Re: [Discuss-gnuradio] Recording Probe Rate or other Messages

[CEL]

Hi David,

this would be an easy task for a four-lines-of-actual-code Python
block.

However, as much as I like GNU Radio (you'll find I like it a lot), is
this really a GNU Radio job? Your rate is proportional to the speed at
which your file is read, and you could do easy things like making a
named pipe (`man mkfifo`), use that in your file source and using `pv`
to feed that from a file, or something similar.

Best regards,
Marcus
