Web SDR

As an update to my introduction to Web SDR, I have noticed a growing number of KiwiSDRs that have 20 kHz of IQ bandwidth. This gives much more scope for experimenting with DSP and are worthy of further investigation.

In the example shown you can see the capture BW, under the green marker, with numerous CW signals that would be interesting to separate out individually using filtering and frequency shifting. But there are enough signals that you could also experiment with decoding mutiple signals simultaneously along the lines of CW Skimmer.

What is interesting is that you to grab a useful chunk of spectrum to then process it either to extract interesting signals, or experiment with DSP to process these captured signals further.
