I'm not sure that I've got the question, but in any case here are a
couple of answers:
If you've got an external program that implmenents a GMSK modulator,
the easy way to get its output in to GNU Radio is to have the external
program create a binary file containing either shorts of floats. Then
use either VrFileSource<short> or VrFileSource<float> as your source
(head of the pipeline in GNU Radio).
If I got the question wrong, and what you want to do is take the
output of GNU Radio and pass it to an external program, the process is
to create a binary output file with GNU Radio using either
VrFileSink<short> or VrFileSink<float> and then feed that binary file
to your external program.
Unless the data sets are huge (100's of megs), I suggest that you use
floats as your external file format. It's just less hassle to work
with.
Hope that helps!
