Software Defined Radio Diy. Ranging from the popular low cost and simple to understand SoftRock SDR hardware up to the modular and incredibly flexible High Performance Software-Defined Radio HPSDR project that I first wrote about in November 2010. But there is a huge drawback.
But there is a huge drawback. So if you are looking for a solution which covers HF frequencies a DVB-T. When valves came along tubes for our American friends they made it possible to build much more.
But it needed a long aerial and could only receive local stations.
It is a software defined radio meaning that it uses a computer to control the radio to demodulate the signals received and to modulate the signal transmitted. At last the technology exists to turn your computer into a super radio receiver capable of tuning in to. So if you are looking for a solution which covers HF frequencies a DVB-T. I used a random wire antenna outside my balcony and connected it to the center-pin of a car antenna mount and used a long coax to guide the signal in the room to my DIY low-pass filter then connected it to my DIY SA612 mixer and its output to my RTL-SDR and.
