Yaesu FT-DX3000

  • TX Frequency Coverage: 160 - 6 meters
  • RX Frequency Coverage: 30 kHz - 56 MHz
  • Operating Modes: USB, LSB, CW, AM, FM
  • Digital Noise Reduction
  • Large 4.3 inch (dia.) colour TFT display
  • Power Output: 5 to 100 watts HF - 6m
  • IF DSP
  • Built-in Electronic Keyer
  • Built In Antenna Tuner
  • High Speed Spectrum Scope

The Yaesu FTDX3000 transceiver provides ultimate weak signal receiver performance in crowded, strong signal environments. General coverage receive is available from 30 kHz to 56 MHz. Power is adjustable 5 to 100 watts for the amateur bands from 160 to 6 meters. A built-in 4.3-in TFT wide full colour high resolution display provides superior operability and visibility for the FTDX3000D user. A High Speed Spectrum scope located just below the LCD display gives the operator all the information needed to place them at the right place on the band with the right receiver set-up to have a satisfying experience with a casual QSO chat or while digging out a rare desired weak signal contact. Other refinements include: USB interface, 9 MHz IF output, RX-only antenna input, RTTY/PSK encoder/decoder, High speed antenna tuner and a specialized 50 MHz amplifier. 



FT DX 3000 Brief Description

Rugged 100 Watt Output Power


The Amazing Crystal Roofing Filter performance has been proven in the FT DX 5000

The Down conversion 9 MHz 1st IF frequency receiver construction can realise narrow 300 Hz (optional), 600 Hz and 3 kHz bandwidth roofing filters.

Implementing the extra sharp Crystal Roofing Filters provides superior close-in dynamic range and affords the best receiver performance possible.

Outstanding Receiver performance is the heritage of the FT DX 5000
The Essential elements in receiver performance are the RF amplifier and the 1st mixer.

The RF Amplifier has optimized NF points, and the over-sized wide range RF transformer exhibits minimum saturation in strong signal processing. The optimized devices were selected to guarantee superior multi-signal RX performance.

The desired maximum performance has been realized in the development of the FT DX 3000 receiver circuitry. This new radio has the high dynamic rance IP3 performance that was realized and proven in the FT DX 5000.

IF DSP provides effective and optimized QRM rejection
The 32 bit high speed floating decimal DSP (max 2800 MIPS) provides effective cancellation/reduction (DNR) of the random noise that is frequently found on the HF Frequencies.

Auto-Notch (DNF) that automatically eliminates the dominant beat tone

CONTOUR and APF; very effective receiver noise reduction tools in the HF band operations.

Yaesu original DSP QRM and noise reduction are also provided with the new FT DX 3000.

Large and Wide Colour LCD Display
The high-resolution (480 x 272 dots) 3.5-inch wide colour LCD displays the operating information and the status of the transceiver functions.

The various FT DX 3000 functions are displayed on this LCD and provide the operator with easy to read operating information.

High Speed Spectrum Scope built-in
Although the FT DX 3000 only has one receiver, a high speed Spectrum Scope is built into the radio.

When in Auto Mode, the Spectrum Scope display is updated in real time.

The maximum bandwidth of the scope is 1 MHz, and the minimum span width setting is 20 kHz. The best desired span is selectable for the high-resolution display. The current band activity can be monitored in real time.

AF SCOPE display and RTTY/PSK encoder/decoder (optional)
The optional AF SCOPE and optional RTTY encoder/decoder functions have been developed for the FT DX 3000.

The wave form of the AF SCOPE signal can be displayed on the TFT LCD. Also, the RTTY/PSK text may be displayed on the LCD.


Independent Frequency Display
The Main operating frequency is the most important display in the radio, with VFO-A frequency located just above the main dial.

The newly-developed LCD has a wider viewing angle and higher contrast for convenient and effortless viewing.

Other Features

  • Built-In Specialised Receiver amplifier for 50 MHZ
  • Three antenna connectors are provided, with the possibility of assigning the "ANT-3" connector to "RX-Only"
  • Signal output for an external receiver
  • 9 MHz IF output
  • High Speed Automatic antenna tuner built-in
  • Optional µ-tune unit available
  • USB Interface

The FTDX3000 requires 13.8 VDC at 23 amps. This radio comes with the MH-31B8 hand mic, DC cable spare fuses and plugs. 14.4 x 4.5 x 12.4 inches 22 lbs. (10 kg).
