[06:42] <DL7AD> yes i did
[06:44] <malgar> and I received the balloon PYSY from Regensburg with a SDR and a homemade yagi.. and I'm not experienced at all. Maybe it's because of his fixed station at the bottom of the valley. There are a lot of mountains around

[08:03] <LeoBodnar> it had GPS problem so kept trying to reset it
[08:03] <LeoBodnar> looks like temperature related
[08:03] <Steve_G0TDJ> Ah ha. It's a bit fady with me here at the mo. Although I'm impressed with Contestia's low signal performance
[08:04] <Steve_G0TDJ> Did B-52 really get to 46,000+M?
[08:07] <Upu> refresh
[08:08] <LeoBodnar> nunca

[08:24] <Steve_G0TDJ> I should be able to hear it once it get's up a bit

[08:25] <mikestir> same
[08:25] <Upu> I can see a carrier on 075 as well
[08:25] <Upu> however
[08:25] <daveake> ok that's it then
[08:25] <Upu> 5 mins isn't enough for it to get in range of me and Rob ?
[08:25] <jonsowman> yeah got a carrier here too (Southampton)
[08:25] <rob_m0dts_> maybe some ducting about with high temps
[08:25] <mikestir> I'm fairly sure that carrier wasn't there half an hour ago
[08:25] <daveake> wasn't there when I checked just after 8am
[08:25] <bennyboy> I checked it on my of early this morning and it was OK, but I don't have a portable receiver.
[08:25] <jonsowman> it's not very stable either
[08:26] <jonsowman> drifting up in freq
[08:26] <daveake> yup
[08:26] <Upu> crrier isn't good bennyboy as it means its not transmitting naything
[08:26] <mikestir> but at least you might be able to DF it

[08:32] <daveake> well, to be brutally honest, you just wasted your budget
[08:32] <mikestir_M0MKS> I would have spent the money that went towards the phone on an rtl dongle to use in a laptop
[08:32] <daveake> you have approx 50% chance of that backup working
[08:33] <bennyboy> and according to all the literature they are no good for anything other than a bench test. you need a real receiver
[08:34] <mikestir_M0MKS> what, an rtlsdr? it would be fine when you're 2 feet away from the payload!
[08:34] <SIbot> In real units: 2 ft = 0.61 m
[08:34] <bennyboy> if I loose it I loose it. I'm not going to cry over it.
[08:34] <jonsowman> you know for next time bennyboy :)
[08:34] <Upu> well RTL is better than nothiing
[08:34] <Upu> ok mistake made hope the GSM kicks in
[08:34] <Upu> I guess it was working at some point
[08:35] <jonsowman> it's no fun if you get it all 100% right the first time ;)
[08:35] <rob_m0dts_> that's true
[08:35] <Upu> hah
[08:35] <LeoBodnar> according to literature this channel does not exist
[08:35] <Upu> My first launch the transmitter stopped working and I landed in the sea
[08:35] <Upu> but at least I had a radio :)
[08:36] <malgar> what? I received a HAB signal from 330 km using a rtl dongle
[08:36] <Upu> s/transmitter/GPS
[08:36] <malgar> so.. 2 feet are not 330 km :P

[12:08] <Upu_M0UPU> works on mine
[12:08] <Maxell> Well, rtl-sdr here so meh
[12:09] <Upu_M0UPU> I have 2 FCD's dunno if that makes a difference
[12:09] <fsphil> the fcd comes up as an audio device
[12:09] <craag> funcube is an audio soundcard
[12:09] <craag> rtlsdr is a USB device
[12:09] <Upu_M0UPU> for the record the older FCD with a habamp >> FCD Pro+
[12:09] <fsphil> windows and linux can allow recording from the same device multiple times
[12:09] <craag> Only one program can bind to a USB endpoint
[12:10] <craag> With audio - obviously you can have many!
[12:10] <PE2G> ZURG burst
[12:10] <Maxell> craag: ah that would be it
[12:10] <fsphil> the OS connects to the endpoint once, shares the data
[12:11] <daveake> ok a bit early 33km instead of 35.5
[12:11] <craag> (The funcube control is a usb endpoint, hence why only one program can *control* it)
[12:11] <Maxell> craag: yes I know this.
[12:11] <fsphil> I wonder what would be involved in creating an audio driver for the rtlsdr
[12:11] <fsphil> probably vastly easier for linux
[12:11] <Maxell> craag: but if coded right you could open de device one, (deamon) and then stream the iq data two many sdr#s
[12:12] <fsphil> aye
[12:12] <Maxell> s/two/to/
[12:12] <mfa298> or on windows just use sdr-radio as it effectively does all that internally for you
[12:12] <fsphil> be a handy way to setup a websdr
[12:12] <craag> Maxell: Absolutely.. once you've got it out of rtl_tcp or something, it's just a data stream
[12:12] <fsphil> just a process to read IQ data
[12:12] <fsphil> and sub-processes to do demodulation
[12:13] <fsphil> make good use of a multi-core processor
[12:13] <craag> ^^ Exactly how websdr works
[12:13] <craag> ok, not the last bit
[12:13] <fsphil> completely separate processes?
[12:13] <craag> (It's all scheduled on a single thread
[12:13] <fsphil> that's the flaw
[12:13] <craag> mm don't I know it!
[12:14] <mikestir_M0MKS> that's how webradio works (demods on their own threads), if only I had time to finish it
[12:14] <fsphil> no reason it couldn't be done with multiple proceses and some shared memory
[12:14] <fsphil> the advantage being you could have multiple sources too
[12:14] <craag> Well currently what's holding us back is a hardcoded limit to 4x rtlsdr devices...
[12:14] <fsphil> or have them on separate machines
[12:15] <Maxell> craag: yep once you have the iq stream there is no limit. Well, cpu power would be the limit :P

[18:27] <Lunar_Lander> many of the new viewers here might not know it, but Dave actually flew the first piece of my balloon project in 2012 (do I have this right?), it was a mission patch I designed
[18:27] <Lunar_Lander> and the balloon landed off the southern coast of england, but drifted on the beach with the rising tide about an hour later
[18:27] <Lunar_Lander> :)

EDBG also supports a virtual COM port that can be used for device programming and traditional Arduino boot loader functionality."

[19:32] <mikestir> for full bluetooth serial you need an auth chip, and you can only get that if you're a member of apple MFI

[21:56] <SpeedEvil> It's a damn shame that this sort of stuff hasn't been tested.
[21:56] <amell> They did it with Viking in 1972
[21:56] <Lunar_Lander> yea I recall reading this
[21:56] <Lunar_Lander> I think the later landers were also drop tested

[21:59] <Lunar_Lander> thanks Upu
[21:59] <Lunar_Lander> that was awesome

[22:03] <Lunar_Lander> I have the movie here
[22:03] <Lunar_Lander> recorded off TV years ago
[22:03] <Lunar_Lander> never had the time to watch it
[22:03] <Lunar_Lander> same with the box set of "Cosmos" :(
[22:03] <toxygen> :)
[22:03] <Lunar_Lander> I have to
[22:03] <Lunar_Lander> Carl Sagan was awesome
[22:03] <toxygen> i watched the movie few months ago, after many many years since first watching
[22:03] Willdude123 (~Willdude1@unaffiliated/willdude123) joined #highaltitude.
[22:03] <fsphil> I could listen to carl sagan read a phone book
[22:03] <toxygen> anybody here watching the new cosmos series?
[22:03] <fsphil> he's got a great speaking voice
[22:04] <Lunar_Lander> yeah
[22:04] <Lunar_Lander> I only know about the new series from people who can watch it on Pay-TV here in Germany
[22:04] <daveake> If he did (and yes that's a tad tricky) I'd change my name to "Pale Blut Dot"
[22:05] <Lunar_Lander> one said that he didn't like that Tyson didn't get to a point in episode 10 about electricity
[22:05] <fsphil> Mr.Dot, inventer of the Matrix
[22:06] <Lunar_Lander> he said he was disappointed when Tyson said "Don't worry if you do not understand it. Science took more than a century for that"
[22:07] <fsphil> Jim Al-Khalili sometimes puts a few equations in his shows
[22:07] <fsphil> it's a bit more sciency
[22:08] <Lunar_Lander> he had a nice three part show on chemistry that was shown on arte in Germany
[22:08] <fsphil> he's done a fair few interesting programs
[22:08] <Lunar_Lander> starting from the discovery of Phosphorus by an Alchemist and then Robert Boyle having been the first real chemist and the strange idea of phlogistonium
[22:08] <Lunar_Lander> yea
[22:08] <SpeedEvil> amell: they diddn't - the stuff they're doing with the inflated parachutes is quite different in principle. And leads on to supersonic lifting parachutes - which may be required to cheaply land large volumes on maes.
[22:08] <Lunar_Lander> and Lavoisier clearing that up
[22:09] <amell> I bow before your superior knowledge

[22:14] <SpeedEvil> I'm thinking of building a general purpose thingy
[22:15] <SpeedEvil> Which I can put a milling, router, drill, printer head on

[22:18] <amell> speed vs torque.
[22:18] <SpeedEvil> amell: yes - you have to fundamentally work out stiffness and repeatability.
[22:20] <amell> I wouldnt want milling swarfe near my 3d printer.

[22:26] <N2NXZ> Short notice,but pointing 6 element yagi in general direction at this time.
[22:28] <fsphil> oh was bill flying today
[22:28] <fsphil> missed that

[23:46] <N2NXZ> Anything from the WB8ELK balloons yet? I really have little information regarding the flight plans.Setup to listen if they are going long...otherwise,going to pull the plug.here.
[23:52] <N2NXZ> Testing 1,2,3 testing :)
[23:53] <craag> N2NXZ: Working fine - but no-one knows about WB8ELK
[23:53] <N2NXZ> Strange...maybe they are testing trackers rather than launching
[23:54] <N2NXZ> Thanks for the info,going to shut down.
