Actually there’s no longer any need for a PC and sound card. Or you might say that the “PC” has now shrunk to the size of a cell phone. See my web site: http://digitalconfections.com.

Hey Greg!
Thanks for your comment! Indeed, I mixed up QSE with QSD. I just corrected it in the post. Thanks again for the notice!

The article states “The QSE mixes the RF signal into a baseband signal” when in fact a QSE does just the opposite. A Quadrature Sampling Exciter takes I and Q baseband as its inputs, and produces RF as its output. With the lofty title of “Do you truly understand the SDR concept?”, I would expect the author to do so.

Interesting site and I will bookmark it for future reference and education. I’m amazed by the excellent signal to noise (to my ear) characteristics of SDR on PA3FWM’s receiver. Got a shack full of old stuff (Drake 2b/Collins KWM2/etc) and newer gear (IC756/FT857)…but the NEW stuff (SDR) has me excited about the future of the hobby and the advances technology can bring.

Much work has been done (and continues to be done) in the amateur community focusing on the RF and signal processing portions of the SDR. The user interface is lagging behind. Keyboards as input control devices are not optimal. As a UI for tuning in a radio signal, you can’t beat a knob as a man-machine interface. Yes, there are some knobs out there, but the potential, and acceptance, of the SDR will occur when we can customize the UI as easily as the other elements.

Very good piece, Tobias.

Hi Tobi, thanks for this very interesting article. I hope to get my Softrock SDR working as soon as possible to expore SDR by myself.
