Thanks Marcus,
Concerning your points, I thought I’d edited the Subject line to
start a new thread. I’ll be more careful in the future.
Also thanks for your clarification of the source code origin. I’ve also
directly contacted the folks at SDRPlay.
I do think the SDRPlay folks do want to be more closely integrated
with the Gnuradio folks, as they are partially integrated into
the OsmoSdr releases. I’m a little vague on the relationship
between OsmoSdr.org and Gnuradio. Maybe the relationship is
“parallel play”.
Thanks again,
Glen
