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.
