[05:31] <eroomde> great tracking from around there
[05:31] <eroomde> chanctonbury ring etc

[05:32] <Geoff-G8DHE-M> Used to be a nice walk up there and back on a good day.
[05:33] <Geoff-G8DHE-M> Even the ring is looking a little better, but not sure it will survive in the long term.
[05:33] <eroomde> too much foot fall?
[05:34] <Geoff-G8DHE-M> No a lot of trees died back about 20-30 years ago, which destroyed the shape, but they have tried to grow some other back
[05:35] <Geoff-G8DHE-M> which is working but not sure that they will ever have the "shape" that was so outstanding!
[05:35] <eroomde> never saw it in it's prime
[05:35] <eroomde> (am 25)
[05:35] <eroomde> er no wait, 26
[05:36] <Geoff-G8DHE-M> I think that was about when it died back, I was that age at the time! hit 60 this year!

[09:22] <Willdude123> Hi
[09:25] <Chetic> a 200bar 10 litre helium tank isn't enough to get to 30km, is it?
[09:25] <Chetic> without losing the damn thing I mean
[09:25] <gonzo_> http://www.batc.tv/streams/ukhas
[09:25] <gonzo_> a more readable url
[09:25] <SpeedEvil> What's the volume?
[09:25] <Chetic> 10 litres?
[09:26] <SpeedEvil> Chetic: the volume at stp
[09:26] <Chetic> 10*200 I suppose
[09:26] noname (541f040f@gateway/web/freenode/ip. left irc: Ping timeout: 250 seconds
[09:26] <SpeedEvil> yes, it's plenty
[09:27] <SpeedEvil> http://ukhas.org.uk/guides:balloon_data
[09:27] <Chetic> what will the weight constraints be on the whole thing?
[09:27] <Chetic> I don't know what my payload weight will be yet..
[09:27] <SpeedEvil> For example, with a 1kg balloon, and the full 2m^3, you can easily get 250g going up at 5m/s
[09:28] <Chetic> is that a good climb speed to aim for?
[09:28] <SpeedEvil> It depends if you want it back.
[09:28] <Chetic> haha I do
[09:28] <SpeedEvil> if you launch much below that, then it takes a long time to ascend and burst.
[09:29] <SpeedEvil> And may in some cases - if the rate is too small - not burst, but float for several days
[09:29] <Chetic> I really want to minimize the risk
[09:29] <Chetic> since I can basically only afford a single attempt before winter comes
[09:29] <tweetBot> @G0TDJ: James Coxon telling us how it used to be #ukhas http://t.co/PIwCR1YBH1
[09:29] <SpeedEvil> then sticking with 5m/s is probably a sane plan.
[09:29] <Chetic> but faster IS safer, right?
[09:29] <SpeedEvil> yes
[09:29] <Chetic> I'll just get a lower final altitude?
[09:30] <SpeedEvil> somewhat.
[09:30] <Chetic> ok good good
[09:30] <SpeedEvil> The above table is a reasonable guess

[09:42] <Chetic> I really need to weigh my payload
[09:42] <SpeedEvil> Looking along the table - with 1.2m^3 of helium, and a 500g balloon, with a 250g payload it'll get to 28km
[09:42] <SpeedEvil> A 250g payload is heavier than a mobile phone, but not heavier than two.
[09:42] <SpeedEvil> (typically)

[11:12] <DL1SGP> Greetings Graeme
[11:14] <Laurenceb_> A point on spectral efficiency
[11:14] <Laurenceb_> dominoex and MFSK lowers spectral efficiency
[11:14] <Laurenceb_> and gives quite a few dB gain, about 4 or so as a result
[11:14] <Laurenceb_> and very simply
[11:15] <SpeedEvil> Assuming that you are comparing it with a spectrally shaped FSK
[11:16] <SpeedEvil> A clean mfsk may use spectrum more efficiently because it's not got spurs
[11:16] <Laurenceb_> oh lol
[11:16] <Laurenceb_> next slide
[11:16] <Laurenceb_> yeah its like 6dB or something
[11:18] <Laurenceb_> dominoex FTW

[11:35] <astrobiologist> Matt's stuff went over my head, but I wonder if those of us who fly linux boards etc could use existing libraries as a quick fix to implement Turbo Code etc
[11:35] <Sven_> +Ja Hallo DL1SGP
[11:35] <craag> astrobiologist: There aren't many libraries around for that I found.
[11:36] <craag> (Just finished a project in comms simulation)
[11:36] <astrobiologist> http://users.ecs.soton.ac.uk/rm/resources/matlabturbo/
[11:36] <tweetBot> @destinysagent: Fantastic translation for Alan #ukhas #Hipstamatic #Oggl http://t.co/Qc8zWccxYl
[11:36] <Sven_> No Ballonstart today?
[11:36] <craag> But if someone writes one in C, it'll hopefully be portable!
[11:36] <astrobiologist> Robert Maunder seems to have something with the words linux and Turbo Code on the same page
[11:37] <craag> There's a lot of simulation libraries, not many tailored towards implementation
[11:37] <craag> Yes, Rob Maunder was my comms lecturer, he knows what he's talking about!
[11:38] <craag> That turbo encoder will be easy in C/arduino.
[11:40] <mattbrejza> astrobiologist: the encoding is trivial
[11:40] <craag> The great thing is that we can really utilise CPU power of powerful machines on the ground to improve the link.

[11:41] <navrac_work> but if we are only sending 20byte packets - is there really any great advantages - the slides seemed to be about much larger block sizes which are only good for images/video
[11:42] <mattbrejza> 1000bits isnt that much bigger
[11:42] <mattbrejza> you can use turbo codes down to 48bits in lte
[11:43] <mikestir> there are a couple of LGPL VHDL turbo decoders on opencores that might be a useful basis for a software implementation
[11:43] <navrac_work> but if we are sending reference frames then differences a typical packet may fall to only a few bytes,
[11:44] <craag> But then if we lose the reference frame?
[11:44] <navrac_work> true
[11:44] <craag> Matt mentioned sending a reference and a bunch of differences in the same packet.
[11:44] <craag> THat works quite well if you're happy with a bit of latency.
[11:44] <Willdude123> Who's doing the talk in French?
[11:44] <mattbrejza> yea every frame shoukd really have at least one absolute position
[11:45] <navrac_work> it seems to me the biggest gain would be to send the confidence data witrh each bit and use habitat to come up with the final packet, local qrm seems to be the killer
[11:45] <Willdude123> I my french isn't that good :)
[11:45] <craag> navrac_work: Yeah me too.
[11:45] <mattbrejza> tbh its more to get >1hz updates
[11:45] <mattbrejza> different league of update freq really

[11:46] seventeen (021bf710@gateway/web/freenode/ip. joined #highaltitude.
[11:46] <Laurenceb_> very clear to see everything there
[11:46] <craag> SSDV at 6kbits/s would be nice.
[11:46] <mattbrejza> how shitty were they on the stream
[11:46] <Laurenceb_> id be nice to see some of the existing modes
[11:46] <navrac_work> do we need that sort of update rate - i guess we are all doing different things with balloons so what is good for some is not going to be for others
[11:46] <Laurenceb_> they were quite clear
[11:46] <mattbrejza> :-)
[11:46] <Laurenceb_> i suspect dominoex with FEC is going to be pretty good
[11:46] <fsphil> 6kbit/s would allow for some higher quality images
[11:47] <mattbrejza> you could use the turbo code with standard rtty ascii if you wanted
[11:47] <fsphil> how fast could dominoex/thor be pushed?
[11:47] <mattbrejza> domex uses too much bw
[11:47] <daveake> yes fast SSDV would be very nice.
[11:47] <fsphil> aye
[11:47] <daveake> Also, on SSDV flights the SSDV works much better than telemetry, so it would be great for everything to get the error correction on those
[11:48] <mfa298> so how long until 24 images per second ssdv
[11:48] <Laurenceb_> mattbrejza: ive flown MFSK-64 a few times
[11:48] <mattbrejza> not in 3khz mfsk
[11:48] <Laurenceb_> works very well
[11:48] <fsphil> you'd need megabits mfa298 :)
[11:48] Action: daveake stares at fsphil
[11:48] <mattbrejza> tbh video in 300kbit will do
[11:48] <Laurenceb_> but itd need a bit of attention to work well with SSDV
[11:48] <fsphil> the smallest image you can have with ssdv atm is 256 bytes
[11:48] <mfa298> and as matt said, more error correction as it comes down could be good.
[11:49] <Laurenceb_> FEC and varicode removed and stuff
[11:49] <craag> 10fps video can be done at 100kbit, maybe even 50kbit.
[11:49] <mattbrejza> 256bytes not bits
[11:49] <Willdude123> Who is the current speaker?
[11:49] <fsphil> you'd need about 50kbit/s for 25fps with the smallest image
[11:49] <mattbrejza> f6faq
[11:49] <daveake> Takes about 5 mins for a decent sized image (5xx x 384) @ 600 baud rtty
[11:49] <Laurenceb_> yeah tbh i think the "killer app" for really well done coding and modulation is video
[11:49] <craag> Willdude123: Alain from Calais
[11:49] <Laurenceb_> dominoex with fec is pretty good for position and stuff
[11:49] <fsphil> but if doing video I wouldn't use ssdv in its current form

[12:38] <SpeedEvil> Are you planning on a holiday to finland?
[12:38] <mikestir> lol no
[12:38] <mikestir> and doesn't look like they'll be back over here for a while
[12:39] <Laurenceb_> i was calculating He diffusion rates in mylar yesterday
[12:39] <Laurenceb_> i calculated about 10days flight time
[12:40] <Laurenceb_> but the aluminium helps a lot
[12:40] <Laurenceb_> so i dunno lol - maybe 3 weeks
[12:40] <mikestir> well B11 is, what, 6 days now with no significant change in altitude
[12:40] <mikestir> so it can't be losing it that fast
[12:41] <Laurenceb_> i dont think you can tell
[12:41] <Laurenceb_> the altitude doesnt change as gas is lost
[12:41] <mikestir> would you expect it to reach a critical point and just drop?
[12:41] <Laurenceb_> yes
[12:42] <DL1SGP> or syrians using a SAM against it :)
[12:43] <SpeedEvil> Laurenceb_: what's the superpressure? A few tens of millibars?
[12:43] <Laurenceb_> if you can keep the Al on the envelope and use H2 to fill it - 3 weeks flight time
[12:43] <Laurenceb_> about 4000Pa
[12:43] <SpeedEvil> wow
[12:43] <SpeedEvil> Were any special measures taken on the valve?

[12:46] <SpeedEvil> i just find it amazing that it's not got tiny pinholes, and the valve is tight to make the permeability actually important
[12:46] <Laurenceb_> i think its a flap valve
[12:46] <Laurenceb_> so it seals itself quite well
[12:46] <Laurenceb_> im guessing holes is a question of careful handling

[14:25] <SpeedEvil> 'Unlike standard propellers that turn at subsonic speeds, the outer 2430 inches of the blades on the XF-84H's propeller traveled faster than the speed of sound even at idle thrust, producing a continuous visible sonic boom that radiated laterally from the propellers for hundreds of yards.'

[16:34] <Sven_> Hoffe man kann das verstehen Lunar?
[16:34] <fsphil> will talk shortly Sven_, just packing up here
[16:35] <enkidu> nice piece of antenna. I will have no reception here I think. side of hill blocking even reception from 100kW rated station
[16:36] <Lunar_Lander> ja
[16:37] <Lunar_Lander> Sven_, wir können ja schauen dass ich übersetze wenns schwierig wird
[16:37] <Lunar_Lander> fsphil, I can interpret if there are language difficulties

[16:47] <Maxell> This WebSDR could hear B-11 perhaps?
[16:48] <Maxell> It advertises 433.988 - 435.012 MHz and is in the last position horizon of B-11.
[16:50] <DL1SGP> according to the log there were folks trying to hear B-11 on there, have not checked myself though
[16:54] <Maxell> I don't want to install Java, and the only machine that runs Java that I have control has network problems
[16:55] <Maxell> I shoul'd have investigate that list of WebSDR earlier.
[16:55] <DL1SGP> heh I am feeling the same way Maxell
[16:56] <DL1SGP> but I might bring up the Big Computer and run a VM with Java
[16:57] <DL1SGP> guess need to decide quick, B-11 should be in darkness soon

[17:03] <DL1SGP> could relate to the site, could have other reason, I will try to get some signal out of it and hopefully we get a last sign of life from B-11 birdie before it goes to sleep
[17:03] <navrac_work> I'm on it with sound etc - but nothing heard
[17:04] <enkidu> shouldnt B-11 broadcast even at night?

[17:07] <Maxell> :P
[17:07] <navrac_work> since half of poland appears to be listening out, I'm sure we should get something out of B11

[18:50] <LeoBodnar> Did B-11 stop transmitting or went out of range?
[18:51] <DL1SGP> I would say out-of-range
[18:52] <enkidu> we had few trajectories for it and it will either stay here (where military might want to take it down) or move over ukraine
[18:52] <LeoBodnar> I see :)
[18:52] <DL1SGP> I hope it shows up again some time :)
[18:52] <enkidu> we will look for it
[18:53] <LeoBodnar> What location you are in enkidu ?

[19:42] <LeoBodnar> Hey G0TDJ_Steve it was really cool to see you today!
[19:42] <SP3OSJ> What it is: A "liitle helium" may have to be a little helium?
[19:42] <G0TDJ_Steve> Likewise LeoBodnar :D
[19:42] <enkidu> yep, misstyping too often last time
[19:44] <LeoBodnar> Too little helium and it will come down after getting iced up. Too much helium and it will rupture under increased pressure from the Sun. It's a very fine balance
[19:44] <G0TDJ_Steve> OK One job done. Now to transfer the conference pics to my PC :-)
[19:45] <LeoBodnar> G0TDJ_Steve do you know when will they put videos online?

[19:46] <SP3OSJ> Leo write on your website exactly as it did. I will read and I will do so as a description of!
[19:46] <LeoBodnar> :)
[19:48] <SP3OSJ> How this balance (helium) to calculate
[19:49] <enkidu> easy way is to calculave volume of helium at desired baric level
[19:49] <SP3OSJ> Write a book. I want to buy it
[19:49] <LeoBodnar> Add exact amount of extra weight (e.g. 2 grams) and make it neutral buoyant so it does not go up or down
[19:50] <LeoBodnar> Then remove extra weight

[19:51] <SpeedEvil> LeoBodnar: it would also be interesting to measure - on the ground - the burst pressure
[19:52] <LeoBodnar> RocketBoy did it
[19:52] <SpeedEvil> oh
[19:53] <SP3OSJ> So tracker: 22g. Fill the balloon to increase the weight of 24g - is OK?
[19:54] <LeoBodnar> http://ukhas.org.uk/projects:splat
[19:54] <SpeedEvil> Add a 2g weight to your tracker. Fill until it is neutrally bouyant. Remove the wegith

[19:55] <SpeedEvil> interesting - splat
[19:55] <SP3OSJ> By now I read. Tomorrow my balloon flies again
[19:55] <LeoBodnar> SP3OSJ: Add 2 gram weight to your tracker, make the balloon to float without going up or down (+- 0.5 gram is OK)
[19:55] <LeoBodnar> Remove the extra weight
[19:56] <LeoBodnar> OK SP3OSJ :)

[21:32] <LeoBodnar> Do you know why I should talk to you? :)
[21:32] <Laurenceb_> cuz im awesome?
[21:33] <LeoBodnar> It has been mentioned today yes
[21:33] <Laurenceb_> i suspect using MCO from a microcontroller is actually a silly idea
[21:33] <Laurenceb_> - for 22m
[21:34] <Laurenceb_> due to lack of precision tuning, as you said
[21:34] <Laurenceb_> but if i understand correctly the phase noise isnt so bad, which is interesting
[21:35] <LeoBodnar> It could be worth trying as you have PLL essentially for free. I love minimalist design and hardware hacks.

[22:48] <Guest3398> hello all...i'm wondering if anyone have sucessfully managed to work with the ublox max6 gps via I2C in the raspberry pi
[22:48] <G0TDJ_Steve> enkidu: Do you think it's heading your way?
[22:49] <enkidu> it will pass over lithuania I think

[22:49] <G0TDJ_Steve> So there's a chance you'll get some decent sentances then
[22:49] <enkidu> but it was received in predicted direction
[22:49] <enkidu> same as with B-12. passed over me and one reception? :P
[22:49] <Lunar_Lander> hi eroomde
[22:50] <Lunar_Lander> cool talk on GPS
[22:50] <Lunar_Lander> thank you for that
[22:50] <G0TDJ_Steve> I would have liked to have seen the GPS talk. Glad it went well.
[22:50] <eroomde> np
[22:50] <eroomde> ty
[22:50] <eroomde> glad it actually worked at the end
[22:50] <enkidu> I can see its beeps tho
[22:50] <eroomde> was a bit nervous

[22:51] <enkidu> again noise
[22:51] <G0TDJ_Steve> Keep trying
[22:51] <enkidu> 21.7229
[22:52] <enkidu> have strong signal few khz nearby
[22:52] <G0TDJ_Steve> Ahh, not good
[22:52] <G0TDJ_Steve> Got any filtering?
[22:52] <enkidu> not so narrow
[22:52] <enkidu> I filtered everything below 400MHz

[22:54] <mrShrimp> Hi, I was wondering if anyone could help me to set up DL-FLDIGI for receiving the signal sent by the code at the bottom of this page?: http://ukhas.org.uk/projects:dl-fldigi

[22:55] <G0TDJ_Steve> mrShrimp: I'd be happy to help another day. I'm back from the conference today and I'm shattered.
[22:55] <mrShrimp> Okay, I will try to work it out on my own now.
[22:55] <G0TDJ_Steve> Don't forget you need the DLFlDigi (HAB Mode) version
[22:55] <mrShrimp> Oh, the HAB mode needs to be running?
[22:55] <mrShrimp> I'll try that
[22:56] <G0TDJ_Steve> It's the only one that will work with HABs ;-)
[22:56] <G0TDJ_Steve> Goodnight all

[23:01] <enkidu> radiosonde lounching time, hard choice, but B11 needs me
[23:01] <Laurenceb_> good job its heading south
[23:02] <enkidu> any Idea how to get rid of noise and decode better?
[23:02] <mattbrejza> Laurenceb_: im sure its not that bad - too far north really ;)
[23:02] <enkidu> DSP filter / FEC?
[23:03] <bertrik> enkidu: disable the squelch in dl-fldigi if you haven't already
[23:03] <enkidu> I did
[23:03] <enkidu> also in gqrx
[23:03] <mattbrejza> to get rid of noise liberally apply liquid helium
[23:03] <enkidu> also, I enabled direct routing in pulseshit
[23:04] <enkidu> or use tomahawk
[23:04] <enkidu> bertrik: in dominoex options there is checked filtering, FBW=2, and FEC unchecked

[23:23] <mrShrimp> Would anyone mind helping me setting up DL-FLGIDI?
[23:23] <enkidu> dont know why fldigi consider signal as noise
[23:24] <fsphil> DanielRichman: tried again through a proxy. seems to be hotel wifi
[23:24] <fsphil> loaded fine through that
[23:24] <mrShrimp> The signal from the NTX2 sounds perfectly fine, but it doesn't seem to be decoding correctly
[23:25] <fsphil> usual things: make sure SQL is off, make sure both radio and fldigi are set to USB
[23:25] <fsphil> try toggling Rv -- if it needs to be selected, and both radio and fldigi are in USB, then your payload is transmitting the tones backwards
[23:26] <enkidu> no, order is proper
[23:26] <enkidu> from what I seen, its just over horioz
[23:26] <enkidu> horizon*
[23:27] <fsphil> oh this is not your payload?
[23:28] <crash_18974> are any web based radios hearing b-11 now?

[23:29] <mrShrimp> Thanks, it is working now! I apparently need to take a closer look at the FLDIGI instructions; I had the dropdown set to RTTY instead of USB.
[23:29] <fsphil> yes, confusing that
[23:29] <fsphil> RTTY for some reason is LSB
[23:29] <fsphil> RTTYR is USB
[23:29] <fsphil> but easier just to use USB proper
[23:30] <fsphil> I'm sure there's some historical reason for that
[23:30] seventeen (021bf710@gateway/web/freenode/ip. left irc: Quit: Page closed
[23:31] <bertrik> Isn't there some general rule that stuff below 10 MHz in usually LSB and above 10 MHz it's USB?
[23:31] <fsphil> for audio, not so much digi modes. though rtty is ancient so possibly applies to that
[23:32] <mfa298> the change at 10MHz does seem to be a convention but the reasons are probably lost in the mists of time
[23:32] <fsphil> although below 10mhz if both transmitter and receiver where in LSB
[23:32] <fsphil> the tones would still be the right way
[23:33] <fsphil> (well not specific to below 10mhz)
[23:33] <fsphil> possibly commercial rtty services used to have the stop bit as the lower tone
[23:35] <gonzo_> I think all amateur rtty is USB, even below 10MHz

[23:46] <mikestir> I think the reason for the change is that bands below 10 MHz used to be shared, and commercial all used USB (for voice), so amateur used LSB
[23:47] <mikestir> and possibly "RTTY" in fldigi is relative to LSB because amateurs would just shove the output of the modem into their voice rig configured for LSB
[23:48] <fsphil> that would make more sense
