Getting raw IQ data via GNURadio
Posted: Wed Jun 12, 2019 6:44 pm
I have an RSPduo and I am trying to accomplish something that seems relatively simple - just dump the raw IQ data from the two SDRPlay RSPduo channels into two separate files. I installed the source blocks using this: https://www.sdrplay.com/gnu-radio-and-s ... onvention/
However, there is no documentation on how to proceed. I have tried connecting my duo block to two separate file sinks (since all I need is the IQ data, no demodulation or anything). However, many of the RSPduo settings are pretty esoteric and I can find no explanation for what they should be, namely - AGC? IF attenuation? LNA Attenuation Step? BiasT?
Further, connecting the duo block to a file sink is not possible for some reason. I don't have qt GUI installed, but I shouldn't need it for this simple application.
Thank you for any help!
