I see one of the founders (Ulrich Rhode) of Rhode and Schwarz on amateur radio some times, and I always ask for test equipment and he always says no.

That's very cool, he's basically test equipment royalty. But he's the son of one of the founders - Rhode & Schwarz was founded in the 1930's.

It’s good natured ribbing usually exchanged over QSL cards. I didn’t know he was the son! Ulrich never misses a QSL card for me. Cool dude!

I'd be curious if anyone finds it worthwhile to have a smartphone while being so paranoid that you have to hide it in a Faraday bag. I understand the problem. I just don't understand the practical use case: every time you use the phone, you have to take it out of the Faraday bag, and it can be used to spy on you or report information about you. Assuming you're keeping it in the Faraday bag all day, when and why would…

You would take out your phone if you would like to make a phone call, or check to see if you have received any messages. For the other 99% of your day, the IoT sensors being stuck on every conceivable object are unable to report back to HQ (and every agency and broker affiliated) your current whereabouts and trajectory.

So why not get a more basic phone and not a smart phone?

I once tried to acquire a RS PR100 like the one used in the test here. Turns out they cost more than a fancy car!

I wonder how much more capable they are than the cheap crap I can afford.

Bit of an aside but the ineffectiveness of tin foil hats to prevent government intrusion into our minds has been known for some time :) http://web.archive.org/web/20100708230258/http://people.csai...

I've lately started seeing claims on some of the forums that embrace things like vaccines contain 5G mind control chips claiming that lead effectively blocks government mind control and that is the real reason lead paint was banned, and that it is not actually harmful.

Oh for the love of god

I really like Snowden's recommended Faraday cage for phones or other devices of similar size: two drink-shaker cups[1]. Drink shakers are cheap and widely available. The average hotel room in any medium/large hotel chain probably includes a shaker as a standard item as part of the minibar. The simple two-cup style (as seen in [1]) is preferred over the fancier "strainer top" style because you can press the two cups t…

> The average hotel room in any medium/large hotel chain probably includes a shaker as a standard item as part of the minibar I've stayed in dozens of hotels all over the world, and never once have I seen a cocktail shaker in the minibar?!

I've stayed in over a hundred, frequently in suites (upgrades), often at 4* hotels, in 22 countries (Full set of brands - Marriot, Hyatt, JW, etc...) Ice Buckets are pretty common - but I have never once seen a drink shaker in a room mini-bar.

This is a super cool blog post. However I think it alludes to a much larger problem. For many products today, it’s very difficult or impossible for most people to verify the product works. For a network switch, there are free and open source tools like iPerf to test and verify speeds are as advertised. For a faraday box, you have to go through all these steps (and knowledge learned) just to be able to test these. Wha…

> What about for vitamins, or pet food, or any other “durable” products that are supposed to last for X years?

We could, as a society, make rules that prohibit these things and create organizations with the expertise and power to enforce those rules. We are hardly helpless, but the political trend is to forgo and even decry that power, do nothing, and then whine about how helpless we are.

Linus Tech Tips is attempting something in this field: https://www.youtube.com/watch?v=pt3-6BsWlPk tl;dw They're building a setup where they can test a bunch of computer equipment with standardised tests (built by them) in a standardised environment (also built by themselves).

Sounds like what Consumer Reports does across various fields.

What is the use case for disabling wireless communication for your phone? How will you use it? How will anyone call you? If you don't want to use wireless functions, buy a tablet that lacks all the radio hardware.

Bad Guys can't follow you using the signal. That's about it. Sure, they can tail you, but that's Work. And they'll know where you are the moment you take it out, but hopefully they're too far away to act on it.

All in all, if you NEED something like this, your opec had better include more than this.

A lot! An Ettus USRP + GNURadio could get you part of the way, but you then you don't get the nice handheld form factor and ruggedized chassis.
