How to run gnuradio application with a file input and no physical receiver?

Hello and thanks for your guidance:

I would like to run the gnuradio software package with an input file and
other input data.

So far, when I run examples in gnuradio-examples the application stops
because no USRP is found.

A short term goal is to learn about the process of digital signal
recovery. The long term goal is to use input data from a breadboarded
digital radio gadget.

Thanks again, Lee McKusick

Try using the audio examples, or bypass the examples all together and
use gnuradio-companion to setup your signal flow. Feel free to change
the audio sources from those examples and replace them with generated
signal sources.
