The FTDX-3000D is a dedicated HF rtx, it would be classified a I have a yaesu Ft dx 3000 and when I press to talk after a few seconds the radio shuts off and then comes back - Answered by a verified Electronics Technician Disclaimer: Information in questions, answers, and other posts on this site ('Posts') comes from. The FT-991A is an entry level 'shack in a box', good for beginners and casual operators. New comments cannot be posted and votes cannot be cast.Omni-rig to link to my rig.Yaesu FTDX-3000 FT8 Settings Page. 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 3000 is a solidly packed transceiver ready to give very high performance on all Amateur Radio bands from 160 to 6 meters.Win4Yaesu Suite is a comprehensive control package for the Yaesu FTDX-1200, 3000, 5000, 9000, 101D/MP, FTDX10 and the FT-991 /A. The RF amplier has optimized NF points, and the over-sized wide range RF transformer exhibits minimum saturation in strong signal processing. YAESU pursued the ultimate performance of these circuits. The essential elements in receiver performance are the RF amplier and the 1st mixer.

General Coverage Reception from 30 kHz to 56 MHzYaesu FT DX 3000 Operating Manual. These options are correct as of firmware version V01-25. The following settings need to be changed from their defaults in the menu. A number of menu settings need to be changed to get this radio up and running to it's full potential. This large axial flow fan is mechanically isolated from the chassis to reduce vibration and noise. A cooling fan located beside the final amplifier and the TX Low Pass Filter ventilates the heat away from inside of the transceiver cabinet. A large heat sink is combined with the die cast aluminum chassis for efficient heat dissipation. The RF Final Amplifier produces a clean 100 watt (some modes less)transmit signal. Various easy connections available for RTTY, SSTV, PSK31, JT, and other Digital Modes FM & AM - Wide and Narrow modes included 1st IF 9MHz signal with wide bandwidth IF Output available on the Rear Panel for after-market band scopes, CW Skimmer, etc. Each user may set his/her favorite torque feeling of the Main Dial rotation. A heavy weighted balanced brass core knob is used to give the famous Yaesu smooth flywheel operating feel to the FT DX 3000 Main Dial Knob. It has a large capacity 100 channel memory the tuning data is automatically memorized to reduce tuning time when changing frequency. The antenna tuner uses LC switching. High Speed Automatic Antenna Tuner included. The FT DX 3000 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. External control (CAT) is possible using USB or Serial Port this feature means the FT DX 3000 can be remotely controlled from a distant location!Big TFT Full-Color Display For Superior Operability and Visibility This input can also facilitates CAT, USB AUDIO IN / OUT and USB TX Control (PTT, KEY and FSK) TX and RX markers appear during “spit” operation Bandwidth of the spectrum scope: 20kHz, 50kHz, 100kHz, 200kHz, 500kHz, or 1MHz Selectable analog type or bar graph type meter indication A Block Diagram Displays RX Signal Path Even with the many FT DX 3000 features and functions, the TFT display makes operation of the radio easy and comfortable. It permits excellent visibility from different viewpoints. This is very effective for tuning the parametric equalizer for voice characteristics and the microphone audio. It is also possible to observe the TX audio characteristics of your own signal while using the Monitor function. 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. This AF-FFT function was first demonstrated in the FT DX 9000 series. AF-FFT Scope - An AF-FFT (Audio Frequency Fast Fourier Transform) scope is built in. The receiver RF Front End circuit is the most important element because it ultimately determines the HF Receiver performance. Even if the radio is turned off, the last operated Key Function is memorized and highlighted. Other functions can be operated by pressing the "SCOPE" key which changes the "Spectrum Scope screen" to "Function Key Display screen". Cursor Keys - Six keys that are used frequently in normal operation are located at the left side of the TFT display. 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. The gain of each individual device is kept lower, and the best optimized working point, with the lowest NF, is selected. This transistor shows a low NF, and provides superior intermodulation performance. In the RF amplifier, the strong bipolar transistor (2SC3357) is used. This effectively reduces the undesired and out of band signals. Fifteen separate band pass filters (BPF) are used for front end protection. The powerful narrow bandwidth crystal roofing filter enhances the receiver multi-signal characteristics. 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 first IF frequency is 9 MHz. The FT DX 3000 "Down Conversion" receiver construction is similar to the FT DX 5000. The powerful narrow bandwidth crystal roofing filter enhances the receiver multi-signal characteristics. This construction makes the device performance better and provides excellent multi signal performance.Down Conversion Receiver and Powerful Narrow Bandwidth Crystal Roofing Filters IF SHIFT - With the normal bandwidth, the pass band area can be moved relatively, so that harmful signals are rejected from the pass band Proven IF WIDTH and IF SHIFT functions provide great QRM rejection performance The signal is processed with the high speed 300 MHz clock frequency. The 32-bit high speed floating decimal point DSP, TMS320C6727B (maximum 2800 MIPS/ 2100 MFLOPS) made by Texas Instruments, is used for the IF section of the FT DX 3000. Effective QRM rejection is achieved from the FT DX 3000 IF DSP. The 300 Hz* and 600 Hz roofing filters provide the best CW receiving environment when the adjacent signals may affect the desired signal reception. When the IF Width is turned clockwise from the center click point, the pass band width can be extended wider, up to 4000 Hz. When “NAR” is turned on, the minimum pass band becomes 50 Hz (200 Hz in the SSB mode), making it possible to minimize the QRM with this sharp filter shape factor. When the IF Width knob is centered (click point), the pass band width is 2.4 kHz in the SSB and CW modes. This function is effective in a pile-up or contest, when the undesired signals are located just above and below the target signal. The IF width function can make the pass band narrower with one-touch. Different from the IF SHIFT or IF WIDTH, the special CONTOUR pass band, can reduce or peak the desired signal, partially and continuously across the pass band. The CONTOUR function varies the outline of the IF DSP filter pass band characteristics, and the in-band signal construction can be partially altered. CONTOUR - The CONTOUR function ideally tailors the received audio signal without changing the bandwidth. The desired signal components are peaked and the random noise components are effectively cancelled. The noise reduction constants may be set to the optimal working point by varying the 15 step parameters according to the actual noise within the HF band. Digital Noise Reduction (DNR) by DSP - The installed digital noise reduction circuit provides 15 separate parameters.
