I've been watching a lot of the footage coming out of the conflict. The Israelis were using almost exclusively Mk-84 2000lb class warheads with various guidance kits attached (JDAM, Paveway, Spice). These are the largest class of com

First, very slight correction to the thread, most civilian craft have transponders, not IFF. They're kinda the same thing in practice but transponders just give out a static number, IFF is a cryptographic challenge response. I don&#x2

Why would you use AWS for that? That seems like an extremely strange external dependency for a house running on rainwater.

I daily drive graphene. It's very good and I haven't had any issues with it. I think the security/privacy claims are somewhat overstated but it's definitely better than stock and gives you a lot of freedom in terms of ho

Wouldn't this be a pretty obvious anti trust violation?

This is also the absolute worst nightmare of all the ragchew/gout-net types. The thing is [opens SDR waterfall] 70cm/2m is a wall of blue occasionally punctuated by a lonely repeater kerchunk so I'm not sure what's driv

Re common case, it's typically an accidental thing. Lots of people are standing up things like ham mesh networks and similar but anything internet proximal has a very high likelihood of leaking cypher text over the air. Re basic case,

You can still have an In-The-Clear ID requirement, ie frame packets as: AB0CDE--*UI93.8u[3u9,8husoa...

Cool, so a central component of a disaster response is preparation. How do you practice for that when you can't do real key enrollment/management outside of a real disaster?

There are power limitations on spread spectrum emissions in some of the bands, you could have the same thing here.

They're used on the ham bands all the time, you just don't notice.

by edrxty 3y ago
The secret is there's already tons of encrypted communications on the bands because of cheap chinese DMR radios that unlicensed teenagers use for airsoft and the like. It has yet to ruin ham radio and nobody has even noticed enough to

The most common case people run into: I want to be able to interface with literally any other communication technology in common use without having to strip TLS. The basic case: Alice wants to talk to Bob and would rather not have their cra

Seconded. You can still have a requirement to ID in the clear if you want, but all other modern radio systems are encrypted and any interesting protocols will be largely indistinguishable from encryption from a regulatory point of view. H

Precisely. It would be great if everyone had access to the same chat networks so we don't have to form cliques around what should be dumb hardware.

Not everyone wants an iPhone, there are lots of things you can't do on them because of apple's hyper militant approach to their app store. Things like: - Terminal emulators (iSH doesn't count, it's a terrible hack) - Tor

DMR/DStar is fairly popular where I am, though it's mainly through repeaters. Also, by far the most heavily trafficked frequency anywhere I've been is APRS which is digital store and forward messaging. It's just extreme

It's not really meant for the same applications as 802.15.4. it competes with DMR, DStar, and C4FM for narrow band digital voice over very long distances (single links can exceed 100mi easily). What it solves relative to its competito

Shrug? This is just 146.520 with extra steps, everyone will just use that instead. It's not like there's competition, that frequency gets more and more dead by the year. Digital is the present and future for amateur radio. M17,

Efficiently is a bit of a stretch. I worked at a company making consumer electronics that got bought by PE. They promptly drained all accounts and just ran the company on minimum possible funding such that they never got to make any capit
