The FT-2000 is the 2nd Generation in the proud lineage of the FTdx9000 Series! Featuring extensive DSP filtering,

100 Watts of power output, and a host of outstanding ergonomic and performance features.

Above photo is my Yaesu FT-2000 located at my operating position just below the Ten Tec Paragon Transceiver.

The FT-2000 provides a full 100 Watts of power output (AM: 25 W) on the 160-6 Meter Amateur bands.

Continuous receiver coverage from 30 kHz to 60 MHz is provided.

The power of IF Digital Signal Processing (DSP) is yours to enjoy with the FT-2000.

Variable IF Width and IF Shift allow precise interference rejection, and the receiver DSP also includes an

Auto-Notch, Manual Notch, Digital Noise Reduction, and a continuously-variable passband Contour control.

The WIDTH control has a mode-determined adjustment range of 200 Hz – 4 kHz for SSB, and 25 Hz to

2.4 kHz on CW, and a mode-optimized “Narrow” key provides one-touch narrowing of the bandwidth

to a user-determined preset value.

With the FT-2000, you have tremendous control over the fidelity and/or “talk power” of your SSB signal,

thanks to the variable SSB bandwidth capability in the Menu. The default bandwidth is 2.4 kHz

(300 – 2400 Hz @ -6 dB), but you also have selections of 50 – 3000 Hz, 100 – 2900 Hz, 200 – 2800 Hz,

and 400 – 2600 Hz.

The power of DSP also provides tremendous benefits for transmission, as well as reception.

The Three-Band Parametric Microphone Equalizer allows unmatched capability to tailor speech

characteristics: in each of the three bands, you may adjust the center frequency of the equalization,

the frequency spread over which the equalization is applied, and the amplitude (peaking or nulling)

within that equalization range. The result is sparkling, clear audio that will be the envy of everyone

else on the band!

Following in the renowned path of the FTDX9000, the FT-2000 is crafted with a comprehensive

design view that accounts for all aspects of the strong signal environment, and especially with optimization

of weak-signal in a multiple-strong-signal environment. The receiver of the FT-2000 is a triple-conversion

type, utilizing great care in the gain distribution through all IF stages. The first mixer is a GaAs FET Doubly

-Balanced Mixer type, fed by a four-VCO PLL synthesizer

(30 kHz – 10.5 MHz, 10.5 MHz – 24 MHz, 24 MHz – 39 MHz, and 39 MHz – 56 MHz). The resulting

first IF is at 69.450 MHz, utilizing an up-conversion technique that yields excellent image rejection.

Close up of the S Meter.

The first IF of the FT-2000 features three roofing filters, I bandwidths of 15 kHz, 6 kHz, and 3 kHz,optimized by mode for best performance on today’s crowded bands. Especially useful during busy contest weekends, the Roofing Filters are positioned right after the first mixer, improving IP3 (3rd-Order Intercept Point) performance for all stages that follow.When operating at a frantic pace, it’s a comfort to have such comprehensive information available onthe front panel’s huge display. The FT-2000’s unique "Receiver Configuration Display” calls out status for each step in the receiver’s RF and IF, and the fluorescent display also provides both graphical and numerical depiction of the bandwidth and the alignment of the various interference-rejection filters. And the high-resolution analog multi-meter allows you to monitor PO/COMP/SWR/ID/VDD/ALC both effortlessly and precisely.During Split operation, Dual Receive may be engaged so that you may listen to both sides of the pile-up (or watch a particular frequency on the same band for activity). One push of the appropriate [TX] or [RX] indicator will engage or disengage the receiver or transmitter on the Main or Sub VFO, and the [TXW] (TX Watch) button also lets you listen to your transmit frequency during casual Split operation.The Sub Receiver also has a slot for an optional Collins® Mechanical CW filter, if desired: choose the YF-122C (500 Hz) or the YF-122CN (300 Hz). The Sub Receiver is an analog type, with no DSP filters.Close up of the FT-2000 operatiing on 17 MetersThe 99 memories may be organized into up to five memory groups (up to 20 channels each), and withthe addition of the optional DMU-2000 Data Management Unit, you can connect your keyboard (not supplied) and add memory labels (names), edit data, and perform backup and other functions, as well, using an external computer monitor (not supplied). In addition, the one-touch Store (STO) and Recall (RCL) keysallow you instant access to a five-channel Quick Memory Bank that gives you access to five frequencieson a first-in, first-out running basis. For storage and playback of repetitive messages you have to transmit in a contest, the four-channel Digital Voice Recorder (5 channels when using the optional FH-2 Keypad) will quickly and efficiently let you store CQ, Contest Number, and “QRZ” messages. On receive, a running15-second loop recorder lets you stop the recording and play back the just-received audio, so you can confirm a callsign, for example.The front panel’s oversized 2.67” (68 mm) Main Tuning Knob is crafted using a brass JISC3604R alloy, for easy flywheel-effect frequency excursions or precision tuning of weak digital signals. The torque of thetuning knob shaft may be adjusted for just the amount of drag you prefer, and all it will take is one spin ofthe dial for you to know that you are in command of a serious radio!The 100 memories of matching-point data allow you to tune around the bands without the need to re-tune as you go. The special antenna tuner memories ensure efficient operation, as well as lightning-fast matching at new operating frequencies, as needed. The Automatic Antenna Tuner has a matching range of 16.7 to 150 Ohms (50 MHz: 25 - 100 Ohms).Flexible Connection Points for RTTY, SSTV, PSK31, JT65 (EME) and other Digital Modes; VOX (Automatic voice-operated TX/RX control); All mode Squelch; FM Mode: 50-Tone CTCSS Encode/Decode System; Band-Specific Repeater Shifts for 29/50 MHz FM; Wide/Narrow modes for AM and FM; Flexible, easy-to-use VFO/Memory command selections: A>B, A=B, V/M, M>A, A>M; Memory Channel Offset Tuning (MT); Versatile Scanning Capability; Versatile Menu Mode for customization of setup and features; Transverter Jack; Constant-level rear-panel sound recording jack; Comprehensive external RS-232C computer control (CAT) protocol; Optional FH-2 Keypad provides ease of control for CW or Voice Messages and Receiver Loop recording.Future Options that are available:The Ultimate Low-Band DXer RF Preselection Filter: YAESU’s Exclusive µ-Tuning!

On the lower Amateur bands, the signal voltages impinging on a receiver can create noise and Intermodulation effects that can cover up weak signals you’re trying to pull through. So YAESU’s engineers developed the µ (Mu) Tuning system for the FTDX9000, and it’s now available as an option for the FT-2000. Three modules are available (MTU-160, MTU-80/40, MTU-30/20), and these modules may be connected externally with no internal modification required! When µ-Tuning is engaged, the standard VRF (Variable RF Preselector) system is bypassed, but the fixed Bandpass Filters are still in the received signal path. The µ-Tuning filters utilize a stackof large 1.1” (28 mm) Ni-Zn Ferrite cores, driven through a silver-plated coil assembly by a precision stepper motor. The resulting high Q (typically over 300) provides a very steep resonance peak near your operating frequency. The peak may be adjusted away from your frequency, for even greater protection from a specific station, and a graphical depiction of the µ-Tune filter alignment appears onthe front panel of the transceiver.

Enhance Operation using External Display (option)!

A wide array of informative and useful displays, identical to those available on the FTDX9000D, can be obtained by adding the optional DMU-2000 Data Management Unit and an after-market display (not supplied). You get an Audio Scope (plus “Waterfall”) and Oscilloscope, Logging Page, Band Scope, World Clock with Sunrise/Sunset Terminator Display, Swept-frequency SWR display, Memory Channel listing, Rotator Control display with Great Circle Map, and a comprehensive Menu listing, as well.

You may be asking why the hell would I still want and still keep (and use!) a 30-year old, bulky, heavy ‘boat

anchor’ transceiver? For collecting, good performance? At the time of it's release it was the top of the line for

Yaesu and was competition grade. Performance wise, many years down the line it is still ranked no. 15 currently

as far as close in dynamic range for high performance transceivers is concerned and is still quite hard to beat.

In fact many of the so called top of the range HF transceivers now do not have a RF front end that is so hot to

trot and cannot even touch the Yaesu FT-901DM. That is the real reason - performance. Yes this amazing old

vintage radio has a receiver can perform or out perform better the the expensive models of today! Matched with

the FTV-901R transverter and I have a high performance VHF/UHF operating system.

The real “breakthrough” feature of the Yaesu FT-901DM was the memory system. In a day when the only

concept of “memory” was a quartz crystal, the FT -901DM allowed the operator to push a button, wait about

five seconds, and in that time the synthesizer would lock in on the current operating frequency and store it for

later recall. No other HF radio in the Ham world had memory, and it was a huge performance breakthrough

that set the stage for the memory-based transceivers of today.

Another area where the Yaesu FT-901DM shone was in its much improved receiver performance.

The FT-901DM was the result of a major effort by Yaesu’s top receiver design engineers, who included a

permeability-tuned RF preselector (similar in concept to the “µ-Tuning” modules in today’s FTdx9000!

Now may be you will sit up and take note), and the entire receiver section featured at least 10 dB more

dynamic range than any previous solid-state receiver from Yaesu. At the time, the dynamic range of the

FT-901DM was, by far, the best in the industry, and it led to the wide acceptance of this model in DX and

contest circles. Indeed the close in dynamic range is topped today by only a few other very special class top of

the range HF transceivers but at much higher prices! So if you can find a FT-901DM or a Ft-902 in good overall

condition, it is worth buying one as a second rig. The differnce between the 901 and 902 is purely one of bands,

the 902 has the WARC bands included, everything elese is the same.

Don't take my word for it, take a close look at the receiver tests, done by Bob Sherwood of Sherwood

Engineering (link). Even after 30 years, the FT-901 is still ranking #15 - defeating numerous modern transceivers

with ease. Bob is a respected RF Engineer and what he says about receiver design performance and rankings is

basically accepted as Gospel by DXers the world over and is not disputed.

On the transmitter side, the 901 uses a pair of 6146B tubes in the finals, and utilized RF negative feedback to

ensure low IMD products. The 901 series was always renowned for its outstanding audio quality and signal purity.

Now do you want receiver performance or bells and whistles?

Finally, the FT-901DM included a built-in Curtis Model 8043 Electronic Keyer. The Curtis IC was the “prestige”

keyer of the day, and it eliminated yet another box from the desk of an owner.

Powered by 2 x 6146B Tubes:                            

My Interface between computer and transceiver for digital communications is done by a USB LinkAll from FeatureTech of New Zealand. See below: Designed and built by BA3DP and made in China.

The interface allows the operation of digital transmission modes such as RTTY, CW, SSTV etc.

I have owned the Ten Tec Paragon Transceiver for some time now and I can say that this transceiver

 is a steady and stout performer even by today's standards and the front end and transmitted audio

can hold it's own agaist some of the big boys. The general specifications in brief are :

Paragon, Digital Readout, 100 watt, 160-10m, SSB, CW, Optional FM, 5 filter positions,

62 memories, Speech Processor, Noise Blanker, Dual VFOs, Clock, Optional RS-232 and

Voice Board.

Mine is fitted with the additional 1.8 SSB Crystal Filter, the RS-232 board and the FM Board.

I purchased this secondhand from Ten Tec direct and I can say that their service is second to none

YAESU - FT-857D 

The FT-857D, the world's smallest HF/VHF/UHF mobile transceiver, provides

base station-type performance from an ultra-compact package that's ideal for

mobile or external battery portable work. Wide frequency coverage, outstanding

receiver performance, and the convenience of optional remote-head operation

make the FT-857D the expert's choice for high-performance mobile operation!

The new FT-857D version includes coverage of the U.S. 60-meter (5 MHz) band,

plus the previously-optional DSP circuitry

Measuring just 6.1” x 2” x 9.2” (155 x 52 x 233 mm), the FT-857 is the world’s smallest full-power

HF/VHF/UHF multimode transceiver! Its rugged case design is a masterpiece of ergonomic design,

with often-used switches and knobs conveniently positioned for easy access.

Photo above: The FT-857D sits on top of the SP-100 external speaker. The audio is of much higher quality feed

into an external speaker. A radio that glows in the dark and it's not a boat anchor rig of yester year!

Building on the acclaimed performance of the FT-1000D, Mark-V FT-1000MP, and FT-897, Yaesu’s engineers

have crafted the FT-857’s front end for a very low noise floor, along with wide dynamic range. Utilizing an

up-conversion architecture for HF with a first IF of 68.33 MHz, the FT-857 features a double-conversion

superheterodyne system (triple conversion on FM), with the 2nd IF at 10.7 MHz. Extensive bandpass filtering in

the front end, along with careful device selection and gain distribution, yield a receiver system ready for the

strong-signal challenges of today’s crowded bands!

Providing transmitter coverage of the HF, 50 MHz, 144 MHz, and 430 MHz Amateur bands, the FT-857 also

includes receive coverage on 100 kHz to 56 MHz, 76 to 108 MHz, 118-164 MHz, and 420-470 MHz.

Enjoy the excitement of public safety monitoring, along with weather broadcasts, AM and FM broadcasts,

aviation communications, as well as the action on the Ham bands!

Photo above: Another close up of the Yaesu FT-857D.

The FT-857 provides up to 200 “Main” memory channels, each of which may be named with an Alpha-Numeric

label of up to eight characters. These 200 Memories may be separated into as many as 10 Memory Groups of 20

Memories each. For added convenience, you also get a “Quick Memory” and a “Home Channel” on each band,

plus ten pairs of band-limit memories, to let you restrict operation to a sub-band, if you like.

For superior interference rejection and transmitter “talk power,” the FT-857’s DSP circuitry enhances both sides

of the communications circuit. The FT-857’s DSP Unit features a 24-bit high-tech D/A chip for signal processing.

Included are Bandpass Filter, Auto-Notch, and Noise Reduction filters, along with a Microphone Equalizer.

Photo above: The yaesu RF engineers thought of everything! They provided an external "S: Meter jack so that

users could have the option of adding an external "S/RF" Meter of an analog type. The photo shows my "HUGE"

Workman MD-4 external S/RF Meter plug in to the FT-857D, the bottom left shows the gold plug from the

"S" meter plugged into the FT-857D.

Ease of operation of the FT-857 is enhanced by the large-diameter (1.7”) Main Tuning Dial, similar in size to the

tuning knob of many base station rigs. Selectable tuning steps of 2 kHz/4 kHz per revolution allow easy navigation

around your favorite bands, while important keys and switches are strategically placed around the front panel for

quick access.

The Ultra Compact All-in-one Transceiver:

The Yaesu FT-857D is a ultra compact all-in-one compact transceiver covering HF-430 MHz.

Inside the enclosure is an MF, HF, VHF and UHF transceiver with most of the bells and whistles that any

operator could want, and supplied is a 100 watt TX on 160-6 meters, 50 watts on 2 meters, and 20 watts

on the 430 MHz band. It is capable of operating in the CW, AM, SSB, FM, Packet and digital modes.

The engineers have built a transceiver, which could be installed in a vehicle, with a removable face plate

which can be mounted separately from the electronics package. 

The purchase of FT-857D was for a back up radio to basically cover all the major operational bands that

are used at my station.

The transceiver frame is made of an aluminum casting, which makes a very solid mechanically. The FT-857D is

built to survive the harsh environment of mobile operations and long term use.

Photo above: Shows the high quality Collins Mechanical Filters  for SSB and CW.

Receive audio is good – The primary limitation on receive audio for this type of transceiver or similar

models such as the Yaesu FT-100, Kenwood TS-50, Icom IC-706 Mk II G and Icom IC-7000 etc

is the small speaker used and size of the cabinet . I plugged it into a Trio SP-100 as you can see from

my photos, and the audio is as good as or better than any other ham radio I have used.

There is a headphone jack on the front left side of the FT-857D, which makes using headphones easy.
 

External "S/RF" Meter Provision" – The Yaesu RF design engineers did give allot of thought into

the design of this radio, they realized the limitation of the size of the LCD S meter on the radio and provided

an external "S/RF" Meter connection socket so you can connect your own analogue style meter. Well I

did just that and you can see that I connected up my monster size "Workman MD-4" S Meter. LDG makes

also a similar monster sized S Meter for this radio called the "FT Meter" and that is also an attractive meter.
