Could be. Amplifiers are a bit more complicated and there are many things that can limit bandwidth

but you see, in case of accident they can just dump reactor core into seawater which will provide ample cooling and shielding. no biggie, just put multi thousand ton object that requires a village of engineers to work out on high seas

there are normal nuclear powerplants that use seawater as coolant and they’re all on shore. these require a lot of corrosion resistant heat exchangers along the way. there is one power barge like this, it provides power to russian far east, whole 70MW of it, costed 414 million dollars and needs 300 people onsite. your guess is as good as mine how many of them are military. 70MW, aka two or three aeroderivative gas turbines

If we consider groundplane antenna, which should be much better than anything that you can fit on a HT, it might be centered on 145MHz (region 2 band) and it’ll be good for 10MHz for 1:1.5 SWR (140-150) and 17MHz for 1:2 SWR (136.5-153.5) according to some random measurement, first that i found. Outside of these ranges SWR rises rapidly and if you tried to transmit on say 170MHz you might get SWR 1:5, perhaps 1:10 or worse if you’re unlucky. On receive this doesn’t matter too much because these nano- to microwatts of rx power would just bounce back harmlessly with the only effect being that apparent signal strength is lower. But if you tried to transmit then design currents or voltages would be exceeded and something will break, usually final stage of amplifier. This gets rarer than it used to be because some radios can measure SWR and will reduce power in such scenario. This also gets worse the higher transmitted power is

This happens because unlike on HF + 6m, on 2m and up ATUs are not a thing* and all antennas are expected to be matched. So you can use the same radio on GMRS or PMR or what have you and on 2m or 70cm band, but you have to change antennas between these uses. If you want to use all of these on one antenna, then there are special wideband designs like LPDA but this makes sense on a mast and not on handheld radio

* there are tuner designs that work on 2m and up, but you won’t find them in HT, there’s no point, they’re too big, too heavy and too expensive

Even if you tried and made it to work, there might be other incredible problems with things like harmonics or other spurious emissions because filters were not designed to work way out of these frequencies. For example you can try to force Quansheng UV-5K (?) to transmit on 60-ish MHz but most of the power goes out at 2nd and 3rd harmonic, because of the way filters were set up. Narrowband designs are much easier and this is what you’ll see all the time in amateur radio. Wideband and ultrawideband designs are constant source of job security for RF/microwave engineers

You can think of matching units and antennas (and to some degree even feedlines) as filters to some degree, because their bandwidth is not infinite

Note that there’s 25% of fractional bandwidth in there and many antennas won’t work everywhere in that range (and also other elements like power dividers, diplexers etc if part of circuit)

if it’s that thick, i expect it’s some kind of pharmaceutical dissolved in oil. over time oil, like sesame oil, will gum up and darken like this

hexbear userbase are tankies/campists with extreme brigading habit, this is why many instances are defederated from them. including this one

mods of a comm that has “fuck tankies” in tagline have a vote and agree to remove a tankie mod. there are receipts and entire post prepared in advance

at the same time said mod is removed as admin of a couple of matrix rooms. said mod is also db0 admin and seems to like leftist unity as long as it’s done her way only. three hours later she wakes up and her next move is to grab another, completely unrelated community and to move instances from blahaj to db0, a community where she was inactive as a mod for months, specifically so that it would be exposed to hexbear. we all know it works very well. it seems like this move was talked about with db0 admins but not other mods of said community.

this doesn’t go as intended, blahaj admin steps in and removes that mod from there too. the new community on db0 is also removed, which is something that can be only done by admin, presumably some other db0 admin. then said mod makes second big post, calls blahaj admin a reactionary, steps down as a db0 admin (“voluntarily”, somehow i doubt that), moves shop to hexbear (?)

It’s lowkey expected considering how hard it draws from self-help movements

related phenomenon. at calm solar surface, there’s only hydrogen and helium. these are excited thermally and can emit radiation, but the highest energy photon they can emit is ca 13eV and 52eV respectively. this is vacuum UV, and this is what is responsible for ionisation of ionosphere even during solar minimum, mostly F layer. but when solar flare forms, there are these giant loops of charged particles, and when charged particles change direction or brake, they release a lot of high energy radiation, that is xrays. xrays just go everywhere and this is partially what is responsible for extra ionisation of ionosphere during solar maximum, and this contributes more to E layer ionisation. (because xrays can go further through air) when solar flare hits the earth, protons from it cause extra ionisation in D layer and this is why post-flare blackouts happen

this is also why one metric of solar activity is solar xray flux

there are also solar xrays, which also ionize ionosphere and are associated with CMEs (regular processes on surface of sun cannot make much xrays, it’s only when high energy particles are smashed back at the surface xrays are emitted. intense magnetic fields are needed for that)

Fair. I’m doing synthetic chemistry for a living, and probably i have as much use of electrochemistry or crystallography as you do have of organic chemistry. I get it is a skill with a limited utility, and i might be biased, but i don’t get why people complain about it so much. On the other hand, one of my labmates was hired by mat sci lab as a single person fire brigade to unfuck their project, ant it worked despite no organic chemistry involvement

if you don’t mind, what field are you in that you were examined in ochem but you don’t use ochem? last time i’ve checked, chatbots crap the bed constantly when asked about anything that you can deduce (easily, by analogy) but can’t find, especially as text, the mistakes were either glaring or sneaky but never correct. it’s much easier to express what you mean by drawings in ochem anyway

they had big corporate contracts for their other, boring and profitable part of the business, but that won’t save them from openai going broke. it’s like 50x less than they need

i have been informed that the faster the company explodes the faster they can iterate, so eventually they’ll make company that doesn’t explode

pringles can is too small, you need a can 8cm in diameter minimum. 400ml cans won’t do but bigger ones, 800ml, 1200ml will work https://www.wikarekare.org/Antenna/WaveguideCan.html
