160 through 6 Meters - SSB/CW/FM/AM/Digital
With efficient dimensions of 14.4" x 4.5" x 12.3" (W x H x D) and weighing in at only 22 pounds, the FT DX 3000D is a solidly packed tranceiver ready to give very high performance on all Amateur Radio bands from 160 to 6 meters. • General Coverage Reception from 30 kHz to 56 MHz • FM & AM - Wide and Narrow modes included
RTTY/PSK31 Encode / Decode Included
Various easy connections available for RTTY, SSTV, PSK31, JT, and other Digital Modes
100 Watts of Solid Performance
The RF Final Amplifier produces a clean 100 watt (some modes less)transmit signal. A large heat sink is combined with the die cast aluminum chassis for efficient heat dissipation. A cooling fan located beside the final amplifier and the TX Low Pass Filter ventilates the heat away from inside of the transceiver cabinet. This large axial flow fan is mechanically isolated from the chassis to reduce vibration and noise. The speed of the fan is continuously controlled by the temperature of the PA amplifier; starting at 40 degree C.
Antenna Tuner Included
High Speed Automatic Antenna Tuner included. The antenna tuner uses LC switching. It has a large capacity 100 channel memory; the tuning data is automatically memorized to reduce tuning time when changing frequency.
Famous Yaesu Main Tuning Knob
A heavy weighted balanced brass core knob is used to give the famous Yaesu smooth flywheel operating feel to the FT DX 3000D Main Dial Knob. Each user may set his/her favorite torque feeling of the Main Dial rotation.
IF Output
1st IF 9MHz signal with wide bandwidth IF Output available on the Rear Panel for after-market band scopes, CW Skimmer, etc.
USB Capable
USB input included for firmware updates. This input can also facilitates CAT, USB AUDIO IN / OUT and USB TX Control (PTT, KEY and FSK)
Remote Control From A Distant Location
External control (CAT) is possible using USB or Serial Port; this feature means the FT DX 3000D can be remotetly controlled from a distant location!
Big TFT Full-Color Display For Superior Operability and Visibility
The FT DX 3000D presents a wide view angle, high contrast LCD 4.3 inch TFT impressive full color display that provides a convenient view of the radio’s working functions. Superior operability is realized with this convenient display. It permits excellent visibility from different viewpoints. Even with the many FT DX 3000D features and functions, the TFT display makes operation of the radio easy and comfortable. • A Block Diagram Displays RX Signal Path • Choose Analog Type or Bar Graph Meter • Selectable analog type or bar graph type meter indication • Separate Independent Frequency Display • High Speed Spectrum Scope • Bandwidth of the spectrum scope: 20kHz, 50kHz, 100kHz, 200kHz, 500kHz, or 1MHz • TX and RX markers appear during “spit&rdquo ; operation • Level Indicator The function names and the setting levels of the following functions are shown in the TFT main display when a function knob is rotated: Clarifier, Microphone Gain, Speech Processor, SHIFT, WIDTH, KEYER SPEED and CONTOUR • AF-FFT Scope An AF-FFT (Audio Frequency Fast Fourier Transform) scope is built in. This AF-FFT function was first demonstrated in the FT DX 9000 series. With this Scope, the audio characteristics of the received signals; the effect of adjusting the RX IF filter performance; and utilizing the QRM rejection features, may be visually observed. It is also possible to observe the TX audio characteristics of your own signal while using the Monitor function. This is very effective for tuning the parametric equalizer for voice characteristics and the microphone audio. • Spectrum Scope Memory The Spectrum Scope screen can be stored or recalled with one touch. Simultaneously the time information is recorded in the memory, so that the difference in activity may be reviewed and compared, depending on the seasons and times. • Cursor Keys Six keys that are used frequently in normal operation are located at the left side of the TFT display. Other functions can be operated by pressing the "SCOPE" key which changes the "Spectrum Scope screen" to "Function Key Display screen". Even if the radio is turned off, the last operated Key Function is memorized and highlighted.
Top Performing RF Front End
The RF Front End circuit is the most important element because it ultimately determines the HF Receiver performance. Our Yaesu Engineering team has concentrated superior RF Engineering knowledge into the design of the FT DX 3000D front end. • Fifteen separate band pass filters (BPF) are used for front end protection. This effectively reduces the undesired and out of band signals. • In the RF amplifier, the strong bipolar transistor (2SC3357) is used. This transistor shows a low NF, and provides superior intermodulation performance. • The gain of each individual device is kept lower, and the best optimized working point, with the lowest NF, is selected. • A custom-designed wide coverage transformer, with less magnetic saturation, is used for the I/O of the RF amplifier. This construction makes the device performance better and provides excellent multi signal performance.
Down Conversion Receiver and Powerful Narrow Bandwidth Crystal Roofing Filters
The powerful narrow bandwidth crystal roofing filter enhances the receiver multi-signal characteristics. The FT DX 3000D "Down Conversion" receiver construction is similar to the FT DX 5000. The first IF frequency is 9 MHz. This makes possible narrow bandwidth crystal roofing filters (300 Hz, 600 Hz or 3 kHz) with a sharp shape factor that creates amazing multi-signal receiving performance. The powerful narrow bandwidth crystal roofing filter enhances the receiver multi-signal characteristics. • The 3 kHz roofing filter greatly improves SSB signal reception during close adjacent multi signal conditions. • The 300 Hz* and 600 Hz roofing filters provide the best CW receiving environment when the adjacent signals may affect the desired signal reception. *Note: 300 Hz filter optional
