[03:46] <aadamson> so a little research turned up the cc1120/cc1200 (newer version) and sx1231 (doesn't do low vhf) as similar chips to the si parts... the ti's look a little more complex in R's and C's support around the part, and its a 5x5 32 pin qfn in it's smallest size... but things to look at in due time :)

[07:30] <skagmo> aadamson: I've got quite a lot of experience with the CC1125. It's similar to the CC1120, but with increased sensitivity. The CC1200 has the same pinout and registers as well, but the maximum data rate is increased from 200 kb/s to 1 Mb/s (at the cost of reduced sensitivity at similar data rates when compared to the CC1125).

[08:55] <gonzo_> or it';s stuill in the boot of someone's car
[08:55] <daveake> Can we guess what fields those 10 are and make a new payload doc?
[08:55] <UpuWork> well when its part of a flight
[08:55] <UpuWork> I think it locks the payload doc for the duration of the flight
[08:55] <UpuWork> so needs DanielRichman or adamgreig or another to fix it
[08:56] <daveake> ok
[08:56] <fsphil> time and lock seem to be back
[08:57] <gonzo_> suppose at worts they will just lose live tracking till someone hacks a few strings for them
[08:57] <gonzo_> worst

[08:57] <fsphil> ah ha
[08:57] <fsphil> morning pascend-Ross
[08:57] <pascend-Ross> We're lookin good for launch
[08:58] <daveake> no you're not
[08:58] <daveake> Telemetry not uploading
[08:58] <daveake> Payload doc says 11 fields your payload is sending 10
[08:58] <pascend-Ross> yeah, we're putting the electronics in the payload now
[08:58] <Darkside> no, your code is broken
[08:58] <Darkside> either that or your payload doc is broken
[08:59] <pascend-Ross> so its not going to show on spacenear? It was working yesterday
[08:59] <UpuWork> Exception in UKHAS main parse: ValueError: Incorrect number of fields (got 10, expect 11)
[08:59] <UpuWork> $$HAB55331,26,08:55:39,54.667511,-3.350423,88,5,8,24,19,79*B56B
[08:59] <UpuWork> your payload doc is expecting 11 fields
[08:59] <UpuWork> but your transmitting 10
[09:00] <UpuWork> I've requested someone fixes in the database
[09:00] <LeoBodnar> have you tweaked the code last night?
[09:00] <UpuWork> but they may not be availble to do this at short notice
[09:00] <pascend-Ross> right
[09:00] <UpuWork> I think
[09:00] <LeoBodnar> if we know which fieald is missing we can just make anther flight doc
[09:00] <pascend-Ross> its not the code
[09:00] <UpuWork> you added the wrong payload doc
[09:01] <UpuWork> to the flight document
[09:01] <pascend-Ross> we havnt changed anything
[09:01] <pascend-Ross> right
[09:01] <UpuWork> fsphil can you change flight docs ?
[09:01] <pascend-Ross> can we change it quick?
[09:01] <fsphil> I can't sorry
[09:01] <LeoBodnar> make a new one
[09:01] <daveake> Your payload doc is expecting callsign/count/time/lat/long/alt/sats/error/insidetemp/outside/altbypress
[09:01] <daveake> one of those is missing in your code
[09:01] <UpuWork> LeoBodnar its on an approved doc
[09:01] <fsphil> can a new one be approved?
[09:01] <UpuWork> daveake the transmitted data matches the live data
[09:01] <fsphil> it might override the old one
[09:02] <UpuWork> but the flight doc has an old payload doc attached to it
[09:02] <pascend-Ross> on dlfldigi it is showing all of those
[09:02] <LeoBodnar> that's what i think is default behaviour fsphil
[09:02] <daveake> UpuWork, OK, I only saw one of each
[09:02] <UpuWork> I'll try make a new flight doc hang on
[09:02] <Darkside> UpuWork: make sur to label it 'FIXED' o rsomthing
[09:02] <pascend-Ross> thanks
[09:03] <fsphil> we call this ISH time :)
[09:04] <pascend-Ross> how we looking?
[09:04] <UpuWork> keep transmitting
[09:04] <UpuWork> and uploading data pls

[09:06] <UpuWork> dunno if someone wants to check this

[09:09] <UpuWork> if we could unapprove the doc that would work

[09:09] <UpuWork> but no idea how to do that
[09:09] <fsphil> I could have previously edited the doc directly but they put a stop to that :)
[09:10] <daveake> Any chance of changing the payload id on site then we can put in a new payload doc?
[09:10] <UpuWork> yeah if you can rename the payload pascend-Ross we could work with that
[09:10] <gonzo_> does the server check the CRCs?
[09:10] <Darkside> pascend-Ross: change the callsign to HAB55332 :-)
[09:11] <LeoBodnar> both payload docs contain the same number of fields

[09:14] <pascend-Ross> we can't
[09:14] <pascend-Ross> we can track via coords on our offline map if worst comes to it
[09:14] <Darkside> do you hav prediction capability on that?
[09:15] <pascend-Ross> nope
[09:15] <Darkside> then you probably want to change the callsign.
[09:16] <Darkside> surely it cant be that hard to get the arduino out..

[10:18] <fsphil> disappeared when the altitude got to 10km
[10:18] <fsphil> may indicate a buffer bug
[10:18] <adamgreig> in future I recommend testing it works on spacenear.us before the day of the launch

[10:19] <db_g6gzh> thanks adamgreig

[10:20] <daveake> Only kidding :)
[10:20] <adamgreig> though for future reference
[10:20] <adamgreig> if someone had just made a new flight doc and approved it
[10:20] <gonzo_> they WERE staggering
[10:20] <adamgreig> it would take precedence over the old active flight doc

[10:22] <gonzo_> the AMSAT do, sunday first thing is always thin on the ground
[10:22] <gonzo_> the evening bash does tend to get a bit 'untidy'
[10:24] <LeoBodnar> why ascent rate is dropping? He leak?
[10:24] <fsphil> it's entering some choppy air
[10:24] <fsphil> could be slowing it down?
[10:25] <eroomde> yes i suspect so
[10:25] <fsphil> actually looking at the altitude chart, there's a definite slow down
[10:25] <eroomde> there's loads of vertical turbulence in shear layers
[10:25] <eroomde> if it's accompanied by an abrupt change in the over-the-ground velocity vector, it'll probably be that

[10:35] <mikestir_2E0MXS> mostly <25 mW
[10:35] <eroomde> usually the same band/power but higher duty cycle will specirfically forbid airborne where the same, but with a low duty cycle, allowed airborne

[10:40] <pascend-ross> sorry, our hsdr keeps crashing on our netboox, we're switching to our mac....
[10:40] <mikestir_2E0MXS> same here. I suspect I'd get it on the telescopic
[10:40] <G8APZ> pascend-ross you'll need recovery team to have REAL receivers!!
[10:40] <fsphil> pressure altitude lagging behind the gps alt
[10:41] <pascend-ross> we're using sdr, it's fine is it not?
[10:41] <fsphil> it'll be fine
[10:41] <gonzo_> or drifting cal due to temp?
[10:41] <fsphil> gonzo_: ah could be
[10:42] <Geoff-G8DHE> doubt the sensor is qualified for -43!
[10:42] <G8APZ> pascend-ross so long as you have a line of sight to the payload when it is at low altitude you should receive it.
[10:42] <fsphil> pascend-ross: are you in the chase team?
[10:42] <pascend-ross> yeah, we havent set off yet\
[10:42] <gonzo_> sdr is fine if it works. A real rx is nore reliable though
[10:43] <fsphil> pascend-ross: you'll need to be chasing asap :)
[10:43] <daveake> if not sooner
[10:43] <pascend-ross> yeah, just sorting our stuff for the chase car

[10:49] <LeoBodnar> 4m/s ascent...
[10:50] <LeoBodnar> but payload weight is high so will probably burst OK

[11:17] <fsphil> ascent rate is really high now
[11:17] <fsphil> 5.9m/s
[11:18] <fsphil> what's the expected burst altitude? I'll update the predictor
[11:18] <fsphil> I just noticed it's set to 30km
[11:19] <daveake> 35 I think
[11:19] <fsphil> set
[11:19] <fsphil> it won't be far from hadie2
[11:19] <Geoff-G8DHE> Thats more like the prediction

[11:58] <fsphil> bit near a major road Lunar_LanderU
[11:59] <daveake> No, I just sent an email on Monday changing the dates and number of flights
[11:59] <cuddykid> going to be a one man launch and chase job tomorrow, fortunately the wind is low
[11:59] <fsphil> ah, another green line here
[11:59] <daveake> that always goes well :/
[11:59] <fsphil> 9km
[11:59] <daveake> and 2pm launch
[11:59] <daveake> ISH
[11:59] <cuddykid> cool
[11:59] <fsphil> and gone again
[11:59] <cuddykid> i'm aiming for 11:30/12ish
[11:59] <fsphil> weird
[11:59] <daveake> .600 and .650
[11:59] <cuddykid> good stuff
[12:00] <cuddykid> bbl, going to construct this triangular spaceship :)
[12:00] <fsphil> another green
[12:00] <fsphil> 8163m
[12:00] <daveake> you've got nearly 24 hours left what's the rush? :p
[12:00] <fsphil> must be some good conditions today
[12:01] <Rob_m0dts> yes some tropo about with the high pressure hanging about
[12:01] <daveake> chase car on the map
[12:01] <Pascend-Ross> Showing the chase car now!
[12:01] <db_g6gzh> VHF conditions seem up a bit based on my APRS
[12:01] <fsphil> decode at 7876m. definitly below my horizon
[12:01] Action: LazyLeopard expects to lose contact with HAB55... shortly
[12:02] <fsphil> and another at 7628
[12:02] <Rob_m0dts> lunchtime, will try get best last position i can, bbiab
[12:02] <fsphil> really don't expect to get another
[12:02] <daveake> chase car figures are soooo precise :)
[12:02] Action: fsphil gives up predicting things
[12:03] <fsphil> james lane, moor lane, craggs lane
[12:03] <fsphil> half expecting to find a dave lane
[12:03] <craag> He's landing in my lane?? how dare he..
[12:03] <daveake> Helles Barracks
[12:04] <mikestir_2E0MXS> I guess I'll lose this to the pennines soon
[12:04] <G0ATW> River Ure is flowing fast
[12:04] <G8APZ> still have 10dB/n but poor decodes now
[12:05] <fsphil> +50 points if it lands in the Catterick Racecourse. however -2000 points for landing so near the A1
[12:05] <UpuWork> I've been out what was the ascent rat e?
[12:05] <Lunar_LanderU> fsphil: that I meant
[12:05] <Lunar_LanderU> can see it on the map
[12:05] <fsphil> -6.9m/s atm
[12:05] <UpuWork> no I can see that
[12:06] <UpuWork> on the way up
[12:06] <craag> UpuWork: Ascent was about 6.1 average
[12:06] <UpuWork> excellent
[12:06] <fsphil> landing in 20 minutes
[12:06] Action: UpuWork high fives Pascend-Ross
[12:06] <fsphil> still got a trace on the waterfall
[12:07] <mikestir_2E0MXS> what was with that 0 lat/long?
[12:07] <mikestir_2E0MXS> that'll make a mess of the map
[12:07] <fsphil> seems a nice landing area
[12:07] <fsphil> 0,0 won't get plotted
[12:07] <fsphil> does mean it could have lost gps lock though
[12:09] <Andrew_M6GTG> gps jammer at the barracks? ;-)
[12:09] <Geoff-G8DHE> Nope not at Catterick
[12:09] <G8APZ> Congratulations on a good flight to pupils @ Cockermouth School
[12:09] <Pascend-Ross> Does anyone know who is tracking from hull! and thanks!
[12:10] <Geoff-G8DHE> G0ATW
[12:10] <fsphil> Rob_m0dts: you should do pretty good at this
[12:10] <fsphil> eek, going off prediction
[12:11] <Geoff-G8DHE> Last nights prediction has that curve to it
[12:11] <Geoff-G8DHE> just not quite as severe!
[12:12] <fsphil> should still land short of the A1
[12:13] <Pascend-Ross> Okay, we decided to ring the Yorkshire police to let them know that there is something coming down in that area
[12:14] <daveake> plus the predictions assumes 0m altitude on the ground
[12:14] <gonzo_> they will cordon the county off
[12:15] <daveake> It's Yorksire. It already is.
[12:15] <daveake> +h
[12:15] <fsphil> Sandhole Covert -- who names these things!
[12:16] <mikestir_2E0MXS> gone
[12:16] <mikestir_2E0MXS> very abruptly
[12:16] <BalloonYOLO> Launching 13.00
[12:17] <fsphil> Great Pond isn't very great
[12:17] <G6SUQ> there doesn't appear to be too many trees in that area
[12:18] <Geoff-G8DHE> BallooYOLO sounds good
[12:18] <fsphil> BalloonYOLO: did you get a flight doc made up and approved?
[12:18] <BalloonYOLO> Docs up
[12:19] <BalloonYOLO> Not sure if its approved, but our flight is listed on spacenear.us
[12:19] <BalloonYOLO> BALYOLO callsign
[12:19] <G0ATW> Can still hear it but no decode now
[12:19] <fsphil> BalloonYOLO: drop into #habhub and give them the big long ID for the flight document
[12:19] <fsphil> they'll get it approved and it'll be listed in dl-fldigi
[12:20] <Geoff-G8DHE> Thats a manual text entry, without approve its not in dl-fldigi
[12:20] <fsphil> looks like this might land near a caravan park
[12:20] <UpuWork> gone for me
[12:20] <UpuWork> yeah
[12:20] <UpuWork> that was like someone just turned it off :)

[12:27] <Lunar_LanderU> that was great, thanks to REACT for making this possible
[12:27] <pascend-ross_> yeah
[12:27] <REACT> To my knowledge there wasn't a back up tracker?
[12:27] <Lunar_LanderU> pascend-ross_: and my jackpot question is: what was the technical outload of the system, especially sensor-wise?
[12:27] <G8APZ> fsphil - useful to have a backup tracker with an internal antenna in the package so it continues on the ground!

[12:40] <cuddykid> someone picked it up?!
[12:40] <fsphil> yea
[12:40] <fsphil> looks like a farmer has it

[12:41] <fsphil> pascend-ross: it did :)

[12:42] <G8APZ> 01748833665 is belmont farm
[12:42] <REACT> oh Belmont
[12:43] <REACT> Chase car, their number is above. Atleast you know where to go now.
[12:44] <pascend-ross> yea thanks doing now
[12:44] <G8APZ> Not sure... map says Belmont but number is Craggs Farm
[12:45] <cuddykid> brought my stolen and damaged tracker back to life :)
[12:45] <pascend-ross> no answer, its got all the details on it so we're expecting a call soon
[12:45] <gonzo_> they are taking if for a little walk around
[12:46] <pascend-ross> landed on a sheep? :P
[12:46] <LazyLeopard> Hmmm... flickery overlay on dl-fldigi waterfall isn't fall-out from an old config, happens all the time with --hab, and only when the mouse is on the waterfall when not using --hab... It's some cursor-related overlay that doesn't quite work on this system. :/
[12:46] <craag> gonzo_: I wonder how spooked they'll be when shown the map :P
[12:46] <REACT> "We know where you live" kind of thing
[12:46] <pascend-ross> "hello, have you got the package?" XD
[12:47] <cuddykid> I'm tempted to adjust the message on outside of payload for tomorrows flight, make it a bit more scary/do not touch

[13:16] <craag> BalloonYOLO: Lost lock after launch?
[13:16] <craag> I've never understood why people send 0,0 for now lock, would be better to send last known position surely?
[13:17] <craag> (when you have number of satellites to indicate live lock)
[13:17] <Darkside> thats what i do..
[13:17] <daveake> Indeed - I just reject < 4 sats
[13:17] <Joel_re> hmm
[13:17] <Joel_re> daveake: so dont transmit any data with less than 4 sats?
[13:18] <daveake> don't *accept*
[13:18] <daveake> The transmit side would then just transmit the last known good position
[13:18] <Darkside> as in, dont copy the new data into your lat/long variables
[13:18] <daveake> ^
[13:18] <Joel_re> hmm
[13:18] <Joel_re> isnt that upto habonline
[13:19] <daveake> because it's unreliable/bad data
[13:19] <Joel_re> to accept that data or not
[13:19] <Joel_re> apoligies if Im missing out something
[13:19] <daveake> Remember also that Tx takes 15-20 seconds, during which time you'll receive 15-20 GPS positions. You just need 1 good one.
[13:20] <Joel_re> hmm
[13:20] <daveake> So the one I send will be the last good one out of that lot
[13:20] <Joel_re> right
[13:20] <Joel_re> got it

[13:22] <G8APZ> good BALYOLO packets.. no GPS :-(
[13:22] <eroomde> well you can still recover it then
[13:22] <fsphil> no sign of it here
[13:22] <eroomde> we've tracked normal hab flights just with 1Hz beepers on 434
[13:22] <eroomde> just need a yagi and a car
[13:23] <daveake> I should do that sometime
[13:23] <daveake> Maybe a launch after the conf with just a beeper
[13:23] <Geoff-G8DHE> Is it flying or just on the ground ?
[13:23] <daveake> See who finds it first
[13:23] <G8APZ> +20dB/n here
[13:23] <daveake> flying then :)

[13:24] <Joel_re> or just at touchdown
[13:24] <Geoff-G8DHE> must be below 4Kms
[13:24] <G8APZ> constant RTTY - packet 240
[13:24] Action: Joel_re is adding GSM, hoping it will pick up network
[13:24] <Joel_re> quickly*
[13:24] <Joel_re> once its on the ground
[13:24] <fsphil> 50/50 odds of it working, but still useful for a backup

[13:25] <daveake> yes
[13:25] <G8APZ> still no sign of the chase car.....
[13:25] <Joel_re> eroomde: 1Hz, hrm
[13:25] <eroomde> that way we can triangulate it in the air
[13:25] <Joel_re> I read that wrong
[13:25] <fsphil> 1Hz would need a heck of an antenna
[13:25] <G8APZ> better to accept any GPS than to send 0?

[13:26] <fsphil> just have it charge up a capacitor, then enable the ntx2 and drain it
[13:26] <craag> G8APZ: Not really, any non-fix gps will be at least a few miles out, sometimes countries out.
[13:26] <fsphil> repeat
[13:26] <eroomde> the dipole for 1hz would have a length of about...
[13:26] <G8APZ> craag OK
[13:26] <eroomde> 4ish earth circumferences
[13:28] <craag> Given that this is the habduino with an active gps antenna, I'm going to guess they've sheared the gps coax on launch.
[13:28] <craag> Even the antenna upside down should get a fix in the air I think.
[13:28] <Lunar_LanderU> 7.5x earth circumference even

[14:02] <Joel_re> does it increase costs to add a reciever on the HAB?
[14:02] <Joel_re> for e.g to trigger resets
[14:02] <fsphil> depends on the receiver
[14:03] <Geoff-G8DHE> Its going to cost power
[14:03] <Joel_re> hmm
[14:03] <craag> And receiver code will add 100x more complexity than just some automatic resets
[14:03] <mfa298> people have added recievers but as they're usually not that sensitive you usually need a better tx on the ground (which probably needs an amateur license or similar to operate)

[14:04] <cuddykid> good
[14:04] <Joel_re> hmm
[14:04] <eroomde> so you want: 1) some function that decides if you are OK or NOTOK

[14:04] <eroomde> and then something that can reliably re-boot whatever it is as a function of that

[14:07] <mattbrejza> thought so
[14:07] <mattbrejza> do they specify purity?

[14:08] <mattbrejza> ah nice
[14:08] <mattbrejza> also order thru uni and get it cheaper :)
[14:10] <edusupport> No specs on purity
[14:10] <fsphil> I suggested H2 for the school launch, they declined :)
[14:10] <mattbrejza> same
[14:10] <edusupport> Mine too
[14:10] <mattbrejza> however uni H&S doesnt seem to care too much
[14:10] <mattbrejza> which is nice
[14:10] <fsphil> I believe they talked nicely to BOC and got the Helium for nearly free anyway
[14:11] <edusupport> We are trying that route

[16:12] <daveake> Depends how close you are, but typically 500m or so
[16:12] <daveake> That's when the last receiver drops out, roughly
[16:12] <mikestir_2E0MXS> it seems to be getting stronger again here. Where was it launched from?
[16:13] <daveake> Once on the ground you generally need to be within 1-2km

[16:13] <db_g6gzh> Joel_re: I'm only listening to the audio on the RTL-SDR, my decoding is being done with 2 hardware radios on a proper antenna
[16:14] <Joel_re> oh ok
[16:14] <Joel_re> daveake: so at 500m altitude, what distance could the payload crash at
[16:14] <db_g6gzh> I've decoded down to ~250m at 20km before now but the land is flat here
[16:14] <daveake> crash? :/
[16:15] <Joel_re> heh
[16:15] <Joel_re> well touchdown
[16:15] <Andrew_M6GTG> BALYOLO still booming here in Nottinghamshire
[16:15] <daveake> Well it's doing 10mph vertically, so if say the wind was 20mph then that's 1km away from the last position

[16:24] <BalloonYOLO> Thanks - that makes sense; it's at least roughly where we think it is .... :/
[16:24] <Geoff-G8DHE> Joel_re, Many use omni directional aerials and those with beams are a way off so accuracy is VERY low
[16:24] <CHRISG7OGX> do you want me to stay on it?
[16:24] <mikestir_2E0MXS> its clearly still high then because I'm still getting an ok signal up here on an omni
[16:24] <SM5OCI> Sorry for not keeping up with current discussions, but what are the uX{0,1,2,3,5}?
[16:25] <mikestir_2E0MXS> I could go up in the loft and wave my yagi about, but it's not going to be accurate at this range
[16:25] <Geoff-G8DHE> 5 Balloons checking burst height quality
[16:25] <mfa298> Joel_re: with a few people and directional antennas it's possible to get an idea of where it is - but I think most of the people with directional antennas are currently at work so can't get bearings.
[16:25] <BalloonYOLO> any thing would help :)
[16:25] <CHRISG7OGX> ok will stay on it. need zz now but all left in auto

[16:33] <fsphil> the map is a nice visualisation of the wind speed differences at altitude
[16:34] <mfa298> BalloonYOLO: do you have any predictions of what it was supposed to do ?
[16:35] <navrac_work> ux0 coming down?
[16:35] <mattbrejza> seems so
[16:35] <mattbrejza> yep
[16:35] <BalloonYOLO> mfa298 - yes - we were expecting a burst over a hour ago though so all bets are off
[16:37] <mfa298> did you still have the link from it that you can share, that might help anyone trying to determine where it might go.
[16:38] <BalloonYOLO> no I'm afraid not; all predictors are indicating, given the flight time etc and the lower ascent rat, a descent somewhere between Maidstone and Gillingham
[16:39] <BalloonYOLO> I presume we still have a strong signal?
[16:40] <Steve_G0TDJ> Did anyone else get sentence 568 of uX0 as $$$uX0,568,16:39:49,0.00000,0.00000,0,1.37,0,070*D3B6
[16:41] <mikestir_2E0MXS> BalloonYOLO: my bearing is about 135 degrees, but it might not be very good due to local obstructions
[16:41] <mikestir_2E0MXS> combined with Geoff-G8DHE's bearing that would put it somewhere near west london
[16:41] <mikestir_2E0MXS> which sounds a bit far north based on predictions
[16:42] <Geoff-G8DHE> BalloonYOLO, Its now a little East of North for me but lower strength than before.
[16:43] <Geoff-G8DHE> quite a stable signal at present
[16:43] <db_g6gzh> Steve_G0TDJ: yes, 0 lat/lon in that one
[16:44] <Steve_G0TDJ> db_g6gzh: Strange it didn't corrupt the tracker map
[16:44] <db_g6gzh> I think 0 is ignored
[16:44] <Steve_G0TDJ> Ah right
[16:44] <mattbrejza> i would guess theres a no lock flag

[17:56] <Upu> don't know if anyone else has a direction
[17:56] <g0pai_ian_> Just noticed that uX3 isn't too far off the end of the runway at RAF Honnington. Is that stn still active? Bit late for tea in the mess though!
[17:56] <bertrik> and suddenly ux5 is really weak for me
[17:56] <Geoff-G8DHE> I've not played with the elevation as its driven by the uX balloons for elevation at present
[17:57] <Steve_G0TDJ> Lost all here. Just a feint trace of BALYOLO on the waterfall
[17:57] <Geoff-G8DHE> .. estimate its 15 degrees elevation for me

[17:58] <Upu> Geoff-G8DHE can we get an approximate location with that info ?
[17:58] <g0pai_ian_> Read it at the time, but missed the significance . . . a bit slow here at times.
[17:58] <mfa298> Upu with the bearing earlier from Geoff I reckon that could be approaching Canterbury (with very quick guesstimates on the screen)

[19:15] <G8APZ> if only there was a way of kiking the GPS!!

[19:15] <Upu> well sadly there is
[19:15] <Upu> but its not in that branch of code
[19:20] <G8APZ> Upu a piece of code which says if the packet transmitted is the same as the last 10 times.... kick it!!
[19:20] <Upu> that code exists
[19:20] <Upu> and for reason I can't answer is missing in the habduino branch
[19:20] <Upu> though in fairness this is an issue I've not seen in a year and a half
[19:21] <mfa298> question is whether it's a software or hardware failure - although we may never know.

[19:23] <Upu> I know exactly what it is
[19:23] <Upu> I've seen it before
[19:23] <G8APZ> Aargh!!
[19:23] <Upu> if you engage cyclic mode
[19:23] <Upu> and something jams or interferes with the GPS it can lock up
[19:24] <Upu> if you switch it back to max performance on detection of this it normally recovers
[19:24] <Upu> in extreme circumstances the code cold boots the GPS
[19:24] <Upu> but note I've never seen the code trigger on any flight I've done
[19:24] <Upu> you can tell by the status codes

[19:26] <Upu> evening jcoxon
[19:26] <G8APZ> BALYOLO is peaking on bearing 122 from IO93FR bearing from G0RUZ Conrad
[19:27] <Upu> when Geoff-G8DHE is back we can try another bearing
[19:27] <Upu> Oh hi Conrad :)
[19:27] <G8APZ> Upu he isn't here, I was in ON4KST chat
[19:27] <Upu> ah ok
[19:27] <Upu> tell him to come on here :)
[19:27] <Upu> He goes to my club
[19:29] <Upu> we have a rogue balloon up jcoxon
[19:29] <Upu> its not transmitting location information
[19:29] <Upu> and is likely to be in a float
[19:31] <jcoxon> Upu, lost lock? or lost telem and just carrier?
[19:31] <G8APZ> full blocks of telem ... no lat/lon or height
[19:31] <Upu> is habduino code and it went into PSM and did that thing where the GPS chip locked
[19:32] <Upu> for some reason the habduino code is missing the code that catches and resets
[19:32] <jcoxon> eek
[19:32] <G8APZ> Upu Conrad says he's very busy but he'll pop in for a few mins

[19:33] <Conrad_G0RUZ> Oh OK, I'll bookmark the page then
[19:34] <Upu> nps
[19:34] <Upu> cheers for the bearing
[19:34] <Upu> we are trying to triangulate the position
[19:34] <Conrad_G0RUZ> NO chance of that with me I'll be tracking the moon soon, Anthony you really should come down soon
[19:34] <Upu> yeah I know
[19:34] <Upu> I will pop by the club one Thursday
[19:35] <Upu> just been busy of late
[19:35] <Conrad_G0RUZ> Maybe some of the lads at the club would be interested, I will be able to do AZ/EL on 144,432 and 1296

[19:45] <Babs_> Evening chaps - still converting my ublox output into a sensible latitude and longitude and i'm back to the issue of spotting whether there is a negative number or not
[19:46] <Babs_> the ubx punts out 4 hex digits to describe longitude
[19:46] <Babs_> well, 4 in the form XX
[19:46] <G8APZ> still 27dB/n here... strange, it's been strong since it was launched
[19:46] <eroomde> any news from yolo?
[19:47] <Babs_> A leading F in the most significant digit says that I need to multiply the result by -1 as the lat/long is negative
[19:47] <Geoff-G8DHE> Wow just got backup and its still there!
[19:47] <Upu> want to do one of your fancy thing if we give you some directions ?
[19:48] <Babs_> but how do I cope with the fact that the ubx punts out the most significant digit as a pair?
[19:48] <fsphil> Babs_: most significant bit, not digit
[19:48] <Geoff-G8DHE> YUp lets start swining aerials and see whar bearings we get
[19:48] <Babs_> correctomondo fsphil
[19:48] <fsphil> you're thinking in digits not values :)
[19:48] <fsphil> but really if you just put the ublox value into an int32_t, you're done
[19:48] <aadamson> so mask off the MSB and if it's a 1 change the sign
[19:48] <aadamson> yep, that will also work
[19:49] <fsphil> that won't work either
[19:49] <Babs_> so lets say my most significant hex pair is FF, and the rest are AA, BB and CC, is the calc
[19:49] <fsphil> forget pairs
[19:49] <fsphil> forget hex :)
[19:49] <Upu> Geoff-G8DHE 127 from 53.75200, -1.81837
[19:49] <aadamson> think binary
[19:49] <Upu> anyone else want to do a DF for Geoff-G8DHE
[19:49] <mfa298> aadamson: I think that means something very odd is happening for you. I just tested the websdr and it works usb/usb and no rv (as it should be)
[19:50] <aadamson> mfa298, save version of dl-fldigi? might something have changed in the later versions?
[19:50] <Babs_> -1* (256^3 * F +256^2 * AA + 256 * BB + CC?
[19:50] <fsphil> Babs_: so you have an int32_t but in four separate bytes
[19:50] <Babs_> ok
[19:50] <fsphil> you need to store it in a proper int32_t variable
[19:50] <fsphil> the first byte, the one that contains the least significant values
[19:50] <fsphil> just put that in as is
[19:50] <mikestir_2E0MXS> this sounds terribly complicated. I just read the UBX into a buffer and cast it to a struct
[19:50] <G8APZ> GI4SNA in IO64XM gives heading 120 s3
[19:51] <mfa298> aadamson: the 3.21.50 version has been the stable version for years (the later builds have some issues with rtty)
[19:51] <mfa298> https://dl.dropboxusercontent.com/u/14636926/hab/websdr.jpg <- that's what I've got
[19:51] <fsphil> the second byte, you need to shift it up 8 bits before adding it
[19:51] <fsphil> so you'd do something like value += byte[1] << 8;
[19:51] <aadamson> ah... ok, then I have something else messed up.
[19:51] <Babs_> so what is the equivalent calc to my above then fsphil? i don't understand the lingo...
[19:51] <fsphil> then << 16 for the third byte
[19:51] <Geoff-G8DHE> OK I've got 75 degrees East what time was that G8APZ ?
[19:52] <aadamson> mfa298, what mode should I have selected?

[19:52] <aadamson> 50-hab?
[19:52] <fsphil> Babs_: AA * 256 is exactly the same as AA << 8
[19:52] <Geoff-G8DHE> right lets see what those three give
[19:52] <mfa298> aadamson: I used autoconfigure for EAL Test and then adjusted the shift down a bit (to 420)
[19:52] <G8APZ> 19:38 from GI4
[19:52] <Babs_> so -1 * (256^3 * FA + 256^2 * AB + 256 * BC + C?
[19:52] <fsphil> both shift the value up (or to the left to use the proper term) 8 bits
[19:53] <G8APZ> at 19:25 122 from IO93FR
[19:53] <Babs_> sorry, -1 * (256^3 * FA + 256^2 * AB + 256 * BC + C)
[19:53] <fsphil> something like this: int32_t value = AA + (BB << 8) + (CC << 16) + (DD << 24);
[19:53] <fsphil> where AA is the least significant byte
[19:54] <aadamson> mfa298, solved the mystery, seems I had it configured *WRONG* and probably was in 8n1 instead of 7 bit mode...

[19:54] <aadamson> working now, usb/usb...
[19:54] <aadamson> live and learn
[19:54] <mfa298> aadamson: if you can zoom in the websdr waterfall you should be able to see the passband it's using which will help show if the websdr is usb or lsb
[19:54] <Babs_> i don't understand the <<, just trying to understand the math for now
[19:54] <fsphil> Babs_: if you have this 8-bit value: 00001111
[19:54] <fsphil> and you shifted it << 2 bits
[19:54] <mfa298> aadamson: was that fixed just by using autoconfigure ?
[19:54] <fsphil> you'd end up with 00111100
[19:54] <fsphil> it just simply moves all the bits to the left
[19:55] <eroomde> which is the same as x2
[19:55] <eroomde> in unsigned binary land
[19:55] <Babs_> but my formula above holds then right?
[19:55] <Babs_> as two bits to the left is *16^2
[19:55] <aadamson> yes mfa298
[19:55] <Babs_> once i get the maths correct, i will move onto getting it coded like you pros
[19:55] <fsphil> I'm not certain it would work for negative signed values
[19:56] <fsphil> I'll test
[19:56] <aadamson> mfa298, is that just a birdy down at 434.494?
[19:56] <fsphil> weirdly this would be much easier to explain in a drawing
[19:56] <G8APZ> G4KUX in IO94BP has heading 180
[19:58] <mfa298> aadamson: looking at the earlier screenshots it may just be that the signal and settings weren't quite there - the "copy" version doesn't look like it's actually got any balloon decode just random chars.
[19:59] <aadamson> yeah I think the default for rtty is 8bit is part of the problem
[19:59] <aadamson> and most likely that's how it was setup until I did the autoconfigure
[19:59] <fsphil> Babs_: hah, does work
[19:59] <aadamson> long path to get there, but did help sort out a couple of other things
[19:59] <Geoff-G8DHE> http://360.g8dhe.net/HAB_Flights/2014_Flights/EAL_TEST_FLIGHT_2_20140312/fic1950.jpg I missed out the 180 degree one
[20:00] <CHRISG7OGX> egg on chin here had to sit son in front of screen and i turned beam...nothing!!! so prob this end sorry. good sigs still on omni
[20:00] <Geoff-G8DHE> this looks sort of expected maybe making landfall in Belguim ?
[20:00] <Babs_> finally, on 18 years after it was earned, my maths degree comes in useful in adult life. thanks fsphil
[20:00] <mfa298> if there's a flight doc for the flight it's always worth doing autoconfigure - or make sure all the settings are right (most people use 7 bit unless there's ssdv)
[20:00] <fsphil> Babs_: I'll put some comments into this little test program and send you it. might help you visualise it
[20:01] <Geoff-G8DHE> None of the Dutch lads about ?
[20:01] <aadamson> mfa298, yeah there wasn't one for Balyolo so I wasn't sure
[20:01] <Babs_> that would be awesome - thanks fsphil. i think i can see where you are coming from with your code, i am just trying to build up bit by bit (no pun intended)
[20:01] <fsphil> pun accepted
[20:01] <Reb-SM3ULC> Evening

[20:01] <bertrik> Geoff-G8DHE: hm, anything I can do?
[20:02] <mfa298> aadamson: EAL TEST Flight was their last flight (I think) so seemed like a good starting point.
[20:02] <aadamson> mfa298, oh, got it... sounds reasonable

[20:02] <Geoff-G8DHE> Tks f5apv I'll add that one in
[20:03] <Babs_> so if my consecutive bytes are ZX YV UT SR where Z is the most significant digit, then (I think) the following works. Test to see whether the Z is a hex F
[20:04] <Babs_> if it is then the number is -1*(XY * 256^3 + VU * 256^2 + TS * 256 + R
[20:04] <bertrik> I'm getting BALYOLO really strong, 27 dB
[20:04] <Geoff-G8DHE> bertrik, Thats OK then no chasing needed we are just triangulating it as the GPS failed
[20:04] <fsphil> what frequency is it on?
[20:04] <Babs_> if it isn't then the number is ZX*256^3 + YV*256^2 + UT * 256 + SR

[20:06] <aadamson> Babs_, you need to think in binary... not sure how the protocol works, but 0xff is 0b11111111 so if it's the MSB (most significant bit) that is set, you can't look at the "F" part,
[20:06] <aadamson> 0x10111111 != 0xff
[20:06] <aadamson> for example
[20:07] <mikestir_2E0MXS> Babs_: are you getting it out of the GPS in hex? I thought it just came over in binary?

[20:07] <aadamson> again, I don't know the protocol...
[20:08] <aadamson> but if it's the first bit, you'd need to mask it off to determine if it's set or not - just that bit
[20:08] <aadamson> then deal with the values as fsphil mentioned by shifting them into a int32_t or some such

[20:14] <Geoff-G8DHE> Didn't see a write up of what they used :-(
[20:14] <LeoBodnar> say if your single byte =0xFF it is actually = -1
[20:14] <Upu> however the wind data is 6 hours old at any given time

[20:17] <Upu> maybe not
[20:17] <Babs_> my simple code works for positive values, i'm looking for a simple logical way i can get the same results by performing some simple logical operations to test for negative values. if [digit] is [something] then [treat it differently] kind of thing
[20:17] <eroomde> Babs_: given your maths bg, and pretending there aren't forthcoming big changes to your life, you might enjoy doing SICP
[20:18] <Babs_> evening eroomde - i just started a new job too.
[20:18] <Babs_> eroomde, did you see my formulae up there ^^
[20:18] <amell> any ssdv today?

[20:19] <eroomde> i didn't see the forumla
[20:19] <Babs_> yes, they are an excellent firm
[20:19] <PE2G> I'll put the yagi back up
[20:19] <eroomde> is it still in PE?
[20:19] <Geoff-G8DHE> OK Chris that would be very similar to mine then, lets add that in
[20:19] <DutchMillbt> Good idea PE2G
[20:19] <Babs_> if my consecutive bytes that the ubx punts out (it knocks out 4 bytes to enable me to generate a latitude), and those bytes are ZX YV UT SR where Z is the most significant digit, then (I think) the following works. Test to see whether the Z is a hex F
[20:19] <aadamson> Babs_, for example, let's say that the data is structured as the first 2 bytes are int, second 4 are long etc... you could have a structure of one int and one long and read those 6 bytes in and use the values out of the structure instead of all the math conversions.... but you run a risk there if the bytes are returned in a format different from platform to platform this is called endianness

[20:22] <Upu> a number of stations have taken bearings from the strongest signal
[20:22] <Babs_> still want to understand the maths...
[20:22] <Babs_> thanks everyone
[20:22] <amell> yeah, which one is it? what is call sign of this loon?
[20:22] <mfa298> aadamson: it needs to be fairly high up for the people who are getting it to all receive it (around 30km high or more)
[20:23] <Upu> it doesn't have one
[20:23] <Andrew_M6GTG> Still got steady strong signal, NE (45 degrees) from here in Newark IO93OB, much more distinct max
[20:23] <Upu> fsphil can you rx this balloon ?
[20:23] <aadamson> it's how no frequency shift since this morning, it's been dead nutz on 434.5000 +/- only a smidge
[20:23] <chrisg7ogx> nice cocked hat
[20:23] <amell> so is this a macdonalds happy meal balloon? How can it not have a callsign
[20:23] <aadamson> mfa298, yeah that would make sense... given the plots I just saw

[20:26] <aadamson> well bummer, there goes the websdr, do you guys have radar or a neon light around it that would have kick on about 30 seconds ago?
[20:27] <G8APZ> steady signal for past 7 hours in JO01do .... it cannot be on the ground and heard in GI, G, PE, ON
[20:27] <Upu> sure its floating up there somewhere
[20:27] <mikestir_2E0MXS> maybe it landed on a circling AWACS

[20:28] <fsphil> I've a potential signal on 434501060+1504
[20:28] <fsphil> 470hz shift
[20:28] <Geoff-G8DHE> No I didn't what bearing was it Andrew_M6GTG ?
[20:29] <Geoff-G8DHE> Oh NE/E ?
[20:29] <Andrew_M6GTG> max around NE
[20:29] <Andrew_M6GTG> 45 degrees
[20:29] <fsphil> the potenatial signal has given me a few $$'s
[20:30] <amell> trying to figure out how to connect dl-fldigi direct to radui
[20:30] <mfa298> amell: some people have used it on the mac but I think it's a bit of an effort making it work unless theres a pre-compiled binary that works for you.
[20:30] <Geoff-G8DHE> Eeek could that be a side lob like my first attempt after tea ?
[20:30] <amell> radio
[20:30] <eroomde> in the asteroid belt, the average distance between objects of the order of 1km across and greater is about 2 million miles
[20:30] <chrisg7ogx> when i was younger i had side lobes!
[20:31] <Geoff-G8DHE> I think we leave it at this point and see what happens to the signal strength! that seems very odd as well!
[20:31] <G8APZ> incredibly stable....
[20:31] <MoALTz_> so around 10 light seconds
[20:31] <fsphil> lots of commas, numbers and $$'s decoding
[20:31] <fsphil> so this does look like it
[20:32] <Geoff-G8DHE> SP9UOB isn't flying around in his light plane is he ?
[20:32] <fsphil> can someone else tell me the exact shift?
[20:32] <Lunar_Lander> so you think balloonyolo started to float and crossed the channel?
[20:32] <G8APZ> 7 hours of stable sigs.... and not a lat/long to be seen...incredible!!
[20:32] <fsphil> I've worked it out to about 440hz
[20:32] <chrisg7ogx> crossing south of north sea
[20:32] <Lunar_Lander> hmm
[20:32] <Geoff-G8DHE> I get 450 Shift
[20:32] <Lunar_Lander> wonder if it could be triangulated?
[20:32] <fsphil> that's close enough
[20:32] <LeoBodnar> dl-fldigi on a Mac here
[20:32] <G8APZ> Shift 450
[20:32] <LeoBodnar> also jcoxon i think
[20:33] <x-f> and me too
[20:33] <Lunar_Lander> if there are three people with directional antennas
[20:33] <fsphil> it's very slowly dropping in frequency?

[20:35] <mikestir_2E0MXS> how long is the battery expected to last?
[20:35] <G8APZ> balyolo has an SMS that works below 1000ft
[20:35] <SIbot1> In real units: 1000 ft = 305 m
[20:35] <aadamson> I just wonder if any heigh would give you a path in that direction?
[20:35] <Geoff-G8DHE> I think so but it might be a bit wet and out of range if it ever lands ;-)
[20:35] <G8APZ> that works below 305m!!
[20:35] <x-f> 1000 meters?
[20:35] <amell> slbot1: you're very annoying.

[20:37] <BALYOLO_> YOLO GSM kicks in at 1000m - we had a text from March Cambridgeshire around 1800 but only the one - it ties in with the fixes I've seen, but from what everyone is saying YOLO is still flying
[20:37] <chrisg7ogx> just had to tweak beam slightly more towards the NE
[20:37] <Andrew_M6GTG> amell: Saw the schoolkids on the local news (well Cumbrian news, you have to love Freesat) they were chuffed with their balloon.. no mention of us trackers mind ;-)
[20:38] <amell> balyolo_: are you expecting it to text again? is it set to text at what frequency?
[20:38] <Upu> Hey BALYOLO_ 1200g balloon ?
[20:39] <G8APZ> BALYOLO still 21dB/n here in Essex
[20:39] <fsphil> I'm seeing a signal but I can't verify what it is
[20:39] <f5apq> Yolo signal down abt 350 from 50.855,1.946
[20:39] <G8APZ> packet 2350 just sent out!!
[20:39] <BALYOLO_> I hope so - it should repeat every couple of minutes once it has s decent fix on a mobile tower, which is why the one text we got was a bit strange.l And it was only a 600g balloon - we have no idea why it is still flying!
[20:39] <G8APZ> 434.502
[20:40] <bertrik> 27-30 dB S/N here at revspace, the hague, netherlands

[20:40] <eroomde> are you sure it's still flying?
[20:40] <Upu> well everyone is recieving it
[20:40] <G8APZ> of course it is still in the air

[20:41] <BALYOLO_> If it had descended we would be being bombarded with texts telling us the location - we are flying two GSM transmitters so once we hit 1000m .... we should start hearing them
[20:41] <Upu> I've never seen a 600g float what was the payload weight and initial ascent rate ?
[20:41] <eroomde> i've got 200-300km received on balloons, super clear when they're only a few tens of meters agl
[20:41] <fsphil> if it lands somewhere with mobile coverage
[20:42] <amell> oh was balyolo launched from els worth?
[20:42] <daveake> I hope the SIM cards have roaming enabled
[20:42] <Upu> its too strong to be on the deck Ed
[20:42] <Upu> its really strong here
[20:42] <mfa298> BALYOLO_: GSM at height is a bit more tricky, the base stations probably don't beam that high, and if you're too high and cover too many base stations they might ignore you.
[20:42] <Geoff-G8DHE> No pi marker on last update show launch
[20:42] <BALYOLO_> fsphil - good point
[20:42] <Geoff-G8DHE> PIN marker
[20:42] <BALYOLO_> ascent rate approx 2.5 - 3.0 m per second
[20:42] <BALYOLO_> payload weight 1.2 kg
[20:43] <eroomde> do you have a yagi BALYOLO_ ?
[20:43] <fsphil> that ascent rate is floaty
[20:43] <Upu> 600g with 1.2kg on it

[20:50] <eroomde> last night people were saying 70cm was wide open
[20:50] <Geoff-G8DHE> Quite possible
[20:50] <eroomde> it really does seem odd to me that it could be floating
[20:50] <BALYOLO_> If it is over Norfolk it's taken some bizarre flight path
[20:51] <PE2BZ> I am at JO21CX and my strongest direction was 270 degrees.
[20:51] <eroomde> especially if it got a gsm back from cambridge earlier
[20:51] <Upu> I would concur with that
[20:51] <Geoff-G8DHE> OK PE2BZ one minute
[20:51] <aadamson> if there was a single sms from it in the location noted above, isn't that sorta in the middle of DF'd location?
[20:51] <eroomde> BALYOLO_: assuming you can spare them tomorrow, i'd send them to cambridgeshire with a yagi (directional) antenna
[20:51] <G8APZ> it could be floating for more time than the battery has left!

[20:54] <chrisg7ogx> that is a nice set of cuts
[20:54] <BALYOLO_> if 1800 was the dsecent time it would have been a 4 hour flight which is feasible - but still a weird ground track given the predictions and other flights from that area today
[20:55] <Lunar_Lander> wonder if you can triangulate the altitude as well if you take the elevations
[20:55] <Lunar_Lander> maybe not as easy
[20:55] <eroomde> i guestimated somewhere near ipswich, just eyeballing the winds
[20:55] <Geoff-G8DHE> Most vertical beamwidths are much wider as well
[20:56] <Lunar_Lander> yea
[20:56] <Lunar_Lander> I would agree with ed
[20:56] <Lunar_Lander> when you compare it to the balloon fleet for example
[20:56] <Upu> I mailed Steve
[20:56] <chrisg7ogx> android app EsSence says bands vhf/uhf closed
[20:57] <amell> what was the frequency again?
[20:57] <Upu> 434.500
[20:57] <aadamson> and I guess the obvious is if anyone up in that cambridge/ipswich area might have a vertical that they could give you a signal report from, if it was really strong that might tell you something
[20:57] <PE2G> Geoff-G8DHE: I have it at ~250 deg from JO32HI
[20:57] <Geoff-G8DHE> OK PE2G I'll add that
[20:57] <aadamson> time for a pool! :)...
[20:58] <eroomde> as people have said, steve is well place but probably pegged trying to recovery his 5 launches today
[20:58] <chrisg7ogx> geoff give a time for us all to take bearings then five min later, call them in?
[20:59] <eroomde> have these numbers been changing for anyone? or does it seems fairly static?
[20:59] <aadamson> BALYOLO_, do you have the exact coords from the sms at 1800?

[21:00] <aadamson> eroomde, there has been a recent very slight shift, but it's been dead nuts 434.500 all day, this recent shift could be battery decay related
[21:00] <BALYOLO_> Fraid not - Ben has them and he has gone off radar
[21:01] <eroomde> i been in terms of a bearing to the signal
[21:01] <eroomde> i.e. is the balloon staying still over the ground or moving?

[21:02] <chrisg7ogx> i reckon my beam is at least + or - 15 degrees

[21:14] <db_g6gzh> and I can just hear it on the RTL-SDR using the supplied mag mount so based on how I was receiving Steve's flotilla on that I would say it must be within 40-50km of me if at altitude
[21:14] <db_g6gzh> unfortunately I don't have a beam

[21:15] <eroomde> ok. march was where it reported a gsm lock
[21:15] <amell> trying to feed gqrx into fldigi.
[21:15] <eroomde> it might actually be really close to you
[21:15] <aadamson> yes, any chance you have handheld that you could try to hear it on?
[21:16] <eroomde> without anything difrection it's going to be pretty difficult
[21:16] <PE2BZ> Now I am starting with wild guesses: What's the average height of a drilling platform, or offshore rig and are there any nearby the location of the crossing lines ?
[21:16] <mfa298> amell: if its mac try looking for soundcloud (I think that's the app) it gives you a virtual sound card you can use to pipe audio from one app to another
[21:17] <aadamson> http://www.funker530.com/landing-a-helicopter-on-the-rough-seas/ - dang how do they do it... note the rotor go negative as soon as he's on the deck! :)
[21:18] <eroomde> PE2BZ: nothing much in cambridgeshire/suffolk
[21:18] <eroomde> no real hills
[21:18] <eroomde> some wind farms
[21:18] <Geoff-G8DHE> I'm quite close to the South Downs and if the signal is below 3 degrees I get nothing at all, any mast in East Anglia is way below my horizon
[21:18] <eroomde> suspect we'd hear the doppler tho ;)
[21:18] <amell> mfa298: got that (soundflower) and fldigi still isn't 'hearing' it
[21:20] <G8APZ> if the payload is in a mast , buliding, tree etc... then it would be in ET mode and phone home (assuming there was a phone cell near!
[21:20] <eroomde> i guess those who can take bearings should re-take them periodically
[21:20] <bertrik> I'll leave my receiver on for about two more hours and I'll check in about 8 hours after that
[21:20] <eroomde> and see if it's moving
[21:20] <aadamson> fyi, the chatter on the websdr chat is that the uhf bands are pretty open tonight in your neck of the woods..
[21:20] <G8APZ> still 21dB/n here in Brentwood, Essex Jo01do
[21:22] <chrisg7ogx> losing signals here
[21:24] <aadamson> ah figured out the interference on the websdr, seems you have a net or something going on a local repeater, if you switch it to AM while on 434.500, you can hear the audio
[21:24] <aadamson> and the courtesy tone, etc
[21:24] <mattbrejza> any ideas on where balyolo currently is?
[21:24] <bertrik> a little less strong here now (revspace, the hague, netherlands)
[21:24] <Geoff-G8DHE> In the air ;-)
[21:25] <mattbrejza> yea i can hear it :P
[21:25] <mattbrejza> bit weaker now

[21:25] <PE2BZ> I agree to the weaker signal too. Little down from The Hague. Seems to shift down a little in frequency also
[21:25] <eroomde> maybe it developed a very slow leak
[21:25] <mattbrejza> ah nice
[21:25] <bertrik> from 27 db s/n down to 23 db or so now
[21:26] <mattbrejza> it doesnt seem to have traveled as fast as over launches today if its only just over the channel
[21:26] <mfa298> mattbrejza: you need to get a yagi and rotator up on astra.
[21:26] <Geoff-G8DHE> Yup dropping here as well 10-13db/n
[21:26] <eroomde> yeah, it's slowness is what i find surprising
[21:26] <mattbrejza> that would be good, but i dont think ther eis any need
[21:26] <eroomde> if it was up near the jetstream it should be long-gone over europe by now
[21:27] <mfa298> would be useful for this sort of scenario to get an extra bearing - although doing that remotely might be more interesting.
[21:27] <Geoff-G8DHE> Jetstream is slow today http://www.netweather.tv/index.cgi?action=jetstream;sess=
[21:27] <mattbrejza> it must be a <20km float then?
[21:28] <mattbrejza> or ~20km
[21:28] <mattbrejza> steves ones seem to shoot off at about 21km
[21:28] <G8APZ> At 20:55 G8HGN (JO01FO) Bob said "I can hear the RTTY signal peaking at 003 degrees from here. Unless it's south of me."
[21:28] <DL7AD> good evening
[21:29] <aadamson> still a 15-19db on the websdr - net finally ended
[21:29] <G8APZ> still 25dB/n here in JO01do Brentwood Essex

[21:31] <Geoff-G8DHE> yes fading here slowly
[21:32] <db_g6gzh> projecting Steve's initial low altitude tracks back from near me would continue to near Oxford, so if it never got to higher altitude it could have slowly drifted up this way
[21:32] <chrisg7ogx> nothing on my white stick
[21:32] <aadamson> battery expectation was 12hrs ?
[21:32] <aadamson> could the fade be battery related?
[21:33] <Upu> yes possibly more
[21:33] <Upu> unlikely its a step up
[21:33] <aadamson> so either or nothing...
[21:33] <chrisg7ogx> definite drop in sig strength here
[21:33] <Upu> I don't know what state the GPS is in or how much power its pulling
[21:33] <db_g6gzh> it's just such a steady signal here, almost no fading
[21:34] <db_g6gzh> I think they've snagged a skyhook
[21:34] <aadamson> it's probably just hung up in a tall tree.. out of cell coverage :) happily beaconing away and y'all can hear it :)
[21:35] <aadamson> no fade, not doppler, nothing, if it's in the air, it's in the stillest/calmest air I've ever seen, with no rotation on the *package* etc..

[21:58] <Upu> did you press autoconfigure ?
[21:59] <amell> yes, but I will confess that this is a recording, not actual live radui
[21:59] <Upu> ah
[21:59] <Upu> still auto configure should set the RTTY mode to 50 baud
[21:59] <Upu> with a shift of about 450
[21:59] <amell> somehow i should be able to adjust the two red lines to align

[22:00] <Upu> 434.500
[22:01] <Upu> shift has come down
[22:01] <Upu> which means one thing
[22:01] <Upu> its cold

[22:02] <Geoff-G8DHE> I think ed may have been right ducting about ..
[22:02] <fsphil> steve's launches went north until they got to about 20km wasn't it?
[22:03] <fsphil> well, slowly north east
[22:03] <fsphil> so it could be a low altitude float
[22:03] <Upu> and if you can't get it
[22:03] <Upu> 10km ?
[22:03] <Upu> winds at 10km are very slow northerly
[22:03] <fsphil> how far south are people receiving it?
[22:04] <Upu> Netherlands I think
[22:04] <db_g6gzh> I can't hear it on the indoor mag mount any more but it was only just there before so wouldn't have taken much drop in signal to disappear.
[22:04] <PE2G> Decoding becomes difficult from the east of the NL
[22:04] <PE2G> Losing it.
[22:05] <fsphil> I would guess around 15/16km
[22:05] <fsphil> if it is going that way Brian should hear it within a few hours, if the batteries last
[22:06] <Geoff-G8DHE> What height are you at Upu
[22:06] <G8APZ> I'm hearing it at Brentwood Essex. 21-23 dB/n still

[22:07] <fsphil> it can't be much lower than 15km

[22:14] <LeoBodnar> thanks aadamson, I am doing non-HAB design based on a newer generation of Semtech, but typically their frequency resolution is worse than Silabs'
[22:14] <aadamson> yes, saw that as well
[22:14] <PE2G> I lost BALYOLO completely, no traces anyore.
[22:14] <aadamson> hoperf has an rm69 that uses that chip
[22:14] <aadamson> the ti ones are much more interesting actually
[22:14] <LeoBodnar> I have a thing about TI RF stuff...
[22:15] <aadamson> hehe
[22:15] <aadamson> do tell
[22:15] <aadamson> it's a company they bought chipcon or some such?
[22:15] <mattbrejza> balyolo very weak in soton
[22:15] <mattbrejza> and fading to almost gone
[22:15] <LeoBodnar> Well I have a design based around one of their BT LE chips and they force you to use KEIL compiler for 8051 part of it
[22:15] <aadamson> that's not nice...
[22:16] <aadamson> that must be one of the integrated chips like the cc430
[22:16] <aadamson> etc?
[22:16] <LeoBodnar> the have proprietary compiled binary for BT stuff that only assembles under KEIL
[22:16] <aadamson> so much for open standards :)
[22:16] <LeoBodnar> yeah
[22:16] <mattbrejza> wait for the msp430 radio soc version :)
[22:17] <LeoBodnar> mattbrejza used CCxxx i think
[22:17] <LeoBodnar> so did Laurenceb
[22:17] <LeoBodnar> since then i have developed massive grudge against TI RF products
[22:17] <aadamson> there is a cc1xx that is just a radio chip, and then there is an msp430 integrated version
[22:17] <mattbrejza> cc430 is msp430 + cc1101, but thers is a 8051 + cc1101 (dont know the name), so pershaps theyll be a msp430 + BT
[22:18] <mattbrejza> but the cc430 rf bit is a bit horrible, the cc1101 registers arnt part of the msp430 memory map

[23:18] <fsphil> hah
[23:18] <fsphil> Babs_: I never got my diagram finished, sorry
[23:18] <Babs_> still got it
[23:18] <Babs_> fsphil - no worries
[23:18] <RocketBoy> uX2 was weird too
[23:18] <Babs_> but if you do i think you still have my email?
[23:18] <RocketBoy> a day of weird flights
[23:19] <fsphil> Babs_: I do, I'll throw it over when it's done
[23:19] <Babs_> cool - thanks fsphil
[23:20] <G8APZ> I've had enough of HABS for one day!! May be back tomorrow... but wife wants a visit to tip... it will probably be when the balloons all launch!!
[23:20] <G8APZ> Night all....
[23:20] <fsphil> g'nite!
[23:20] <pascend-ross> How long does the route track stay on spacenear? Night!
[23:20] <G8APZ> ===============================
[23:21] <fsphil> until someone clears it pascend-ross - it's done manually
[23:21] <fsphil> usually before the next flights occur
[23:21] <Geoff-G8DHE> You can grab copies of the flight data from the database anytime in the future, also copies on my image pages
[23:21] <fsphil> now would be the time to grap some screenshots if you want
[23:21] <G8APZ> pascend-ross I may have some screen shots.... please email me at >>> g8apz@g8apz.org.uk
[23:21] <pascend-ross> ahh roge, will do!
[23:21] <fsphil> planning any more pascend-ross?
[23:22] <Geoff-G8DHE> pascend-ross, See this page http://habitat.habhub.org/ept/ it will supply it all in various formats
[23:23] <pascend-ross> I defintely want to do more and I think a lot of the others are...just gotta get our gcses out the way! And thanks, that looks great. The other team that react sponsored is launching tomorrow also.
[23:24] <pascend-ross> think I need english...*definitely
[23:24] <fsphil> hehe
[23:24] <fsphil> I noticed two other notams near you
[23:24] <Geoff-G8DHE> Are they planning onusing snus there are no documents in place ?
[23:25] <amell> APJHAB really lake malawi?
[23:26] <pascend-ross> yeah, they are using off the shelf solutions for everything I believe
[23:26] <fsphil> aww no radio tracker
[23:26] <Geoff-G8DHE> OK, as several others are flying tomorrow as well!
[23:26] <amell> i only see two?
[23:26] <fsphil> it was nice tracking something quite nearby for once
[23:27] <pascend-ross> They will loose signal quite soon after launch will they not? :/
[23:27] <fsphil> depends on what they're using -- but very likely
[23:27] <fsphil> some of the higher power 869mhz modules with a good antenna may work at a fair distance
[23:28] cuddykid (~acudworth@81.170.46.40) left irc: Quit: cuddykid
[23:28] <Geoff-G8DHE> Right I'm off AFK
[23:28] <G8APZ> best use a network of trackers ... too much for a team to track it's own flight and chase it
[23:29] <fsphil> yea. the distributed tracking network is the best thing ever
[23:29] <fsphil> that and the predictor
[23:29] <G8APZ> amateur radio has a pretty wide spread of stations with the tracking capability
[23:29] <amell> rocketboy: did you retrieve all your payloads?
[23:30] <G8APZ> fsphil not forgetting the flDigi HAB and chase applications etc etc!!
[23:31] <fsphil> I'm including that in the first one :)
[23:31] <G8APZ> LOL
[23:31] <G8APZ> I'm really off now GN 73
[23:31] <fsphil> I do like to moan about fldigi but it's really handy
[23:31] <fsphil> nite!
[23:32] <G8APZ> >>>> shuts the door behind him
[23:32] G8APZ (4f4e7330@gateway/web/freenode/ip.79.78.115.48) left irc: Quit: Page closed
[23:34] <pascend-ross> this is also some early access footage of some stuff we found skipping over quickly! Please refrain from sharing for the time being, it's link only and it's not finished haha but take a look!....https://www.youtube.com/watch?v=w4rX1f9Q-no&feature=youtu.be
[23:35] <RocketBoy> amell: some of them - but it was getting dark - so going back for the others tomorrow
[23:35] <RocketBoy> its not far
[23:35] <fsphil> lol, premature countdown
[23:35] <fsphil> I had that at the bbc launch
[23:36] <fsphil> what cameras where these pascend-ross?
[23:36] <pascend-ross> gopro hero 3 white + drift hd standard
[23:36] <fsphil> oh nice you got the isle of man
[23:37] myself (~myself@ignignokt.mudkips.net) left irc: Read error: Operation timed out
[23:37] myself (~myself@ignignokt.mudkips.net) joined #highaltitude.
[23:37] <pascend-ross> that hair that somehow got taped is really iritating me :P
[23:37] <fsphil> I've never managed to get a picture of that from a flight
[23:37] <fsphil> I didn't noticed it until you said :p
[23:37] <amell> Rocketboy: hoped to come and help today, but timing didn't work.
[23:38] <RocketBoy> ah - sure I should have let you know - it was all manic
[23:38] <amell> i can imagine. I was in reading anyway.
[23:39] <pascend-ross> looks like you'll be getting your chute back too steve! :)
[23:39] <RocketBoy> the CAA didn't send the permit through yesterday
[23:39] <RocketBoy> :-) :-)
[23:39] <RocketBoy> so when I didn't get the permit I stopped prepping
[23:40] <amell> Elsworth is like 15 min walk from here.
[23:40] <RocketBoy> then the permit came through this morning
[23:40] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) left irc: Quit: Leaving
[23:40] <RocketBoy> so I had to finsh the payloads and pack the van ....
[23:40] <RocketBoy> so launch was way later than I wanted
[23:41] <amell> have the fields dried up now? they were like a rice paddy a couple of weeks ago
[23:41] <RocketBoy> not too bad - just a few wet patches here and there
[23:42] <RocketBoy> quite a nice day
[23:42] <amell> cool. next time.
[23:42] <RocketBoy> but very hectic - which is when I tend to forget things
[23:42] <RocketBoy> also forgot the sides of the gazebo
[23:43] <RocketBoy> so the idea to fill in a tent was out the window
[23:43] <RocketBoy> but managed to get by - I think I got pretty close on fill
[23:43] BALYOLO (568d47d1@gateway/web/freenode/ip.86.141.71.209) joined #highaltitude.
[23:45] <RocketBoy> yo BALYOLO - any news on the flight?
[23:47] <BALYOLO> nothing yet - not sur eif people are still tracking it?
[23:47] <BALYOLO> excuse typing - tired
[23:47] <RocketBoy> 11:14 Upu said - batteries died I think
[23:48] <amell> we were wondering if you had a SMS yet. apparently not.
[23:49] <BALYOLO> well possibly - but Ben and Sammy have the phone which will receive any texts once we hit 1000m so I am in the dark
[23:50] PE2G (Miranda@a83-161-208-176.adsl.xs4all.nl) left #highaltitude.
[23:50] <BALYOLO> If we don't it's a pity as I would like to see its' crazy flight path ...
[23:51] <amell> Did you activate roaming on the SIM?
[23:52] <BALYOLO> I believe so
[23:52] <RocketBoy> nights
