[07:04] <KT5TK> Sorry, I was afk, soldering a bunch of 915 MHz preamps
[07:05] <arko> nice
[07:05] <arko> i'm getting some terrible frequency drift on this chip
[07:06] <KT5TK> Darkside: I added a color sensor because I wanted a day/night sensor. While I needed just a photodiode I thought RGB was more flexible
[07:06] <KT5TK> arko: What oscillator are you using?
[07:06] <arko> 30Mhz external
[07:07] <KT5TK> Are you sure that you connected it to the Xout pin of the Si4464?
[07:07] <KT5TK> NOT Xin pin
[07:08] <arko> hmm
[07:08] <arko> i dont follow
[07:08] <arko> one pin of the crystal is on xin
[07:09] <arko> and the other pin is on xout
[07:09] <KT5TK> It's misleading in the datasheet
[07:09] <arko> oh?
[07:09] <KT5TK> For some reason you must insert your oscillator signal to the Xout pin
[07:10] <arko> are you sure?
[07:10] <KT5TK> if the internal oscillator is off, then the Xin pin is disconnected.
[07:10] <arko> its booting and transmitting at the correct freq
[07:10] <KT5TK> Yes, this took me several weeks to find out
[07:10] <arko> so where does the other leg for the crystal go?
[07:10] <KT5TK> it's probably swinging free
[07:11] lz1dev (~rgp@188-221-236-112.zone12.bethere.co.uk) joined #highaltitude.
[07:11] <KT5TK> the Xin is floating
[07:11] <arko> yeah, its very slowly drifting
[07:11] <KT5TK> Do you want to do FM or rtty with it?
[07:11] <arko> rtty
[07:12] <arko> its mostly working
[07:12] <KT5TK> ah, then you probably need a TCXO
[07:12] <UpuWork> morning all

[07:14] <arko> frequency is drifting
[07:14] <arko> :)
[07:15] <UpuWork> does yours have a TXCO on it ?
[07:15] <KT5TK> I have tried rtty also, but it was drifting a lot as well. Therefore I have now a GPIO pin connected to the ATMega and I'll try to let the Si4464 generate the FSK

[07:16] <arko> i kaynar wired a pin

[07:18] <arko> KT5TK so a crystal like in the datasheet is wrong?
[07:18] <KT5TK> The Si4464 is primarily made for FM modes. I mainly do AFSK1200. But it should be possible to generate clean rtty with a TCXO
[07:18] <arko> that seems wrong that its wrong :P

[08:09] <G0TDJ_Steve> Whats B8's target altitude LeoBodnar?
[08:09] <fsphil> I have a K8055 in the attic somewhere
[08:10] <fsphil> I can update the info box shortly if someone else hasn't already
[08:10] <gonzo__> actually, the k8055 was originally used on our DV repeater with your SW. retired it when it went over to a hardware modem board
[08:10] <gonzo__> will have a listen for B8, but there is a lot of loss in the system now
[08:15] <Jonathan_G4KLX> gonzo__: I know, I wrote the DV software!
[08:17] <chrisstubbs> G0TDJ_Steve: I think becuase the ublox was in power save mode, the 808 interfered and when the ublox lost fix. it reset itself
[08:17] <chrisstubbs> and came out of flight mode
[08:17] <chrisstubbs> the code now just sticks it in flight mode once a second. Might be flying it again this evening!

[08:20] <chrisstubbs> fsphil: I figured you cant really do it too much, i was thinking about querying the mode and changing it if not right. however you may as well drop the check command and just set it
[08:21] <fsphil> I was paranoid about the command to change mode affecting the position somehow
[08:21] <fsphil> though if it's setting a mode it's already in, I doubt it would

[09:22] <Lunar_LanderU> ed recently discussed with me using a bipolar NPN transistor for inducing the reset on the electrometer, and I just found this http://electronics.stackexchange.com/questions/23190/why-do-you-need-2-resistors-when-hooking-up-a-transistor-as-a-switch
[09:23] <Lunar_LanderU> my question would indeed be, do you need R2?
[09:24] <Lunar_LanderU> if I read that correctly, R2 helps to shut the transistor off
[09:24] <Lunar_LanderU> if there is a LOW signal on B
[09:24] <Lunar_LanderU> but do you need that?
[09:26] <fsphil> if you don't and your IO pin is floating, the transistor may switch on
[09:26] <Lunar_LanderU> which is bad
[09:26] <Lunar_LanderU> so better include it
[09:26] <daveake> Yes
[09:26] <fsphil> the pin may float for a moment after the microcontroller switches on
[09:26] <Lunar_LanderU> also ed recommended 100k, my prof said 1k is well enough
[09:26] heathkid (~heathkid@unaffiliated/heathkid) joined #highaltitude.
[09:26] <Lunar_LanderU> yea
[09:27] <fsphil> 100k is fine
[09:27] <daveake> In practice it'll probably be just fine without it, but it's worth adding
[09:27] <Lunar_LanderU> ok
[09:27] <LeoBodnar> If your circuit might end up with high impedance on R1 like when MCU comes out of reset you may want R2 as protection against transistor tuning on from spurious signals.
[09:27] <Jonathan_G4KLX> I'd also include a decoupling capacitor from the base to ground, especially in the presence of RF.
[09:27] <Lunar_LanderU> yea
[09:28] <Lunar_LanderU> ah ok, hanks
[09:28] <Lunar_LanderU> +t
[09:28] <Lunar_LanderU> I suppose 100k is also a good value for R2?
[09:28] <Lunar_LanderU> or 10k-100k
[09:28] <Lunar_LanderU> in that range
[09:28] <LeoBodnar> If it is driven with low impedance driver like CMOS output then you might as well omit it.
[09:29] <LeoBodnar> Yes, should be OK.

[09:48] <BRS38937> Hi
[09:48] <ibanezmatt13> Hi Willdude123
[09:48] <ibanezmatt13> daveake: on the Pi N Chips board, how is the digital temperature sensor connected to the Pi? I2c?
[09:49] <daveake> It's a DS18B20
[09:49] <daveake> Which isnt i2c
[09:49] <daveake> It's "One Wire" (though "one" is "three" really)
[09:50] <daveake> Google for that chip and "raspberry pi" there's plenty of info
[09:50] <ibanezmatt13> I see. Will do that now. Thanks daveake
[09:52] <fsphil> I like 1-wire. it's easier than i2c
[09:52] <Laurenceb> LeoBodnar: whats the free lift on B8?
[09:52] <ibanezmatt13> daveake: on the Pi n chips board, is the data pin for the DS18B20 connected to pin 7 on the GPIO? (GPIO 4 I think) ?
[09:54] <daveake> Have a look at the diagram
[09:54] <Laurenceb> looks about 1m/s ascent, so higher than previous
[09:54] <daveake> It's supposed to be GPI4 because that's what Raspbian expects
[09:54] <daveake> GPIO4
[09:54] Action: Laurenceb guesses 2 grams
[09:54] <Laurenceb> be interesting to see if it floats ok
[09:55] <Laurenceb> is there a prediction for this?
[09:57] <LeoBodnar> Laurenceb: 1.3 grams
[09:58] <LeoBodnar> Higher ascent rate due to sunshine heating. I used to launch during evenings before.

[10:02] <Jonathan_G4KLX> It's sending a short carrier every second or so most of the time.
[10:02] <chrisg7ogx> nothing here
[10:03] <Jonathan_G4KLX> Where are you?
[10:03] <mfa298_> I think I need to setup a special config directory for Leo's flights and put the radio frequency into a memory. It's that stable (even between flights) :D
[10:06] <BRS38937> B* is on 434.5003 be patient set radio to USB it only beacons evry 5 mins or so listen for bleeps and look for bars on your screen set auto config, its not strong on the south coast I can hear it but not got a green out of it y et

[10:10] <mfa298_> I've wondered whether it would help if the beacons started at set times. Might make finding it easier when you don't have it.
[10:10] <mattbrejza> tbh its meeting the nyquist sampling criteria, no need to send any more data
[10:10] <Jonathan_G4KLX> LeoBodnar: Am I right in saying that you send a short carrier every second or so, and then about ten seconds before the beacon you miss one out, and then just before the beacon you send a double "blip"?
[10:10] <chrisg7ogx> That's what threw me then and also not having the antenna plugged in!
[10:11] <Laurenceb> no sign of float
[10:13] vladimirek (~vladimire@ joined #highaltitude.

[10:14] <Geoff-G8DHE-M> OK I
[10:14] <Geoff-G8DHE-M> ll assume the last one was the last received time
[10:15] <LeoBodnar> Jonathan_G4KLX: I don't have multitasking inside this one so it pauses to collect data from GPS. And because you can hit GPS at any time inside its internal update cycle it will take any time to return data from 0 to 5 seconds. THis will sound like a missing beep or extended pause.
[10:15] <LeoBodnar> It's not very tidy on the air but simple to implement.
[10:16] <Geoff-G8DHE-M> About 1 miute ?
[10:16] <Jonathan_G4KLX> LeoBodnar: It's also good because it gives you warning of an impending beacon if you've got the PC unplugged.
[10:16] <BRS38937> Does it really matter? - its more of a challage for us, and keeps it simple
[10:16] <LeoBodnar> Yes, double blip is just before DominoEx burst
[10:17] <Geoff-G8DHE-M> Got it
[10:17] <Geoff-G8DHE-M> At least to tune to!

[10:19] <UpuWork> FCD Pro+ is way more sensitive
[10:19] <LeoBodnar> I can't put MAX-6 to sleep! It just keeps waking up - little restless rascal.

[10:20] <LeoBodnar> I miss Bettys shops
[10:20] <G0TDJ_Steve> LeoBodnar: Can't you literally power down the MAX-6 or does it take too long to acquire sats?
[10:21] <LeoBodnar> I'll go radical next time - MOSFET to cut the power (leave VBATT on)
[10:21] <BRS38937> just beaconed
[10:21] <Geoff-G8DHE-M> Partial decode, dongle still warming up!
[10:21] <UpuWork> uses power better to link battery to vbatt and just turn it off
[10:21] <UpuWork> the circuit works I use it on mine
[10:21] <LeoBodnar> It amazes me why one has to - it's not 1980's
[10:21] <mattbrejza> low power mode not enough then?
[10:22] <LeoBodnar> No, 10mA+ current all the time
[10:22] <mattbrejza> it is still tracking though, but i thought there was a deeper power state
[10:23] <LeoBodnar> UBLOX-6 protocol spec: "On firmware 7.03, on/off operation is not available." What this is all about?! :-/
[10:23] <UpuWork> http://i.imgur.com/fmzDRts.png

[10:32] <mattbrejza> are you sure you cant put it to sleep, im fairly sure thats what kraken does
[10:33] <LeoBodnar> Maybe through some jumping through hoops but life is too short mattbrejza :) Just when you think it's down it comes back for no reason and demands 40-50mA

[10:50] <LazyL_M0LEP> The knee is where the balloon gets taut, and then there's still some rising to do but it's not assisted by the balloon expanding so much, though it'll be stretching a little one way or another.
[10:50] <LazyL_M0LEP> ...or so i figure...
[10:51] <LeoBodnar> That's when envelope starts stretching elastically first and then plastically.
[10:52] <LeoBodnar> If you were to take it down and launch again the knee will be higher because the envelope is irreversibly stretched and the volume is higher
[10:52] <LazyL_M0LEP> Right.
[10:53] <LeoBodnar> You get more balloon for your money thanks to the Sun :)
[10:53] <LazyL_M0LEP> Wasn't sure how much of the stretch was plastic.
[10:53] <LazyL_M0LEP> ;)
[10:54] <LeoBodnar> http://leobodnar.com/balloons/B-6/1.png the difference between 1st night float and 2nd night float is due to envelope unable to contract to original size

[11:10] <HixWork> how do you get this HYSPLIT data?
[11:10] <SpeedEvil> My recommended procedure is: Wash your hands. Now, with some clean 600 grit sandpaper, clean the attachment point to brightness. Immediately add a tiny smear of flux. Now, with a hot iron, with the flat placed horizontally - place a blob of solder on the iron, and touch the battery to it for half a second or so.
[11:10] <G0TDJ_Steve> Some trip chrisstubbsW
[11:10] <chrisstubbsW> select isobarix HixWork
[11:10] <chrisstubbsW> *isobaric
[11:10] <SpeedEvil> You should be able to immediately touch the battery afterwards without pain - it cools so fast.
[11:11] <HixWork> sounds like my brother chrisstubbsW
[11:11] <cyclops> I bought "Eco Flux"
[11:11] <SpeedEvil> Leave it to fully cool, and then place a tinned wire against the solder, and repeat the process
[11:11] <cyclops> And it says it has to ble cleaned
[11:11] <chrisstubbsW> XD

[11:30] <fsphil> I've removed the test positions from spacenear
[11:30] <fsphil> altitude graph is very steppy
[11:31] <G0TDJ_Steve> Cheers fsphil That's a lot tidier
[11:33] <ibanezmatt13> On this guide http://ukhas.org.uk/guides:ublox6 what is the difference between myserial and Serial?
[11:33] <ibanezmatt13> I'm looking at the hardware serial section
[11:34] <HixWork> myserial is software serial
[11:35] <HixWork> which is ok for testing but not for flight
[11:35] <ibanezmatt13> I'm not sure what the software serial is being used for.
[11:35] <Piet0r> Is used for debug information
[11:35] <Piet0r> So you can monitor on your PC what the unit is doing
[11:36] <ibanezmatt13> So is myserial the serial connection through the USB cable to the serial monitor on the PC?
[11:36] <Piet0r> Indeed
[11:36] <HixWork> yes
[11:36] <Piet0r> The hardware serial is connected to the GPS unit
[11:36] <ibanezmatt13> So what's the actual serial then for the Ublox? I thought just doing Serial. would talk to the PC to
[11:37] <Piet0r> The hardware serial does all operations in a dedicated UART-chip
[11:37] <Piet0r> So the CPU does not have to do that
[11:37] <Piet0r> When using software serial the CPU is doing all the stuff
[11:38] <Piet0r> So you have less CPU-cycles to do actual work
[11:38] <chrisstubbsW> LeoBodnar: thats the plan
[11:38] <chrisstubbsW> cheapo 6
[11:38] <ibanezmatt13> Ah I see. So where it says Softwareserial myserial (4, 5) the 4 and 5 are the pins connected to the FTDI module that is connected to the PC?
[11:38] <HixWork> yup
[11:38] <Piet0r> Yes
[11:39] <ibanezmatt13> That makes sense then, thanks. I was getting confused with the connections
[11:39] <ibanezmatt13> I was thinking that pins 4 and 5 were tx and rx :)
[11:40] <Piet0r> They are, but they are tx/rx to your PC
[11:40] <Piet0r> 1 and 2 are tx/rx to your GPS receiver
[11:40] <ibanezmatt13> I see. I understand that now

[12:27] <Laurenceb> very clever
[12:28] <mattbrejza> that will probably upset spacenear, but probably isnt causing any issues atm as the archieved data it's sent has already been recieved and plotted

[12:55] <mattbrejza> orginal launch date for this one was july but lets ignore that

[14:27] <LazyL_M0LEP> Electric fences are a right nuisance. Noise blanker will usually take out one, but if there are half a dozen then most of them get through.
[14:28] <LazyL_M0LEP> However, this problem's a high-revs petrol strimmer.
[14:28] <LazyL_M0LEP> I can see the QRM going up and down with the revs...
[14:29] <LazyL_M0LEP> ...and B-8 is pretty much out of range now anyway.

[16:08] <Jonathan_G4KLX> -14 dB here, I assume it's -14 dB in the noise bandwidth of dl-fldigi which appears to be 2700 Hz.

[16:09] <cm13g09> it doesn't seem to line up with the bars in dl-fldigi

[16:21] <mfa298_> I've found mine aren't too bad. It's good enough to find the signal the tuning is just slightly off from where it should be.
[16:21] <cm13g09> that's why I want to use chrisstubbs' launch
[16:21] <cm13g09> in order to test
[16:22] <Lambeta> KT5TK, I came across your pecan pico 3 project using the SI4463/64
[16:22] <HixWork> a tracker will really pin it down
[16:22] <chrisstubbs> cm13g09, its transmitting now, want me to throw it on the roof?
[16:22] <mfa298_> I found trying to work on the correction using APRS failed miserably as everyone's TX seemed to be slightly off.
[16:22] <Lambeta> I switched a month ago from using the CC1125 SoC from TI to the SI4464 because it's much friendlier towards AX.25
[16:22] <cm13g09> lol
[16:22] <chrisstubbs> you might get it from the other side of town haha
[16:22] <cm13g09> can try it ;)

[16:23] <KT5TK> I actually just built a Pecan 4
[16:23] <Lambeta> Using the same ic?
[16:23] <cm13g09> chrisstubbs: is you have a way to launch the signal skywards
[16:23] <KT5TK> and it worked right out of the box
[16:23] <cm13g09> *if
[16:23] <Lambeta> how did you modulate the data? using the built in vco/modulator/mixer
[16:23] <chrisstubbs> ok will do. It took 15 mins to get a fix with the new software :/
[16:23] <Lambeta> or did you provide a modulated data stream to the ic?
[16:24] <chrisstubbs> sill be better for flight mode but may delay the launch a little.
[16:24] <KT5TK> yes. See https://kt5tk.wordpress.com/2013/07/24/pecan-pico-4-serial-number-1-built-working/
[16:24] <cm13g09> fair enough
[16:24] <KT5TK> I actually modulate the VCXO
[16:25] <Lambeta> and you just send data to it?
[16:25] <Lambeta> bit bang?
[16:25] <KT5TK> The transmitter is just switched on and off
[16:26] <Lambeta> the documentation is not that great when it comes to using the built in fifo
[16:26] <Lambeta> i'd like to send data to the fifo and have the si4464 fsk modulate it
[16:26] <KT5TK> the AFSK is generated by the micro
[16:26] <Lambeta> I'm looking at using MSK
[16:27] <Lambeta> but there seems to be nothing in regards to greater than fifo length
[16:27] <KT5TK> The Si4464 can do 4FSK only in internal mode
[16:27] <cm13g09> chrisstubbs: I'm seeing nothing :(
[16:27] <Lambeta> right - using the fifo

[17:51] <G0TDJ_Steve> Wacky prediction chrisstubbs
[17:51] <PE2G> Hi all, just to be sure: is B-8 sending beeps between data strings?
[17:51] <LeoBodnar> Yes
[17:51] <Jonathan_G4KLX> LeoBodnar: Is the GPS locking for the TX on your trackers done via the CPU or just in hardware?
[17:51] <PE2G> Then I think I'm receiving it!
[17:52] <fsphil> my pico repellent field is working well
[17:52] <LeoBodnar> CPU, GPS can only output 1kHz ref signal and PLLing TX to it in HW would be night on impossible
[17:53] <PE2G> Green decodes! Dx 481 km elev -1.3 deg
[17:53] <fsphil> sweet
[17:53] <LeoBodnar> AD makes some chips that can take 50kHz reference signal but they are big and hungry
[17:53] <fsphil> there might actually be a chance I could receive this
[17:53] <LeoBodnar> Haha well done PE2G
[17:53] <Jonathan_G4KLX> Interesting, Andy Talbot has done a lot of work using the 1pps output of a GPS with good results. All in hardware though.
[17:54] <PE2G> Very excited about this, I am so far outside the bleu circle
[17:54] <fsphil> sporadic e :)
[17:54] <LeoBodnar> Yes, but he probably uses slow LPF before PLL?
[17:54] <Jonathan_G4KLX> PE2G: Nice over sea ducting I'd imagine.
[17:54] <Jonathan_G4KLX> I think so.
[17:55] <PE2G> The beeps are getting even stronger :)
[17:55] <Jonathan_G4KLX> http://www.g4jnt.com/freqlock.htm
[17:56] <LeoBodnar> I wanted more agile correction when needed. E.g. when GPS is powered down you have no reference so when you wake up you need to correct quickly and decisively
[17:57] <LeoBodnar> MAX-7 can output up to 1MHz reference signal. It is very short stretch from there to just feeding it directly to the UHF synth.
[17:57] <Jonathan_G4KLX> The system you use would be worthy of publication.
[17:58] <fsphil> no sign of it here
[17:58] <LeoBodnar> Si4460 might even accept 1MHz reference input, who knows I can't see a reason why not.
[17:58] Hiena (~boreger@ joined #highaltitude.
[17:58] <LeoBodnar> But phase noise on GPS output reference signal might be horrible.
[17:58] <fsphil> is the dial freq. 434.500 UAB?
[17:58] <fsphil> USB*
[17:59] <Jonathan_G4KLX> It usually is, people using it to lock uwave oscillators notice that more than most.
[18:00] <mfa298_> LeoBodnar: reading back a bit, For international waters I think HAM usage is based on UK regs (or your licenced country) and the ITU region - So no HAM usage for a UK license. Over other countries it's down to CEPT and the visited countries regs.
[18:00] <LeoBodnar> AD makes very nice chips for reference pulse train locking and they clean up the phase noise by employing intermediate crystal oscillator, but they are not really for portable use so I did not investigate.
[18:01] <LeoBodnar> They are used in mobile network base stations
[18:02] <LeoBodnar> What laws/regulations are governing RF transmission in international waters?
[18:03] <arko> "go crazy!"
[18:03] <PE2G> fsphil: 434.45013 , cursor freq 1278 Hz here

[18:11] <arko> but i have some drift, did you use a TCXO?
[18:11] <fsphil> not a trace of it
[18:11] <arko> or 30mhz crystal?
[18:11] <arko> some terrible squiggles
[18:11] <fsphil> PE2G: impressive. you can't even see the signal
[18:12] <PE2G> Antenna direction is very critical, just a few deg off and the signal is completely gone
[18:12] <arko> LeoBodnar: if the fsk devation is 1k it drifts, but at like 500k it's nice and stable :/
[18:12] <fsphil> I'm on a colinear which probably explains it
[18:12] <LeoBodnar> yes arko
[18:13] <arko> yes to tcxo?
[18:13] <LeoBodnar> Is your crystal near the TX chip?
[18:13] <arko> yeah
[18:13] <arko> right next to it
[18:14] <LeoBodnar> It hits it up! Place it as far as possible despite what common sense says
[18:14] <LeoBodnar> yes, TCXO but used crystal as well
[18:15] <arko> http://i.imgur.com/SU5sP9Y.jpg

[18:16] <PE2G> fsphil: I can see the beeps and the telemetry in dl-fldigi's waterfall clearly. It wasn't in my screenshot

[18:20] <LeoBodnar> -21dB S/N oO
[18:21] <LeoBodnar> arko: Hmm, not sure about wiggles, have you tried increasing internal capacitors load? Is power supply stable?
[18:22] <arko> i have the 3.3v line directly from a clean power supply. But i will add more decouple caps, maybe it cant provide the instant current
[18:22] <arko> im bypassing my voltage reg for now
[18:23] <LeoBodnar> Wires = inductance/resistance?
[18:24] <arko> i dont follow
[18:24] <arko> also increasing internal cap load?
[18:24] <PE2G> I lost it, no trace anymore
[18:24] <LeoBodnar> Try minimum TX power to start from to avoid heat/power pull issues and then step it up when you get it working well

[18:44] <G0TDJ_Steve> Look at tit this way cyclops, It's not golf!
[18:44] <arko> this is why i've moved over to picos

[19:01] <cm13g09> craag: having fun though?
[19:01] <Lunar_Lander> seems we won't fly on the balloon in berlin
[19:02] <mclane> Lunar_Lander: launch planned? when?
[19:02] <craag> Carefully deconstructed and soldered wires to a ex-USB 12V -> 5V smpsu, then proceeded to connect it the wrong way across a 12V sla..
[19:03] <Lunar_Lander> mclane, we were invited to fly our electrometer on the PTB balloon from Lindenberg on August 6 or 7
[19:03] <cyclops> PE"G no
[19:03] <Lunar_Lander> but we won't be ready until then due to problems with getting the system running
[19:03] <craag> cm13g09: Absolutely. Lots of fun stuff coming up, just gotta get 2x working systems built by friday.. with parts arriving tomorrow.
[19:03] <mclane> ah - is the electrometer already running?
[19:03] <cyclops> Not yet PE2G

[19:04] <Lunar_Lander> mclane, not yet, the opamps seem to go into the limit all the time, and currently there seems to be a short
[19:04] <Lunar_Lander> we have to figure out why
[19:04] <LeoBodnar> craag: at least you are still alive
[19:04] <LeoBodnar> craag: ?
[19:04] <Lunar_Lander> one difficulty is that touching the protoboard on two places already changes the output
[19:05] <mclane> yea, but that's the problem with any kind of high impedance circuit
[19:05] <craag> LeoBodnar: I am today, having just got back from work. How alive I'll be on friday evening is another matter..
[19:05] <PE2G> cyclops: If you can settle for a used meteorlogical parachute, I can send you one of these:
[19:05] <PE2G> http://www.aeromet.de/products/parachutes/tech__spez__parachutes/tech__spez__parachutes.shtml
[19:05] <craag> Anyway, another reliable float from you I see Leo!
[19:06] <cyclops> the 110 or the 055?
[19:06] <PE2G> Whichever you want
[19:06] <jcoxon> LeoBodnar, what sort of flight time are we expecting?
[19:07] <jcoxon> not going to be as easy as B-6 to track
[19:07] <cyclops> price?
[19:07] <LeoBodnar> Lunar_Lander: Solution: clearly mark the places that change the values with placards "DO NOT TOUCH HERE"
[19:07] <Lunar_Lander> xD
[19:07] <PE2G> cyclops: zero euro :)
[19:07] <Lunar_Lander> I mean it like that
[19:08] <Lunar_Lander> you can place your fingers on any place on the board and the output will change
[19:08] <LeoBodnar> 4-5 days jcoxon

[19:17] <cyclops> One thing a "radar deflector" or something like that is necessary to use?
[19:18] <fsphil> it depends on local regulations
[19:18] <PaulCDR> Upu, are you about?
[19:18] <fsphil> it's not required in the UK, but I believe it is in some countries
[19:18] <cyclops> The fact is that in spain there is no regulation about balloons

[19:43] <Laurenceb__> yeah
[19:43] <Laurenceb__> i used some really basic octave code to do the sat rx

[19:43] <Lambeta> okay
[19:43] <Laurenceb__> then gnu octave to grab the sat trace
[19:43] <Lambeta> and you sampled the data how often?
[19:43] <Laurenceb__> got some doppler curves like that
[19:44] <Laurenceb__> erm - its like 2Msps or something

[19:44] <Lambeta> okay
[19:44] <Laurenceb__> i got bored at that point :P
[19:44] <Lambeta> and how long did you sample for?
[19:44] <Laurenceb__> doppler inversion is hard

[20:16] <LeoBodnar> Interesting that the B-8 internal temperature is dropping even with descent. Is it in a pocket of cold air that is sucking it down?
[20:16] <chrisstubbs> Steve_2E0VET, how are you powering the ublox. they are sensitve to psu noise
[20:17] <mfa298_> Steve_2E0VET: is that the ublox working with an arduino or just plugged into a PC.
[20:17] <Steve_2E0VET> argh... i have a question. i took the coordinates the gps pumped out and put them into google earth (or some mapping software) and it said I was in Sheffield, however i was about 20 miles away as the crow flies. any ideas?

[20:18] <Steve_2E0VET> Randomskk, it wasnt actually google earth, that was an example because I couldnt remember which one it was
[20:18] <Randomskk> give the gps a bit of time and check you have the format right
[20:18] <mfa298_> also make sure you're tellling the mapping which side of the meridian you are.
[20:18] <Steve_2E0VET> ok, lets approach this from a different angle, can you recommend a site for me to put the coordinates into

[23:01] <fsphil> wind power (not too daft, except for floaters)
[23:02] <M6PFX-1> fsphil: hmm i wanted to try out the example on the site so purchased a module but using the simple blinking LED test its not transmitting a tone. i will keep looking at what i've done wrong
[23:03] <fsphil> M6PFX-1: the ntx2 should always transmit a tone if it's powered up, and the EN pin is raised (wired to the ntx2's vcc)
[23:03] <fsphil> well not a tone, a carrier
[23:03] <daveake> this ^^

[23:03] <daveake> It's useful first test before messing about sending signals to it
[23:04] <fsphil> what receiver do you have?
[23:05] <M6PFX-1> i am using my ft857d
[23:05] <fsphil> nice radio
[23:05] <fsphil> in USB mode?
[23:05] <M6PFX-1> yep
[23:05] <G0TDJ_Steve> Seconded
[23:05] <M6PFX-1> i was tracking chris' balloon today fine, i got the module which is 434.650 from hab supplies
[23:06] <fsphil> only other comment I have is to tune around a bit. you only have 2.8khz of bandwidth, and the signal probably won't be on exactly 434.650
[23:06] <fsphil> it'll be +/- that by about 10khz
[23:06] <M6PFX-1> so to just get a carrier, i need to put + to VCC and EN, and the V0 to ground
[23:07] <fsphil> yep yep
[23:07] <M6PFX-1> and 3,3v is ok direct
[23:07] <fsphil> that'll cause it to transmit it's lowest frequency
[23:07] <fsphil> yes
[23:07] <M6PFX-1> ok
[23:07] <fsphil> 3.3v is its minimum
[23:08] <fsphil> regulates it to 3v internally I think
[23:08] <daveake> 2.8 IIRC
[23:08] <fsphil> yes that's right
[23:10] DL7AD_QRL (42f96424@gateway/web/freenode/ip. left irc: Quit: Page closed
[23:13] <M6PFX-1> right i got a tone
[23:13] <M6PFX-1> sweet atleast i know it works
[23:13] <M6PFX-1> thank you fsphil
[23:14] <gonzo__> name that tune

[23:18] LazyLeopard (~irc-clien@chocky.demon.co.uk) left irc: Quit: Now QRT
[23:18] <cyclops> One question, its advised the use of a buzzer to locate the payload?
[23:20] <daveake> I don't bother
[23:20] <cyclops> why?
[23:21] chris_99 (~chris_99@unaffiliated/chris-99/x-3062929) left irc: Quit: Leaving
[23:21] <G0TDJ_Steve> I'd like mine to send out a Morse ident
[23:21] <mattbrejza> craag: no hurry, im probably not gonna do anything with it for a week or so anyway
[23:21] <daveake> Because buzzer tones are too high in pitch to get a direction on
[23:21] <cyclops> The fact is that I dont have a handheld radio, so if I have to search for the payload in the middle of a olive tree forest I have to carri the macbook
[23:21] <cyclops> *carry
[23:21] <daveake> Make it click or something
[23:22] <cyclops> Click?
[23:22] <daveake> Right, in that case my strong advice is to buy such a radio
[23:22] <cyclops> No money
[23:22] <cyclops> :/
[23:22] <daveake> Wrong hobby then
[23:22] <G0TDJ_Steve> daveake: Would one of those BaoFengs be any good. I know it's only FM but you'd get a carrier
[23:22] <daveake> Seriously, you can buy a receiver for £100 on ebay, use it, then sell it for the same
[23:23] <daveake> Actually I've made a profit on all the ones I've sold
[23:23] <cyclops> Can you link anyone?
[23:23] <craag> mattbrejza: Ok, I'll have a go at it over the weekend.
[23:23] <craag> gn all

[23:24] cardre (~cary@cdhm1.everynet.com.au) left irc: Ping timeout: 260 seconds
[23:28] <gonzo__> just about any hoddy is the wrong one, without money. With a few exeptions
[23:28] <gonzo__> but they make you blind
[23:28] <M6PFX> so it wasn't working for me before due to the 4.7k resistor being connected between TXD and GND. i remove that and it transmits. i had it setup identically to the guide on the site. hmm
[23:28] <cyclops> and which type of radio is advised for a handheld?
[23:28] <cyclops> To search for one
[23:28] <gonzo__> any that will do SSB
[23:29] <gonzo__> if you are really cash strapped, the RTL dongle and habamp. (Think that was prob suggested?)
[23:30] <cyclops> Well I allready have the funcube dongle
[23:30] <cyclops> So that might work?
[23:30] <fsphil> M6PFX: a resistor between txd and gnd won't have any effect, if that's the only thing added to the basic circuit
[23:30] <gonzo__> you don't need to take the laptop into forrests etc. Only get near enough to get some telemerty
[23:30] <fsphil> TXD is internally pulled down by a 100k resistor
[23:30] <cyclops> What do you suggest then
[23:31] <cyclops> Well the forest are of olive trees, so 2-3 meters high
[23:31] <M6PFX> sorry it was the one between TXD and +
[23:31] <fsphil> M6PFX: okie. that will change its output frequency
[23:31] <fsphil> you probably just shifted outside your radios bandpass
[23:31] <gonzo__> ah, cyclops you have most of what you need. For final DFing, an FM handheld/scanner would work. You just listen for the quietest signal (rather than the rush of static when there is no signal there0
[23:31] <fsphil> and would need to retune higher
[23:32] <M6PFX> ok
[23:32] <fsphil> for doing rtty, we use very tiny voltage changes
[23:32] <cyclops> FM handheld radio?
[23:33] <cyclops> The fack is that ive allready spent nearly 800¬ so little money left :P
[23:33] <gonzo__> cyclops, even the cheapest scanner would work for that. as long as it covres the 434 band. Actually, you don't want one that is too sensitive.
[23:33] <fsphil> radio should have been the first thing cyclops :)
[23:33] <cyclops> Funcube
[23:35] <cyclops> Well just saying, if I pickup the funcube and the computer i can still locate the payload
[23:35] <gonzo__> cyclops, yep any FM RX would work. This is just for the last 100mtrs. You won't be able to do any rtty decoding on FM, but you can hear the rx go quiet when you are beaming at the balloon (with a directional antenna) or just getting close (with a helical/whip)
[23:35] <cyclops> Just that Ill have to carry the equipment
[23:36] <gonzo__> get close to the landing area. use the FCD and laptop to pick up and decode the telem. That will give you an actual gps location. Then home in using a little FM rx.
[23:37] <M6PFX> fsphil: thanks for the pointers, i have it all working now and decoding the beacon text fine. heart attack over :)
[23:37] <cyclops> Can you point me to any link to see what im looking for?
[23:37] <gonzo__> Though I have found that just getting the telemetry of the actual landing point is enough. Then a hendheld GPS (on my phone) and just walk around till the lat/lon matches
[23:37] <fsphil> lol np M6PFX. it's nice to see data decoding
[23:38] <gonzo__> have found balloons in the pitch black dark that way
[23:38] <cyclops> Then i wont worry much
[23:38] Action: fsphil is watching a thunderstorm on http://www.blitzortung.org/Webpages/index.php?lang=en&subpage_0=12 -- slowly heading my way
[23:38] <cyclops> Im glad that here i probably wont have problems with the balloon in top of a tree
[23:38] <gonzo__> that is a common prob in the UK
[23:39] <fsphil> yea trees are not fun
[23:39] <cyclops> if trees are all arround like: http://www.dondeviajar.net/wp-content/uploads/2011/03/olivos1.jpg
[23:39] <cyclops> Thats the forest
[23:39] <cyclops> All arround andalucia, the most common
[23:40] <gonzo__> such a wrench to chase a hab, find it's location only to have to walk away becaus eit's in a tree,
[23:40] <daveake> <gonzo__> Though I have found that just getting the telemetry of the actual landing point is enough. Then a hendheld GPS (on my phone) and just walk around till the lat/lon matches
[23:40] <daveake> That's what I do
[23:40] <daveake> Once you have that landing position it's all easy*
[23:41] <daveake> *barring trees, rivers, ditches, nettles, angry farmers ...
[23:41] <daveake> cows
[23:41] <gonzo__> we found the one that came from south wales to sailsbury that way. we had a gps match and were looking at the tree line looking for a reflection off the torch. Then realised it was right in front of us within 6ft
[23:41] <daveake> 2m high maize
[23:41] <daveake> I walked into one payload
[23:42] <gonzo__> tx on floor, foil balloons at chest height
[23:42] <daveake> Couldn't see it at all
[23:42] <gonzo__> anghy cows!
[23:42] <cyclops> daveake: main radio is bought
[23:42] <cyclops> So ill follow your recommendations
[23:42] <cyclops> and gonzo__ '2
[23:42] <cyclops> *'s
[23:43] <daveake> I *much* prefer a real radio for chasing, however you can chase with what you have
[23:43] <cyclops> So ive allready spent a lot of money on this hobby
[23:43] <cyclops> Considering im at school
[23:43] <cyclops> So no salary
[23:44] <daveake> I understand; I'm just saying you would have (in my opinion) been better off spending £100-ish on a suitable scanner rather than more than that on a FCD
[23:44] <gonzo__> you can usually get the signal at a reasonable range. Thay may mean you can leave the laptop in the car and go out on foot with the handheld gps
[23:45] <daveake> Yes, I've always managed that
[23:45] <daveake> I wouldn't want to go hiking with a laptop if you can't get close enough
[23:45] <gonzo__> easier in the UK where there is little area between roads
[23:46] <cyclops> Ah for the car i bought a 50cm Antenna will that be enough?
[23:46] <cyclops> this one http://www.astroradio.com/113211.html
[23:46] <mfa298_> 50cm antenna should be fine if its designed for 70cms band
[23:47] <gonzo__> that one looks fine
[23:47] <gonzo__> is your FCD a new pro+ ?
[23:47] <cyclops> yes it is
[23:47] <gonzo__> good. Probably get away without an extra preamp
[23:47] <cyclops> Works really well
[23:47] <cyclops> Oh daveake
[23:48] <cyclops> I tested the camera interfereces on GPS 1575Mhz
[23:48] <gonzo__> saw one of the prototypes last year. Was really impressed. So brought one. (well another one!)
[23:48] <cyclops> measured with the funcube and yes it was emiting noise
[23:48] <mfa298_> and I'd agree with daveake and gonzo, once you've got telemetry from the balloon on the ground (be close enough as it comes down to recieve data) you'll have lat/long to put into a gps (just make sure you know how to use it)
[23:48] <gonzo__> useful test
[23:48] <cyclops> Shielded with 2 layers of ali and all gone
[23:48] <gonzo__> well done
[23:49] <cyclops> :D
[23:49] <cyclops> I think Im gonna have the best "pre university" project of my school
[23:49] <cyclops> So many solutions to find
[23:50] <cyclops> Ah and just in case the cameras will be shielded in a box 5m away from tracker as daveake suggested
[23:50] <gonzo__> if you do not have any internet/3g coverage in the landing zone, you shoudl make sure you have maps. And ones marked with lat/lon
[23:51] <cyclops> I think ill have
[23:51] <daveake> I don't think I said "5m"
[23:51] <cyclops> But ill bring just in case
[23:51] <daveake> Unless I meant "5 miles" :p
[23:51] <gonzo__> you feel so lost when you know the balloon is 'oer there somewhere' but your phone/laptop maps won't update
[23:51] <cyclops> oh sorry then daveake
[23:51] <cyclops> Then someone told me
[23:51] <daveake> Nah 5 metres should be fine :)
[23:51] <cyclops> Perfect :D
[23:52] <gonzo__> gn all.
[23:52] <cyclops> Im glad you guys advised me before putting cameras on the payload
[23:52] <cyclops> If not
[23:52] <cyclops> Who knows what could have happen
[23:53] <mfa298_> also make sure phone/laptop etc are properly charged and you can keep them charged. Running out of battery at the landing site is annoying
[23:53] <cyclops> inverter for the car
[23:56] <cyclops> And mobilephone charger
[23:56] <mfa298_> just as long as you remember to take them.
[23:57] <fsphil> hehe
[23:57] Action: fsphil forgot to bring the payload once...
[23:57] Action: mfa298_ realises he's up late again on a wednesday night, although no traipsing through fields with angry cows with week.
[23:58] <mfa298_> s/with/this/
[23:58] <fsphil> I really should be asleep but hoping this storm arrives soon
[23:58] <fsphil> gonna regret it when the alarm goes off
[23:58] <cyclops> Well guys thanks a lot for the help and imput
[23:58] <cyclops> Ill follow your recommendations
[23:58] <cyclops> Good night!
[23:58] <fsphil> nite!
