here if you need anything over certain power (6kW; depends on country i guess) you need a three phase installation, and even if you get single phase, it’s really handled as three phase split between single phase customers (a block gets three phase supply, then splits flats in three groups, each group gets connected to one phase). this gets supplied by a distribution transformer that might serve somewhere around 200 people per (in residential areas)

i understand that sometimes americans also get distribution like this, with 208/120 three phase coming from substation, without 240v available

american version would probably only have two phases at best, and possibly just one

wait, how do you route cables in there? is there just a massive bundle right through the middle?

ye except that depending on how paranoid are you this also means that all personal/small instances will be always suspicious and most of popular instances allow lots of that by default

Absolutely none, and it’s by design. All you need to do is setup an instance and everything you might need gets right into database

if you have an antenna with impedance of, say, 200 ohms, then you need to match it to transmitter impedance of 50 ohms, or else most of power output from transmitter would be bounced back and will damage output stage of amplifier. because on receive currents are tiny, you can wing it by just using it without any match and connecting it directly

transformers are not the only way to do this, and some other circuits can be used instead. if you take a transformer with 1:2 winding ratio, then if on one side current is 1 and voltage is 1, then on the other current will be 0.5 and voltage 2, which means that impedance increases 4x. in EFHW, it’s 1:7 winding ratio and impedance ratio is 49x, which works for end-feeding a half-wave dipole, just as expected (from 50 ohm to ~2500 ohm). that transformer is a limitation on power usable in this antenna and main reason to use this type of antenna is mechanical

most importantly, transformers work nicely only if you have real impedances, so your antenna has to be resonant anyway. l- or pi-network tuner will also handle complex impedances so doublet or random wire will work nicely with it, as long as you can accept weight and losses in tuner

how compact and what do you want to do with it? if it’s for receive only, the most compact you can get is ferrite rod antenna, but it’s very different from usual wire antennas used for transmission. if using wire antennas, random wire would be fine

it depends on whether you want to transmit or not. if not, you can just use random wire antenna

random wire antenna is exactly what it says on the tin - length of random wire strung up as high as you can, as long as you can make it work. the other part is ground, where you might want to lay some lengths of wire and connect them in a single point, to act as radio ground. it won’t have right impedance (probably 50 ohm) but for receive, this is ok - it’ll be probably usable, and you can amplify signal without penalty because amplifier noise will be much smaller than atmospheric noise already present. the amount of power bouncing around is tiny and can’t damage anything

if you want to transmit, you’ll need more elaborate antenna. what you can use depends on whether do you have a tuner like neidu3 describes or not. if you do, common choice is doublet which is a specific length of wire connected to tuner with a 400-ohm parallel line. if you don’t, common choice is halfwave dipole which is halfwave long, and put as high as you can get, either vertical or horizontal, but for practical reasons mostly horizontal, or monopole, that is quarterwave long, but requires lots of wire on ground to act as radio ground. you can make them shorter using coils, but this makes bandwidth narrower. in any case, it’ll be need to be tuned to your band in question, for which you need a tool like nanoVNA. tuner also narrows your bandwidth, but you can retune it so it doesn’t matter that much. (it’c called instantaneous bandwidth)

is there something you don’t understand? it doesn’t fucking matter what russians claim to have tested, you as nato resident are protected by nato’s ability to evaporate moscow and moscow residents survival instinct, meaning that they won’t start shit if they want to remain not evaporated. it works in any number of ways between any number of nuclear states, and can’t be undone

nothing. safety of people in nato is guaranteed by a several of icbms somewhere in wyoming or in some submarine with putin’s name on them. self-preservation is a mighty powerful instinct, and it worked for entire cold war. will easily work for a couple of decades more

the same way they did in 2021

I don’t want to be remembered at all. If I’m being remembered it means I’m dead.

ah yes chatbot seller says these things will become so capable, they’re gonna destroy the world, just you wait and see, but need trillion dollars in financing first. op have you eaten your daily recommended pebble today?

can these things be reflashed?

aluminum bars, they won’t be able to work it into things like with iron. even if they do, they can’t make more

New-ish EU national IDs have NFC capability and certificate in them so you can probably sign something with that if you figure out how

in any case it’s a safe bet to say he’s far right because something like 90% of american terrorism cases are far right

be aware that radio transmissions like this are likely to be recorded no matter if these are encrypted or not (also goes for other parts of radio spectrum)

maybe his neck just did that
