E4000 USB DVB-T + RTL-SDR Realtek RTL2832U + R820T DVB-T Tuner Receiver PAL IEC
1.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. So far the tuner driver comes straight from the kernel driver that Realtek supplies, and setting gain manually is not supported yet, although functions for that seem to exist. There is still is a lot that needs to be done, the best thing most likely would be to completely rewrite the driver, or at least clean it up dramatically. Initializing the tuner takes way too long at the moment, since the driver produces a lot of I2C traffic, most of it being redundant as it seems.
