BBC DRM on RTL2832 Up converter -VU2IIA

http://tiny.cc/0pjtvx Best sale ever made by Tune4mac
BBC DRM recieved using my experimental Up converter, it uses 30mhz LPF with preamp having adjustable gain on HF band. HF signals are mixed with 40mhz crystal oscillator using SRA-1 mixer, output from mixer is BPF and buffered to remove any unwanted mixer products. Up works from 1 MHz to almost 30Mhz. Necessary offset / shift is given in Sdrsharp program, making tuning very easy. Using this up converter I have decoded SSB PSK and SSTV signals.
