6InstallationFT-891 Operating ManualPower connectionThe DC power connector for the FT-891 must only be connected to a DC source providing 13.8 Volts DC (±15%), and capable of at least 25 Amperes of current. Always observe proper polarity when making DC connections:The Red DC power lead connects to the Positive (+) DC terminal; and the Black DC power lead connects to the Negative (–) DC terminal.In mobile installations, noise pickup may be minimized by connecting the DC cable di-rectly to your vehicle’s battery, rather than to the ignition switch or “accessory” circuitry.Direct connection to the battery also provides the best voltage stability.Warning!Never apply AC power to the power cable of the FT-891, nor DC voltage greater than 15.8 Volts. When replacing the fuse, only use a 25-A fuse. Failure to observe these safety precautions will void the Limited Warranty on this product.r Before connecting the transceiver, check the voltage at the battery terminals while rev-ving the engine. If the voltage exceeds 15 Volts, adjust the vehicle’s voltage regulator before proceeding with installation.r Connect the RED power cable lead to the POSITIVE (+) battery terminal, and the BLACK power cable lead to the NEGATIVE (–) terminal. If you need to extend the power cable, use #12 AWG or larger insulated, stranded copper wire. Solder the splice connections carefully, and wrap the connections thoroughly with insulating electrical tape.r Before connecting the cable to the transceiver, verify the voltage and polarity at the voltage at the transceiver end of the DC cable, using a DC voltmeter. Now connect the transceiver to the DC cable.Warning!• Do not use a DC power supply cable other than the one that is supplied or specified. • Do not place anything on the DC power supply cable or step on it.• Do not use the DC power supply cable with the fuse holder cut off.• Do not reverse the polarity (positive and negative) when connecting the battery.Application for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50
7InstallationFT-891 Operating ManualGroundingThe provision of an effective ground system is important in any successful communica-tions station. A good ground system can contribute to station efficiency in a number of ways:r It can minimize the possibility of electrical shock to the operator.r It can minimize RF currents flowing on the shield of the coaxial cable and the chassis of the transceiver which may cause interference to nearby home entertainment devices or laboratory test equipment.r It can minimize the possibility of erratic transceiver operation caused by RF feedback or improper current flow through logic devices.An effective earth ground system may take several forms; for a more complete discus-sion,see an appropriate RF engineering text. The information presented below is intend-ed only as a guideline.Inspect the ground system – inside the station as well as outside – on a regular basis so as to ensure maximum performance and safety.Mobile Station GroundingAlthough satisfactory grounding in most installations will be achieved via the DC cable’s negative lead and the antenna system’s coaxial cable shield, it is often recommended that you provide a direct ground connection to the vehicle chassis at the mounting lo-cation of the transceiver. Due to unexpected resonances which may naturally occur in any location, improper communication system performance may result from insufficient grounding. These symptoms may include:r RF feedback (resulting in distortion on your transmitted signal);r Unintended frequency change;r Blinking or blanking of the frequency display;r Noise pickup; and/orr Loss of memory.Note that these conditions may occur in any communications installation. The FT-891 includes extensive filtering designed to minimize the chance of such problems; howev-er,random currents set up by insufficient RF grounding can nullify such filtering. Bonding the FT-891 transceiver to the vehicle or vessel’s ground system should clear up any such difficulties.Yaesu Musen does not recommend the use of “on glass” mobile antennas unless the shield of the coaxial cable is securely grounded near the feedpoint of the antenna. Such antennas frequently are responsible for the ground-related difficulties described above.Application for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50
8InstallationFT-891 Operating ManualBase Station Earth GroundingTypically, the ground connection consists of one or more copper-clad steel rods, driven into the ground. If multiple ground rods are used, they should be configured in a “V” configuration, and bonded together at the apex of the “V” which is nearest the station location. Use a heavy, braided cable (such as the discarded shield from type RG-213 coaxial cable) and strong cable clamps to secure the braided cables to the ground rods. Be sure to weather-proof the connections to ensure many years of reliable service. Use the same type of heavy,braided cable for the connections to the station ground bus (de-scribed below).Do not use gas line pipes in an attempt to provide a ground connection! To do so creates a serious risk of explosion!!Inside the station, a common ground bus consisting of a copper pipe of at least 1” (25 mm) diameter should be used. An alternative station ground bus may consist of a wide copperplate (single-sided circuit board material is ideal) secured to the bottom of the op-erating desk. Grounding connections from individual devices such as transceivers, power supplies,and data communications devices should be made directly to the ground bus using a heavy,braided cable.Do not make ground connections from one electrical device to another, and thence to the ground bus. This so-called “Daisy Chain” grounding technique may nullify any attempt at effective radio frequency grounding. See the drawings below for examples of proper and improper ground connections.Improper Ground ConnectionTransceiver“Daisy Chain”GNDGND GNDLinearAmplifierPowerSupplyProper Ground ConnectionTransceiverGNDGND GNDLinearAmplifierPowerSupplyApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50
9InstallationFT-891 Operating ManualRF FIELD EXPOSUREThis transceiver is capable of power output in excess of 100 Watts, so customers in the United States may be required to demonstrate compliance with Federal Communica-tions Commission (FCC) regulations concerning maximum permissible exposure to radio frequency energy. Compliance is based on the actual power output used, feedline loss, antenna type and height, and other factors which can only be evaluated as a system.Information regarding these regulations may be available from your Dealer, your local radio club, from the FCC directly (press releases and other information can be found on the FCC’s site on the World Wide Web at <http://www.fcc.gov>), or from the American Radio Relay League, Inc. (225 Main St., Newington CT 06111 or <http://www.arrl.org>).Although there is negligible radio frequency (RF) leakage from the FT-891 transceiver it-self, its antenna system should be located as far away from humans and animals as prac-ticable, so as to avoid the possibility of shock due to accidental contact with the antenna or excessive long-term exposure to RF energy. During mobile operation, do not transmit if someone is standing adjacent to your antenna, and use the lowest power possible.Application for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50

15Basic OperationFT-891 Operating ManualAdjusting the RF Gain and SquelchThe RF/SQL Gain control is configured differently, depending on the country to which the FT-891 has been exported. In the U.S. version, the default function of this control is “RF Gain.” The configuration of the RF/SQL Gain control is set via Menu Mode “No 05-05 [RF/SQL VR]”. If your transceiver is configured for “RF Gain” use, rotating this control fully clockwise in the SSB/CW modes will provide best sensitivity. To reduce the receiver’s RF Gain somewhat, rotate this control counter-clockwise slightly. You will observe an increasing number of bars on the S-meter as you rotate the RF Gain control counter-clockwise; this indicates increasing AGC voltage, which is causing the front-end gain to be reduced. In the FM mode, with “RF Gain” selected, the FT-891 goes into an “Auto Squelch” mode, with the Squelch level being preset at the factory. If this control is configured for “SQL” operation, the FT-891’s RF Gain will be set for maximum sensitivity in all modes, and the RF/SQL Gain control will function solely as a Squelch control. In this case, rotate the RF/SQL Gain control to the point where the back-ground noise is just silenced; this will provide the best sensitivity to weak signals, while keeping the receiver quiet when no signal is received. The LED just left side the display will glow Green when the squelch is opened by an incoming signal or noise.Setting the Operating FrequencyRotate the DIAL knob to set the frequency. Clockwise rotation of the DIAL increases the operating frequency.Application for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50

17Basic OperationFT-891 Operating ManualClarifier (Receiver Incremental Tuning)The [CLAR] key and MULTI knob are used to offset the receive frequency, the transmit frequency, or both, from their settings on the VFO-A frequency. Four small numbers on the Display show the current Clarifier offset. The Clarifier controls on the FT-891 are designed to allow setting a preset offset (up to ±9.99 kHz) without actually re-tuning, and then to activate it via the Clarifier [CLAR] key. This feature is ideal for following a drifting station, or for setting the small frequency offsets sometimes utilized in DX “Split” work.Here is the technique for utilizing the Clarifier:1. Press the [CLAR] key. The programmed off-set will be applied to the receive frequency.2. Press the MULTI knob, then rotation of the MULTI knob will allow you to modify your initial offset on the fly. Offsets of up to ±9.99 kHz may be set using the Clarifier.3. To cancel Clarifier operation, press the [CLAR] key.Note: Turning the Clarifier off merely cancels the application of the programmed offset from the receive and/or the transmit frequencies. To clear the Clarifier offset, and reset it to “zero,” press and hold the [CLAR] key.Application for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50
