Please copy the list next time so other folks can respond besides me.

Just attach a file sink to the ishort to complex block. There’s also a command-line tool called gr_fileman in gr-analysis [1] which will do this, but the file needs headers. If you don’t have them, you can generate with gr_mkheader in gr-analysis.

Hope this helps,

Now, how can I convert this to a CFILE format where I can play it in Gqrx? Thank you

Use a file source block with “short” type into an “Ishort to Complex” block. The Ishort to Complex block will de-interleave the shorts into complex samples.

Can someone advise a bit?
