Over on his blog, Thierry Leconte has been writing about some IF bandwidth experiments that he's performed on the R820T2 chip. This is the tuner chip that is used in most RTL-SDR dongles, and well as on the Airspy R2 and Mini SDRs. It has a programmable IF bandwidth and high pass filter which can be used […]
