USING CARD: ID 15f4:0133 HanfTek
You need modify source code to get this one working(add ID), and you need https://github.com/mutability/rtl-sdr/ this driver, the original driver frequency is NOT WORKING RIGHT!
use linux, on windows dont even think about it. i use rtl_tcp as server and connect windows to linux pc :)
This card has rare tuner chip: R820S instead of T version. it work fine.
frequency goes about 14 - 2000 MHz (about) PLL still locks on 1mhz and 2,4gz.. so not sure if they work
