[01:42] <schofieldau> would it be easier for me to collect it from you if you're around the city at any point?
[01:42] <Darkside> going into the post office, finding a box that looks like it'll hold it
[01:42] <Darkside> hah, i'm always in teh city
[01:42] <Darkside> well, almost always
[01:42] <Darkside> i'm a postgrad at the university of adelaide

[01:43] <Darkside> so yeah, if you could meet me in teh city sometime that woudl be easier
[01:43] <schofieldau> but that'll calm down at the end of this month

[09:18] <UpuWork> 1.21 Gigawatts even
[09:19] <fsphil> you know something has gone wrong if your tracking my payload and it points down

[10:05] <number10> mind you things about the language I dont like already is that it relies on white space indentation

[10:05] <number10> stick some { in there and I would be happier

[10:06] <daveake> Can you #define { as space? ;)
[10:06] <number10> never did occam - did a little parallel C once

[11:15] <costyn_> Elmar_PD3EM: nice!
[11:15] <costyn_> Elmar_PD3EM: which arduino are you using?
[11:16] <Elmar_PD3EM> I have a Uno v3 and a pro mini 328
[11:17] <navrac> daveake - had to dissapear last night - but just to confirm you are right - the ncp1402 doesnt regulate - a component on the pcb was clamping the 3.3v and the drop was in the ribbon cable from the ncp to the board. Also the ncp1402 hasnt enough guts to let the gps get lock on its own with a single AAA - I started mine with an external 3.3 supply and then when it has lock its fine
[11:17] <daveake> "drop was in the ribbon cable" - ouch!
[11:18] <navrac> well there was a good 18" of it and it wasnt for long
[11:18] <daveake> :)
[11:19] <daveake> Also, 2 x Lithium Energizer is about 3.65V open circuit, and very quickly drops to about 3.3V under load
[11:19] <daveake> So I doubt the current through that clamp was very high
[11:20] <navrac> i know there is a way to get the rfm22 to switch off then on again to tx without that initial drift as at one point i got it to be solid - but for the life of me i cant remember how i did it, i was experimenting with power settings at the time
[11:20] <daveake> I assumed the drift was thermal
[11:20] <navrac> certainly a lower power output helps
[11:20] <daveake> yep
[11:21] <navrac> i thought so too - but surely the drift is going to be from the crystal - which is running all the time
[11:21] GW8RAK (~chatzilla@host109-155-70-39.range109-155.btcentralplus.com) joined #highaltitude.
[11:21] <daveake> Yes, but it'll get warmed up by the transmitter
[11:22] <daveake> I don't know - this was just my assumption
[11:22] <navrac> as the smallest change that can be made in the pll is 156hz so it has to be the xtal - but its too far away from the ic to be doing it
[11:22] <navrac> i'm wondering if its supply related?
[11:23] <daveake> Well I had mine running from a 300mA regulator on the Arduino, and it drifted then too. It stablizes after a while (if on coninuously) as you know.
[11:23] <daveake> I tested with a 1400 yesterday (baby version of the 1400, 100mA max), with 2 x AAA at -18C in the freezer, driving an Arduino Mini Pro + RFM22B @ 8mW + uBlox Max6. Got just under 5 hours out of it. I've removed the 1400 and replaced with a 1402 and I'll try again today.
[11:24] <daveake> "baby version of the 1402" I mean
[11:24] <navrac> i think im changing to the 711 regulator as my eyesight cant cope with the 1402's too small and fiddly to solder!
[11:24] <daveake> The current causes the 1400 to drop out at a fairly high battery voltage (1.8V)
[11:25] <daveake> Yeah, the 1402 was fiddly!
[11:26] <navrac> i think the 02 is more efficient from memory so that should help - and i imagine the ublox hadn't got lock so it was probably draining quite heavily
[11:26] <eroomde> the ublox's are very sensitive to psu ripple
[11:26] <eroomde> especially when aquiring
[11:26] <eroomde> if that means anything
[11:27] <navrac> uint8_t setNav2[] = {0xB5, 0x62, 0x06, 0x11, 0x02,0x00, 0x08, 0x04,0x25, 0x95}; sendUBX(setNav2, sizeof(setNav2)/sizeof(uint8_t));
[11:28] <navrac> i used in ozzies code to set power saving on the ublox - cant remember what mode it was tho
[11:30] <Darkside> hey all
[11:30] <navrac> i was running a tx power of 11dBm but had a 5 second receive gap every 30secs - but it was still consuming 18mA on RX

[11:47] <fsphil> that'll do nicely
[11:47] <Darkside> and using sma connectors on the payload
[11:47] <Darkside> since this thing is going to get built into the payload box, it has to be disconnectable

[12:43] <navrac> are you near you rfm22b
[12:43] <daveake> Several :)
[12:43] <kokey> f-call is better than f-all
[12:44] <navrac> i think if you do an spi read on register 7h and then or it with 02h and stick it back it may stop the drift
[12:44] <daveake> ooer. What does that bit turn ofn or off?
[12:44] <daveake> or on even
[12:45] <navrac> it looks like in the libs they havent bothered to change the register to leave the pll running when its not txing
[12:45] <daveake> OIC
[12:45] <daveake> I don't switch Tx off
[12:45] <navrac> ah ok - fair enough then
[12:46] <navrac> but if you wanted to when reading the temp sense and waiting for the info from the gps it would save you a bit of power :-)
[12:46] <daveake> So far I've not done any receving. I have a timer int doing the rtty, then when it gets to the end of a sentence it sets a flag for the main loop to build the next sentence. During that (short) delay the Tx stays on at a mark (or space, whichever it is at the end of a byte)
[12:47] <navrac> gotya.
[12:47] <daveake> But I've saved that snippet for later, cheers :)
[12:47] <navrac> nprob - bored at work so reading datasheets :-)
[12:48] <daveake> wow. You are bored :)
[12:48] <daveake> btw why the slim-jim antenna? Some advantages?
[12:49] <navrac> it was a jpole not a slim jim
[12:49] <daveake> Certainly worked well
[12:49] <daveake> Oh OK (showing my lack of radio antenna knowledge here)
[12:50] <navrac> yes - the quarter wave really needs a solid ground plane whatever people say - I worked for racal designing antennas for tanks years ago and spent 6 months modelling quarter waves
[12:50] <navrac> what i learnt was quarter waves never work as well as people think.
[12:51] <daveake> I can see that for smaller payloads it saves having the radials sticking out
[12:51] <navrac> the jpole gets bad press because people keep feeding it with coax and the screen of the coax actually mucks it up.
[12:52] <daveake> Not a problem if it's wired straight to the transmitter
[12:52] <navrac> but if you solder the rfm directly to the tap point on a jpole it is balanced
[12:53] <navrac> and in my tests in spain which were from a 10 story building with the aerial hanging out the window on a broom and then i walked half a mile away and back the jpole gave a good 3db more than the quarter wave with 4 radials
[12:53] <daveake> Nice. In Buzz3 (rfm22b test payload) I wired the 1/4 wave aerial and 4 radials straight to the rfm22b
[12:53] <navrac> the quater wave works - but the jpole beat it hands down in my tests
[12:54] <daveake> Friend of mine at uni got a job designing aerials. Met up with him a year later. He said "I've been doing this for a yeasr and I still don't know how they work"
[12:54] <daveake> How does the radiation pattern compare?
[12:55] <navrac> actually it was almost identical the jpole was just stronger . The slim jim was pretty good but did have qa bit of a blank spot directly underneath.
[12:55] <navrac> so for range the slim jim won, but for a nice even radiation pattern the j pole was best overall.
[12:55] <daveake> Interesting
[12:56] <navrac> I think given that I was running 11dBm and the j pole, people were receiving it right up to the radio horizon of 300km (approx) at 5000m
[12:56] <navrac> I think you still had it at 280km which isnt bad at all
[12:57] <daveake> Yes, don't remember the exact figure but about there
[12:57] <daveake> That was with a co-linear. May have got further if I'd put the yagi up
[12:58] <navrac> well the radio horizon is 290km so I doubt you'd have got much further and then theres all the hassle of rotating it!

[15:59] <OZ1SKY_Brian> yes i know :-)
[15:59] <UpuWork> you said there was going to be some on Sat
[15:59] <OZ1SKY_Brian> -19dB from gb3vhf
[15:59] <UpuWork> good prediction :)
[16:00] <fsphil> hmm.. that's quite far
[16:00] <OZ1SKY_Brian> 854km
[16:01] <fsphil> I can only receive when I'm in the office
[16:01] <UpuWork> its quite high up
[16:01] <UpuWork> dunno what power it is
[16:02] <OZ1SKY_Brian> 30w
[16:02] <fsphil> 144430 your dial frequency?
[16:02] <OZ1SKY_Brian> Get a ballon up, should be good today :-)
[16:02] <OZ1SKY_Brian> 144428.5u
[16:05] <OZ1SKY_Brian> or 144430 if you got a cw mode
[16:05] <fsphil> typically my streamy thing has broken

[16:10] <daveake> Should be 2 flights - one BUZZ is a tiny payload; the other is a chain with AVA and CLOUD and possibly/hopefully on from CovBalloon
[16:10] <fsphil> the pink thing takes to the air again
[16:11] <OZ1SKY_Brian> ah ok saturday, not home saturday, maybe later, if its a float.
[16:11] <daveake> Cuurent plan: BUZZ will be an RFM22B on 434.2MHz. CLOUD will be an NTX2 as will AVA. One on .650 and other on .075. I forget which is on which.
[16:11] <daveake> BUZZ may float but that's not the current plan

[16:12] <daveake> There's always a plan
[16:12] <OZ1SKY_Brian> daveake ok we´ll see, would be nice to hear something here again, havent had much luck the last few launches
[16:12] <daveake> Can't remember ever following one though
[16:13] <OZ1SKY_Brian> but im also at the very outer rim
[16:13] <daveake> CLOUD will also have a backup tracker sending the RTTY as SMS texts to a phone at my home, where a program will relay the telemetry to habhub.
[16:13] <daveake> I've been testing that one today and it's going well
[16:14] <OZ1SKY_Brian> daveake sounds great, i hope i get a chance to hear it
[16:14] <daveake> CLOUD should have the Radiometrix logo in front of a camera, and a certain space adventurer in front of another.
[16:15] <daveake> OZ1SKY_Brian Both are 1600g hwowowyees, so with luck they should get up fairly high, especially the light one
[16:15] <daveake> So that should help you
[16:16] <daveake> Anyway, weather is king and we'll see what that does to the plans

[17:23] <Josh_> i also noticed that the habhub's balloon burst calculator tells you the amount of helium needed in metres3 whereas, for example, on the BOC website they would provide the measurement in metres2
[17:23] <fsphil> that's a typo on boc's site
[17:23] <fsphil> it is actually m3
[17:23] <SpeedEvil> You can't measure helium in meters^2
[17:23] <SpeedEvil> It's impossible
[17:23] <jonsowman> m² would not be helpful

[17:24] <Josh_> i thought that as well!

[17:24] <Josh_> but then seeing it on the BOC website i thought they would be too good for that....

[20:29] <Lunar_Lander> XD!
[20:30] <vk5gr_> we are all enroute to the launch site now - should launch in about 2-3 hours
[20:30] <Upu> good luck
[20:30] <daveake> +1
[20:30] <Elmar_PD3EM> good luck vk5gr_ !!
[20:30] <fsphil> ooh, I might be awake
[20:31] <Upu> the BBC tend to be very good at picking tunes to go with stuff
[20:31] <Lunar_Lander> yeah
[20:31] <vk5gr_> not sure what payload we are flying yet
[20:31] <Lunar_Lander> good luck vk5gr_
[20:32] <daveake> Yeah I thought that music worked really well
[20:32] <Upu> yup
[20:32] <vk5gr_> the landing site is a bit close to potential water and we dont want things to go for a swim like cameras etc
[20:32] <fsphil> Woob, perfect name for a band :)

[20:37] <Upu> http://www.youtube.com/watch?v=P8a4iiOnzsc
[20:37] <Lunar_Lander> and today I talked with some people at university if we can pressure test it

[20:38] <Elmar_PD3EM> thanks Upu
[20:39] <Upu> Chariots of Fire

[20:42] <griffonbot> Received email: Alexei Karpenko "Re: [UKHAS] last position payload"
[20:42] <Lunar_Lander> well as I said
[20:42] <Lunar_Lander> I want to investigate why geiger counters tend to fail above 22 km
[20:45] <fsphil> Top Gear went all Daft Punk for a while last year
[20:46] <Hiena> Guess, it's due the helmets.
[20:47] <griffonbot> Received email: Peter "[UKHAS] Re: last position payload"
[20:48] <Lunar_Lander> yea
[20:48] <griffonbot> Received email: Peter "[UKHAS] Re: last position payload"
[20:50] <Lunar_Lander> and they said, reaching 1000 pascals in their chambers is really easy
[20:50] <Lunar_Lander> so we can simulate reaching 31 km
[20:51] <nigelvh> Do you think it's the pressure or the temperature?
[20:51] <nigelvh> I have access to thermal and vacuum chambers at the university here.
[20:52] <nigelvh> So there is the option for testing
[20:52] <Lunar_Lander> I think the pressure could cause the HV system to spark or so
[20:52] <Lunar_Lander> temperature testing is also planned
[20:52] <nigelvh> Generally we coat the HV portions.
[20:52] <Lunar_Lander> but I think that the inside of the payload won't get that cold
[20:52] <Lunar_Lander> we have seen -25°C as an extreme I think

[20:52] <Elmar_PD3EM> Upu: I haven't edited the wiki yet. I want to test it first myself ;-)
[20:52] <Lunar_Lander> but only for a short time
[20:52] <Lunar_Lander> yeah Nigelvh, what do you use for coating?
[20:53] <nigelvh> It's just a conformal spray.
[20:53] <Lunar_Lander> ah
[20:53] <nigelvh> I don't recall the name
[20:53] <Lunar_Lander> OK
[20:53] <nigelvh> We have also potted them.
[20:53] <Lunar_Lander> IIRC the rocket people in the 1950's used silicon or so
[20:53] <Lunar_Lander> that stuff you use to close gaps on windows
[20:53] <Lunar_Lander> potted means?
[20:54] <nigelvh> Like fill a cup with epoxy resin, dunk the board in there, and let it all harden.
[20:54] <nigelvh> You pot the board in whatever container.
[20:54] <nigelvh> Like you'd pot a plant with soil
[20:54] <navrac_> or for the cheapskates cover it in araldite
[20:55] <Upu> no problems PD3EM just when your happy with it
[20:55] <fsphil> Lunar_Lander, are the counters not exposed?
[20:55] <Lunar_Lander> ah
[20:55] <Lunar_Lander> fsphil, the mightyohm one is a PCB with the Geiger tube clamped on it
[20:55] <Lunar_Lander> and at Lake Constance the geiger tube also was on top of the PCB
[20:55] <fsphil> is it kept inside the payload box or does it need to be outside?
[20:55] <Lunar_Lander> inside the box
[20:56] <Lunar_Lander> but it will still "see" the low pressure of course
[20:56] <fsphil> yea. was temperature I was thinking about - your right it will still be fairly warm in there
[20:56] <Lunar_Lander> yeah
[20:56] <Lunar_Lander> and low pressure -> possible corona discharge or so

[21:09] <fsphil> wish we had more here
[21:09] <schofieldau> Mostly cloudy. Isolated showers and the chance of thunderstorms from midday. Winds northerly averaging 20 to 30 km/h tending west to northwesterly up to 20 km/h by early evening.
[21:10] <schofieldau> hmm will thunderstorms interfear with a launch at all?

[21:10] <schofieldau> yeah I am
[21:10] <schofieldau> I'm in Adelaide
[21:10] <fsphil> shouldn't bother them unless it rains or there's gusty winds on the ground
[21:10] <schofieldau> that forecast applys for Wistow as well as far as I know
[21:10] <fsphil> they'll have launched by then anyway
[21:10] <fsphil> unless it goes into ISH time
[21:11] <schofieldau> also high fire danger

[21:11] <schofieldau> yay living in the scrub

[21:27] <Upu> I nearly swore on channel
[21:28] <Upu> that is stoopid
[21:28] <nigelvh> nearly swore is right
[21:28] <jonsowman> good lord
[21:28] <nigelvh> I see a 706 in there
[21:28] <fsphil> holy c***
[21:28] <Elmar_PD3EM> a crazy ham....
[21:28] <Lunar_Lander> is it about that car photo?
[21:28] <nigelvh> Also maybe a 2800
[21:28] <Lunar_Lander> is the car OK to watch?
[21:28] <Elmar_PD3EM> yep
[21:29] <nigelvh> I'm not sure you can fit that many antennas on a car roof.
[21:29] <Lunar_Lander> ROFL
[21:29] <fsphil> I'm sure wally is in there somewhere
[21:29] <Lunar_Lander> well
[21:29] <Lunar_Lander> when I went to Ham Radio 2010 with a ham friend of mine, he had a APRS tracker in the trunk I think
[21:29] <Lunar_Lander> and a small Yaesu radio there on the passenger side
[21:30] <nigelvh> On the dash? I think that's the 2800
[21:30] <Lunar_Lander> and he had a thing that looked like a telephone
[21:30] <fsphil> I'm trying to find a mount for the 817 on the dash
[21:30] <Lunar_Lander> and that telephone he could connect to the radio
[21:30] <nigelvh> Plus a pepsi cup
[21:30] <nigelvh> Also apparently texas seatcovers
[21:30] <Elmar_PD3EM> http://www.hamsource.com/817_mount/
[21:31] <Lunar_Lander> does anybody know more about that telephone device?
[21:31] <Lunar_Lander> xD nigelvh
[21:31] <jcoxon> evening eroomde
[21:31] <Lunar_Lander> hello jcoxon
[21:31] <fsphil> Elmar_PD3EM, something less permanent
[21:32] <fsphil> I was thinking of modifying the eeepc mount
[21:33] <Elmar_PD3EM> or a rubber matt on the dashboard
[21:33] <fsphil> would that be enough?
[21:33] <Lunar_Lander> a radio is quite heavy
[21:33] <nigelvh> Depends on how vigorous your driving is.
[21:33] <fsphil> I'm pretty slow :)
[21:33] <Lunar_Lander> I won't trust the friction on the mat
[21:33] <Upu> http://ava.upuaut.net/files/habmobile.jpg <- remove the entirely useless ipod connector that doesn't work and slide in resulting hole
[21:33] <nigelvh> I can put my ft-8900 on the dash with rubber feet
[21:33] <fsphil> only been driving for a year or so
[21:34] <nigelvh> It stays pretty good.
[21:34] <Elmar_PD3EM> maybe... there are some special matts
[21:34] <fsphil> nice setup Upu
[21:34] <Elmar_PD3EM> maybe fix it with a strap
[21:35] <Lunar_Lander> may I interject a question about Scotland?
[21:35] <jcoxon> i have a strip of velcro
[21:35] <Elmar_PD3EM> very nice Upu!
[21:35] <fsphil> ack aye Lunar_Lander
[21:35] <jcoxon> on the bottom of my 817 and on my car
[21:35] <daveake> Upu I think that's the same Netbook holder I have
[21:35] <nigelvh> Yeah, some velcro would work fine.
[21:35] <Lunar_Lander> a friend just said that she was in Scotland when there was so much slow that the minister of transportation resigned
[21:35] <fsphil> velcro... hmm
[21:35] <Upu> something from ebay
[21:35] <Lunar_Lander> and she said that the shops closed earlier than normal
[21:35] <Lunar_Lander> is that true?
[21:35] <Lunar_Lander> not slow
[21:35] <Lunar_Lander> snow
[21:36] <daveake> Yep. Says "Now you can use your Netbook while driving" on the box!!

[21:40] <Elmar_PD3EM> just another thing I was thinking about......
[21:41] <Elmar_PD3EM> is there an option on spacenearus to plot a chase car on the map from APRS positions?
[21:42] <natrium42> there's a script that you run on your local machine
[21:42] <natrium42> https://github.com/akarpenko/APRS2Tracker
[21:42] <Darkside> morning all
[21:43] <natrium42> yo Darkside

[21:43] <natrium42> donna be on the tracker?
[21:43] Action: fsphil fixes his hair
[21:43] <Elmar_PD3EM> thanks! but it's not a configurable option for a launch to put the chase car on the map via APRS backbone?

[21:44] <Darkside> Elmar_PD3EM: no
[21:44] <Elmar_PD3EM> natrium42: maybe in the future
[21:44] <Darkside> it would be useful though
[21:44] <Darkside> as we have aprs in most of our cars
[21:44] <Laurenceb_> is this a floater?
[21:44] <Darkside> uh
[21:44] <Darkside> no
[21:44] <Darkside> Laurenceb_: ground level here is 400m alt
[21:44] <Laurenceb_> sure
[21:44] <Laurenceb_> i mean is the idea to float
[21:44] <Elmar_PD3EM> Darkside: that's what I was thinking about
[21:44] <Laurenceb_> whats the aim?
[21:45] <Laurenceb_> for the flight
[21:45] <Darkside> Laurenceb_: its a promo launch for a tv show
[21:45] <Laurenceb_> ah
[21:45] <Laurenceb_> what envelope?
[21:45] <Darkside> 1kg hwoyee
[21:45] <Laurenceb_> ok
[21:45] <Laurenceb_> should be interesting
[21:45] <Laurenceb_> is the payload heavy?
[21:45] <natrium42> Elmar_PD3EM: the problem is that there is currently no way to define a mission on spacenear.us, and if we tracked all APRS flights the tracker would get messy
[21:46] <Elmar_PD3EM> Darkside: maybe a thing to think about for the spacenearus maintainers
[21:46] <Darkside> bahahaha
[21:46] <Darkside> terry is hillarious in front of a camera
[21:47] <Elmar_PD3EM> query the APRS backbone for a configured call and put it on the map
[21:47] <natrium42> that's what the script does
[21:47] <Upu> do you want the live predictions loading Darkside ?
[21:47] <Elmar_PD3EM> ok
[21:48] <natrium42> you give it a list of callsigns and it will bridge them to the tracker
[21:48] <Lunar_Lander> btw Elmar_PD3EM I'll write that guy with the american balloon
[21:48] <Lunar_Lander> if he can send me the experiment report
[21:48] <Elmar_PD3EM> great Lunar_Lander
[21:48] <Upu> oh you already did it
[21:49] <Elmar_PD3EM> natrium42: but wouldn't it be better if that can be configured on the server?
[21:50] <natrium42> yeah, sure
[21:50] <Elmar_PD3EM> natrium42: together with the balloon?
[21:50] <natrium42> next gen tracker is under development
[21:50] <Elmar_PD3EM> natrium42: ok great!
[21:51] <natrium42> i also worked a bit on a website to replace arhab launch list
[21:51] <natrium42> but didn't have time to finish it
[21:51] <OZ1SKY_Brian> daveake yes im 15km north of Arhus
[21:52] <natrium42> it's basically a calendar (similar to gcalendar) where groups can schedule launches
[21:52] <Darkside> we're basically ready to launch here, balloon is almost filled
[21:52] <Elmar_PD3EM> time is always the problem natrium42 I still need 48 hours or more every day ;-)
[21:52] <natrium42> yeah :S
[21:53] <OZ1SKY_Brian> jcoxon ping, im here now

[21:58] <daveake> s'ok :)
[21:58] <OZ1SKY_Brian> daveake ok if you gone from arhus airport to arhus you passed right by my

[22:05] <Lunar_Lander> YAY
[22:05] <OZ1SKY_Brian> Lunar_Lander yes but when i think about it, Denmark is a crappy place to launch ballons, if you want to recover them again, too much water around us.
[22:05] <daveake> LL yes big rivals
[22:05] <Lunar_Lander> hm yea
[22:06] <Lunar_Lander> yeah, TetraPak now has these commercials with a rabbit explaining how wood is good as a resource
[22:06] <OZ1SKY_Brian> daveake if you stop by some other time, let me know so we can have a chat
[22:06] <Lunar_Lander> but the thing is that you need aluminum and plastic as well
[22:06] <daveake> will do :)
[22:06] <Lunar_Lander> and I think there is only one company in the world as of today that can seperate the carton layers
[22:06] <Lunar_Lander> in South America
[22:06] <Lunar_Lander> they use a plasma or so

[22:10] <OZ1SKY_Brian> that could be fun, im in
[22:10] <Lunar_Lander> yea
[22:10] <Lunar_Lander> I hope I get my first balloons going soon
[22:11] <Lunar_Lander> earlier I said, that also might be interesting to daveake , that I today asked at university if they have a means to simulate the pressure at 30 km
[22:11] <Lunar_Lander> and they have
[22:11] <Lunar_Lander> and thus I could try to pressure test devices
[22:11] <OZ1SKY_Brian> i just feel Denmark is a bad place to launch from, we got water allmost all around us, so no mater what win directions we got, there is a very good chance it will end up in the water, unless its a float
[22:11] <Lunar_Lander> and I want to look at why geiger counters fail between 20 and 30 km

[22:14] <OZ1SKY_Brian> Lunar_Lander im a paying member :-)
[22:14] <Lunar_Lander> heathkid, well the Lake Constance launches as well as Apex II showed that the counter suddenly go to 0 counts
[22:14] <Lunar_Lander> cool OZ1SKY_Brian ! :)
[22:14] <OZ1SKY_Brian> Lunar_Lander been since day 1
[22:15] <Lunar_Lander> and I suspect that corona discharge or something else in the HV part happens
[22:15] <Lunar_Lander> yeah
[22:15] <schofieldau> Darkside: no live webcast this time?
[22:15] <Elmar_PD3EM> Darkside: normally 70% is cut out... so 70 hrs filming leaves 1 hour film

[22:17] <heathkid> although the best vacuum I can get is in one of our SEMs
[22:18] <Lunar_Lander> OZ1SKY_Brian, you mean that their rockets get to a high altitude?

[22:18] <Lunar_Lander> yeah I think guidance was a problem last time
[22:18] <nigelvh> Elmar_PD3EM: No problem. It's about 15:00 here. So I've got a slight advantage.
[22:18] <Lunar_Lander> had that worked well, they surely would have flown higher

[22:22] <Lunar_Lander> why did it take one year or so to solve that LOX valve problem?
[22:23] <OZ1SKY_Brian> Lunar_Lander what im working on is a TLM/Video solution from the launch platform and launch boat. At sime point the news stations will not cover it live anymore, and then they will relay on there own backbone to the landside.

[22:25] <OZ1SKY_Brian> Lunar_Lander the VSAT or Iridium uplink are too low BW for a good TLM/Video signal, so a microwave link is the best solution.
[22:25] <Lunar_Lander> yeah
[22:26] <Lunar_Lander> something in the mm range?
[22:26] <schofieldau> filming will be worth it
[22:26] <schofieldau> keen for the video
[22:26] <Lunar_Lander> 2 GHz or so?
[22:26] <OZ1SKY_Brian> Lunar_Lander it will work fine for a static video, like a news reporter, but for a quick camara resonce its no good
[22:26] <Lunar_Lander> the microwave solution?
[22:27] <Lunar_Lander> is the bitrate or so too low?
[22:27] <OZ1SKY_Brian> microwave link, IP packed to the island and then feed to the internet from a good connection
[22:28] <Lunar_Lander> yea
[22:28] <Lunar_Lander> that really doesn't sound to be too optimal for a rocket launch
[22:28] <OZ1SKY_Brian> microwave will do 25-50mbps when you calculate the s/n and free space loss

[22:31] <Lunar_Lander> yeah
[22:31] <Lunar_Lander> btw was the frequency I predicted right?
[22:31] <Lunar_Lander> I said 2 GHz
[22:32] <Laurenceb_> launch soon?
[22:33] <OZ1SKY_Brian> Lunar_Lander video was 1240 and 2330MHz
[22:33] <OZ1SKY_Brian> sri 2340
[22:34] <Lunar_Lander> ah
[22:34] <Lunar_Lander> then my prediction wasn't that off
[22:34] <Lunar_Lander> :)
[22:34] <G0DJA> 1240 is about 23cm and 23300 13cm area
[22:34] <OZ1SKY_Brian> Lunar_Lander and a 10GHz radar tracking beacon
[22:34] <Lunar_Lander> yea
[22:34] <OZ1SKY_Brian> G0DJA thats right
[22:34] <G0DJA> Both still, technically, UHF
[22:34] <Lunar_Lander> yea
[22:34] <G0DJA> 2330 - sorry
[22:35] <Lunar_Lander> and 12 GHz is Satellite TV

[22:37] <Lunar_Lander> and I was told that the frequency is the reason that in rainy weather TV cuts out
[22:37] <OZ1SKY_Brian> Just above the KU band satellite uplinks at 13-14GHz
[22:37] <Lunar_Lander> yea

[22:39] <griffonbot> @darksidelemm: http://t.co/jZaiyxO7 What to do with the spare balloon.. Launch it of course! #projecthorus [http://twitter.com/darksidelemm/status/179698266848509952]
[22:39] <Darkside> well, soon
[22:39] <OZ1SKY_Brian> nigelvh yes water and snow will reduce the signal, if you go to a higher freq it will get better, but the signal path att. will also rice.
[22:40] <OZ1SKY_Brian> rise
[22:40] <nigelvh> Yeah. Generally we do ok.
[22:40] <zindello> Lol good on ya Mark!
[22:40] <G0DJA> Get a nice frosty day to get rid of the moist air is best but on 3cm rain and hail can be an advantage!
[22:40] <OZ1SKY_Brian> G0DJA yeah we had some tropo today, picked up gb3vhf here on 144430

[23:52] <zindello> You don't get, err, taken off the road, until it's close to 20% at those sppeds :P
[23:52] <zindello> speeds*
[23:53] <zindello> Not that I'd imagine any foxhunt or baloon chase team would every go over the posted speed limit :P
[23:53] <vk5gr> we arent
[23:53] <vk5gr> acually we cant in this old girl
[23:53] <zindello> You guys coming to Mt G this year?
[23:53] <Darkside> dont think so
[23:54] <Darkside> oh dear
[23:54] <Darkside> i forgot our speed appeared on the tracker
[23:54] <zindello> ?
[23:54] <Darkside> 121.6 lol
[23:54] <Darkside> >_>
[23:54] <Darkside> speed limit is 130 here of course
[23:54] <zindello> It is?
[23:54] <Darkside> no lol
[23:54] <zindello> Heh
[23:54] <zindello> Not NT!
[23:55] <zindello> You really are playing catch-up.
[23:55] <zindello> Not like 21, we stopped what? 3 times?
[23:56] <Darkside> yeah lol
[23:56] <Darkside> we;re stuck behind a slowpoke
[23:57] Action: SpeedEvil hopes for a 'pop' soon.
[23:57] <Darkside> pff
[23:57] <Darkside> umlikely
[23:57] <zindello> Going to turn soon
[23:58] <SpeedEvil> I was assuming the tracker was set to the desired burst height.
[23:58] <zindello> Is the predictor based on altitude?
[23:58] <SpeedEvil> zindello: yes
[23:58] vk2fp (7ca99f4b@gateway/web/freenode/ip.124.169.159.75) left irc: Ping timeout: 245 seconds
[23:58] <zindello> Because if so, that's a LONG way for it to climb in that short distance.
[23:58] <Darkside> it is
[23:58] <SpeedEvil> zindello: It uses near-real-time weather data to compute the path.
[23:59] <zindello> SpeedEvil: Yeah, I know Mark showed it to me, it's just if the expected altitude is 30km, then it's got a long way to go up, in what the predictor marks as a relatively short distance.
[23:59] <SpeedEvil> Indeed.
[23:59] <SpeedEvil> Crossing a weatehr front
[23:59] <Darkside> slow wings
[23:59] <Darkside> winds

[23:59] <zindello> Mmm
[23:59] <zindello> puts the burst over an hour away too
