[02:07] <KF7FER> should I wave my dollar bills now?
[02:07] <KF7FER> it always works at the strip club
[02:08] <arko> im pretty sure the Dragon V2 is going to be worth more than you can physically wave
[02:09] <arko> though, i'd be impressed if someone could
[02:09] <KF7FER> so have you read the comments at the bottom of the page? You'd think these people funded the launch or something
[02:10] <arko> nah
[02:10] <arko> i imagine they are like youtube comments
[02:10] <arko> background is getting louder
[02:10] <arko> go live damn it
[02:10] <KF7FER> it's not just me?
[02:10] <KF7FER> and yes... youtube comments are if you're really bored and have no life
[02:11] <KF7FER> yes! more cowbell!
[02:11] <KF7FER> or is it cow bell?
[02:11] <arko> i think thats just you
[02:11] <arko> i hear no cow bell
[02:12] <KF7FER> I was actually talking about the comments but yes, I'm sure it's just me.

[12:31] <UpuWork> nothing seen
[12:31] <daveake> Last time I had a strong signal whilst waiting for a launch, I'd forgotten to switch off my own tracker :p
[12:31] <amell> 575Hz, 1150Hz and 1700Hz on the waterfall - what on earth could it be.
[12:32] <fsphil> I've never done something so silly </lie>

[12:33] <mfa298> I think I've heard a lot of noise on .075 before from my location. I think a lot of ISM devices seem to like the lower frequencies
[12:33] <amell> its really loud
[12:34] <amell> i guess i need to go and turn things off to find the source of it
[12:35] <amell> hmm! Its still there even when i change frequency.
[12:35] <daveake> Yeah, much better to use .650 :p
[12:35] <amell> i dont understand this
[12:36] <amell> the same noise is there at 475.650
[12:36] <mfa298> or build your payloads faster so you're on the ntx2b
[12:36] <mfa298> amell: it's not just the centre DC spike you get on some dongles is it ?
[12:37] <amell> it wasnt there a couple of weeks ago
[12:37] <daveake> mfa298 I need to lose my old ones faster :)
[12:39] <amell> this is disturbing - http://www.dildo-generator.com/
[12:39] <amell> order 3D prints once you have completed your design.
[12:41] <amell> http://i.imgur.com/8iqZ7PG.png - why is there a spike?
[12:42] <mattbrejza> do you have an atenna attached?
[12:42] <mattbrejza> is it still there with an antenna?
[12:42] <mattbrejza> does it move if you change the LO?
[12:42] <amell> yes its antenna connected.
[12:42] <amell> LO?
[12:43] <mfa298> that looks like the DC spike you get on some rtlsdrs - it always stays at the centre of the watefall
[12:43] <mattbrejza> does it go if you remove the antenna?
[12:43] <mattbrejza> LO might be called VFO in ham terms
[12:44] <amell> nope. actually theres no change if i disconnect the antenna
[12:44] <mfa298> amell this might help http://ukhas.org.uk/_media/guides:sdr2.png
[12:44] <G8APZ> LO = Local oscillator
[12:45] <G8APZ> well it isn't an actual signal coming via the antenna.... so it is internally generated
[12:45] <amell> it makes no difference if the antenna is connected or not.
[12:45] <amell> i think theres something wrong with my SDR
[12:47] <mfa298> amell: it's to do with how some rtl chips work - its quite normal - see the image I liked above!!!
[12:48] <amell> yep ok, but i didnt have this big spike the last time i used it,
[12:48] <mfa298> it's not a real signal so won't move and won't change if you remove the antenna. It may change in strength if you adjust the gain on the rtl or if you start getting strong signals
[12:49] <amell> going to get meter out. wondering if antenna is shorted
[12:50] <mfa298> an easier test might be to tune down to the braodcast band/ airband or marine band.
[12:50] <mfa298> although you may need to remove the habamp if you've got one for those bands
[12:50] <gonzo_> what is the antenna?
[12:51] <gonzo_> depending on the design, it may be DC short anyway.
[12:55] <amell> its an x50, no habamp in yet, rp-sma issue
[12:55] <gonzo_> Launch?
[12:55] <UpuWork> what frequency ?
[12:56] <UpuWork> oh I se it

[13:09] <UpuWork> yeah he put enough gas in it
[13:10] <mattbrejza> i think it has a spot backup though

[13:54] <amell> appreciate it if anyone can tell me how to improve
[13:54] <UpuWork> I'd have set off already :)
[13:54] <amell> got another good decode whoopee
[13:54] <fsphil> 368km. this one is actually fairly close
[13:57] <fsphil> been a while since I've heard rtty. a lovely sound (for the first few minutes anyway)
[13:58] <g8fjg_ron> your noise floor seems quite high? -42?...haven't got all the gains at 11 have you...
[13:58] <PE2G> First green at 594 km -0.4 deg
[13:58] <daveake> especially lovely when it appears out of the noise when chasing a landed flight
[13:58] <fsphil> yes
[13:58] <amell> g8fjg_ron: talking to me?
[13:58] <fsphil> had that on the bbc flight. the signal totally disappeared
[13:58] <bertrik> 446.9 km here, but no greens yet
[13:59] <daveake> I think most have mine that's happened
[13:59] <fsphil> when we got near it and drove over a hill, those lovely tones reappeared
[13:59] <daveake> :)
[13:59] <fsphil> I've only done three chases
[13:59] <daveake> Also, if it's going far, you can't really chase can you?
[13:59] <fsphil> not really
[13:59] <daveake> So yours will have landed fairly close
[13:59] <fsphil> most of mine have been release and track
[14:00] <g8fjg_ron> amell yes,,,I compared a rtl dongle with a funcube some time ago, it needed a preamp,,with filter, (most important ) to compete
[14:00] <amell> ok. i dont have a power supply set up yet
[14:00] <fsphil> shame too, the chasing is the fun part
[14:00] <fsphil> oh yes, I was going to go out and see if I can find that met sonde

[14:10] <mfa298> g8fjg_ron: the habamp has a 434MHz saw filter in it. It's designed for tracking balloons.
[14:11] <g8fjg_ron> so that should take care of out of band overload

[14:12] <amell> well, i cant find it with the habamp on.
[14:12] <amell> anyone want a habamp? I have one for sale
[14:12] <fsphil> you won't get anything through the habamp if it's not powered correctly

[14:12] <fsphil> or you've connected it backwards
[14:12] <amell> i have 7.5Vdc on the habamp
[14:12] <amell> in is aerial, out is dongle right?

[14:14] <fsphil> my habamp had no labels so I can't help you there amell :)
[14:14] <fsphil> it's one of the early models
[14:15] <DutchMillbt> nice distance PE2G
[14:15] <fsphil> in and out are bad descriptions
[14:15] <g8fjg_ron> amell , does the noise floor go "up" when you connect the amp?
[14:15] <fsphil> it should be "antenna" and "radio"
[14:15] <PE2G> DutchMillbt: Been a long time since I saw 600 km here
[14:16] <amell> when i turn the power to the habamp on i get a nice curved white line on the waterfall
[14:16] <amell> then it disappears
[14:18] <DutchMillbt> yep PE2G your @ record number 7 : http://ukhas.org.uk/general:uk_records?s[]=records ;-)
[14:19] <amell> am i supposed to have hardware AGC on?

[14:23] <amell> well i seem to get better reception without the habamp. I need to get on with other stuff now so will have to investigate another time
[14:23] <Hiena> They installed the transmitter in the middle of an eartquake.
[14:23] <G8APZ> some confusion in the GPS co-ords when zooming in on the map!
[14:24] <amell> -24m/s is going to hurt someone. Hope that chute works
[14:24] <daveake> It's fine
[14:24] <mfa298> amell: it's worth playing with the various gain controls within gqrx and see what provides good settings.
[14:24] <daveake> Take rate @ 20km and divide by 4
[14:25] <amell> oh yeah, air density increases.
[14:25] <amell> got it
[14:25] <daveake> it's a tad fast
[14:25] <amell> its a 5 foot chute apparently]
[14:25] <daveake> Sounds about right for 2.5kg
[14:26] <daveake> Worth remembering with the heavier payloads that even a small increase in landing speed is quite a lot more energy
[14:26] <amell> looks like its coming down in fields.
[14:26] <amell> so no worries most likely

I'm thinking the gang over here in the US probably mostly use the HX1's... *granted there is an frequency issue as most are on the aprs freq*... but I'm just curious in general

[15:45] <adamgreig> uhm... you realise the vast majority of people here use or used an ntx2 radiometrix module on an SSB mode?
[15:45] <adamgreig> perhaps you mean something different by "SSB modes"
[15:45] <aadamson> of course I do... I just wondered if before those did anyone experiment with the HX1's
[15:46] <aadamson> and no I did mean *SSB modes - RTTY, MFSK, etc*
[15:46] <adamgreig> well given as an HX1 would be illegal to fly in the UK
[15:46] <adamgreig> I doubt anyone has flown one here
[15:46] <adamgreig> but they have the same interface as an NTX2, so...
[15:46] <aadamson> I suspect this group is larger than just the UK? (people on the IRC channel)?
[15:46] <adamgreig> fair enough
[15:47] <aadamson> adamgreig, where is there NTX2 code and I'll take a look and see if it's *portable* to the HX1;s
[15:47] <adamgreig> well basically it's the same as an ntx2 and there's no shortage of code for that
[15:47] <adamgreig> it's not even portable
[15:47] <adamgreig> it's just the same
[15:47] <aadamson> HX1's are available in 144.390. 144.800 and a couple of other freq

[15:49] <craag> habduino uses a HX1 for APRS, and an LMT2 for 70cm RTTY
[15:49] <aadamson> ok, this may get me started - http://ukhas.org.uk/guides:linkingarduinotontx2?s[]=rtty
[15:49] <craag> LMT2 has been replaced functionality wise with the NTX2B now
[15:50] <aadamson> craag, ok, I'll look at that too
[15:50] <craag> LMT2 had tcxo and programmable frequency - both of which can now have with Anthony's special NTX2Bs
[15:50] <aadamson> do I remember a conversation around a frequency agile radiometrix module? was it only for 432mhz
[15:50] <UpuWork> LMT2 is frequency agile
[15:50] <craag> Yeah the LMT2 is frequency agile as standard
[15:51] <UpuWork> the NTX2B I sell is frequency agile but won't be if you got it anywhere else
[15:51] <UpuWork> I may at some point redo the Habduino to work with the NTX2B
[15:51] <aadamson> ah, cuz it's *flash changeable only*?
[15:51] <UpuWork> no because Radiometrix don't sell it as frequency agile
[15:51] <aadamson> ah
[15:51] <aadamson> ok
[15:52] <UpuWork> they kindly let me modify it and sell it on as FA
[15:52] <aadamson> the impetus for the question... I'd really like to see more folk over here use the SSB modes (I don't care on what frequency)... but no-one has led the horse to water so to speak to show/give/provide code to do that
[15:53] <adamgreig> not really the best metaphor is it
[15:53] <adamgreig> doesn't WB8ELK fly rtty and stuff?
[15:53] <bertrik> I guess the SSB modules are a lot more expensive
[15:53] <aadamson> yeah but he's using rfm's
[15:53] <aadamson> silabs
[15:53] <adamgreig> uh huh...
[15:53] <adamgreig> do you know what's inside the ntx2b, the mtx2, etc etc?
[15:53] <UpuWork> he's used NTX2's in the past
[15:54] <aadamson> no I didn't know that's what was inside them
[15:54] <UpuWork> SI4460
[15:54] <aadamson> just no interface to the programming locgic
[15:54] <UpuWork> older ones were all analogue
[15:54] <adamgreig> the NTX2 itself is wonderful, it is kind of a shame they swapped out, but I guess it makes sense
[15:54] <aadamson> ah... got it, only one I played with was an hx1
[15:54] <adamgreig> still a glorious piece of engineering to open one of those up
[15:54] <aadamson> and I suspect most arduino guys over here are using that
[15:54] <UpuWork> I'll pass on your compliments to the chap who made it adamgreig :)
[15:54] <aadamson> the finally fixed the peremphasis issue with it
[15:54] <jonsowman> mine too
[15:55] <mattbrejza> isnt the reason noone uses "SSB modes" because there is minimal people to listen?
[15:55] <mattbrejza> APRS is more of a pita than rtty
[15:55] <aadamson> mattbrejza, that's relative. there is ONE HUGE advantage to ARPS
[15:55] <jonsowman> the guy who designed the ntx2 has my utmost respect
[15:55] <jonsowman> really nicely done
[15:55] <aadamson> mimimal current demand
[15:55] <adamgreig> uhm what
[15:55] <aadamson> aprs isn't 100% duty cycle
[15:56] <aadamson> for as long as the SSB modes
[15:56] <adamgreig> do you mean "it's a higher baud rate and you don't transmit continuously"?
[15:56] <aadamson> 1200 baud trumps most of the SSB modes
[15:56] <aadamson> correct
[15:56] <adamgreig> uhm
[15:56] <adamgreig> except for the 1200 baud SSB modes?
[15:56] <adamgreig> or, you know, the 2400 baud SSB modes. I hear they're about half the duty cycle again!
[15:56] <mattbrejza> well a 300baud rtty sentence takes like 3sec to transmit so i dont really see your point
[15:57] <aadamson> yep, and those are ever *more* rare than most of what people use
[15:57] <adamgreig> you need a handful dB more transmit power to get the same SNR on AFSK as FSK at the same baud rate anyway, so if anything it's worse from an energy perspective
[15:57] <mattbrejza> well when was the last time a payload ran out of battery? (a up-down one)
[15:58] <aadamson> adamgreig, from that perspective you are correct
[15:58] <adamgreig> so when you said APRS has "ONE HUGE advantage", minimal current demand
[15:58] <aadamson> mattbrejza, I think you have my perspective wrong.... I'm ALL FOR the SSB modes
[15:58] <aadamson> I'm trying to figure out a way to get more people interested
[15:58] <adamgreig> that was just not quite right?
[15:58] <aadamson> and to do that you *have to lead the horse to water*
[15:58] <adamgreig> but you can't make it drink!
[15:59] <aadamson> you are absolutely correct
[15:59] <craag> the info is out there on the wiki
[15:59] <craag> tons of people publish their code
[15:59] <aadamson> but it's a hill I'm willing to take a run up for kicks and giggles
[15:59] <aadamson> thank craag I'm looking at that now
[16:00] <mattbrejza> i dont really think youll get people to move aprs->rtty when aprs works just fine
[16:00] clopez (~tau@neutrino.es) left irc: Ping timeout: 240 seconds
[16:00] <aadamson> mattbrejza, most complain that while aprs works fine, it's a *post tense* learn that it didn't
[16:00] <aadamson> and they would like to understand a more *real time* - live mechanism
[16:01] <mattbrejza> er wat
[16:01] <aadamson> Just look at how you guys used it this morning.... "oh, look the platform reset, gps powered off, oh, it's back
[16:01] <aadamson> "
[16:01] <aadamson> can't do that very easily with aprs
[16:01] <G8APZ> aprs is not licence free either
[16:02] <G8APZ> 434.600 is ISM
[16:02] <aadamson> takes no license to *listen*
[16:02] <mattbrejza> well in the US i dont think 434 is ism
[16:02] <aadamson> it's not
[16:02] <aadamson> only 900mhz
[16:02] <craag> Right, so just build a 300 baud rtty tracker on 2m and cofly it with aprs?
[16:02] <aadamson> sure
[16:02] <aadamson> or better, you build a tracker like I did that is multimode
[16:02] <G8APZ> ISM makes sense here since you cannot fly APRS in UK
[16:02] <aadamson> multi frequency, etc
[16:02] <aadamson> G8APZ, I completely understand that issue in the UK
[16:03] <craag> aadamson: Ok, so what's the fuss about porting ntx2 code?
[16:03] <aadamson> craag, I'm trying to think of ways to allow *others - no me* to *experience* this with what they might have already - radiometrix modules
[16:04] <craag> Sure
[16:04] <aadamson> that's all I'm trying to do
[16:04] <craag> Is 434 in ham band in the states?
[16:04] <aadamson> no, hence my question about frequency agility with the ntx/hx/etc
[16:04] <aadamson> actually... yes
[16:04] <aadamson> duh I forget its 430-450
[16:05] <aadamson> so much for my *extra* :)
[16:05] <craag> Ok, so fly an NTX2 with callsign == ham callsign
[16:05] <craag> done, easy
[16:05] <G8APZ> assuming that airborne TX is allowed on 434 in USA!
[16:05] <aadamson> yep, I just don't think people over here know that can be done... maybe I'm too new and don't know, but I'm happy to splain that to them :)
[16:05] <aadamson> is it
[16:05] <aadamson> it is

[16:06] <craag> Slap an ntx2, arduino pro mini, ublox together
[16:06] <G8APZ> 10mW goes a long long way from 30km up!!
[16:06] <aadamson> craag, that's the through... my flight tonight will be my new tracker :)
[16:06] <aadamson> so it doesn't count
[16:07] <G8APZ> my best reception was over 700km from a flight that went to 40km
[16:07] <craag> Ok cool
[16:07] <craag> But if you want other people to try, make a demo tracker
[16:07] <craag> I have an arduino pro mini, ntx2b, ublox - ugly bugged onto 3x AAA
[16:08] <craag> As a demo tracker for talks
[16:08] <aadamson> yep... I think I'll try that... let me get with Bill and see what he's doing (might be the easiest way to get an ntx2 - short of that get one from Anthony)

[16:13] <aadamson> hey on another topic and I suspect due to your 10mW power limitation you haven't but has anyone done anything with a PA on the Silab parts?
[16:13] <aadamson> I had a question in email about doing 300mW with one... guess I'll have to see what I can find for a small PA
[16:14] <aadamson> mattbrejza, the HX1's are on the us (or EU) packet frequency
[16:14] <aadamson> so putting MFSK on there might not be too acceptable
[16:14] <mattbrejza> oh right
[16:14] <mikestir> aadamson: I was thinking about that doing a standalone APRS tracker for ground-based operation, so maybe as much as a watt
[16:15] <craag> aadamson: What's the EU packet freq used for over there?
[16:15] <aadamson> mikestir, if you find anything in your looking let me know... I've seen them use the 7W mitsubishi module, but just looking for something with about 300mW would be acceptable
[16:16] <aadamson> craag, repeater inputs I believe
[16:16] <aadamson> 144.800?
[16:16] <craag> yeah
[16:16] <mikestir> maybe a single stage class E would be enough
[16:16] <aadamson> yeah, that's the inputs on the low side in 2mtr freqs
[16:16] <craag> ah ok, so probably not so suitable
[16:16] <craag> Although we use 70cm input freqs over here :P
[16:16] <aadamson> one half of the us uses low in the others high in so it would be either an input or an output I believe... I'd have to check
[16:17] <aadamson> our 70cm is high and low in as well, it's really strange
[16:17] <aadamson> wish it were common, but it's not
[16:17] <aadamson> and I wish the world would go digital :)
[16:18] <aadamson> I have a network for probably 20 ham repeaters all on NXDN - 4FSK so they work both analog and digital
[16:18] <aadamson> 20 repeaters around the US, CA and one in turkey of all places :)
[16:18] <craag> I saw someone has put a freedv modem on an stm32
[16:19] <aadamson> mikestir, yeah so in theoy if you could derate the 4x6x so you weren't needing to run it at max and then PA it up to 300mW that would be awesome
[16:19] <mattbrejza> you can get 1W PA ICs from analog
[16:19] <mattbrejza> not sure if they go down to 144MHz though
[16:19] <aadamson> craag, is that the digital HF stuff that started using a propietary codec, then moved?
[16:20] <craag> aadamson: No, FOSS from the start, based on Codec2
[16:20] <craag> But yes, primarily HF
[16:20] <aadamson> craag, ah... ok,,, yeah codec2 the codec looking for a purpose
[16:20] <aadamson> amazing, that's gone no-where fast
[16:20] <mikestir> you'd get upwards of 10dB gain out of a conventional (class C) transistor PA, which would be enough if driven from the 4460 running at 100mW
[16:21] <craag> It's always going to have slow take-up with no commercial backing
[16:21] <aadamson> I thought Yaesu was going to do something with it on their digital platform, but NO, they came out with something not compatible with anything

[16:23] <craag> I've seen hams using dPMR, but more dstar
[16:23] <aadamson> hehe *sounds like the world at the moment*... oh and I have no stomach for dstar - to have an organization that can *ban* hams for life from using the mode isn't how ham radio works
[16:23] <aadamson> IMHO
[16:24] <aadamson> and that's how the US Trust works (and which is in bed with Icom)
[16:24] <craag> Yep, I share the dislike
[16:24] <aadamson> besides if you ever hear DMR or NXDN you'll *never* want dstar again
[16:24] <aadamson> besides they can claim all they want, but it is *NOT* sub 10khz bandwidth
[16:25] <aadamson> it's approx 10.5-12 where as DMR is 2 time slot at 12 and NXDN is 6.25khz
[16:26] <aadamson> and someone should have been shot to not include the FEC bits in the voice datastream (only data), to get rid of the R2D2... but time for me to get off that horse (keeping with the metaphor :))
[16:27] <craag> erm AMBR includes its own FEC
[16:28] <aadamson> it does, but they don't use it
[16:28] <aadamson> thats been the raging debate
[16:28] <aadamson> it's only enabled when they do high speed data
[16:28] <aadamson> in voice, it's not used hence the R2D2 that you hear
[16:28] <craag> The FEC is done in the AMBR decode
[16:29] <craag> it's 3600bits, containing 2400bits voice and 1200bits FEC
[16:29] <aadamson> craag, remember that dstar uses the *old* codec
[16:29] <aadamson> if you read the spec, it's not used for voice, I don't know how, don't care, but that's why they have R2D2
[16:29] <craag> Yeah, I'd have to dig out my sources but im pretty sure it had FEC
[16:29] <craag> hence why the overlay D-STAR spec only does FEC on the data
[16:30] <aadamson> the AMBE2+ that DMR/P25/NXDN, etc use same bitrate, narrow channel, and no digital artifacts and lower bandwidth needs
[16:30] <aadamson> anyway... I need to go get my fill station together... got a balloon to fly... if you find that link for the freedv stuff shoot it my way if you would please
[16:30] <aadamson> ?

[16:50] <Laurenceb_> some kind of digital voice transceiver
[16:50] <LeoBodnar> all this SSB vs AFSK discussion, I am completely lost
[16:50] <LeoBodnar> people fly balloons
[16:50] <LeoBodnar> they want to find the payload
[16:51] <LeoBodnar> they do
[16:51] <LeoBodnar> it just works
[16:52] <LeoBodnar> why change modulation for the sake of changing the modulation?
[16:52] <LeoBodnar> I must have missed something important
[16:52] <aadamson> LeoBodnar, no, no, no... I'm not trying to do any of the above
[16:53] <aadamson> I'd like to incent the gang over here in the US to try the SSB modes and to do so, if I can find a way to make it easy for them (on their existing hardware for example), I might be able to get some to try it.
[16:53] <aadamson> There are a million issue obviously, none the least the type hardware they might be using
[16:53] <aadamson> it's just a way to see if a more *live, realtime* network could be created over here in the US
[16:53] <aadamson> that's all I'm after
[16:53] <LeoBodnar> what could be livlier than APRS?
[16:54] <LeoBodnar> it's 2 sec latency
[16:55] <LeoBodnar> fun is one thing, practicality is another
[16:55] <aadamson> I guess what I'm really after is the *fun* aspect moreso than the live one... yes it's live, but it's a different live
[16:55] <aadamson> Ok, I completely agree with that comment
[16:56] <LeoBodnar> you have better chance exciting hams about balloons than baloonists about some esoteric modulation mode
[16:56] <aadamson> but I hear time again again over here that people are wanting a *better* experience in tracking and from my perspective the *crowd* way of doing it seems a better experience
[16:56] <LeoBodnar> that also has 10-100 times less chance to be received
[16:56] <LeoBodnar> in the US
[16:56] <aadamson> yeah, that I do understand...
[16:57] <aadamson> it's just a side effort really... today I plan to launch W7QO-6 :)
[16:57] <aadamson> we'll see how that goes...
[16:57] <aadamson> I'm a little *heavy* in prototype form that I'd like, but it is what it is
[16:57] <aadamson> 22grams
[16:57] <aadamson> all in
[16:57] <Laurenceb_> photos?
[16:57] <LeoBodnar> you are mistaken thinking that USA and UK ballooning scene are completely detached from each other
[16:58] <aadamson> LeoBodnar, not mistaken at all... I'm pretty sure they are *attached* actually
[16:58] <aadamson> Laurenceb_, hang on

[17:00] <arko> B knockoff?
[17:00] <Laurenceb_> whats the vertical antenni?
[17:00] <aadamson> I forgot to get some black PVC heatshrink, so this morning I ran down to a place and got some black PVC cap shinks
[17:00] <LeoBodnar> there is no point in force-feeding USA guys something just because we are using it here. Invent something completely new and we will all copy it if we need it.
[17:00] <aadamson> they will work
[17:01] <aadamson> LeoBodnar, that's *way* above my pay grade :)
[17:01] <Laurenceb_> oh its 2M ?
[17:01] <Laurenceb_> i see now
[17:01] <aadamson> yeah
[17:01] <aadamson> 2mtr vertical dipole ala LeoBodnar :)
[17:01] <aadamson> was an after thought on design however so I had to jury rig it
[17:01] <aadamson> but it will work
[17:01] <arko> the US has one really big problem, size
[17:02] <arko> unless people did floaters more often
[17:02] <arko> otherwise you are gonna localize stations to cities
[17:02] <aadamson> found a really nice small 1S battery... it's less than 5grams, 200mah, and is about 8 or 9 x 30x 5 mm
[17:03] <aadamson> arko, I think *more and more* are going to do floaters or try too and that doesn't mean pico's

[17:03] <aadamson> I talked to a guy in CA last night (he called me about my design) and they are trying for round the world on a custom envelope
[17:03] <Laurenceb_> what like Leo ?
[17:03] <Laurenceb_> :P
[17:03] <Laurenceb_> im better on Leo to manage that one first
[17:04] <aadamson> Laurenceb_, oh, I should have said 100+ gram payload
[17:04] <Laurenceb_> ah
[17:04] <aadamson> so now we are talking 60K feet and round the world
[17:04] <aadamson> but I know no more than that
[17:04] <mattbrejza> 60000 ft
[17:04] <SIbot> In real units: 60000 ft = 18 km
[17:04] <arko> this is like space programs trying to start up
[17:04] <arko> they all say they are going to do it
[17:04] <aadamson> arko, yep, indeed
[17:04] <arko> but you gotta just do it
[17:05] <aadamson> what was funny was the amount of $$$ they had spent (hobby dollars mind you) for this
[17:05] <aadamson> special tooling for the envelope etc... I got the impressing the *dad* was in some form of the manufacturing business
[17:05] <aadamson> but you know, each has their definition of fun...
[17:06] <aadamson> lots of guys spend obscene amounts of money on racing various things as well - for hobby/sport whatever

[17:08] <aadamson> amazing how fast you have to be and flux helps *a little*, but can quickly get your in trouble
[17:09] <aadamson> ian__, btw ^ thanks for the comments...
[17:10] <aadamson> btw, how frequently is the data refreshed on the predict site?
[17:11] <arko> are you *serious*?
[17:11] <jonsowman> aadamson: models are published 4 times per day
[17:11] <aadamson> ok, probably same timeframe as aviation winds aloft, etc?
[17:11] <arko> noaa releases weather/wind data every 6 hours ^
[17:12] <jonsowman> i've no idea
[17:12] <aadamson> the model using data is yyyymmdd?? what are the last 2 digits?
[17:12] <jonsowman> time
[17:12] <aadamson> in the scenario information box
[17:12] <jonsowman> hour, more precisely
[17:13] <aadamson> ok, thanks
[17:14] <aadamson> jonsowman, I think from the info I know the answer, but the max prediction will be for flight time of 6hr59min?
[17:14] <aadamson> so it's 7 hours from the launch point to the green dot?
[17:15] <aadamson> nah, that can't be right
[17:15] <jonsowman> hmm?
[17:15] <jonsowman> the maximum flight time is 180 hours in theory
[17:15] <jonsowman> since that's how far into the future the model has wind data
[17:15] <aadamson> e.g - http://predict.habhub.org/#!/uuid=86a43f68d955450e7231911e8783c0e9c455b8eb
[17:16] <aadamson> assuming that link works
[17:16] <aadamson> it says 2185km range, and 6hr59 flight time

[17:16] <aadamson> but that must be the 180 hr mark, not the 7hr one
[17:16] <aadamson> that would make more sense
[17:17] <jonsowman> it may be that the server only fetches a few hours
[17:18] <craag> I think it's more that it didn't finish the prediction, so hasn't timed the float
[17:18] <craag> The timing is only for the ascent
[17:19] <aadamson> craag, ah, that makes sense...
[17:19] <craag> Although the maths doesn't work out...
[17:19] <craag> but is probably related to that
[17:20] <aadamson> yeah
[17:20] <aadamson> I forget if it was adamgreig or who, but someone mentioned that there is a new version in the works to do better with floats

[20:51] <aadamson> mikestir, what voltage are you running your arm at?
[20:51] <Lunar_Lander> thanks Anthony
[20:51] <Lunar_Lander> I can try to look over it
[20:52] <aadamson> mikestir, I know you are using a different boost controller, but I just did a back to back of the TI61200 vs the ltc3526L - HUGE Difference at STOP current
[20:53] <aadamson> the TI61200 is drawing 10mA, whereas the LTC is only 2mA when the demand is less than 1mA

[20:55] <aadamson> Upu, it's larger when you apply that to the fact that with my scheme it's a 3:1 ratio of stop to run so that equates to 4.5 days on AA on the TI vs. 6.2 days (all in theory) on the LTC

[20:56] <aadamson> yeah, going the other way buck vs boost is much better
[20:56] <Upu> never bothered to test it to that level
[20:56] <aadamson> I was just surprised at the difference at the low current mode between the 2 boost controllers

[21:36] <ian__> aadamson: forgive the queston, but have you checked that the upper part of your dipole won't desense your GPS when transmitting? You did say that you had cobbled it together, so wondered if you had fully checked out that aspect. Probably dumb question, but best asked I think!
[21:38] <aadamson> ian__, yes, I actually use a similar setup on my development board, but thanks for asking
[21:40] <aadamson> The bigger think that desensed the gps was the solar/lipo power board being too close to the gps... Not sure what does it, but for this flight I mounted it below the GPS so at least it has a ground plane or 2 between the 2. when I spin the board the whole power, pin, interface will be moved down and away

[21:45] <mikestir> I thought you meant it was literally on the back of the board under the gps - I was wondering how that constituted separation on a 2 layer
[21:45] <aadamson> ah no
[21:45] <mikestir> I haven't tested mine that extensively yet, but it will hold a fix indoors with a quarter wave wire
[21:46] <aadamson> this one will too, even where it was... inside the house 5 sats with the board up by it, 8-9 with it away
[21:46] <aadamson> mikestir, ps - https://dl.dropboxusercontent.com/u/6730484/mah%20calculator.xlsx
[21:47] <aadamson> I ran all the numbers with actual sampled data on all my various power options
[21:47] <aadamson> only number I didn't pull was the TI61200 delta when the transmitter was on, but I did on the LTC3526L
[21:48] <aadamson> top section is solar/lipo, bottom left TI61200, bottom right LTC3526
[21:48] <mikestir> I may see if I can get some power measurements done this weekend. Those numbers look fairly similar to mine, but I'm only going off the bench supply, which might not be that accurate
[21:48] <aadamson> seeing as I *was* going to launch today, but now I'm dodging thunderstorms :(
[21:49] <aadamson> they those are all sampled from the batteries on the battery side of the buck/boost
