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

Broadcast from the top of Mt. Umunhum. Was very surprised at the accuracy of the RTL dongle. I am using unamplified rabbit ears to pick up the signal. – Source

Testing out the EzCap EzTV668 that has the RTL2832 and the E4000 Tuner Chip. I think it’s much better that the FC0013 Tuner. However don’t take my word for it. For $20 you can’t complain either way at 00:40 you will hear a conversation on a local repeater (W1TOM 146.940), One of the stations is close by my QTH and with the 2Mhz sampling, you can see both the output of the repeater and the -600khz input from the operator. – Source

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
