[08:07] <PB0NER> there must be some inversion or so it is extremely loud
[08:07] <PB0NER> my neighbour (80mtrs away) is not getting anything...
[08:07] <PB0NER> on his FCD Pro+
[08:09] <PB0NER> not sure what is wrong on his side (he is remote using teamvieuwer and not@home)
[08:12] <DL1SGP> hard to tell, what frequency did you have B-22 on? pretty precise 434.500?

[08:55] <Steve_G0TDJ> Yeah, I tried for B-21 but it was too far too soon
[08:56] <PB0NER> whan I came from the HAM-club yesterday, I got that last weird message from B-21
[08:56] <PB0NER> and nothing
[08:56] <Andrew_M6GTG> Steve_G0TDJ: I spent last night messing about trying to send APRS messages to the ISS and failed :-)
[08:57] <Steve_G0TDJ> Awwww, is it difficult? I've always thought about having a go at it but not got sorted.
[08:57] <PB0NER> I had no success with that either..
[08:57] <fsphil> I've done it a few times
[08:57] <fsphil> 20 watts managed it
[08:57] <fsphil> in a colinear
[08:58] <Andrew_M6GTG> I managed to get some last week... 4W Baofeng.. none since
[08:58] <PB0NER> getting messages from ISS is no issue
[08:59] <Steve_G0TDJ> Well better luck next time Mate. I@ll have a go at some point
[08:59] <PA3WEG> I managed with the TH-D7 handy
[08:59] <PA3WEG> but you need to get all your settings correct
[08:59] <PA3WEG> mainly use VIA ARISS
[08:59] <PA3WEG> and set your status to something like "committed"
[08:59] <PA3WEG> there are some " rules"
[09:00] <PA3WEG> be sure to check http://www.aprs.org/iss-faq.html
[09:00] <Andrew_M6GTG> PA3WEG: I used the UISS program and a soundcard into my handheld
[09:01] <PA3WEG> ok, no personal experience with that
[09:01] <fsphil> I think it's mainly lucky getting a packet up to the ISS
[09:01] <PA3WEG> but with soundcards, be double sure to check the levels
[09:01] <fsphil> you just have to be transmitting when nobody else is
[09:02] <PA3WEG> that as well ;)

[09:08] <Andrew_M6GTG> DL1SGP: Oh yes very loudly, and transmitting after my tx..
[09:08] <DL1SGP> good :)
[09:08] <Andrew_M6GTG> suspect there wasn't a SatGate in range
[09:09] <DL1SGP> you had no decoding gear for the data it was sending?
[09:09] <PA3WEG> One more thing, if you correct doppler the right way, you might have more chance at the beginning of the pass at the horizon
[09:10] <PA3WEG> so listen on 145.830 and TX at 820

[11:01] <LeoBodnar> 6.3m/s is massive in our terms Steve_G0TDJ

[11:03] <Steve_G0TDJ> For some reason, I thought it would be faster.
[11:03] <gonzo_> the 600bd signal is odd. The Septrumn is strange and afc is not able to follow it here

[12:55] <diegoesep> Oh sorry :) I will talk to him later in that case !
[12:55] <DL1SGP> you can see the car on the map at http://spacenear.us
[12:56] <mfa298> mattbrejza: best guess would be licensing. That's the usual pain with windows and virtualisation.
[12:56] <diegoesep> awesome the car :)
[12:56] <mattbrejza> oh right
[12:56] <DL1SGP> no worries, just telling you so ya do not wonder about not getting immediate reply

[12:57] <GMT> diegoesep: start telling all the hams about the flight, ask for their help in tracking
[12:57] <mattbrejza> or you could just replace osx with windows :P
[12:58] <mfa298> I'm a couple of years out of date now though. But I know licensing is often a pain - especially with corporate licensing as it's technically just an upgrade from the version of windows the machine came with.
[12:58] <diegoesep> yes GMT , I have started to talk about this launch to french neighbours
[12:58] <mattbrejza> either way, jonsowman 's problem :P
[12:58] <mattbrejza> im off to supervise labs
[12:58] <mattbrejza> noone has burnt themselves today :)
[12:59] <diegoesep> but I'm still in design phase for the payload, so it will take more than a couple of months before everything will be ready
[12:59] <DL1SGP> diegoesep: why would you use 144.650 MHz for the APRS ?
[12:59] <diegoesep> because french HAM told me that 144.800 is forbiden for high altitude trackers
[13:00] <DL1SGP> k not knowing about the french rules
[13:00] <diegoesep> they said that some people use it for balloon but that it may completely flood the 144.800 APRS channel too
[13:00] <mfa298> diegoesep: if 144.800 is not permitted for AR use airborne then 144.650 will probably be the same
[13:00] <diegoesep> 144.650 is allowed for balloons
[13:01] <diegoesep> it is reserved for balloons experiments for HAM in France

[13:35] <craag> I don't think that's what you mean...
[13:37] <ve6ts> craag i purchased an RDF system that uses doppler, dopsys.com
[13:37] <ve6ts> where can you get cheap GPS modules? most of the ones i have seen are more then $50
[13:38] Joel_re (~jr@ joined #highaltitude.
[13:39] <craag> Yeah that's not using doppler... that's just phased df arrays.
[13:39] cuddykid (~acudworth@ left irc: Read error: Connection reset by peer
[13:39] <craag> Made by a company called 'Doppler Systems', confusingly.
[13:40] <ve6ts> craag i thought they were the same, well i learnt something :)
[13:41] <craag> Doppler is when the 'viewed' frequency changes according to the relative speed between the observer (your rx) and the object (tx on balloon)
[13:41] PH3V_ (5456e3dc@gateway/web/freenode/ip. joined #highaltitude.
[13:41] <ve6ts> it works very well in the past for balloon tracking, on 1 tracking day i was in someone elses vehcle and i could have used it, we could hear the transmitter (which the RDF has worked fine in the past on) and couldn't decode the packet it would have told us exactly which way to drive
[13:41] <craag> Unfortunately RF crystals exhibit far too much frequency drift for this to be usable.
[13:41] <ve6ts> craag ya that i guess would only work when the speed is much greater as well
[13:42] <craag> well we do have some fast balloons :)
[13:42] <ve6ts> i had one going over 250km/h once

[13:43] <ve6ts> my previous flights were all CW
[13:44] <craag> RTTY makes tracking way easier (lazier)
[13:45] <ve6ts> yes, as logging is easier, for now i'm going to record the transmission and i can decode again later if i want
[13:45] <craag> For GPS modules we get them from: http://ava.upuaut.net/store/index.php?route=product/category&path=59_64
[13:45] <ve6ts> i want to try different modes for fun though
[13:46] <craag> mm, I've been talking to people about building our own MFSK mode, like RTTY but with 4 tones and turbo coding :D
[13:47] <ve6ts> craag just for faster transmission?
[13:47] LA3EQ (55a7fbfa@gateway/web/freenode/ip. joined #highaltitude.
[13:47] <craag> faster transmission, also resistance to burst QRM.
[13:47] <craag> And a lot weaker decoding.

[13:47] <fsphil> that sounds like fun craag
[13:49] <ve6ts> weaker decoding is important, as my signal gets very weak quickly

[13:50] <fsphil> I think fldigi is a bit stricter with tone spacing than it needs to be
[13:50] <fsphil> for domex
[13:50] <fsphil> and thor
[13:50] <craag> mm, but that's probably one of the reasons it decodes so well.

[17:50] <CopyRight> OH7HJ: where are u?
[17:50] <CopyRight> iam in vasa
[17:51] <OH7HJ> Have you heard it to Vasa? I am on http:\\aprs.fi\OH7HJ-1
[17:52] <CopyRight> yes but only in background. I dont have a outside antenna :S
[17:52] <Upu> B-21 is probably going to be asleep until sunrise
[17:53] <OH7HJ> If you hear it indoor it must be pretty near..! Can you tell its exact frequency?
[17:54] <CopyRight> OH7HJ: 1hr back it was in the background. but not now enymore
[17:54] <OH7HJ> Upu, does the B-21 keep totally quiet, or just transmit with longer intervals?
[17:54] <Upu> no the battery is faulty I think
[17:54] <Upu> or the temp has dropped to low for it
[17:55] <Upu> so without solar power won't TX
[17:55] <Upu> http://x-f.lv/dev/habitat-graphs/payload/6288c6fa2028a62a2791aad8c5294b67#g/battery,temperature_internal,solar_panel
[17:55] <CopyRight> alright
[17:55] <OH7HJ> So it probably falls in deep sleep for the night... Well, I will leave the Rx on overnight anyway.
[17:55] <Upu> possibly temp thats doing it
[17:56] <OH7HJ> We are short of solar up here in this time of the year...
[17:57] <CopyRight> yes
[17:57] <CopyRight> and it is raining
[17:57] <OH7HJ> Let's hope that it will be lucky to keep high...
[17:58] <CopyRight> no. let's hope that it's landing at my work :D
[18:00] <ve6ts> that battery sure dropped fast, did it get too cold?
[18:00] <Upu> possibly faulty battery
[18:00] <Upu> B-22 was launched about a few hours after and is fine
[18:00] <OH7HJ> What type battery? Li?
[18:00] <Upu> same hardware
[18:00] <Upu> Lipo I think
[18:01] <Upu> B-22 is over Poland now

[18:02] <OH7HJ> Lipos that I have used have all been very vulnerable to low temps. Below 0 C they lost their voltage. However, as soon as they were warmed to + temps they revived.

[18:08] <LeoBodnar> At room temperature they are pretty much within spec
[18:08] <OH7HJ> There was discussion about doppler direction finding of balloons. Here is one ham rigs adapted doppler DF kit: http://www.silcom.com/~pelican2/PicoDopp/PICODOPP.htm
[18:09] <LeoBodnar> Is it phased array based design?
[18:10] <ve6ts> OH7HJ i bought a commercial RDF tracker
[18:10] <OH7HJ> Yes it is! Need four vertical dipoles in ring, this doppler RDF unit and a regular receiver with FM mode.
[18:11] <OH7HJ> Yes, they all work with the same principle of rapidly switching aerials to make them appear rotate fast.
[18:12] <OH7HJ> When listening to a carrier, it modulates it with aerial switching freq and checks the phase to calculate direction.
[18:13] <LeoBodnar> I have seen a video some time ago where a guy made a presentation on his company making them. as far as i remember it was patented all over
[18:13] <ve6ts> OH7HJ i bought the commercial kit from dopsys.com
[18:14] <OH7HJ> It works well with its omnidirectional 4 dipole array. Limitation is that it is not practical with high gain directive aerials.
[18:14] <LeoBodnar> Might have been even one of the early UKHAS conferences

[18:27] <eroomde> i think radio direction finding is fascinating
[18:28] <eroomde> there exist arrays that can listen to a whole bunch of signals all on the same frequency at once
[18:28] <eroomde> just with spacial multiplexing
[18:28] <eroomde> they can electronically adjust the beam pattern to put a null in the direction of an interfering source, say
[18:29] <eroomde> and in principle you could track many tabs at once all on the same freq if they were in different parts of the sky
[18:29] <eroomde> with 2 such systems, you'd have a great alternative tab locator
[18:29] <eroomde> without the complicated requirement for coherent clocks between separate listening stations
[18:30] <eroomde> the df system will just give you az and al to sub-degree resolution
[18:30] <eroomde> az and el*
[18:30] <SpeedEvil> eroomde: the above is going to be vastly, vastly important for mobviles and wifi in thenext decade
[18:30] <eroomde> yes i think so
[18:30] <eroomde> except it's still cpu internsive
[18:30] Action: bertrik has a book about it, "transmitter hunting, radio direction finding simplified" by J.D. Moell et al.

[18:31] <fsphil> there's a lot of number crunching in those things
[18:31] <eroomde> indeed
[18:31] <eroomde> but they're very pleasing algorithms
[18:31] <Willdude123> Have no clue what to listen for on my NRD 535.
[18:31] <eroomde> with just 8 elements in the array you could track 8 tabs at once and get sub-degree az and el on each of them - how cool is that?
[18:32] <Willdude123> Might take a look at the band plan, or just scan around till I find something
[18:32] <mfa298> I think I'd seen something suggesting that the mobile networks are already starting to use that sort of antenna technology in some places.
[18:32] <fsphil> makes sense
[18:33] <eroomde> the cell towers certainly
[18:33] <fsphil> might work out a good bit cheaper than additional towers
[18:33] det_ (4ff3d058@gateway/web/freenode/ip. left irc: Quit: Page closed
[18:33] <fsphil> and better use of spectrum
[18:33] <fsphil> possibly more secure too?
[18:33] <eroomde> spacial-division multiplexing is jus another dimensions to exploit
[18:33] <mfa298> yes, this was for cell towers.
[18:33] <eroomde> along time frequency and time

[18:34] <fsphil> how dare it
[18:34] <mfa298> Willdude123: the 20m band is often a good place to find activity
[18:34] <eroomde> M6PFX-Paul: yes
[18:34] <eroomde> it's by rome manor
[18:34] <M6PFX-Paul> yeah
[18:34] <eroomde> it was one of their engineers that first turned me on to the technology
[18:34] <eroomde> roke*
[18:35] <M6PFX-Paul> they recently changed their name, but yes Roke
[18:35] <eroomde> cool stuff
[18:35] <mfa298> Willdude123: for 10m you probably need to find the right time of day (propogation on HF will vary during the day - and year, and with sunspots)
[18:35] <eroomde> there needs to be an amateur version!
[18:35] <OH7HJ> Yes, Roke has its Celldar.
[18:36] <M6PFX-Paul> it is, went down there recently but they wouldn't let me take one home :)
[18:36] <OH7HJ> The amateur version of the Celldar is called Aircraft Scatter, AS.

[20:29] <Steve_G0TDJ> Hmmm
[20:29] <Laurenceb_> the best LEDs are like 30% efficient or something
[20:29] <fsphil> fly a retroreflecter

[20:29] <fsphil> only spelled right
[20:29] <Steve_G0TDJ> Whats that fsphil ?
[20:30] <fsphil> retroreflector .. it reflects light back in the direction it came
[20:30] <Steve_G0TDJ> Oh and shoot a laser at it
[20:30] <fsphil> think cats eyes, but on a payload
[20:30] <fsphil> or even just a bright focused LED

[20:37] <Laurenceb_> hmm
[20:38] <Steve_G0TDJ> What about an actual strobe, like a modified flashgun
[20:38] <Laurenceb_> 400Km retroreflector with a 100mW laser would work
[20:38] <fsphil> it's on my list of things to do. which at the frequency I lanuch at, will take a while
[20:38] <LeoBodnar> We have tested our flasher and the range was 2 miles on a overcast day (with binoculars)
[20:38] <Laurenceb_> with a scope for rx it would even do a high data rate
[20:38] <Laurenceb_> a bit naughty as it might hit a plane
[20:38] <LeoBodnar> It runs on 20mAh LiPo for two hours I think
[20:39] <fsphil> if you modulated a green light source quick enough, would you get white light?
[20:39] <Laurenceb_> lol
[20:39] <Laurenceb_> yes...
[20:39] <LeoBodnar> I can donate it if somebody is definitely flying it
[20:39] <Laurenceb_> at ~100Tbps
[20:39] <fsphil> needs thz right?

[20:40] <fsphil> what is it LeoBodnar? just an LED flasher?

[21:22] <ibanezmatt13> What's the very cheapest license you can get to fly without an instructor?
[21:22] LazyLeopard (~irc-clien@chocky.demon.co.uk) joined #highaltitude.
[21:22] <ve6ts> in canada it is called an ultralight pilot permit, and you can fly ultralight planes
[21:23] <ibanezmatt13> everything's a lot cheaper over there though
[21:24] <ve6ts> well it used to be cheaper, but prices are quite high in Canada compaired to the US, they are WAY cheaper

[21:54] <LeoBodnar> Steve_G0TDJ: There is usually a shortage of flying instructors so the trick is to get CPL and get employed as a flying instructor
[21:54] <LeoBodnar> There are very few who stay around
[21:54] <Steve_G0TDJ> I see :-)
[21:55] <LeoBodnar> They are mostly 25-something clocking up flying hours
[21:55] <LeoBodnar> to move into proper commercial aviation
[21:55] <LeoBodnar> so there is a massive personnel rotation in the clubs usually
[21:56] <LeoBodnar> typically you end up having 4-5 instructors by the time you qualify
[21:56] <ibanezmatt13> Do you need a special license to do aerobatics?
[21:56] <LeoBodnar> I'd love to do it again
[21:57] <Steve_G0TDJ> I think if I did it once I'd never want to stop

[22:09] <adamgreig> lead free solder works fine
[22:09] <adamgreig> use a suitable temperature iron

[22:09] <WillTablet> Don't you die of some brain disease?

[22:09] <Steve_G0TDJ> adamgreig: Is that the secret?
[22:09] <adamgreig> if anything lead free solder has a higher VOC content in the air because of the higher temperature so is worse for respiratory problems
[22:10] <adamgreig> Steve_G0TDJ: temperature is definitely the secret
[22:10] <Steve_G0TDJ> When you say suitable temp do you mean high or low?

[22:36] <Laurenceb_> its got tons of stiction
[22:36] <Laurenceb_> any idea how to fix this?
[22:36] G8KNN (~jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginm.net) joined #highaltitude.
[22:36] <Laurenceb_> do you think its feasible with PID?
[22:36] <Laurenceb_> atm its behaving as a sawtooth oscillator?
[22:36] <Laurenceb_> *-?
[22:37] <Laurenceb_> i was kind of thinking about oscillating the control signal around the PID output point
[22:37] <eroomde> what parameter are you trying to control?
[22:37] PH3V (~renetuijt@ip5456e3dc.speed.planet.nl) left irc: Quit: PH3V
[22:37] <Laurenceb_> setpoint is the output pressure
[22:38] <Laurenceb_> the output pressure - theres some leakage back through the pump
[22:38] <Laurenceb_> so i control pwm to the motor
[22:38] <eroomde> hmm
[22:39] <Laurenceb_> or maybe i just need to massivly retune the PID
[22:39] <Laurenceb_> atm its mainly I control
[22:39] <eroomde> either that
[22:39] <Laurenceb_> are very very slow
[22:39] <eroomde> or yeah, your intuition about dithering
[22:39] <Laurenceb_> maybe make the I larger
[22:39] <Laurenceb_> *s/are/and
[22:39] <Laurenceb_> or bang bang control...
[22:40] <Laurenceb_> i dont actually need it to adjust quickly
[22:40] <Laurenceb_> so i set the I really low and didnt use much D and P
[22:40] <Laurenceb_> so its quite stable with some pumps
[22:40] <Laurenceb_> but im doing mass production now, and one pump batch has considerably more stiction
[22:41] <Laurenceb_> and its doing long period oscillation, about 1 minute cycle
[22:41] <eroomde> we use bang bang often
[22:41] <Laurenceb_> pump stops completely then integral ramps up the pwm until it starts and overrevs
[22:41] <eroomde> sometimes it's just good enough
[22:42] <Laurenceb_> i have low noise pressure coming in at 1kHz
[22:42] <Laurenceb_> so i guess that might work
[22:42] <Laurenceb_> i guess ill try large I with zero P and D tomorrow as a first stab
[22:44] <Laurenceb_> ok thanks for the tips :-)

[23:02] <Laurenceb_> yeah i have windup
[23:02] <Laurenceb_> *prevention
[23:02] <LeoBodnar> should work then
[23:03] <Laurenceb_> the current values are pretty guesses
[23:03] <Laurenceb_> it runs nicely with a small air leak
[23:03] <Laurenceb_> but that draws a constant ~50ma
[23:04] <LeoBodnar> call them "feedforward parameters" to avoid questions
[23:04] <LeoBodnar> from reviewers
[23:04] <Laurenceb_> not nice for a battery powered device
[23:04] <Laurenceb_> lol
[23:05] <Laurenceb_> so "feedforward" passes some fraction of the input directly to the output?
[23:06] <LeoBodnar> It's where you have pre-knowledge of the system and force it to a specific state instead of letting it find it on its own
[23:06] <LeoBodnar> I.e. roughly move it where you know it's going to end up and let PID fine-tune it
[23:06] <Laurenceb_> ah
[23:06] <Laurenceb_> that wont work here
[23:07] <Laurenceb_> due to the stiction
[23:07] <Laurenceb_> i have some code to shut it down and restart with the same I value
[23:07] <Laurenceb_> that speeds up the start transient
[23:07] <LeoBodnar> It is usually either empirical or based on some system model, e.g. you know inertia of the motor and you give it fixed kick to bring it back to known speed quickly etc
[23:07] <Laurenceb_> yeah
[23:08] <Laurenceb_> if i had a motor speed sensor this would be easier
[23:08] <Laurenceb_> unfortunately board is done and CE tested...
