tor latch. 2. You may position the microphone cable so as to cause it to exit from the side or the bottom of the transceiver. Just route the cable into the appropriate channel provided, as shown in the illustration. 3. Connect the Control cable between the Front Panel and Transceiver Body. 4. Install the Front Panel by sliding it into the position shown; you will hear a click when the panel locks into place. 5. To remove the Front Panel, use your left thumb to push rearward (slightly) the latch on the left-hand of the panel, then slide the Front Panel to the right and away from the transceiver. 5 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Installation Power connection The 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 vehicles 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 vehicles 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 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 specified. battery. 6 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Installation Grounding The 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 Grounding Although satisfactory grounding in most installations will be achieved via the DC cables negative lead and the antenna systems 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/or r 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 vessels 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. 7 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Installation Base Station Earth Grounding Typically, 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 Connection Proper Ground Connection Transceiver GND Linear Amplifier GND Power Supply GND Transceiver GND Linear Amplifier GND Power Supply GND Daisy Chain 8 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Installation RF FIELD EXPOSURE This 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 FCCs 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. 9 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Front Panel Controls & Switches RF/SQL knob This (outer) SQL/RF knob adjusts the gain of the receivers RF and IF stages.

ing level. 14 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Basic Operation Adjusting the RF Gain and Squelch The 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 receivers 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-891s 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 Frequency Rotate the DIAL knob to set the frequency. Clockwise rotation of the DIAL increases the operating frequency. 15 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Basic Operation Operation on 60-Meter (5 MHz) Band (U.S. Version Only) The recently-released 60-meter band is covered, in the FT-891, by fixed memory chan-

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. 17 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Advanced Operation IF SHIFT The receivers IF SHIFT feature is an effective interference-reduction tool, which allows you to shift the passband response higher or lower without changing the pitch of the incoming signal. 1.

To turn off the DSP Noise Reduction feature, press the [A](DNR) key again. 6. If noise is present at a level which causes indication on the S-meter, the performance of the Noise Reduction filter may be enhanced by rotating the SQL/RF (RF Gain) con-

trol in a counter-clockwise direction so as to set the (fixed) S-meter reading at the same level as the noise peaks. This adjustment raises the AGC threshold of the receiver. 20 FT-891 Operating ManualApplication for FCC / IC FCC ID: K6620651X50 / IC: 511B-20651X50 Advanced Operation Notch Filter The DSP systems Notch Filter may be helpful in removing one or more offending carrier or heterodyne signals from the audio passband. 1.
