I received my readybuilt card today, and put it into operation. Compared it to my ICOM R-71 receiver. Amazing, my ICOM gives a little bit better S-meter reading, but nothing else differs. You have produced a very good software receiver. Thanks a lot.
I did some test on different computers and realized that the soundcard quality is very important. Best performance I got with my Delta 44 card. The antenna is also very important. Tried it with a short (2meter) wire, no good result. Running on my 20 meter dipole gives excellent result.

I've just put an order in for one, so will be watching for the post arriving next week!

I was going to get an SDR-IQ but they always seem to be out of stock. I know the Elektor unit is 150kHz - 30MHz, where as the SDR-IQ claims to go much lower, but at least I'll have something I can have a play with.

Have a look at what we've done to extend to VLF and ELF -- see pages 46 - 52 in Elektor September 2007.

Interesting about the need for a good antenna. This implies that the input sensitivity is down on a normal radio. I have tried the Perseus and found it about an s point down on my FT847.
Now with the sound card being so critical, the results will vary. Has anyone looked at the general figures for noise, image rejection compared with the Perseus or any standard radio like the FT series?
I cannot find anywhere a spec on the basic board.
I have a Roland 24bit 96KHz stereo box that I plan to hook up to the board. Also running the G8jfc software and it currently seems to run fine with the Roland -just waiting for the board to be delivered.

I am interested in the SDR board/kit. Does this contain the USB interface? I read the PDF article, but wasn't sure if the USB port is something extra on the kit being sold.

Any other hardware needed, other than a test of my sound card??
