I saw from your other thread that you were channelizing and decimating, and I assume you are logging this to disk for extended periods. I'm doing a similar thing here: https://github.com/madengr/nbfm_rec Although I'm not using a channelizer, only because there is no band plan for what I was reco

Hey Lou, That's a very interesting approach, I'll look into your example as well. Thank you very much! Best, Ali On Wed, Mar 11, 2015 at 4:39 PM, madengr wrote: > You can also use probes to bring out the data asynchronously from the flow > which you can then process in Python. For example, yo

You can also use probes to bring out the data asynchronously from the flow which you can then process in Python. For example, you could probe at a 10 Hz rate, then have your Python script log those values to a file, or trigger some other event. I have an example here where it probes the signal le

Hey, I can't tell you how you should do this. I can tell you that you will need to get comfortable with tags and probably messages to achieve these things you want. If you haven't already, check out the gnuradio tutorial on programming topics to get started. They do a pretty good job explaining it

Hello everyone, So I was trying to capture continuous IQ data from my USRP N200, and this needs to be done for about a week, but because the amount of data is ginormous, that's doesn't seem feasible at all. Instead, what I'm now thinking of doing is processing the data in gnuradio companion in rea
