Alinco SR-9 100W HF Transceiver with SDR Technology
Here is an interesting new transceiver that embraces SDR technology and resukts in a budget class radio with surprisingly competivie performance and loved by those who have used it.
Very strong in the CW department, the DX-SR9 features an on board electronic keyer, and a narrow filter.
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.)
- 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, and band selection
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)

- 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
- 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
- General coverage receiver 150kHz -30MHz
- All modes AM/FM/CW/LSB/USB and SDR
- Built-in electronic keyer for excellent CW performance
- Internal VOX eliminates optional interface box for PC connection
- Rugged, die-cast chassis and huge LCD display
- Front mounted speaker and powerful 2w audio output
- Front and rear jacks make PC interface easy
- Narrow ceramic filters (500Hz CW / 2.4kHz AM / 1kHz SSB)
