Pay no attention to the man behind the curtain

Cheeky today are we? They’ll also write in all of Ukraine for them

at least he didn’t cause a civil war

more like task failed successfully

plenty of drone teams release geolocated videos day after they happen, but in this case i’ll guess that real sauce is classified top secret, that thing is outdated info and everyone is five steps ahead

ahem

triple the defense budget

the theoretical reason for doing that is that if you have to split jamming power over broader frequency range, then for every n^2 times increase in bandwidth, here number of channels, range decreases n times. however gnss signals are so weak, it probably doesn’t matter, and if you’re adding extra power per channel, then it doesn’t apply

now if missile detects that gnss is fucked with (signal too strong, wrong direction, physically impossible location), the correct thing to do would be to fallback to inertial navigation while accepting that accuracy decreases until gnss can be received again, if at all, and acted upon. theoretically speaking, it’s a matter of software update, better hardware also can help with that, so idk why would they release this. maybe there’s something that prevents this

These sound like some random plankton orgs, you can just as well pick a name and start your own

things that bounce from ionosphere. shortwave radio, AM broadcast, some military communications. couple of radiooperators will take a break for a day or two until space weather gets calm. unlikely that satellites would get fried

if you’re lucky, you might see aurora tomorrow, even if you’re in area that usually doesn’t have them (easier for southern hemisphere)

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

it’s lowkey crazy how fast has she adapted to being a conservative grifter

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
