jurov: there's a nutjob apocalyptic-prepper shortwave station, with 5-euro receivers widely available they seem to get some audience ☟︎
decimation: back in the day, ham radio folks used to run something much like fidonet except completely over shortwave/vhf radio
trinque: trilema and loper I expect to be able to get via hamsterwheel shortwave gossipd someday
decimation: gps, shortwave, longwave, etc
decimation: For something like shortwave broadcast, this is what you would want
ascii_field wonders if mircea_popescu is using 'clocks' thing to look for a nice voice to go on the #b-a shortwave propaganda station
decimation: but I'm not sure how many people in eastern eu countries had shortwave receivers
decimation: jurov: surely they received it on shortwave
decimation: my understanding is that latin jazz was inspired by shortwave broadcasts of us jazz
assbot: WWCR.com | Home - WWCR Shortwave, Nashville, Tennessee, USA ... ( http://bit.ly/1Crd8Td )
decimation: shortwave in the us is a desert of crazy
nubbins`: you pick up some bizarre things on shortwave sometimes
asciilifeform: how pastebin crept back in << rough substitute for the shortwave station we don't have
decimation: in theory it could be used on shortwave, if you had the hardware for it
decimation: if anyone is interested in simulation, usg publishes a free software package to simulate shortwave paths: http://www.voacap.com/prediction.html
mircea_popescu: anyway, it may be that the entanglement experiments come to fruition, and shortwave as well as the current telco version of internet become obsolete at the same time.
decimation: PeterL: a 'standard' shortwave channel is 4 kHz in width, through which you can push maybe a few kilobits/sec depending on what kind of scheme you are using
PeterL: how high of bandwidth could you transmit over shortwave?
decimation: the problem is that the 'image' of shortwave is AM broadcast, but nothing prevents advanced digital schemes
decimation: asciilifeform: "Germán Armando Plett’s knowledge was scraped together from the ‘Deutsche La Plata Zeitung’ (German La Plata Newspaper) and the nightly German radio broadcasts he was devoted to." << shortwave broadcast is dying, I guess because internet
asciilifeform: (nor an immediate transposability to shortwave/message-in-bottle)
asciilifeform: shortwave radio, castaway bottles, obelisks.
mircea_popescu: decimation: 16 kHz is probably the max that you will get allocated politically << by the time blockchain over shortwave, "politically" strictly means bitcoin-assets anyway.
decimation: AM on shortwave is ~12 kHz
decimation: I think what shortwave would be better for would be a transaction network
decimation: at any rate, I'm not sure that shortwave is really suited for blockchain broadcast unless one had a really big transmitter (and more importantly - government-allocated bandwidth)
Overand: shortwave could work.
decimation: most shortwave broadcasters limit their DRM to 14 kHz
Overand: decimation: Also, I'm a ham radio operator, I've had plenty of conversations via shortwave
decimation: Overand: shortwave is plenty reliable, depending on your expectations
Overand: Shortwave's fine, but it's subject to a ton of ionospheric stuff.
kakobrekla: for that you need shortwave, not optics.
asciilifeform: or when there's a gap in the usg shortwave jammers
asciilifeform: or shortwave.
decimation: most of the modems that are now in use on shortwave are designed to turn the natural broadcast medium into a point-to-point link
asciilifeform: at any rate, tiny packets plus fountain code plus each one is signed, will work great with transmission media other than internet (say, shortwave)
asciilifeform: parameters of raptorcode can be tweaked depending on noise floor values (e.g. shortwave in the apocalyptic wasteland requires more 'leg room' than comfortable modern net under ideal peacetime conditions)
asciilifeform: this is more of a shortwavecoin apocalypse gizmo.
asciilifeform: this also neatly dovetails into 'apocalyptic shortwave radio' net.
decimation: no - shortwave
decimation: asciilifeform: reminds me of the first Stierlitz episode where he receives the enciphered message on shortwave
decimation: bitcoin <is> shortwavecoin
asciilifeform: shortwavecoin awaits.
bounce: shortwave radio mailing lists? o_O?
asciilifeform: i confess that i rather like the mailing list idea. readily convertible to 'apocalyptic' shortwave radio...
asciilifeform: BingoBoingo: you were probably thinking of blockchain-over-shortwave ?
decimation: X-Rob, that's pretty neat to have a freepbx dev here. There needs to be some method to move some of this onto shortwave
decimation: asciilifeform: FYI you can listen to that Morse code vaccuum pendulum clock on the remote shortwave receiver I linked a few days ago.
decimation: asciilifeform re: clocks << http://ok0epb.nagano.cz/index.php?page=Main+page << Czech guy built a Froment clock, put in vaccuum chamber, transmits time using Morse code on shortwave
decimation: poor-man's substitute: single channel shortwave receivers available on-demand: http://www.globaltuners.com/receiver/ and http://websdr.ewi.utwente.nl:8901/
asciilifeform waits for shortwave-mpex
asciilifeform: orlov, if i recall, answers 'bitcoin' with 'the net dies in $nibble years and where's your shortwave, huh. count me out.' ☟︎
asciilifeform: we should have an open line << what's it cost / who one needs to kill / etc. to get a shortwave channel?
asciilifeform: works best with the (hypothetical) north korean blockchain shortwave repeater.
decimation: I prefer to keep the lower frequency EM fields around my house pure, so I can receive shortwave well
decimation: spam the shortwave spectrum for a few megabits
asciilifeform: ninjashogun: your second homework is to play ussr national anthem using a pc, c or cpp program, and a shortwave radio.
decimation: actually btc might work on shortwave
asciilifeform: btc over shortwave!
asciilifeform: pankkake: this is where the shortwave comes in.
asciilifeform: you should tell him about slavecoin-over-shortwave.
Diablo-D3: shortwave is probably too high bandwidth for what we want
Diablo-D3: so what, just bouncing it off shortwave using high gain antennas?
asciilifeform: mircea_popescu: without ionosphere bounce (shortwave, <30MHz) or something like MBC you will have a very short usable distance.
asciilifeform: mircea_popescu: possibly relevant to your future "Bitcoin over shortwave" station: http://www.dtic.mil/dtic/tr/fulltext/u2/a207831.pdf ☟︎
