Geof:
You were right, and I installed the Intel x64 Fortran package available
here:
https://software.intel.com/en-us/articles/redistributable-libraries-of-the-intel-c-and-fortran-compiler-for-windows
Unfortunately, I'm now getting python.exe crashes when launching GnuRadio
Companion. I'll try re-installing tomorrow and getting back to you.
Martin:
Sorry for the late response. I was (roughly) following the receiving end
of this tutorial:
https://oshearesearch.com/index.php/2015/05/31/building-a-burst-fsk-modem-in-gnu-radio-with-message-lambda-blocks-and-eventstream/
The list came from something I built from the Windows package. The rtl_sdr
source in particular came with the default install and I didn't think much
of it. Where would I find something like the rtl_sdr source in Linux? I'm
connecting to an rtl_tcp server on my router. I can try PyBombs again, but
it sounds like it won't fix my main problem.
Thank you both for getting back to me!
