Equipment / Re: good sdr to catch most of the shortwave pirate spectrum?
« on: Today at 21:50 »you can run multiple instances of SDR Sharp, I do that occasionally.
I think that you know this already but for others' benefit, related to that, SDR Sharp will allow you to run what amounts to a second receiver, that they call a "slice", at the same time as the first.
As long as the "slice" is tuned to a frequency within the main receiver's bandwidth, and presumably the slice's bandwidth does not extend outside it either, you can have what amounts to a second receiver. This is a bit like a second VFO but the difference is that you are receiving both at the same time instead of having to switch between the two. Of course, since the HF Discovery+'s bandwidth is limited to something like 500 KHz (I forget), you can't be listening to, say, 11 meters and a pirate on 43 meters at the same time. That's where you would need a second receiver.
I don't even know if there is a software-defined limit to how many "slices" can be running at once, so you might be able to run more slices than just one. However, I'm sure that there a practical limit, as "slicing" takes up processor time and USB bandwidth. Eventually things will start to slow down and you will start to notice gaps in audio, etc.
