Downconversion and Filtering
This video shows the progress made on Cocoa Radio since the last video. The spectrum that is visualized in the waterfall and graph is AFTER the downconversion mixer and FIR filter. As I move the red line (software tuning) around on the display, it changes the tuning of the downconverter, and you can see the spectrum change. Also, when I change the IF bandwidth, you can see the effects of the filtering. There’s still quite a bit of work to be done, but these results are encouraging. – Source
NT1K.com – RTL-SDR W/ RTL2832U & FC0013 Tuner
Messing around with a EzTV645 W/ the RTL2832U and FC0013 Tuner Chip. Software being used is SDR# (SDR Sharp). I’m having some issues like getting mixed FM boardcast signals no matter where I’m at and multiple images of the same signal. I was told this was normal but I messed something up while soldering in a pig tail to replace the current RF connector. Too sensitive to ESD See for more information – Source
