![]() However, the PLL chip we used originally is no longer made, making it necessary to find a new solution. In the meantime much thought has been devoted to conceiving updates for this design. ![]() A Software Defined Radio with USB interface was introduced as long ago as 2007. That just has to make you curious!Įlektor has already published many radio and receiver projects. And there is always something new to find, from pirate radio stations through SSB radiotelephony to the new digital modes. On some bands it is the radio amateurs who produce the strongest signals. In fact it is often so quiet on the short waves that it’s easy to imagine your receiver has gone deaf. ![]() Now more than ever you might say, because many distant stations now come up far more clearly because they are no longer swamped by stronger signals. ![]() Supply voltage: 5 V and 3.3 V as for Arduino Įven though broadcast services are deserting the AM domains in the long, medium and short wavebands, there is still plenty of interest to be found surfing the radio waves with a home-constructed receiver.The characteristics of the receiver are defined in software, which now gives us the opportunity to use an Arduino Shield as a front-end. Elektor SDR Reloaded SDR Shield for the Arduino By Burkhard Kainka (Germany)Ī Software Defined Radio is a universal tool in RF technology circles, one that can also be put to use for making measurements.
