FT-1000D
"The Best of the Best"
200W HF ALL MODE TRANSCEIVER

Designed with no spared effort or expense for optimum performance and operability, the FT-1000D is the fruit of over 25,000 man-hours of intensive research and development by Yaesu’s top design engineers. Instead of merely offering incremental improvements on existing designs or adding bells and whistles to an old model, the FT-1000D project involves a wholly new approach to the application of the latest digital and RF technologies to today’s most demanding needs on the HF bands. Extensive surface-mount component technology allowed six microprocessors and five Direct Digital Synthesizers to be harmoniously integrated with a simple operator interface into a highly reliable full-featured transceiver optimized for serious HF applications.

Five Direct Digital Synthesizers
Developed independently by a specially appointed in-house engineering research team, two 10-bit Digital Synthesizers in the FT-1000D provide exceptionally clean vfo sources to drive the PLL local oscillators, resulting in very low carrier noise on transmitted signals, and wide receiver blocking dynamic range. The fast, stable PLL locking time and three additional 8-bit DDSs controlling the IF functions result in unsurpassed IF control, a tuning feel as smooth as an analog vfo, and quick transmit/receive turnaround (typically 18 ms) for QSK CW and high-performance digital ARQ modes. To take full advantage of this level of synthesis the FT-1000D is supplied as standard with a 2-ppm (0 to 50 °C) master oscillator, with a 0.5-ppm (-10 to +60 °C) TCXO optional.

Flexible Receiver Front-end With Broad Dynamic Range
Excellent receiver strong signal handling results from fourteen 5-pole main channel front end bandpass filters (plus eleven optional sub channel bandpass filters) followed by a switchable cascode dual JFET RF amplifier and double-balanced mixer ring using four high-IDSS JFETs. According to band conditions, you can choose between the preamp, direct mixer feed, or direct feed with attenuation selectable in three 6-dB steps (to coincide with S-units). Typical measured two-tone dynamic range is 108 dB (+32 dBm 3rd order IP) with the RF amplifier off, and a noise floor of —138 dB with it on (50 kHz spacing at 14.260 MHz, 500 Hz BW, CW mode with no attenuation).

Simultaneous Dual (Unlimited) Frequency Reception
Dual receiver front ends, IF strips and vfos allow simultaneous reception and display of two different frequencies, even in different modes and with different IF bandwidths. A single RX MIX control allows adjusting the relative volume of each channel without having to twiddle multiple knobs. Unique to the FT-1000D, each vfo has its own flywheel-weighted tuning knob, requiring no confusing pushbutton selections to tune either frequency. The audio of each vfo can be monitored mixed or split between each ear (with headphones or external stereo amp). Also unlike any other radio, the eleven additional filters in the BPF-1 Sub-Vfo Bandpass Filter option allow the two frequencies to be up to 29.9 MHz apart (using a second antenna). For example, you can monitor WWV on 10 MHz while simultaneously working SSB or CW on 28 MHz, and freely tune either or both frequencies without pushing a single button. (Without the BPF-1 option the main and sub vfos must share the same antenna and bandpass filter). Note that with or without the BPF-1, a separate receiving antenna can be connected and selected from the front panel —important for serious 160m operations. The FT-1000D’s dual receive design allows frequency, mode and filter diversity reception, plus antenna diversity reception with the BPF-1 option.

QRM Rejection Systems
A tunable (±1.2 kHz) notch filter in the 100 kHz 4th IF provides more than 40 dB rejection of unwanted heterodynes or CW signals in all modes (except FM). A sharp 4-pole tunable audio peak filter allows comfortable separation of CW signals in crowded bands. IF shift provides fine adjustment of the filter center frequency up to ±1.12 kHz on the IF bandpass, and single-control IF width allows narrowing the actual IF passband without affecting the center frequency. Separate wide and narrow pulse noise blanker circuits can be selected independently for both "woodpecker" and switching transient noise suppression.

Optimized Digital Communications Modes
Special provisions for RTTY/AMTOR and packet modes include an independent built-in microprocessor to control AFSK generation for RTTY/AMTOR, providing selectable 2125- or 1275- Hz Mark tones and 170-, 425-, and 850-Hz shifts, with upper or lower shift selectable with RTTY mode button. The display can show the Mark frequency, or be loaded with any desired offset. The 500-Hz BW crystal filters can be selected for RTTY, AMTOR and 300 baud packet, and IF offset can be selected from four standard settings matching most popular TNCs, so that received signals are centered in the IF and the display shows the actual center frequency of the two transmitted tones. Of course, any non-standard tone pair/shift can also be accommodated with manual IF shift and independent display offset adjustment (from the front panel). The PACKET mode button selects LSB, or FM (with 1000-Hz shift). A separate RTTY terminal unit and TNC can both be connected independently at the rear panel. FAX and SSTV can also be used in SSB modes.

Flexible Mode and IF Filter Selection
Each receiver IF (Main and Sub) has its own vfo on each of the ten bands, and each of these vfos has two sub-band channels per band. Each of these 40 tunable vfo channels plus the 99 knob selectable tunable memories have independently selectable modes and receiving IF filters. For the main receiver, four crystal filters are provided as standard in the 8.2 MHz 2nd IF, and two in the 455-kHz 3rd IF, providing bandwidths of 250 and 500 Hz, and 2.0, 2.4 and 6 kHz with four optional filters available for the main 455-kHz IF. In addition, the sub receiver comes with a 2.4 kHz BW filter in the 7.68 MHz 2nd IF and another 2.4-kHz filter in the 455-kHz 3rd IF, with a 3rd IF 600-Hz narrow filter available as an option. Selecting filters does not affect the receiving frequency, so for example, you can switch bandwidths from 2.4 kHz to 500 Hz during a CW QSO without retuning.

Up to 200 Watts Transmitter Output
While other transceivers offer maximum output of 100 or 150 watts, the FT-1000D gives you clean, continuously adjustable output from 20 to a full 200 watts (50 watts AM carrier), for that extra edge needed in pileups, or to easily drive big linears to the legal limit. The clean DDS-derived local signals combined with 30-volt Vcc to the (MRF422) final transistors results in a typical transmitter 3rd-order IMD of —36 dB (at 150W PEP). An extended transmit duty cycle of 30 minutes cool, quiet keydown power (@ 100W) results from employing a 10-inch wide squirrel cage blower (instead of the usual fan) and internal interlaced heat sinks. A separate RF PWR (ALC threshold) control allows full adjustment of power output in all modes, and a transmitter RF (not IF) monitor lets you hear just what you’re sending to the antenna. The built-in quick response antenna tuner matches SWRs up to 3:1 on the amateur bands, and includes 39 tuner-setting memories for instant recall of previously stored settings. The antenna tuner controls are also accessible by external computer via the CAT System.

Special Features for CW Operation
Along with the wide array of IF filters and the tunable audio peak filter, the FT-1000D provides selectable bfo offsets of 400-, 500-, 600-, and 700-Hz pitch, with matching CW spotting oscillator (to zero-beat your transmitter while receiving) and transmit sidetone. A novel PLL-controlled visual spotting indicator is also provided to facilitate spotting. In addition to front panel speed control, the built-in electronic squeeze keyer includes 15-step weight selection from 1:3 to 1:4.5 dot/dash ratios. Key jacks are provided on both front and rear panels. The CW carrier is injected at the USB side of the IF center frequency, so you can switch between CW and USB without retuning.

Enhanced Integration = Simplified Control
To ensure simple operator control, an 8-bit HD64180 master CPU works in concert with five supporting microprocessors to manage the frequency synthesis and complex functions of the FT-1000D. "Shifted" key functions have been eliminated, except for numeric frequency entry on the keypad, which otherwise provides one-touch instant band selection. Separate buttons are provided for all other significant functions including vfo, mode, and IF and audio filter selection. A detented rotary selector is used for the 99 memories, which can be independently tuned or have their mode or IF filter selection changed directly, just like a vfo. The Clarifier (receive/transmit offset) can be adjusted and is displayed and stored independently of the operating frequency, being added to the main display when either the transmit or receive clarifier is activated. Clearing either clarifier retains the offset on its separate display for instant reuse. The CAT (Computer-Aided Transceiver) System in the FT-1000D allows control of major functions from an external personal computer. The FT-1000D is supported by most DX and contest logging programs.

DVS-2 Digital Voice Recording Option
Designed especially for serious DXing and contesting, the DVS-2 option can be used to store receiver audio continuously. Pressing the STOP button saves the last 16 seconds of audio in digital memory, which can then be played back through the transceiver’s loudspeaker or earphones (repeatedly, if desired). In its transmitting mode, for contest or DX calls, the DVS-2 can record either two 8-second messages or four 4-second messages via the microphone, and then play back selected messages on the air at the touch of a button.
