I would like a friend to send me files that OP25 can read. Per the documentation, scope.py
requires standard complex IQ format files at 96K rate:

File Playback Example

Selects input from a file instead of RF capture device. The file must be in standard complex (I/Q) format at a sampling rate of 96,000 Hz. Playback should automatically restart from the beginning whenever EOF is reached.

./scope.py -F ~/gr/capture-96k.dat -g 10

What is the best way to record in this format?

thanks!
Joe
