[00:03] <navrac> nigeys are you a one or two balloner?
[00:03] <NigeyS> 2
[00:03] <NigeyS> wont get 1 with these pcbs
[00:03] <navrac> any idea of weight?
[00:04] <NigeyS> uninsulated, 60gms so abround 65grams
[00:04] <NigeyS> around*
[00:04] <navrac> i reckon then you should be looking at 6-7km not 5
[00:05] <navrac> and a descent rate of o.2m/s
[00:05] <NigeyS> ive put 5 in as conservative, ive had, 4km, and over 7km before now with 4 so ..
[00:06] <NigeyS> http://habhub.org/predict/#!/uuid=399873956c36ee44300d669cfd03e520f45106df
[00:06] <NigeyS> with 0.2m/s descent & 6km burst
[00:06] <navrac> yep but if you choose 6500 and 0.2 you make france!
[00:06] <NigeyS> lol thats the whole idea of waiting for these winds, and the particular launch site
[00:07] <NigeyS> also clear los for tracking
[00:08] <navrac> good luck ill have the radio on, its a bit far for a pico - but i'll try
[00:08] <NigeyS> tnx dude
[00:08] <navrac> just have to hope sharp goes up on time this time
[00:10] <NigeyS> fingers crossed

[05:59] <Upu> well actually what happened was the government got a bit of a scandal
[05:59] <Upu> and as they do when there is some news they don't like they do something to take the attention off themselves
[05:59] <Upu> i.e increase the terror threat is a good one

[09:21] <Udin_SHARP> not entirely sure
[09:22] <daveake> I guess it is. His flight will be up for several hours, probably
[09:23] <jonsowman> SHARP have until 3pm to be finished
[09:23] <jonsowman> then Pico is being launched
[09:23] <jonsowman> aiui
[09:23] <gonzo_> the clash with the cardiff launch going to cause problems?
[09:24] <gonzo_> ok, answered!
[09:24] <gonzo_> (the problems of chat vis VNC, the updates are so slow to scroll up!)

[10:01] <Darkside> and you also managed to wotk out the problem switching from RX to TX mode or osmething
[10:01] <navrac> I used the rf22 library
[10:01] <Darkside> ok
[10:01] <navrac> ah - i only fixed that for the rfm22 library so you will need to do some checking.

[10:02] <eroomde> well there are lots really
[10:03] <navrac> I put a copy there
[10:03] <navrac> ok pm me the email and ill pop it in an email
[10:07] <navrac> the code was on the laptop - so found it on pastebin. If you have time to add a saw filter its worth it
[10:07] <Darkside> hmm
[10:07] <Darkside> i was planning on running on 431.650MHz
[10:07] <Darkside> not 434MHz
[10:08] <navrac> oh welcome to the world of 'cant get saw filter at that frequency apart from one supplier who wont do samples'
[10:08] <Darkside> :P
[10:08] <Darkside> i shoudl be able to boost the uplink power nicely though
[10:08] <Darkside> and i still want to try and uplink using a ham radio
[10:09] <Darkside> i'm thinking GMSK with a low baud rate should do it
[10:09] <navrac> yep - good idea. I might possibly have been running 100mW on the ground tx into a 10dB antenna to clear the message
[10:10] <navrac> I think so - I couldnt get anything less that 500 or 512? baud to work
[10:10] <Darkside> ok
[10:11] <Darkside> could tyou send me the code that was on the payload?

[11:18] <navrac> question is - should i plug up the aerials for sharp or leave it an hour or so
[11:18] <eroomde> i'm gonna put them up soon
[11:19] <eroomde> usually launches with less experienced teams are announced like this (I don't mean this rudely at all):
[11:19] <eroomde> "It's up! but we can't hear it! CALLING ALL LISTENERS"
[11:19] <eroomde> and it's a mad scramble
[11:20] <eroomde> i say less experienced, experienced people do it too :)
[11:20] <Graeme_SHARP> Hehe, fair comment ed, but we've got 2 successful launches under our belt so are getting better at sticking to time a bit :)
[11:20] <DeaneyBabey> ish
[11:21] <DeaneyBabey> :P
[11:21] <Graeme_SHARP> Btw eta to launch site 2 minutes :) and Jake :p
[11:21] <navrac> my team consists of an 80+ year old radio ham who cant work fldigi, a 12 year old boy and a rather heavily medicated guy who often can't remember what day it is
[11:21] <eroomde> it's not so much sticking to time, more comms with the irc channel

[11:22] <eroomde> it's quite fun to be ready and waiting on the right freq to see how low you can get a good decode in
[11:23] <navrac> yep i enjoy that too - annoying when you get a good low signal but for some reason you cant decode and you watch the altitude going up on spacenear thinking 'i could have had that one'
[11:23] <navrac> if they are only just at the launch site then 1 hour minimum?
[11:26] <eroomde> you can go from arrive to in the air in 20 minutes if you go for it
[11:26] Mike_SHARP (984e3f21@gateway/web/freenode/ip. joined #highaltitude.
[11:26] <eroomde> so a high risk strategy :)
[11:26] <number10> I have time to do your lawn then
[11:26] <eroomde> we'll just have to hope Graeme_SHARP gives us some headsesupses
[11:27] <eroomde> i've often thought for bigger launches there should be a fulltime media person
[11:27] <Udin_SHARP> We will do once everything is in place

[11:28] <Udin_SHARP> Nope we are in one of the computer rooms at Uni today
[11:28] <eroomde> ah
[11:28] <eroomde> but then that doesn't get round the launch info block
[11:29] <eroomde> in terms of having a 30s headsup that launch is about to happen
[11:29] <eroomde> that's what i'd quite like today if poss as i'm quite close to your launch site and would really like to see how long it takes to get a signal in
[11:29] <eroomde> would be interesting data
[11:30] <Graeme_SHARP> eroome: Andrew: if I remember, no problem!
[11:31] <eroomde> what i've done in the past is called someone on irc

[11:32] <eroomde> which they can relay in real time on irc

[11:36] <Darkside> as in, ascending beeps?
[11:36] <Darkside> (well, if you're going up)
[11:36] <G0DJA> I asked a local and apparently there's a modle aircraft club up the road in Clowne, so it might have been something to do with them
[11:37] <G0DJA> model = even
[11:37] <Matt_soton> btw anyone know what the highest bitrate mode fldigi does that isnt rtty?
[11:37] <G0DJA> BPSK-500 is pretty fast
[11:37] <r2x0t> QPSK-500
[11:38] <eroomde> Graeme_SHARP: basically, if the announcement of launch can be relayed to IRC within 10s or so of it actually happening, by some form of ingenuity on your team's part, that would be appreciated
[11:38] <eroomde> that is all
[11:38] <eroomde> even better if a fre-launch dial frequency could be provided too
[11:38] <G0DJA> Contestia can be faster
[11:38] <eroomde> then we can be sure to be in with a chance of a good low altitude string capture
[11:38] <Mike_SHARP> eroomde: I'm sure we can work something out
[11:38] <Graeme_SHARP> sure - should be possible
[11:38] <eroomde> ta
[11:39] <Matt_soton> mm another criteria, fsk based modes only
[11:39] <r2x0t> 1200Bd/850Hz FSK
[11:39] <Matt_soton> so constestia seems good
[11:39] <r2x0t> or maybe better make it 1200Bd/600Hz
[11:39] <r2x0t> that's MSK
[11:40] <Matt_soton> i suppose theres no reason why with 20dB SNR rtty wont work
[11:40] <Darkside> 1200 baud is pretty dodgy in dl-fldigi
[11:40] <eroomde> yeah
[11:40] <Darkside> i think 600 is a bit more reliable
[11:40] <Darkside> but still iffy
[11:40] <r2x0t> fl-digi uses two filters
[11:40] <Darkside> we use 300 on all our payloads
[11:40] <eroomde> keep the symbol rate low is my experiece with dl-fldigi
[11:40] <r2x0t> so you need non-overlapping tones
[11:41] <eroomde> increase the value of M instead
[11:41] <Matt_soton> well the fldigi mode info page seems to think contestia 'is a family of MFSK modes'
[11:41] <r2x0t> contestia IS MFSK
[11:41] <eroomde> dominoex looks like a good mode. it's MFSK with FEC built into the standard. it's differentially coded which means it's quite tolerant of drift
[11:42] <eroomde> it's not the fastest data rate but it has a lot of pleasant things that make it worthy of consideration
[11:42] <Darkside> and there's code already written to do it :P
[11:42] <r2x0t> dominoex is differential and slow...
[11:42] <eroomde> if you want something 'standard'
[11:42] <r2x0t> all these modes were made for HF
[11:42] <Darkside> yeah, domioEX is sloooow tho
[11:42] <Graeme_SHARP> does anyone know why SHARP isn't on spacenear.us? jonsowman set it up yesterday and it was on there last night...
[11:42] <G0DJA> If you were thinking of Contestia I'd suggest Olivia instead though
[11:42] <Matt_soton> dominoex22 is 160wpm
[11:42] <Darkside> if you want fast data rates, you want to be using 1200 baud AFSK or somehting and decent output power
[11:42] <Matt_soton> contestia 117 max
[11:42] <Darkside> or at least, thats what we do here
[11:43] <Matt_soton> so is AFSK better then straight FSK?
[11:43] <Darkside> if you're limited to 10mw... then you have to approach the problem differently
[11:43] <Matt_soton> AFSK needs FM reciever?
[11:43] <Darkside> Matt_soton: no, its just that AFSK is what APRS uses
[11:43] <gonzo_> ssb
[11:43] <Darkside> it also needs a shitload more SNR
[11:43] <r2x0t> AFSK = FM with FSK in audio
[11:43] <Darkside> yes
[11:43] <r2x0t> stupid
[11:43] <r2x0t> unless you really HAVE TO use FM rx
[11:43] <priyesh> Graeme_SHARP: you'll need to successfully decode the first packet for it to show up
[11:43] <gonzo_> oops, you were right FM
[11:43] <Darkside> r2x0t: very tolerant of drift though
[11:44] <Matt_soton> well i (will) have a DAC on a standard crystal pulled radio so im seeing what i can get through it
[11:44] <Graeme_SHARP> priyesh: thanks. I was just wondering why it isn't under planned launches (it was yesterday)
[11:44] <r2x0t> also even with FM radio
[11:44] <r2x0t> you can always mod it
[11:44] <Darkside> Matt_soton: you're still limited by 10mW though, right?
[11:44] <UpuWork> https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-prn1/564075_3345913458267_1581700325_2687920_409662678_n.jpg
[11:44] <Matt_soton> it would seem fldigi doesnt have any faster modes, but they are better for error correction
[11:44] <r2x0t> use direct discriminator output
[11:44] <Matt_soton> Darkside: yea
[11:44] <r2x0t> then you can rx FSK
[11:44] <Darkside> Matt_soton: well then go a MFSK based mode
[11:44] <priyesh> Graeme_SHARP: i don't remember seeing it, but perhaps you should speak to UpuWork
[11:44] <mfa298> Graeme_SHARP: do we have any rough idea of when launch might be (might need to go home to prod something) but I have meetings this afteroon so I'm not sure if it's worth it.
[11:44] <Matt_soton> such as domineoex
[11:44] <Matt_soton> but its still not actually faster
[11:45] <Darkside> olivia would be reeeealy cool to get going, but i'm pretty sure it uses multiple tones at teh same time
[11:45] <UpuWork> see what ?
[11:45] <r2x0t> no, olivia is normal MFSK
[11:45] <Darkside> ooook
[11:45] <r2x0t> one tone at a time
[11:45] <Darkside> ooooooh
[11:45] <Darkside> someone implemenet that :D

[11:45] <eroomde> i think if you're in the uk and constrained to ntx2 and 10mW, then some kind of MFSK spread over a couple of KHz is probably the best we can do
[11:45] <r2x0t> but coding may be hard, it's quite complex
[11:45] <Darkside> olivia is awesome, can be decoded whtn its on the noise floor
[11:45] <r2x0t> also SLOW
[11:45] <Matt_soton> 'The typing speed is varied by changing the number of tones used'
[11:45] <Matt_soton> so yep
[11:45] <Darkside> olivia would be awesome for a HF floater payload
[11:45] <eroomde> i think we should be able to get about 1.2kb info rate though. it's a good thing to aim for
[11:45] <priyesh> UpuWork: Graeme_SHARP is asking if sharp was removed from spacenear.us
[11:46] <priyesh> i don't remember seeing it since the last launch
[11:46] <r2x0t> see... this is reason we need some new mode for higher rates with error correction and all the nice stuff
[11:46] <G0DJA> Darkside - Yes Olivia is a multi-tone system
[11:46] <UpuWork> well the previous flight was yes but no current location information being uploaded
[11:46] <Graeme_SHARP> priyesh: jonsowman added it back yesterday (I think...)
[11:46] <Matt_soton> apparently MT-63 is supposed to be good at low signal, but thats basically ofdm
[11:46] <priyesh> Graeme_SHARP: didn't jon just add a flight doc
[11:46] <Darkside> yeah, you'll need a whole different transmitter to be able to do OFDM modes
[11:46] <Matt_soton> r2x0t: the goal in the end, but for now we have dlfigi
[11:46] <G0DJA> Ah yes, I see what you mean, it transmits several tones but sequencially
[11:47] <r2x0t> olivia may be interesting project
[11:47] <r2x0t> for very low snr
[11:47] <Darkside> i'd really like to do olivia on HF
[11:47] <r2x0t> and low rate data
[11:47] <Darkside> that would be a very cool payload
[11:47] <r2x0t> but tones have to be precisely keyed
[11:47] <Matt_soton> i was always wondering if ofdm based/olivia would be better at low snr as you are splitting your transmit power across multiple tones
[11:47] <r2x0t> timing and frequency precision is important
[11:47] <eroomde> mmm
[11:47] <r2x0t> Matt_soton: you are not splitting anything with MFSK
[11:47] <r2x0t> always sending ONE tone at a time

[11:48] <Matt_soton> yea but olivia you are
[11:48] Nick change: Udin_SHARP_ -> Udin_SHARP
[11:48] <r2x0t> olivia is one tone at a time
[11:48] <Darkside> r2x0t: precide frequency is doable, particularly on hf
[11:48] <Darkside> precise*
[11:48] <eroomde> if you do something more clevererer than matched filters and a discriminator
[11:48] <Darkside> i've got harware to do that already
[11:48] <r2x0t> yes, but not on 70cm...
[11:48] <r2x0t> for HF payload tx it's good
[11:48] <Darkside> r2x0t: yes, i'm not working on 70cm here >_>
[11:48] <G0DJA> And you have a GPS to lock time to LOL
[11:48] <Darkside> r2x0t: i don't have the restrictions you guys havre
[11:48] <Matt_soton> is this frequency stable as in changing transmit frequency?
[11:49] <r2x0t> just look into olivia code
[11:49] <gonzo_> it seems that most of the HAB community are ok with writing software, but the radio experience is limited. So any new modes are limited to what can be implimented on plug and play radio hardware
[11:49] <G0DJA> You don't really want the frequency drifting about with a mode like Olivia
[11:49] <r2x0t> it's MFSK + gray tone mapping + interleaving + viterbi
[11:49] <eroomde> yes something that made me think dominoex was attractive for hab is the freq drift tolerance
[11:50] <eroomde> sharp chase on the map for me now
[11:50] <G0DJA> Anyone else used ROS?
[11:50] <eroomde> ROS?
[11:50] <Matt_soton> well it wont be an issue for my HF transmitter, but UHF frequency drift would need compensating
[11:50] <r2x0t> depends on what drift you are talking about... olivia will cope with something like 100Hz/minute easily
[11:50] <Matt_soton> might just use dominoex
[11:50] <Matt_soton> that seems to have the highest datarate
[11:50] <G0DJA> Not sure it would be any better than Olivia and maybe also intollerant of frequency drift
[11:50] <eroomde> r2x0t: on wednesday we were seeing about 2khz/min sometimes :)
[11:51] <r2x0t> eroomde: that's why I said it's not good for 70cm, only HF with good tx
[11:51] <Matt_soton> was that astra1 eroomde ?
[11:51] <eroomde> yes
[11:51] <Matt_soton> yea tahts what you get from a non-insulated ntx2
[11:52] <Matt_soton> actually MFSK64 is fastest
[11:53] <r2x0t> because it's uncoded
[11:53] <r2x0t> no error correction
[11:53] <eroomde> so maybe as a fun experiment we should through together a new mode to see just how much we can get out of these NTX2s
[11:53] <eroomde> some kind of widish differentially coded MFSK with decent error correction
[11:53] <r2x0t> that's what I'm working on it...
[11:54] <r2x0t> but for rfm22b as it does GMSK
[11:54] <eroomde> and maybe more sophisticated receiving software
[11:54] <eroomde> this goal of >1kb/s without needing an artillery section of yagi antennas is quite appealing
[11:54] <Matt_soton> this page reckons mfsk64 is 1/2 rate coded
[11:55] <r2x0t> eroomde: my SNR comparison says you need same SNR for 300Bd FSK or experimental coded 2400Bd GMSK
[11:56] <r2x0t> so it's certainly doable...

[11:57] <Rhys_SHARP> Whats the news from SHARP
[11:58] <Matt_soton> so MSK is FSK but the transition between frequencies occurs at 0V output?

[11:58] <r2x0t> MSK is FSK with shift=baudrate/2
[11:58] <r2x0t> this transforms it into OQPSK signal

[11:59] <Matt_soton> oh thats it, seems simple enough

[11:59] <Graeme_SHARP> *putting
[11:59] <r2x0t> and can be received using costas loop based decoder that in ideal implemtation gives you +3dB

[12:02] <NigeyS> Graeme_SHARP: hows things going down there ?
[12:03] <Matt_soton> either way, looks like its mfsk64, assuming it actually does have error correction
[12:04] <ael> right, AEL setup and listening on 434.650
[12:04] <ael> though a dial freq at the launch site would be appreciated too

[12:05] <ael> Matt_soton: is mfsk64 drift tolerant?
[12:05] <Matt_soton> erm who knows
[12:05] <UpuWork> radio @ launch site this time ?
[12:05] <Matt_soton> if not ill compensate the crystal
[12:05] <Matt_soton> or just use the 27.12M transmitter :P
[12:05] <G0DJA> ael I've even got the 432<>28MHz transverter and SDR running on the beam today - organised for a change!
[12:05] <ael> the standard knows :)
[12:05] Nick change: Udin_SHARP__ -> Udin_SHARP
[12:06] <mfa298> UpuWork: I'm suspecting there's only one radio again with andrew_apex. But I don't know if he's at the launch site or elsewhere.
[12:06] <ael> i mean if it's not differentially coded it's inherently not going to be that drift tolerant
[12:06] <ael> unless you have some super clever tracking algorithm at the receiver
[12:06] <ael> not having a radio at the launch site is mega dodge chaps
[12:07] <ael> you don't know if it's working or not before you let go!
[12:07] <r2x0t> depends on sw... MFSK can be tracked using FFT or tone phase
[12:07] <Rhys_SHARP> I believe Andrew_apex should be at launch
[12:07] <Laurenceb> anyone here used openoffice?
[12:07] <NigeyS> Laurenceb: very rarely, mainly for WP .. having issues ?
[12:08] <Rhys_SHARP> He will def be only one with radio
[12:08] <Laurenceb> i want to grab a graph
[12:08] <Laurenceb> as a png
[12:08] <Laurenceb> i cant work out how to highlight it
[12:08] <Laurenceb> i can only highlight cells atm
[12:09] <NigeyS> hmm never tried tbh
[12:09] <NigeyS> prolly some stupid key combo
[12:10] <G0DJA> I have OpenOffice on this PC but it's a bit on the 'clunky' side!
[12:10] <Laurenceb> lol i could use printscreen
[12:10] <Laurenceb> that would be daft tho
[12:10] <Matt_soton> well fldigi does a pretty crap job of trying to 'find' a mfsk-64 signal
[12:10] <Matt_soton> itll cope with slow drift
[12:11] <Laurenceb> yeah
[12:11] <ael> so to summarise this fun conversation from earlier, there'd be some mileage in trying to make something to get the most out of an ntx2 and ssb receiver, some kind of quite wide (eg 2khz) MFSK with a good error correction code scheme
[12:11] <Laurenceb> it doesnt do afc well
[12:11] <Udin_SHARP> Ok
[12:11] <G0DJA> There's a discussion at http://www.oooforum.org/forum/viewtopic.phtml?t=41418 if it's of any use?
[12:11] <Laurenceb> but it decodes well
[12:11] <Udin_SHARP> we aim to go up between 1330 and 1400
[12:11] <Laurenceb> ive done it with printscreen and gimp :P

[12:12] <daveake> Er, landing on my head then?
[12:12] <G0DJA> I find IrfanView easier to use than Gimp
[12:12] <Udin_SHARP> We will let you know if there is a delay
[12:12] <ael> thanks
[12:12] <Udin_SHARP> and flight time should be under 2h
[12:12] <ael> nice short (in terms of distance over the ground) flight
[12:13] <ael> you might even be able to see it come down

[12:30] <ael> 325 according to dlfldigi
[12:31] <Darkside> woo, got my RFM22B doing 425Hz shift
[12:31] <Darkside> or thereabouts
[12:31] <Darkside> and doing 300 baud
[12:31] <Darkside> navrac: do you have any pictures of what you did to your RFM22B?
[12:31] <Matt_soton> whats the lowest shift those things can do?
[12:31] <navrac> how did you get 425?
[12:31] <Darkside> like, with the metal and the silicone?
[12:31] <Darkside> Matt_soton: about 170Hz
[12:31] <ael> i'm sure i can hear rtty in all the noise
[12:31] <ael> annoying how your brain does that to you
[12:31] <Darkside> navrac: i modified the twiddle factor
[12:32] <Darkside> rf22.spiWrite(0x073, 0x03);
[12:32] <Darkside> instead of 0x01
[12:32] <navrac> oh right err. - i thought that was 156*3
[12:32] <jonsowman> all good here?
[12:32] <ael> so far
[12:32] <ael> nothing flying yet
[12:32] <jonsowman> cool
[12:32] <ael> am ready and waiting :)
[12:32] <Matt_soton> im hoping to get a radio that can tune the entire 434 band but with fine carrier shifts
[12:32] <Darkside> navrac: so is each unit of that 156Hz?
[12:32] <jonsowman> Matt_soton: joey :P
[12:33] <jonsowman> soon
[12:33] <navrac> 156.25 i think - memories a bit shot

[12:33] <Darkside> i'm transmitting at 431.650MHz
[12:33] <Matt_soton> with less loop filters
[12:33] <Darkside> well, thasts what i set it to - i'm hearing it at 431.646MHZ :P
[12:33] <Randomskk> Matt_soton: I still don't think the loop filter was that big a deal
[12:33] <Randomskk> it's like two resistors and three capacitors
[12:33] <navrac> 073 is the afc /fine tune reg isnt it?
[12:33] <Matt_soton> yea it shouldnt be, but it seemed to cause you issues?

[12:34] <Randomskk> not the loop filter

[12:34] <Matt_soton> oh ok
[12:34] <jonsowman> terrifying
[12:34] <Matt_soton> the vco inductor?
[12:34] <Randomskk> replacing the loop filter did not help
[12:34] <Randomskk> replacing the vco inductor did
[12:34] <Matt_soton> just blame the inductor
[12:34] <Matt_soton> is always the inductor
[12:34] <Matt_soton> they are a pain
[12:36] <Laurenceb> one of the reasons single conversion is nice
[12:36] heathkid|2 (~heathkid@unaffiliated/heathkid) joined #highaltitude.
[12:36] <Randomskk> time to set up the radio, brb
[12:36] <ael> i recently had to blame the inductor
[12:36] <ael> an 0603 resistor had too much inductance
[12:36] <ael> was freakin on ma ghz
[12:37] <Matt_soton> oh GHz explains that
[12:37] <Darkside> navrac: hmm, i tell it to go into RX mode, but its still transmitting a carrier
[12:37] <Darkside> or do i have to do it in a certian order
[12:37] <Darkside> hrm
[12:38] <navrac> darkside: DesiredOffset = 156.25Hz*(hbsel+1)* fo[ 9:0]
[12:38] <ael> it's because they size the resisotrs by cutting a helix on the metal film was a laser
[12:38] <ael> and that helix is relatively inductive
[12:38] <navrac> since hbsel is 0 for the 400meg range the tuning offset should be steps of 156.25hz
[12:38] <Matt_soton> so a 1206 resistor would be straigher and less helixy?
[12:38] <ael> unsure
[12:39] <navrac> using the RF22 library?

[12:41] <navrac> 40 minutes into lunch window - biab
[12:41] <Darkside> navrac: i'm trying to make it transmit a burst of RTTY, with receive gaps in between
[12:41] <jonsowman> i can't see them being done by 3pm tbh
[12:41] <jonsowman> unless they fil it for 20m/s ascent
[12:41] <Randomskk> jonsowman: I was thinking about this
[12:41] <Randomskk> I reckon you could do really high neck lifts if you changed how you filled
[12:42] <Matt_soton> is this the heavier then usual payload though?
[12:42] <Udin_SHARP> We are not going that high
[12:42] <Randomskk> neck payload plus a one way valve in the bottom
[12:42] <Matt_soton> wont go that high
[12:42] <Randomskk> bond it /firmly/ to the balloon
[12:42] <Randomskk> then just plug helium in the bottom
[12:42] <Randomskk> keep it tied down with some cord
[12:42] <Randomskk> fill to excesss
[12:42] <gonzo_> the way the modules drift, it's probabl that we would get away with both HABs being up at the same time
[12:42] <Randomskk> cut the cord
[12:42] <Randomskk> (well remove the fill tube first)
[12:42] <Udin_SHARP> Matt_soton yes this is the heaviest we will fly
[12:42] <Randomskk> so you don't have to hold on to the balloon
[12:43] <Matt_soton> i thought tht too gonzo_ , sharp is off for alot of the time anyway
[12:43] <Udin_SHARP> just under 2kg
[12:43] <Matt_soton> nigel might not agree
[12:43] <ael> gonzo_: noooo
[12:43] <jonsowman> Randomskk: it will move around all over the place in wind
[12:43] <Matt_soton> hold it down under a net?

[12:44] <ael> just doing things conventionally
[12:44] <ael> you just need to hold on tight
[12:44] <jonsowman> ael: was it windy?
[12:44] <ael> quite
[12:44] <Matt_soton> the highest ive seen is 32kg or so, but that doesnt count :P
[12:44] <Randomskk> ael: jon won't let me try more than about 5kg :P
[12:44] <Matt_soton> might have been 42 kg...
[12:44] <ael> enough that our tethers, which were 3 x 25kg weights, got pulled along the field as if they weren't there
[12:44] <Randomskk> possibly as jon seems to end up holding the payload

[12:57] <Randomskk> wow libjsoncpp is a total pain to build
[12:57] <ael> it's categorically wasn't the last time i recall it being tried
[12:58] <jonsowman> oh really?
[12:58] <ael> yah really
[12:58] <jonsowman> the signal is only a few hundred hz bandwidth from each
[12:58] <ael> if their centre freqs got closer than about 1khz it started causing problems
[12:58] <ael> spectral leakage i guess
[12:58] <jonsowman> ah
[12:58] <jonsowman> i see
[12:59] <jonsowman> you know those trimcaps on the NTX2
[12:59] <jonsowman> i wonder how far you can change their frequency

[13:02] <ael> hopefully that'll catch it from the get-go
[13:03] <Rhys_SHARP> Sounds about right

[13:07] <Randomskk> right, cool
[13:07] <Randomskk> dl-fldigi set up and working
[13:07] <jonsowman> got libjsoncpp to build?
[13:07] <Randomskk> not that I'm particularly expecting to get much on the whip
[13:07] <Randomskk> nah, changed the ppa to use oneiric and installed that
[13:07] <Randomskk> worked
[13:07] <Randomskk> I tried
[13:07] <Randomskk> I got libjsoncpp to build
[13:07] <jonsowman> cool
[13:07] <Randomskk> but could not install it ???
[13:07] <Randomskk> scons is horrific
[13:07] <jonsowman> hehe
[13:07] <Randomskk> it wanted me to download all of scons then extract it into the libjsoncpp source folder
[13:07] <Randomskk> then run the python script
[13:07] <Randomskk> then it did build
[13:07] <Randomskk> but had no install target
[13:08] <jonsowman> right
[13:08] <Randomskk> so no idea what it wanted me to do
[13:08] <jonsowman> well that makes sense
[13:08] <Randomskk> also I think they named it json.cpp which clashes
[13:08] <Randomskk> so danielrichman's named it something else
[13:08] <Randomskk> so in the end I just installed his :P
[13:08] <Randomskk> anyway dl-fldigi has built so I'm happy
[13:08] <jonsowman> yeah

[13:21] <ael> Graham_G3VZV: you're aware it might be delayed?
[13:21] <Graham_G3VZV> nope:)
[13:21] <ael> i think the agreement that sharp and nigey reached was that sharp would do their launch at 1 and be down by 3
[13:21] <ael> so picochu could launch at about 3
[13:22] <ael> but sharp are still doing whatever they're doing at the launch site
[13:22] <ael> no launch yet
[13:22] <ael> this was to get around the potential freq clash as they're both on 650
[13:22] NigelMoby (~nigel@ joined #highaltitude.
[13:23] <ael> latest shrp launch estimate was 2:15 - 2:30
[13:24] <ael> so hopefully in the next 5 minutes or so
[13:25] <DeaneyBabey> its going to be a short flight if they want done by 3pm!
[13:25] <DeaneyBabey> 20 minutes up - then cutdown?
[13:25] <jonsowman> yea.. i think the bets are on that not happening
[13:26] <pjm__> is there some balloon up currently?
[13:26] <jonsowman> i think just having it in the air by 3 will be the new aim
[13:26] <jonsowman> not yet pjm__ ... soon

[13:26] <jonsowman> i should stop saying "soon" before someone links to another scary thing on the internet
[13:26] <fsphil> another?
[13:26] <kokey> is it delayed due to air friction damage from the high velocity trip from Kazakhstan?
[13:27] <OZ1SKY_Brian> dont like the idea of cutdown, could mean ballon monitoring is over for me :-)

[13:30] <Udin_SHARP> We know ael
[13:31] <ael> i'm telling G0DJA

[13:31] <ael> asked*
[13:31] <Udin_SHARP> but unfortunately there is very little we can do at mission control
[13:31] <G0DJA> We used to have 'windows' at work for things that were meant to happen, the joke was they either became patio doors or roof lights...

[13:32] <OZ1SKY_Brian> G0DJA its the ish factor :-)
[13:32] <r2x0t> it's their 3rd launch, you would expect they already know timing...

[14:23] <ael> is it possible to clear the nonesense on pichu?
[14:23] <Darkside> i'm happy to have a limited set of commands
[14:23] <ael> picochu*
[14:23] <Laurenceb> theres no stop bits are there?
[14:23] <Darkside> ael: no, and no point
[14:23] <Darkside> Laurenceb: dont think so
[14:23] <r2x0t> ael: reload
[14:23] <Laurenceb> so itd be hard to use fldigi
[14:23] <Darkside> Laurenceb: yah
[14:23] <Laurenceb> it uses sync sequence
[14:24] <Laurenceb> the bit edge tracker
[14:24] <ael> Darkside: ?
[14:24] <Laurenceb> *thenm
[14:24] <Laurenceb> arg i cant speel
[14:24] <Darkside> anyway, the way i'm doign it at th emoment, is i have it transmit a burst of RTTY - i centre the RTTY transmission over 1500Hz in fldigi, then transmit the packet on the same radio
[14:24] <Laurenceb> ok
[14:24] <Darkside> that way it ensures the transmitted packet lines up with the GMSK receive filters
[14:24] <r2x0t> Darkside: you feeding it to tx radio in SSB mode or FM mode ?
[14:24] <Laurenceb> you know the rfm22b is actually an si4432 right?
[14:24] <Darkside> r2x0t: SSB
[14:24] <Darkside> Laurenceb: yes
[14:24] <Laurenceb> so you can make a custom board and use dual ant etc
[14:25] <Laurenceb> mouser stock it
[14:25] <navrac> but not 50W
[14:25] <Darkside> yeah but i've already got a small pile of boards :P
[14:25] <Darkside> navrac: GMSK uplink!
[14:25] <Darkside> i'm going to need to range test this
[14:25] <Darkside> obviously
[14:25] <navrac> well done
[14:25] <ael> r2x0t: ta
[14:25] <ael> daveake: few seconds to go
[14:26] <ael> i wonder if it's like that scene in Independence Day
[14:26] <daveake> :)
[14:26] <navrac> i managed 43km at 28dBm - but from ground level thru tress
[14:26] <ael> where they blow up the mother ship but the blast catches up with them
[14:26] <ael> i imagine that's what getting LOS will be like
[14:26] <upix> why is PicoChu going up so slow?
[14:26] <r2x0t> it's picolaunch
[14:26] <r2x0t> slow up, slow down
[14:26] <Laurenceb> navrac: using a better xtal would have thelped you too
[14:26] <craag> What's the expected burst alt for picochu?
[14:27] <Laurenceb> i think the rfm22b xtal is quite poor
[14:27] <ael> anyone got it yet?
[14:27] <Matt_soton> wait, so did sharp fill a balloon then realise no lock?
[14:27] <Laurenceb> so you need a good signal for the si4432 afc to pull in
[14:27] <r2x0t> you can send multiple packets so rfm can better lock to it
[14:27] <r2x0t> it may take some time for AFC to find signal
[14:28] <Mike_SHARP> Matt_soton: procedural error
[14:28] <Darkside> Laurenceb: yeah i'm thinking of trying to replace the crystal on one of these RFM22bs
[14:28] <Darkside> it has pads for a surface mount HC49 style crystal
[14:28] <Laurenceb> ok
[14:28] <ael> i think i can see picochu on my waterfall
[14:29] <ael> no decodes yet though
[14:29] <Upu> dial ?
[14:29] <Laurenceb> it can also use a tcxo input
[14:29] <Matt_soton> so its temperature drift is less?
[14:29] <ael> 650.050
[14:29] <ael> yep there she is
[14:29] <ael> like a developing phgotograph
[14:29] <ael> getting strong and stronger
[14:29] <Laurenceb> you could even have a vcxo locked to the gps 1pps

[14:29] <ael> this is pre hgorizon for me
[14:30] <Matt_soton> i can see but cant decode
[14:30] <Laurenceb> annoyingly iirc stm32 cant run off 30mhz
[14:30] <NigelMoby> in car signal ok ael?
[14:30] <Laurenceb> tho si4432 can run off 10mhz or something iirc?
[14:30] <Darkside> Laurenceb: the one i have uses 30MHz
[14:30] <Laurenceb> yeah
[14:31] <Darkside> i'm thinking of using a better quality 30MHz crystal
[14:31] <Laurenceb> stm32 clk input is max 25mhz or something
[14:31] <ael> hmm it seems to have wandered off again
[14:31] <Laurenceb> at least on f1
[14:31] <ael> lucky ducting maybe
[14:31] <G0DJA> It'll need to get to a good height to clear the Pennines from here
[14:31] <Darkside> i reckon i can rework the current crystal off the board.
[14:31] <Randomskk> itym sporadic E
[14:31] <Upu> I don't have much luck with these G0DJA
[14:31] <Upu> not from Wales

[14:32] <Matt_soton> almost decoding
[14:32] <Matt_soton> at 3528m?
[14:32] <pjm__> is there some special mode for this?
[14:32] <Upu> what freq are you on Matt_soton ?
[14:32] <pjm__> its loud with me but no decode in fldigi
[14:32] <Upu> 1528
[14:32] <Matt_soton> .650
[14:32] <Matt_soton> and the top rtty tone is at 2k
[14:32] <ael> i can just see it in the waterfall but no decoding
[14:33] <daveake> decoding now
[14:33] <ael> still don't have LOS
[14:33] <ael> hurry up stupid payload
[14:33] <G0DJA> I'll grab a cuppa whilst it gets a bit more height
[14:33] <ael> ascend
[14:33] <navrac> nice one daveake - using the funcube i hope
[14:33] <Upu> actually pretty fast ascent for a pico

[14:50] <LazyLeopard> Thanks. Faint traces on waterfall here...
[14:50] <ael> am getting close
[14:50] <upix> could anyone explain what does term waterfall mean
[14:50] <Upu> have you downloaded dl-fldigi ?
[14:51] <upix> me?
[14:51] <Upu> yes
[14:51] <upix> no
[14:51] <Upu> ok
[14:51] <upix> haven't got a receiver
[14:51] <upix> so no use of fldigi
[14:51] <Upu> the water fall is the part of dl-fldiig that shows the signal graphically
[14:51] <G0DJA> upix its the part of the display where the pixels created by the received audio 'scrolls' up or 'down' the display (dependant on the setting and/or program you are using
[14:51] <upix> ah
[14:51] <upix> thanks
[14:52] <Upu> http://i.imgur.com/pqBiI.png
[14:52] <G0DJA> It looks like a stream of water cascading down so hence the term "waterfall"
[14:52] <Upu> that yellow fuzzy bit is waterfall
[14:52] <Upu> the signal is the red lines
[14:52] <navrac> it shows the audio frequency along the bottom and if there is a signal at a particular frequency it put a brighter dot - then it keeps adding lines over time
[14:52] <G0DJA> You have your audio set up high Upu!
[14:53] <Upu> oh that was the other day
[14:53] <Upu> that isn't a good example and is wrong
[14:54] <G0DJA> upix on my SDR screen the 'water' flows upwards, but in FLdigi it flows downwards
[14:54] <navrac> http://navrac.imgur.com/all/
[14:54] <Upu> navrac's images are not publicly available.
[14:54] <daveake> I assume the SHARP launch is off now so I won't be getting a free payload landing in my garden?
[14:54] <ael> daveake: potentially not just yet
[14:54] <navrac> the bottom waterfall is the fldigi one in that pic - you can see the low and high tones from the rtty
[14:55] <Udin_SHARP> daveake no there is no way we can fix it and get it down before sunset
[14:55] <navrac> http://i.imgur.com/QCzgf.jpg
[14:55] <daveake> ok thanks
[14:55] <navrac> sorry - that was the logged in address before
[14:56] <Randomskk> hmm inside the blue horizon
[14:56] <Udin_SHARP> daveake I was wrong
[14:56] <navrac> this ascent rate is far too slow
[14:56] <Randomskk> nothing yet
[14:56] <ael> getting stronger signals now
[14:57] <ael> still not an error-free decode though
[14:57] <upix> how long it will be going up and down
[14:57] <daveake> Been green for ages here
[14:57] <G0DJA> Camera work is jumpy and this is HF RTTY, but the waterfall can bee seen working http://www.youtube.com/watch?v=TWjanNni6mA
[14:58] <r2x0t> upix: this is potential floater, so may stay there for a long time
[14:58] <Randomskk> hmm my window is really the wrong way

[15:02] <Bob_G8NSV> bob_g8nsv hums bonnie tyler song
[15:02] <Randomskk> well the other part detached a little earlier but nevermind
[15:03] <daveake> Was the toy/whatever tethered?

[15:03] <daveake> Ah
[15:03] <Randomskk> and no, it was not tethered, so is presumably now somewhere in the countryside :P

[15:06] <upix> you can always make one

[15:07] <G0DJA> Lines getting stronger on the SDR
[15:07] <daveake> Nice clear signal here
[15:07] <Matt_soton> could be interesting to post
[15:08] <G0DJA> Must get round to turning the beam through 90 degrees and put the new one up for horizontal use...
[15:08] <daveake> The smaller (<=100mm) balls are solid but the larger (>=125mm) ones are hollow and in 2 parts.
[15:08] <navrac> altitude is leveling off a bit - I dont thin the blue line is going to make it to me :-(

[15:09] <Matt_soton> are they easy to find then?
[15:10] <Matt_soton> any craft shop?
[15:10] <daveake> HobbyCraft do the 125mm ones, but otherwise try ebay
[15:10] <daveake> 125mm you can fit in 1 or 2 Canon powershots

[15:27] <fsphil> less likely to float then

[15:28] <Randomskk> LazyLeopard: no fair, how come you can pick it up and I can't :P
[15:28] <NigeyS> well. it has very very low ascent rate, so that may stop a sudden buildup of pressure that causes burst, thats my thinking anyway
[15:28] <fsphil> yea
[15:28] <navrac> i think it could float - its low enought that the balloons wont split

[15:41] <daveake> Don't jump out of the aircraft without it
[15:41] <NigeyS> lol
[15:42] <Lunar_Lander> when I got a parachute, I can see on the spherachute site the size measured across the top and the diameter of the opening
[15:42] <NigeyS> upu what do i put in burst field for predicting the float E1 something isnt it ?
[15:42] <Lunar_Lander> which do I need to use to calculate the area for the velocity
[15:42] <Mike_SHARP> The diameter
[15:42] <navrac> just use 0.05 or 0.005 if youdont mind waiting
[15:42] <ael> Lunar_Lander: that depends on the other variable
[15:42] <ael> Cd
[15:42] <ael> does it give a Cd?
[15:43] <ael> Mike_SHARP: no please be careful giving advice unless you know for sure how the Cd is measured
[15:43] <Lunar_Lander> no Cd there
[15:43] <Mike_SHARP> Sorry, I'm assuming you're calculating drag
[15:43] <Mike_SHARP> ?
[15:44] <Mike_SHARP> and you know the Cd?
[15:44] <ael> so sometimes they give a Cd based on the 'construction' diameter. sometimes they give a Cd based on the 'inflated' or 'projected' diameter
[15:44] <Lunar_Lander> ah
[15:44] <Lunar_Lander> there is no Cd given at all

[15:51] <Lunar_Lander> oh ok
[15:51] <Lunar_Lander> and why is it doing that?
[15:51] <ael> this is because the parachute has a very low geometric porosity - gaps in the canopy - so the air will start spilling back out of the mouth of the canopy

[15:52] <NigeyS> yup, temp has gone up to

[15:56] <ael> so you often get very high Cd value. >1. This is because they measure vertical rate of descent. so if you have a 1:1 glide, you air speed is actually much higher than just your vertical rate of descent

[16:01] <Matt_soton> Randomskk: i have nothing on the S meter
[16:01] <mfa298> What dial and audio center are people using for PicoChu
[16:01] <priyesh> Graeme_SHARP: 650.900
[16:01] <Matt_soton> and i have 10dB snr
[16:01] <Randomskk> I'm on 650.372

[16:01] <NigeyS> mfa298, around 1500 center
[16:01] <ael> 434.650.55 which centre freq of rtty at 1339hz
[16:02] <Matt_soton> sharp shouldnt clash as pico is very warm
[16:02] <Matt_soton> or at least not for very long
[16:02] <ael> he heh heh
[16:02] <ael> gentleman's wager?
[16:02] <Randomskk> -11dB SNR though
[16:02] <ael> 6 here atm
[16:02] <mfa298> I might have been centered on some noise then.
[16:03] <ael> oh 11 now
[16:03] <ael> nice and stong
[16:03] <mfa298> the joy of remote controlling the station. Can only see the waterfall not hear the rtty
[16:03] <Graeme_SHARP> We've soldered the gps antenna back together and am thinking of letting up soon if there is no likelyhood of a clash
[16:03] <Upu> did you get your prediction answer nigeys ?
[16:04] <Lunar_Lander> well, thanks ael
[16:04] <NigeyS> no..lol
[16:04] <ael> I don't know if there's 'no' likelyhood of a clash
[16:04] <Upu> sec I'll run it
[16:04] <ael> but it'd be interesting to see what happens
[16:04] <Randomskk> hmm faded out a bit
[16:04] <ael> i know that's not much comfort for those whose payloads are flying
[16:04] <NigeyS> tnx dude, i totally forgot the params
[16:04] <Matt_soton> Graeme_SHARP: put a small hole in the inulation to make sure it gets colder :P
[16:04] <ael> PicoChu is likely to be up for a while
[16:04] <ael> and outlive sharp
[16:04] <Lunar_Lander> OK cu

[16:11] <fsphil> I wonder if it would help if we cooled the balloons down before launch
[16:11] <Udin_SHARP> just to check
[16:12] <Udin_SHARP> even if we would clash with picochu you would be able to pick it up during the period when our transmitter is off and receiving?
[16:12] <Randomskk> priyesh: hmm checking
[16:13] <Upu> Udin_SHARP its unlikely to clash but really its NigeyS's call

[16:20] <NigeyS> picochu-4 @ 800meters
[16:20] <Randomskk> anyway your package worked
[16:20] <Randomskk> and I have dl-fldigi working nicely
[16:20] <Randomskk> so I'm happy
[16:20] <DanielRichman> awesome. Sorry about lack of 11.10 packages
[16:20] <Randomskk> 10.10* :P
[16:20] <DanielRichman> uh, 10.10
[16:20] <DanielRichman> yeah that one
[16:21] <Randomskk> I will update to 12.04 when it comes out I think
[16:21] <Randomskk> and stay with that for a bit
[16:21] <DanielRichman> same. (I'm on 10.04 lol)
[16:21] <DanielRichman> the 10.04 packages work on 11.10 (haven't tried the other way around but I'd expect them to) so what you did should just be fine
[16:21] <DanielRichman> but I can upload a 10.10 build if you'd like
[16:21] <Upu> thats a leak NigeyS ?
[16:21] <Randomskk> it's okay this is fine
[16:21] <ael> i'm probably going to go to 12.04 and stay with it for a bit too
[16:22] <Randomskk> probably best to have building it from source workign anyway
[16:22] <ael> it's LTS isn't it?

[16:22] <Randomskk> DanielRichman: hmm when's the next debian release?
[16:22] <Randomskk> they're even slower than ubuntu LTSs >_>
[16:22] <ael> 2024
[16:23] <Randomskk> hah
[16:23] <Randomskk> I'm happy with ubuntu though I'll be binning unity but I think LTSs are enough for me
[16:23] <NigeyS> arch ftw :p
[16:23] <BrainDamage> debian is pretty much the standard wrt "ancient"
[16:23] <ael> yeah it'll be xubuntu lts for me
[16:23] <DanielRichman> Randomskk: you're asking the wrong person I think. But iirc they recently switched to "we'll do a release every 18 months" or something (I forget exactly what)
[16:23] <Randomskk> hm
[16:23] <DanielRichman> it used to be "yeah whenever, when it's ready"
[16:23] <Randomskk> ael: xmonad >_>
[16:23] <ael> and i do like arch too NigeyS. but not as a desktop os
[16:23] <BrainDamage> ie when you're being outrun by debian, it means your software is wayy too outdated
[16:24] <BrainDamage> I am using arch too, in fact, I was annoyed a lot by debian derivatives and the "break all at once policy"
[16:24] <BrainDamage> I think rolling release is the way to go
[16:24] <ael> i will run arch on a raspi
[16:24] <ael> use that for messing around

[16:25] <ael> and it was superb
[16:25] <ael> the wiki is a gift from the gods
[16:25] <BrainDamage> I tought there was an issue wrt drivers

[16:51] <daveake> If they don't get a move on it'll set off before they launch
[16:51] <mfa298> that does seem hardly worth it.
[16:52] <r2x0t> with all the delays, it will cut it off 50m above ground with all the luck

[16:53] <daveake> Do they have the sheet to catch it like in the video?
[16:53] <Mike_SHARP> Thing is they already filled the balloon hours ago, so if we don't launch it's a total waste of balloon and helium

[16:55] <Dan-K2VOL> I am bgeinning to despise this shoddy arduino Wire library, it does very inefficient I2C and can leave your chip locked in a while loop in the Wire library itself if the I2C bus is stuck

[16:56] <Randomskk> ael: got sharp at 300m? grumble
[16:56] <Dan-K2VOL> and sharp
[16:56] <ael> got sharp yes
[16:56] <ael> no complete decode tho
[16:57] <ael> getting both pico and sharp in 3khz passband
[16:57] <ael> at either end
[16:57] <nigelvh> I had a issue where some humidity would get between a couple of the i2c pins and it would totally freeze the chip. Since then I haven't used i2c on a flight.
[16:57] <Dan-K2VOL> that's likely an issue with flux or pcb contamination
[16:57] <Rhys_SHARP> Ael: interference or ok?
[16:57] <daveake> got sharp here
[16:57] <ael> uploading both sharp and pico to tracker
[16:57] <ael> good strings
[16:58] <Rhys_SHARP> Nice
[16:58] <ael> bit messy for sharp but getting the odd one
[16:58] <Dan-K2VOL> but either way, I2C is a great simple protocol, but man it needs a lot of error-handling and watchdog code if it's to fly
[16:58] <daveake> Approx 2.1kHz lower than picochu

[17:34] <Udin_SHARP> Is picochu leaking?
[17:35] <Bob_G8NSV> I made one years ago for 70cm, remember it working very well. I built one twice the size, 12dB but way more agro for 3db
[17:35] <NigeyS> Udin_SHARP, quite possible
[17:35] <gonzo_> think I have one for 23cm. Which was built but never tried
[17:37] <Bob_G8NSV> am thinking of building one from small co-ax and flying it on a solar balloon. You can cut them to give a downtilt
[17:38] <gonzo_> the erp is the limiting factor on LPD band

[18:46] <r2x0t> looks like it's on a field
[18:46] <daveake> I lost it at about 500m. Was afk otherwise might have got it a little bit longer
[18:46] <r2x0t> not on a tree
[18:46] <mfa298> either that or teleports do exist
[18:46] <daveake> I think SHARP should take a minor detour :)

[18:53] <Laurenceb_> looks like trees are ~30 to 40m high
[18:53] <Laurenceb_> so thats up to 150m asl to the tops
[18:53] <NigeyS> big ass trees !
[18:54] <Matt_soton> i think if it were at 150m i would still be able to hear it
[18:54] <Laurenceb_> dunno
[18:54] <Matt_soton> i suppose hard to telll
[18:54] <Laurenceb_> depends how much the wind slowed as it neared the ground
[18:54] <Matt_soton> after the 193 packet it slowly drfited off into the moise
[18:54] <Matt_soton> noise
[18:54] <Laurenceb_> if it continued at its previous rate it would have just scimmed the treetips
[18:55] <Matt_soton> at least theres no cord to tangle
[18:55] <Laurenceb_> but the wind usually slows as you get lower
[18:55] <Laurenceb_> last position at 193m is about 90m from the trees

[21:26] <daveake> Does it have parachutes?

[21:28] <fsphil-laptop> the inner green circle seems to be more than 5 degrees

[21:36] <eroomde> i'm gonna need to get me a bigger gun i think
[21:37] <eroomde> for these floaters
[21:37] <eroomde> just can't get much purchase on a 2km object at 200km away
[21:37] <Randomskk> you want like a small guided missile or something
[21:37] <eroomde> exactly
[21:37] <daveake> Just needs to listen to the telemetry

[21:49] <Randomskk> ah

[22:35] <Lunar_Lander> thanks
[22:35] <Lunar_Lander> reason
[22:35] <Lunar_Lander> 3.3V-3.3V OK
[22:35] <Lunar_Lander> GND-GND OK
[22:35] <Lunar_Lander> FTDI RX-GPS RX WRONG
[22:36] <Morseman> Was it a Ublox NigelMoby?
[22:36] <daveake> FTDI RX - GPS TX
[22:36] <fsphil-laptop> you're not the first to make that mistake Lunar_Lander
[22:36] <Lunar_Lander> daveake, system corrected
[22:36] <Lunar_Lander> I got that VisualGPS that was suggested by a person
[22:36] <Lunar_Lander> above
[22:36] <Lunar_Lander> it now scrolls out data in the Command Monitor
[22:36] <NigelMoby> yup morse
[22:37] <NigelMoby> max 6 with chip antenna
[22:37] <Lunar_Lander> $GPGSA,A,1,,,,,,,,,99.99,99.99,99.99*30
[22:37] <Lunar_Lander> for example
[22:37] <daveake> yep
[22:37] <Lunar_Lander> there is some kind of red LED in the window that flashes each time it writes something
[22:38] <Lunar_Lander> I think that would turn Green if we got lock
[22:38] <Morseman> Oh, I meant to ask. When people are sending GPS data, is it UTC or GPS time?
[22:38] <daveake> So your next task is to write a really simple Arduino program that reads bytes from Rx then sends them to Tx
[22:38] Zuph (~Zuph@96-28-181-206.dhcp.insightbb.com) joined #highaltitude.
[22:38] <Lunar_Lander> yeah, reads from GPS and sends to PC?
[22:38] <Lunar_Lander> r2x0t, thanks for the suggestion
[22:39] <Lunar_Lander> I found that VisualGPS is freeware?
[22:39] <daveake> Then you connect the GPS to the Arduino (same connections as above) and the PC will "see" what you transmit from your program
[22:39] <Lunar_Lander> and the XP version is shareware
[22:39] <Lunar_Lander> yea
[22:39] <Morseman> I found out the other day that 'GPS' time is 15 seconds off UTC...
[22:39] <Lunar_Lander> but daveake
[22:39] <Lunar_Lander> it still says "Fix not available"
[22:39] <Lunar_Lander> :(
[22:39] <NigelMoby> brb
[22:39] <daveake> It will till it gets a fix :p
[22:39] <Lunar_Lander> yea
[22:39] <Lunar_Lander> wow
[22:40] <fsphil-laptop> Morseman, payloads generally transmit gps time
[22:40] <Lunar_Lander> the signal quality window is like a histogram of bars with 0
[22:40] <fsphil-laptop> as there's no other time available
[22:40] <Lunar_Lander> but sometimes it suddenly displays only one big bar saying "28" and 5
[22:40] <Randomskk> fsphil-laptop: generally UTC not GPS time
[22:40] <Lunar_Lander> maybe satellite 5?
[22:40] <Randomskk> fsphil-laptop: GPS satellites provide the offset to UTC
[22:40] <fsphil-laptop> ah
[22:40] <Morseman> OK fsphil-laptop - I guess 15 seconds isn't a big discrepancy in the scheme of things
[22:40] <Randomskk> and most (almost all) receivers apply it and output UTC
[22:41] <fsphil-laptop> so it's converted
[22:41] <Randomskk> certainly NMEA sentences are all UTC
[22:41] <fsphil-laptop> gotcha
[22:41] <Randomskk> the ublox chips provide a status bit to tell you if the UTC offset is known or not
[22:41] <Lunar_Lander> but you all said ublox can receive indoors and stuff

[22:41] <Laurenceb_> hell yeah

[22:41] <Laurenceb_> its finally here
[22:41] <fsphil-laptop> depends on the indoors
[22:41] <fsphil-laptop> if you're in a metal cage it won't work :)
[22:41] <Lunar_Lander> there is one big bar again
[22:42] <Randomskk> Morseman: so to answer your question, mostly all UTC

[22:42] <Lunar_Lander> saying "30" and "29"
[22:42] <Randomskk> Laurenceb_: hahaha finally
[22:42] <Lunar_Lander> I don't know if that means that it sees satellite 30 with SNR 29
[22:43] <Lunar_Lander> and sometimes it shows two bars
[22:43] <fsphil-laptop> is it near a window Lunar_Lander? it helps if it can see at least some sky
[22:43] <Randomskk> Laurenceb_: but that 6-axis part with accel+gyro and external i2c magno includes state estimation and filtering and fusion in hardware
[22:43] <Lunar_Lander> the window is like 3 m to the left ot me
[22:43] Action: Laurenceb_ reads datasheet
[22:43] <Lunar_Lander> but I think I'll need a longer USB cable
[22:43] <Randomskk> ah looks like this one might too
[22:43] Morseman_ (586125bd@gateway/web/freenode/ip. joined #highaltitude.
[22:43] <Laurenceb_> its itg9150 accel and magno are a bit poor
[22:44] <Morseman_> I timed out for some reason
[22:44] <Randomskk> Morseman: UTC.
[22:44] <Randomskk> the GPS units receive GPS time from the satellites and also the offset to UTC, then apply that offset and output UTC time
[22:45] <Morseman_> Thanks Randomskk
[22:45] <Randomskk> and yes, the two are different - mostly because UTC has leap seconds and GPS time does not

[22:46] <Morseman_> My Trimble Thunderbolt is saying 'Leap second pending'
[22:46] <Randomskk> yea
[22:47] <Randomskk> that means it has not yet received the UTC-GPS offset
[22:47] Morseman (586125bd@gateway/web/freenode/ip. left irc: Ping timeout: 245 seconds
[22:47] <Randomskk> so will be outputting GPS time, or no time
[22:47] <Morseman_> In fact it was the Trimble display that made me realise that the clock was 15 seconds different to the PC, which is kept on time using D4
[22:48] <Morseman_> There's a setting in the Trimble sofware to change it to UTC
[22:48] <Randomskk> curious

[22:49] <Morseman> Tend to only have the Trimble on for its 10MHz GPSDO output to lock the 10GHz receiver
[22:50] <Morseman> Must put an outdoor antenna on the Trimble - a small magmount "puck" on the window ledge doesn't always see enough sats

[22:54] <Lunar_Lander> unfortunately I can't place it near a window right now
[22:55] <Morseman> Plus 36dB would be very good
[22:55] <Morseman> -36dB very poor

[23:12] <Bob_G8NSV> Got to get my little 12v mobile PC rigged up with the FCD for mobile tracking!
[23:13] <Morseman> Bob_G8NSV I'm intending to use an old FT817 that I use for 10 and 24GHz transceivers
[23:14] <Morseman> But was thinking of a notebook powered by 12 to 240V inverter
[23:14] <Bob_G8NSV> I only have motorola FM pmr mobiles and portables
[23:15] <gonzo_> you can get universal 12-switchable dc (15/18/19/24v) for laptops for about £20
[23:15] <Bob_G8NSV> I got a low power MB and one of those a2v PSU's for a project I had a couple of years ago. Should work fine with the FCD
[23:15] <Bob_G8NSV> 12v
[23:16] <fsphil-laptop> those universal supplies don't seem to like 12v. they expect 13.8v
[23:16] <Morseman> I already have the 12V/240V inverter gonzo_ ;-)
[23:16] <gonzo_> whatever you have to hand
[23:16] <gonzo_> np
[23:16] <Bob_G8NSV> will work!
[23:16] <Morseman> Sorry - it's a commercial one so it's probably more like 13.8 than 12V of course
[23:16] <Bob_G8NSV> will use what I have, the FCD is so sensitive
[23:16] <gonzo_> and a handheld gps with lat/lon in the same format as your telem strings is sooooo useful
[23:17] <Bob_G8NSV> load into android phone I hope will work with a gps app I have , will give a "path" type of display to target
[23:17] <Morseman> My old GPS MKIII+ will allow various settings on one of the displays
[23:18] <gonzo_> as it was pitch black when we got to site. Got the telem string in the car, then just walked about the field till the coords matched. Almost walked into it in the dark
[23:18] <Morseman> But the mobile phone seems to be very poor at RX sats at times
[23:18] <Bob_G8NSV> with a good signal the gps should get you to within a few meters

[23:20] <Bob_G8NSV> one of them gives a compas type of display with distance to a lat long you can enter
[23:20] <andrew_apex> A question to anyone tracking the short SHARP flight earlier today - did the frequency issues/jumps seen on monday cause much of an issue? I think saw one, but would people agree it was much better?
[23:21] <Bob_G8NSV> didnt track today
[23:21] <Randomskk> I wasn't around to watch but fldigi managed to keep on going until nearly the end entirely automatically

[23:21] <Bob_G8NSV> never made it above my aos
[23:22] <Bob_G8NSV> picochu drifted a lot and went up and down in sig level anyone else see that?
[23:23] <Morseman> andrew_apex seemed better here as well but I too had to leave it running unattended
[23:24] <Randomskk> Bob_G8NSV: I did notice ups and downs in signal level but probably my poor reception

[23:24] <Morseman> Same here Bob_G8NSV but I was right on the edge of the blue line range
[23:25] <gonzo_> looking at the last received telem, picochu must hav dropped quite quickly at the end to land where it did
[23:25] <gonzo_> would have been interesting if it had of ascended again tomorrow!
[23:26] <Bob_G8NSV> I had a low level due to local terrain but there was a lot of fading on the signal. I have a theory this could be reflections from the foil envelope giving odd lobes in the radiation pattern, would be interesting if someone in the know could model this in nec or similar?
[23:27] <Bob_G8NSV> as the payload spins it changes the levels in different directions?
[23:27] <Bob_G8NSV> payload/envelope spins
[23:29] <mfa298> andrew_apex: I didn't notice anything particularly bad but then I didn't have a good recieving station durign the short flight.
[23:29] <mfa298> Will have to see what happens tomorrow
[23:29] <andrew_apex> step 1: get SHARP out of tree...
[23:30] <mfa298> What do you reckon SHARP's launch time is likely to be ?
[23:30] <mfa298> and do we have an idea of how far it might go tomorrow ?
[23:32] <andrew_apex> mfa298: we hope to launch at 2pm
[23:32] <andrew_apex> and have a 2-3 hour flight
[23:32] <andrew_apex> but it all depends if the tree plays ball with us
[23:34] <mfa298> so actual launch around 4pm as normal then :P
[23:35] <gonzo_> The antenna would not have a particularly omni pattern, so spinning is a probable cause. The balloons were far enough away to have little effect I recon
[23:36] <Bob_G8NSV> morseman yea ham gps lets you anter a gps co-ordinate and gives you a compass rose arrow with distance to target
[23:36] <Morseman> I'm just downloading it onto my phone :-)

[23:40] <Morseman> ASL notoriously in accurate on most GPS units

[23:53] <Lunar_Lander> I just went to the kitchen to eat and left the GPS running
[23:53] <Lunar_Lander> and we got a 3D Fix!
[23:54] <Morseman> 3D seems to work on this
[23:55] <Bob_G8NSV> well I'm going to go for a kip, was up at 5 on fri so a bit knackered. A couple of ciders down the pub has me ready for a snooze!!
[23:55] <Lunar_Lander> and the position it gives is about only say
[23:55] <Lunar_Lander> 30 m away from here
[23:56] <Bob_G8NSV> it seems a useful app prob great for finding payloads!
[23:56] <Lunar_Lander> yea
[23:56] <Lunar_Lander> the altitude changes
[23:56] <Lunar_Lander> as does the position
[23:56] <Lunar_Lander> but it stays in the same ballpark
[23:56] <Lunar_Lander> maybe because the signal levels change
[23:56] <Lunar_Lander> but this is the first GPS I got working!
[23:57] <Lunar_Lander> what is SPS Mode?
[23:57] <Bob_G8NSV> outdoor with loads of sats gives way less error
[23:57] <Lunar_Lander> is that good or bad?
[23:57] <Lunar_Lander> yea
