The HF world is Yaesu's world, and now you can own the smallest full-featured HF/VHF/UHF transceiver in the world: The FT-100 Micro Mobile Series. With frequency coverage from HF to UHF, built-in DSP, and 100 Watts of HF/50 MHz power output, the FT-100 keeps you in touch with the world, at home or away.


The FT-100 is the smallest transceiver in the world providing such wide frequency coverage. Providing transceiver coverage of the HF, 50 MHz, 144 MHz, and 430 MHz amateur bands on SSB, CW, AM, FM, AFSK Teletype, and Packet, the FT-100 also includes receive coverage of
I00KHz through 970 MHz, so you can monitor public safety, weather broadcast, AM and FM broadcast, and TV audio transmissions, in addition to all the action on the ham bands. All this from a rugged compact case measuring just 160 (W) x 54 (H) x 205 (D) mm (6.3" x 2.2" x 8.0")!

Building on the acclaimed performance of the FT-1000D, FT-1000MP, and FT-847, Yaesu's engineers have crafted the FT-100's front end for a very low noise floor and wide dynamic range. Utilising an up-conversion architecture for HF with a 68.985 MHz first IF, the FT-100 features a double-conversion superheterodyne system (triple-conversion on FM) with the 2nd IF at 11.705 MHz. The first mixer is a low-noise, high-intercept design using SST310 JFETs in a doubly-balanced configuration. On 144/430 MHz, the very- low-noise GaAs MES FET SGM2016 preamplifier is followed by an HSB88 diode-ring mixer, yielding the excellent Noise Figure required for weak-signal work. The front-end devices are individually selected and matched, ensuring a high level of performance consistency as units are manufactured.
To ensure the dual goals of low receiver noise floor and wide dynamic range, Yaesu's engineers utilise an AD9850 Direct Digital Synthesiser (DDS) for the main local oscillator of the FT-100. Providing fast locktime and excellent Carrier-to-Noise (C/N) ratio, the DDS also yields tuning steps as small as 1.25 Hz, for silky-smooth action indistinguishable from an analogue VFO system. The PLL circuits in the FT-100 feature a low-noise custom J-FET device (FQ7925), thus enhancing system performance.
* IF Shift : Use the IF SHIFT feature to vary the center frequency of the IF passband, so as to eliminate interference above or below the current operating frequency.

* IF Noise Blanker : Optimised for use in the mobile environment, the FT-100 includes an effective IF Noise Blanker specially designed for suppression of ignition and other pulse-type noises. The Noise Blanker's threshold is adjustable via the MENU system.

* Intercept Point Optimisation (IPO): For reception on the lower frequencies, where very low Noise Figure is not required, the IPO feature causes the RF preamplifier to be bypassed, allowing direct signal input to the first mixer. An input attenuator is also available, for reception under extremely noisy conditions.

* Adjustable AGC : The Automatic Gain Control (AGC) circuitry of the FT-100's receiver may be adjusted, via the MENU, for SLOW or FAST receiver recovery times. A convenient "AUTO" setting programs "FAST" AGC for CW, and "SLOW" for voice modes.

* Clarifier (RIT) : For split-frequency pile-ups or to follow drifting signals, the Clarifier control provides upto ±9.99 kHz of adjustment of the receiver's frequency, without changing the transmitter frequency. For wider-split pile-ups, the "SPLIT" mode allows you to use VFO-A and VFO-B separately, too.

* RF Gain Control : For noise reduction and/or variation of the AGC system threshold, the MENU allows the front panel's Squelch control to be switched to operate as an "RF Gain" control.

* VOX : For hands-free voice operation, the VOX system includes MENU adjustments for both VOX Gain and Delay. A separate setting is also provided for receiver recovery in the CW mode.

The A, B, C, and D keys below the display provide access to many control functions for the FT-100, including VFO selection, Memory Channel loading, Repeater Shifts and Tones,and Filterselection.
The FT-100 provides 6 Memory Groups of 50 Channels each, for a total of 300 "Regular" memories. In addition, you get 20 "Split Frequency" memories, 5 Quick Memory Bank (QMB) memories, 4 "Home" Channel memories, and 20 Band-Limit memories, for a grand total of 349 Memory Channels! Use the QMB or Home channels for Quick QSY to a favourite frequency, and use the Split memories for DX-pedition pileups or 7MHz SSB work.
The large (70 mm x 30 mm) blue LCD dot-matrix display provides easy-to-read indication of many operating functions, including frequency, RX and TX metering, operating functions, status icons, and the Spectrum Scope bar-graph. And to set the illumination level precisely to the brightness you want, the MENU provides a "Dimmer" feature with 64 degrees of illumination.
For mobile operation where mounting space is very limited, the optional YSK-100 Separation Kit allows the front panel to be remotely mounted on your dashboard, with the transceiver stashed away in available space. Data is transferred between units at a lightning-fast rate of 62,500 bps, for seamless remote operation.
* Two Antenna Jacks (HF/50 MHz, 144/430 MHz) using Type M (UHF) connectors

* Three Programmable Microphone Keys (ACC, P1, and P2) for easy feature access

* Easy Linear Amplifier interface

* Easy-to-use MENU system for custom "Set and Forget" configurations.

The FT-100's power amplifier section utilises MOSFET devices, providing low noise, low distortion, and high reliability. The HF/50 MHz amplifier provides 100 Watts of output, while the VHF/UHF section generates 50 Watts of power on 144 MHz, and 20 Watts on 430 MHz. Reliability is assured thanks to the extensive cooling system, featuring twin cooling fans and an aluminium diecast chassis.
For superior interference rejection and transmitter "talk power," the FT-100's DSP circuitry enhances both sides of the communications circuit. The FT-100 DSP Unit features a 24-bit high-tech D/A chip for signal processing.

* Digital Dual Bandpass Filter : Providing "brick wall" audio selectivity for voice modes, the Bandpass filter allows independent High-Pass and Low-Pass Filter adjustments, with cut-off frequencies of 100 Hz - 1000 Hz (HPF) and 1000 Hz - 6000 Hz (LPF). On CW, the Bandpass filter becomes an Audio Peaking Filter with available bandwidths of 60/120/240 Hz.

* Noise Reduction Filter: BuiIding on the highly-successful Noise Reduction feature of the FT-920, the FT-100's DSP utilises multi-parameter analysis for efficient processing and reduction of incoming noise. A total of 16 Noise Reduction settings are available for best results under changing conditions.

* Automatic Seeking Notch Filter: For removal of annoying carriers or heterodynes, the DSP Notch Filter will identify and suppress one or more such signals automatically, thus improving copy and reducing operator fatigue.

* Microphone Equaliser : To match the FT-100's transmitter audio response to the waveform produced by your voice and the microphone in use, the DSP system includes a three-position Mic Equaliser circuit. The result is increased "talk power" as extraneous frequencies are suppressed, allowing all available power to be concentrated into your voice's pattern.

* Built-in Electronic Keyer: The FT-100's built-in Electronic Keyer includes Dot : Space and Dash : Space weight adjustments.

* CW Message Memory : For repetitive "CQ DX" or "CQ TEST" messages, the FT-100 includes a 50-character CW Message register.

* CW Full Break-in (QSK) : Both "Full QSK" and "Semi-Break-In" CW modes are available, with excellent keyed waveforms in both modes.

* CW "Reverse" Reception : When interference is encountered in the CW mode, the "Reverse" feature allows the injected sideband to be changed between "USB" and "LSB" by a simple press of the "MODE" switch on the front panel.

* CW Pitch/Sidetone Control : The CW PITCH control allows the transmitted signal to be offset 400/500/600/700/800 Hz from "zero beat" with the receive frequency. This adjustment simultaneously varies the center frequency of the RX passband (including the DSP BPF), as well as the CW Sidetone's pitch. The sidetone therefore serves as a "Spot" signal during tuning.

* Optional CW Filters : Available options for the FT-100 include the 500 Hz XF-117C and 300 Hz XF-117CN crystal filters. both of which may be installed at the same time.
The front panel's SELECT knob acts as a Quick-QSY dial for tuning, with independent steps on different bands and modes. The SELECT knob is also used for Memory Channel and MENU item selection, as well as CLARIFIER tuning and IF SHIFT adjustment.
For operation on a wide variety of data modes, including 1200/9600 bps FM packet, RTTY (AFSK), or SSTV, the rear- panel's 6-pin mini-DIN connector provides easy access to Data I/O lines, plus PTT and Ground.
* VFO Scan: Scan up or down the band in the VFO mode.

* Memory Scan : Scan within the current Memory Group, or scan all the memories.

* Programmable Memory Scan (PMS): Use PMS to scan within band limits set by the special PMS memories.

*QMB Scan : When operating on the QMB channels, you can also elect to scan just those memories.  During scanning operation, the FT-100 can be set up to Stop completely when a signal is encountered; to Hold until the incoming transmission ceases: or to Resume after a delay of  1 to 10 seconds.

* Automatic Repeater Shift: On the 144 MHz and 430 MHz bands, the FT-100 will automatically activate the repeater shift appropriate for the part of the band in which you are working.

* CTCSS/DCS Tone Systems : For repeater access, a CTCSS Encoder is built into the FT-100 (FTS-27 Decoder optional), and for advanced systems a 104-code Digital Code Squelch system provides improved immunity from false decoding.

* SmartSearch™: When visiting a new city, use the Smart Search™ system to scan the FM band for activity. When busy channels are found, they will be automatically loaded into a special Smart Search™ Memory Bank, for easy recall.

* Spectrum Scope: If you have to be away from your radio for a few minutes, turn on the Spectrum Scope to keep watch on band activity. The Spectrum Scope will create a bar-graph display of activity an 15 channels above and below your current operating frequency.

* ARTS™(Auto-Range Transponder System): During Search-and-Rescue operations, the ARTS™ feature will notify you if a field station (for example, a hand-held unit) has gone out of communications range, so you can instruct them to move to a better location.
