Re: [Discuss-gnuradio] Transmit and Receive hopping Sequence in FHSS (using gr-spread module) mismtach

Hi Marcus, I am not using frequency aligning. I think your guess about "frequency offset" thing is possible. Since we are never transmitting on -187Khz but we do observe a signal over there. The received signal that we observe is just what is being transmitted. We are not applying any

Correct me, but this is 400kS/s – that should really not max out anyone's system, unless the spread blocks are really terribly inefficient (I don't think they are); please check this, though! If I'm not mistaken, gr-spread doesn't tune the hardware or anything – it just creates a continuous phase

I have had issues with scheduling transmissions at ~ 10 ms per hop and ending up with transmissions happening on the wrong frequencies. Usually it's one channel off. If you slow the system down does everything work properly? Also, are you pegging out any single core in your system? I have seen

Dave, Thanks for replying. we are hopping every 80ms. ᐧ On Fri, Aug 26, 2016 at 12:32 PM, Dave NotTelling wrote: > Ajinkya, > > How fast are you hopping? I've had loads of issues with hopping > rapidly and not having the correct frequencies used. > > -Dave > > On

Ajinkya, How fast are you hopping? I've had loads of issues with hopping rapidly and not having the correct frequencies used. -Dave On Tue, Aug 23, 2016 at 7:16 PM, Ajinkya D Kadam wrote: > HI All, > > I am using gr-spread >

Re: [Discuss-gnuradio] AUTOMATIC START AND STOP FILE RECORDING

You can dynamically change the name of the file sink while the flowgraph is running. For example, you would change it from "/dev/null" to "~/my_data.bin". You would start the flow, then in python loop, wait so many ms, poll the time, then change the file sink name. Lou Ernest wrote > Hi All,
