Multiple VFO (tuner) using the SDRPlay

There's a really cool program I recommend using with the SDRPlay called SDRConsole. It supports a feature called Multi-VFO.

I had heard of Multi-VFO but thought it was a hardware feature only present in the most expensive SDR's. But with SDRConsole, you can actually tune in multiple stations at once in software! This is useful for listening to walkie-talkies that transmit and receive on different frequencies, or even hearing multiple police walkie-talkies at once.

The only downside (for me) is that SDRConsole doesn't use the standard EXTIO interface, but rather the Mirics API. This means you don't get all the nifty SDRPlay options like RF Gain vs Use AGC, or most importantly, the DC cancellation options.
