13.8 Volts DC (±IO%), and capable of at least 22 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. For base station installations, Yaesu recommends the use of the FP-I 023, FP-I 025, or FP- 1 030A AC power supplies. Other models of power supplies may be used with the FT -100, but the 13.8V DC input voltage, 22-Ampere current capability, and DC cable polarity guidelines described above must be strictly followed. Note that other manufacturers may use the same type of DC power connections as does your FT-IOO transceiver, but the wiring configuration of the other manufacturer's plug may be different from that specified for your transceiver. Serious damage can be caused if improper DC connections are made; consult with a qualified service technician when in doubt. 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. Tips for Successful Mobile Installations: o Before connecting the DC cable to the battery, measure the voltage across the battery terminals with the engine running fast enough to show a charge. If the voltage is above 15 Volts, the vehicle's voltage regulator should be adjusted to reduce the charging voltage to 14 Volts or lower. o Route the DC cable as far away from the ignition cables as possible. o If the DC cable is not long enough, use #12 AWG (minimum) stranded, insulated wire to extend it. Be certain to solder the connections at the splice securely, and provide ample insulation for the soldered splice (heat shrink tubing plus black electrical tape work well). o Check the battery terminal connections frequently to be sure they are tight and not corroded. ,--------------- Caution ---------------, Permanent damage can result if improper supply voltage, or reverse-polarity volt- age, is applied to the FT-IOO. The Limited Warranty on this transceiver does not cover damage caused by application of AC voltage, reversed polarity DC, or DC voltage outside the specified range of 13 .8V ± I 0%. Never attempt to connect the FT-JOO to a 24 Volt battery system. 8 When replacing fuses, be certain to use a fuse of the proper rating. The FT -100 requires a 25A fast-blow fuse.

tions station. A good ground system can contribute to station efficiency in a number of ways: D It can minimize the possibility of electrical shock to the operator. D 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 entertain- ment devices or laboratory test equipment. D It can minimize the possibility of erratic transceiver operation caused by RF feed- back or improper current flow through logic devices. An effective earth ground system may take several forms; for a more complete discussion, see an appropriate RF engineering text. The information presented below is intended 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 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 location of the transceiver (installation using the MMB-48 Mobile Bracket will accomplish this, if the MMB-48 itself is mounted to the vehicle's chassis). Due to unexpected resonances which may naturally occur in any location, improper communication system performance may result from insufficient grounding. These symptoms may include: D RF feedback (resulting in distortion on your transmitted signal); D Unintended frequency change; D Blinking or blanking of the frequency display; D Noise pickUp; and/or D Loss of memory. Note that these conditions may occur in any communications installation. The FT-JOO includes extensive filtering designed to minimize the chance of such problems; however, random currents set up by insufficient RF grounding can nullity such filtering. Bonding the rear panel Ground lug of the FT-J 00 transceiver to the vehicle or vessel's ground system should clear up any such difficulties. Yaesu 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 fre- quently are responsible for the ground-related difficulties described above. 10 FT-100 MICRO MOBILE OPERATING MANUAL

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 loca- tion. 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 weatherproof 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 (described 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 25 mm (1") diameter should be used. An alternative station ground bus may consist of a wide copper plate (single-sided circuit board material is ideal) secured to the bottom of the operating desk. Grounding connections from individual devices such as transceivers, power sup- plies, 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. If your coaxial cable does not connect directly to the station ground bus, you may connect a ground cable to the FT-J 00 using one ofthe mounting bolts from the MMB-48 Mobile Bracket.

tant in ensuring successful communications. The FT-IOO is designed for use with any an- tenna system providing a son resistive impedance at the desired operating frequency. While minor excursions from the son specification are of no consequence, the power amplifier's protection circuitry will begin to reduce the power output of there is more than a 50% divergence from the specified impedance (less than 33n or greater than 75n, corre- sponding to a Standing Wave Ratio (SWR) of 1.5: 1). Two antenna connector "pigtails" are provided on the rear panel of the FT -100. The "AN- TENNA 1" connection is used for HF and 50 MHz, while the "ANTENNA 2" connector is used for 144 MHz and 430 MHz. Guidelines for successful base and mobile station installations are shown below. Mobile Antenna Installations Mobile antennas for the HF bands, with the possible exception of those designed for 28 MHz, display very high "Q" due to the fact that they must be physically shortened, then resonated using a loading coil. Additional system bandwidth may be realized using the Yaesu FC-20 Automatic Antenna Tuner, which will present a son impedance to your transceiver on the 1.8 ~ 50 MHz bands so long as the SWR on the coaxial line connected to the FC-20 is below 3: 1. On the VHF and UHF bands, coaxial line losses increase so rapidly in the presence of SWR that we recommend that all impedance matching to son be performed at the antenna feedpoint. Yaesu's Active-Tuned Antenna System (ATAS-100) is a unique HFIVHF/UHF mobile antenna system, which provides automatic tuning when used with the FT-IOO. See page 62 for full details on the ATAS-100. For VHF/UHF weak-signal (CW/SSB) operation, remember that the antenna polarization standard for these modes is horizontal, not vertical, so you must use a loop or otherwise horizontally-polarized antenna so as to avoid cross-polarization loss of signal strength (which can be 20 dB or more!). On HF, signals propagated via the ionosphere develop mixed polarizations, so antenna selection may be made strictly on mechanical consider- ations; vertical antennas are almost always utilized on HF for this reason. 12 FT-100 MICRO MOBILE OPERATING MANUAL

When installing a "balanced" antenna such as a Vagi or dipole, remember that the FT -100 is designed for use with an (unbalanced) coaxial feedline. Always use a balun or other balancing device so as to ensure proper antenna system performance. Use high-quality son coaxial cable for the lead-in to your FT- 100 transceiver. All efforts at providing an efficient antenna system will be wasted if poor quality, lossy coaxial cable is used. Losses in coaxial lines increase as the frequency increases, so a coaxial line with 0.5 dB ofloss at 7 MHz may have 6 dB ofloss at 432 MHz (thereby consuming 75% of your transceiver's power output!). As a general rule, smaller-diameter coaxial cables tend to have higher losses than larger-diameter cables, although the precise differences depend on the cable construction, materials, and the quality of the connectors used with the cable. See the cable manufacturers' specifications for details. For reference, the chart below shows approximate loss figures for typically- available coaxial cables frequently used in HF installations. Loss in dB per 30m (100 feet) for Selected 50n Coaxial Cables To 144 MHz 1430 MHz Antenna Loss figures are approximate; consult cable manufacturer's catalogs for complete specifica- tions.

in the event of a catastrophic support or power-pole structural failure. Ground your anten- nas' support structure(s) adequately, so as to dissipate energy absorbed during a lightning strike. Install appropriate lightning arrestors in the antenna coaxial cables (and rotator cables, if rotary antennas are used). In the event of an approaching electrical storm, disconnect all antenna lead-in, rotator cables, and power cables completely from your station if the storm is not immediately in your area. Do not allow disconnected cables to touch the case of your FT-IOO transceiver or accessories, as lightning can easily jump from the cable to the circuitry of your trans- ceiver via the case, causing irreparable damage. If a lightning storm is in progress in your immediate area, do not attempt to disconnect the cables, as you could be killed instantly if lightning should strike your antenna structure or a nearby power line. If a vertical antenna is utilized, be certain that humans and/or pets and farm animals are kept away both from the radiating element (to prevent electrical shock and RF exposure danger) and the ground system (in the event of an electrical storm). The buried radials of a ground-mounted vertical antenna can carry lethal voltages outward from the center of the antenna in the event of a direct lightning strike.

This transceiver is capable of power output in excess of 50 Watts, so customers in the United States may be required to demonstrate compliance with Federal Communications Commission (FCC) regulations concerning maximum permissible exposure to radio fre- quency energy. Compliance is based on the actual power output used, feedline loss, an- tenna 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 ), or from the American Radio Relay League, Inc. (225 Main St., Newington CT 06111 or ). Although there is negligible radio frequency (RF) leakage from the FT -100 transceiver itself, 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. Never stand in front of an antenna (during testing or operation) when RF power is applied, especially in the case of 430 MHz directional arrays. The 20 Watt power output supplied by the FT -100, combined with the directivity of a beam antenna, can cause immediate heating of human or animal tissues, and may cause other undesirable medical effects. 16 FT-100 MICRO MOBILE OPERATING MANUAL

sories, you may need to experiment with grounding and/or Radio Frequency Interference (RFI) suppression devices (such as ferrite cores) to minimize interference to your commu- nications caused by energy from the computer. Computer-generated RFI is usually a result of inadequate shielding of the computer's cabinet or 110 and peripheral connections. While computer equipment may "comply" with RF emission standards, this does not ensure that sensitive Amateur Radio receivers like the FT -100 will not experience interference from the device! Be certain to use only shielded cables for TNC-to-Transceiver connections. You may need to install AC line filters on the power cord(s) of the suspected equipment, and decoupling ferrite toroidal chokes may be required on interconnecting patch/data cables. As a last resort, you can try installing additional shielding within the computer's case, using appro- priate conductive mesh or conductive shielding tape. Especially check "RF holes" where plastic is used for cabinet front panels. For further information, consult amateur radio reference guides and publications relating to RFI suppression techniques. HEAT AND VENTILATION To ensure long life of the components, be certain to provide adequate ventilation around the cabinet of the FT-IOO. The cooling system of the transceiver must be free to draw cool air in from the side of the transceiver and expel warm air from the rear of the transceiver. Do not install the transceiver on top of another heat-generating device (such as a linear amplifier), and do not place equipment, books, or papers on top of the transceiver. Place the transceiver on a hard, flat, stable surface. Avoid heating vents and window locations that could expose the transceiver to excessive direct sunlight, especially in hot climates.

whether you're at home or away. Due to the compact size of the FT-IOO, many of the rear- panel connectors are used for more than one purpose. The sections to follow will describe the interfacing procedures. Linear Amplifier Interfacing The FT -100 provides the switching and drive-control lines required for easy interfacing to most all commonly-available amplifiers sold today. These include: o The Antenna Cable Pigtails (#1 and #2); o A T/R control line (open circuit on RX, closure to ground on TX); and o A negative-going ALC jack (control voltage range: OV to -4 V DC). o When interfacing to the VL-I 000 Solid State 1 K W Linear Amplifier, the optional CT -58 Interface Cable provides for easy interconnection. The rear-panel ACC jack is a miniature stereo type, which accepts ALC control voltage input on the tip connection, and T/R control on the ring connection. The main shaft is used for the ground connection. Typical amplifier interface circuits are shown below. Note that some amplifiers, particularly VHF or UHF "brick" amplifiers, offer two methods ofT/R switching: application of + 13V or a closure to ground. Be sure to configure your amplifier so that it switches via a closure to ground, as provided by your FT -100. Alternatively, many of these amplifiers use "RF Sensing" to control their relays; if yours is not in this category, you may then use the T/R control line from the ring of the ACC jack for control of your HF linear amplifier, if desired. The T/R control line is a transistor "open collector" circuit, capable of handling positive amplifier relay coil voltages of up to +50V DC and current of up to 400 rnA. If you plan on using multiple linear amplifiers for different bands, you must provide external band-switch- ing of the "LIN Tx" relay control line from the "ring" connection of the ACC jack 18 Important Note! Do not exceed the maximum voltage or current ratings for the ACC jack. This jack is not compatible with negative DC voltages, nor AC voltages of any magnitude. Most amplifier control relay systems require only low DC voltage/current switch- ing capability (typically, + 12V DC at 25 ~ 75 rnA), and the switching transistor in the FT -100 will easily accommodate such amplifiers.

G..r--:n_.i:&JP:===:!) CT-58 ALC Cable Installation When operateing the FT-100 with the VL-1 000 Solid State 1 KW Lin- ear Amplifier, change the internal connections of the FT-100, as shown below. This connection matches the "LINEAR" configuration shown on Page 4. Bottom Side FT-100 MICRO MOBILE OPERATING MANUAL 19 all-guide s.com

The FT-100 is easy to connect to most all Terminal Node Controllers (TNCs) or other digital modem units used for RTTY, HF Packet, and other digital modes which utilize USB or LSB as the fundamental operating mode. Audio Frequency-Shifted Keying (AFSK) operation for HF Baudot, AMTOR, 300 bps Packet, etc. is provided via the rear-panel DATA jack. Pin 1 of this jack accepts AFSK input from the TNC's "TX Audio" line. Pin 3 is used for PTT control (the TNC closes this line to ground to cause the FT -100 to transmit). Pin S is used for "RX Audio" which is sent to the TNC for decoding. Pin 2 is used for Ground for all lines. The optimum levels/impedances are shown below: Pin 1 (Data In): 40 mV@ 10 kQ Pin S (Data Out): 300 m V @ 10 kQ When operating on AFSK, the microphone is automatically disconnected when the radio's microprocessor detects PTT control from the DATA jack. Therefore, it is not necessary to disconnect the microphone during digital mode operation. Typical interconnection information is presented below. For operation on RTTY, HF Packet, etc., several Menu selections must be set appropri- ately. These include: MENU #21 (HF TX PO): MENU #28 (AFSK LEVEL): MENU #34 (AFSK MODE): MENU #35 (RTTY SHIFT): MENU #36 (RTTY DISPL V): Set to SOW after adjusting AFSK Level (see page 88) Set for 4 "dots" of ALC indication (see page 89) Set for desired mode Set to match shift set in your TNC Set for offset or non-offset frequency display Details regarding these and other MENU settings may be found beginning on page 82.

The rear-panel DATA jack is also used for connections to a TNC for FM Packet work. The FM Packet connections are in accordance with a standard adopted by many Amateur- product manufacturers. However, we recommend that you verify the connections to any cable you may already own by comparing it to the pictorial below. The FT-lOO's DATA jack connections are optimized for the data transmission and recep- tion speed in use. In accordance with the aforementioned industry standards, the signal levels, impedances, and bandwidths are significantly different on 9600 bps as opposed to 1200 bps. If your TNC does not provide multiple lines to accommodate such optimization, you may still be able to utilize your TNC if it is designed for multiple-radio use; connect the TNC "Radio 1" port to the 1200 bps lines on the FT -100, and the "Radio 2" port to the 9600 bps lines. For ease in making connections to your packet TNC, the optional CT -39 Packet Cable is avail- able from your Yaesu dealer. With reference to the "DATA Jack Pin Connections" chart and the DATA jack pinout on page 4, you may con- nect your TNC in minutes using the color-coded information provided. Most modem TNCs use a PLL-type DCD (Data Carrier Detect) circuit, so you will generally not need to connect anything to the Squelch Con- trolline (Pin 6) ofthe DATAjack.

the Packet Data Input level (set via a potentiometer inside the TNC) must be adjusted to provide a deviation of ±2.75 kHz (±0.25 kHz). Check with your packet node's sysop if you have any questions about the appropriate deviation level for your network. The setting of the 1200 bps Packet Data Input level is much less critical, and satisfac- tory adjustment to the optimum (±2.5 - ±3.5 kHz) deviation can usually be done "by ear" by adjusting the TNC's 1200 bps TX Audio Level potentiometer so that the outgoing packets (as monitored on a separate VHF or UHF receiver) are slightly lower than the level of your speech. If you have the optional MH-368SJS DTMF Microphone, set your TNC's tone output to be about the same level as that of the DTMF tones produced by the MH- 368SJS. The "RX 1200" and "RX 9600" lines are fixed-level audio outputs, not affected by the setting of the AF (GAIN) control. CW Key/Keyer Connections All commonly-available keyer paddles should work perfectly with the built-in Electronic Keyer. The wiring configuration for the paddle is shown below. For straight-key operation, only the tip and shaft connections are used. Note: Even when using a straight key, you must use a three- conductor ("stereo ") plug. If a two-conductor plug is used, the key line will be constantly shorted to ground When using an external electronic keyer, be absolutely cer- tain that it is configured for "positive" keying, not "negative" or "grid block" keying. The "key-up" voltage of the FT-J 00 is +5V, and the "key-down" current is only about I rnA. For CW automated keying using a personal computer, with an external memory keyer providing for manual sending, it usu- ally is possible to connect the keyed lines together via a "Y" connector. Check with the documentation accompanying your keyer and your contest/DX software for any cautions which need to be observed. 22 FT-IOO MICRO MOBILE OPERATING MANUAL

Connection of a tape recorder, WeatherFax demodulator, or other such receiver accessory is easily accomplished by using the DATA jack's DATA OUT (1200 bps) terminal (Pin 5) and Ground (Pin 2). The audio output is fixed at 100 mY, with an impedance of600 O. CONNECTION OF HEADPHONES The FT -1 OO's extremely compact size does not permit inclusion of a headphone jack. Direct connection of 40 or SO headphones to the Speaker jack, however, could cause hearing damage, due to the high level of audio output available at that jack. To connect headphones to the Speaker jack, build a small attenuator circuit into a small adapter box. Connect a lOon y, W resistor in series with the headphone line, and a Ion Y,W resistor shunt to the shield (ground). ADJUSTING THE FRONT FEET The two front feet of the transceiver allow the trans- ceiver to be tilted upward for better viewing. Sim- ply fold both feet forward to raise the front of the transceiver, and fold them back against the bottom case to lower the front of the FT -100. FT-100 MICRO MOBILE OPERATING MANUAL 23

~ _ features of the FT-IOO.I know you're anxious to get on the air, but I encour- ~ ~ . age you to read the "Operation" section of this manual as thoroughly as possible, so you'll get the most out of this fantastic new transceiver. Now ... let's get operating! BEFORE You START 1. Be certain that power supply connections have been securely made, and that the proper polarity has been observed. 2. Be certain that your antennas have been connected to the correct cable pigtails on the rear of the transceiver. OPERATION QUICK START The basic steps required to begin operation are: 1. Tum the transceiver on. 2. Set the band on which you wish to operate. 3. Set the operating mode on which you wish to operate. 4. Adjust the audio volume level. 5. Adjust the operating frequency using the MAIN DIAL. TURNING THE TRANSCEIVER ON AND OFF 1. To tum the FT-IOO on, press and hold in the PWR switch for Yz second. 2. To tum the transceiver off, again press and hold in the PWR switch for Yz second.

Before you explore these features, it is important to understand the proper utilization of the OPERATING FUNCTION SELECTOR" key ([FUNCD and the [A], [B], [C], and [0] keys, which often are used to activate or change various features of the FT -100 in everyday operation. OPERATING FUNCTION SELECTOR ([FUNC] KEY) FulI access to the many fulI range offeatures provided on the FT -100 would require many more controls and switches than could possibly fit on the tiny front panel of the transceiver. Therefore, the FT-IOO utilizes a flexible OPERATING FUNCTION SELECTOR key, labeled [FUNC], to provide access to these many features via the [A], [B], [C], and [0] keys. The [FUNC] key must be pressed correctly, as there are two modes of [FUNC] key opera- tion which are often used. o Pressing the [FUNC] key momentarily causes this key to serve as the OPERATING FUNCTION SELECTOR. o Pressing and holding in the [FUNC] key for Y, second activates the "MENU" mode, used to customize many aspects of the transceiver's configuration. The MENU mode is detailed in the chapter beginning on page 82. Basic Operation Of the [FUNC] Key 1. Press the [FUNC] key momentarily. Note that the labels on the LCD just above the [A] ~ [0] keys will change. Repeatedly pressing the [FUNC] key wilI scroll the LCD through the nine rows of features provided via the OPERUING FllNCTlON SELECTOR. 2. Once the row containing the desired feature is located, press the [A], [B], [C], or [0] key to select the desired function within that row. 3. Next, depending on the feature being utilized, you may be instructed to press the same key again to toggle the current setting to a new state (e.g. from OFF to ON). If you don't see the operating functions appear on the LCD, you may have held the IFUNCI key in too long - putting you in the "Mnvu" mode. Press IFUNCI again to escape and start over. ICON DISPLAY The left side of the FT-J ~O's LCD includes a handy [con display field, which alerts you to many aspects of the transceiver's current operating status. 34 FT-JOO MICRO MOBILE OPERATING MANUAL all-guide s.com

I. Press the [FUNC] key, as necessary, until Operating Function Row 6 [S.O, 2.4, 500, 300] appears on the display. 2. Now press the [A](S.O) key to select 6.0 kHz, the [B](2.4) key to select 2.4 kHz, the [C](500) key to select SOO Hz, or the [D](300) key to select 300 Hz bandwidth. These bandwidth selection options are displayed immediately above the [A], [B], [C], and [D] keys along the bottom edge of the display. Note that the [B] bandwidth (2.4 kHz) is installed at the factory, while the other bandwidths require the installation of optional filters. It' '.; Only the 6.0 kHz and 2.4 kHz modes are usable for AM reception, as the 500 ~ _ Hz and 300 Hz bandwidths are much too narrow to pass AM signals. ~, FREQUENCY SYNTHESIZER STEPS The FT-I 00 uses a "frequency synthesizer" tuning system, which is capable of both coarse and ultra-fine steps. A wide variety of synthesizer steps is available, so allow you the flexibility to cope with different operating situations. The tuning steps will change as you change operating modes. This capability provides greater convenience during frequency adjustments, as the need for tuning precision is very different when operating on CW or D1G(AFSK) as compared to FM. Press the [STEP] key momentarily to change the tuning steps of the MAIN DIAL and/or the SELECT knob. [n the case of the MAIN DIAL, the [STEP] key toggles only the tuning steps utilized in the SSB, CW, and D1G(AFSK) modes: 1.25 -7 2.5 -7 S -7 10 -7 2S -7 SO -7 100 -7 1.25 ... (Hz) (The AM/FM steps are fixed at 100 Hz/step in AM/FM, I kHz/step in W-FM) [n the SSB/CW mode, press and hold the [STEP] key for Yz second to change the tuning steps of the MAIN DIAL is fixed at I kHz/step. [n the case ofthe SELECT knob. the [STEP] key toggles only the tuning steps in the AM and FM modes, with SSB/CW/D[G being fixed at 10 kHz per step: AM: I k -7 5k -7 9k -7 10k -7 12.5k -7 2Sk -7 I k ... (Hz) FM: 5k -7 10k -7 12.Sk -7 ISk -7 20k -7 25k -7 SOk -7 S k ... (Hz) FM-W: 50k -7 lOOk -7 SOk ... (Hz) Finally, some preset values for the operation of the SELECT knob are also available. These are especially useful for quick frequency change. FT-JOO MICRO MOBILE OPERATING MANUAL 35

The rate at which the MAIN DIAL causes frequency change is determined, in part, by the number of "steps" per revolution of the dial. The stepping rate may be doubled (or cut in half) via the following procedure: 1. Press and hold in the [FUNC] key for Y:z second to activate the "Menu" command mode. 2. Rotate the SELECT knob until MENU #01 is found. 3. Rotate the MAIN DIAL to choose the desired tuning speed. The default value is "200," and selecting" 1 00" will cut the tuning rate in half. 4. Press the [FUNC] key momentarily to save your new setting and exit to normal opera- tion. It' ...

Now press the [A](A/B) key (the AlB function) to toggle between the "A" and "B" VFO on the band on which you are currently operating. There are two such VFOs provided on each Amateur band, so you may set VFO-A to the CW sub-band, and VFO-B to the SSB sub-band, if you like. The operating mode will be preserved, along with the frequency information, on each VFO. MICROPHONE: PROGRAMMABLE FUNCTION BUTTONS The MH-36SSJS and MH-42sSJS microphones include three programmable buttons, la- beled P, P1, and P2. These buttons may be used for quick access to frequency control commands of the FT -100. In the default configuration, the P button controls VFO/MR (Memory Recall); P1 controls Band Down, while P2 controls Band Up. The configuration of these buttons can be changed via the MENU system: I. Press and hold in the [FUNC] key for 1;j second to enter the MENU mode. 2. Rotate the SELECT knob to recall MENU #59 (MIC SW SET). 3. Rotate the MAIN DIAL to choose from the following configuration options: 4. When you have made your selection, press the [FUNC] key momentarily to save the new setting and exit to normal operation.

Section 97.40I(d) of the regulations governing amateur radio in the United States permit emergency amateur communications on the spot frequency of 5167.5 kHz by stations in (or within 92.6 km of) the state of Alaska. This frequency is only to be used when the immediate safety of human life and/or property are threatened, and is never to be used for routine communications. The FT -100 includes the capability for transmission and reception on 5167.5 kHz under such emergency conditions via the Menu system. To activate this feature: Q) Press and hold in the [FUNC] button for Y:! second to activate the MENU mode of operation. ~ Rotate the SELECT knob to select MENU #66 (5167.5 kHz). Q) Rotate the MAIN DIAL to select "ON" for this feature. ® Press the [FUNC] key momentarily exit the MENU mode. Emergency communication on this spot frequency is now possible: Rotate the SELECT in the MR mode, as necessary, to locate the Emergency Channel, which will be located between the Memory channel 300 and DUP 001. Note that the receive-mode CLARIFIER functions normally while using this frequency, but variation of the transmit frequency is not possible. Activation of MENU #66 does not enable any other out-of-amateur-band capability on the transceiver. The full specifications ofthe FT -100 are not necessarily guaranteed on this frequency, but power output and receiver sensitivity should be fully satisfactory for the purpose of emergency communication. To return to normal transceiver operation, just press the [VFO/MR] key, which will cause you to switch to one of the VFOs.

The optional ATAS-I 00 Active-Tuning Antenna System provides operation on a number of HF bands (7114/21128 MHz) plus 50 MHz, 144 MHz, and 430 MHz. The FT -100 pro- vides microprocessor control of the tuning mechanism in the AT AS-I 00 for convenient automatic tuning. Before operation can begin, you must instruct the FT -I OO's microprocessor that the ATAS- 100 is being used. This is done using the MENU:

MANUAL TUNING In some instances, the SWR may be slightly improved by manual adjustment of the an- tenna position. This may be needed for operation on bands like 17 meters, where the "Q" of the ATAS-IOO is high, causing a narrow resonance range. Before Manual Tuning, press the [FUNC] key, as needed, to recall Operating Function Row 7 [MTR, TUN, PRO, VOX], then press the [A](MTR) key to change the ALe meter to the SWR meter ("MTR" icon will become Bold). To tune the ATAS-IOO manually, press and hold in the microphone PTT switch. With the transceiver in the "Transmit" mode, press and hold in the [UP] key (to raise the antenna) or the [OWN] key (to lower the antenna). While you hold in one of these keys, the FT -100 will generate a carrier, and you may watch the top scale of the FT-I OO's meter, looking for the meter indication to reach its minimum value. When this is reached, release the [UP] or [OWN] key, then release the PTT key to return to the "Receive" mode. ~ change frequency by at least 10 kHz before attempting automatic match- It ~.. ..',; 0 Once automatic matching has been successfully accomplished, you must ~ ~ .. - ing again. Within a window of ±1 0 kHzfrom a match point, the transceiver 5 microprocessor will ignore any command to attempt automatic matching. o Antenna tuning is accomplished using a "CW" carrier, although the mode indica- tion will not change to "CW" (if you are operating on another mode) during an- tenna tuning. o If you see a "HI SWR" /con on the LCD, it may mean that there is a problem in your coaxial cable (bad connection, etc.) which is preventing ".: ." ··i"l .. f .><. successful tuning. Replace the cable, or try adding a few feet/meters of . cable (to eliminate the possibility of adverse "transformer action" in the ~::; td F~~ "HISWR" 50n cable during the tuning process). ICON o If you are able to achieve an SWR of less than 2: 1 via manual tuning, the FT-I00 will "accept" the manual setting, and you may then re-tune automatically when changing bands. o If, however, you stop manual tuning at a non-optimum setting (SWR >2: 1), the FT- 100 will not permitfurther automatic tuning. To refresh the setting of the ATAS-100, press the [OWN] key until the ATAS-100 will fully retract. You may then restart automatic tuning per the procedures described earlier. o Although the ATAS-100 is not specifiedfor use on the 10,18, and 24 MHz bands, it usually is possible to achieve a satisfactory SWR on these bands. Please feel free to experiment on these bands, if you like. FT-IOO MICRO MOBILE OPERATING MANUAL 63

ATAS-100 OPERATING TIPS The information below will help you derive the best performance possible from the ATAS- 100 Active-Tuning Antenna System. GROUNDING It is critically important that you establish a good mechanical and RF ground connection for your ATAS-I 00 (as with all vertical antennas). Mobile mounts which are bolted through the vehicle's roof, or otherwise mechanically affixed, will usually be satisfactory. How- ever, magnetic mounts do not provide the RF grounding necessary for good performance, and are not recommended for use with this antenna. TUNING PROCEDURE The feedpoint impedance of the ATAS-IOO (resistance and reactance) will necessarily vary over a wide range when you change bands. Occasionally, the transceiver's microprocessor will not initially be able to determine the proper direction for the ATAS-I 00 to travel (inward or outward) for best SWR. To resolve this situation, the transceiver will then command the ATAS-IOO to retract fully to its minimum height, and thence restart the tuning process. In this instance, the "TUN" icon will remain on the display after you press the [B](TUN) key. If this happens, do not press the [B](TUN) key repeatedly. The transceiver will remain in the receive mode as it retracts (this may take up to one minute). Thereafter, the transmitter will be engaged, and the ATAS-IOO will be automatically adjusted for best SWR. The "TUN" icon will then disappear from the LCD, and you will be ready for operation. The command which retracts the ATAS-I 00 to its minimum height utilizes a fixed timer. If the ATAS-I 00 reaches its minimum height before the timer has expired, you may observe the antenna's motor continuing to rotate; this is normal, as the ATAS-I ~O's retraction mecha- nism includes a clutch assembly to prevent damage to the antenna or motor. EXTERNAL WATTMETERS If you wish to use an external wattmeter in conjunction with the transceiver and your ATAS-IOO, please check the wattmeter with an Ohmmeter prior to installation. Be sure there is a direct connection between the "IN" and "OUT" jacks of the wattmeter (zero resis- tance), and also ensure that there is a completely open circuit between the center pin and shield of the wattmeter's output jack. Some wattmeters use a coil or other device which shorts the center pin to ground at DC, and this type of internal wattmeter circuitry will not allow the tuning function of the AT AS-I 00 to operate. 64 FT-100 MICRO MOBILE OPERATING MANUAL all-guide s.com

ATAS-100 OPERATING TIPS OPERATION ON 30/17/12 METERS Although the ATAS-J 00 is not specified for operation on the above bands, and optimum operation is therefore not guaranteed, the ATAS-IOO generally can be tuned successfully on these bands (some manual adjustment may be required). Operation of the ATAS-I 00 on these bands will not damage the antenna's components; please feel free to experiment on these bands, if you like. FT-JOO MICRO MOBILE OPERATING MANUAL 65

The optional FC-20 Automatic Antenna Tuner provides automatic tuning of a coaxial line so as to present a nominal50n impedance to the FT-IOO's HF!50 MHz antenna port. Before operation can begin, you must instruct the FT -1 ~O's microprocessor that the FC-20 is being used. This is done using the MENU: CD Press and hold in the [FUNC] key for Y:z second to activate the MENU mode.

ANTENNA TUNER MEMORY SYSTEM The FC-20, working in concert with the FT -100, 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 100 memories are provided: 11 of these are "general" memories apportioned one per band, while the remaining 89 are allocated for specific frequency data within the various bands, with the capability to resolve new tuning data every 10 kHz. A few guidelines should be noted regarding the FC-20's memory system: I. Tuning data is stored when you make an active effort to store it by pressing and holding in the [B](TUN) key for Y:, second. Although the tuner will automatically activate itself if it encounters more than 1.5: 1 SWR, this memory will not be stored unless you have pressed the [B](TUN) key for Y:, second. This allows you to store your favorite operat- ing frequency areas into tuner memory without tying up memory space with matching data on seldom-used frequencies. 2. If the FC-20 cannot resolve a satisfactory match because the SWR is above 3: 1 (2: 1 on the 50 MHz band), 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 [B](TUN) key again for Y2 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. 3. Another technique which may allow matching in some situations is to add a few feet or meters of coaxial cable on the "antenna side" of the FC-20. This will change the imped- ance transformation taking place in the coaxial cable, possibly moving the impedance presented to the FC-20 into an acceptable range. Note that this is not changing the actual antenna SWR, but only the impedance "seen" by the FC-20's matching circuits. 4. [fyour antenna system presents an SWR of less than 1.5: 1, you may wish to tum off the antenna tuner, as full transmitter power will be delivered to the antenna system without intervention by the FC-20. '::::1:::" 5. [fthe impedance encountered by the FC-20 exceeds 3: I, and the "HI SWR" ; " ... ' ! ....... . icon is illuminated, the microprocessor will not retain the tuning data for that frequency, as the FC-20 presumes that you will want to adjust or repair your ~::; td!?

The FT-IOO provides a wide variety of memory system resources. These include: o 300 "standard" memory channels, numbered "001" through "300." These memo- ries are partitioned into six Memory Groups, each holding up to 50 memory chan- nels. o Five QMB (Quick Memory Bank) channels, providing one-touch storage and recall of prime operating frequencies. The QMB channels are labeled "QMB 001" through "QMB 005." o 20 Split Frequency memory channels, used for storing frequency settings when the transmitter and receiver frequency are different. The Split channels are labeled "OUP 001" through "OUP 020." o Four "HOME" channels, for storage and quick recall of one prime frequency on each of the four band groupings: HF, 50 MHz, 144 MHz, and 430 MHz. These chan- nels are labeled "HOM 001" through "HOM 004." o 20 memory channels for the band-edge memories also known as "Programmable Memory Scan" channels, labeled "PGM 001" through "PGM 020." These memories do not just store away the operating frequency; thanks to the enhanced memory space provided in the FT-IOO, the following data will be stored into each memory channel: o Operating frequency o Operating mode (LSB, USB, CW, etc.) o Receiving filter bandwidth o Memory Channel "Skip" status o IPO status o ATT status o Repeater Shift information o Repeater CTCSS tone or DCS information Storage and recall of memory channels in the various memory systems is quite straightfor- ward, thanks to the advanced ergonomic design of the FT-I 00. These procedures are de- tailed below. 68 FT-JOO MICRO MOBILE OPERATING MANUAL

The Smart Search™ feature automatically stores frequencies where activity is encountered on the current band. When Smart Search™ is engaged, the transceiver quickly searches above and below your current frequency, storing active frequencies as it goes (without stopping on them even momentarily). These frequencies are stored in a special Smart Search™ memory bank, consisting of 40 memories (20 above the current frequency, 20 below the current frequency). This feature available on the FM and AM modes. This fea- ture is especially helpful when traveling, as you can instantly store active FM repeater frequencies without having to look up the frequencies in a reference book. I. Set the SQl knob to the point where background noise is silenced. A typical setting, for effective Smart Search™ operation, will be at 12 o'clock or slightly clockwise from this position. 2.

VFO mode or one of the memory modes, scanning operation is fundamentally identical in all configurations, but with the following differences: o In the VFO mode, scanning causes the transceiver to sweep up or down the band, pausing or halting on any signal encountered; o In the QMB mode, the scanner will scan only the QMB memory bank; o In the Memory mode, the scanner will scan the programmed memories, and can be instructed to skip certain memories during scanning; o In the Programmable Memory Scan (PMS) mode, the scanner will scan the band within user-programmed frequency limits. SCANNING OPERATION 1. Set the SQL knob to the point where background noise is silenced. A typical setting, for effective scanning operation, will be at 12 o'clock or slightly clockwise from this position. 2. Set the transceiver into the operating configuration in which you wish to scan (VFO, Memory, QMB, etc.). 3. Press the [FUNC] key, as needed, to recall Operating Function Row 4 [SKP, SCN, OW, SCH], then press and hold the [B](SCN) key for 12 second to start upward scan (toward higher frequencies or higher memory channel numbers). ~ ~ "',,, You may also press and hold in either the [UP] or [OWN] key on the ~ _ microphone for % second to initiate upward or downward scanning, re- ~ spectively. 4. Rotate the MAIN DIAL or the SELECT knob counterclockwise to toggle the scanning direction downward. 5. The scanner will now cause the transceiver to increment in the chosen direction until a signal is detected. When a signal is encountered which opens the Squelch, the scanner will pause until the signal disappears (at the end of the other station's transmission), at which point the scanner will resume. While the transceiver is in the "Pause" condition, the decimal points in the frequency display area will blink. See "Scan-Resume Choices" on page 81 for details of how to customize the resumption of scanning. 6. Press the PTT switch on the microphone to cancel scanning. ~ ' .'", The VFO scanning speed is determined via MENU #04 (SCAN SPEED).

Among the memories you have programmed, there may be some stations which you do not wish to scan. For example, weather broadcasts (which are transmitted continuously) will cause the scanner to stop, and such channels may be skipped so as to avoid this inconve- nience. To remove a channel from the scanning loop: I. Recall the memory channel to be skipped. 2. Press the [FUNC] key, as needed, to recall Operating Function Row 4 [SKP, SCN, OW, SCH], then press the [A](SKP) key momentarily. The "SKP" icon will become Bold; this shows that this channel is now not included in the scanning loop. 3. Repeat steps I and 2 as many times as necessary to skip all the channels you do not wish to scan. 4. Initiate memory scanning, you will observe that the channels you marked to be skipped are not included in the scanning loop. 5. Press the PTT switch to stop the scan; you may now use the SELECT knob to step through the channels manually - one at a time - and you will observe that the "skipped" channels are, nonetheless, available for recall by manual means. 6. You may restore a previously-skipped channel to the scanning loop by selecting the channel manually, then pressing the [A](SKP) key momentarily so that the "SKP" icon becomes faint.

To limit scanning (or tuning) within a particular frequency range, you can use the Program- mable Memory Scanning (PMS) feature, which utilizes twenty special-purpose memories ("PGM 001" ~ "PGM 020"). The PMS feature is especially useful in helping you to observe any operating sub-band limits which apply to your Amateur license class. PMS setup is simple to complete. First, store the upper and lower frequency limits ofthe range in a consecutive pair of PMS memories (i.e., "PGM 001" & "PGM 002", "PGM 003" & "PGM 004", etc.). For example, "PGM 003" might contain the lower edge and "PGM 004" the upper. Next recall the first memory of the pair that hold the range you want to scan or tune, then turn the MAIN DIAL knob or pressing the SELECT knob momentarily to activate memory tuning (the "MT" icon will appear on the display). Tuning and scanning are now within the limits of the selected PMS memory pair, keeping opera- tion inside this programmed range. Example: Limit tuning & scanning to the 17-m band I. Press the [VFO/MR] key, as necessary, to recall the VFO mode. Tune to the low edge of the 17-m band (18.068 MHz) and select the desired mode (probably USB or CW). 2. Press the [FUNC] key, as necessary, to recall Operating Function Row 2 [V>M, M>V, RPT, REV]. 3. Press the [A](V>M) key momentarily, then tum the SELECT knob to select memory channel "PGM 001." 4. Press and hold in the [A](V>M) key for Y:z second to write the VFO frequency (18.068 MHz) into "PGM 001." 5. Tune to the high edge of the 17-m band (18.168 MHz), leaving the mode unchanged. 6. Press the [A](V>M) key momentarily, then tum the SELECT knob to select the memory channel "PGM 002." 7. Press and hold in the [A](V>M) key for Y:z second to write the VFO frequency (18.168 MHz) into "PGM 002." 8. Recall memory channel "PGM 001 ", and tum the MAIN DIAL knob clockwise or pressing the SELECT knob momentarily to activate memory tuning. 9. Tuning and scanning are now limited to the 18.068 ~ 18.168-MHz range until you press the [VFO/MR] key to return to memory or VFO operation. 80 FT-/oO MICRO MOBILE OPERATING MANUAL

ceiver then "assumes" that the opening of the squelch corresponds to the discovery of a signal you may wish to listen to. Once the scan has been halted, one of three things may happen: o The default action is that the transceiver pauses on the signal and stays locked on its frequency for five seconds. Thereafter, scanning will resume whether or not the other station's transmission has ended. The pause time is adjustable from 0 to 10 seconds via MENU #05 (RESUME) o Another option is that the scanner will halt until the other station's transmission ceases (at which point the squelch will close). One second after the squelch closes, scanning resumes automatically. o Another option is that the scanner will find a signal, and lock on that frequency without resuming the scan. The above scan-resume choices may be selected via MENU #03 (SCAN MODE). See page 84. DUAL WATCH OPERATION DUAL WATCH is similar, in some respects, to scanning. In DUAL WATCH, however, the trans- ceiver monitors (squelched) on the VFO-A frequency while periodically checking VFO-B for activity. A typical example might be for you to set VFO-A to 50.110 MHz, watching for OX stations who might call CQ on that frequency, while periodically checking 28.885 MHz for stations reporting band openings on 6 meters. To activate DUAL WATCH: 1. Set up transmit and receive operation on VFO-A, establishing your primary monitoring frequency. Set up the frequency to be checked periodically on VFO-B. 2. Recall VFO-A, then rotate the SQl control until the background noise is just silenced. 3. Press the [FUNC) key, as needed, to recall Operating Function Row 4 [SKP, SCN, OW, SCH), then press the [C)(OW) key momentarily to activate DUAL WATCH opera- tion (the "OW" icon will become Bold). 4. The FT -1000 will continue to monitor (squelched) on the current (VFO-A) frequency, but every few seconds will switch briefly to VFO-B frequency, looking for activity. The polling interval can be changed via MENU #06 (D W-TIME). 5. Ifa station is detected on the VFO-B frequency, the FT-lOOO will pause on the VFO- B frequency, and stay there according to the settings of MENU #03 (SCAN MODE) and Menu #05 (RESUME). 6. Press the [C)(OW) key again to cancel DUAL WATCH operation (the "OW" icon will return to its original (non-bold) state). Note that pressing the PTT switch on the micro- phone does not cancel DUAL WATCH operation. FT-100D MICRO MOBILE OPERATING MANUAL 81

The FT-IOO's ~AT System allows the transceiver to be controlled by a personal com- puter. This allows multiple control operations to be fully automated as a single mouse click, or it allows a third-party software package (such as contest logging software) to communicate with the FT-IOO without (redundant) operator intervention. The Optional ~AT Interface Cable CT -62 is a connection cable for the FT -100 and your computer. The CT-62 has a built-in level converter, allowing direct connection from the rear panel ACC Cable Pigtail to the serial port of your computer, without the need for an external RS-232C level converter box. Yaesu Musen does not produce ~AT System operating software, due to the wide variety of personal computers, operating systems, and applications in use today. However, the FT- 100 (and other Yaesu products) are widely supported by third-party software packages, and we recommend that you contact your dealer for advice, or check advertisements in amateur radio journals. Most software vendors also have Home Pages on the World Wide Web which contain a wealth of information on the features and radio support for their software packages. The information presented in this section will allow the programmer to understand the command structure and opcodes used in the FT-! OO's ~AT System. 96 RS-232C IL..no'-----' +- il.:J:::c,' ===lct@-+ CT-62 (Option) Computer D FT-JOO MICRO MOBILE OPERATING MANUAL

£AT DATA PROTOCOL All commands sent from the computer to the transceiver consist of five-byte blocks, with up to 200 ms between each byte. The last byte in each block is the instruction opcode, while the first four bytes of each block are arguments (either parameters for that instruc- tion, or dummy values required to pad the block out to five bytes). Each byte consists of 1 start bit, 8 data bits, no parity bit, and two stop bits. ¢:l CAT DATA BYTE FORMAT ¢:l CAT 5-BYTE COMMAND STRUCTURE There are 13 instruction opcodes for the FT-lOO, listed in the chart on next page. Many of these opcodes are OnJOfftoggle commands for the same action (e.g. "PTT On" and "PTT Off'). Most of these commands require some parameter or parameters to be set. Irrespective of the number of parameters present, every Command Block sent must consist of five bytes. Accordingly, any ~'&T control program must construct the five-byte block by selecting the appropriate instruction opcode, organizing the parameters as needed, and providing unused "dummy" argument bvtes to pad the block to its required five-byte length (the dummy bytes can contain any value). The resulting five bytes are then sent, opcode last, from the computer to the FT-lOO CPU via the computer's serial port and the transceiver's ACC Cable Pigtail. All ~'&T data values are hexadecimal. Note that, unlike most other Yaesu transceivers, the FT-847 serial data cable is a "null modem" ("crossed") type, not a "straight" serial data cable. CONSTRUCTING AND SENDING CAT COMMANDS Example #1: Set the VFO frequency to 439.70 MHz D Per the ~'&T command table, the opcode for "Set Frequency" is OA (set by the "PI" command byte). Placing the opcode into the 5th data bit position, we then enter the frequency into the first four data bit positions: DATA 1 DATA 2 DATA 3 DATA 4 DATA 5 ¢:J '-' _0_0 __ 0_0 __ 9_7 __ 43---, ~ Parameter Opcode Send these five bytes to the transceiver, in the order shown above. Example #2: Turn the Split Mode "ON" D Per the ~'&T command table, the opcode for "Split On/off' is 01 (hex). Placing the opcode into the 5th data bit position, we then enter dummy values into all other param- eter locations: DATA 1 DATA 2 DATA 3 DATA 4 DATA 5 ¢:J ,00 00 00 ,~~ Dummy Data Parameter Opcode FT-IOO MICRO MOBILE OPERATING MANUAL 97
