[08:16] <eroomde> a shame pico's don;t have cameras usually. I imagine you'd get some nice shots from bristolseds as the sun rose over the alps
[08:17] <SpeedEvil> It's not that hard to add.
[08:18] <SpeedEvil> But how the hell do you download.
[08:18] <SpeedEvil> Unless you're willing to wait and get under it with a HGA
[08:19] <eroomde> add it then
[08:19] <eroomde> i'll come back in a week
[08:19] <fsphil> heh, that's not a bad idea
[08:19] <fsphil> they don't have to be live
[08:20] <Vaizki> maybe it could just tweet overt JT9... "amazing! you guys should see this!"
[08:20] <eroomde> indeed
[08:20] <SpeedEvil> I just mean the camera bit is about an order of magnitude or two easier than the downloads
[08:20] <fsphil> yeah
[08:20] <eroomde> yeah
[08:20] <eroomde> i agree - getting them back through aprs is probably not going to happen
[08:20] <fsphil> the little sensors are stupidly light weight too
[08:20] <fsphil> you could easily to small thumbnails through aprs
[08:21] <SpeedEvil> http://www.ebay.co.uk/itm/New-Smallest-Mini-Camera-Camcorder-Video-Recorder-DVR-Spy-Hidden-Pinhole-Web-cam-/151924221526?hash=item235f63a656:g:6LcAAOSwJcZWeRZc - hah
[08:21] <eroomde> maybe, if uplinks become more of a thing, there could be some option for high bandwidth dumps
[08:21] <SpeedEvil> I guess that'd strip to 5g.
[08:21] <eroomde> some italian in the next few hours could say 'hit me'
[08:22] <eroomde> fsphil: ah yes - if there were thumbs then you could uplink which one you want sent back
[08:22] <fsphil> yeah. pick and choose what looks good
[08:24] <SpeedEvil> I did a simple design with a mobile cam, and got it down to ~3g IIRC
[08:24] <SpeedEvil> that used a now-unobtainable nice JPEG camera chip
[08:24] <SpeedEvil> (the chip output JPEG, it wasn't one of the serial JPEG ones)
[08:24] <fsphil> there are a few of those still about
[08:24] <eroomde> yeah i assume one now has to compress with the application processor
[08:24] <SpeedEvil> eroomde: pretty much
[08:25] <fsphil> doing the jpeg bit on the micro is pretty simple though
[08:25] <eroomde> but, i have written a jpeg compressor before in undergrad. how hard can it be to do in c!
[08:25] <SpeedEvil> eroomde: Oh - it's not
[08:25] <fsphil> just has to be fast enough so you don't need the entire raw image in ram
[08:25] <SpeedEvil> the nice part was it also reduced storage bandwidth
[08:27] <fsphil> external ram is quite power hungry
[08:27] <eroomde> you can do jpeg compression as a stream?
[08:27] <eroomde> i'd have thought you need the whole thing
[08:27] <fsphil> yeah, you can work on 8-pixel high lines
[08:27] <fsphil> at a minimum
[08:27] <fsphil> so you'd need width x 8 pixels to start
[08:28] MarkIreland (~MarkIrela@host31-54-150-195.range31-54.btcentralplus.com) joined #highaltitude.
[08:29] <fsphil> each jpeg block is independent for the most part, only needing a small bit of data from the previous one
[08:30] <fsphil> and the block can be 8x8, 8x16, 16x8 or 16x16 pixels in size
[08:30] <SpeedEvil> fsphil: 16 high blocks
[08:30] <SpeedEvil> oh
[08:30] <SpeedEvil> 8 high if greyscale
[08:30] <SpeedEvil> http://www.st.com/web/en/catalog/mmc/FM132/SC1056 - for example
[08:30] <fsphil> nah, even colour has 8x8 mode
[08:30] <SpeedEvil> All of these are now CSI or some other silly mode
[08:31] <SpeedEvil> which requires you to have a multi-hundred-megabit serial interface
[08:31] <fsphil> which is higher quality too, as it doesn't then reduce colour resolution
[08:31] <fsphil> but larger images

[10:33] <mfa298> more believable if the ordering system / purchasing dept changed the m to M without realising the significance
[10:33] <gonzo_> and each dept adds their cut

[10:41] <Laurenceb_> Geoff-G8DHE_: I downloaded the klm from habitat
[10:41] <Laurenceb_> forgot how sorry :P
[10:41] Action: Laurenceb_ was looking at float altitude and pressure
[10:41] <eroomde> kml not klm
[10:41] <eroomde> if you look at klm in google earth you'll wonder why the path keeps going to airports
[10:42] <Laurenceb_> dyslexia++
[10:42] <Geoff-G8DHE_> Yes I have it too, but I wanted a simple easy to get at picture for someone who is interested, there was a page on the tracker at one point
[10:42] <Laurenceb_> ah
[10:42] <Geoff-G8DHE_> I have my own images as well but thought it would be an easy introduction if it was using the Tracker!
[10:42] <Laurenceb_> I don't know sorry
[10:42] <Geoff-G8DHE_> lz1dev, ?
[10:43] <Laurenceb_> you need adamgreig
[10:43] <Laurenceb_> lz1dev runs the graphs site
[10:43] <Geoff-G8DHE_> Is the B64 page still available on the tracker ?

[10:46] <Oddstr13> speaking of horrible technology, that bbc link requires flash to play

[10:56] <lz1dev> Geoff-G8DHE_: what are you looking for?
[10:59] <Geoff-G8DHE_> On the tracker spacenear.us site you had a page that showed just the B64 flight ?
[10:59] <Geoff-G8DHE_> Is it still there ?
[11:00] <lz1dev> no
[11:00] <lz1dev> just find the flight id
[11:00] <Geoff-G8DHE_> Ah OK, guessed that might be it.
[11:00] <lz1dev> and put in the tracker

[11:06] <eroomde> it's a chip remover
[11:06] <eroomde> observe different colour handle
[11:06] <mfa298> if only I could get something like that at work and know that they'de all be there a week later, (Getting it wouldn't be too much of an issue, stopping some of them walking off to never return would be)
[11:08] <eroomde> you just have to be scary
[11:08] <eroomde> then the tools tend to stay put

[11:17] <eroomde> seeing that photo reminds me that there is no ELSA (the yellow thing on the window sill) in the lab anymore
[11:17] <eroomde> i should fix it
[11:17] <SpeedEvil> Very expensive test gear, and old very expensive test gear
[11:17] <eroomde> Oddstr13: i had a tidy!
[11:18] <SpeedEvil> Oooh - and top left I think is my scope
[11:18] <eroomde> an old hameg i got from uni
[11:18] <SpeedEvil> oh - no then
[11:18] <eroomde> when they were giving them away
[11:18] <eroomde> i am going to take it to my home lab actually
[11:18] <eroomde> i like having it around especially when you are worried about putting badness into a pricier scope
[11:19] <SpeedEvil> I thought it was a Tek 475A
[11:19] <SpeedEvil> Or similare
[11:19] <eroomde> no, though there is a tek 465 out of shot on the right

[11:20] <eroomde> literally a scorpion FuzzyLemon?
[11:21] <SpeedEvil> They have great visual memory
[11:21] <AndyEsser> eroomde: wait... is that the room I saw on Saturday?
[11:21] <eroomde> yes
[11:21] <AndyEsser> wow
[11:21] <eroomde> like i said, it is somewhat less tody there now
[11:21] <FuzzyLemon> unfortunately no. that's just the project name
[11:21] <AndyEsser> that's an understatement :)
[11:21] <eroomde> we just finished a cool thing but it does look a little bombed

[11:24] <AndyEsser> I need to organise mine better
[11:24] <AndyEsser> and get some storage
[11:24] <eroomde> i bet he has morte monitors tho
[11:24] <daveake> that's a very wide-angle lens
[11:24] <AndyEsser> eroomde: yes, currently only have 2 up and running
[11:25] <AndyEsser> got 2 more in the spare room I should use
[11:25] <AndyEsser> but don't really have space atm
[11:25] <eroomde> i wouldn't mind another
[11:25] <eroomde> but no great urgency
[11:25] <eroomde> it costs about the same to get another of the ones i have as it does to get a nice toolchest
[11:25] <eroomde> the latter of which is much more important atm
[11:26] <AndyEsser> I'd like to get another 27" to match my other one

[11:28] <gonzo_> is it like trying to use one of the toy cars that you used to have to rev up on the floor to get the fly wheel going
[11:29] <daveake> less than the width of the mousepad if I move it slowly; a lot less if quickly

[11:31] <AndyEsser> haha
[11:31] <AndyEsser> done that before
[11:31] <daveake> Ah, there's a solution for that
[11:31] <AndyEsser> used to have 2 PC's (+ laptop) at my last job

[11:33] <daveake> gonzo_ No, only time I've had to reconfigure which monitor is which is when I've moved house and connected them up in a different order
[11:35] <gonzo_> we have probs at work where the monitors lose their id and come up as generif 640-480. And windows moves all the icons
[11:35] <gonzo_> you have to mains power the monitor down for at least 40sec.
[11:36] <daveake> Ah, no, not had that at all
[11:36] <daveake> Only issue is sometimes a monitor doesn't come up from power-save
[11:36] <gonzo_> it ruined IT's day whgen it first happened
[11:36] <daveake> So I catrl-alt-del then press ESC, and it's fine

[11:47] <fsphil> love the curved shelf too daveake
[11:47] <eroomde> i am sticking to my wireless keyboard in my home lab but i will be looking closely for evidence of inteference
[11:48] <fsphil> I don't trust wireless keyboards enough to enter passwords on. computer security has made me paranoid :)
[11:48] <daveake> Well angled rather than curved, but yeah that's nice. I put all my working-on Pi boards up there
[11:48] <daveake> plus PSU and network switch and HDMI switch
[11:49] <eroomde> if i did replace it it's have to be a nice mechanical one
[11:49] <eroomde> with shielded usb cable
[11:49] <daveake> that shelf was the key to clearing the desk top
[11:50] <fsphil> having the shelf for the psu and scope has made quite a difference here

[11:51] <Darkside_> yeah
[11:51] <Darkside_> this time there'll be lora hardware in both chase cars
[11:52] <Darkside_> so we should be able to chat to each other
[11:52] <Darkside_> and there'll be a few other ground stations too
[11:52] <eroomde> i sort of prefer my plastic rotring tikky to my rotring rapid pro metal thingamie

[11:58] <eroomde> a bunch of squiggles moving vertically up a screen and you saying 'heh look at that ethernet cable'
[11:59] <Oddstr13> well, I unplugged it, and a bunch of the noise disappeared :P
[12:00] <fsphil> turning off everything in your house can help
[12:00] <fsphil> you won't hear any interference at all
[12:00] <Oddstr13> ofcourse!
[12:01] <Oddstr13> cause that includes the receiving gear..
[12:01] <gonzo_> it's a bugger that the RF environment is getting noisier, but I often find that being the person moth the most electronic crap running, it's usual;ly me generating it
[12:01] <fsphil> hehe yeah
[12:01] <Oddstr13> oh, I know I'm generating a huge chunk of what noise I'm seeing :P
[12:02] <fsphil> my APC UPS boxes are quite RF noisy
[12:02] <fsphil> even when they're on standby
[12:02] <gonzo_> even buying ferrites by the bucket, it's still a battle to keep it under control
[12:02] <daveake> I remember making an MSF receiver when young. Couldn't get the damn thing to work. Then parents switched off the TV and the receiver sprang into life.
[12:02] <fsphil> oh the old CRTs used to wipe out LW and MW reception
[12:03] <gonzo_> I built a simple specan as a kid, using a tv tuner block, swept using a mains transformer
[12:03] <Oddstr13> switches, routers, PCs, HDMI monitors, power adaptors by the bucketloads
[12:03] <daveake> 60kHz ... not far off the CRT line refresh
[12:03] <Oddstr13> oh, and all the CAT5e UTP
[12:03] <gonzo_> worked well, but the sweeping LO was putting bars on all the TVs in the street
[12:03] <fsphil> I made a point of installing sheilded cat5 at the new house
[12:03] <fsphil> it does seem to have helped
[12:03] <daveake> modern power bricks are often pretty bad
[12:04] <gonzo_> the soladin 600 was awful on hf
[12:04] <fsphil> yeah
[12:04] <fsphil> mine's currently in storage
[12:04] <gonzo_> killed <10MHz s9+lots
[12:04] <fsphil> not sure I'll put it back on
[12:05] <gonzo_> good shatfner filters on the dc side work
[12:05] <Oddstr13> daveake: I actually have yet to identify any noise directly caused by the power bricks I have
[12:05] <fsphil> walk around your house with a small antenna, make a heat map
[12:05] <fsphil> I think Darkside_ did something like that once?

[12:09] <fsphil> oh neat
[12:10] <daveake> Dunno if anyone else saw it, but during one of last week's Stargazxing shows they had an article about a radio telescope where they have a roving "interference sniffer" bloke who drives round with a discone on the roof and various radio scanners/spectrum analysers bolted to the dash
[12:10] <Oddstr13> what's the bandwith on DRM?
[12:10] <fsphil> usually 9 or 10khz
[12:10] <fsphil> that's not DRM
[12:11] <Oddstr13> probably my old friend the OTH radar then
[12:11] <fsphil> http://spectrafold.com/quadrus/wp-content/uploads/sites/2/2015/02/drm04.jpg
[12:11] <fsphil> DRM is like DAB but narrower
[12:12] <Oddstr13> possibly pluto
[12:12] <Oddstr13> http://www.sigidwiki.com/wiki/PLUTO_II_Radar
[12:13] <fsphil> doesn't look that similar
[12:13] <Oddstr13> it's a weak signal
[12:13] <Oddstr13> sounds about the same as the samples
[12:13] <Oddstr13> and the bandwidth is about right I think
[12:14] <Oddstr13> and I have seen it in the past
[12:14] <fsphil> frequency is too low
[12:14] <fsphil> oh the frequency varies
[12:14] <fsphil> could be then

[12:18] <Oddstr13> 85cm antenna, what frequency would that be optimal for?

[12:21] <Oddstr13> chinese by the sound of it
[12:23] <gonzo_> 85cm is aboyt 88mhz
[12:23] <Oddstr13> so, fm
[12:23] <gonzo_> or 3x that for a 3/43wavelength
[12:23] <gonzo_> 3/4
[12:24] <gonzo_> pretty much yes
[12:24] <Oddstr13> so, the antenna that comes with the hackrf is optimal for FM reception :P
[12:24] <Oddstr13> at full length
[12:24] <gonzo_> if telescopic, you can adjust it to suit
[12:25] <Oddstr13> yea, but only up in frequency
[12:25] Mack (~Mack@unaffiliated/mack) left irc: Ping timeout: 245 seconds
[12:25] <fsphil> the hackrf is not brilliant at low frequencies anyway
[12:25] <fsphil> though it can work there which was a bit of a surprise
[12:25] <Oddstr13> nor is the RTL-SDR :P
[12:25] <gonzo_> but as an indoor antenna, screwed to the sid eof a pcb, it's goinbg to be pretty poor, so adjusting it to tune is not going to make much difference

[12:29] <gonzo_> if it's straight multiples, rather than mixing products, just divide it
[12:30] <Oddstr13> cause I'm seeing AM radio on 33.65MHz :P
[12:31] <gonzo_> it's unlikely that is a straight harmonic, unless you are overdriving the RX badly

[12:40] <Oddstr13> apparently it's transmitted at 500kW from Urumqi, 5130km-ish from here
[12:41] <R34lB0rg> could a hab possibly connect to a ground based open wlan? using a highly directional antenna?
[12:42] <gonzo_> you would need a huge antenna on the ground
[12:42] <fsphil> yes. but with great difficulty
[12:42] <gonzo_> and airborn 2.4ghs will be limited to 10mW
[12:43] <R34lB0rg> i thought about acessing open wlans below as they come and go
[12:43] <fsphil> never gonna happen
[12:43] <fsphil> unless you're floating at 20m above ground
[12:43] <craag> even then you'd struggle at wind speed to associate in time I bet
[12:44] <fsphil> even then, how many open wifi points do you see anymore?
[12:44] <R34lB0rg> people are using wlan links over much greater distance without even a directional antenna
[12:44] <fsphil> no they're not
[12:44] <Oddstr13> oh, normal wifi antennas are rather directional
[12:44] <AndyEsser> Cantenna :)
[12:44] <fsphil> you'll get tens of metres tops with omni directional antennas
[12:45] <craag> you can do 50-100m in free space, outdoors, no obstructions, etc
[12:45] <Oddstr13> good luck getting a reliable connection to a wifi router on the floor directly below, with the antenna pointing straight up
[12:45] <Vaizki> you don't want normal wlan anyway.. it depends on AP-Client association and if that falters the link drops and you are screwed

[12:46] <fsphil> I would still like to try wifi - to transmit the video of the launch from the payloads point of view
[12:46] <R34lB0rg> Vaizki, not for tracking anyway, but would be fun to have a webserver in the stratosphere
[12:46] <fsphil> it should remain in contact for a minute or so
[12:46] <Oddstr13> I've been able to associate with wifi as a passenger of a car, but that is rather challenbging too
[12:46] <fsphil> you'd want to fly the AP on the payload
[12:46] <fsphil> see if people on the ground can connect to it
[12:46] <fsphil> not the other way around
[12:47] <Vaizki> there is a hack of using wifi L2 to stream video without association
[12:47] <Vaizki> was discussed here before, https://befinitiv.wordpress.com/wifibroadcast-analog-like-transmission-of-live-video-data/
[12:47] <fsphil> I remember that. never did get a chance to try it
[12:47] <gonzo_> use a good rx with lna on the ground and a decent antenns (3mtr dish...)
[12:48] <fsphil> one of those collapsable umbrella dishs would be handy
[12:48] <Oddstr13> I actually have a rather big dish antenna lying around
[12:48] <Vaizki> with normal wifi good rx is not enough
[12:49] <Oddstr13> was used as a satelite uplink on a shell petrol station in the past
[12:49] <Vaizki> because if the payload doesn't hear you back, it loses the association
[12:49] <gonzo_> I am still mourning the passing of mine. But it was never going to be used
[12:49] <fsphil> I've a 1.2m dish in the garage I'd like to try with the hackr
[12:49] <fsphil> +f
[12:49] <gonzo_> I even cleared out the 1.6mtr and 5ft ones
[12:50] <gonzo_> 1.2mtrs is a useable gain at 2.4GHz
[12:50] <gonzo_> (look at G6LVB site, he has sone good info for feeds to 2.4GHz dishes, for amsat work)
[12:51] <fsphil> I think the hackrf works up to 6ghz, wonder if there's any deep space stuff on those frequencies
[12:51] <gonzo_> mainly at 8GHz
[12:52] <Oddstr13> oh, that's rtty, time to take out fldigi :3
[12:52] <fsphil> mmm rtty at 8ghz :)

[13:13] <R6mco> ok..
[13:13] <R6mco> there is a trick for that
[13:14] <R6mco> you want to run both JT65 and JT9 ?
[13:14] <R6mco> for the HAB version, choose 1.6 - devel of wsjtx from the picospace site
[13:14] <Oddstr13> oh, it was just that WSJT-X is using a lock file, probably in %APPDATA% somewhere
[13:15] <Oddstr13> both versions where using the same lock file
[13:15] <R6mco> okidoki
[13:16] <R6mco> I run two instances of WSJTX here. One (tries to) decode JT9 and upload it to habhub.org and pskreporter.info, the other instance decodes wspr and uploads it to wsprnet.org

[13:25] <Vaizki> confusion!

[13:26] <R6mco> tune rx to 9996.000 kHz , or 9.996000 MHz
[13:27] <R6mco> ok, when you listen to the carrier, you hear 'dots' ?
[13:27] <Oddstr13> it's worth noting that my antenna isn't even remotely suited for these frequencies
[13:27] <R6mco> doesn't matter, that's of later issue.. RWM is now transmitting dots
[13:27] <Oddstr13> hang on, let me turn back on audio
[13:28] <Vaizki> there should be 100ms blips every second
[13:28] <Vaizki> and a 500ms blip when minute changes
[13:28] <R6mco> something like that indeed
[13:28] <Oddstr13> nope, that is a solid signal
[13:28] <R6mco> hmm
[13:28] <Oddstr13> oh, there it is
[13:29] <R6mco> make the frequency span smaller
[13:29] <AndyEsser> is that time signal worldwide?

[13:29] <R6mco> AndyEsser: RWM is quite strong, there are other time signals, see wikipedia
[13:29] <gonzo_> they prob want to avoid clashing with the us time signal on 10MHz
[13:29] <R6mco> Oddstr13: stretch out the spectrum , thus a smaller freq span
[13:30] <Vaizki> my closesti time signal is a 25MHz one from about 4km away, Finnish research institute standards department

[13:30] <R6mco> Oddstr13: perfect
[13:31] <Vaizki> looks spot on
[13:31] <R6mco> nou determine the freq of that signal, i.e. the freq your receiver thinks it is
[13:31] <Oddstr13> I have in fact tuned it before :P
[13:31] <Oddstr13> -8 ppm
[13:31] <R6mco> not ppm, first the frequency
[13:31] <Oddstr13> my rtl-sdr is something like +38 ppm
[13:32] <R6mco> (we take the simple method... because you want to look near 10 MHz to the balloons)
[13:33] <Oddstr13> I have adjusted the ppm in the past, in relation to the fm broadcast band
[13:33] <R6mco> yep, that is not good enough
[13:33] <Oddstr13> are you saying I should use the shift option in SDR# instead?
[13:33] <R6mco> therefore I ask for the frequency you now determine of the time signal
[13:34] <R6mco> and make the frequency span larger , whole display 5 or 10 kHz or so
[13:34] <Oddstr13> should I reset ppm then?
[13:34] <R6mco> do nothing , just what I ask you to ; -)
[13:35] <Oddstr13> should probably turn down sample rate then
[13:35] <Vaizki> I think you want the sampled span to be smaller and increase resolution of FFT so see more precisely where the peak is?
[13:35] <R6mco> yep
[13:35] <Vaizki> just trying to interpret here :)
[13:35] <R6mco> it has to be around 1 Hz precise (that's perfect)
[13:36] <R6mco> RTL is not vy stable, but when you've good calibrtion, you can live with it

[13:40] <R6mco> ok .. the red line is not in the middle of RWM
[13:40] <R6mco> can you determine the frequency of the peak with an accuracy of 1 Hz ?

[13:41] <Oddstr13> I can hear the pulses
[13:41] <R6mco> ok
[13:41] <Oddstr13> I don't get better resolution that this tho
[13:41] <R6mco> when you can hear the pulse and you are tuned to '9996.000' than this is NOT good
[13:41] <Oddstr13> I am within 100Hz atleast
[13:41] <Oddstr13> oh, I switched to CW mode
[13:42] <R6mco> do NOT switch to CW
[13:42] <R6mco> stay on USB
[13:42] <Oddstr13> currently with a 100Hz filter around center frequency
[13:42] <R6mco> no filters
[13:42] <R6mco> you need zero beat frequency when you cant determine the freq of the RWM peak
[13:43] <R6mco> use normal USB (i.e. 3 kHz BW or so)
[13:44] <Oddstr13> I don't get a much better waterfall than this
[13:44] <R6mco> ok
[13:44] <R6mco> we need to redefine starting position
[13:45] <R6mco> because too many variables changed
[13:45] <R6mco> and we are 1000 km apart & can't see each other, nor I see your display ; -)
[13:46] <Oddstr13> how precise does the tuning need to be?
[13:46] <R6mco> so please (if you want calibration, ofc) do exactly as I advise
[13:46] <R6mco> deal?
[13:46] <Oddstr13> sure
[13:46] <R6mco> ok
[13:46] <R6mco> <- not slave mode anymore, now Master ;;; -)
[13:47] <R6mco> what is 'the frequency' you typed in in SDR# ?
[13:47] stheory (~nic@ joined #highaltitude.
[13:47] <Oddstr13> I am offset tuning, so to say
[13:47] <Vaizki> I don't get how you can use sdr# to get the frequency down to a 1Hz.. :)
[13:47] <R6mco> argh..
[13:48] <R6mco> ok, offset tuning ... *think*
[13:48] <R6mco> another approach :
[13:48] <R6mco> tune to 9996.000 kHz
[13:49] <Oddstr13> zoomed out view: https://dl.dropboxusercontent.com/u/4306267/ShareX/2016/01/2016-01-21_14-48-45.png
[13:49] <R6mco> so 'type' 9996.000 kHz somewhere in your SDR program
[13:49] <Oddstr13> solid red line in the middle is my actual radio frequency
[13:49] <Vaizki> no it's your virtual VFO frequency
[13:49] <R6mco> red line around 12 MHz ? )
[13:50] <Oddstr13> yea
[13:50] <R6mco> Vaizki: indeed, that's the point I want to make)
[13:50] <R6mco> ok
[13:50] <Oddstr13> if you want me to put that line on top of the time signal, I won't see said time signal at all
[13:50] <Vaizki> right, zero peak hides it
[13:50] <R6mco> Oddstr13: understood
[13:51] <R6mco> you now listen in LSB by the way
[13:51] <Vaizki> or central spur or whatever you call it
[13:51] <R6mco> your 0 is above 9996 kHz
[13:51] <R6mco> anyway
[13:51] <Oddstr13> nope, still USB
[13:52] <Oddstr13> what I'm actually listening to dosn't have anything to do with that center frequency
[13:52] <R6mco> (yeah... USB, but I/Q are reversed so that you think you listen in USB) ; -) , but never mind
[13:52] <R6mco> ok, decrease the span
[13:52] Johnwulp (~Johnwulp@dhcp-077-248-223-039.chello.nl) left irc: Quit: Bye
[13:52] <R6mco> so that 9996 kHz is in the center of your waterfall
[13:53] <R6mco> and your span is as low as possible (preferably a few 100 Hz or so)
[13:53] <Oddstr13> I don't get better resolution from that in SDR#
[13:54] <R6mco> ok, said in another way ... are you able to ascertain the frequency of the time signal within a resolution of 1 Hz (or ... somewhat worse .. 10 Hz ) ?
[13:55] <Oddstr13> https://dl.dropboxusercontent.com/u/4306267/ShareX/2016/01/2016-01-21_14-55-20.png
[13:55] <R6mco> in other words, you not knowing that the time signal is at exactly 9996.000 kHz and you tune in to it, what frequency do you think it is?
[13:55] <Oddstr13> tuned 1k below, that's what it looks like in dl-fldigi
[13:56] <R6mco> yeah.. that is a method .. not accurate enough.. but at least we're somewhere : -)
[13:56] <R6mco> ok .. you determine RWM freq as 9995.96(0) kHz
[13:56] <R6mco> this is 40 Hz too low
[13:57] <R6mco> 40 +/- 10 Hz , let's use 40 Hz

[14:04] <Oddstr13> yes?
[14:04] <R6mco> ok.. on the right you see 'intercept'
[14:04] <R6mco> it is now 0.00 Hz
[14:04] <Oddstr13> indeed
[14:04] <R6mco> ok..
[14:04] <R6mco> let me think
[14:04] <R6mco> type -40.00
[14:04] <R6mco> press OK
[14:05] <R6mco> and see in the waterfall if the peak is at 1000 Hz
[14:05] <R6mco> of it is lower than the first, remove the '-' from 40
[14:05] <Oddstr13> peak didn't move
[14:05] <R6mco> hmm
[14:06] <R6mco> ok
[14:06] <Vaizki> I tried SDR Console V2 to check RWM.. this is the best I can do.. tuned to 9995.500 and looking at audio spectrum on USB
[14:06] <Vaizki> http://i.imgur.com/SA0IecG.jpg
[14:06] <Oddstr13> also, it's more like 7-8Hz off
[14:06] <Vaizki> seems to be spot on 500Hz but no way to tell for sure in SDR Console
[14:06] <R6mco> ok .. fair enough ... lets assume that you're reasonably good on frequency
[14:06] <R6mco> (can be tweaked later)
[14:07] <R6mco> (also read the WSPR manual)
[14:07] <R6mco> (later ... ;-)

[14:07] <R6mco> close
[14:07] <R6mco> (settings window)
[14:08] <Vaizki> R6mco, to check your own gear frequency, you use a spectrum analyzer on the IF?
[14:08] <R6mco> Vaizki: no, I use a GPS locked oscillator and a very precise receiver
[14:09] <Vaizki> yea I have a GPSDO as well.. so you use the GPSDO as an ext ref?
[14:10] <Oddstr13> R6mco: what next?
[14:10] <R6mco> ok..
[14:10] <R6mco> Oddstr13: tune your RX to 10.138700 MHz
[14:11] <Oddstr13> so, mode WSPR-2, 30m
[14:11] <R6mco> yep
[14:11] <R6mco> select 30m

[14:20] <R6mco> Oddstr: read the URL Vaizki gave, and do accordingly
[14:20] <R6mco> yes, you can
[14:20] <Oddstr13> if it only displayed the error, it would be fine
[14:20] <R6mco> if I can do it, you can do it
[14:20] <Oddstr13> my hardware "RTC" is running UTC time
[14:20] <Oddstr13> and windows is set up to recognize this fact
[14:20] <Vaizki> everyone's is

[14:20] <Vaizki> or they are crazy
[14:21] <Oddstr13> Vaizki: if you are running widnows, you most probably arn't
[14:21] <R6mco> Oddstr13: 1000's of people run rsNTP on Win
[14:21] <R6mco> so PLEASE .. if you want this to work properly ?
[14:22] <Oddstr13> R6mco: there is a bug in windows 7, which causes the hardware time to be set to local time, rather than UTC as it is supposed to
[14:22] <Oddstr13> if time is adjusted by windows
[14:22] <Oddstr13> it will then be 1h off on next boot
[14:22] <R6mco> I give up
[14:23] <R6mco> apperantly you have a very special version of windows ... not able to WSPR, I think that's the case
[14:24] <Oddstr13> fine, I'll run the goddamn thing, but I blame you if my system time is off by 1h next time I boot >,<
[14:24] <R6mco> wait
[14:24] <Vaizki> :)
[14:24] <Vaizki> :D
[14:24] <R6mco> first switch off internet timing
[14:25] <R6mco> the tab where it is synced to an internet NTP server
[14:25] <Oddstr13> in windows time settings?
[14:25] <R6mco> yep
[14:25] <R6mco> rsNTP handles the timing
[14:25] <Vaizki> and yes Oddstr13 it seems you are right, windows hates utc rtc.. didn't know that. I mostly use a Mac..
[14:25] <Oddstr13> allready turned off, due to bug I just refered to

[14:45] <Oddstr13> nope
[14:46] <Oddstr13> do see some weak JT65 a bit further up tho

[14:47] <R6mco> do you have audio ?
[14:48] <Oddstr13> I am listening to the noise, yes
[14:48] <R6mco> i.e. you hear noise ?

[14:48] <Oddstr13> HackRF standard antenna, as stated earlier.

[14:53] <R6mco> nah
[14:53] <R6mco> that's for later
[14:53] <R6mco> first important is to make an antenna suitable for the 10 MHz wavelength
[14:53] <R6mco> (i.e. 30m , so 6.85 m is around 1/4 wl)
[14:55] <R6mco> main goal for now is: you receive WSPR traces (otherwise you're not able to rx PS-58 at all )
[15:01] <R6mco> and ... ?
[15:03] <Oddstr13> can't say I see much of a difference
[15:03] <R6mco> you experience not more noise ?
[15:04] <Oddstr13> I do see some rtty further down in the band
[15:05] <R6mco> ok, we take the more easy approach then
[15:05] <R6mco> select JT-65
[15:06] <R6mco> change frequency on your receiver to 10.138000 MHz
[15:06] <R6mco> thus 700 Hz lower
[15:07] <R6mco> chose 3 or 4 bin/pixel and start freq = 200 Hz in the waterfall

[15:15] <Oddstr13> noise is the name of the game! :P
[15:16] <Oddstr13> still seeing that rtty at 10.100 MHz, but nothing much other than that
[15:20] <Oddstr13> https://dl.dropboxusercontent.com/u/4306267/ShareX/2016/01/2016-01-21_16-20-09.png the bigger picture if you like
[15:22] <gonzo_> noise picked up at the antenna is the prob at HF. But generally the signals are strong that noise inside the RX is not an issue. But V/UHF the internal noise starts to affect the SRN
[15:22] <gonzo_> SNR
[15:22] <R6mco> yeah that rtty signal is the Deutsche Wetterdienst
[15:22] <Oddstr13> yea, kinda figured
[15:22] <R6mco> Oddstr13: indeed, noise reduction and SNR improvement is indeed the name of the game
[15:23] <Oddstr13> I allways tend to use forewer to find the right mode to decode that one
[15:23] <AndyEsser> Python people - is it possible to use ipython notebook to constantly redraw a plot, and change values? (in like a textbox)
[15:23] <R6mco> Oddstr13: so now your challenge is : reduce noise
[15:24] <R6mco> and try to decode wspr traces
[15:24] <R6mco> otherwise no PS-58
[15:24] <Oddstr13> step one: move the HackRF
[15:24] <Oddstr13> anyways, how is propagation at 30m?
[15:25] <R6mco> 30m is in fact an ideal band for world wide propagation
[15:25] <gonzo_> because noise and signals are big on HF, antenmna effciciency is not that important. But redicing the picked up noise is. On higher freqs though, the signals are weaker, so efficiency is important. But gain and directionality are easier to get. Also electriccal noise tends to be lower at higher freqs
[15:25] <R6mco> gonzo_: indeed, that's the issue/case
[15:25] <Oddstr13> in relation to time of day I mean
[15:25] <Oddstr13> cause it is starting to get dark here now
[15:25] <R6mco> Oddstr13: I could rx PS-57 and PS-58 during the days and grey line
[15:26] <R6mco> sunrise and sunset are good DX times, google on grey line
[15:26] <R6mco> (of gray line, not the busses ;-)
[15:26] <Oddstr13> I know from before that CB drops out at (or before) this time
[15:26] <R6mco> ok, resume:
[15:26] <R6mco> 1. you are on time
[15:27] <R6mco> 2. freq of receiver is fine enough
[15:27] <R6mco> 3. you're able to decode JT65 traces with your setup
[15:27] <R6mco> to do:
[15:27] <R6mco> 1. reduce noise / make better antenna
[15:27] <Oddstr13> I knew I was able to decode JT65 :P
[15:27] <R6mco> 2. try to decode WSPR traces
[15:29] <R6mco> when you decode wspr traces, check 'upload spots'
[15:29] <R6mco> and check if your spots are reported on wsprnet.org database

[15:37] <R6mco> yep
[15:37] <R6mco> 10.1387
[15:37] <R6mco> you need this freq for JT9 also, wspr is between 1400 - 1600 Hz then
[15:38] <Oddstr13> that would put it just above 2100 now then

[15:40] <R6mco> thus set your RX to 10.138700 MHz in USB (this is called the 'dial frequency')
[15:41] <Oddstr13> why am I not allowed to manualy input frequency in WSJT-X? :(
[15:41] <R6mco> because this is standardised
[15:41] <R6mco> otherwise people report wrong frequencies
[15:41] <R6mco> there is a so called band plan
[15:42] <R6mco> these weaksignal modes was very narrow band, therefore frequency precision (and timing) is so important
[15:43] <R6mco> was = are*
[15:43] <R6mco> if you are 100 Hz off... you may receive nothing
[15:43] <R6mco> (or better... decode nothing)
[15:44] <Oddstr13> dosn't matter, I am easily able to receive both WSPR and JT65 within the same bandwith
[15:44] <Oddstr13> I should be able to tell WSJT-X that my dial frequency is 700Hz lower than the standard
[15:45] <R6mco> yes ... and no ...
[15:45] <Oddstr13> anyways; 1542 -20 1.3 10.140179 1 G7EVW IO94 37 1109
[15:45] <R6mco> the IIR filters in the software for WSPR have been optimised for 1400 - 1600 Hz
[15:45] <R6mco> ok ..
[15:45] <R6mco> you had a succesfull decode, did you check 'upload spots' ?
[15:46] <Oddstr13> I just did now
[15:46] <R6mco> grr... this wsprnet.org database has continuous hiccups
[15:47] <R6mco> ok, when you just did, that spot is not uploaded, wait for another one
[15:47] <Oddstr13> fully aware
[15:47] <Oddstr13> I've gotten two more in the meanwhile
[15:47] <Oddstr13> still getting JT65 with JT65-HF
[15:48] <R6mco> yeah.. of course

[16:00] <Oddstr13> dosn't look like it
[16:00] <R6mco> I can't see spots of you on wsprnet.org Oddstr13
[16:02] <R6mco> GM4SFW is often strong and on .280 , thus 1580 Hz <- he has GPS locked wspr TX
[16:03] <R6mco> good reference
[16:08] <R6mco> ok, I am off, have an appointment at 1800 hrs here
[16:11] <Oddstr13> the wsprnet website is painfully slow at best

[16:12] <Oddstr13> are they getting DDoS'd, or is the server running on a Pi?

[16:13] <R6mco> too much traffic and old backend indeed
[16:13] <R6mco> it's a nuisance

[16:18] <R6mco> PA3MET is a friend of mine BTW, he lives 15km more south than me
[16:19] <R6mco> ok, and I see you live very in the north of .no
[16:19] <Oddstr13> not really
[16:19] <R6mco> must be a quiet (low noise) place anyway, far better than my location
[16:20] <Oddstr13> not even halfway to the north of norway :P
[16:20] <R6mco> ah yeah.. I see, .no extends further ; -)
[16:20] <R6mco> jaja, I see, I was too quick
[16:20] <Oddstr13> but, yea, most of the noise is local from my computer network

[16:48] <richardeoin> not quite that one, but something similar

[16:52] <richardeoin> it's mostly here https://github.com/bristol-seds/pico-tracker/blob/master/sim/geofence/geofence.ipynb
[16:54] <richardeoin> there's some functions that attempt to transform it onto an equal area grid using pyproj, but I don't think it quite works
[16:55] <AndyEsser> Woo - as of Monday, will have a company car - that'll make chases a bit easier :)
[16:55] <richardeoin> hence being a bit overzealous with the 25km of terratorial waters and cutting off the whole adratic
[16:56] <richardeoin> Nice AndyEsser, cars definietly make real balloons easier
[16:57] <richardeoin> one of the reasons us university students do picos launches
[16:57] <Laurenceb> thats quite impressive work
[16:57] <Laurenceb> so you project out along the normals?

[19:27] <Lunar_Lander> hi AndyEsser
[19:31] <eroomde> AndyEsser: 10 years of cusf
[19:31] <eroomde> ukhas is already 10
[19:31] <eroomde> well actually no
[19:31] <eroomde> it's younger than cusf
[19:32] <eroomde> uk ballooning is 10 tho
[19:36] <Lunar_Lander> very nice
[19:42] <fsphil> now that I think about it. I don't believe there has ever been a balloon at ukhas-conf
[19:42] <adamgreig> hmmm
[19:42] <adamgreig> i feel like there were some apexhab party balloons at one once
[19:43] <adamgreig> but might be misremembering
[19:49] <richardeoin> adamgreig: if I 'transfer ownership' of the payload while it's over the US, then I think that makes sense
[19:50] <richardeoin> it's way off getting to the US for now though
[19:50] <adamgreig> mm
[19:50] <adamgreig> the US law is quite weird
[19:50] <adamgreig> it used to be the case that only your station was licensed to a callsign
[19:50] <adamgreig> so e.g. if I went to my friend's house I'd be operating as their callsign even though it was me on-air
[19:50] <adamgreig> but I'd have to have a licence myself to be a control operator, and could only operate on the bands and powers of my own licence
[19:50] <adamgreig> that's changed now though
[19:51] <adamgreig> and the rules around automatic unattended telemetry stations are all a bit more... loose?
[19:51] <adamgreig> it's quite permissive about telemetry
[19:51] <richardeoin> that's good for us
[19:51] <adamgreig> even waives the "no encoding meant to render the message unintelligable" bit
[19:51] <adamgreig> sort-of
[19:52] <adamgreig> "Telemetry transmitted by an amateur station on or within 50 km of the Earth's surface is not considered to be codes or ciphers intended to obscure the meaning of communications."

[20:01] <Laurenceb> oh nice feature
[20:01] <richardeoin> from 1052 this morning :)
[20:01] <Laurenceb> I'm wondering if the baro sensor cracked due to low temperatures
[20:02] <richardeoin> yeah the MS5607
[20:02] <richardeoin> I think so
[20:02] <Upu> there is a way to alias the APRS onto the normal
[20:02] <richardeoin> The internal temperature readings from it seem a bit spurious also
[20:02] <richardeoin> I wondered that too Upu
[20:03] <Laurenceb> min temperature is -40C, also it uses silicone rubber encapsulation (i've ripped one apart), and silicone glass transition temp is -50C
[20:04] <Laurenceb> iirc Leo ran a perl script on his pc to grab backlog off aprs and convert to "fake" position uploads
[20:04] <richardeoin> The MS5607 says -35 or so, but the radio was saying -50 something

[21:10] <richardeoin> yeah winds are a little faster at this time of year, but them this flight is a bit lower than Leo
[21:10] <AndyEsser> richardeoin: ah cool
[21:11] <richardeoin> SA6BSS-Mike: it's a multilayer plastic, pa-evoh-pe
[21:11] <richardeoin> 50 micron thickness
[21:11] <SA6BSS-Mike> ok, have to google that :)
[21:11] <SA6BSS-Mike> oki
[21:12] <richardeoin> so it contains layers of polyamide (nylon 6 to be precise), ethylene vinyl alcohol, and polyethene

[21:13] <richardeoin> the polyamide is tough and strong (and possible glassy at these temperatures), the evoh is a very good gas barrier, and

[21:14] <richardeoin> the polyethene has a low enough melting power to make a good seal easily
[21:14] <SA6BSS-Mike> looks to the same as in food vaccum plastics

[21:18] <AndyEsser> woo! hardware timer interrupts are behaving
[21:18] <SA6BSS-Mike> we have those in small sizes at work , allways looked like it could be used, and as you say I figured it would be "easy" to bond/melt together
[21:18] <AndyEsser> time to refactor all my code to use those :)
[21:18] <daveake> Cool, it's the One True Way

[21:19] <AndyEsser> will genericise it another time
[21:19] <AndyEsser> but for now can set up timers for GPS and RTTY transmit
[21:19] <AndyEsser> rather than nasty software timers
[21:19] <AndyEsser> then to play with power saving modes :)
[21:22] ipdove (~ipdove@interclub.plus.com) left irc: Quit: Nettalk6 - www.ntalk.de
[21:26] <AndyEsser> hmm, suppose I should really use hardware timers to trigger each RTTY pulse not just the gaps between messages as well
[21:31] jcoxon (~jcoxon@ joined #highaltitude.
[21:37] <eroomde> ABSOLUTELY
[21:37] <eroomde> you should
[21:38] <eroomde> getting 50-baud with hand-tuned delay loops based on number of instructions is extremel;y unrobust and just really smelly
[21:39] <eroomde> timers+interrupts is The Right Way to do it
[21:39] <AndyEsser> I was using the handy _delay_ms() function the AVR library provides :P
[21:39] <AndyEsser> not counting instruction times
[21:39] IUBAVM (9c3803e6@gateway/web/freenode/ip. joined #highaltitude.
[21:40] <AndyEsser> Which I guess is just someone else has handle the instruction counting ;)
[21:40] <AndyEsser> handled*
[21:40] <eroomde> i assume the length of instructions is short relative to 20ms
[21:40] <eroomde> so you can get away with ignoring it in this applications as the errors aren;t big enough
[21:41] <eroomde> but in general, i'd not architect things in that way
[21:41] <AndyEsser> I ran a _delay_ms(500) through the scope, I'm very impressed with how accurate it is
[21:41] <AndyEsser> but wouldn't want to do it if I need proper precision
[21:41] number10 (568ef30b@gateway/web/freenode/ip. left irc: Quit: Page closed
[21:41] <eroomde> though i totally get it when spitballing and getting something up and running quickly
[21:41] <AndyEsser> the _delay_ms() and _delay_us() stuff is great and simple for prototyping
[21:41] <AndyEsser> and means not having to juggle timers around because you don't have enough
[21:41] <eroomde> yep

[21:46] <Upu> pingf
[21:47] <Upu> lets see a screen shot of what you can see
[21:48] <IUBAVM> what's best way to send?
[21:49] <Upu> upload screen shot to imgur
[21:49] <Upu> so sit rep me : on a Mac, its transmitting
[21:49] <Upu> what do you have running as your SDR ?
[21:50] <IUBAVM> you mean in terms of the SDR dongle that I purchased?
[21:50] <Upu> yeah what software do you have to run that
[21:50] <Upu> I'm not that good on Macs
[21:51] <IUBAVM> http://i.imgur.com/xVkZU3v.png
[21:52] <Upu> that either isn't the signal or it doesn't look right
[21:52] <Upu> Habduino ?
[21:53] <AndyEsser> mac software always looks so much nicer on the eyes
[21:53] <IUBAVM> looking for batman/cat ears, right? Yes, trying to make sure I can get signal form the habduino.
[21:54] <Upu> you got them
[21:54] <Upu> it just looks crap - Habduino ?
[21:54] <daveake> shift is wrong; cursors not aligned
[21:54] <IUBAVM> The signal does occasionally collapse into a single peak
[21:54] <Upu> ok if its Habduino it needs to be set to RTTY 50 baud 7N2
[21:54] <Upu> and the shift needs to be smaller in dl-fldigi
[21:55] <Upu> change these in OpMode -> RTTY -> Custom
[21:55] <IUBAVM> with the carrier shift at 600, right?
[21:56] <Upu> looks like less
[21:56] Lemml_ (~andreas@p3E9C2EAC.dip0.t-ipconnect.de) left irc: Quit: www.adrastea.com
[21:56] <Upu> shift is the distance between those 2 wobbly lines
[21:56] <Upu> I'm going to call thats not that actual signal
[21:56] <Upu> can you zoom out in the radio software ?
[21:57] <Vaizki> gqrx is like jerking off with a cheese grater :(
[21:57] <Upu> thanks for that Vaizki :)

[21:58] <Vaizki> as a Mac user I need to release now and then regarding the state of SDR software...
[21:59] <Upu> get prog to port SDRSharp to the Mac
[21:59] <IUBAVM> http://imgur.com/a/cTp9A
[22:00] <Vaizki> Sdr# is c#
[22:00] <Vaizki> No need to port!
[22:00] <Upu> Settings not correct IUBAVM
[22:00] <Upu> Needs to be RTTY 50 7N2 with a 420 ish shift
[22:00] <Upu> then we'll go work out where you signal actually is
[22:02] <IUBAVM> ok, made that change.
[22:02] <Upu> now zoom out in whatever that radio software is
[22:03] <Upu> I don't think you're zoomed in on the signal
[22:03] <IUBAVM> ok

[22:10] <AndyEsser> heh - going through some boxes trying to find my old maths textbooks - and came across these
[22:10] <AndyEsser> http://imgur.com/cVFWDTI
[22:10] <IUBAVM> not sure what other signal to zoom in on
[22:11] <russss> https://www.youtube.com/watch?v=07Pm8ZY0XJI
[22:14] <IUBAVM> would it help if someone sent me what the signal is supposed to look like and sound like?
[22:15] <Geoff-G8DHE_> These are a couple of signals being shown http://360.g8dhe.net/hab_flights/2015_Flights/index.php?ind=1
[22:17] <Geoff-G8DHE_> Sounds like this http://tenbus.co.uk/icaruscapture_30secs.mp3
[22:18] <Geoff-G8DHE_> Not convinced that you weren't on the signal before but the display in the SDR program was lacking in resolution
[22:19] <Geoff-G8DHE_> The audio signal looked about right in the lower right corner.
[22:19] <IUBAVM> ok, that's really helpful. as I've definitely heard that signal before.....
[22:20] <Geoff-G8DHE_> There is normally a pnel for changing the FFT display in the SDR program, the defaults are usually quite low giving you that blocky result
[22:21] <Geoff-G8DHE_> Making the resolution to fine however takes a lot more processing power!
[22:22] <Upu> just doesn't look like the proper signal
[22:27] <Geoff-G8DHE_> Also the audio level to dl-fldigi was quite low, adequate but only just.
[22:29] <Upu> he's had to go pick his son up
