Sticks with this combination (RTL2832 + R820T) are relatively new on
the market. The main difference to all the other supported tuners so
far is that it uses a Low-IF (3.57 MHz) architecture instead of
Zero-IF. That means the tuner is only connected to the In-Phase ADC
input, and the internal down converter of the RTL2832 is generating the
complex samples. This has the benefit of having no DC offset spike in
the middle of the spectrum.

USB Tuner that can extract up to 3MHz of radio spectrum from anywhere between about 40MHz and 1.7GHz in 8 bit I/Q and poke it down USB for use by a software defined radio (WinRad, HDSDR or GNU Radio).
The Hama Nano is supposed to be a DVB-T dongle, but an undocumented feature in its Realtek chipset opens it up as a general purpose tuner sending raw samples to a software radio.
