Hi Mark and Aylons,
I’ve also wondered whether a cheap RTL-SDR could be used with GnuRadio
as a multichannel analyzer for a homemade Gamma Spectrometer, either
using a Geiger tube or a scintillator. I think the tuner would need
to be bypassed so that the sampler can get direct samples. There’s
info on a direct sampling mod here:
I’ve also been curious about using GnuRadio for analysis of other high
bandwidth signals, for example from magnetic field detectors such as a
Definitely let us all know if you try this out or come up with other
interesting non-radio instrumentation applications. There are so
many interesting possibilities!
data the latter mainly deals with transient pulses.
