We wouldn’t want it to fall into the
wrong hands, that’s for sure! Who knows SDR equipment might get donated to the local Makerspace and they wouldn’t have thought about the consequences. I don’t think they should
be denied their tax deduction, though. They had no way to know…

Subject: [FRIAM] IMSI catchers
Lovely article this, http://www.bloomberg.com/news/articles/2016-03-10/what-happens-when-the-surveillance-state-becomes-an-affordable-gadget.
The LTE network was supposed to be secure against IMSI catchers like StingRays and DirtBoxes, then Harris figured out how to knock the phone back to a 2G connection and all the 4G security went away. And the price to replicate the $400,000 commercial version
as a DIY instrument is quoted as $1,500, though I didn't see any pointers to how to articles. But that is basically the cost of a low end SDR (Software Defined Radio) transceiver that can operate on the cell bands.
So everybody is catching cell phones with their pants down, now.
