC-40 may be mounted either on a flat sur- face such as the wooden board shown in Figure 1, or a 2.16” - 2.55” (55-65 mm) mast, using the supplied U-bolt kit shown in Figure 2. For mobile installations, the FC-40 should be bolted to a flat sur- face using either bolts or self-tapping screws (Figure 3) inside the trunk or cabin, as close to the base of the antenna as possible. Note that it can be mounted horizontally if well protected from the weather. After mounting the FC-40, connect the cables from the FC-40 to the ANT and TUNER (or CAT/LINEAR) jacks (depends on the transceiver) on the rear panel of the transceiver. Refer to the transceivers Operating Manual for details of the interconnec- tions with the transceiver. If you use the FC-40 with the Yaesu FT-857D/-897D transceiver, refer to the instructions on the op- posite page of this manual for interconnection details.

The FC-40, working in concert with the FT-897D/-857D trans- ceiver, can store impedance matching data in its micro-computer memory, so as to provide instant adjustment as you transmit in different areas of a particular band. A total of 200 memories are provided, with the capability to resolve new tuning data every 10 kHz. A few guidelines should be noted regarding the FC- 40s memory system: Tuning data is stored when you make an active effort to store it by pressing and holding in the A(TUNETUNETUNETUNETUNE) key for one second. Although the tuner will automatically activate itself if it encoun- ters more than 2:1 SWR, this memory will not be stored unless you have pressed the A(TUNETUNETUNETUNETUNE) key for one second. This al- lows you to store your favorite operating frequency areas into tuner memory without tying up memory space with matching data on seldom-used frequencies. If the FC-40 cannot resolve a satisfactory match because the SWR is above 2:1), the tuning process will stop, and no memory data will be stored. However, you may wish to move frequency a few kHz, then press the A(TUNETUNETUNETUNETUNE) key again for one second, as slight changes in the reactance may allow a match to be ob- tained. Then go back to the original frequency and try again. If the impedance encountered by the FC-40 exceeds 2:1, and the “HSWR” icon is illuminated, the microprocessor will not retain the tuning data for that frequency, as the FC-40 presumes that you will want to adjust or repair your antenna system so as to correct the high SWR condition. BATT-B BATT-A MEM/VFO CH DIALFA 11. Press and hold in the A(TUNETUNETUNETUNETUNE) key to initiate automatic tuning. The FT-897D/-857D transmitter will be activated, a carrier signal will be sent out, and the coils and capacitors in the FC-40 will be selected/adjusted for optimum SWR. When tuning is complete, the transmission will cease, and you will be ready for operation on this frequency. Tuning data will be stored in the FC-40s Memory system. See the discussion below for details on how this works. If using the FC-40 with the FT-897D under internal battery (FNB-78) power, the FC-40 may not operate properly if the battery voltage is low.
