   So kind of like those TV USB sticks that you can adapt into proper SDRs?

      Yep, Matt Ettus converted that to hundreds of millions of dollars

         the Ettus USRP SDRs predate RTL-SDR by almost (not quite) a decade.

            I was always into the soundcard HF SDRs, they were so simple and elegant. An oscillator, a ring counter, a 4052 MUX and one really fast dual opamp.

               This sounds interesting. How do they work, or where can I learn more?

                  The very original: <a href="https:&#x2F;&#x2F;www.wb5rvz.com&#x2F;sdr&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.wb5rvz.com&#x2F;sdr&#x2F;

                  I have a couple of Kanga Finningley SDRs bought through the G-QRP club, but they appear to have almost entirely vanished from the Internet.
