Martin, he show us new revolution. But audience not understand it, so I translate in good English: SDR stand for Software Defined Radio.
Say you got an AT&T phone and can’t get your call thru ‘cause there is no tower near you. But the guy sitting next to you babbles away it seems like forever on his phone. He’s got Verizon or something—no problem for him. Makes you want to clobber him! Am I right?
Here is problem: All our gizmos these days work on hardware and everybody got different hardware. So Martin solves problem with software. The software translates one to the other. If they put Martin’s hoozitz in the nearest cell tower, both phones work on either network! It handles every frequency from 400 Megahoozits to 5 Gigahowitzers. 
I watch him set up his technostuff and show us. A member of audience makes call on AT&T phone. Martin catches it and sends it to other phone in room—Verizon phone. It rings. We see whole hookup happen on screen! Imagine you put it in every cell tower. Quality makes great leap! Cost drops to basement!
He says defense department try to develop this and cannot do it. Then private industry makes one, but it turns out way too expensive. Martin, his cost is only 1,000 bucks—hand-made! Maybe $200 mass produce.
How so cheap? Can you believe that inside your worn-out laptop computer is Intel chip or AMD chip—either one—and both got the guts to do this job? He uses teeny-weeny circuit board, 100 dollar laptop, and USB thingamajig. That is it!

So I pull Galaxy out of pocket and look this up. I find Forbes article that shows SDR used by hackers. It makes me wonder if I understand what I just heard. But the technology is real. Is scary. They hurt you and you cannot shoot them. I give you link to article.
You think I make this stuff up? I see it happen! Come to my place and we talk summore. Ludditis Shots ‘n Beer. We got potato pancakes better than Lithuania. I not even charge for sixth beer. Sveikes!
