[06:33] <f5vnf> morning
[06:33] <eroomde> salut f5vnf
[06:36] <f5vnf> bonjour , are there any flights expected my way this weekend
[06:36] <eroomde> i don't think so in theory - just normal up/down latex flights
[06:36] <eroomde> although
[06:36] <eroomde> 1) up/down latex flights frequently have other ideas
[06:37] <eroomde> 2) Leo announces his flights by people receiving telemetry from them
[06:38] <f5vnf> it was b11 /12 that got me into this tracking , somebody mentioned them and i was fascinated, been watching and learning eversince

[06:42] <eroomde> ah yes

[06:46] <Mik_WD8MNV> might be able to use somethig like ardupilot
[06:47] <eroomde> indeed
[06:49] <Upu> f5vnf I think there is a launch today possibly

[07:00] <Upu> ok f5vnf, currently nothing that way but Leo does launch usually on a Friday
[07:01] <Upu> fsphil is launching a Latex floater which will be much higher and may be recievable
[07:01] <Upu> on Sat I think
[07:01] <Upu> launch is from northern Ireland
[07:03] <f5vnf> thanks for info will watch and wait.

[07:06] <eroomde> sorry got confused
[07:07] <eroomde> cool it's going to alaska
[07:07] <fsphil> the predictor doesn't like multi-day predictions, not telling me how long a flight that is :)
[07:08] <x-f> 13 hours
[07:08] <fsphil> + some days
[07:08] <fsphil> possibly 6
[07:09] <x-f> someday we'll get there

[09:17] <GMT> Hello Ugi, nice pics from your weekend flight
[09:19] <Ugi> Thanks GMT - yes, we were pretty happy with those - we were lucky with the weather
[09:20] <Ugi> Nice set of data from the sensors too - and amazingly between us all we didn't miss a single string of the transmission during the flight!
[09:20] <Ugi> impressive, I thought!
[09:20] <GMT> it seemed to be a good strong signal from here (W London), very stable
[09:21] <Ugi> Glad to hear that - I'm sure it drifted a bit, not least because it was quite hot in the box before we got it into the air - it was 40'C in there
[09:22] <Ugi> However, it was received at amazing distances - 125 strings from 600 km away
[09:22] <Ugi> I was impressed with that
[09:22] <Ugi> I think my copper-tape 1/4 wave GP seems to have worked pretty well
[09:23] <GMT> you were lucky with the weather too ... it stayed very close to your launch site
[09:24] <Ugi> Yes, we had been struggling with the weather for weeks but when it finally came around, I gave us a really good flight.
[09:25] <Ugi> we had plenty of time to pack up and take a strategic position for landing
[09:25] Penfold (~mike@194.75.60.69) left irc: Ping timeout: 260 seconds
[09:26] <GMT> the car-tracker seemed to be slow to update, so we didn't know where you were
[09:27] <Ugi> Yes, it only relayed a new position when I turned the tracker off and back on but I was using my phone to navigate so I couldn't do that too often
[09:27] <GMT> ah, okay, that makes sense then

[09:30] <Ugi> The spots we could find to stop were allways the ones with no 3G!
[09:32] <GMT> we have it so good and easy in London, I forget how patchy the sigs are out in the countryside
[09:32] Penfold (~mike@194.75.60.69) joined #highaltitude.
[09:35] <Ugi> Yes, it was fine overall but constant 3G would have made things a lot smoother
[09:40] <SpeedEvil> Ugi: though somewhat harder to move in.

[09:41] <Ugi> Good morning G4AIU-Eugene
[09:42] <G4AIU-Eugene> Ugi GM is WGGS1 running today?
[09:43] <GMT> I'm assuming WGGS1 is still flying, but not heard anything from them
[09:44] <Ugi> I'm afraid to say I don't know - I have nothing on the tracker ATM save for the flight listing
[09:45] <G8KNN> They were en route to launch site at 9.14 this morning
[09:45] <G4AIU-Eugene> GMT I saw the info on WGGS1 up until last night but it seems to have gone. Very new to all this - but enjoying it so far!
[09:46] <GMT> WGGS1 on the map y'day was it being tested in Wirral, launch is due from Welshpool, so we will have to wait for it to appear
[09:48] <G4AIU-Eugene> OK - many thanks - will check later
[09:51] <G0TDJ_Steve> Ping GMT Sorry, I went out early this morning, Wassup?

[09:56] <la3eq> there is no balloon on the map!
[09:56] <G0TDJ_Steve> No, sadly not yet.Would you be interested?
[09:57] <mfa298> it could be they have limited 3g access there so it might not appear until someone has heard it in the air.

[10:20] <daveake> pico*

[10:21] <craag> I would, but unfortunately I'm launching in yorkshire the following weekend, so I'm going to spending enough time on hab-stuffs as it is!

[10:26] <db_g6gzh> morning all
[10:26] <chrisstubbs> the "disposable 50" is 0.46m^3 iirc
[10:27] <G0TDJ_Steve> daveake: I'd prefer a 'flight' with a resolution so the Scouts see the whole process
[10:27] <G0TDJ_Steve> chrisstubbs: Again in English :D
[10:27] <G0TDJ_Steve> Oh, almost half a meter cubed?
[10:28] <craag> G0TDJ_Steve: In my experience the foils tend to ascend at about (free lift in g)/10 m/s
[10:28] <craag> I tended to aim for 1.2-1.5m/s ascent rate
[10:29] Action: G0TDJ_Steve is taking notes
[10:29] <craag> So about 15g of free lift for a definite recovery.
[10:29] <craag> Can get away with 12g, but I wouldn't go less than that.

[10:38] <Babs> Hix - so waterjetting apparently has issues with drill holes and the CF fraying?
[10:41] <fsphil> we should put a little propeller on the foil balloons, to maintain altitude
[10:41] <fsphil> during the day use solar to drive it, keep the altitude from getting too high

[10:42] <fsphil> basically
[10:42] <eroomde> Babs, yes it does
[10:43] <eroomde> it's a pig on composites
[10:43] <eroomde> high speed burring is sort of the only thing that seems to work well
[10:43] <eroomde> or if you do waterjet, consider gluing metal washers either side of the cut hole so it can keep its strength
[10:45] <Laurenceb_> otherwise it delaminates?
[10:45] <Babs> morning eroomde
[10:45] <eroomde> morning
[10:45] <eroomde> Laurenceb, yes
[10:46] <eroomde> end-on they're not very strong or wear-proof
[10:46] <Hix> hmm Babs yeah, for small holes, drilling is better. i beleive they can control edge delamination well enough though
[10:46] <Hix> have you asked them about a sample part they have cut
[10:47] <Babs> I have a CNC machining option, Hix and I were discussing whether it was cheaper or not to go down the water jet route
[10:47] <Babs> Hix - they have some nice wing spars on the site which in look and feel looks like what I am going for
[10:47] <Babs> with a few drill holes
[10:47] <Hix> based on the CNC cutting speeds I'd say it could add up quickly. did you give any thought to the hand layup idea
[10:47] <Babs> difference is I have many many drill holes
[10:48] <Hix> do you need so many holes? bonding could be a lot easier
[10:48] <eroomde> in holes for CF rocket tubes we've always resealed any drilled holes with epoxy around the edges
[10:48] <Babs> I have the option of emailing them both with the file and getting quotes, so we will see where we get to
[10:48] <eroomde> i.e. we paint a thin layer of epoxy around the hole edge
[10:48] <Hix> taping the laminate can help too
[10:49] <Hix> though proper carbon cutting tools are fortunes
[10:50] <Babs> Hix - I have made the mistake of trying to make it as light as possible, so it looks very sparry and drilly. Not keen on gluing it (in particular because it needs to be adjustable to get the camera properly balanced within the gimbal)
[10:50] <eroomde> http://oi53.tinypic.com/2d8nfc6.jpg
[10:50] <eroomde> metal collars to line the hole as in b)
[10:51] <Babs> its only 2mm carbon and they are straight cuts (rather than, for example, getting it down to 1mm over a large area) so hopefully the cutting and drilling should be the primary task, rather than burring away large areas
[10:51] <Babs> thanks eroomde

[11:36] <craag> mfa298: Although you're quite well placed in the country for this one!
[11:36] <mfa298> the email suggested it's only a 5mW tx so lower power and more path loss might make it harder to hear

[12:09] <mikestir-wggs> the 869 antenna is rubbish

[12:10] <mikestir-wggs> there's a page of altitude records on there somewhere
[12:11] <Martin_G4FUI> Anyone using and SDR with HDSDR out there - I suggest using CW mode and enabling CWAFC - I've used this a for the last two flights and it's able to lock onto the signal nicely for "hands free" tracking :)
[12:11] <g8zbj> mikestir-wggs: may be my end drifting? 2 receivers and one seems a few kHz out. Must calibrate them properly.
[12:12] <mikestir-wggs> it has drifted slightly
[12:12] <G0TDJ_Steve> Nothing received here in Crayford but there is a large hill in the way.... I'll let you know if I get anything

[12:13] <Hix> oh wow - never knew a fighter had gone to them alts
[12:13] <mikestir-wggs> not bad actually because I don't think the antenna on the car will work that well on 868
[12:13] <Martin_G4FUI> The AFC in HDSDR makes the waterfall look very wobbly, but the decoder manages to track it OK

[12:32] <GMT> I can *just about* hear rtty on 869.8 in London, not bad for 5mW and 225 kms
[12:32] <gonzo_> I find that the filters should be a min of 1.5 times the baudrate
[12:32] <GMT> no antenna for 868, just using dual-band 2m/70cms vertical
[12:33] <gonzo_> narrow they will see less noise, so better snr, wider they will follow a drifty signal better

[12:33] <mattbrejza> why the AFC and rx filter are combined im really not too sure though

[12:36] <gonzo_> it relies on the data cioming through the mark/space filters

[12:42] <Upu> 5mW ?
[12:42] <Upu> in that case it is impressive
[12:42] <Upu> wobbly signal
[12:42] <Upu> but decodable
[12:43] <Upu> that said
[12:43] <Upu> its 100km from me
[12:43] <mikestir-wggs> Upu: 869 is 5mW on a dipole
[12:43] <mikestir-wggs> on the side of the payload, above the main antenna
[12:43] <GMT> I can hear the 869.8 sig in London, but not decode
[12:43] <Upu> not far
[12:43] <Upu> decoding fine mikestir-wggs
[12:43] <Upu> on a scanner sat in the window
[12:43] <mikestir-wggs> nice
[12:44] <craag> Hmm, maybe 868 could be used for circ-polarised downwards link to chase car.
[12:44] <craag> Would be a nice small antenna
[12:44] <mikestir-wggs> seems weaker here but we're almost directly underneath and the antenna on the car is for 70cm
[12:44] <fsphil> weird, nice signal on 434 mhz but no decode at all
[12:44] <fsphil> definitly 7n2?
[12:44] <mikestir-wggs> I have the second vfo set to it though and flicking over occasionally
[12:45] <mikestir-wggs> fsphil: yes
[12:45] <M6GTG_nerdsville> signal here on 869 seems to have dropped in strengfth, assuming a null in antenna
[12:45] <mfa298> woohoo, looks like it might have got high enough to clear the hill to the north of here, the 434 signal looks to be much stronger now
[12:45] <craag> fsphil: rv?
[12:45] <fsphil> tried that craag, no diff
[12:46] <craag> pulseaudio?
[12:46] <db_g6gzh> fsphil: gqrx and pulseaudio?
[12:46] <fsphil> it doesn't seem to be this time
[12:46] <craag> snap
[12:46] <fsphil> when pa/gqrx messes up, the waterfall spins past really quickly
[12:46] <fsphil> it's looking normal
[12:46] <M6GTG_nerdsville> the 434 wasn't proving much of a challenge, so switched to the 869 ;-)
[12:46] <db_g6gzh> if so, try enabling and disabling the dsp in gqrx
[12:47] <db_g6gzh> I sometimes got a short period of good decodes after doing that
[12:47] <db_g6gzh> but I never fixed it to work reliably

[12:49] <fsphil> disabled restarted both gqrx and fldigi
[12:49] <fsphil> no change

[12:50] <fsphil> bizzare
[12:50] <fsphil> it looks fine on the waterfall
[12:50] <db_g6gzh> I've definitely had it look fine but not decode
[12:50] <mattbrejza> tried my decoder fsphil ?

[16:04] <mikestir-wggs> the mobile tracker seemed to be behaving slightly less odd so we just used that at the end
[16:07] <Babs> question on standing waves. I know that the antenna wire needs to extend 140 or so mm out of the bottom of the coax shielding, but my question is, if it is difficult to thread coax through a hab, can i run a standard wire from the transmitter to the location of where i want the antenna to start
[16:07] <Babs> then connect a bit of coax, then run a 140mm wire after that to generate the required standing wave to transmit correctly?
[16:08] <Babs> (I know that there will be power loss through the bit of unshielded wire ahead of the coax)
[16:08] <Babs> which is not ideal, just looking for a work around

[16:11] mikestir-wggs (~quassel@149.254.180.115) left irc: Ping timeout: 260 seconds
[16:12] <Babs> because the antenna will run out of the bottom of this http://imgur.com/7oLY26d ideally, and all of the wiring runs through slip rings (to enable continuous rotation of the gimbal without wires tangling), and coax isn't compatible with the slip rings

[16:14] <Babs> good option mattbrejza. I'm trying to limit the amount of weight in the turny bit because it increases the torque that i need to apply to get it moving BUT an NTX-2 is light and fairly easy to do. Will have to count up that I have enough wires to do it.
[16:15] <G0TDJ_Steve> Nice solution mattbrejza
[16:15] <Babs> it will be interesting to fly it in level mode to see whether the quality of the signal is any better than one where the antenna is swinging like a pendulum
[16:15] <mattbrejza> only needs one more wire i think
[16:16] <Babs> the NTX-2 has a few connections no? (I don't have my tracker with me here). Power in, ground, toggler etc.

[16:16] <mattbrejza> well you can borrow power from the imu?
[16:17] <mattbrejza> then just need one wire for the telem, then have the resistor network on the turny bit (reduces transmitted noise)
[16:18] <Babs> you can, I'm trying to keep it all on separate circuits and batteries so if one goes down, everything doesn't go down but its certainly an option. good plan.

[16:19] <LazyLeopard> Ugh. You probably want to establish control of it... :/
[16:19] <Babs> I am not sure that the wiring will cope with the current going through them from the onboard motors, so I may need to double up on that too. But I have two slips rings, 1 with 12 and 1 with 24 wires to play with so there should be a solution somewhere in all that. thanks mattbrejza, good tips

[18:36] <tjanos> Anyway, these TLEs should agree with the numerically propagated orbits to 1-2 km over the next 24 hours and there should be enough separation between the payloads to distinguish which is which. Good luck!

[18:52] <PE0SAT> mfa298: Thx
[18:53] <tjanos> Ok, this is the actual situation what we would like to see more clear
[18:53] <GMT> well, in the absence of any HABs it just about fits into the 'high altitude projects' area
[18:53] <mfa298> I'm not really the person to say yes or no but I suspect the general consesus would be that there's no realy problem talking about higher altitudes than we are normally used to
[18:53] <tjanos> after the Falcon 9 launch
[18:56] <PE0SAT> The fact that there are so many object after the falcon launch makes it even more difficult to find the right combination

[18:57] <roshni> hi guys, where do i get the permission to launch a weather balloon?
[18:57] <GMT> which country?
[18:58] <roshni> UK
[18:58] <roshni> england
[18:58] <GMT> if it's a latex huge balloon you will need a NOTAM so contact the CAA (see UKHAS wiki); if it's a small 'pico' balloon (< 2m) then no NOTAM required
[18:59] RocketBoy (~steverand@05464b63.skybroadband.com) joined #highaltitude.
[18:59] <mfa298> note that the <2m is for balloon + payload for the entire flight (so very few balloons fit into that requirement)
[18:59] <tjanos> PE0SAT: I wasnot at the keyboard, but I see, some hours ago you received something from DANDE? is it rtue?
[19:00] <PE0SAT> tjanos: Yes 10 frames decoded
[19:00] <roshni> when should i get/apply the permission? a month?
[19:01] <mfa298> roshni: what are you planning on launching and where from and how were you thinking of tracking it ?
[19:01] <fsphil> roshni: there's a bit about it here: http://ukhas.org.uk/general:beginners_guide_to_high_altitude_ballooning
[19:01] <PE0SAT> tjanos: http://www.pe0sat.vgnet.nl/ for more information
[19:01] <fsphil> and http://ukhas.org.uk/general:restrictions_legality
[19:01] <fsphil> basically you need to apply 28 days in advance of the launch
[19:01] <fsphil> at least 28 days*
[19:02] <PE0SAT> tjanos: Next pass over europe in 8 minutes
[19:02] <mfa298> unless you're fsphil, then try 6 months and hope/pray ;)
[19:02] <fsphil> indeed
[19:03] <tjanos> PE0SAT: thanks! Its great!

[19:03] <Upu> evening
[19:04] <roshni> by the way i am totally new to all this and i was wondering around how much it will cost?
[19:04] <fsphil> I've still not heard back about saturdays's lanuch
[19:04] <fsphil> and there's nothing on notaminfo
[19:04] <GMT> why does phil have problems with NOTAMs, his location?
[19:04] <fsphil> doesn't seem to be location
[19:05] <fsphil> they just seem to ignore them :)
[19:05] <fsphil> the requests*
[19:05] <GMT> oh, okay.
[19:05] <fsphil> it's not just me, the CAA can be very unresponsive
[19:06] <daveake> Can't be Arsed At all
[19:06] <mfa298> roshni: it can vary a lot depending on what you're launching and what you want it to do, heavier payloads going high will generally need more Gas and potentially a bigger balloon making it more expensive, light payloads can be done quite cheaply.
[19:07] <fsphil> the helium will likely be the most expensive part
[19:07] <roshni> can you share any of your experience doing similar projects?
[19:07] <fsphil> it's a lot of fun :)
[19:08] <fsphil> and quite stressful ;)
[19:09] <number10> always wondered what that TLA was daveake
[19:09] <mfa298> roshni: it's worth reading the beginners guide link fsphil posted just now and have a browse of the wiki

[19:11] <GMT> PE0SAT: best to listen for DANDE in narrow FM or USB?
[19:12] <roshni> what sort of weather is the best for launch?
[19:12] <fsphil> calm and sunny
[19:12] <Upu> http://www.youtube.com/watch?v=ZzHug3Ji3Ms&feature=c4-overview&list=UUGkq3Q2JQhN_ChjcPPwAW3A
[19:12] <Upu> this is perfect
[19:12] <fsphil> wind, or even a gentle breeze, can make it difficult to measure the lift of the balloon
[19:13] <daveake> wind can be an issue, but rain/snow/cold are just annoying
[19:14] <Upu> cold is annoying when tying knots
[19:15] <fsphil> and typing on keyboards
[19:15] <Upu> rain is just annoying because its wet
[19:15] <Upu> however my advice is just take a daveake
[19:15] <x-f> i see DANDE on the waterfall every 15 seconds, no idea how to decode it though
[19:15] <mfa298> unless you're trying to float a pico when the rain might cancel your free lift.
[19:16] <fsphil> that the satellite?
[19:16] <Upu> record it x-f
[19:16] <fsphil> x-f: ^?
[19:16] <x-f> yea
[19:16] <x-f> it's above your horizon too
[19:16] <fsphil> 9600 FSK seems to be a right pain
[19:16] <fsphil> what frequency?
[19:16] <x-f> 436.75
[19:17] <x-f> [14:49] <PE0SAT> 436.75 MHz FM 9600 baud FSK

[19:18] <Upu> nothing heard here on the colinear
[19:18] <fsphil> oh yea
[19:18] <Upu> what do you use to decode it ?
[19:18] <fsphil> got it
[19:18] <fsphil> I've nothing to decode it either
[19:18] <fsphil> soundmodem should do it
[19:18] <Mik_WD8MNV> is it packet?
[19:18] <GMT> I can possibly hear it in the noise, but not a good pass for me; next one at about 10pm is 71 degrees
[19:19] <fsphil> 9600 packet Mik_WD8MNV
[19:19] <fsphil> wait it's stopped here
[19:19] <fsphil> yea gone

[19:19] <fsphil> ah, saw a weak one
[19:19] <fsphil> er, and another
[19:19] <fsphil> it's hoping frequencies

[19:22] <mfa298> roshni: read through this, it's what most people do http://ukhas.org.uk/guides:tracking_guide
[19:23] <ibanezmatt13> generally when you're reading GPS data from the serial, what's the function used most commonly to read it in C?
[19:23] <GMT> Upu: on Celestrak select 'current data' and then 'last 30 days launches'
[19:23] <mfa298> ibanezmatt13: my first hint is don't use strtok - it looks like it might be good but isn't

[19:29] <GMT> to decode DANDE speak with PE0SAT/Jan; it's 9600 baud FSK packet

[20:50] <eroomde> the joy and challenge of maths is that different people find different aspects more obvious and less obvious
[20:50] <eroomde> so its quite normal for some bits to just not make sense

[20:56] <Lunar_Lander> eroomde, yeah a radio host should know what he/she is playing!
[20:56] <Lunar_Lander> also, is noble again saying "engineering saves mankind"?
[20:57] <eroomde> dunno
