[00:00] <fsphil> or dominoex, which has lots of frequencies
[00:00] <NigeyS> btw would a cmos sensor from an old webcam run sstv ?
[00:00] <fsphil> should do, if you could get the image data from it
[00:01] <NigeyS> hmm i have a quickcam pro 5000 here thats got a nice sensor, used it on the scope so its already slightly hacked
[00:01] <fsphil> talking to a sensor directly could involve some major mojo though
[00:01] <fsphil> nice camera that
[00:01] <NigeyS> was till it hacked the guts out of it to make it fit in the finderscope..lol
[00:02] <NigeyS> amazing what you can do with a bit of steel tube, super glue, and an old filter case
[00:02] <NigeyS> planetary imager & guidescope in 1
[00:03] <fsphil> excellent
[00:03] <fsphil> yea the dslr is quite poor for planets
[00:03] <NigeyS> beats paying £160 for practically the same thing, baring in mind most guidescopes are 1.3Mp and mono
[00:05] <NigeyS> planets are a pain fullstop, have to use such a short exposure
[00:05] <fsphil> for sstv you'd only need something really simple - the quality isn't going to be all that great
[00:05] <natrium42> fsphil: when are you launching?
[00:05] <NigeyS> well ive left the usb gobbins entact on the logitech board so may have something to work with
[00:06] <fsphil> if you got one of those small linux boards, that has a usb plug. something like the gumstix, which I think jcoxon flew before (and did sstv from)
[00:06] <fsphil> natrium42, weekend after next
[00:06] <NigeyS> i was thinking friendly arm .. i quite like those boards
[00:06] <fsphil> weather permitting
[00:07] <natrium42> ok, hope i am not disappoint
[00:07] <natrium42> :P
[00:08] <NigeyS> natrium42, when are you visiting this lovely little island of ours ?
[00:08] <fsphil> *everything* will work perfectly :D
[00:08] <natrium42> NigeyS: may 14-16
[00:08] <NigeyS> now uncross your toes phil :P
[00:08] <natrium42> haha
[00:08] <natrium42> how do i dress to england?
[00:08] <natrium42> business casual?
[00:08] <fsphil> waterproof
[00:08] <natrium42> lol
[00:09] <NigeyS> haha yeah wellies and wool m8
[00:09] <natrium42> what the hell is a wellie?
[00:09] <NigeyS> wellington boots!

[00:10] <natrium42> is this customary?
[00:10] <NigeyS> pretty normal for a british summer.. flooding.. snow .. hail..sleet..
[00:10] <natrium42> j/k guys, i have been to england before :P
[00:10] <fsphil> it's either a drought, or floods :)
[00:10] <NigeyS> or if ure really lucky .. both ;)
[00:11] <fsphil> london's a neat place
[00:11] <natrium42> i need to learn some vocab first, i think...

[00:12] <fsphil> but I've never learned the art of stopping a taxi
[00:12] <NigeyS> e
[00:12] <NigeyS> ahh phil, you have to jump out in front of it
[00:12] <NigeyS> if its free you get in, if not you get a week in a nice cosy bed courtesy of the nhs :D
[00:13] <natrium42> bollocks!
[00:13] <NigeyS> lol
[00:13] <natrium42> i'll prolly need a brolly
[00:13] <fsphil> I've also learned that "around the corner" in a city means "five miles away"

[00:23] <NigelMoby> Nah we say it here to

[06:41] <natrium42> nah, i got it out of the mailing list :D
[06:49] <Dan-K2VOL> ahh gotcha

[07:05] <Dan-K2VOL> ugh Nigel
[07:06] <Dan-K2VOL> every time we look at this thing there's a new problem wrong with it
[07:06] <Dan-K2VOL> the 5v problem came up again
[07:06] <NigelMoby> Ooo that's no fun
[07:07] <Dan-K2VOL> and when trying to ground the payload internal support frame (which won't take solder for some reason) we scattered wire brush fibers all over all the PCBs
[07:09] <NigelMoby> Oh just to keep you on ure toes eh lol
[07:09] <Dan-K2VOL> indeed, tweeted a pic of all the recovered fibers on a magnet
[07:10] <NigelMoby> Aha magnets are useful!!
[07:13] <NigelMoby> That 5v issue seems odd mind. Intermittent problems like that are the worst kind to troubleshoot

[07:30] <Dan-K2VOL> nigelmoby we traced it to only happening when the cutdown is connected during poweron
[07:30] <Dan-K2VOL> when on ground power supply
[07:30] <Dan-K2VOL> you can connect the cutdown after poweron, and it's fine
[07:30] <NigelMoby> How weird

[07:42] <Dan-K2VOL> oh hey that actually looks cool
[07:42] <natrium42> it was released friday
[07:42] <natrium42> :)
[07:43] <Dan-K2VOL> A little unconventional with the terming of the in-app purchase as "unlocked version" though
[07:43] <Dan-K2VOL> but I'm downloading it now!
[07:44] <Dan-K2VOL> YOu should suggest to him to change that wordage to something like "Pro Features"
[07:44] <Dan-K2VOL> nice HAL eye
[07:44] <NigelMoby> Dam my coffee cup must have a hole in it
[07:44] <natrium42> Dan-K2VOL: might be confusing though
[07:45] <Dan-K2VOL> hahah sorry to hear that
[07:45] <natrium42> as the free version is just limited to 15 seconds
[07:45] <Dan-K2VOL> yeah
[07:45] <NigelMoby> Looks a good app that
[07:45] <Dan-K2VOL> maybe Full Features, or somthing. I'm not sure, the unlocked wording just sounds a little odd on the iphone, I've never run into an app that used that that I can recall
[07:46] <NigelMoby> Like the rolling shutter correction
[07:52] <natrium42> ok, i will forward it to my brother
[07:52] <natrium42> :)
[07:52] <Dan-K2VOL> looking cool using it now
[07:54] <natrium42> maybe Full Version?
[07:54] <Dan-K2VOL> that's goodf

[08:45] <natrium42> russian satellites seem to prefer them over dish antenas
[08:46] <natrium42> sorry to disappoint!
[08:46] <Dan-K2VOL> haha
[08:46] <Dan-K2VOL> oh well in space, that will give you circular polarization

[08:55] <natrium42> best if you ask uk people

[10:32] <mattltm> Nope. Im at work :(
[10:32] <MrCraig> :-( sorry mattltm
[10:32] <MrCraig> if it makes you feel any better I'm kicking back in a costa
[10:32] <mattltm> Got called in and now Im missing a course day :(
[10:32] <mattltm> MrCraig: Thanks.
[10:32] <MrCraig> oh no, that is bad
[10:33] <MrCraig> had no idea :-/ work should not be permitted to interfere with ham or habbing. It should be law
[10:33] <mattltm> lol.I agree.
[10:34] <MrCraig> I finished work for a couple of weeks yesterday - had to do three days work in one day to clear my todo list - and I just know the two weeks will pass far too quickly
[10:36] <NigeyS> do b doo
[10:37] <mattltm> Going anywhere nice?Or just having a break?
[10:37] <mattltm> Hi NigeyS
[10:37] <NigeyS> hey matt!
[10:37] <NigeyS> hey MrCraig
[10:37] <NigeyS> fsphil, good film, but to short, only 45 mins long :(
[10:38] <MrCraig> Hey NigeyS
[10:38] <MrCraig> i'm going to visit my parents in cov for two weeks mattltm
[10:39] <mattltm> Cool.
[10:39] <MrCraig> Driving up there after meeting with a friend who will be the backup car on launch day. Looking all pretentious in costa
[10:40] <mattltm> lol. I can't even get a cup of coffee today. Our cafe is closed :(
[10:40] <MrCraig> suckage
[10:41] <MrCraig> hab question: Does an ipad digiflidgy exist?
[10:41] <mattltm> On the +side, I do have an Arduino here with me and ive just got the pan and tilt platform working with it :0
[10:42] <MrCraig> ahhh so it's not all bad, some habbing at work lol
[10:42] <mattltm> Yup :)
[10:43] <MrCraig> I miss the days when I had quiet "grave-yard" shifts, I used to write program code on my laptop in the office. The pay sucked though.
[10:43] <mattltm> Im only here babysitting the sparkies
[10:43] <MrCraig> Wrote my most successful product there
[10:43] <MrCraig> aah - yeah, those sparkies have to be watched
[10:44] <MrCraig> The friend I'm waiting on is on an out of hours support call :-/
[10:47] <MrCraig> Carputer not working again - should really fix it propperly so bought a suitable device to hack and tomorrow I'll have the interior of the car apart again. I just wish I had it for the drive.
[10:47] <mattltm> MrCraig: Im an expensive babysitter but they are playing with the Data Centre power so I don't trust anyone else to watch them!
[10:48] <MrCraig> No fair point - I'd have gone in on a weekend to watch anyone messing around in my server room when I was an I.T. dude - and that was only a handful of servers.

[11:00] <MrCraig> Actually, I need to learn eagle and how to convert he output to g-code I can run on the mill. I deemed it too much learning to fit in with my schedule on launch 1
[11:00] <Shuffty> lol
[11:00] <MrCraig> So I freestyled on a breadboard and copied it to protoboard

[11:03] <hibby> Shuffty: eagle's nae fun :(
[11:03] <Shuffty> no worries - I'm looking after my youngest while the wife works and watching the motogp qualifying :-)
[11:03] <Shuffty> Eagle seems to be pretty simple to use....
[11:04] <MrCraig> I found a package called Target 3001! (exclaimation as part of the name - cheeeese) it actually seemed really good and has a lite edition for free
[11:04] <MrCraig> it autoroutes and even produces a 3d rendering of the finished board
[11:05] <Shuffty> Not sure about the 3d rendering, but eagle does autoroute...
[11:05] <Shuffty> ..and it's only$125 - I might buy it if I start using it a little more.
[11:06] <MrCraig> eagle is $125?
[11:06] <hibby> there'll be f/oss options for less
[11:06] <hibby> generally what I try to use, the university appreciate it. 7
[11:08] <Shuffty> Yeah - $125 if your working on stuff thats not for profit... in other words - as soon as whatever it is you work on makes money - you have to buy it :-)
[11:09] Action: hibby does what he normally does then and pulls out the academic card
[11:10] <hibby> "look at what the cool things this program y'all wrote is doing :)"

[11:15] <jackwardell> If I use the Lassen iQ GPS module in a balloon, how do I communicate with myself on Earth?
[11:16] <hibby> low power radio
[11:17] <jackwardell> Is that the cheapest option?
[11:17] <TangoAlpha> i'm currently testing one of these http://www.radiometrix.com/content/ntx2
[11:17] <TangoAlpha> and one of these http://www.radiometrix.com/content/nrx2
[11:17] <hibby> well you could log all the data and read it upon retrieval of the payload, but it's not particularly ideal.
[11:18] <hibby> i've got an ntx 2 kicking about, and another module from RS, and some (really cheap) ones from maplin I might try as a backup/alternate to see how effective they are
[11:18] <SpeedEvil> ntx2 + cheap GPS + micro + veroboard + bats.
[11:18] <SpeedEvil> Is about the cheapest sane.
[11:19] <jackwardell> Could I communicate by SMS?
[11:19] <SpeedEvil> You can also use phones with brken screens if you want to od that
[11:19] <SpeedEvil> SMS is unreliable on the ground (actually lying on the ground) in random orientations.
[11:19] <hibby> it's potentially unlegal to do SMS at altitude
[11:19] <SpeedEvil> SMS also may not work above a few hundred meters (or even less)
[11:20] <SpeedEvil> The cell-towers are designed as much as possible to put no signal into the air, as it robs them of range.
[11:21] <jackwardell> Hmmm... What is the cheapest easiest way of precisely communicating with the payload when it's on the ground?
[11:21] <jackwardell> (when it's landed)
[11:22] <hibby> of the three groups i'm working with, the most impressive is the module they've bought that you stick a SIM card in, text it and it returns you the gps data
[11:22] <hibby> can phone it and hear what's going on too :)
[11:22] <SpeedEvil> hibby: Great - if it works.
[11:22] m1x10 (m1x10@ppp046176119071.dsl.hol.gr) left irc: Remote host closed the connection
[11:23] <hibby> another group are using a phone with an app that will post the locations onto a map
[11:23] <SpeedEvil> jackwardell: For total outlay - a SMS tracker of some form.
[11:23] <hibby> another group (actually) used a rape alarm and the goodwill of the local people
[11:23] <SpeedEvil> jackwardell: But that comes with a substantial risk of losing the payload.
[11:24] <SpeedEvil> jackwardell: The current tendancy is to chase the balloon - aided by online predictions - in a car. This easily gets you to within a few miles of where it's coming down.
[11:24] <SpeedEvil> This means that it's at maybe 1000-2000m altitude at worst.
[11:25] <SpeedEvil> 1000-2000m altitude, and typical descent rates mean your search area is only a few hundred meters in diameter.
[11:25] <jackwardell> Ahhh, see I don't want to lose it. I'm not cashing out and then losing it. So let me get this right, I need a GPS module connected to a radio transmitter? And I need a receiver?
[11:25] <SpeedEvil> yes.
[11:25] <SpeedEvil> And the radio can easily be picked up from a few hundred meters.
[11:25] <fsphil> and a microcontroller to take the gps data and control the radio
[11:26] <SpeedEvil> The tracker also means that up to a dozen or so people can assist by turning ont heir radios, and uploading strings they recieve to a central location.
[11:26] <jackwardell> Thanks guys, now considering I'm no pro at electronics and programming (I'm learning). Is the GPS/radio transmitter easy to programme?
[11:26] m1x10 (m1x10@ppp046176119071.dsl.hol.gr) joined #highaltitude.
[11:27] <fsphil> there are some really good examples online
[11:27] <fsphil> plus it's a fine way to learn about this stuff :)
[11:27] <SpeedEvil> jackwardell: Mostr of it can be exhaustively tested on the ground.
[11:28] <SpeedEvil> http://spacenear.us/tracker/
[11:28] <jackwardell> The radio receiver, how much is that? Are they expensive?
[11:28] <SpeedEvil> This is the tracker - everyone who recieves your signal can automatically upload to it
[11:29] <SpeedEvil> at the moment, someone is just testing.
[11:29] <fsphil> which reminds me, I should be testing the hadie payload shortly so it should appear on the tracker
[11:29] <SpeedEvil> radio isn't cheap unfortunately, ebay is the best source.
[11:29] <fsphil> assuming the gps works ;)
[11:30] <SpeedEvil> However, they do hold their value well, so can be resold if you want.
[11:30] <SpeedEvil> I forget the model numbers
[11:30] <TangoAlpha> i'm using an nrx2 attached to an arduino mega for receiving.
[11:31] <TangoAlpha> radio in, gps out :-)
[11:31] <SpeedEvil> TangoAlpha: Many modular receivers are some orders of magnitude less sensitivre/more noisy than a 'proper' radio.
[11:31] <TangoAlpha> i will be testing it in the next few days
[11:31] <jackwardell> So wait, the NTX2 has a range of 500m, surely its hard to track?
[11:31] <SpeedEvil> For example, we regularly get 400km+ on some.
[11:32] <SpeedEvil> with an ntx2 and a SSB radio.
[11:32] <TangoAlpha> i've got it attached to a YAGI
[11:32] <SpeedEvil> I think the record is 557.
[11:32] <hibby> jackwardell: only has that range in some situations
[11:32] <TangoAlpha> works over a range of 20cm quite nicely, lol
[11:32] <TangoAlpha> oops, just measured and it's actually 40cm
[11:34] <jackwardell> When the balloon is like 20km off the ground, can you still get an estimated Lat,Long&Alt from it?
[11:37] <hibby> even when it's 30km :)
[11:41] <hibby> we've finally settled on the name for our HAB experiments in the university...

[12:58] <NigeyS> lol hibby
[12:58] <jcoxon> hi jackwardell , apologies or not replying to your email

[12:59] <hibby> speak later

[12:59] <jackwardell> That is fine, after finding #highaltitude, everything is fine.
[12:59] <jcoxon> jackwardell, so for flights i really recommend going for the low power radio option as your main comms
[12:59] <jcoxon> and then perhaps sms cellphone as backup
[13:01] <jackwardell> Would I use something like Yaesu FT-790R as my radio receiver?
[13:01] <jcoxon> yes
[13:01] <jcoxon> and you'd use the collective radios of all the people listening

[13:07] <NigeyS> what do we win ?
[13:08] <mattltm> Virtual cake.
[13:08] <NigeyS> cake works for me!
[13:08] <mattltm> Is is normal for the alt to spike like that?

[13:09] <NigeyS> i think the alt on gps can be 1 of the lesser accurate measurements
[13:10] <mattltm> Athough I guess that +/-2m is not all that at 30Km!
[13:10] <NigeyS> slightly insignifficant
[13:11] <Laurenceb> gps wobbles about a lot
[13:11] <Laurenceb> what receiver?
[13:11] <mattltm> Venus
[13:11] <mattltm> The position is good.
[13:11] <Laurenceb> ah
[13:11] <Laurenceb> it.. works
[13:11] <Laurenceb> aiui its not the best
[13:11] <mattltm> about 3M out based on spacenear.
[13:11] <Laurenceb> thats pretty good for GPS
[13:12] <mattltm> The correct posittion is 2M S/E of where the trampoline is/was.

[13:17] <Laurenceb> run for?
[13:17] <NigeyS> his payload on a 9v batt
[13:20] <mattltm> I have an Arduino, Venis GPS, Active GPS antenna, NTX2 and an LED being powered from a single 9V battery....
[13:20] <mattltm> How long will it last?

[13:24] <mattltm> Good job jcoxon
[13:28] Action: jcoxon has got quite good with interfacing non dl-fldigi flights with spacenear.us

[13:29] <jonsowman> good work
[13:30] <jcoxon> ooooo i've got an idea
[13:31] <jcoxon> that flight path might get interrupted
[13:34] <jackwardell> Hypothetically, if I were to use a GPS SMS tracker, I sent a text and it was above 60,000ft, so it couldn't reply, then if I text it again once it landed, would it work?
[13:35] <jcoxon> yes
[13:35] <jcoxon> depends a little on the actual device
[13:35] <SpeedEvil> Some GPSs requrie a power cycle on exceeding the limits

[13:44] <mattltm> Running for 1:43. Starting to get blips in the rtty. A sign that it's running low.
[13:44] <jcoxon> i can't push it too quickly
[13:44] <SpeedEvil> jcoxon: neat
[13:44] <jcoxon> so 5second gaps between
[13:44] <jcoxon> then once we've caught up i'll switch to my regular script

[13:48] <NigeyS> its dying matt :(
[13:48] <jcoxon> as i'm using just the time i process teh data - i actually have no time data for their flight as they don't give it in the kml file i'm ripping the data from

[14:24] <fsphil> I've a feeling we won't find out
[14:24] <jcoxon> they certainly have poor public outreach
[14:25] <fsphil> I wonder if it's part of the deal -- maybe they had to sign an NDA
[14:25] <jcoxon> maybe but then its a bit cheeky to ask for hams to listen out

[14:29] <jgrahamc> Where are you launching from stilldavid?
[14:30] <stilldavid> jcoxon: unfortunately, no :( didn't get it working in time
[14:30] <stilldavid> jgrahamc: Colorado, USA
[14:30] <jcoxon> how you tracking?
[14:30] <stilldavid> ntx2
[14:30] <jcoxon> dl-fldigi?
[14:30] <stilldavid> will have a spot on it as well
[14:31] <stilldavid> yeah, dl-fldigi. unfortunately there's little/no cell coverage where we track, so uploads are sketchy at best
[14:31] <jcoxon> do you want an xml for your flight?
[14:32] <stilldavid> sure?
[14:32] SpikeUK_ (~chatzilla@pdpc/supporter/monthlybyte/spikeuk) joined #highaltitude.
[14:32] <jcoxon> as in with dl-fldigi/spacenear.us you need an xml on the server so it can interpret your strings
[14:32] <jcoxon> also if you email the GPSL list i reckon you could recruit some more listeners
[14:32] <NigeyS> hmm anyone .. got a 3.3vreg but its spitting out 3.7 with a 10uf cap
[14:32] <stilldavid> oh, no then.
[14:33] <stilldavid> jcoxon: you think?
[14:33] <jcoxon> yeah
[14:33] <jcoxon> stilldavid, so our max range has been 555km
[14:33] <stilldavid> eh, not sure I want to bother with such little lime left. hoping for an 11am local time launch, so 2.5 hours or so
[14:33] <jcoxon> so you might be able to get another local ham in the area tracking

[14:34] <jcoxon> stilldavid, if you give me a example telem string i'll set it up as well
[14:34] <jcoxon> no harm in getting it ready
[14:34] <stilldavid> okay, cool. hold a sec.
[14:35] <jcoxon> then if someone does think to listen then its not problem for them
[14:35] <jcoxon> also with an xml dl-fldigi will put lat/lon in the right place on the display boxes
[14:36] <stilldavid> ack, I don't have a sample on this box. you going to be around in an hour or so?
[14:36] <jcoxon> sure
[14:36] <jcoxon> don't need a wav
[14:36] <jcoxon> just the format
[14:37] <stilldavid> cool. will do that first thing. I have the format, but I'd like a "real" sample string from the payload, which I have on my other machine
[14:37] <jcoxon> cool cool
[14:37] Action: stilldavid needs more dropbox in his life
[14:37] <jcoxon> don't let me get in the way though
[14:37] <jcoxon> if you run out of time don't worry
[14:37] <jcoxon> just with the low power radios the more listeners the better even if its just 1 more person
[14:38] <stilldavid> it's pretty well put together at this point, just going through checklists and whatnot.

[14:40] <Lunar_Lander> hello jcoxon m1x10
[14:40] <NigeyS> hi lunar
[14:41] <Lunar_Lander> it's not a nice feeling to be grounded
[14:41] <Lunar_Lander> mail is still anywhere but here
[14:43] <Lunar_Lander> but i finally have a chance to solder something
[14:43] <Lunar_Lander> the one ear part of my earphones came off and a very fine copper wire ripped off its original solder spot
[14:43] <Shuffty> :D
[14:44] <Lunar_Lander> this should be a soldering task with a low risk of screwing up
[14:46] <AL0I_Todd> PBH-14 is still transmitting. It is transmitting CW every 10 min. starting at H+04, so next transmission will be at 1454 UTC (if chase crews don't pick it up). I can barely hear it in NC.
[14:46] <jackwardell> is 430-450MHz a HAM Radio frequency?
[14:47] <Lunar_Lander> why is the website of PBH so crappy?
[14:47] <jcoxon> AL0I_Todd, one the ground i assume
[14:47] <jcoxon> on*
[14:47] <Lunar_Lander> they have no photos/videos, not even real flight recaps
[14:47] <AL0I_Todd> I can't get a full telemetry string, but it has to be by now.
[14:47] <Lunar_Lander> pretty poor for a "semi-professional" thing
[14:48] <Lunar_Lander> I think they are semi-professional if they're backed by Lockheed
[14:51] <fsphil> I wonder when they'll try again
[14:51] <AL0I_Todd> The HF frequency given by the PBH team is carrier frequency, so tune appropriately for your rig.
[14:51] <jcoxon> AL0I_Todd, you going to listen out for the Pell City WB8ELK launch?
[14:52] <AL0I_Todd> Maybe. It's probably a waste of time for me. I'm too close for skip and too far for line-of-sight.
[14:52] <fsphil> How far?
[14:53] <Lunar_Lander> hi fsphil btw
[14:53] <fsphil> hiya lunar!
[14:53] <AL0I_Todd> I'm in NW NC.
[14:53] <Lunar_Lander> do you agree with the PBH website being crappy?
[14:53] <AL0I_Todd> It leaves much to be desired.
[14:53] <fsphil> it's a bit ... spacious :)
[14:54] <jcoxon> Lunar_Lander, i've made it so that pbh data is plotted on spacenear.us
[14:54] <AL0I_Todd> PBH-14 transmitting now
[14:54] <fsphil> HF is pretty weird, so it's always worth a try
[14:54] <Lunar_Lander> cool!
[14:54] <Lunar_Lander> but still
[14:54] <jcoxon> to aid in your following of the flight
[14:54] <Lunar_Lander> no recaps, no photos
[14:54] <fsphil> morse code is an odd choice too

[14:55] <fsphil> that's a fun mode!
[14:55] <fsphil> if I've time I'll try that on hadie3
[14:55] <Lunar_Lander> so that also works with NTX2?
[14:55] <fsphil> yep!
[14:56] <Lunar_Lander> ah
[14:56] <Lunar_Lander> wiki says that it transmits a picture or so
[14:56] <fsphil> it's an on/off mode, a bit like morse
[14:56] <fsphil> basically yea, it's decoding as an image
[14:56] <fsphil> a very narrow continuous image
[14:57] <Lunar_Lander> ah
[14:57] <Lunar_Lander> like black pixel/white pixel
[14:57] <fsphil> yea
[14:57] <Lunar_Lander> cool
[14:57] <fsphil> but with the ntx2 there'll be two versions, one the negative of the other

[15:51] <jcoxon> pong stilldavid
[15:51] <stilldavid> https://gist.github.com/899597
[15:51] <stilldavid> a few sentences from yesterday
[15:52] <stilldavid> call, count, time, lat, lon, alt, speed, course, temp
[15:52] <jcoxon> rtty?
[15:52] <jcoxon> freq?
[15:52] <stilldavid> no decimal points, of course
[15:52] <stilldavid> yeah, rtty, 434.650 50 bps 425 shift
[15:53] <jcoxon> ascii-8?
[15:53] <stilldavid> you got it
[15:53] <stilldavid> I set it to two stop bits and that works a treat
[15:54] <stilldavid> might be pushing noon, local time :)
[15:54] <stilldavid> cannot find the car adapter for the ft-817
[15:56] <jcoxon> stilldavid, does your checksum include the $$?
[15:57] <jcoxon> stilldavid, oh i see
[15:57] <jcoxon> thats a XOR checksum but padded to 4
[15:58] <stilldavid> yes
[15:58] <jcoxon> hmmm that might be a bit harder to fix
[15:58] <jcoxon> why pad it?
[15:59] <stilldavid> no worries.
[15:59] <stilldavid> I have a script that does it locally
[15:59] <jcoxon> just means that dl-fldigi/spacenear.us is going to cry
[16:00] <stilldavid> ah, understood.
[16:00] <stilldavid> don't worry about it
[16:00] <jcoxon> as it works on the assumption that 4 checksum chars = crc16 and 2 checksum chars = XOR
[16:01] <stilldavid> crap, actually not sure where the extra 00 is coming from
[16:01] <stilldavid> hold
[16:01] <jcoxon> ping Randomskk jonsowman DanielRichman
[16:01] <DanielRichman> hi jcoxon
[16:02] <stilldavid> jcoxon, you know, it works locally. I don't want to touch the code an hour before flight. I'll give you plenty of notice next time :)
[16:03] <jcoxon> DanielRichman, is habitat in a position to do some custom parsing for stilldavid?
[16:03] <jcoxon> stilldavid, completely agree
[16:03] <DanielRichman> jcoxon: I think one of jonsowman Randomskk or natrium42 might be able to get it to work on spacenear.us...
[16:03] <DanielRichman> habitat could do it
[16:04] <DanielRichman> I don't know how well :P
[16:04] <jonsowman> hi jcoxon
[16:04] <jcoxon> stilldavid, leave it with us - if it works it works...
[16:04] <jcoxon> you focus on a launch
[16:04] <DanielRichman> Randomskk wrote a message sink that pushes parsed data from habitat to habhub.org/tracker
[16:04] <DanielRichman> (which is totally awesome)
[16:04] <stilldavid> oh, I don't want to cause a ruckus.
[16:04] <DanielRichman> so we might be able ot get it to put the track on there
[16:04] <DanielRichman> stilldavid: well I'm going to try and get habitat to do it since we're now at a point where we want to start testing it with real data ;)
[16:05] <stilldavid> if you do, shoot an email to gpsl on my behalf. aiming for noon launch (T -2h)
[16:05] <jcoxon> DanielRichman, https://gist.github.com/899597
[16:05] <jcoxon> example string
[16:05] <jcoxon> s
[16:05] <DanielRichman> rjh's dl-server will forward data to habitat; what time is the launch GMT?
[16:05] <stilldavid> the spot link will be here: http://share.findmespot.com/shared/faces/viewspots.jsp?glId=0VSOSac1275Xczm05gSxTBEcJcPoAf6Ix
[16:05] <stilldavid> 6pm gmt
[16:05] <jcoxon> stilldavid, oooo we can pull and post spot if you want
[16:05] <DanielRichman> today?
[16:05] <jcoxon> though it'll cut out at 18km
[16:06] <stilldavid> yeah, and I've heard they have issues resetting, but eh. it's an experiment :)
[16:06] <stilldavid> brb
[16:06] <fsphil> haha
[16:06] <DanielRichman> jcoxon: what's the name of stilldavid's project?
[16:06] <jcoxon> KI6YMZ
[16:06] <jcoxon> thats his call
[16:07] <fsphil> we should make the checksum indicator configurable ... could have set it to "*00"
[16:07] <DanielRichman> does it have a friendly name?
[16:07] <fsphil> would also have been a neater solution to tim's baudot issue

[16:17] <Lunar_Lander> NigeyS what happened?
[16:17] <stilldavid> so 40.0XXX and -105.2XXX
[16:18] <jcoxon> yeah got that, altitude and time though

[22:47] <Dan-K2VOL> night
[22:47] <Dan-K2VOL> the antennas continue to fail here
[22:48] <mattltm> Did you try a crossed dipole Dan?
[22:51] <Laurenceb> its unresponsive as well
[22:51] <Dan-K2VOL> no, i'm having ham help issues as well, wasting time on J-poles
[22:52] <mattltm> Go for the crossed dipole. Quick to build and designed for sat communication.
[22:53] <Dan-K2VOL> without a ground plane?
[22:53] <mattltm> Sure, Why not?
[22:53] <mattltm> Mine still recived WX sats without a GP.
[22:53] <Dan-K2VOL> why not because I don't know what it neefds
[22:54] <Dan-K2VOL> that's good to hear
[22:54] <mattltm> Here is a good, simple build...
[22:54] <mattltm> http://www.west.net/~jay/turnstile.html
[22:54] <Dan-K2VOL> A vertical dipole doesn't receive well enough, what does the turnstile give over that?
[22:54] <mattltm> Circular polorisation.
[22:55] <Dan-K2VOL> well that will help
[22:56] <mattltm> I have no idea how your payload is configured but maybe you could hang a reflector under it?
[22:56] <mattltm> About 24" lower that the crosed dipole
[22:57] <mattltm> You have to be carefull with using an antenna with too much gain.
[22:57] <fsphil> where you able to test everything else? the modem and coax?
[22:57] <Dan-K2VOL> the whole setup must weigh less than 150g as well, which is why we're trying to abvoid ground planes and radials
[22:57] <Dan-K2VOL> yes, coax and modem are just fine

[22:57] <Dan-K2VOL> they receive perfect horizon to horizon using a 5/8 wave whip mag mount on a car
[22:57] <Dan-K2VOL> that Digi provided with the modem
[22:58] <mattltm> Dan-K2VOL, how did the j-pole get on?
[22:58] <Dan-K2VOL> horrible
[22:59] <Dan-K2VOL> didn't receive any beacon lock at all
[22:59] <mattltm> Maybe try a stacked J-pole for a bit more gain?
[22:59] <Dan-K2VOL> while the whip ran along on our backup sat modem picking it up just fine
[22:59] <mattltm> Here is another example for a crossed dipole with no GP..
[22:59] <mattltm> http://ea4eoz.ure.es/tt.html
[23:01] <fsphil> I'm just baffled why the 1/4 didn't work .. it should be ideal
[23:02] <Dan-K2VOL> says the turnstile is vertical polarization BTW
[23:02] <mattltm> Yes, that is strange.
[23:02] <Dan-K2VOL> sorry fellas I'm just in a bad mood here, this shit isn't rocket science, and it's completely killing our chance to ever get across
[23:02] <mattltm> Dan-K2VOL, its circular.
[23:02] <fsphil> have you tried the 1/4 using the car as a ground plane?
[23:02] <Dan-K2VOL> well mattltm you should forward a correction to the guy who wrote this article: http://ea4eoz.ure.es/tt.html
[23:03] <mattltm> Sure, will do :)
[23:03] <Dan-K2VOL> brb
[23:04] <fsphil> RF is the work of the devil!
[23:04] <mattltm> Yup :)
[23:04] <fsphil> my back garden is littered with the remains of antennas :)
[23:05] <mattltm> This one has been my fave so far...
[23:05] <mattltm> http://www.mattltm.co.uk/2010/11/27/simple-stacked-j-pole-for-2m-70cm/
[23:06] <mattltm> The stacked j-pole is great, you can just keep adding sections until you run out of height :)
[23:06] <fsphil> looks bizarre
[23:06] <mattltm> Works very well. You should have a go using your pole :)
[23:07] <mattltm> What freq does Dan's gear use?
[23:07] <fsphil> I think my little co-linear does as good a job as I'll need here :)
[23:08] <fsphil> 137-138 MHz according to google
[23:08] <mattltm> The same as WX sats.
[23:09] <fsphil> something tells me the uplink is elsewhere though
[23:09] <fsphil> "Uplink power of 5W, frequencies between 148 and 150.05 (189 channels), at 2400 bps"
[23:09] <fsphil> http://www.decodesystems.com/orbcomm.html#uplink
[23:11] <mattltm> So 1 antenna with 2 diferent freq?
[23:11] <mattltm> Needs somthing nice and broadband maybe?
[23:11] <fsphil> yea
[23:13] <mattltm> http://www.orbcomm.com/Collateral/Documents/English-US/spec-sheet-qheb.pdf
[23:16] <mattltm> Looking at the range of antennas for the orbcomm, there must be a problem with somthing elase in the system.
[23:18] <fsphil> possibly rfi
[23:18] <mattltm> I mean, they are setting antennas that must work that are 83% efficent compared to a 1/2 wave whip.
[23:18] <fsphil> something oscillating on the downlink frequency maybe
[23:18] <mattltm> SoSounds like it.
[23:19] <mattltm> I wonder if they have tested the whole payload with the orbcomm hooked up to the 5/8 wave.

[23:23] <mattltm> Venus has an unknown altitude limit..
[23:23] <fsphil> Shuffty, old venus won't work above 18km - newer ones apparently will, but I think untested
[23:24] <fsphil> fsa03 definitely works, but needs to be in the right mode (easy enough) and is somewhat fragile
[23:24] <Shuffty> whats everyone using then - you all using the fsa03 - or other..
[23:24] <fsphil> NigeyS, they need to be the same string

[23:32] <NigeyS> they say 4 weeks but allow 5-6
[23:32] <hburger> mattltm, south east, near Eastbourne
[23:32] <hburger> I mean I know its by the sea
[23:32] <NigeyS> oh eck
[23:33] <mattltm> Ta :)
[23:33] <hburger> but using http://habhub.org/predict/#!/uuid=13a3134357a09a6e4b7f88fdc998c12f74770e75
[23:33] <NigeyS> buy a boat while ure at it
[23:33] <hburger> Pretty damn good prediction... mostly going north
[23:33] <hburger> seriously? do you think its risky doing it down here?
[23:34] <NigeyS> you might be ok, just keep checking the predictions, the winds tend to take the balloons eastwards
[23:34] <hburger> Hm, okay. How good are predictions?
[23:34] <fsphil> anything more than 2 days tends to be fairly random
[23:35] <NigeyS> yups
[23:35] <fsphil> below that it gets pretty good
[23:35] <hburger> if i submit the CAA approval
[23:35] <hburger> would I have to have a specific date?
[23:35] <hburger> I mean thats not possible months in advance
[23:35] <fsphil> unfortunately yes
[23:36] <fsphil> you can request a range of dates
[23:36] <NigeyS> yup, and specific launch site co-ordinates iirc
[23:36] <hburger> (iirc?)
[23:36] <NigeyS> sorry .. if i recall correctly
[23:36] Zuph (~bradluyst@69.64.6.69) joined #highaltitude.
[23:36] <NigeyS> zuphster!!!!
[23:37] <fsphil> yea it's one request per site - but you can request a range to cover a couple of weeks
[23:37] <fsphil> or more if you ask nicely
[23:37] <hburger> Sure.
[23:37] <hburger> I'm having trouble finding the request form
[23:38] <mattltm> How many channel crossings have been done?
[23:38] <hburger> could anyone fetch a link please? :)
[23:38] <fsphil> hmm.. copy+paste fail again
[23:39] <fsphil> http://wiki.ukhas.org.uk/general:restrictions_legality
[23:40] <hburger> fab, thanks fsphil
[23:40] <hburger> Btw, how much would a helium tank to ill the balloon cost roughly?
[23:40] <hburger> Are we talking £30 or £70?
[23:40] <fsphil> the higher one :)
[23:41] <fsphil> it varies depending on how heavy the payload weights, and how fast you want it to ascend
[23:42] <hburger> True. I'm thinking under 1kg... and a 600g balloon.
[23:43] <hburger> On the ukhas wiki, it states a basic launch can be £200. Is this true?
[23:43] <hburger> I mean how basic can a launch be?
[23:43] <mattltm> Mobile phone and a bin bag :)
[23:44] <hburger> Balloon - £35. Camera - £100. GPS - £80 (eBay text gps). Parachute - £20. Hand warmers - £5.
[23:44] <fsphil> haha -- yea and that even worked
[23:44] <hburger> technically, is that really all is needed?
[23:44] <fsphil> you can probably do without the hand warmer
[23:44] <fsphil> and get a much cheaper camera
[23:44] <hburger> Haha ;)
[23:45] <fsphil> the helium will be your biggest cost
[23:45] <hburger> Am i missing anything out from there?
[23:45] <hburger> Oh yeah
[23:45] <hburger> helium
[23:45] <hburger> ^Thats the only component I can't figure out a price for.
[23:45] <hburger> And all the loca party shops are clueless when I say I want a tank ;)
[23:45] <fsphil> it's an iffy value because you won't know how much you need until you've got a good idea of your payload weight
[23:46] <fsphil> ain't they just!
[23:46] <hburger> How much does the payload weight affect the helium amount?
[23:46] <fsphil> I love the odd looks you get when you tell then you're only filling one balloon :)
[23:46] <hburger> Hahah :) Oh, and the payload container.
[23:46] <fsphil> heaver payload will cause a slower ascent
[23:47] <fsphil> but a slower ascent will mean your payload travels a lot further
[23:47] <hburger> Ohh, true.
[23:47] <fsphil> living on an island nation that is not ideal :)
[23:47] <hburger> (Btw, what do you think bout this as a payload container - http://www.stormguard.co.uk/products/Others/more_images/TAPCOVER.htm )
[23:47] <fsphil> so you'd use more helium to make it ascend quicker
[23:47] <hburger> made to prevent taps freezing in winter. It seems like the perfect thing.
[23:48] <hburger> More helium would also mean a lower burting alitutde though?
[23:48] <hburger> *bursting altitude. sorry.
[23:48] <fsphil> indeed
[23:49] <hburger> Hm. So the lighter the better, ey?
[23:49] <fsphil> definitely
[23:49] <fsphil> my last payload was 510g
[23:49] <hburger> What do you think about the stormguard tap cover as a container?
[23:49] <fsphil> could be good - might be a bit on the small side
[23:49] <hburger> Oh wow, that's light. What did you have in it? I mean, GPS wise and camera.
[23:50] <fsphil> basic canon camera, fsa03 gps module and a few circuits and batteries
[23:50] <fsphil> all in a polystyrene box
[23:51] <hburger> (16cm by 15cm. Is that small compared to other paloads?)
[23:51] <fsphil> tis a bit
[23:51] <fsphil> your camera will probably fill that by itself
[23:51] <hburger> How much did our launch cost, fsphil?
[23:51] <hburger> *your
[23:52] <hburger> I mean roughly, sorry if I seemed rude.
[23:52] <fsphil> I didn't count it .. but the materials that actually flew where probably about £250
[23:52] <fsphil> but there where also some ground bits, like the radio receiver, antenna and laptop
[23:52] <hburger> Hm, okay. I don't get the GPS module you used though. How'd it work?
[23:52] <hburger> Im used to the eBay ones which yu send a text to and they text back with coordinates
[23:53] <hburger> or SPOT GPS Tracker (expensive >:( )
[23:53] <fsphil> yea spot would be ideal if it had a better gps and was cheaper
[23:53] <hburger> But that looks entirely different
[23:53] <fsphil> a lot of flights use a small microcontroller to transmit the position over radio during the flight
[23:54] <fsphil> there's a few examples on the wiki -- but I can't copy +paste at the moment
[23:54] <mattltm> hburger, This is a very basic payload - http://www.mattltm.co.uk/2011/03/24/habat-test-payload/
[23:54] <fsphil> using a phone or sms might be cheaper but the success rate has not been great
[23:55] <mattltm> Arduino board, GPS module and low power transmitter.
[23:56] <hburger> Wow - but it looks so complicated...
[23:56] <hburger> About the success rate with the sms, is it really not that good? I mean, how come?
[23:56] <fsphil> taken as a whole it's quite complicated, but each part is actually fairly simple
[23:57] <fsphil> odds are you'll land somewhere without a signal :)
[23:57] <mattltm> Mobile phone masts are designed to put signal out at ground level.
[23:58] <mattltm> hburger, Basic concept of transmitting the data - http://www.mattltm.co.uk/2011/02/18/basic-tracking-transmitter/
[23:58] <fsphil> a radio tracker can be tracked for most of the flight, so even if you loose the signal before it lands you'll know roughtly where it is
[23:58] <hburger> Ah.. I thought something like this seemed too good to be true:
[23:58] <hburger> http://goo.gl/xMbuN
[23:58] <SpeedEvil> They aren't.
[23:58] <SpeedEvil> They're designed to put out signal at head level.
[23:58] <mattltm> lol @ SpeedEvil
[23:58] <hburger> But thats when I'll want the signal - to locate the payload once its on the ground
[23:58] <SpeedEvil> There are _lots_ of blind-spots if the reciever is 10cm over the ground, compared to 2m.
[23:59] <mattltm> Yes, you are right :0
[23:59] <hburger> I getcha...
[23:59] <SpeedEvil> Especially if the orientation is wierd.
[23:59] <fsphil> unless you land in a tree :)
[23:59] <hburger> Haha ;)
[23:59] <mattltm> Ahem, yes lol.
[23:59] <fsphil> happens more than you'd think :)
[23:59] <hburger> And this gps module using arduino - how much does it cost. Honestly, if I had the budget, of course I'd go for it over sms.
