[00:00] <Geoff-G8DHE-Lap> Love the Hexhagonal pole wind structure!
[00:00] <Geoff-G8DHE-Lap> Hexagonal*
[00:00] <MikeUoN> Does Jupiter have that as well as Saturn?
[00:00] <Geoff-G8DHE-Lap> still not right too much alchol!
[00:01] <Geoff-G8DHE-Lap> Yer maybe Saturn mixing me planets
[00:01] <MikeUoN> close enough for me too understand ;)
[00:02] <MikeUoN> I got to call it a night, apologies if I rustled any feathers asking for help with SDR# ;-;
[00:02] <Geoff-G8DHE-Lap> Actually the forecast was right its quite clear but not dressed now and too much Port!

[08:07] <R34lB0rg> they launch two times a day using disposable telemetry devices
[08:08] <Vaizki> They all do
[08:08] <R34lB0rg> and after the new regulations they have a permission limited to these devices
[08:08] <R34lB0rg> he told they couldn't even launch a camera if they wanted to

[09:43] <Vaizki> so allllll the snow is gooooone
[09:43] <fsphil> and I thought UK waather was changeable :)

[09:44] <Geoff-G8DHE-Lap> Who says its going to be windy down here then ? Not on my forecast??
[09:45] <fsphil> bbc are saying 80km/h gusts for here. lovely
[09:45] <fsphil> thursday looks to be even worse
[09:45] <cm13g09> Geoff-G8DHE-Lap: Accuweather are showing up 80km/h gusts
[09:45] <Geoff-G8DHE-Lap> For NI ?
[09:45] <fsphil> for mine yeah
[09:45] <Geoff-G8DHE-Lap> here is my forecaster http://www.yr.no/place/United_Kingdom/England/Worthing/hour_by_hour_detailed.html
[09:46] <Geoff-G8DHE-Lap> Strong Breeze at worst
[09:46] <Vaizki> oh that's a nice forecast format
[09:46] <daveake> I use wunderground for this e.g. http://www.wunderground.com/cgi-bin/findweather/hdfForecast?query=ross+on+wye&MR=1
[09:47] <Geoff-G8DHE-Lap> They use Met. office data but use the average not worst case AIUI.
[09:47] <fsphil> it's a bit annoying that the bbc switch to gusts speeds when the average gets above 20mph
[09:47] <cm13g09> fsphil: lol
[09:48] <Vaizki> I like the cloud cover representation on the graph
[09:48] <daveake> cos bigger numbers sound more impressive

[09:48] <Geoff-G8DHE-Lap> For wunderground then http://www.wunderground.com/cgi-bin/findweather/getForecast?query=pws:IENGLAND613
[09:48] <Vaizki> it's a bit outdated but compact to check out on an iphone (they have a really old app)
[09:48] <fsphil> heh, wunderground is saying we've got a good chance of snow this weekend
[09:49] <Geoff-G8DHE-Lap> Yes the Cound cover is great for astronomy frecast easy to read!
[09:49] <Vaizki> wunderground says "Ice Pellets" for me :(
[09:49] <Vaizki> what is that even.. hail?
[09:50] <Geoff-G8DHE-Lap> big hail perhaps!
[09:50] <Vaizki> Ice pellets are also called sleet and can be accompanied by freezing rain.
[09:50] <Vaizki> ok sleet I know.
[09:50] <Vaizki> and hate
[09:51] <Geoff-G8DHE-Lap> Right more coffee!
[09:53] <x-f> ice pellets are small ice bits, and when they accumulate a few centimeters on the ground, they are very heavy to shovel off

[11:54] <craag> Morning folks
[11:54] <craag> Thanks for tracking CRAAG4 yesterday
[11:55] <AndyEsser> I wasn't able to :(
[11:55] <adamgreig> we've been eagerly awaiting the story
[11:55] <SA6BSS-Mike> goinng back for another look for the payload?
[11:55] <AndyEsser> but I tried
[11:56] <craag> "How not to HAB" - in a day
[11:56] <eroomde> give us the breakdown
[11:57] <craag> So I got involved with this in just providing a backup tracker, and driving people up.
[11:57] <eroomde> yes we don't hold you responsible for the fustercluck
[11:57] <craag> Sensor payload was built the night before, using arduino, breadboard and those push-in wires, taped to a piece of cardboard
[11:58] <SA6BSS-Mike> can understand the need for a backuptracker
[11:58] <craag> The architect of this hadn't been able to verify it was actually recording anything, due to not having an sd card reader, so it all had to be tested on site
[11:58] Action: eroomde gets his hab-fail bingo card out
[11:58] <craag> of course it didn't all work
[11:58] <mattbrejza> so what was the primary tracker?
[11:59] <craag> primary tracker was an 'allreach'? satellite modem
[11:59] <craag> 'onreach'
[11:59] <AndyEsser> eroomde: We so need those
[11:59] <craag> something like that
[11:59] <eroomde> two clueless undergrads - 88
[11:59] <eroomde> helium bottle actually empty - 22
[11:59] <mattbrejza> balloon early burst?
[11:59] <craag> so this flight involved an experiment with bugs in a sealed container
[12:00] <AndyEsser> as in... actual bugs?
[12:00] <eroomde> what was the nebula payload?
[12:00] <AndyEsser> not... software bugs?
[12:00] <R34lB0rg> oh, no!
[12:00] <craag> actual bugs
[12:00] <Vaizki> what..
[12:00] <SA6BSS-Mike> :)
[12:00] <mattbrejza> something something another uni's project?

[12:00] <craag> there are major political things about this that I'm not going to mention here - but need to talk to susf about before this happens again
[12:01] <craag> anyway
[12:01] <daveake> Feel free to edit my "how not to hab" document :)
[12:01] <craag> these sensors went in with the bugs
[12:01] <craag> and so the container needed to be expoxied up onsite
[12:01] Hix (~hix@151.224.160.9) joined #highaltitude.
[12:01] <craag> due the sensor issues, this didn't happen til gone 1pm
[12:02] <R34lB0rg> did they have a permission to launch for that time? or was it not required?
[12:02] <daveake> they had permission for that time
[12:02] <craag> They had a notam
[12:02] <craag> that was fine
[12:02] <daveake> about 30 mins left on it :)
[12:02] <craag> so that was the main cause of the delay
[12:03] <craag> so I then started filling the balloon, by this time they found out the payload box wasn't big enough, so duct tape and other bits brought it up to ~3.5kg
[12:03] <craag> estimated as they'd forgotten scales
[12:03] <daveake> hah
[12:04] <craag> so we just emptied the tank into the balloon
[12:04] <craag> and then the wind picked up..
[12:04] <Vaizki> maybe you need a non-negotiable checklist of prerequisites for project to get involved with :O
[12:04] <Vaizki> sounds awful
[12:04] <R34lB0rg> sound like an act of desperation
[12:04] <craag> 1200g unknown brand
[12:04] <Vaizki> and 3.5kg payload?
[12:05] <craag> they had a arduin+gps shield+relay shield cutdown thing
[12:05] <craag> which was programmed for a cutdown of 52.2 lat
[12:05] <R34lB0rg> untested of course
[12:05] <craag> in hindsight, he may have typoed that to 52.0
[12:05] <craag> that was tested - had been used on 10+ flight before
[12:06] <Geoff-G8DHE-Lap> Well did they LEARN from the experience ?
[12:06] <mattbrejza> cutdown at 51.96535,-3.265131
[12:06] <mattbrejza> last position 51.99983,-3.159434
[12:06] <mattbrejza> well cutdown or burst?
[12:07] <craag> mattbrejza: arduino gps shield though, could have had some position noise?
[12:07] <Vaizki> so did they appreciate your heroic efforts to save their ass?
[12:07] <eroomde> Geoff-G8DHE-Lap: i know some of the people behind an aspect of that launch, and would observe the learning takes some humility
[12:07] <craag> So then after wrestling with the balloon in the rain for another 30 mintues while the epoxy actually dired
[12:07] <craag> *dried
[12:07] <craag> we launched
[12:07] <M0XIN> "dired" seems more appropriate
[12:07] <craag> went up quick
[12:07] <craag> jumped in the cars
[12:07] <craag> got going
[12:08] <craag> then it started coming back down
[12:08] <eroomde> and humble learning is less exciting that being a visionary space entrepreneur
[12:08] <craag> so - set off for landing
[12:08] <mattbrejza> dont suppose their tracker even let them know it had burst
[12:08] <craag> we only had the last radio position at 2.5km or so
[12:08] <craag> they had one ping off the sat modem at 3km on the way down
[12:09] <mattbrejza> also 52.0 <-> 51.96 is still quite a bit error? although perhaps not in hte lassen days
[12:09] <mattbrejza> oh ok
[12:09] <craag> but didn't notice the altitude - so insisted on heading straight for that first
[12:09] <craag> so by the time we got to predicted landing - it was dark
[12:10] <craag> I got out the yagi and found the signal from my tracker, but it had failed to CW carrier
[12:10] <craag> :(
[12:10] <Vaizki> ntx2b with en permanently tied to vcc?
[12:10] <mattbrejza> rfm98
[12:10] <Vaizki> ah ok
[12:10] <craag> ^^
[12:10] <daveake> THE carrier thing happened on the way down
[12:10] <craag> (lucky!)
[12:10] <craag> oh :(
[12:11] <craag> I'd had some issues with it the day before, but then reflashed and it was fine
[12:11] <daveake> Not sure when exactly as I was switching over to lora. Got nothing so had a listen.
[12:11] <craag> hmm ok
[12:11] <mattbrejza> the tracker had a wdt, so that should have been continuously resetting the micro
[12:11] <daveake> Someone mentioned it here before I noticed
[12:11] <craag> so we kitted up and set off across the hillside with yagi+fcdpp+laptop
[12:11] <mattbrejza> so the rfm98 was perhaps unresponsive
[12:12] <mattbrejza> did all of you go?
[12:12] <Geoff-G8DHE-Lap> It had some modulation oddities during the flight on the RTTY side I noticed.
[12:12] <craag> gradually the susf guys peeled off and headed back due to the terrain, Sam, his friend Dan, and myself pushed on
[12:13] <Vaizki> craag, ouch.. a ft-817nd might have been nicer than a fcdpp :O
[12:13] <craag> we walked for about 2 hours across streams, up and down the little valleys, with it getting stronger nad stronger
[12:13] <craag> Vaizki: yes...!
[12:14] <craag> eventually noticed this large patch of trees (~1 mile across) on the hillside a couple of miles away
[12:14] <craag> (it was properly dark by then)
[12:15] <craag> We then hit another road, so followed that down the hill, took another bearing from there that confirmed the trees. But we'd had no phone signal and so headed back along the road to the cars.
[12:16] <craag> We got back to the cars about an hour later to find that the guys waiting there had called the police and reported us lost
[12:16] <daveake> lol
[12:16] <dbrooke> I commented in IRC on a sequence counter reset and also the carrier if you want to check the log for times
[12:17] <craag> in hindsight, I had a vhf handheld in my backpack, and one of hte guys back at the car also did (and called me on it), but I didn't remember about it.
[12:17] <Vaizki> you don't repoer a group of 3 guys lost after an hour or two :O
[12:17] Hix (~hix@151.224.160.9) left irc: Remote host closed the connection
[12:17] <Vaizki> a single stumbler in the dark, maybe
[12:17] <criticalmass> Huzzah, Craag updates. Bear with me while I catch up :
[12:17] <mattbrejza> people waiting at the cars arnt known for their outside credentials
[12:17] <craag> Vaizki: Yeah they said the police didn't seem too concerned, they did turn up as we got back though and weren't too unhappy about it.
[12:17] <Vaizki> craag, so you know it's in a tree and you know where the tree is?
[12:18] <craag> It's brb
[12:19] <Vaizki> well after that story I now have to look at this for 20min to regain my inner peace.. http://www.buzzfeed.com/lukebailey/satisfying-cables#.cfArk0bZM
[12:20] <gonzo_> you could have roped the police into the search
[12:21] <gonzo_> like phoning an anon tip that you think there may be a body buried in the garden, when you need it digging over
[12:22] ibanezmatt13 (~ibanezmat@nat-0-169.soton.ac.uk) left irc: Quit: Leaving

[12:23] <AndyEsser> Vaizki: given I'm having a mountain of IT problems today - this page is helping
[12:23] <eroomde> 'yes officer, the corpse is transmitting on 434.65.....;
[12:23] <AndyEsser> 434.300 iirc
[12:23] <AndyEsser> :P
[12:23] <Geoff-G8DHE-Lap> No no 434.3 and its clled Lora
[12:24] <daveake> Well if it was .650, cause of death would be "attacked by an angry group of hams"
[12:24] <gonzo_> grumped to death
[12:24] <Geoff-G8DHE-Lap> :)
[12:25] <eroomde> i propose please that 'hemorrhoid' should be the collective noun for plural angry hams
[12:25] <eroomde> 'he was killed by a hemorrhoid of hams'
[12:26] <gonzo_> that would be an arse
[12:27] <gonzo_> no officer, I didn't say killed by agricultural workers, I said, by farmers

[12:30] <AndyEsser> craag: put you off habbing for life?
[12:30] <fsphil> he might need some time in rehab
[12:30] <AndyEsser> *facepalm*
[12:30] <Chimpusmaximus> :-)
[12:32] <mattbrejza> so at the top of a tree there is a 3kg sealed box with some poor bugs in it
[12:32] <mattbrejza> and a load of tape, wires and breakout boards
[12:33] <gonzo_> mattbrejza, when you refered to " outside credentials", did you mean they were not outdoors people, or they are not allowed out unaccompanied?
[12:34] <mattbrejza> outdoors people (i am just assuming here though)
[12:34] <craag> I'd agree ^^
[12:34] <craag> So then we got back in the cars
[12:34] <Laurenceb_> yay UBSEDS13
[12:34] <Laurenceb_> battery almost dead tho, its not going to make it to us
[12:34] <craag> hooked up the fcdpp to the magmount and drove around to see if it peaked
[12:34] <craag> it didn't
[12:34] <mattbrejza> !track UBSEDS13
[12:34] <SpacenearUS> 03mattbrejza: Here you go - 12http://tracker.habhub.org/#!qm=All&q=UBSEDS13
[12:35] <craag> confirmed in hilltop trees
[12:35] <craag> so we drove back
[12:35] <craag> got back ~1am
[12:35] <mattbrejza> oh wow thats caught some strong wind

[12:39] <mattbrejza> why did sam think that giving one day for hector to do the electronics would end well?

[12:49] T-MaN (~thomas@217.21.233.78) joined #highaltitude.
[12:55] <craag> mattbrejza: The new recruits enjoyed most of it, and are totally educated in the fact of that *not* being representative of a susf launch.
[12:57] <craag> They want in on the next launch :)
[12:58] <mfa298> craag: better or worse than blast ?
[12:58] <craag> worse
[12:58] <craag> I haven't even started on payload/parachute design..
[12:59] <craag> (I assume people say how fast it came down)
[12:59] <craag> *saw
[12:59] <gonzo_> too heavy, or the chute detached, tangled?
[13:00] <mfa298> I suspected it might have been worse, and I used to think that was *the* demonstration of how not to do it with nothing being able to be worse
[13:06] <Geoff-G8DHE-Lap> Do you have a Lat Long for the likely landing position
[13:08] <craag> one minute
[13:08] <Geoff-G8DHE-Lap> I'll add it to the KML file of the flight

[13:14] <craag> somewhere around 52.042,-3.088 we think
[13:14] <craag> in that large wood
[13:14] <craag> access road was blocked
[13:15] <craag> blocked by mud
[13:15] <Geoff-G8DHE-Lap> Yup see it OK will add it to the KML file that is here http://360.g8dhe.net/HAB_Flights/2016_Flights/CRAAG4_20160124/

[13:46] <MikeUoN> hehe
[13:46] <craag> I have photos of launch prep - I'll put them up tonight
[13:47] <R6mco> oh oh
[13:47] <craag> Annoyingly no photos of our countryside rambling - we were all quite focused for that.
[13:48] <R6mco> there are no WSPR decodes from PS-58 from 1330z
[13:48] <daveake> Summary photo: http://i.imgur.com/ulIVoNY.jpg
[13:48] <craag> murican payload also appropriate ;)
[13:48] <daveake> :)
[13:48] <MikeUoN> 'murican?
[13:49] <daveake> Upu will be along in a minute - he has that one as a desktop shortcut
[13:49] <UpuWork> https://dl.dropboxusercontent.com/u/63720513/Images/Funny/pico.jpg
[13:50] <R6mco> if there are no decodes from 1400z I have great fear
[13:50] <MikeUoN> ok ROFL
[13:50] <UpuWork> and landing http://i.imgur.com/36s5f.gif
[13:50] <MikeUoN> Brilliant xD
[13:51] <MikeUoN> I think that is really very funny xd
[13:51] <eroomde> that was back in the days when americasn insisted you couldn't do hab with less than a 5W handheld for telemetry
[13:52] <AndyEsser> less than 5W?!
[13:52] <MikeUoN> I remember coming across a website of a group that seems to be trying to get a balloon on Venus. Not sure how they are even going to get there though... :P
[13:52] <MikeUoN> LoL, pretty sure you can get across the world on 5W xD
[13:52] <R6mco> Geoff-G8DHE-Lap: what is the datamode of CRAAG4, RTTY on 70cm?
[13:53] <mfa298> also that a payload could never be under <1kg
[13:53] <mfa298> luckily arko came along and showed them how to do it.
[13:53] <MikeUoN> really O>o
[13:53] <MikeUoN> nice
[13:53] <craag> R6mco: Prefix of RTTY, LoRa, then the main mode of very very slow CW
[13:54] <daveake> hah
[13:54] <R6mco> frequency ?
[13:55] <craag> That was an annoying fault on my part - it had been dodgy the day before but seemed ok after a reflash
[13:55] <craag> If it was the primary tracker I wouldn't have flown it solo
[13:55] <craag> R6mco: It's very landed.
[13:55] <craag> I'm reasonably sure ;)
[13:55] <R6mco> craag: what is the frequency ?
[13:56] <craag> R6mco: was 434.300
[13:56] <craag> and will be out of batt now anyway
[13:56] <R6mco> rgr
[13:58] <fsphil> MikeUoN: there have already been HABs on venus :)
[13:59] <R6mco> within one minute PS-58 will start transmitting WSPR ... if it still flies
[14:01] <MikeUoN> Cool, I suppose you could use just plain earth air on Venus?
[14:01] <fsphil> well, anything lighter than carbon dioxide
[14:01] <fsphil> these used helium
[14:01] <fsphil> https://en.wikipedia.org/wiki/Vega_program#Balloon
[14:02] <MikeUoN> Oh that's very cool
[14:02] <MikeUoN> THe group I came across were nowhere near as advanced as that though :p
[14:03] <fsphil> 2048 bits/s -- on another planet and in the 80s, and still faster data rate than we usually have :)
[14:04] <MikeUoN> pretty impressive
[14:04] <fsphil> the only other place a balloon would be practical is titan I think
[14:05] <fsphil> maybe mars, but the air is so thin
[14:09] <SpeedEvil> ass giants
[14:09] <SpeedEvil> gas
[14:09] <R6mco> ok
[14:10] <SpeedEvil> venus too
[14:10] <MikeUoN> Aren't they mainly hydrogen
[14:10] <SpeedEvil> Mostly, yes.
[14:10] <R6mco> I think PS-58 unfortunately splashed around 1303z
[14:10] <SpeedEvil> Zulus. 1300s of them.
[14:10] <fsphil> ass giants are something else entirely
[14:11] <AndyEsser> resists temptation to make "yo mamma" joke...
[14:11] <MikeUoN> ( a° \– a°)
[14:11] <daveake> Boldy going where man would rather not go
[14:11] <daveake> +l
[14:13] <Geoff-G8DHE-Lap> R6mco, What makes you think it splashed into the sea ?
[14:14] <R6mco> look at the WSPR decodes
[14:14] <R6mco> last JT9 decode is from 1200z
[14:14] <R6mco> last WSPR decodes, only 2 reports, are from 1300z
[14:14] <R6mco> (by two very good RX stations)
[14:15] <daveake> what was the reported altitude for those 3 decodes ?
[14:15] <R6mco> last JT9 packet around 1303 - 1304z is not received anymore
[14:15] <MikeUoN> PS balloons are so cool
[14:15] <R6mco> daveake: let me try to look that up
[14:15] <fsphil> I wouldn't count them out unless they're not heard from for a while, or the last position was showing it falling
[14:15] <Geoff-G8DHE-Lap> Umm the last one on habitat was at 11:32 and it was still at 9461m
[14:16] <R6mco> <- receives them often as only RX station on the northern hemisphere
[14:16] <fsphil> HF is quite unpredictable
[14:16] <daveake> as fsphil said
[14:16] <fsphil> it can go many hours without being hard from
[14:16] <fsphil> heard*
[14:16] <MikeUoN> Wait PS58 crossed the equator? O>o that is pretty epic
[14:18] <R6mco> fsphil: no, not in this case
[14:18] <R6mco> $$PS-58,1202,12:02:00,13.679,-46.295,9467,57.6,14,3,12.5,3807,800 0013 jt9 10.1387Mhz*F1E5",VE1VDM/1,1202,12:02:00,13.679,-46.295,9467,57.6,14,3,12.5,3.807,800 0013 jt9 10.1387Mhz
[14:18] <R6mco> JT9 decode
[14:19] <R6mco> from VE1VDM/1, he also was one of the two who decoded PS-58 on wspr
[14:19] <MikeUoN> I wonder if the PS balloons need to permission to launch, if they are >2m in size. Unless the Australian rules are way different,
[14:19] <Laurenceb_> ps-58 can go a day with no rx
[14:20] <Laurenceb_> and usually loses rx for 4 or 5 hours at a time during the day
[14:22] <R6mco> [15:19] <Laurenceb_> ps-58 can go a day with no rx <- not correct
[14:22] <R6mco> look at the database
[14:23] <Geoff-G8DHE-Lap> No sign of it decreasing in Alt at all http://360.g8dhe.net/HAB_Flights/2015_Flights/PS-58_20151229/
[14:23] <R6mco> PS-58 is decoded every day
[14:23] <R6mco> that was also the case with PS-57 ... and suddenly it splashed
[14:23] <R6mco> in the Indian Ocean
[14:24] <Geoff-G8DHE-Lap> Yes that is true
[14:24] <fsphil> largest gap reported by the SpacenearUS bot was 11 hours
[14:24] <R6mco> I monitored PS-57 quite extensively from here , got during grey line always the decodes
[14:25] <R6mco> fsphil: SNUS does not have full data
[14:25] <R6mco> that's why I said: look at the WSPR decodes
[14:26] <R6mco> there are FAR more people who decode WSPR than JT9, of which the latter -if they decode- don't use the special version of WSJT-X to upload JT9 spots to habhub.org
[14:26] <R6mco> habhub.org is not a good figure of merit for PS-57, 58 etc
[14:27] <R6mco> with WSPR there is an indication where the balloon resides, last decoded locator was/is GK63
[14:27] <Laurenceb_> well I'll be interesting if it has gone down
[14:28] <Laurenceb_> as that would make the flight time the same as PS-57
[14:28] <R6mco> me too, therefore I mention my analysis
[14:28] <R6mco> hopefully being wrong
[14:28] <Laurenceb_> I bet it will come back by nightfall
[14:31] <Laurenceb_> PS-57 looked like it popped, which was very odd
[14:31] <R6mco> AK4AT's last decode was -16 dB down to the decodes shortly before
[14:32] <R6mco> that was at 12.30z
[14:32] <R6mco> so that must mean (imho) that the balloon already lost height
[14:32] <daveake> Which suggests poorer propagation, not descent
[14:32] <daveake> Well not if the reported height was unchanged
[14:32] <R6mco> that's true indeed
[14:32] <R6mco> however, the last height information is from 1200z
[14:33] <R6mco> (or 1202z , to be more precise)
[14:33] <Geoff-G8DHE-Lap> Which db and callsign are you looking at wsprnet.org ?
[14:33] <daveake> So there was a decode at 12:30 that didn't include the altitude ?
[14:35] <R6mco> http://i.imgur.com/HMSHExy.jpg
[14:35] <R6mco> there was no JT9 decode from 1230
[14:35] <R6mco> Geoff-G8DHE: VK3ANH = PS-58 (or probably was ... )
[14:37] <R6mco> I think the balloon was already descending after 1202z and splashed after the last WSPR trace and approx. during the time the JT9 frame was transmitted.
[14:37] <R6mco> If it was at e.g. 500m height, I firmly believe VDM/1 was able to RX it. He as a SUPER RX station
[14:38] <R6mco> has*
[14:38] <daveake> As I'm a bit confused, can you just tell me the last known altitude and when that was?
[14:39] <R6mco> 1202z
[14:39] <daveake> ta
[14:39] <R6mco> this is the last rx'd JT9 packet:
[14:39] <R6mco> $$PS-58,1202,12:02:00,13.679,-46.295,9467,57.6,14,3,12.5,3807,800 0013 jt9 10.1387Mhz*F1E5",VE1VDM/1,1202,12:02:00,13.679,-46.295,9467,57.6,14,3,12.5,3.807,800 0013 jt9 10.1387Mhz
[14:39] <daveake> What confused me was that you said a packet had been decoded at 1230 ... so does WSPR not include alt ?
[14:39] <Laurenceb_> I see 2 hour gaps in the daya
[14:39] <R6mco> WSPR does not include altitude
[14:40] <daveake> ta now it all makes sense
[14:40] <R6mco> only locator
[14:40] <Laurenceb_> the WSPR
[14:40] <SA6BSS-Mike> daylight propogation, it will back tonight again :()
[14:40] <SA6BSS-Mike> :)
[14:40] <R6mco> yo Mike
[14:40] <R6mco> I hope you are right, but I fear with big fears ...
[14:40] <Laurenceb_> what SA6BSS said
[14:40] <Laurenceb_> there are often gaps of 2 or more hours during daylight
[14:40] <daveake> 1 last Q ... is this solar powered or solar recharged ?
[14:41] <Laurenceb_> when you look at historical WSPR
[14:41] <Laurenceb_> <daveake> well its been up 4 weeks so...
[14:41] <daveake> both options included the word "solar" ...
[14:41] <daveake> ... I'll ask another way ... does it have batteries ?
[14:42] <SA6BSS-Mike> its solar charged so it tx throughout the night
[14:42] <daveake> ta that's what I was after :)
[14:43] <R6mco> the last days PS-58 produced many decodes between this time of the day
[14:43] <Laurenceb_> propogation doesnt work like that :P
[14:43] <daveake> So just need to wait till nighttime to see if the improving propagation reveals its position

[14:43] <R6mco> Laurenceb: I know, tell me nothing about propagation ; -)
[14:44] <Laurenceb_> still, the PS-57 burst was off
[14:44] <Laurenceb_> *odd
[14:44] <daveake> aliens
[14:44] <R6mco> because I know the propagation , therefore it's odd that PS_58 is 'gone'
[14:44] <SA6BSS-Mike> it to far south, dalight permits usuly max 2000km of skip distance as night permits +6000km
[14:44] <R6mco> Mike: look at the historical data in olddb (select 2000 spots or so)
[14:45] <SA6BSS-Mike> it was closer to us last couple of days
[14:45] <R6mco> yep

[15:33] <habby> I think it is set as a float in gps.c

[15:34] <habby> Thanks :) Can you point me to where it is set, please?

[15:34] <mattbrejza> well this is where its read https://github.com/PiInTheSky/pits/blob/master/tracker/tracker.c#L109
[15:36] <mattbrejza> makes sense for a micocontrolelr tracker to use int32_t though
[15:36] <habby> Is it 2 or 4 bytes?
[15:36] <mattbrejza> or uint16_t if you dont care about -ve altitudes

[15:50] <daveake> passer-by, in deepest darkest Wales ? :)

[15:51] <AndyEsser> haha
[15:51] <craag> Secondly, thanks to some awful politics mess, the organisation details on the payload aren't the sponsoring organisation (and actually have officially nothing to do with it)

[17:45] <AndyEsser> mfa298: is it a large DB of actual data?
[17:45] <AndyEsser> I agree this is nothing in comparison to some of the DB's I've worked with
[17:45] <AndyEsser> but it's *shudder* MS SQL Server
[17:45] <AndyEsser> I'm just amazed it stayed up
[17:45] <mfa298> then again we have a table with something like 3.9 billion rows of actual real data
[17:45] <chris_99> wow, what DB engine is that stored in?
[17:46] <AndyEsser> Postgres or Oracle I'm guessing
[17:46] <mfa298> ours is in percona MySQL, with a fair bit of tuning
[17:46] <AndyEsser> MySQL?!
[17:47] <chris_99> ah interesting, percona, is like a tweaked version?
[17:47] <chris_99> https://www.percona.com/software/mysql-database/percona-server/benchmarks
[17:48] <mfa298> they have XtraDB (tweaked version of InnoDB) and pull in the Galera cluster extensions.
[17:48] <chris_99> ah, so it's running on >1 physical server?
[17:49] <mfa298> I think they also have some patches from MariaDB (and I think MariaDB pulls in XtraDB from percona)
[17:50] <mfa298> >1 server, but all servers have all the data and if anything performance is currently lower than a single server.
[17:50] <AndyEsser> Good lord. that delete operation cleared >4.5GB from the DB :)
[17:50] <chris_99> ah, because it has to synchronise transactions across them all i guess
[17:50] <mfa298> read performance could be improved as you can read from all servers, but writes generally go to one server and are replicated before the transaction commit completes.

[22:57] <AX5KX_Peter> Hi again Ivan !!
[22:58] <vk5hs> hi Peter nice morning ing renmark
[22:58] <Geoff__> Hi Guys what 2mtr freq is the chase using?
[22:58] <fsphil> flight in .au today?
[22:59] <AX5KX_Peter> It is a nice morning, Wendy & I are on top of a hill looking over Palmer...
[22:59] <R6mco> [23:45] <mattbrejza> reliable...? <-- more reliable than habhub
[22:59] <R6mco> there are more stations RXing
[22:59] <fsphil> habhub isn't a data mode
[22:59] <R6mco> (but upload decodes to another site)
[22:59] <vk5hs> looking at the flight path it will be you guys doing most of the tracking
[22:59] <R6mco> fsphil: I know
[23:00] <R6mco> I meant ... 'information habhub provides'

[23:00] <mattbrejza> a comms method which works if youre lucky and the conditions are right isnt reliable :P
[23:00] <fsphil> *information habhub is provided with
[23:00] <mattbrejza> but it does work pretty well, im not debating that
[23:00] <R6mco> okay ... you win ;; -)
[23:00] <mattbrejza> heh
[23:00] <AX5KX_Peter> Yep, an AUST flight today, it is Australia Day after all. Not sure about 2m freq yet, I have my radio in scan.
[23:01] <R6mco> <- was talked into this balloonsh*t by some people in the WSPR community, before that I didn't knew this community existed ;-)
[23:02] <fsphil> I'm not sure if wsprnet provide open access to their data
[23:02] <fsphil> via a reliable api
[23:03] <fsphil> seems not

[23:58] <R6mco> my recommendation ... take 'random' (not so random) wire
[23:59] <R6mco> make .. Beverage or BOG, like Mike Sa6BSS did!
