[05:56] <heathkid> what are they replacing it with?
[05:57] <heathkid> if someone would do a helical antenna with a SMA connector they'd make a lot of $$$
[05:57] <Spoz> wow I can't believe I only just found this place now, I've been working on a HAB for almost 6 months
[05:57] <heathkid> instead of a board mount
[05:57] <heathkid> Welcome Spoz
[05:57] <Spoz> howdy!
[05:57] <nigelvh> Yes, a SMA helix would be useful
[05:58] <heathkid> so where are they?
[05:58] <nigelvh> Your head
[05:58] <Spoz> I have one in my living room
[05:58] <Spoz> two in fact
[05:58] <heathkid> heh... I'm not winding 'em!
[05:59] <heathkid> Spoz: ???
[05:59] <heathkid> source?
[05:59] <Spoz> my workshop :p
[05:59] <Spoz> crimping an sma is not difficult
[05:59] <nigelvh> Yes, but buying it is even easier.
[05:59] <heathkid> tested?
[06:00] <Spoz> yeah
[06:00] <Spoz> and tuned
[06:00] <Spoz> less than 1% return loss
[06:00] <heathkid> how much? In quantity?
[06:00] <Spoz> no, I built one for 915MHz and one for 1200MHz
[06:01] <Spoz> I'll take a photo
[06:01] <heathkid> oh
[06:01] <heathkid> I'd like to see a photo
[06:02] <nigelvh> Likewise
[06:03] <nigelvh> Meanwhile, I found out that the plastic covering on a AA battery weighs 0.2 grams.
[06:03] <Spoz> http://www.balloon.theredpaintings.com/antennae.jpg
[06:04] <nigelvh> 404
[06:04] <heathkid> same here
[06:04] <Spoz> weird, remove the /balloon/ right before the /antennae.jpg
[06:04] <Spoz> Im not sure why the server adds that
[06:04] <heathkid> nigelvh: a regular AA or a lithium?
[06:05] <heathkid> is there a difference?
[06:05] <nigelvh> This was one of the lithium AAs, but I imagine it's going to be similar on any cell
[06:05] <nigelvh> Also, this are a little large for antennas on a balloon...
[06:05] <nigelvh> these*
[06:05] <Spoz> thats the ground antennas
[06:05] <Spoz> I have skew planars for the balloon
[06:05] <nigelvh> Yes, I'm sure they make good ground antennas
[06:06] <heathkid> so would a PTZ Yagi
[06:06] <Spoz> you meant helical balloon antennas? it would take some work to keep them oriented correctly
[06:06] <nigelvh> I used to have a similar one for 1.2G, but gave it to another ATV guy locally.
[06:07] <heathkid> or should I say a controlled Alt/Az Yagi
[06:07] <heathkid> so it knows where to point
[06:07] <nigelvh> Yeah, I'm pretty certain heath kid was hoping for an antenna for on the balloon as a replacement for the board edge mount helixs
[06:07] <nigelvh> helixes*
[06:07] <heathkid> yep
[06:07] <Spoz> unfortunately we don't have an automatic tracker, so thats going to be interesting
[06:07] <heathkid> We're working on it

[06:09] <nigelvh> I've seen small helixes made up for the various sondes that the weather services do
[06:10] <Spoz> hm
[06:11] <heathkid> eh... at this point I'm not sure for a HAB that a chip antenna wouldn't work just as well and is cheaper and a lot lighter...
[06:11] <nigelvh> True enough
[06:11] <heathkid> just remember... *this side up*
[06:11] <heathkid> :)
[06:12] <arko> evening
[06:12] <heathkid> hello arko
[06:12] <arko> sup heathkid
[06:12] <nigelvh> Evening arko
[06:12] <Spoz> what are peoples thoughts on using hydrogen here
[06:13] <arko> it goes boom
[06:13] <Spoz> we are heading in that direction
[06:13] <nigelvh> Be careful
[06:13] <heathkid> ah, just trying to decide if a chip antenna on a HAB would work as well as a much heavier helix antenna...
[06:13] <Spoz> yeah, Im planning on building an anti-static rig
[06:13] <nigelvh> I'm headed that direction as well I thnk
[06:13] <heathkid> I like hydrogen
[06:13] <Spoz> its 1/4 the price
[06:13] <Spoz> mainly
[06:13] <nigelvh> Much cheaper and is in good supply
[06:13] <Spoz> and as far as I can tell, theres no problem using acetylene regs on it
[06:13] <heathkid> but... I've also *never* done a launch YET
[06:14] <Spoz> which are easy to source
[06:14] <Spoz> hmm
[06:14] <Spoz> ours is in two weeks
[06:14] <nigelvh> If you haven't sourced your gas yet, I'd get on that.
[06:14] <heathkid> I'm waiting until probably March
[06:14] <Spoz> there are short lead times here
[06:14] <Spoz> a few days at most
[06:15] <Spoz> but yeah its a decision I'll be making by next weekend
[06:15] <heathkid> UK?
[06:15] <Spoz> I think we'll go with H2
[06:15] <Spoz> no AUS
[06:15] <heathkid> ah
[06:15] <heathkid> I used to work for a company based in Perth
[06:16] <Spoz> I've been there.. but its about 4500km away from my home :)
[06:16] <heathkid> sucked that by the time I got home... what do you know... Open for Business!
[06:16] <Spoz> hehe
[06:17] <heathkid> I was working 24/7 for a couple years when I wasn't asleep at the keyboard or on the phone (yes, I fell asleep during a few conference calls)
[06:18] <Spoz> :p
[06:18] <heathkid> heh... try working over 150 hours a week
[06:19] <Spoz> Im a little bit nervous about the flight, I've been the only one working on it so Im really hoping everything works as planned
[06:19] <Spoz> :( what did you do?
[06:19] <heathkid> what are you using for tracking?
[06:19] <Spoz> 1W 900MHz RFD900 radio modems
[06:19] <nigelvh> Are those digital or analog?
[06:20] <Spoz> I havent tested them at those ranges but the designer has
[06:20] <nigelvh> Looks like digital
[06:21] <Spoz> they are digital
[06:21] <heathkid> ewww
[06:21] <nigelvh> Certainly let us know how they work. I've had students in classes try digital radios before and had them fail to sync right and get zero data.
[06:21] <heathkid> I want analog and digital
[06:21] <Spoz> yeah
[06:21] <Spoz> it is making me nervous too
[06:21] <Spoz> we also have an analog video transmitter on board
[06:21] <Spoz> and a backup GSM locator
[06:22] <nigelvh> Does the video have an overlay with GPS position?
[06:22] <heathkid> first launch Spoz?

[06:22] <heathkid> I've spent almost a year working on planning my first launch
[06:23] Nick change: Mike -> Guest30453
[06:23] <Spoz> yes first launch. And there is no overlay on the video
[06:23] <Spoz> that would have been a good idea actually, OSDs are not that expensive
[06:23] <Darkside> what analog transmitter are you using?
[06:23] <Spoz> lawmate 1000mw 1200mhz
[06:23] <Darkside> what band and what power?
[06:23] <Darkside> ahh
[06:23] <Spoz> again, not tested at those ranges
[06:23] <Darkside> and you have lots and lots of gain on the ground?
[06:23] <heathkid> and working on a new tracker (telemetry... I think the tracker is the ground based unit)
[06:23] <Darkside> we've done the link budgets for those already
[06:24] <Spoz> yeah, about 12db helicals
[06:24] <Spoz> the gain is hard to measure though, calculated was about 15
[06:24] <Darkside> with about 30dBi gain on the ground you'll get about 40km path
[06:24] <Darkside> well, where you get full colour anyway
[06:24] <nigelvh> Are the balloon antennas also helical?
[06:24] <Darkside> outside that you'll get black and white imagery ish
[06:24] <Spoz> no, the video antenna is a skew planar
[06:24] <Darkside> this link budget was with a small circ polarised antenna on the payload
[06:24] <Spoz> yeah
[06:24] <nigelvh> Yeah
[06:24] <Darkside> so similar gain to yours
[06:24] <Darkside> but yeah, you want a shitload of gain on the ground
[06:25] <Darkside> its why we're goin gwith 70cm ATV
[06:25] <Darkside> not 23cm
[06:25] <nigelvh> We've used 1W 70CM ATV before
[06:25] <Spoz> hmm, well its too late to redo my antennas
[06:25] <SpeedEvil> Spoz: you're also in a us?
[06:25] <Darkside> you'll get good launch video i'm sure
[06:25] <SpeedEvil> aus
[06:25] <Spoz> when I worked it out 12 looked enough
[06:25] <Darkside> but i doubt it'll work well when it's right up in the air
[06:25] <Spoz> yeah we hope to recover the cards with HD video
[06:25] <nigelvh> A circular antenna on the balloon, and a handheld yagi works well
[06:25] <Spoz> speedevil, yes in brisbane
[06:25] <Darkside> orly
[06:25] <SpeedEvil> :-)
[06:25] <Darkside> Spoz: hold on, 1200MHz video
[06:25] <heathkid> Spoz: don't count on recovering your first launch payload
[06:26] <Darkside> you have a licence for that, right?
[06:26] <Darkside> >_>
[06:26] <Spoz> its supervised by someone with a license
[06:26] <Darkside> but theres no overlay on the video
[06:26] <Spoz> no, I know
[06:26] <Darkside> which means it isn't ID'd
[06:26] <nigelvh> We have an overlay on the video to ID and give GPS coordinates in case of other tracker failures.
[06:26] <Darkside> anyway, avoid repeater inputs and nobody will care
[06:27] <Spoz> yeah I should have got an OSD
[06:27] <heathkid> the board we're working on now does APRS, RTTY, and CW
[06:27] <SpeedEvil> do you have a big antenna on the bottom?
[06:27] <SpeedEvil> for video
[06:27] <Spoz> darkside, yeah we will be out in the middle of nowhere
[06:27] <Darkside> Spoz: yeah, you wont have a problem

[06:27] <Spoz> hehe
[06:27] <Darkside> hardly anyone uses 23cm here anyway
[06:27] <nigelvh> We use a circularly polarized moxon.
[06:27] <Darkside> it's great in adelaide - the club i'm involved in controls the 23cm repeater >_>
[06:27] <Darkside> so we just... turn it off
[06:27] <Spoz> hehe
[06:28] <Spoz> I should probably look up where those are
[06:28] <Darkside> yeah, theres a repeater list on the WIA site
[06:28] <Darkside> so what else are ytou flying?
[06:28] <heathkid> you guys are upside down
[06:28] <Darkside> oh wait, the 900mhz things
[06:28] <Spoz> are you part of project horus at all?
[06:28] <Darkside> Spoz: i am :-)
[06:28] <Spoz> ahh, I exchanged a couple of emails with terry a while back
[06:28] <Darkside> i designed all the new project horus payloads
[06:28] <Darkside> terry is very very busy
[06:28] <Spoz> yeah
[06:29] <Darkside> you're lucky you got a response at all
[06:29] <Spoz> I stopped writing him emails for that reason :P
[06:29] <Darkside> :P
[06:29] <heathkid> what is everyone looking for in telemetry as well as ground based tracking?
[06:29] <Darkside> anyway, i don't like ths 900mhz modems
[06:29] <Spoz> just because theyre digital?
[06:29] <Darkside> not just that
[06:30] <Spoz> what else?
[06:30] <Darkside> a lot of them don't quite adhere to our 900mhz band
[06:30] <Spoz> are you talking specifically about the RFD900
[06:30] <Darkside> not specifically
[06:30] <nigelvh> We've used 900MHz stuff on our flights and it has worked well, but it was analog.
[06:30] <Darkside> the XTEND modems were ones we've played with before
[06:30] <Spoz> ok
[06:30] <Darkside> turned out they were broadcasting out of our 900mhz band
[06:30] <Darkside> which is 918-something
[06:30] <Darkside> i forget
[06:30] <Darkside> but it was TXing down at 910
[06:30] <Spoz> I know the guy who designed the rfd900 and he's pretty meticulous
[06:31] <Darkside> anyway
[06:31] <Darkside> my advice is turn the baud rate down as low as you possibly can
[06:31] <nigelvh> Seconded
[06:31] <Spoz> he said below about 27k theres no added increase in range
[06:31] <Darkside> heh
[06:32] <Darkside> anyway, we like our RTTY stuff
[06:32] <Spoz> 24*
[06:32] <Spoz> yeah
[06:32] <Darkside> doesn't suck 800mA :-)
[06:32] <Spoz> I would have gone with that if I didnt have everyone up here telling me how good the radio modems are
[06:32] <Darkside> pff
[06:32] <Spoz> we'll see if it was wise
[06:32] <nigelvh> Yeah, 1W is generally more than you'd need, but you're working digital, so better to play safe.
[06:32] <Darkside> i know a few certain people that love these kinds of modems
[06:32] <Spoz> they use them for FPV
[06:33] <nigelvh> I do APRS with 250mW
[06:33] <Darkside> but we like the ultra high reliability wwe get with the RTTY payloads
[06:33] <Darkside> being able to decode it at 800km is cool too
[06:33] <Darkside> aaaaand no special hardware required on the ground
[06:33] <Darkside> well, apart from a 'regular' sideband receiver
[06:33] <Darkside> lets more people receive data - and adds redundancy
[06:33] <Spoz> I liked the ability to send packets back to the balloon, part of the reason I went with these
[06:34] <Darkside> we can do that too :P
[06:34] <Spoz> orly
[06:34] <nigelvh> Yeah, if we had the receiving network you guys do, we'd still use RTTY, but APRS gives us the multiple receivers.
[06:34] <Darkside> (with a different system)
[06:34] <Spoz> hm
[06:34] <Darkside> i've had an uplink system going for a while
[06:34] <Darkside> using the RFM22Bs
[06:34] <Darkside> i keep that separate to the main telemetry though
[06:34] <Spoz> right
[06:34] <Darkside> main telemetry is just that. a constant downlink
[06:34] <Spoz> yeah
[06:35] <Spoz> Im only sending a short packet every second
[06:35] <Darkside> the uplink payload is on a different freq, well away from the main telemetry, and is used to control other stuff
[06:35] <Darkside> ahh - theres another reason why i like our telemetry system - it transmits constantly
[06:35] <Darkside> if the GPS fails, or even if the micro fails - it'll still transmit
[06:35] <Spoz> hmm
[06:35] <Darkside> and we can use direction-finding techniques to recover the payload
[06:36] <Darkside> thats a lot harder to do with a short wideband packet
[06:36] <Spoz> Im not equipped or experienced to do that kind of stuff
[06:36] <Darkside> yeah
[06:36] <Darkside> not everyone is
[06:36] <Darkside> but it's a nice backup
[06:36] <Spoz> amateur radio would have been another thing on my endless todo list
[06:36] <nigelvh> That's part of why I'm looking forward to trying my new transmitter.
[06:37] <nigelvh> Use APRS every so often for position packets, and then I can just do RTTY or CW on another frequency dedicated to us for direction finding.
[06:37] <Darkside> but yeah, i generally distrust the higher baud rate stuff
[06:37] <Darkside> i mean, if we had a need for higher baud rates i'd use it
[06:37] <Darkside> but we want ultra high reliabiltiy over anything else
[06:37] <Spoz> yeah
[06:37] <Darkside> we get a position about every 3-4 seconds
[06:38] <nigelvh> I flew it last year and it worked well for us. It's just really our only way to get the multiple receivers like you have.
[06:38] <Darkside> which is perfect for tracking and recovery
[06:38] <Spoz> that is heaps, I have too many updates
[06:38] <Spoz> I get once a second and then I filter out 4 out of 5 for the webpage
[06:38] <nigelvh> When we do a flight, it's just us out there listening unless we use APRS.
[06:38] <Darkside> so you're rolling your own tracking site?
[06:39] <Darkside> thats the other useful thing about RTTY - we can use spacenear.us
[06:39] <Spoz> yeah it's down at the moment due to a coding stuffup this morning, waiting to get a backup
[06:39] <Darkside> and spacenear.us is well supported
[06:39] <Darkside> we also have our own offline tracking systems in our chase cars
[06:39] <Spoz> but the barebones are at http://balloon.theredpaintings.com
[06:39] <Spoz> yeah, all we have to go off is the monitor window showing what is being uploaded to the server
[06:39] <Spoz> so chasing will consist of typing gps coords in whenever we want an update
[06:39] <Darkside> mm
[06:39] <Spoz> its very rushed
[06:40] <Darkside> when are you launching?
[06:40] <Spoz> thats assuming we cant use the site
[06:40] <Spoz> two weekends from now
[06:40] <Darkside> k
[06:40] <Darkside> you coudl write something to parse the data and generate position strings to upload to habitat
[06:41] <Darkside> that way you get the spacenear.us tracking site, and live predictions
[06:41] <nigelvh> The live predictions are nice.
[06:41] <Darkside> yep
[06:41] <Darkside> thats really the most useful thing
[06:41] <Spoz> what is habitat?
[06:41] <Darkside> the backend to spacenear.us
[06:41] <Spoz> oh
[06:42] <Darkside> it wouldn't be too hard to generate something that can be uploade
[06:42] <Darkside> dthe guys that can help you with that will be online later tonight
[06:42] <Spoz> no, I already have a python script that Im using to upload to SQL
[06:42] <Spoz> Im sure I could modify it
[06:42] <Darkside> yep
[06:42] <Darkside> if its in python it shouldn't be hard to get something going
[06:43] <Darkside> thats what all of habitat was written in i think
[06:43] <Spoz> hm, so how does this work
[06:43] <Spoz> anyone can use spacenear.us
[06:43] <Darkside> yup
[06:43] <Darkside> it's designed to work with dl-fldigi, the demodulator we use for RTTY
[06:44] <Darkside> but it can be made to work with other systems
[06:44] <Darkside> i don't know much of the specifics, you'll need to talk to either Randomskk or DanielRichman
[06:44] <nigelvh> I've had you guys grab APRS strings and place them on spacenear.us
[06:44] Nick change: soafee-chan -> spacekitteh
[06:44] <Spoz> live predictions would be awesome
[06:44] <Darkside> best to join #habhub
[06:44] <Darkside> as thats where the development talk happens
[06:45] gonzo_mob (~gonzo_mob@213.205.236.1) joined #highaltitude.
[06:46] <Spoz> cool thanks
[06:47] <Darkside> still, teh whole 800ma thing
[06:47] <Darkside> heh
[06:47] <Darkside> thats nuts
[06:47] <nigelvh> Nuts for you guys
[06:47] <Darkside> heh
[06:47] <nigelvh> We've easily done twice that a time or two
[06:48] <Darkside> well our main telemetry payload draws something like 100mA
[06:48] <Darkside> oh yeah, we've had similar things before too
[06:48] <Darkside> but that was stuff like voice repeaters
[06:48] <Spoz> my total draw is much more because we have a 1W video tx as well
[06:48] <Darkside> yeah
[06:48] <Darkside> linear amp
[06:48] <Darkside> got heatsinking?
[06:48] <Spoz> and if this doesnt work then clearly we need more power :p
[06:48] <Darkside> it's going to get bloody hot
[06:48] <nigelvh> Yes, heatsinking will be very important
[06:48] <Spoz> yeah heatsink is on the to-do list as well
[06:48] <Spoz> but the microcontroller shuts it down if it gets too hot
[06:49] <Darkside> the problem will be getting the heat away
[06:49] <Darkside> as there's no air to transfer it to
[06:49] <Spoz> yeah I figured as much
[06:49] <nigelvh> In general it has to be really good heatsinking as there's little air to carry it away
[06:49] <Spoz> suggestions?
[06:49] <Darkside> copper foil
[06:49] <Spoz> I was going to try making a thermal path to the batteries
[06:49] <Spoz> not sure if thats wise, the batteries might stay warm enough
[06:50] <Darkside> what battereis are you using
[06:50] <Spoz> lipos
[06:50] <Darkside> mmm
[06:50] <Darkside> well with that much current draw they might be ok
[06:50] <nigelvh> We've used those before, our payloads stay warm (no colder than -10) so we've never had any issues
[06:50] <Darkside> we generally don't use them, as we draw so little current the lipo's freeze
[06:50] <Darkside> mm
[06:50] <Darkside> depends how warm your payloads stay
[06:51] <Darkside> our standard is AA Energizer lithiums
[06:51] <nigelvh> I recently picked up some of the lithium AAs to test with, they're surprisingly light compared to a standard AA
[06:51] <Darkside> yep
[06:51] <Darkside> they're excellent
[06:51] <Darkside> 12g for a AA
[06:51] <Spoz> should I look at those instead?
[06:51] <nigelvh> I was weighing at 14g/AA
[06:51] <Darkside> Spoz: not for the camera
[06:51] <Darkside> maybe for the telemetry
[06:52] <Darkside> nigelvh: yeah might have been that
[06:52] <Darkside> i'd stick with the lipos for the camera - that isn't a primary system
[06:52] <nigelvh> VS 24grams for a standard duracell alkaline
[06:52] <Darkside> but it ight be worth using the AAs for the telemetry - that *has* to run
[06:52] <Darkside> you get 3Ah out of a 1.5V AA lithum battery
[06:52] <Darkside> that runs one of Upu's pico payloads for 37 hours
[06:53] <nigelvh> Yes, but Upu is running his payload at 1.6V
[06:53] <Spoz> hmm
[06:53] <Spoz> Should I still be insulating the box with all this heat?
[06:54] <Darkside> yes
[06:54] <nigelvh> Yes
[06:54] <nigelvh> Just expose some way for heat to escape the hot things.
[06:54] <Darkside> mm
[06:54] <Darkside> we do that by running thin copper foil to the outside of the payload
[06:54] <nigelvh> Exactly
[06:54] <Spoz> right
[06:54] <Darkside> and providing a large area for it to dissipate over
[06:54] <Spoz> where do you get that foil from in aus?
[06:54] <Darkside> the copper foil is probably the lightest way to do it
[06:54] <Darkside> dunno
[06:54] <Darkside> lol
[06:55] <Spoz> oh
[06:55] <Darkside> we just had some
[06:55] <nigelvh> hardware store might have some
[06:55] <Spoz> I only have some really thin stuff
[06:55] <Spoz> like an inch wide
[06:55] <Spoz> sticky on one side
[06:55] <Spoz> or I could use alfoil I guess, that was my first plan
[06:55] <Darkside> thats probably too thin
[06:55] <Darkside> alfoil is probably too thin too
[06:55] <Darkside> though its worth a shot
[06:56] <Darkside> make it, turn it on, see how hot the things gets
[06:56] <Spoz> yeah
[06:56] <Spoz> Im using the VTX as a kind of thermostat though
[06:56] <Spoz> since the live video is not as important as recovering the cards with HD
[06:56] <Darkside> yeah..
[06:57] <Darkside> have you done any link tests with the 900mhz stuff?
[06:57] <Spoz> plus it sounds like we wont get video the entire flight
[06:57] <Darkside> like, mountaintop to mountaintop?
[06:57] <nigelvh> You should easily get video
[06:57] <Darkside> nigelvh: depends on the ground antenna
[06:57] <Spoz> well, the designer did a test where he got 30km range with omnis
[06:57] <Darkside> 1W TX, 23cm - 12dBi on ground
[06:57] <Spoz> and I tried to do a test
[06:58] <Spoz> we stuck one on a mountaintop and one on my friends light aircraft
[06:58] <Spoz> and he went for a fly
[06:58] <Spoz> we got a brief link as he taxi'd and then it dropped out as soon as he took to the air
[06:58] <nigelvh> Granted we use 70cm, but 1W transmitter into a circular antenna on the balloon and a handheld 5 ele yagi works great for us.
[06:58] <Spoz> and didnt regain
[06:58] <Spoz> initial link was from 5km
[06:58] <Darkside> nigelvh: yeah, its a lot easier on 70cm
[06:58] <Spoz> but we found out later the mountaintop we were on had some 900MHz stuff up there
[06:58] <Spoz> 1W dishes
[06:58] <Darkside> but the receiver has a filter on it
[06:59] <Darkside> oh
[06:59] <Darkside> ism band stuff
[06:59] <Spoz> yeah
[06:59] <Darkside> well that isn't goign to help :P
[06:59] <Spoz> no
[06:59] <Spoz> so I put it down to that
[06:59] <Darkside> you hope :P
[06:59] <Spoz> I really do :p
[06:59] <nigelvh> Yeah...
[06:59] <Darkside> so you have a yagi for the ground end?
[06:59] <Spoz> no, a helix
[07:00] <Darkside> for 900mhz?
[07:00] <Spoz> yeah
[07:00] <Darkside> ok
[07:00] <Darkside> should be ok
[07:00] <Darkside> i hope
[07:00] <Spoz> http://balloon.theredpaintings.org/antennae.jpg
[07:00] <Spoz> derp change that to .com
[07:01] <Darkside> jeez that huge
[07:01] <Darkside> :P
[07:01] <Spoz> yeah
[07:01] <Darkside> we generally use 1/4 wave monopoles to receive our telemetry
[07:01] <Spoz> Im always staggered by how resilient analog is
[07:01] <Darkside> yep
[07:01] <Spoz> cant believe you use omnis on both ends and can get away with a 10mW tx
[07:02] <Spoz> Im somewhat regretting going with digi
[07:02] <Darkside> well, we use 25mW in australia
[07:02] <Darkside> but yeah
[07:02] <Spoz> but we'll see
[07:02] <Darkside> if anything, it's worth switching for the lower power consumption...
[07:02] <Darkside> becase 800mA at 5W is ridiculous
[07:02] <Darkside> 5V*
[07:03] <Spoz> yeah
[07:03] <nigelvh> Yeah
[07:06] <Darkside> what gps unit are oyu using?

[07:47] <Upu> ultimate gps tops out at 27km
[07:47] <Upu> morning
[07:48] <Spoz> Ive been told the new 3339 chips dont have a limit?
[07:48] <Spoz> it was the 3329 that was limited to 27k
[07:49] <Spoz> their site says its been tested to 27km and worked
[07:51] <Spoz> someone experienced an issue with the in-chip logging, where the altitude is only stored as an integer
[07:52] <Spoz> so above 32000m the values rolled over to negative
[07:52] <Spoz> but that shouldnt be an issue with the output, I hope
[07:52] <Spoz> and we can correct that if it happens, just probably not on the fly
[07:53] <Upu> spoz I'll give you some code
[07:53] <Upu> you can run to check the firmware
[07:53] <Spoz> oh cool
[07:54] <Upu> but will be about 45 mins , I need to walk the dog
[07:54] <Upu> back soon
[07:54] <Spoz> no problem, I'll still be around. cheers

[08:25] <Spoz> well damn it
[08:33] <Upu> 27km
[08:33] <Spoz> adafruit screws me again
[08:33] <Spoz> I have to stop buying from them
[08:33] <Upu> may I take this opportunity to introduce you to my shop of many things ? :)
[08:33] <Spoz> haha
[08:33] <Spoz> sure thing
[08:33] <Spoz> can you deliver to aus in a week?
[08:33] <Upu> what are you connecting it to ? 3.3v or 5v microcontroller ?
[08:34] <Spoz> 5v micro
[08:34] <Upu> http://ava.upuaut.net/store/index.php?route=product/product&path=59_60&product_id=68
[08:34] <Spoz> Im using the 3v reg on the ultimate gps board to power my sensors though
[08:34] <Upu> 50km limit
[08:34] <Spoz> so I need a 3v3 reg to go with it
[08:34] <Upu> that as a 3.3v output on it
[08:34] <Upu> as long as your sensors don't take more than say 40mA
[08:35] <Upu> Not sure Oz in a week is possible, unless you're willing to pay for UPS in which case yes
[08:35] <Upu> Airsure is reasonably quick but may be just over a week
[08:35] malgar (~malgar@151.46.134.24) joined #highaltitude.
[08:36] <Upu> in fairness to Adafruit I think the manufacturer screwed them over, they've since got or were getting some that they believe have a limit of 40km
[08:37] <Upu> which is still probably too low given a 1000g balloon has achieved that
[08:37] <Spoz> hmm
[08:37] <Upu> I know the 5223 modules can do at least 38.5km as I flew one for them
[08:38] <Spoz> and I suppose theres no way to upgrade the firmware

[08:40] <Spoz> is normal delivery time within 2 weeks to aus?
[08:40] <Spoz> our launch is exactly two weeks from now
[08:40] <Spoz> I wanted some time to test it first
[08:40] <Upu> if you get Airsure
[08:41] <Upu> I'm fairly confident it will be there in 2 weeks
[08:41] <Upu> normal parcel rates can be anything
[08:41] <Upu> weeks
[08:41] <Upu> However all I can guarantee is I'll post it tomorrow :)
[08:42] <Spoz> is airsure the international signed
[08:42] <Spoz> or just regular airmail
[08:42] <Upu> its above international signed
[08:43] <Spoz> ok
[08:43] <Upu> Airsure is its own thing, tracked and insured
[08:43] <Spoz> let me look at the budget, this would be my third gps as it is
[08:43] <Spoz> I will get in tonight if I can
[08:43] <Upu> what was the first ?
[08:43] <Spoz> the old mediatek one >.<
[08:43] <Upu> heh
[08:43] <Spoz> yeah
[08:44] <Spoz> then I saw this one that said "fixed for high altitude!"
[08:44] <Spoz> "tested to 27km!"
[08:44] <Upu> it is fixed
[08:44] <Upu> entirely correct
[08:44] <Spoz> what they dont say is they tested it beyond 27km and it stopped working
[08:44] <Upu> exactly :)
[08:44] <Upu> it is on the forums though
[08:44] <Spoz> I checked the forums when I ordered (right when it came out)
[08:44] <Spoz> there was some discussion and everything indicated it would work
[08:45] <Upu> Maximum Altitude for MTK3339: no limit that's crap
[08:46] <Spoz> yeah
[08:46] <Spoz> I think I'll be emailing them for a refund
[08:47] <Upu> tell them the firmware version
[08:49] <Spoz> where does it say that?
[08:49] <Spoz> maximum altitude: no limit, I mean
[08:50] <Upu> some Adafruit reseller site
[08:54] <Upu> MAX7 will blow it out of the water anyway and the only thing the ublox chips really miss is the 10hz update
[08:58] <Spoz> as long as I can set it to GPGGA sentence output at 1Hz I'm happy
[08:58] <Upu> yeah hab doesn't need 10hz
[08:58] <Spoz> of course
[08:58] <Spoz> I'm only updating once every 5 seconds to the website

[09:03] <Spoz> not 604
[09:03] <Upu> hmm ok
[09:04] <Upu> mail their support double check it
[09:04] <Spoz> $PMTK605*31
[09:04] <Upu> the one I have is 604
[09:04] <Spoz> ok, I got this from the datasheet on their page
[09:04] <Spoz> Ive mailed their support asking for a refund
[09:05] <Upu> ok be interested to see what they say
[09:05] <Upu> unless they've done something really dumb like removed the 27km limit and left the firmware version as it was
[09:05] <Spoz> yeah I had one gripe with them in the past and they were very disinterested
[09:05] <Upu> that would be stupid
[09:05] <Upu> you wouldn't be able to tell which modules were which
[09:05] <Spoz> yeah I suppose so

[11:07] <Hix> cool - getting there with this shield. NTX2 at the bottom and MAX6 at the top, right next to ant
[11:08] <eroomde> you'll want to have pull-up resistors on the lines between the gate and the transmission line
[11:08] <eroomde> eg a pullup to 3v3 on the gps side and a pullup to 5V on the arduino side

[12:39] <Upu_M0UPU> ok thanks
[12:39] <navrac-office> same here
[12:41] <navrac-office> mind you - I've got 4 RX going so the average is 434.1965
[12:41] <chrisg7ogx> auto configure gives shift of 425
[12:41] <navrac-office> I must get round to calibrating this lot properly
[12:41] <navrac-office> shift is closer to 450
[12:41] <GMT> 'OGX, you can adjust the shift in FLDIGI
[12:43] <chrisg7ogx> yes got that last time thanks
[12:43] <navrac-office> the signal isnt as strong as i'd expect - but that could be a problem with my aerial

[13:26] <cuddykid> domlin: ft817
[13:27] <G0MJW-PC> Funcube dongle Pro+
[13:27] <chrisg7ogx> agree
[13:27] <navrac-office> to be honest just about anythings works
[13:27] <chrisg7ogx> if strapped fer cash then tv dongle
[13:28] <domlin> i've only had experience with chrisstubbs93's EZCap
[13:28] <domlin> is the funcube much different?
[13:28] <chrisg7ogx> just received one of them nice n sturdy
[13:28] <navrac-office> I've got a sdr dongle a funcube an ft726, an ft790 and a yupiteru 7100 - the perfromance (with the hab amp) is roughly the same
[13:28] <G0MJW-PC> Even my EZCAP TV stick works - needed a protection diode though and that is SMT so it depends on experience. Not easy yo set up. You can also try FT790, very cheap.
[13:29] <navrac-office> on really weak signals the funcube+hab amp just beats the others.
[13:29] <G0MJW-PC> Starting to decode charecters from Atlas.
[13:29] <navrac-office> and the ezcap comes last
[13:29] <chrisg7ogx> freq?
[13:29] <cuddykid> wonder who will be the first to upload a packet
[13:29] <chrisstubbs93> Maybe i should invest in an amp then, i have UPU's ezcap witht he diode fitted

[14:32] <jcoxon> make sure you're SQL is off
[14:32] <jcoxon> on dl-fldigi that is

[14:46] <junderwood_M0JCU> is it safe to hit f5 on spacenear.us yet?
[14:46] <Upu_M0UPU> no don't
[14:46] <Upu_M0UPU> it won't load
[14:46] <number10_M0MDB> not far off Thorpe Ness acording to my local tracker
[14:46] <GMT> should we stop sending decodes to Spacenear?
[14:46] <Upu_M0UPU> jcoxon did you set the live predictor to a very low decent rate ?
[14:47] <Upu_M0UPU> No GMT you're uploading to Habitat which is fine
[14:47] <Upu_M0UPU> its just the spacenear.us server thats broken
[14:47] <jcoxon> Upu_M0UPU, not me
[14:47] <jcoxon> but its probably not a good idea
[14:48] <Upu_M0UPU> no when I've seen it die like this thats what happened
[14:49] <fsphil> I though that scrolling bug was only affecting linux
[14:49] <number10_M0MDB> nanu over the beach
[14:49] <fsphil> it is happening on windows and mac?
[14:49] <Upu_M0UPU> Nanu over the sea :/
[14:51] <Upu_M0UPU> bug is on windows too
[14:51] <fsphil> it seems to be in fldigi too
[14:51] <fsphil> I suspect it's a bug from upstream
[14:51] <Upu_M0UPU> ah my putty session to spacenear.us died
[14:52] <fsphil> poo
[14:52] <Upu_M0UPU> load average was 80 before it died

[17:39] <OZ1SKY_Brian> freezer and then into the oven, to test drift :-)
[17:39] <Geoff-G8DHE> At least the centre frequency has stopped drifting now.
[17:40] <SP9UOB_Tom> fsphil: re-init of rfm22 seems to solve the problem
[17:40] <Geoff-G8DHE> Ah missed that!
[17:40] <fsphil> that's very odd
[17:40] <SP9UOB_Tom> fsphil: looks like internal calibration or so
[17:40] <fsphil> so after re-init the signal is solid and decoding?
[17:41] <Geoff-G8DHE> It been solid here for the last couple of hours, other thewn the frequency drift.
[17:41] <SP9UOB_Tom> fsphil: right, im re-initting module every 90 seconds - work like a charm
[17:42] <fsphil> does the frequency shift when you re-init?
[17:42] <number10_M0MDB> I did a re-init every 10 frames for NANU - worked like a charm until it went into the sea
[17:42] <SP9UOB_Tom> fsphil: no
[17:43] <SP9UOB_Tom> number10_M0MDB: seawater is not specially good for rfm22 ;-)
[17:43] <number10_M0MDB> especially when powered SP9UOB_Tom
[17:44] <SP9UOB_Tom> number10_M0MDB: but dome hydrogen is formed ;-)
[17:44] <SP9UOB_Tom> some
[17:44] <number10_M0MDB> nor enough SP9UOB_Tom looking at the current altitude
[17:44] <number10_M0MDB> not
[17:44] <SP9UOB_Tom> number10_M0MDB: nex time use bigger batteries ;-)
[17:45] <SP9UOB_Tom> or plutonium thermoelectric generator :-)
[17:45] <number10_M0MDB> lol
[17:45] <SP9UOB_Tom> number10_M0MDB: then it can be found easilly
[17:46] <number10_M0MDB> may require something larger than a 36" foil ballon

[18:09] <GMT> can't find any online receivers in France that will help - a couple down near Toulouse, that's all.
[18:09] <jcoxon> just tried to send packets
[18:09] <jcoxon> nothing
[18:10] <G0MJW-PC> It is very strong but wide filters are not helping with ISI
[18:11] <jcoxon> G0MJW-PC, must admit i haven't seen the carrier curve like that before

[18:18] <G0MJW-PC> Not at this ascent rate, you will be needing Swiss and Italians
[18:19] <jcoxon> it should stop curving west and head south

[20:06] <Upu_M0UPU> I was just saying to daveake earlier so many recieversnow
[20:06] <Lunar_Lander> yea and some are even in inaccessible locations such as a physics lab on a weekend

[22:00] <GMT> 'OGX, it will slowly descend as the helium cools and contracts, and the balloon loses its lift
[22:01] <chrisg7ogx> ok sri but what decides when that happens?
[22:01] <jcoxon> GMT, it won't descend that much
[22:01] <jcoxon> more that it'll rise in the morning
[22:01] <GMT> the balloon is not full of gas, there's room for expansion; but not enough expansion to burst the balloon;
[22:02] <chrisg7ogx> yes exactly i could understand a cooling and descent during the darkness
[22:02] <GMT> as it cools and contracts it descends; in the morning with sunlight, gas expands and has more lift
[22:02] <F6AGV> why altitude is constant ?
[22:02] <Upu_M0UPU> its floating F6AGV
[22:02] <g6uim> looks like time to point the beam SE

[22:06] <domlin> i heard that chrisstubbs93 dropped his payload and it now doesn't work?
[22:07] <g6uim> the better signal seems to have improved the lock speed
[22:07] <chrisg7ogx> the link you posted at 2154 shows gradual descent
[22:07] <GMT> F6AGV: what about F8TIW in Orleans, heard anything from him?
[22:07] <jcoxon> chrisg7ogx, oh thats something different
[22:07] <F6AGV> no
[22:07] <jcoxon> hysplit is a special program
[22:07] <chrisg7ogx> its not descent?
[22:07] <jcoxon> which predicts the path of a single particle of gas in the atmosphere
[22:08] <F6AGV> i hope he can receive all Night ?
[22:08] <chrisg7ogx> oh gawd
[22:08] <jcoxon> its just convient to use as the balloon follows a similar path
[22:08] <jcoxon> we usually ignore that altitude plot
[22:08] <jcoxon> just use the map as a guide
[22:08] <jcoxon> its an amazing program

[22:23] <Upu_M0UPU> thanks OZ1SKY_Brian for reminding me
[22:23] <OZ1SKY_Brian> Upu_M0UPU yeah that allways a good idea :-)
[22:24] <OZ1SKY_Brian> np
[22:24] <Upu_M0UPU> though that said it still decoding on the FCD/Colinear just fine
[22:24] <OZ1SKY_Brian> you must be down at 1deg elevation
[22:25] <OZ1SKY_Brian> or ½deg
[22:26] <Upu_M0UPU> I leave it at 0
[22:26] <Upu_M0UPU> tbh I hardly touch EL
[22:26] <Upu_M0UPU> If I was doing this again I wouldn't bother with EL
[22:26] <OZ1SKY_Brian> the antenna is much wider then that, so no problem at 0
[22:27] <Randomskk> yea el rapidly becomes pointless
[22:27] <Randomskk> nice for brief bit if you're launching from the tracking site (or near enough)
[22:27] <OZ1SKY_Brian> mine is 10-15deg wide in elevation
[22:27] <Upu_M0UPU> same here
[22:28] <Upu_M0UPU> and if a payload is that close I can use the colinear
[22:28] <OZ1SKY_Brian> yes easy
[22:28] <Randomskk> tbh if that close probably still pick it up anyway on the yagi
[22:28] <Randomskk> but yea
[22:29] <jcoxon> hmmm i've got terrible interference here
[22:29] <jcoxon> someone must have something on
[22:29] <OZ1SKY_Brian> or a payload with a broken antenna, then it will be very usefull
[22:29] <Upu_M0UPU> yep
[22:30] <OZ1SKY_Brian> while i was doing satellite, 30-40deg was no problem with out elevation

[22:37] <mrShrimp> I was just taking a vacation in France, coincidentally. Hopefully it isn't stuck in some tree hours into the countryside.
[22:37] <mrShrimp> when it lands

[22:41] <eroomde> Adam012: so
[22:41] <eroomde> 'it's not working' is no use to anyone
[22:41] <eroomde> so
[22:42] <chrisg7ogx> yeah you'll have to stay up put the coffee on1
[22:42] <eroomde> firstly, have you got either of the gps or the radio working individually in any capacity and if so, in what capacity?
[22:42] <daveake> Adam012 There's a story about someone being lost and asking directions, and being told "You can't get there from here". Well, if you want a working tracker, that's where you are.
[22:43] <daveake> Getting the altitude into a string is, I'm sorry to tell you, the least of your problems in that program
[22:44] <Adam012> In the first iteration of the code we called an NMEA string from the GPS, sent it to the NTX2 which transmitted it.
[22:44] <eroomde> did that work?
[22:45] <g6uim> I will stick with it will leave the system running overnight. may have to go back to the colinear at some point until I can get in the roof again
[22:45] <Upu_M0UPU> thanks g6uim you will be awarded many HAB points
[22:45] <jcoxon> its fun this isn't it

[22:46] <g6uim> there is an errant o in the last word there
[22:46] <Geoff-G8DHE> Right found I can get both records now, if I leave AFC off and just set the bandwidth high, so lonng as the Tx doesn't drift in frequency .....
[22:46] <eroomde> ok, so the error has crept in somewhere between that bit of code and the latest bit of code?
[22:46] <g6uim> surely it should be HAB pints
[22:46] <jcoxon> http://ready.arl.noaa.gov/hysplitout/17159_trj001.gif
[22:47] <Upu_M0UPU> if you come to the conference next year I'm sure that can be arranged
[22:47] <eroomde> don't drive in if you're coming to collect hab points
[22:48] <Adam012> With the latest bit we were doing a test to see if we could poll using a UBX command to get the time and then transmit that info by radio. This was proof of concept. We than plan to poll for other pieces of info.
[22:48] <eroomde> ok
[22:48] <eroomde> well
[22:48] <eroomde> when trying something new, i'd get rid of everything unecessary

[22:50] <Adam012> Are polling for time correctly?
[22:51] <Adam012> We were using the radio because we had heard that the Arduino buffer was easily overfilled
[22:51] <Adam012> using software serial
[22:51] <chrisg7ogx> I'm going to Brighton tomorrow and will look for a a very long wire!

[22:54] <g6uim> Might move the antenna one last time before I go to bed later. Can't do it in the morning as it's above a room that will be occupied by my brother who is doing a nightshift
[22:54] <daveake> Adam012 One of the problems is that your code is sending a message and then expecting the reply to *immediately* land at the Arduino. If there's any delay then your the for loop that receives characters may well receive too few or none at all. You need to think about how that /should/ work.
[22:55] <g6uim> I don't live in Torquay Geoff so I will be entirley innocent

[22:55] cuddykid (~acudworth@92.40.254.10.threembb.co.uk) left irc: Quit: cuddykid
[22:56] <daveake> The correct solution is code that waits up to (some period, say 1 second) for the reply.
[22:56] <daveake> That code should complete when it receives the reply OR that period elapses, whichever comes first
[22:57] <Adam012> We used while(!gps_set_sucess) to wait.
[22:57] <nigelvh> Seconding daveake. Having to get any input is a VERY tricky situation that can easily go wrong. Make sure the logic here is well vetted.
[22:58] <Adam012> So we need a wait and then a check to see if anything has been received?
[22:58] <daveake> Adam012 No you're not. Just read your loop() code
[22:59] <daveake> You need a loop that has 2 tests in the for() bit. One test for "have we timed out yet?" and another for "have we got a complete reply yet?"
[22:59] <Adam012> Ah, right. It's the checking for a complete reply that I'm not certain about.

[23:01] <daveake> well the cheap and dirty method (I wouldn't stoop that low but hey ..) is to assume the first n bytes are your reply
[23:02] <daveake> A better method is to analyse the received bytes, looking for the "start of reply" marker, picking up the "length of reply" byte, and counting from there
[23:02] <Randomskk> a state machine!
[23:02] <Randomskk> with timeout states.
[23:02] <nigelvh> ^^ and if these things don't happen in a reasonable timeframe, do something else.
[23:03] <daveake> Indeedy
[23:03] <Randomskk> state machines are excellent
[23:03] <Randomskk> and not really that hard to write either
[23:03] <daveake> Though I'd guess only a few percent of trackers do this
[23:03] <Randomskk> yes indeed
[23:03] <Randomskk> they are great for parsing nmea too
[23:03] <Adam012> So check the first two characters in the string to make sure their values are expected and check that the length of string received matches the expected length?
[23:04] <nigelvh> I would read available bytes UNTIL you get the characters you expect, and check that you have the whole string. OR the timeout is reached.
[23:05] <Adam012> I'm learning the Arduino code as I go and the learning curve has been very steep which is why I thought I would seek a little advice.
[23:05] <nigelvh> If you don't get the chars you expect anywhere in the string OR you don't get the complete string OR the timeout occurs, you need to be able to handle that without hanging.

[23:07] <nigelvh> Check that it's reasonable in value. If it shouldn't be negative, make sure it's not negative. If it shouldn't be above a certain value, check that it isn't

[23:08] <Randomskk> seconds can be equal to 60 fwiw
[23:08] <nigelvh> Yes
[23:08] <Randomskk> or even 61 in unusual cases
[23:08] <nigelvh> On a leap second.
[23:08] <Randomskk> (double leap second)
[23:08] <daveake> Yeah thought you might say that :)
[23:09] <Randomskk> the 61 case is rare enough that a lot of programming languages don't actually support it
[23:09] <daveake> was hoping to get away with it
[23:09] <Randomskk> we spent a long time deciding what exactly to do about this in habitat actually
[23:09] <Randomskk> can't remember the outcome
[23:09] <Randomskk> probably going overkill for Adam012 here though
[23:09] <nigelvh> But the idea is that you have a data field that should have a certain kind/value of information in it, so check that it fits

[23:09] <Randomskk> never been a double leap second before daveake
[23:10] <nigelvh> Adam012, doesn't matter what the field is, there should be a reasonable range of values, so make sure it fits.
[23:10] <Randomskk> https://github.com/ukhas/habitat/blob/develop/habitat/utils/rfc3339.py#L94-L100 there's the information on habitat's support for leap seconds
[23:10] <Randomskk> so 60 or 61 actually get rejected due to other technical interests
[23:11] <daveake> Sensible
[23:11] <DanielRichman> poo, I spelt blissfully wrong. How did that happen
[23:11] <nigelvh> Randomskk, missing one data point for a leap second is unlikely to be an issue.

[23:12] <nigelvh> Exactly
[23:12] <Adam012> right, a quick check that length of string received matches length of string expected and a timeout of 3 seconds by comparing time spend in the loop vs time the loops was entered with a return in each instance.
[23:12] pjm (~pjm@uhfsatcom.plus.com) left irc: Read error: Connection reset by peer
[23:12] <Randomskk> we still wanted to try
[23:12] <DanielRichman> it's a shame that unix timestamps don't support them, but the convenience of being able to continue using them is far greater
[23:12] pjm (~pjm@uhfsatcom.plus.com) joined #highaltitude.
[23:12] <DanielRichman> second them should be 'timestamps'
[23:12] <Randomskk> Adam012: sounds sensible

[23:13] <nigelvh> Adam012, exactly, but also check that the start chars are what you want. You may need to read through a bit, sometimes you get garbage or null serial bytes before anything else comes in.
[23:14] <Adam012> Ah, what's the integer value for a null serial byte >0?
[23:14] <nigelvh> I wouldn't bother checking if it's null, I'd check that it is/isn't what you want.
[23:14] <Randomskk> ublox modules reply with two bytes before any data
[23:14] <Randomskk> I forget what they are. something amusing
[23:14] <Randomskk> I think it's 'U' and 'B'
[23:15] <nigelvh> But a null byte is 0x00
[23:15] <Randomskk> so basically after sending the request for a packet
[23:15] <Randomskk> read in every byte until you see 'U' (which is probably the first byte you see, but if you get a null first, you can discard it this way)
[23:15] <Randomskk> then count bytes after the 'U' until you get as many bytes as you expected
[23:15] <Randomskk> then you're done
[23:15] <Randomskk> and parse that data
[23:15] <nigelvh> OR timeout
[23:15] <Randomskk> or timeout. indeed.
[23:16] <Adam012> It says the header is 0xB5 0x62 but I thought this was just on polling commands
[23:16] <Randomskk> it's on all UBX-protocol responses iirc
[23:16] <Randomskk> worth checking, it's been a while
[23:16] <nigelvh> Test iot
[23:16] <nigelvh> it*
[23:16] <Adam012> Will do!
[23:16] <daveake> There's a length byte too isn't there?
[23:17] <Randomskk> yes. after U and B
[23:17] <daveake> Cool, so Adam012 read that length byte and then count bytes till you get the right number (which might be Length+1 ... check the manwell)
[23:18] <daveake> Also check the Length byte is reasonable first :)
[23:18] <Adam012> Header 0xB5 0x62, then Class ID 0x01 0x21, then a length byte of 20
[23:18] bertrik_ (~quassel@rockbox/developer/bertrik) left irc: Remote host closed the connection
[23:19] <daveake> It's best to read the length byte rather than assume. There might be circumstances where the message you're receiving is something other than the reply you were expecting
[23:19] Laurenceb_ (~Laurence@host86-178-5-116.range86-178.btcentralplus.com) left irc: Ping timeout: 272 seconds
[23:19] <Randomskk> haha all this best advice
[23:20] <Adam012> Could we just set up the reading subroutine so that it read until 0xB5 was received and then started writing to the string? Perhaps build in a timer that restarts the whole process if it has no success in the first 3 seconds
[23:20] <Randomskk> one day I'll write good payload code.
[23:20] <Randomskk> so far all the payload code I've ever written has been started less than 24 hours before launch. sometimes much less
[23:20] <daveake> hah
[23:20] <Upu_M0UPU> lol
[23:20] <Randomskk> my favourite by far is the stm32f4 where I did the whole messing about with printing floating point degrees
[23:21] <Randomskk> by using the chip's FPU and actual real doubles and the full printf with %d
[23:21] <Randomskk> yay 1MBit ROM
[23:21] <Randomskk> so easy to write
[23:21] <daveake> luxury. When I were a lad ...

[23:22] <Randomskk> does he have a beard
[23:22] <nigelvh> I've decided that I'm happy just doing the hardware.
[23:22] <nigelvh> Yes
[23:22] <Randomskk> I bet he does >_>
[23:22] <Randomskk> hah
[23:22] <Upu_M0UPU> obligatory
[23:22] <nigelvh> He's a retired boeing engineer
[23:22] <nigelvh> I'm happy to use C.
[23:22] <daveake> my first 'puter was a Z80 home brew with toggles, so I programmed by remembering the hex op codes and converting to binary. Anyway ... back to now :)
[23:23] <Upu_M0UPU> poke 53280,0
[23:23] <nigelvh> A buddy of mine is building a Z80, and programs the flash with an arduino, the boots the Z80
[23:23] <fsphil> who turned out the lights!
[23:23] <Upu_M0UPU> haha
[23:23] <Adam012> Thanks for all of the good advice. We'll go away and try again.
[23:23] <daveake> excellent
[23:23] <Upu_M0UPU> thanks I was just typing someone on here must know what that does
[23:23] <fsphil> you need poke 53281,0 for maximum effect
[23:23] <Upu_M0UPU> or cycle them :)
[23:23] <daveake> Does that blow up the monitor?
[23:24] <jcoxon> okay, so whats the plan for monitoring atlas overnight?
[23:24] <Upu_M0UPU> close changes border/screen black
[23:24] <Upu_M0UPU> I'm leaving it on auto but its likely to drift out of range,
[23:24] <Upu_M0UPU> G6UIM
[23:24] <Upu_M0UPU> whos is probably the best bet is leaving it running
[23:24] bertrik (~quassel@rockbox/developer/bertrik) left irc: Remote host closed the connection
[23:24] <jcoxon> my radio setup can be vnc'd into
[23:25] <GMT> I'm tempted to leave it all running too.
[23:25] <nigelvh> When it drifts over to washington I'll listen for it.
[23:25] <Upu_M0UPU> well Darkside is awake
[23:25] <Upu_M0UPU> :)
[23:25] <Upu_M0UPU> lol nigelvh
[23:25] <Upu_M0UPU> get on a Global Tuner and make yourself useful :)
[23:25] <nigelvh> You guys just need to do the reverse of the california group
[23:25] <GMT> there's a globaltuner in Toulouse which could prove useful tomorrow
[23:25] <Upu_M0UPU> we can do it
[23:25] <fsphil> I was hoping it would come back around into range of me :)
[23:25] <nigelvh> If you guys have good enough aim I'll even recover it for you.
[23:26] <Upu_M0UPU> at certain times of the year
[23:26] <Upu_M0UPU> mainly ends up over Canada though
[23:26] <fsphil> I'm definitely going to try that
[23:26] <nigelvh> If it's south enough canada should still be fine.
[23:26] <fsphil> although I'll need a US'ian HX1
[23:26] <nigelvh> I'm on a good hill
[23:27] <Upu_M0UPU> got those fsphil
[23:27] <Upu_M0UPU> anyway working on a freq agile version
[23:27] <Upu_M0UPU> anyway cheers jcoxon
[23:27] <Upu_M0UPU> enjoyed that
[23:27] <Upu_M0UPU> its currently 550km from me and still strong, I'll leave everything on. Night all
[23:27] <fsphil> g'nite!
[23:27] <nigelvh> Evening
[23:27] <Adam012> Goodnight all!
[23:28] <g6uim> yes am leaving mine running although I cannot turn the beam so might have to switch to a colinear if it goes out of the path of my SW pointing beam

[23:28] <Upu_M0UPU> btw the rotator is 20' off its current position and its still a strong signal
[23:28] <fsphil> I suspect a launch here would go into northern canada
[23:28] <Upu_M0UPU> point the beam 20' off its current position to where its going g6uim
[23:28] <fsphil> I'm further north than St.Johns
[23:28] <Upu_M0UPU> should still decode
[23:28] <Upu_M0UPU> anyway really night
[23:29] <fsphil> but it does have the advantage of minimum atlantic ocean
[23:29] <nigelvh> fsphil, just choose the right winds and you'll be set.
[23:29] <fsphil> and if it goes north enough, greenland
[23:29] <fsphil> timing launch permission, and the proper winds, is tricky :)
[23:29] <fsphil> although the winds last time lasted a few weeks
[23:30] <nigelvh> Bah, just take care of it.
[23:30] <fsphil> but definitely going to try it
[23:30] <nigelvh> I'll be a'listenin'

[23:31] <fsphil> my project before I started HAB'ing, was to build a robot boat to sail to st.johns from here

[23:32] <fsphil> as/at
[23:33] <gonzo___> any aprs expetrs in the chan?
[23:33] <nigelvh> What's up?
[23:33] <gonzo___> going to try uplinking to ATLAS
[23:33] <nigelvh> Ok.
[23:33] <nigelvh> People were saying earlier it wasn't working
[23:34] <jcoxon> gonzo___, i didn't get it working even at 1km range
[23:34] <jcoxon> (after launch)
[23:34] <gonzo___> still willing ton try
[23:34] <jcoxon> what OS?
[23:34] <GMT> Right, I'm off to bed, but I'm leaving this lot running o/night. GN all, play nicely.
[23:34] <gonzo___> OS! hardware modem
[23:34] <fsphil> nite GMT
[23:35] <fsphil> haha
[23:35] <jcoxon> oh nice, but what OS you connecting the tnc to?
[23:35] <gonzo___> have a good old fashioned tnc and a dumb term
[23:35] <gonzo___> well ok, hyoerterm
[23:35] <jcoxon> basically the packet needs to complain a message with # each site
[23:35] <jcoxon> side*
[23:35] <jcoxon> e.g. #hi from gonzo#
[23:35] <gonzo___> a std unproto packet
[23:35] <jcoxon> yeah
[23:36] <gonzo___> whcallsigh is it listening for?
[23:36] <jcoxon> it isn't
[23:36] <jcoxon> it'll decode anything
[23:36] <jcoxon> and extract out anything between the two #'s
[23:36] <gonzo___> so any ax25 packet with ~xxx~ somewhere in will do?
[23:36] <gonzo___> ok, will try again
[23:37] <fsphil> I wonder why it's not working though
[23:37] <jcoxon> desensitised rx?
[23:37] <nigelvh> jcoxon, what code are you using to decode the APRS?
[23:37] <jcoxon> temp drift
[23:37] <jcoxon> customised arduino tnc code
[23:37] <nigelvh> Ah.
[23:38] <jcoxon> it worked on the ground, thought it was worth trying :-

[23:39] <nigelvh> Didn't recover that payload either, so failure analysis was difficult...
[23:40] <jcoxon> oooo finally the turn south
[23:40] <gonzo___> what's the rx ant?
[23:40] <daveake> Same with the Space Ted flight I did with Darkside. Interference from a video camera that time
[23:40] <jcoxon> slimjim above the payload
[23:41] <gonzo___> vertical
[23:41] <jcoxon> yeah
