| shauno | really. it's been running for 35 minutes now. 3GB of ram, still pegging a whole core, still no idea if it's even working | 02:06 |
| daftykins | are you sure it's not just what's owning freenode? ;) | 02:06 |
| diddledan | shauno: what you up to? | 02:07 |
| diddledan | or rather what do you hope you're up to? | 02:07 |
| daftykins | he's replacing James Earl Jones' voice with his in Star Wars | 02:08 |
| diddledan | I'm messing with C and C++ code right now | 02:10 |
| diddledan | not quite ready to reveal all yet tho | 02:10 |
| shauno | I honestly have no idea. all the examples I can find are 'load a wav in, mumble some jumbo about fft's, et voila, a graph". I can't find anything about stepping through it bit by bit yet | 02:13 |
| shauno | but I'm running one of the examples I found, and listening to my fan go up, and down, and up, and down | 02:13 |
| daftykins | dem fast fourier transforms | 02:14 |
| diddledan | much better than the slow ones | 02:14 |
| shauno | I've tried reading, but I still don't understand what they even do. | 02:14 |
| shauno | granted 2am's probably not the best time to find out | 02:15 |
| daftykins | i was under the impression they're mathematical functions that mp3 uses to represent the more complex wave form in audio, in a smaller storage size | 02:15 |
| shauno | I think I'm going to head to bed and leave it to it. I've checked it's running as x86_64, so I don't have to worry that it's getting awkwardly close to 4GB | 02:19 |
| daftykins | :> | 02:19 |
| daftykins | nn sir o/ | 02:19 |
| shauno | although last time I left something as "hah, I have all the ram in the world", i woke up to find it'd gnoe 400GB into swap and fallen over. oh well | 02:20 |

| davmor2 | bigcalm: play a game wait for the fan to kick in you know nvidia is being used | 12:36 |
| davmor2 | bigcalm: the intel chip has no fan :) | 12:36 |
| bigcalm | davmor2: I was getting the fan in use when playing minecraft | 12:37 |

| === ormiret_ is now known as ormiret | ||
| davmor2 | bigcalm: the other thing you can do is look at Nvidia-settings | 12:40 |

| davmor2 | bigcalm: you can also keep the settings app open and look at the temp of the card :) | 12:41 |
| bigcalm | I'm testing with Papo & Yo | 12:43 |
| bigcalm | Running smoothly | 12:43 |
| bigcalm | This is going to eat battery I bet | 12:43 |
| bigcalm | So when is this going to get back ported to 13.10 so I can use nvidia on my desktop again? :D | 12:44 |
| === aaronr_ is now known as aaronr | ||
| davmor2 | bigcalm: hell yes hence being able to drop to intel on a whim | 12:47 |
| bigcalm | As long as it's all automatic one doesn't have to specify with applications should be rendered via nvidia (this is what bumblebee did I think?) | 12:51 |
| davmor2 | bigcalm: yes it's like the cpu indicator modes for saving power on your cpu by switching to power saving mode you can get another 30+ minutes from the laptop as it only uses the cores it needs rather than available | 12:55 |
| bigcalm | The battery life in my new laptop is rather nice. Looking forward to bringing it to the LUG on Wednesday | 12:57 |

| bigcalm | Good luck :) | 13:21 |
| davmor2 | bigcalm: the other thing you might want to do that will help with the settings is sudo vim /etc/init/nvidia-persistenced.conf and add to the end of the exec line "--persistence-mode" minus the quotes | 13:32 |

| shauno | (out of curiousity, irc. nxdomain's here, but chat.f.n is fine) | 16:16 |
| nigelb | mapps: yeah, there was a DDoS against freenode. | 16:18 |
| cocoa117 | does online storage service like dropbox or google drive provide a way for me to check upload file's digsignure? e.g. md5 or sha1? | 16:18 |
| cocoa117 | i want to be sure my backup file uploaded to the cloud is indeed correct file, not the corrupted one | 16:19 |
| mapps | ahh really | 16:23 |
| mapps | ho silly | 16:23 |
| awilkins | cocoa117, Dropbox stores files keyed on SHA1 but I'm not sure you can access this information since some git exploited it to make Dropbox into a file-sharing site and they locked things down | 16:24 |
| awilkins | cocoa117, Since it uses the hashes to determine whether it got the file uploaded, and which chunks of it need resyncing, I think it's pretty reliable | 16:25 |
| awilkins | Best test is probably to sha1sum the file on another machine and see if it matches | 16:26 |
| cocoa117 | awilkins, enn, i am talking about over 132G file family photo, video, personal files. even the each file is split in 200MB in size, it's bit hard work to upload them and then download again to verify | 16:28 |
| cocoa117 | awilkins, even i am running on fibre | 16:29 |
| awilkins | cocoa117, Dropbox does P2P syncing | 16:29 |
| awilkins | cocoa117, So if you have two boxes on the same network it will use the local link - all the other box gets from the server is the file catalog | 16:29 |
| cocoa117 | awilkins, ohhh, i see what you mean by P2P syncing | 16:30 |
| cocoa117 | awilkins, i assume the file catalog from the server will contain digital sigure of the file i uploaded, and dropbox will check internally if file is corrupted? | 16:31 |

| shauno | verrry slowly | 18:33 |
| ali1234 | run it through a FFT with scipy? | 18:35 |

| ali1234 | daftykins: you would make about $2-4 per day after electricity costs | 19:20 |
| daftykins | ali1234: mmm, probably not too great then | 19:21 |
| daftykins | would you do it? :) | 19:21 |
| ali1234 | you're unlikely to make ROI | 19:21 |
| daftykins | yeah | 19:21 |
| ali1234 | i am doing it, but i already paid off my hardware costs | 19:21 |
| daftykins | seems too much of a gamble really | 19:22 |
| ali1234 | it only makes sense if you think the coin price will rise in the future | 19:22 |
| daftykins | well, a single R290 for £240 doesn't seem too big a deal? | 19:22 |
| ali1234 | and if you think that you;re better off just buying coins | 19:22 |
| ali1234 | well you're looking at 100 days to ROI | 19:22 |
| ali1234 | difficulty will be higher | 19:22 |
| daftykins | true | 19:22 |
| ali1234 | the question is, will the coin price increase too? | 19:23 |
| daftykins | yeah, perhaps my initial thought that it's too late to get into was correct | 19:23 |
| ali1234 | as i said, if yout hink it will, just buy some coins | 19:23 |
| ali1234 | there is more to it than that | 19:23 |
| ali1234 | currently you don't GPU mine bitcoins at all | 19:23 |
| ali1234 | it's not even at all profitable to do that if you pay for electricity | 19:24 |
| ali1234 | instead you would mine altcoins and sell them for bitcoins | 19:24 |
| ali1234 | now that is a really big gamble | 19:24 |
| ali1234 | because you never know if an altcoin will die after 1 day | 19:24 |
| daftykins | this guy in the other chan is on doge | 19:24 |
| ali1234 | if you are on the ball and you know a lot about the tech, you can pick the better ones and make a profit, but it's a lot of work | 19:24 |
| ali1234 | i mine on a pool that automatically picks the best coin and then sells it and pays out in bitcoin | 19:25 |
| ali1234 | so i don't have to worry about it, but this is less profitable than doing the work yourself, and the pool owner might be skimming | 19:25 |
| daftykins | ah-har | 19:25 |
| ali1234 | this is where the 2-4$ number comes from too | 19:26 |
| daftykins | and that's best-case? | 19:26 |
| ali1234 | if you pick the right altcoin and you mine it from the very second it launches, you can make $100 in 1 day, if you get lucky | 19:26 |
| ali1234 | but there's so many altcoins launching every day now, this cannot contnue | 19:26 |
| ali1234 | you have to watch the forum like crazy, get the source, check it for exploits, compie it, and get it mining on a fast network connection inside half an hour | 19:27 |
| ali1234 | if you don't have time for that (and who does) then $2-4 is best case, yes | 19:27 |
| ali1234 | on the other hand, it's always been this way | 19:29 |
| ali1234 | ever since the 2011 bubble, instantaneous mining profitability has never been over a couple dollars per day | 19:30 |
| ali1234 | not for more than a week at a time anyway | 19:30 |
| ali1234 | you shouldn't really take anyone's word for anything when it comes to bitcoin - and the beautiful thing about it is you don't have to | 19:31 |
| daftykins | heh | 19:32 |
| daftykins | i think given electricity is more expensive over here too, it's probably a waste of time | 19:32 |
| ali1234 | my numbers are based on 20p/kWh | 19:33 |
| daftykins | ah | 19:33 |
| ali1234 | the 290X might be more or less efficient than my 5870 though | 19:33 |
| ali1234 | i mean obviously it will have better hash rate, but it will use more power too | 19:34 |
| daftykins | yeah just looking up a review of how much power it pulls | 19:34 |
| daftykins | at idle its' 80W consumption would double my file servers draw XD | 19:34 |
| ali1234 | also tweaking it for max efficiency is something you'll need to spend a couple of weeks on | 19:34 |
| daftykins | looks to be about 400W load | 19:35 |
| ali1234 | that's about 4x what the 5870 uses, and it has about 4x the hash rate | 19:35 |
| daftykins | so that'd multiply my servers consumption by 6 | 19:35 |
| ali1234 | so pretty much what i expected | 19:35 |
| daftykins | what would you do if you were a beginner as i am, right now? :) | 19:37 |
| ali1234 | i dunno | 19:40 |
| ali1234 | there's no way i would have left it this long :P | 19:40 |
| DJones | daftykins: That sounds lile a "give £1000 to ali1234 and forget about it" | 19:40 |
| DJones | s/lile/like | 19:41 |
| daftykins | heh, yeah i never bothered looking into it though | 19:41 |
| ali1234 | i would consider whether you have any other use for a GPU | 19:43 |
| ali1234 | you may need a power supply upgrade too | 19:44 |
| daftykins | not especially, already got an older 560Ti in my desktop | 19:44 |
| daftykins | nope running pretty nice PSUs | 19:44 |
| daftykins | 750W Corsairs, gold i think | 19:44 |
| DJones | I was reading about one of the dedicated mining rigs thats just been released costing $6,000, said it was underpowered from advertised, late, manufacturer was offering free upgrades but would return investment in 3 weeks | 19:45 |
| daftykins | yeah i think i read about that | 19:45 |
| DJones | Plus used as much alectricity as a 2Kw fan heater | 19:45 |
| ali1234 | so 2Kw then? | 19:46 |
| daftykins | lol | 19:46 |
| DJones | ali1234: Let me find the link, think it was from el reg | 19:46 |
| ali1234 | the thing about mining ASICs is that you have to get in line if you want one | 19:46 |
| ali1234 | people who are receiving them now ordered them like a year ago | 19:47 |
| DJones | That sounds like what I'd read | 19:47 |
| ali1234 | buy now, and by the time you get it, difficulty will be so high that you'll never make ROI | 19:47 |
| ali1234 | also half the companies never deliver at all and just go bust/steal your money | 19:47 |
| DJones | This is the one http://www.theregister.co.uk/2014/02/03/cointerra_ships_bitcoin_miners/ | 19:48 |
| ali1234 | i would not buy an ASIC at this time, except maybe a block eruptor just for lolz | 19:48 |
| ali1234 | order now and you'll be in the "May" batch | 19:52 |
| DJones | ali1234: Is there much point now even buying a good graphics card and starting mining, or to use the expession, has the horse bolted | 19:52 |
| ali1234 | see above | 19:52 |
| ali1234 | it is largely a gamble | 19:53 |
| * DJones reads scrollback and sees the answer not really | 19:53 | |
| ali1234 | if you buy the GPU at least you have a GPU | 19:53 |
| ali1234 | if you just buy the coins you can end up with nothing | 19:53 |
| daftykins | DJones: i'm thinking it's probably not wise - but then for only £250, you can always sell the card later | 19:58 |
| DJones | daftykins: Yeah, for me, I'd need motherboard, memory, processor etc, all the desktops I've got here are at least 8 years old, AGP 4X at best for graphics | 19:59 |
| daftykins | >_< | 20:00 |

| shauno | okay, I'll admit I'm stumped. 120 lines per minute is 2 lines per second. 11025 samples per second is 5512 samples per line. the only way I can make 1800 pixels wide is 3 samples per pixel, and it doesn't seem to be possible to derive a frequency from 3 samples | 20:20 |
| MartijnVdS | shauno: why not? | 20:23 |
| shauno | I have no idea, but I get divide by zero and 'NaN' if I go below 40 | 20:24 |
| shauno | and some of these are pages of text up to 94 characters wide; 138 pixels per line ain't gonna work | 20:27 |
| ali1234 | you have to subsample it... | 20:28 |
| ali1234 | also you have to oversample the original signal | 20:28 |
| foobarry | can i unlock a phone which is locked to tesco mobile> | 20:29 |
| foobarry | ? | 20:29 |
| shauno | I'm suspecting throwing fft's in bins isn't the right way to do this | 20:30 |
| ali1234 | what do you have for a raw signal? | 20:30 |
| shauno | at the moment, 60 seconds recorded off the radio, WAVE audio, Microsoft PCM, 8 bit, mono 11025 Hz | 20:32 |
| ali1234 | well 11025 Hz isn't going to cut it if that is the FM modulated signal | 20:32 |
| MartijnVdS | yay nyquist | 20:33 |
| ali1234 | is that IQ or is it already demodulated? | 20:33 |
| shauno | demodulated | 20:34 |
| ali1234 | but it's still just two tones, effectively? | 20:34 |
| shauno | right | 20:36 |
| ali1234 | can you upload it? | 20:36 |
| shauno | http://lab.oneil.me.uk/hffax/test.wav (and .py is my ugly work so far) | 20:38 |
| ali1234 | is it signed or unsigned? | 20:41 |
| shauno | was actually just looking at that, the arrays don't need to be floats anymore | 20:42 |

| dwatkins | foobarry: what's the max output from the desire's charger? | 20:57 |
| dwatkins | "Any Motorola charger with the correct micro-USB tip will charge your Moto G. You will see the best results when the output of the charger is between 500 mA and 1.5 A" | 20:58 |
| foobarry | output 5V=1A | 20:58 |
| foobarry | \o/ | 20:59 |
| foobarry | i think we're good | 20:59 |
| foobarry | thanks dwatkins | 20:59 |
| dwatkins | no worries | 21:00 |
| foobarry | checked my touchpad charger and its 2A :-o | 21:00 |
| dwatkins | yeah, I think my iPad ones are the same rating, handy for quickly charging a phone, too | 21:00 |
| MartijnVdS | only if the phone supports it | 21:00 |
| MartijnVdS | good thing devices don't pull more amps than they support, even if the charger supports (a lot) more | 21:01 |
| foobarry | so the touchpad one is variable i assume | 21:01 |
| foobarry | electricity is confusing | 21:01 |
| MartijnVdS | foobarry: they are all variable.. the rating on the thing is the maximum | 21:01 |

| MartijnVdS | yay EU :) | 21:02 |

| ali1234 | shauno: i don't understand why it's so wiggly | 21:13 |
| shauno | the audio? I'm working on trying to capture a better sample this evening | 21:16 |
| diddledan | wiggly? you should see his shelving that he DIY'd | 21:17 |
| ali1234 | i'm playing with fldigi at the moment. trying to understand what the data format is really like | 21:17 |
| shauno | ah, yeah in which case that's a particularly bad sample. it's literally just 60 seconds shaved off the end of my last capture, because some of the examples I was playing with last night took hours to run against a 25-minute capture | 21:18 |
| ali1234 | it shouldn't wiggle though! | 21:18 |
| shauno | right. half a second should be half a second anywhere | 21:19 |
| ali1234 | the wiggle always seems to be 1-2 px per line | 21:20 |
| ali1234 | are there any "good" example recordings online or something? | 21:22 |
| shauno | http://www.rtl-sdr.com/wp-content/uploads/2013/04/WeatherFaxAudio.ogg is pretty clean (but inverted) | 21:25 |
| ali1234 | fldigi can't open that | 21:26 |
| * diddledan watching ch5 - the great british benefits row (live) | 21:27 | |
| shauno | ah I have my audio looped back, so fldigi thinks everything's live off the air | 21:27 |
| ali1234 | yeah i want to eliminate any possible hardware errors | 21:28 |
| ali1234 | for reference, how do i loop it back? | 21:28 |
| ali1234 | pulseaudio? | 21:28 |
| shauno | no idea, I'm on osx (And I'm just using a cable plugged into both ports :) | 21:30 |
| shauno | since the mac has line-level input instead of mic-level, it works pretty well (for this, and nothing else) | 21:30 |
| shauno | I can't actually find where I'd open a recording in fldigi. fun | 21:32 |
| ali1234 | file->audio->playback | 21:32 |
| shauno | ahhhh. having a tick-box on it misled me there | 21:33 |
| ali1234 | apparently my microphone is near enough to the speakers to pick up the sound | 21:35 |
| ali1234 | that ogg file is nowhere near a full picture though | 21:35 |
| shauno | this looks pretty good; http://www.svfreya.ca/wefax/48HrWindWave_Valid201302011200.wav | 21:35 |
| shauno | 13meg or so, but it's a complete tranmission | 21:35 |
| shauno | including all the phasing pre-amble, which is visible/decoded if you tick 'non-stop' in the wefax options | 21:36 |
| ali1234 | so do you get a "straight" image with non-stop mode? | 21:36 |
| ali1234 | or is it wavy? | 21:37 |
| shauno | it's about the same | 21:37 |
| shauno | it's only really interesting because that way I can see the 'header' which is meant to define the timing | 21:37 |
| shauno | otherwise fldigi tries to snip it to the beginning/end of the actual image | 21:38 |
| ali1234 | this signal is much stronger | 21:39 |
| shauno | everything's bigger in 'murka :) | 21:40 |
| shauno | it's still skewing quite heavily for me though. even though I note they have a solid edge to key off | 21:41 |
| shauno | rather than the black/white board the european stations use. a solid edge would make things much easier later on | 21:42 |
| ali1234 | well, i opened the wav file in playback mode, and it doesn't skew | 21:42 |
| ali1234 | even in non-stop mode, there is a small bit of skew, but it is constant | 21:43 |
| ali1234 | which is what i'd expect | 21:43 |
| shauno | mine's skewing but it's fairly constant | 21:43 |
| ali1234 | it's absolutely constant here | 21:43 |
| shauno | eg, the straight lines are straight, they're just not the right straight | 21:43 |
| shauno | but such that I could fix it in the gimp in 2 seconds, rather than .. what I"ve been receiving | 21:44 |
| === alan__ is now known as AlanBell | ||
| ali1234 | sample recording "sounds" very different to yours | 21:47 |
| shauno | it sounds much stronger. other than that it just sounds like it has a much more pronounced 'tick' because of that heavy black bar | 21:49 |
| ali1234 | ooo... i just found a meteosat signal on that websdr thingy | 22:33 |
| ali1234 | and... it's all wavy | 22:33 |
| ali1234 | shauno: northwood meteosat? | 22:34 |
| shauno | yup, same | 22:34 |
| ali1234 | s/sat/fax/ | 22:34 |
| shauno | should be 4610 and 8040? | 22:35 |
| ali1234 | yeah 4610 is where i am at | 22:35 |
| shauno | well, sorta; apparently you're meant to tune 1.9 below the published frequency | 22:35 |
| ali1234 | i'm actually at 4608.58 | 22:36 |
| shauno | they're the same ones I've been playing with; 4610 & 8040 is GYA (northwood) and 3855, 7780 & 13882 are DDK (pinneberg DE) | 22:37 |
| shauno | there's not much between them here, because the german ones run twice the power (20 vs 10kW) | 22:38 |
| shauno | ymmv, of course, since the websdr is in holland? so germans with twice the power might be just the ticket | 22:39 |
| ali1234 | how often do they start up? | 22:39 |
| shauno | I'm not entirely sure; I have a schedule, but they give the impression they haven't seen it | 22:40 |
| shauno | there's rarely 10 minutes gap between pages during the day, but they're a lot less frequent overnight | 22:41 |
| diddledan | pages? | 22:42 |
| diddledan | I still have no idea what you're actually doing | 22:42 |
| shauno | if it makes you feel any better, neither do I | 22:44 |
| shauno | I don't actually have an end-goal here, I'm mostly just annoyed that fldigi can't keep these in sync, and curious to see how it could be done better | 22:45 |
| ali1234 | i would just fix it after turning it into an image | 22:46 |
| shauno | that was my original plan, before someone told me it'd be easier to stuff the original data into scipy ;) | 22:48 |
| ali1234 | by original data i meant the demodulated black and white pixels | 22:49 |
| ali1234 | so, after you turn it into an image, but before you turn it into a png :) | 22:49 |
| ali1234 | but fldigi doesn't seem to be able to give you that | 22:50 |
| shauno | well, I'm gonna stick with it for now; I must be learning something, because my head hurts | 22:53 |
| diddledan | shauno: sometimes that happens when you bash it against a brick wall repeatedly | 22:55 |
| ali1234 | hmm there... i've got it going directly from the pulse monitor source now | 22:55 |
| ali1234 | so i don't have to listen to the crazy squeeks | 22:55 |
| shauno | hah, I prefer the crazy squeaks. I prefer my ears over the waterfall | 22:57 |
| diddledan | I'm not sure inlaws are appropriately described as crazy squeaks | 22:57 |
| ali1234 | both useful, but not when you're just waiting for them to start up the transmission again | 22:57 |
| ali1234 | also it should give a cleaner signal that the old analogue hole method | 22:58 |
| shauno | yeah, I had problems with the washing machine that way, which is why I found a cable | 23:00 |

| ali1234 | right, i'm getting a clean signal through PA null sink, but it's still all wavy | 23:34 |
| shauno | perhaps northwood just need some wd40 | 23:38 |
| ali1234 | maybe. this schedule looks actually accurate: http://www.nws.noaa.gov/om/marine/rfax.pdf | 23:42 |
| ali1234 | http://imagebin.org/290840 is what i just got | 23:45 |
| shauno | yeah, that looks familiar | 23:45 |
| shauno | it's weird that it doesn't even wrap cleanly; the whole point of the black band at the top is that it should be centered | 23:46 |
| ali1234 | it does try | 23:46 |
| ali1234 | it jumps around during receiving | 23:46 |
| shauno | that's what I don't get - it shouldn't | 23:47 |
| ali1234 | i keep missing the start tho | 23:47 |
| ali1234 | hmm another one is coming in | 23:47 |
| ali1234 | i got the start, but this one is much more wavey than the last one | 23:47 |
| ali1234 | and the signal just generally looks worse quality | 23:47 |
| shauno | there's not much there to miss. there's a buzz that's meant to key timing, the black bar to center, and then the horrid scratchy noises | 23:48 |
| ali1234 | well i was looking around at other freqs :) | 23:48 |
| shauno | and then the sweeping tones mark the end | 23:48 |
| ali1234 | if you miss the start of the tx, you have to click "skip phase" etc | 23:48 |
| shauno | the bit that looks like a grayscale bar I guess | 23:49 |
| ali1234 | hmm yeah that makes sense, the half-second rising tone | 23:49 |
| shauno | Iwonder if there's any chance in hell of me waking up at 7am to find otu if murmansk is reachable | 23:49 |
| ali1234 | the one that is coming through now actually has ghosting on it | 23:50 |
| shauno | northwood again? | 23:52 |
| ali1234 | yes | 23:52 |
| ali1234 | i'm not seeing anything from the others | 23:52 |
| diddledan__ | what are you using to receive the signal? | 23:52 |
| ali1234 | and actually i'm only seeing anything from 4608 and not any of the other northwood freqs | 23:52 |
| ali1234 | diddledan__: http://websdr.ewi.utwente.nl:8901/ | 23:53 |
| shauno | if that schedule is right, it seems germany go quiet between 10pm till 0430 | 23:53 |
| diddledan__ | hmm, I'd be wary of that - there's probably no timing synchronisation | 23:54 |
| shauno | but if you can see rtty at about 4580, you can receive pinneberg | 23:54 |
| diddledan__ | hence the wavyness | 23:54 |
| ali1234 | shauno: is using a real radio tho (i assume) | 23:54 |
| ali1234 | and has identical wavyness | 23:54 |
| shauno | I'm using an rtl-sdr through a weird little hf upconverter I found on ebay | 23:54 |
| shauno | it's not great, but I get similar results | 23:54 |
| ali1234 | hmm | 23:55 |
| shauno | (And about 5 meters of speaker cable lol) | 23:55 |
| ali1234 | i can see that rtty stuff... signal is pretty good | 23:55 |
| ali1234 | no idea how to receive tho | 23:55 |
| ali1234 | hmm does fldigi autosave incoming tx? | 23:56 |
| shauno | fldigi should have it for rtty, but you'll have to customize the settings for it; something like http://cl.ly/image/3p0q2d1V0m0m | 23:56 |
| ali1234 | looks like it does | 23:56 |
| shauno | I have mine autosaving images, but I can't remember if that was my idea or not lol | 23:57 |
| ali1234 | what would i even see on rtty? plain text? | 23:57 |
| shauno | yeah | 23:57 |
| ali1234 | but, like, human language? or weird computer data? | 23:57 |
| shauno | radio-tty; just what it sounds like | 23:57 |
| shauno | http://youtube.com/watch?v=qUSbOgcmtco | 23:57 |
| ali1234 | i see | 23:58 |
| shauno | especially for maritime weather, there seems to be a lot of systems in daily use that you'd have assumed died 50 years ago | 23:59 |
