[11:20] <Willienl> was checking for baloons example national weather released one a hour ago but think someone is jamming the signal :S
[11:20] <Willienl> at 403,200 MHz a 5KHz wide signal sounds like tx without modulation :(
[11:21] <fsphil> it's unusual to get noise around those frequencies
[11:21] <fsphil> it could be something local?
[11:21] <Willienl> well we have a new radar thingy at the haven here :S
[11:22] <fsphil> still would be surprised if they broadcast over the sondes frequences, they're an international standard
[11:22] <Willienl> and every time i try to receive 70cm amateurs or 2 meter band i receive blank signals without modulation just silent at -20~-30 dB
[11:22] <Willienl> fsphil: well ever seen a radar thing rotate like a wind mill ?
[11:23] <fsphil> urg, could be overloading your receiver
[11:23] <fsphil> you might need a filter
[11:23] <Willienl> i dunno what it is but they transmit grids about 1MHz wide with spikes at -25dB at 1 km distance :S
[11:23] <Willienl> fsphil: yes local pager networks and other stuff overload my receiver rtl_sdr with fitipower fc0013 tuner chip thats over sensitive on a telescope whip antenna :(
[11:24] <fsphil> all the sdr dongles are not good at handling loud RF sources
[11:24] <Willienl> still unsure how to filter this on a 50~900MHz receiver :(
[11:24] <fsphil> mine is deaf without filtering
[11:24] <Willienl> no you can adjust the gain down to -60dB :)
[11:24] <Willienl> instaid f +60dB amplify noise
[11:24] <fsphil> bbl
[11:25] <Willienl> ok havefun

[11:38] <Hix> UKHAS, can you use EEPROM to write to saving SD coming loose etc?
[11:38] <Darkside> eeprom not big enough
[11:38] <Darkside> not on most AVRs anyway
[11:38] <natrium42> solde the sd :)
[11:39] <natrium42> +r
[11:39] <Hix> a separate chip
[11:39] <Hix> sodder ;p
[11:39] <Darkside> Hix: sure, but a sd card is basically a big eeprom :-)
[11:39] <jonsowman> FRAM perhaps
[11:39] <Hix> just thinking it could come loose and a chip is tiny so could be on a small board
[11:39] <Darkside> sure
[11:39] <Darkside> you can get really big flash chips
[11:40] <Darkside> and you could do that
[11:40] <Darkside> then you'd need a bit of code to dump the data, but thats easy too
[11:40] <Darkside> i did that once, had a 32mbit flash chip
[11:40] <Darkside> never ended up using it
[11:41] <Darkside> micronut v1 has a space for one
[11:41] <Hix> worth looking at though. might play with the idea whaen i can actually code :)
[11:41] <Darkside> but yeah, never used
[11:41] <Darkside> mm
[11:41] <Darkside> sd cards are pretty reliable
[11:41] <Darkside> takes a lot of force to knock out a microsd card
[11:41] <Darkside> they lock in really well
[11:41] <Hix> spose hot glue would be good enough
[11:41] <Darkside> you dont want that tho
[11:41] <Darkside> you want to get it out after
[11:41] <Hix> only a wee blob
[11:42] <Darkside> mm
[11:42] <Hix> comes off with scalpel easily enough
[11:42] <Darkside> but still, uSD card holders are really string
[11:42] <Darkside> strong
[11:42] <Darkside> just check the code, so it doesn't break if the card does come loose! :D

[12:34] <nosebleedkt> hi
[12:34] <Hix> hi nosebleedkt
[12:35] <nosebleedkt> i have a question!
[12:35] <nosebleedkt> like always
[12:35] <nosebleedkt> the GSM antenna
[12:35] <nosebleedkt> has that black cover on it
[12:35] <nosebleedkt> but the real antenna is a wire inside
[12:36] <nosebleedkt> does this black rubber thing has any effect on the signal?
[12:36] <nosebleedkt> Im thinking of removing it
[12:36] <KT5TK> Just a minor effect.
[12:36] <KT5TK> Try it. If it works, it's ok
[12:36] <DrLuke> Not an expert, but maybe it's what holds the wire together?
[12:37] <KT5TK> It's mainly a mechanical protection
[12:38] <nosebleedkt> ehh
[12:39] <nosebleedkt> I think it does nothing
[12:39] <nosebleedkt> just protecting the wire from real world
[12:40] <nosebleedkt> Randomskk, SpeedEvil
[12:40] <nosebleedkt> any suggestions?
[12:42] <KT5TK> Since air has a different relative dielectric value than plastic, it may have a slight change of the resonance frequency, but Likely this change is minor.

[19:21] <Adam012> Hi, is anyone able to give me a little help tuning fldigi in for the first time? I set up the arduino and nxt2 to transmit, I received the signal just fine on the FT-790 (a slight clicking in the background that was in time with the Arduino led) but I am lost with the fldligi settings.
[19:23] <Hix> dunno if you've seen but http://ukhas.org.uk/guides:linkingarduinotontx2
[19:24] <Hix> probably have though based on what you're saying
[19:24] <Hix> generally though if you right click on the RTTY box bottom left you can change shift etc
[19:25] <Hix> hope that helps
[19:33] <DrLuke> www.bff-hab.de - new domain aquired :)
[19:33] <Lunar_Lander> yay!
[19:34] <Adam012> The box in the bottom left doesnt have a rtty option, its all BPSK-XXX
[19:34] <Hix> got a screengrab?
[19:35] <Adam012> One moment, uploading...
[19:35] <Hix> think most of the community are in the post habfest pub :)
[19:35] <Hix> I am by no means an expert either, but may be able to help
[19:36] <Adam012> http://img.photobucket.com/albums/v167/cazbuh/Settings_zps15e8fa74.png
[19:36] <Hix> right, right-click in that box and you should be able to set bits parity etc
[19:36] <Adam012> I feel a bit lost so any help is glady welcomed!
[19:37] <Hix> BPSK-XXX
[19:37] <Hix> I'm pretty muc permanently lost with most of the code :D
[19:37] <LazyLeopard> ...then you've probably selected BPSK-500 from the Op_Mode menu.
[19:37] <Hix> don't have dl-fldigi on this machine thougfh so all from memorry
[19:37] <Hix> good spelling as usual
[19:37] <Hix> :/
[19:38] <LazyLeopard> Adam012: You're not in --hab mode
[19:38] <Adam012> Ah, selected rtty from opmode
[19:38] <LazyLeopard> Go to Op_Mode drop-down and select RTTY-something
[19:38] <LazyLeopard> ;)
[19:38] <Hix> hab mode just enables online though no?
[19:38] <Adam012> @Hix thats what I understood
[19:38] <Hix> not important for testing
[19:39] <LazyLeopard> Yeah, and changes the layout, but then autoconfigure will select mode etc. for the payload...
[19:39] <Adam012> I'm in Rtty mode but the waterfall does not show two clear lines
[19:39] <Hix> what do you see?
[19:39] <Hix> lots of yellow?
[19:39] <LazyLeopard> Yeah, your screenshot is showing a pretty weak signal.
[19:40] <Hix> tuned in properly on RX?
[19:40] <Hix> play and see
[19:41] <Adam012> The nxt2 is set for 434.075 as is the radio and fldigi, which should I alter?
[19:41] <Hix> radio
[19:46] <Adam012> Tried increasing the radio volume: http://img.photobucket.com/albums/v167/cazbuh/Settings2ndattempt_zps5bcb3d7f.png

[19:58] <Hix> but go back to "3rd try" and click on 2300 with ~350 shift
[19:58] <Hix> theres two faint lines there
[19:58] <Hix> looks promising, if weak
[19:58] <Adam012> carrier shift to 425, baud to 50, 7 bits per character, no parity and 2 stop bits
[19:59] <Adam012> Okay, going back to 3rd settings
[20:00] <Hix> actually shift closer to 300
[20:00] <Hoppo> Hi Hix, you said earlier you were only hearing a faint ticking in time with the LED is that correct?
[20:00] <Hix> adjust nutil the two red lines are spaced as the yellows
[20:00] <Hix> not me dude, Adam012

[20:04] <Hix> hmmm, didnt feel at my best on wakeup
[20:05] <Adam012> Okay, I reduced the shift, tuned down to 434.070 and highlighted the upper end of the waterfall: http://img.photobucket.com/albums/v167/cazbuh/Settings5thattempt_zpse4504be5.png
[20:05] <Hix> Adam012, any better or have you banged your head into the desk in frustration
[20:06] <Hix> hmm that signal does look shite
[20:06] <Hix> waht RX have you got?
[20:06] <Hix> *what
[20:06] <Hoppo> Adam012 something is not right there. If you have the transmitter on your desk next to your receiver you should have a mega strong signal.
[20:06] <Adam012> Head banging at the moment. I wish I understood the settings better on both the FT-790 and fl-digi but I've never used radio for anything other than Radio 1, 2, 3 and 4
[20:06] <Hix> oooh USB orLSB?
[20:07] <Adam012> USB
[20:07] <Adam012> Where can I find the RX figures?
[20:07] <Hix> should be mega strong
[20:07] <Hoppo> When you tuned the radio in you said you heard a clicking is that correct?
[20:08] <Adam012> Yes, there was a LOT of interference so the clicking was very quiet and in the background
[20:09] <Hix> if you remove the line out can you hear RTTY?
[20:09] <Hoppo> Then your transmitter is not working.
[20:09] <Adam012> I hear a buzz and a warble, like the old dial up.
[20:09] <Hoppo> You should be hearing a warble of data. It's very obvious and should jump right out at you.
[20:10] <Adam012> Yup, in time with the led'
[20:10] <Hoppo> no
[20:10] <Hoppo> much faster than the led. 50 times a second in fact.
[20:10] <Hix> :D
[20:11] <Adam012> After a little play I can hear a distinct warble on 434.071
[20:11] <Hix> comme ca http://tenbus.co.uk/icaruscapture_30secs.mp3
[20:11] <Hix> plug it back in and screengrab
[20:12] <Hix> biam smoke time :)
[20:12] <Hoppo> That's what you should be hearing. :)
[20:13] <Hoppo> But it should be even clearer than that if it's on your work bench.
[20:14] <G0DJA> What antenna are you txing into?
[20:14] <G0DJA> even with no antenna it should be *very* loud though

[20:35] <Adam012> Yup
[20:35] <Darkside> ok

[20:35] <Adam012> 434.075 - coming through on 434.068

[20:36] <Hix> it's workkng no?
[20:36] <G0DJA> It's set in either the software, or you could swap the pins on the NTX input round the other way
[20:36] <Hix> upu giude from wiki no?
[20:36] <Darkside> is it using 2 pins on the arduino or just one

[20:58] <DrLuke> Today I got an idea for a cool cutoff system
[20:58] <DrLuke> basically just got glue together 2 loops of string, and also put a resistor in it

[21:17] <navrac_paris> it means if the signal is say 434.000 mhz and youve selected usb you would tune above by 1khz to get the tone at 1khz - however you can also get an image at 433.999 which is reversed
[21:17] <navrac_paris> or youve set lsb instead of usb on the rx

[21:51] <navrac_paris_> isnt that for a 3v3 arduino though?
[21:51] <Hoppo> You need 20k resistor for the 5v I think
[21:52] <Adam012> I don't think so, the guide recommended a 20k resistor for 3.3V
[21:52] <navrac_paris_> maybe not - im an rfm user so not au fait with the ntx

[22:04] <Adam012> Hi Hoppo, any more thoughts>
[22:04] <fsphil> I consider we discuss this more
[22:05] <natrium42> I propose discussing your consideration
[22:05] <Hoppo> IAdam012 don't understand how you can be 8k off frequency.
[22:05] <daveake> I'll consider discussing it, for a considerable consideration
[22:06] number10 (569e1af1@gateway/web/freenode/ip. left irc: Quit: Page closed
[22:06] <fsphil> not bad considering
[22:07] <Adam012> @Hoppo - neither do I, perhaps it's the radio?
[22:07] <daveake> wossup?
[22:08] <Hoppo> What happens if you tune it to 434.075 and change the radio to LSB?
[22:09] <Adam012> I've set up a 5V Arduino with a NXT2 transmitter to test out the Yaesu FT-790R I have on loan and to prove that I can get it all working. The NXT2 is 434.075Mhz but the radio (next to it on my dining room table) is picking it up at 434.067?
[22:09] <fsphil> oh that's prefectly normal
[22:09] <fsphil> it can be +/- 15khz
[22:10] <fsphil> depending on the resistors used, and other factors
[22:10] <fsphil> my 434.650 always seemed to run at 434.670
[22:10] <Hoppo> hi daveake, he's working through the tutorial but can only get a signal on USB if he's 8k off frequency and switched the High Low triggers in the code.
[22:10] <jonsowman> also remember your tune will be off by the audio frequency
[22:11] <jonsowman> so if your carrier is being heard at 2kHz on the waterfall
[22:11] <fsphil> the way we drive the ntx2 is beyond what it was designed for, and frequency error is to be expected
[22:11] <jonsowman> then your radio is tuned 2kHz away from the actual signal
[22:11] <fsphil> also the radio itself will have some error
[22:11] <kokey> gosh I thought no one would be back on irc already
[22:11] <fsphil> all three of my radios are slightly different
[22:12] <Hoppo> so why the need to change the triggers in the code?
[22:13] <fsphil> not sure what you mean by that

[22:14] <daveake> silly batteries
[22:14] <Adam012> Okay, after a lot of fiddling with the radio and changing the code back to the original code from the guide I have a working transmission on LSB at 434.071!
[22:15] <fsphil> it should be USB, but hey :)
[22:15] <jonsowman> Adam012: don't worry about the centre freq being wrong
[22:15] <fsphil> make sure dl-fldigi is set to USB
[22:15] <Adam012> Waterfall shows two clear lines in yellow and red
[22:15] <jonsowman> as long as it's not too near the band edges it doesn't matter
[22:15] <daveake> Tuned wrong side, or 0/1 swapped in code, or fldigi Rv button pressed
[22:16] <daveake> Slough. Bound to lose some undesirables here.
[22:16] <Adam012> When I put the code in the first time I was picking up text but garbled. Pressing RV decoded it. I then changed the code and could get the text without having to press RV.
[22:17] <SpeedEvil> I only knough slough from the work of John betchemen
[22:17] fsphil_london (~phil@ joined #highaltitude.
[22:17] <Hoppo> is USB selected in fldigi?
[22:17] <Adam012> Since then, I've tried lots of different frequencies with the radio set to usb but couldn't get the original code to work.
[22:17] <SpeedEvil> http://www-cdr.stanford.edu/intuition/Slough.html
[22:19] <Adam012> Okay, back in USB on radio and fldigi - receiving at 434.068 just fine.
[22:20] <fsphil_london> nice
[22:20] <daveake> good
[22:20] <fsphil_london> side band can be tricksy
[22:20] <fsphil_london> but it's worth getting it right
[22:21] <daveake> It's easy when the transmitter is close to the receiver to think you're tuned in right but to not be
[22:21] <Adam012> @SpeedEvil - I feel much the same about Milton Keynes.
[22:21] <daveake> What I do is turn the receiver frequency down a notch, and the audio should then go up in frequency. If it goes down then you're not tuned in correctly.

[22:22] <Adam012> If I turn the frequency down a notch on the radio the lines jump up the waterfall (to the right)

[22:31] <Darkside> Adam012: thats how it should be
[22:32] <Adam012> Fantastic, it seems that everything is now sorted out. Thanks to everyone who has pitched in with advice and thoughts! I'm going to get to bed now, next step is receiving GPS.
[22:33] <SpeedEvil> :-)
[22:34] <Upu_London> hey fsphil home safe ?
[22:35] <Adam012> Good night all!
[22:35] <griffonbot> @daveake: Thanks to James and Anthony for organising the #UKHAS conference, to all the other speakers for their talks, and to everyone who came along. [http://twitter.com/daveake/status/249638061632286720]
[22:37] <daveake> Reading done. The train is much lighter now; maybe it will speed up
[22:37] <Darkside> heh
[22:38] <Darkside> mine was slow
[22:38] <Darkside> or it seemed slow

[22:40] <Lunar_Lander> daveake, the insurance in germany question is solved I think
[22:40] <fsphil_london> Upu_London, aye! back in one piece
[22:41] <eroomde> on coach
[22:41] <fsphil_london> gonna have a nice lazy day tomorrow
[22:41] <eroomde> after 2nd dinner in chinatown
[22:41] <eroomde> yes me too
[22:41] <eroomde> dr who, thick of it, toast
[22:41] <fsphil_london> definitely toast
[22:42] <fsphil_london> then maybe science museam

[22:42] <Darkside> so science museum
[22:42] <Darkside> do*
[22:43] <daveake> LL How is it solved? You're relying on the law changing before you launch?
[22:43] <fsphil_london> Europe being overthrown my the moon people?
[22:44] <daveake> Upu_London I'll email fsphil's pal DM on Monday
[22:44] <daveake> See if I can get permission for next weekend
[22:44] <daveake> All being well I'll order the gas on Wednesday
[22:44] <fsphil_london> I should go visit him
[22:44] <Lunar_Lander> daveake, mclane showed me an insurer who covers it

[22:55] <jcoxon> hey
[22:56] <jcoxon> on the bus?
[22:56] <Darkside> hey jcoxon
[22:56] <Darkside> we should organise regularish google+ hangouts or something
[22:56] <Darkside> that we can get multiple people on
[22:56] <eroomde> jcoxon: yes
[22:56] <eroomde> shepards bush
[22:58] <Lunar_Lander> yeah I had that idea and Darkside liked it
[22:59] <Darkside> yup
[22:59] <natrium42> sweet conference, i stayed up till 5am to watch it
[22:59] <Darkside> lol
[23:00] <natrium42> :)
[23:00] <Lunar_Lander> :)
[23:00] <natrium42> then fell asleep, too tired
[23:00] <fsphil_london> was good, although now I have to add unit tests to all my code :)
[23:01] <natrium42> did dan fly over for it?
[23:01] <natrium42> i missed his talk
[23:03] <fsphil_london> not specifically for this
[23:03] <fsphil_london> just good timing I think
[23:04] <fsphil_london> worked out well, dan's just arrived and mark's just leaving
[23:04] <natrium42> cool :)
