Re: [Discuss-gnuradio] How to import in Gnu Radio IQ.wav files recorder with SDR#?

[Jeff Long]

You need an ishort-to-complex block after the file source. The file 
source does not convert for you. If that doesn't work and your data is 
definitely good (and not too short), then no idea.

Please send replies to the list.
