Re: Suggestion how to multiplex 2 IQ-streams?

See https://github.com/jmfriedt/passive_radar in the dual_rtl_sdr.grc
where you can replace the File Sink with ZMQ Pub. Be aware though that
despite being syntonized (same clock source ?) the two streams are most
probably not sychronized as the two USB streams start at random time,
but this time offset remains constant as long as the ZMQ-Pub is not
stopped.
