The hardware device driver for Windows is via Zadig, similar to how the RTL-SDR driver is installed. Otherwise on the SDR software side....

The ADC is a 14-bit version of the LTC2143.

It seems you can likely select spectrum in either 100kHz-25 MHz direct sampling or 25MHz–6GHz superhet modes, though I suspect perhaps not an overlap of those two ranges. Not sure here, so a big YMMV on my part.

Spotted a post on another site suggesting a $395 MSRP. Potentially an even bigger YMMV.
