Features of DX-SR9

  • Coverage of All short-wave and HF amateur bands
    Covers the 160m to 10m amateur bands including 5.3MHz 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 135KHz to 30MHz in all modes. (The RX sensitivity and selectivity are not guaranteed out side of the ham bands.)
  • Internal VOX
    Eliminates optional interface box for PC connection to operate data modes like PSK31.
  • Detachable front control panel
    Completely detachable front control panel with 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 key pads
    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.
  • Fight QRM with these STANDARD features
    Reject unwanted signals with the IF shift. Choose a narrow filter(AM 2.4KHz/SSB 1KHz, CW 0.5KHz 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 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.
  • World-class transmit audio quality
    A dynamic microphone (T/E models) and a speech compressor come standard for sharp, clear and powerful transmitting audio.
  • Enhanced scan modes
    A variety of scan modes are available including Priority, Search, Busy, Timed, Memory and Programmed search. Timed scan setting does not require squelch-mute so you are able to monitor data-modes and broadcasts simultaneously with memory search scan.
  • 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!
[About SDR]
The SDR system in DX-SR9 consists of 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; Higher the PC spec, Better the SDR performance!

OS: Windows Vista or 7
CPU:Intel Core i5 2.4GHz equivalent or faster
Memory: 2GByte or more
Display resolution/color: 1024x768pixel?A32bit or more
Sound device: 48KHz 16bit sampling, capable of stereo record/replay (Tested wit Creative Sound Blaster series)
Mouse: Center wheel and High-speed scroll feature
Cables: A pair of commonly available audio cables with 3.5mm stereo-plug
PC Speaker, PC microphone or headset(with microphone)

BEFORE you decide to purchase DX-SR9, please download the KG-TRX SDR software from the link below. Please read the included instruction manual and start the program to understand how it works. If it may not satisfy your demands for SDR operation, just delete the downloaded file to uninstall. Alinco and its distributers are not responsible of compatibility troubles with your PC systems.
