Dear List,

 

I just received the NooElec R820T SDR USB dongle with antenna to test some of my GNU Radio code. This particular dongle uses the R820T SDR. Does anyone know if osmocom supports it, or if it works at all?

 

I see that osmocom supports

http://sdr.osmocom.org/trac/wiki/rtl-sdr#SupportedHardware

 

 

The code below shows that the rtl_test program detected the tuner, but failed because it =! E4000. Is that the only tuner currently supported, or is there a command-line flag I can use to toggle tuners?

Most of the "stuff" in rtl_test is intended to test specific features of the E4000, but the librtlsdr drivers and gr-osmosdr *do* definitely support the R820T -- for a few months now.
