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 [1]

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.

Excellent! Thank you. It seems to work.

Try rtl_test without any options.
The -t option is for benchmarking the E4000 tuner.
