This helps a lot. Thank you. I hope I'm adding this reply to the list correctly.

Thank you for responding. I'm still new to GRC, so I don't know how to go about doing that. Would I have to write a .py file? Then how would I import it to GRC?

Please keep replies on the list.

So I was about to reply something along the lines of "It's just Python, you can figure it out," but then I realized that we provide a good mechanism for handling this; it's just not well exposed. So I wrote a tutorial on it this morning:

Hope this helps.

I am having trouble reading a file and putting it as a variable or some way so that the USRP Source block will read it and evaluate each item. I'm using a file source and i tried connecting to a message sink, but I'm stuck there because the output of the sink does not match the input of the USRP Source. Is there a way to have a txt file read and put into a array of some sort to be evaluated?

 

The file source block reads binary data that it converts to stream of samples.

What you want sounds like you could write a simple Python function to accomplish.
