Alinco DX-SR9 is a hybrid, stand-alone, analogue and digital Software Defined Radio (SDR) transceiver. Although quite advanced, its simple operating commands, straight forward and logical key layout assures that you can start enjoying this state-of-the-art transceiver from the moment you first power up!

With front-panel separation, large bright LCD screen, front-facing speaker, built-in keyer and many other desirable features, Alinco DX-SR9 is ready to capture the attention of everyone from a beginner to the most experienced ham operators!

Detachable front control panel. A completely detachable front control panel with a large LCD display lets you install the radio with greater flexibility whether in your car, boat or your shack. (Optional EDS-17 cable required).

 

Direct DATA entry via the keypads. While the main dial tunes at the default 10Hz/resolution (adjustable in set mode), the numerical key pads can be used for fast direct frequency input, band selection and more.

Coverage of All short-wave and HF amateur bands: Covers the 160 m to 10 m amateur bands including 5.3 MHz in SSB, CW, AM, FM and IQ output modes. Output power is 100W SSB/CW and FM, 40W in AM with low and super-low power settings for QRP operation. In addition, the general coverage receiver covers 135 KHz to 30 MHz in all modes. (The RX sensitivity and selectivity are not guaranteed outside of the ham bands).

World-class transmit audio quality. A dynamic microphone (T/E models) and a speech compressor come standard for sharp, clear and powerful transmitting audio.

Internal VOX. Eliminates optional interface box for PC connection to operate data modes like PSK31. )

Additional convenient features include. RF Attenuator and Pre-amplifier selectable in 4 steps, / 3 TX power output levels with a Super-Low setting (QRP 0.1W~2W variable) / Dual VFO / 600ch memories in 3 banks / Connections for Auto-antenna tuner and Liner amplifier ALC output / Fully independent AF level, squelch, RIT and IF shift knobs / Dial lock and key lock / TX-RX lamp / Alphanumeric display / Auto-power-off / CTCSS encode for 10m FM repeater accesses / Microphone, Headphone and External speaker jacks on the front panel / Large, temperature-controlled internal cooling fan with anti-overheat output power limiter/ High-SWR protection and more!

Fight QRM with these STANDARD features. Reject unwanted signals with the IF shift. Choose a narrow filter(AM 2.4 KHz/SSB 1 KHz, CW 0.5 KHz audio-filtering), a noise-blanker or use RIT/TXIT to stay out of QRM.

 

Emphasis on CW Operation. An electronic keyer unit is standard. You can receive CW using either the upper or lower side of the carrier frequency. Choice of side tone pitch, FULL (QSK), Semi or Auto break-in, split, narrow filter, AGC and RF gain.

 

Enhanced scan modes. A variety of scan modes are available including Priority, Search, Busy, Timed, Memory and Programmed search. The timed scan setting does not require a squelch-mute so you are able to monitor data modes and broadcasts simultaneously with the memory search scan.

About SDR

The SDR system in DX-SR9 consists of an I/Q signal output and a mixer circuit. It requires a high-quality sound device (internal or USB-interface) and PC specs as follows. Please remember, the Higher the PC spec, the Better the SDR performance!

  • OS: Windows Vista or 7
  • CPU: Intel Core i5 2.4 GHz equivalent or faster
  • Memory: 2 GByte or more
  • Display Resolution / Colour: 1024 x 768 pixel A32 bit or more
  • Sound Device: 48 KHz 16-bit sampling, capable of stereo record/replay (Tested with Creative Sound Blaster Series)
  • Mouse: Center wheel and High-speed scroll feature
  • Cables: A pair of commonly available audio cables with a 3.5 mm stereo-plug
  • PC Speaker, PC microphone or headset (with microphone)
