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.
The driver originally had a frequency limitation of 40 MHz to 900 MHz,
but tests showed that the PLL of my stick can achieve lock up to 1766
MHz, and indeed both ADS-B at 1090 MHz and L-Band DAB at 1463 MHz, as
well as GMR at 1556 MHz can be received just fine with the R820T.
Also, the PLL could lock again at 1850 MHz to 1860 MHz, and the
reception of a GSM 1800 BTS at 1854 MHz worked as well.
Some initial comparisons [1] between the E4000 and R820T seem to hint
at the R820T being a bit more sensitive, especially visible in the
Tetra screenshots.
Given that the supply of E4000-based sticks is dwindling, Im pleased
to see a new tuner that has the potential of becoming a good
replacement, and staying for a while on the market.
Note: 1.Before you buy please confirm whether the local DVB-T signal 2.United State and Canada can not use the DVB-T function（local without DVB-T signal）,but the other functions can be used.
