Hi all: I teach a course at USC on satellite ground communications
that is a lab-based class.
I would like to setup an intermittent transmission using a recorded
beacon that we have used before (in cfile format) to have them practice
“catching signals” using lab Spectrum Analyzers and SDRSharp tools in
the lab. I can get the beacon transmitting continuously with its
recorded waveform, however am not familiar enough to figure what block
structure to use to only intermittently transmit this signal every 10 or
20 seconds. Might there be some easy way to do this? Am using osmocom
to transmit via bench top HackRF in closed lab room, with a cfile recording.
Hi David,
One possible solution would be to make a flowgraph that plays the file
once. Then make a bash script that loops, calling the flowgraph and then
sleeping for some time.
Best,
Daniel.
