Re: [Discuss-gnuradio] making signal source based on a certain format

[Michael Piscopo]

I ran into a similar issue a few years back and wrote an updated file block with some enhanced features.  It's up on github here: https://github.com/ghostop14/gr-filerepeater.  Not sure if it's an exact match for what you're looking to accomplish but you can specify delays between replays and tie it into a mute block to "go silent".  There's a couple of example flowgraphs in the examples subdirectory.  See if it helps.

Hi Linda,

Do you mean "sending 0 in between" or do you mean "switch transmission
on some SDR device on and off"?

First case: multiply with a (threshold(sawtooth from signal source))

Second case: see the gr-uhd examples on how to do bursty transmissions,
if a USRP is what we're talking about!

If possible, when asking the mailing list, give enough context so that
we can unambigously understand what you're asking about!

Best regards,
Marcus Müller
