sorry for being unclear, i forgor a word. what i meant that certain antenna designs would have specific fractional bandwidth, so that just scaling that design to higher frequency makes usable bandwidth wider in kHz terms. in order to get higher fractional bandwidth more complex or bulkier designs would be required, like thicker conductors, added parasitics, something LPDA-shaped, or maybe elaborate matching circuit, all of which cost money. i guess that while resonant amplifiers are a thing, probably bigger limitation would be bandwidth of mixer

i'd also note that antennas, amplifiers and so on have bandwidth that is some % of carrier frequency, depending on design, so just going up in frequency makes bandwidth bigger. getting higher % of bandwidth requires more sophisticated, more expensive, heavier designs. LoRa is much slower, caused by narrowed bandwidth but also because it's more noise-resistant

but there's separate category for "broadcast", so it's more of point-to-point thing?

what's fixed service in this context?

that key to heaven was probably something between mistranslation and bs, but there's so many more awful shit!

electric swamp - iraq used swamps as a natural barrier, laying mines, placing mortars and HMGs around, and also putting high voltage wires in water. when iranian raid was detected, they'd just fire a bit until iranians fell to water, then turned power on

BWR fights - phoenix missiles on iranian tomcats. iraqis had no idea what's going on to the point that they suspected sabotage (mirages just fell apart in air for no reason)

war profiteering - lots of countries sold covertly weapons to iraq or to both sides, but swiss were probably worst: they sold gas masks to iran and chemical weapons precursors to iraq

ww1 era warfare complete with said chemical weapons, and also genocide of Kurds for some reason

and all for nothing (result: status quo ante bellum)

Both got much more interesting. Also, don't underestimate modern encryption

cyanide doesn't accumulate, it can be broken down in some hours (very small amounts of course). otoh many heavy metals do behave this way, maybe you worked with both at the same time

all metals that bind to sulfur well are to some degree poisonous. these are lead, mercury, thallium, some platinides (in salt form), arsenic, and also copper, but less than others. some metals have other mechanisms of toxicity, like nickel, hexavalent chromium, cadmium, beryllium or barium. some of these accumulate in brain or bones, and some don't. some are more toxic when inhaled like zinc or chromium

it's absurdly easily detected and somewhat easily treated today, not in op's setting

when bubble pops, chatbots will vanish but nukes will remain for a long time

you also get points for historical accuracy, as it was used as far back as ancient rome

also, how low tech is low tech? Litvinenko was dying for three weeks after polonium poisoning, and radium will have similar effects, first extracted 1898
