The Alinco DJ-X11 even with it’s shortcomings has been a neat little hybrid wideband receiver with SDR capabilities. The DJ-X11 is a decent little receiver on it’s own, but when used with SDR software it gets even better. However, Alinco sort of dropped the ball when it came to developing a dedicated SDR software package for the radio. There was an initial very simple free package that had some basic features, but it now seems absent from Alincos website. You could use most standalone SDR packages to to use the Alinco DJ-X11 IQ output for SDR, but you were stuck having to set the center frequency by hand on the radio. Needless to say this was a bit of a pain, since the DJ-X11 had the capacity to be controlled via it’s computer interface. Thanks to Michael that is now a thing of the past. He has written an ExtIO plugin that will work with HDSDR and possibly other programs that support ExtIO radio programs. The ExtIO plugin allows HDSDR to tune the radio from it’s tuning controls or by clicking on the waterfall display. I tested out the plugin with the Alinco DJ-X11, ERW-8 interface cable, and HDSDR. Everything seemed to work very well. During the test, I was pretty impressed that HDSDR could dig out weak CW signals on 20 meters using the included rubber ducky. Normally on the DJ-X11 without some type of larger antenna on the HF frequencies you normally will just hear static.
To set this up:
- Download the ExtIO file.
- Download and install HDSDR.
- Extract the ExtIO file to a folder.
- Using a text editor, edit the ini file contained in the HDSDR DJX11 folder to reflect which com port your EWR-8 cable is using.
- Copy the the .ini and .dll file contained in the HDSDR DJX11 to the folder you installed HDSDR into.
- Plugin a stereo patch cable to the DJ-X11 IQ earphone jack and to your sound card line in jack.
- Put the DJ-X11 into IQ mode and place it into the cradle.
- If you did everything right you should be good to go.
Note – The ExtIO worked fine in HDSDR, but I could not get it to work with SDR Sharp which supports ExtIO files. It was the .dll file fine, but could not open the port. This may have been an issue with SDR Sharp or just an issue on my pc.
