Ensemble II RX
Another SDR receiver !?!
This is the Ensemble II from Tony Parks. Had a bit of a blitz on this one the last week and went from bareboard to finished item in about 6 hours of on and off work in the evenings. Apart from putting the final I Q op amp in the wrong way round, it went quite smoothly. Lucky I have a SMD desoldering iron, and I had not damaged the op amp, so the board fired up when I rectified the mistake. Now I just have to start the V6.3 RX/TX, thats been under the bench since March of 2010. I have more motivation now as a SDR-2-Go board should be arriving soon from K5BCQ, and that allows the 6.3 (and other SDR boards) to become standalone units, no need for a computer.
The case in this picture is from Tom K5MH.
Frequency control is via USB and an SI570 running software from Fred PE0FKO (CFGSR) under HDSDR software on an XP computer.
