00:27 < saxo> Looks like the @IEEESpectrum article on the KrakenSDR's passive radar software got them hit with ITAR restrictions. All Passive Radar code has been pulled (of course i'm sure forks exist... it was open source after all). https://forum.krakenrf.com/t/where-has-the-passive-radar-code-gone/98/3 https://pbs.twimg.com/media/FhaZ1FfVUAAnAj_.jpg (@vk5qi)
00:28 < nmz787> git clone while you can, folks!

05:24 < kanzure> nmz787: need passive radar for something?
06:43 < superkuh> No need to do it with Kraken boards (many rtlsdr on a board with a board to inject noise into all of them at the same time to try to roughly align and get coherency). You can do bistatic passive radar with a single rtlsdr. https://dopplerfish.com/passive-radar/
06:45 < superkuh> See also, http://kaira.sgo.fi/2013/09/passive-radar-with-16-dual-coherent.html
07:07 < superkuh> Just to be clear, it requires 2 single (ie, not on the same board) rtlsdr. 
07:08 < superkuh> But yeah, the software is there on github still.
07:08 < kanzure> "This is a nasty attack against python developers. There are a bunch of packages with the wrong name “ipyhton” instead of “ipython” which will drop a malicious JS into your environment which then replaces any copied address from your browser to one of the ones designated by the hackers."

07:48 < L29Ah> this one requires 2 rtlsdrs modified to use a single clock
07:51 < superkuh> <superkuh> Just to be clear, it requires 2 single (ie, not on the same board) rtlsdr. 
07:52 < superkuh> But yeah, that was very unclear phrasing by me.
07:52 < L29Ah> i wouldn't call them single now :]
07:53 < superkuh> Just a piece of wire from one to the other and popping off the clock crystal on one.

08:04 < kanzure> superkuh: are there any other interesting SDR libraries that we should know about?
08:04 < kanzure> besides gnuradio
08:07 < superkuh> The other big one is soapysdr I guess. 
08:08 < kanzure> latest commit to soapysdr seems to be... by the son of the previous gnuradio maintainer?
08:08 < kanzure> alrighty.

09:21 < nmz787> kanzure: not really, could be cool though to map out airplanes in my area just as a project with my kid someday, idk
09:21 < nmz787> probably not useful to detect aerial spraying from helicopters or crop-duster type airplanes
