[00:22] <fsphil-laptop> did you take that?
[00:22] <Darkside> yes
[00:22] <fsphil-laptop> nice
[00:23] <Darkside> 500mm f8 tamron lens, and some solar filter
[00:23] <Darkside> absolute pain to get the lens focused
[00:23] <NigeyS> tasty, get a ha filter on there to :D
[00:23] <fsphil-laptop> lol
[00:23] <Darkside> yeah i wish
[00:23] <NigeyS> seen the price of them :O :(
[00:24] <Darkside> http://i.imgur.com/auCwn.jpg
[00:24] <fsphil-laptop> for that price, I want them hand delivered by Patrick Moore himself

[00:24] <NigeyS> lol phil
[00:24] <NigeyS> yup £200 for a 2inch is about right
[00:25] <fsphil-laptop> I'd love to take a look through a solar scope some day
[00:25] <fsphil-laptop> (with proper filters of course .. I like my eyes)
[00:25] <NigeyS> oo
[00:25] <NigeyS> Ha(7nm), Hb, OIII & SII: £265.00
[00:26] <Darkside> jeez
[00:26] <NigeyS> not a bad deal, but for 1.25" not "
[00:26] <NigeyS> 2"*
[00:26] <Darkside> mm yhe front of this 500mm lens is about 3" lol
[00:27] <NigeyS> bloody ell

[08:30] <UpuWork> hello there
[08:31] <HighAltitudeFrid> im constructing a high altitude balloon project al www.highaltitudefridge.com
[08:31] <HighAltitudeFrid> im working on the remote telemetry
[08:31] <UpuWork> ok
[08:31] <UpuWork> you're not really launching a fridge are you ?
[08:31] <HighAltitudeFrid> tring to receive RTTY with dl-fldig

[08:33] <UpuWork> anyway yes the RTTY
[08:33] <HighAltitudeFrid> im tring to output a rtty message to a wav file with minimodem y decoding with dl-fldigi
[08:33] <HighAltitudeFrid> without luck
[08:33] <HighAltitudeFrid> :-(
[08:34] <UpuWork> whats generating the RTTY ?
[08:34] <HighAltitudeFrid> i found a software for linux (im using beagleboard as fligh computer)
[08:34] <HighAltitudeFrid> minimodem, a software for linux
[08:34] <UpuWork> ok
[08:34] <UpuWork> and what are you trying to do exactly ?
[08:35] <HighAltitudeFrid> coding test telemetry string with minimodem and decode with dl-fldigi (doing playback of the previosly recorded wav)
[08:35] <UpuWork> ah ok
[08:35] <UpuWork> so you have the wav file ?

[08:38] <HighAltitudeFrid> ....
[08:38] <UpuWork> what did you encode it as ?
[08:38] <daveake> Let us know what you've encoded as (baud rate, stop bits, data bits), upload the file and we'll have a go
[08:39] <HighAltitudeFrid> ok
[08:39] <HighAltitudeFrid> one moments
[08:39] <UpuWork> yeah what Dave said though I have to go out on site

[08:45] <HighAltitudeFrid> i cant decode. arg!
[08:45] <HighAltitudeFrid> :-)
[08:46] <UpuWork> whats the shift ?
[08:46] <daveake> About 180
[08:47] <UpuWork> I only see one line
[08:47] <HighAltitudeFrid> yep, i can code/decode perfect with minimodem, but i want to use dl-fldigi to decode with HAB mode
[08:47] <eroomde> morning all
[08:47] <HighAltitudeFrid> yes
[08:47] <UpuWork> morning Ed
[08:47] <HighAltitudeFrid> 1234567890 ABC?
[08:48] <daveake> My copy of dl-fldigi isn't playing it back right, so I have it playing from a media player out the audio out then back in the audio in
[08:48] <UpuWork> I need to shoot back soon
[08:48] <HighAltitudeFrid> and you able to decode the string?
[08:50] <daveake> nope
[08:50] <HighAltitudeFrid> arg!
[08:50] <HighAltitudeFrid> what software are you using to code the RTTY string?
[08:51] <daveake> OK gottit
[08:51] <HighAltitudeFrid> i found package.c from pegasus project
[08:51] <HighAltitudeFrid> hey!
[08:51] <HighAltitudeFrid> how?
[08:51] <HighAltitudeFrid> :-)
[08:51] <daveake> I had to set ... 180 shift, 45 baud, baudot, 1 stop
[08:51] <HighAltitudeFrid> i'll try
[08:52] <fsphil> I'd suggest using 7-bit ascii instead of baudot
[08:52] <HighAltitudeFrid> why fsphil?
[08:52] <fsphil> it'll decode a bit better if conditions are bad
[08:52] <eroomde> more robust
[08:52] <HighAltitudeFrid> ok, thank you
[08:53] <eroomde> in baudot if you loose the bit that defines what register to use, you loose the entire subsequent 4-5 bits of info
[08:53] <fsphil> ascii really is a silly name
[08:53] MrCraig (~MrCraig@host86-176-41-103.range86-176.btcentralplus.com) joined #highaltitude.
[08:54] <HighAltitudeFrid> i'm playing the wav file directly in dl-fldigi but no results with this settings
[08:54] <daveake> Also I suggest you use 50 baud, as everyone does :)
[08:54] <HighAltitudeFrid> ok : )
[08:55] <daveake> No, your file won't play back in that. fldigi has a particular format (which fsphil will remind me of in a moment) and doesn't work with other formats
[08:55] <fsphil> 8000hz, 16-bit mono :)
[08:55] <daveake> So I went media player --> sound output --> audio cable --> sound input --> dldigi
[08:55] <eroomde> nice
[08:56] <fsphil> one of the (few) nice features of pulseaudio on linux is it's really simple to record the output
[08:59] <HighAltitudeFrid> aaaaa
[08:59] <HighAltitudeFrid> thats the point
[09:00] Action: fsphil 's brain catches up with HighAltitudeFrid's nick
[09:00] <fsphil> what?
[09:00] <HighAltitudeFrid> i havent a cable here now but i will try this afternoon

[10:31] <golddragon24> Anyone know what Google Earth wants when it reads GPS? I've got a chip feeding a NEMA stream into an FTDI chip, but google earth doesn't seem to pick it up. The TX and RX leds light, so it's trying.

[10:33] <Darkside> google earth wont do that
[10:33] <Darkside> by reating a gps, it means it'll read waypoints off a gps
[10:34] <daveake> Hmmmm .... I'm pretty sure it does do that. I'm pretty sure I've done it.

[10:45] <eroomde> yeah g-earth should be able to interface directly
[10:45] <eroomde> tho i recall rteading it was a pro feature
[10:46] <daveake> It certainly used to be, but I think they added it to the free version
[10:47] <daveake> I did pay for the pro version a while back just for that reason

[10:48] <golddragon24> I've got the free version, and it doesn't look greyed out or anything. I assume it's some baud rate thing or something, but I'm too lazy right now to figure out how to change it.
[10:50] <daveake> Is the GPS sending out GPRMC sentences?
[10:50] <SpeedEvil> point a terminal progfram at the GPS
[10:50] <SpeedEvil> does it actually output stuff?
[10:50] <daveake> <golddragon24> I can see the output in a terminal/other programs.

[11:41] <daveake> :)
[11:44] <navrac> just made an irritatingly large mistake :-(
[11:44] <Darkside> oh navrac
[11:44] <Darkside> the uplink frequencis you mentioned
[11:44] <Darkside> thats out of the ham bands...
[11:45] <navrac> thought I'd be clever and cover the sensitive parts with silicon gunk to stop wires fracturing and add a bit of thermaql insulation
[11:46] <daveake> and .....
[11:46] <navrac> had to try to scrape it off so i could upload to the arduino as it kept failing, the rfm22b now gives out about -10db compared to yesterday
[11:46] <daveake> oops
[11:46] <Darkside> ouch
[11:46] <Darkside> navrac: again, your uplink frequencies
[11:46] <navrac> the frequencies are UK only for 'model control' including airbourne
[11:46] <Darkside> uhh
[11:46] <Darkside> hrmmm
[11:46] <Darkside> i'd still keep within the ham bands
[11:47] <Darkside> that way people can experiment with some higher power uplink options
[11:47] <navrac> well true except the uk license doesnt allow you to tx to non attended airbourne devices
[11:48] <Darkside> "hello this is M6UPU testing a data mode"
[11:48] <Darkside> <BOOPYDOOPYBOOPYDOOPY>
[11:48] <Darkside> "thanks guys, testing complete"
[11:48] <navrac> but in theory you can use any uplink frequency you like - so it would be possible to use an rfm22 as the source then a linear amp
[11:48] <Darkside> do it on the upper end of 440-450MHz
[11:48] <number10> hard to find is the extra woo woo eroomde
[11:49] <navrac> well i'll stick with what I've got - but will try it for the next flight
[11:49] <UpuWork> wut ? :)
[11:50] <Darkside> navrac: its a iny code change
[11:50] <Darkside> also whats the shift for the uplink
[11:50] <Darkside> if you can make it fit within a 3KHZ window then people can try doing uplink using their ham radios
[11:50] <navrac> yes but all the aerial is worked out for 459MHz and its fsk 500 baud
[11:50] <Darkside> what shift
[11:51] <UpuWork> this tonna is built like a brick outhouse
[11:51] <Darkside> thatd set separately
[11:51] <number10> how much does it weigh UpuWork
[11:52] <daveake> and how strong is your house?
[11:53] <navrac> the difficulty is that the data format including header etc is handled by the rfm22 - it will take a bit of time to work out excatly whats being used internally. But I will change to the ham bands for the next flight and publish the data format so we can play high power uplinks - anyway if I put it on the ham bands I'm not allowed to tx to it!
[11:54] <daveake> UpuWork is this is? http://www.youtube.com/watch?v=eVunOajOwyQ
[11:54] <Darkside> navrac: what i mean is you record the output of the rfm22b using another radio
[11:54] <Darkside> and play it back
[11:54] <daveake> it
[11:54] <Darkside> navrac: but the only way that will work is to keep teh shift within the passband of a normal ham radio
[11:54] <navrac> interesting idea, hadnt thought of that
[11:55] <UpuWork> lol daveake not quite
[11:55] <daveake> Like that one was ever going to work :)

[12:06] <daveake> :(
[12:06] <Randomskk> rather than fly two separate

[12:09] <Randomskk> sitting through an entire lecture course on "digital transmission" unbearably hammered home the point of how primitive rtty is

[12:10] <fsphil> the only reason it's popular :)
[12:10] <daveake> And it sounds so nice at 50 baud :)
[12:10] <Randomskk> the adf7012 can do 150hz shift mfsk, which is a bit pants but I guess lets me up the data rate a bit
[12:10] <Randomskk> and if I say 2khz bandwidth that's enough for M=12 or so
[12:10] <Randomskk> hmm maybe I could get away with 16

[13:19] <jonsowman> in the same way the standalone does at the moment

[14:32] <Randomskk> though I haven't actually.. checked
[14:32] <Randomskk> >_>
[14:32] <eroomde> i'm gonna solder up a new hedgehog this eve Randomskk
[14:33] <eroomde> trying to find the short in the current one is so difficult with the bottom layer being so crowded with stuff
[14:33] <eroomde> so i'm just gonna cook the top side in the oven and try it out
[14:34] <Randomskk> what, just reflow?
[14:34] <Randomskk> got a microscope?
[14:34] <eroomde> nope
[14:34] <Randomskk> loupe?
[14:34] <eroomde> nope
[14:34] <Randomskk> you should sort that
[14:34] <eroomde> i have an illuminated magnifying glass
[14:34] <Randomskk> those are pants
[14:35] <eroomde> but the bottom side is just do croded and 3d that stuff i want to meter is physically occluded
[14:35] <eroomde> which is why i want to just make a new one with just the top side populated
[14:35] <Randomskk> that's why stereo microscopes where you can hold and rotate the thing is so good
[14:35] <Randomskk> but yea fair enough
[14:35] <eroomde> as that's super simple and easy to see
[14:35] <Randomskk> btw how did you solder the bottom smt stuff?
[14:35] <eroomde> yes i do miss the cusf stereo
[14:35] <Randomskk> also why are you using picoblade for battery?
[14:35] <eroomde> that was great
[14:35] <Randomskk> it's so good :P
[14:35] <eroomde> picoblade can take 1A
[14:35] <eroomde> which is vast
[14:36] <Randomskk> yea but don't you now have to reterminate the battery's JST or whatever?
[14:36] <Randomskk> addmitedly I'm tempted to get into the picoblade system
[14:36] <Randomskk> but yea did you reflow or hand solder the top side stuff?
[14:36] <Randomskk> s/top/bottom I guess
[14:36] <Randomskk> connectors
[14:36] <eroomde> hand soldered bottom
[14:36] <Randomskk> oh also, you reflowed the antenna? I thought the datasheet was like "btw pls to be hand soldering"
[14:36] <daveake> My chase car is sunk at sea
[14:36] <Randomskk> iron or hot air?
[14:37] <eroomde> iron
[14:37] <daveake> I can never remember which is latitude and which longitude ....
[14:37] <Randomskk> fair enough
[14:37] <eroomde> my battery doesn't come with anything
[14:37] <Randomskk> bet that was fun
[14:37] <eroomde> it's just a pp3
[14:37] <Randomskk> oh okay
[14:37] <eroomde> so, reflow on top, smd side
[14:37] <eroomde> reflow: http://www.flickr.com/photos/eroomde/6964024203/in/photostream
[14:38] <eroomde> by hand with iron: http://www.flickr.com/photos/eroomde/6964024647/in/photostream
[14:38] <Randomskk> yea
[14:39] <Randomskk> it makes me a bit sad that the ntx2's shield is the wrong way to shield against the smps :P but I guess the PCB's ground planes count
[14:39] <eroomde> so you can see just having the top side should be much easier to debug
[14:39] <Randomskk> yea totally
[14:39] <eroomde> and then if no short there, i can add components to the bottom one by one
[14:39] <eroomde> testing for a short each time

[14:40] <eroomde> i think on v0.2 i'll increase the ground plane isolation
[14:40] <eroomde> i need to get a telly of things to change started really

[15:01] <Lunar_LanderU> hello
[15:01] <PD3EM> hi LL
[15:01] <Lunar_LanderU> UpuWork: do you have a moment?
[15:01] <Lunar_LanderU> hi PD3EM
[15:02] <_Hix> hi Lunar_LanderU
[15:02] <Lunar_LanderU> hi _Hix
[15:02] <PD3EM> just started with my first Arduino Uno board... ;-)
[15:03] <Lunar_LanderU> cool
[15:03] <Lunar_LanderU> what did you do with it?
[15:03] <PD3EM> yep
[15:04] <PD3EM> I connected it to my PC as com 27 but it is also using com3 where my microham PTT is... :-(
[15:04] <PD3EM> works better on my laptop on com4
[15:04] <Lunar_LanderU> yea
[15:04] <Lunar_LanderU> somewhere I read that a low COM number is better
[15:05] <PD3EM> yep but com1 tru com26 are in use
[15:05] <navrac> im on com30 on my laptop , seems to be ok
[15:05] <daveake> COM number doesn't matter
[15:06] <PD3EM> yep. its working on com27 but also triggers ptt on com3...
[15:06] <Lunar_LanderU> oh
[15:06] <Lunar_LanderU> daveake: now soldered headers to the GPS
[15:07] <PD3EM> programmed my callsign in cw to the blinking led ;-)
[15:07] <daveake> :)
[15:07] <Lunar_LanderU> I can try it later probably, as I found a 3.3V voltage regulator in my collections
[15:07] <Lunar_LanderU> because the respective pin doesn't work as I learned
[15:07] <_Hix> right Ive connected the uBLox to the breadboard and connected GND and VCC and connected TX from uBlox to RX on FTDI
[15:07] <_Hix> Opened Hyperterminal on COM12
[15:07] <PD3EM> gonna attach some hardware later this weekend\
[15:07] <_Hix> but not seeing anything
[15:08] <Lunar_LanderU> PD3EM: cool, so you "modded" the Blink program
[15:08] <daveake> I'm adding chase-car-upload to my car PC program. First attempt landed near the Seychelle's :p
[15:08] <Lunar_LanderU> xD
[15:08] <_Hix> Do I have to send a command to the uBlox to see NMEA?
[15:08] <PD3EM> Lunar_LanderU: LOL indeed ;-) that was an easy one without the need for extra components
[15:08] <daveake> _Hix Shouldn't do, no. It should emit some sentences anyway. It's at 9600 btw
[15:09] <_Hix> ahhh 4800 try again :)
[15:09] <number10> I am of to syechelles to help chase daveake
[15:09] <daveake> Cheers
[15:09] <daveake> Having now put lat/long the right way round, it's back home. Sadly.
[15:10] <navrac> paging upuwork
[15:10] <Lunar_LanderU> can we have a DeLorean for chasing?
[15:10] <Lunar_LanderU> :)
[15:11] <_Hix> daveake, 9600, 8 data bits, no parity, 1 stop bit, flow control hardware. Correct?
[15:12] <daveake> You want a shit car made of shit than handled like shit and didn't go like shit off a shovel?
[15:12] <_Hix> :)
[15:13] <_Hix> I heard there were all sorts of profanities hidden in the real cars
[15:13] <jonsowman> daveake: precisely
[15:13] <Lunar_LanderU> XD daveake
[15:13] <daveake> _Hix no need for the flow control; just make sure your code keeps up :)
[15:14] <daveake> Don't recall seeing an embedded GPS that has CTS/RTS
[15:14] <_Hix> daveake, code? I've literally connected the GPS module to a breadboard and FTDI to the board from the usb port on COM12
[15:15] <daveake> I was talking about the future :p
[15:15] <_Hix> ahh
[15:15] <daveake> Anyhoo, as you said but no flow control
[15:16] <Lunar_LanderU> daveake: yeah, the DeLorean brought several people through a time span of 130 years
[15:16] <Lunar_LanderU> xD
[15:16] <daveake> Back to when it would have seemed like a good car
[15:16] <_Hix> Well I'm seeing nothing in Hyperterminal
[15:16] <daveake> Rx <--> Tx ?
[15:23] <_Hix> Nope nothing. Back to checking things over again
[15:24] <daveake> Stick a voltmeter on the Tx line from the GPS. Should see 3V-ish but it should bounce around
[15:26] <_Hix> yup 2.43 - 2.44
[15:27] <_Hix> ahhh - something is not giving enough juice - outside +-10%
[15:27] <daveake> Prolly 50mA limit from your FTDI
[15:28] <daveake> Check the GPS V+ power
[15:29] <Lunar_LanderU> and this shows why a power supply is needed
[15:29] <Lunar_LanderU> :)
[15:29] <Lunar_LanderU> daveake: as I said I pulled that 3.3V regulator from my collection, I probably ordered 2 when I once soldered Kostas' board
[15:30] <Lunar_LanderU> I only have to get the appropiate capacitors and then I can have a power supply on the veroboard :)

[15:37] <Lunar_LanderU> ah
[15:38] <Lunar_LanderU> wb
[15:38] <Upu> hey Lunar_LanderU
[15:38] <Upu> back now
[15:38] <_Hix> ah you got em the wrong eay round earlier i think i saw
[15:38] <Upu> what can I do for you
[15:38] <Lunar_LanderU> nigelvh: what was the problem?
[15:38] <_Hix> hey upu
[15:38] <Upu> I see NMEA Hix
[15:38] <Upu> :)
[15:38] <Lunar_LanderU> Upu: headers soldered to GPS and I found a 3.3V regulator in my collections xD
[15:38] <_Hix> :D
[15:39] <nigelvh> It wouldn't idle, and would die as soon as I let off the gas, but would run fine as long as I kept my foot on the gas. Took my till yesterday to figure out what started it about two weeks ago. I filled up the tank. Damn gas station had water in the gas! Got some water remover, and filled the tank with fresh gas. All better.
[15:39] <Upu> cool
[15:39] <Lunar_LanderU> nigelvh: OHHH
[15:39] <Lunar_LanderU> sounds like Back to the Future III
[15:40] <nigelvh> I quit after back to the future 1.
[15:40] <Lunar_LanderU> where they put the alcohol in the tank and the injection pump flies out
[15:40] <Lunar_LanderU> xD
[15:40] <Dan-K2VOL> water remover, what exactly is that doing in the gas tank
[15:40] <_Hix> now i need to translate NMEA into understandable
[15:40] <Dan-K2VOL> fusion?
[15:40] <daveake> _Hix yep, have fun :-)
[15:40] <nigelvh> Yeah, my car now runs on cold fusion.
[15:40] <Dan-K2VOL> better hope it's cold if it's happening in the gas tank!
[15:40] <nigelvh> Exactly
[15:41] <_Hix> fun in the needle in the eye sense :D
[15:41] <nigelvh> Anyway, needless to say, I won't be filling up at that station again.
[15:41] <_Hix> cool - stuff works :D
[15:42] <Dan-K2VOL> nigelvh that's why you drain a bit of fuel out everytime after getting gas in an airplane.
[15:42] <nigelvh> Yeah, that's kinda a pain in the ass in a car.
[15:43] <_Hix> ha - got lock i see $GPGLL,5140.98090,N,00001.68380,E,154226.00,A,A*63

[15:43] <kokey> I took my car in for a service today, mainly since I suspect it hasn't seen new spark plugs for a long time
[15:43] <kokey> turns out they do everything except the spark plugs
[15:43] <Lunar_LanderU> nigelvh: LOL I just remember the end of BTTF I and the start of II
[15:43] <Lunar_LanderU> where he takes the trash and puts it into the Mr. Fusion
[15:44] <Lunar_LanderU> that fusion generator
[15:44] <nigelvh> So, I once in a while use this stuff called Sea Foam, it's a petroleum based product that's supposed to clean shit out, as well as removes water from the system.
[15:44] <nigelvh> Just dump it in the gas tank.
[15:44] <_Hix> nigelvh, W.O.T fro a few miles does that in my car :D
[15:44] <daveake> _hix that's good. You also need the GGA sentence for altitude
[15:44] <nigelvh> Back when I had my older carburated car, you could dump the shit straight down the carburator while it was running.
[15:44] <kokey> just heat the fuel tank up to 100.0C, the water will evaporate
[15:45] <Lunar_LanderU> XD

[15:45] <Lunar_LanderU> xD
[15:45] <nigelvh> Ah.
[15:46] <nigelvh> Lunar_LanderU: These days I drive a '93 Subaru Legacy wagon.
[15:46] <Lunar_LanderU> ah
[15:46] <Lunar_LanderU> and it is difficult you say?
[15:46] <nigelvh> Difficult?
[15:46] <Lunar_LanderU> yeah I mean a lot of maintenance is neede
[15:47] <Lunar_LanderU> +d
[15:47] <Lunar_LanderU> and problems appearing
[15:47] <nigelvh> Oh, no. It's a great reliable car. Just doesn't run so good when you put watery gas in it.
[15:47] <Lunar_LanderU> ah
[15:47] <_Hix> Boxers are the cooles sounding engines
[15:47] <_Hix> coolest
[15:47] <nigelvh> It has the standard things like every other car. Oil changes, fluid checks, etc.
[15:47] <Lunar_LanderU> yea
[15:47] <_Hix> Vees are good but only really with flat-plane crank
[15:48] <nigelvh> Yes, the horizontally imposed engines are really nice. Last forever.
[15:48] <gonzo_> V8 or broke!
[15:49] <_Hix> I'm 2 short of an 8
[15:49] <Upu> me too
[15:49] <_Hix> but it's in the right place :D
[15:49] <nigelvh> I'm 4 short of an 8, but I get 27 miles a gallon.
[15:49] <_Hix> 23 on a good day
[15:49] Action: Upu raises an eye brow
[15:50] <gonzo_> be honest, all my running ones are 4cyl these days
[15:50] <Upu> I get 55mph on a 3.0l V6
[15:50] <Upu> mpg
[15:50] <kokey> I've got a V6, 2.5L, which is big for the UK
[15:50] <_Hix> ha mph
[15:50] <gonzo_> I used to get 13mpg, on a run
[15:50] <kokey> and the V6 is the reason no one seems to want to replace the spark plugs
[15:50] <gonzo_> 7 around town
[15:50] <kokey> to get to the 3 on the one side you have to take lots of stuff off
[15:51] <nigelvh> I had a V6 in my ford ranger, and I got about 17-20mpg
[15:51] <_Hix> my engine is an arse to get to. It's pretty much inside the car
[15:52] <Lunar_LanderU> and nigelvh ...
[15:52] <Lunar_LanderU> what do you think about...
[15:52] <Lunar_LanderU> DMC-12 DeLorean?
[15:52] <daveake> kokey Yeah on my V6 there's 3 at the front - easy to get to, and 3 at the back, which are a PITA apparently
[15:52] <kokey> I don't know why everyone doesn't measure fuel economy in l/100km
[15:52] <gonzo_> my old triumph is best, whole bonnet/wings lift up and you can sit on the wheel to do work
[15:52] <kokey> I mean gallons are not even the same between countriexz
[15:52] <nigelvh> It's a neat idea. But they're expensive, and going to be a bitch for parts.
[15:52] <Dan-K2VOL> bah, go SI please
[15:52] <kokey> daveake: for sure, I checked the instructions and it involves taking off about 14 bolts, the manifold and lots of pipes
[15:53] <kokey> I thought I would do it myself with a spark plug spanner, could thing I read up on it first
[15:53] <Dan-K2VOL> kokey, if we're talking going to a better fuel economy, we ought to go to joules per km or something
[15:53] <gonzo_> we like to cling to the oldie-worldie units
[15:54] <kokey> could=good
[15:54] <nigelvh> See, my plugs are easy to get to, stick a plug socket on the end of an extension, stick em down in the engine, and pull em out.
[15:54] <nigelvh> I replaced mine last night
[15:54] <kokey> lucky you
[15:54] <_Hix> right gotta go - cheers again for the help guys :)
[15:54] <kokey> we were supposed to drive to my gf's folks this weekend, but I cancelled because I don't trust the car
[15:55] <nigelvh> That's always a tough spot
[15:55] <kokey> it's doing something funny and I want to make sure it's the spark plugs first and not something worse
[15:55] <kokey> it's doing something similar to a back-fire when coasting, when coming off the highway, but not exactly a back fire
[15:55] <gonzo_> my previous car was like that. But I had breakdown cover. So if we got half way, then the we would be towed the rest of the way
[15:56] <nigelvh> Yeah. That's kinda how I felt with my ranger vs my old car. Despite being from '84 and having nearly 300,000mi on it, I trusted the old car because I could make it run with duct tape and bailing wire. The '95 ford was all computerized, and if it broke i was hosed.
[15:56] <gonzo_> backfire through the exhause or carbs?
[15:56] <kokey> yeah I got break down cover but I want it to be in range for it to be towed home or a garage nearby, not a few hours away up country
[15:57] <nigelvh> I have AAA and they'll tow up to 100mi
[15:57] <kokey> gonzo_: well, it shudders, but I think the emissions control system prevents it from going bang
[15:57] <kokey> gonzo_: and the emissions control light comes on when it's happened
[15:57] <nigelvh> Hmmm....
[15:57] <kokey> but that's just me speculating really
[15:58] <kokey> it's doing it at the times I would have expected a backfire on an automatic if there was a timing issue or something
[15:58] <gonzo_> well backfire through the carb/inlet is electrics 99% of time
[15:58] <Lunar_LanderU> nigelvh: did you already answer my question :)?
[15:58] <kokey> exhaust backfire that is
[15:58] <Lunar_LanderU> did you mean the DeLorean with "neat idea"?
[15:58] <nigelvh> Yes
[15:58] <kokey> i suspect it's done 65k miles on its first set of spark plugs and it's also timing belt replacement time
[15:58] <Lunar_LanderU> :)
[15:59] <Lunar_LanderU> OK
[15:59] <Lunar_LanderU> gotta get home now
[15:59] <Lunar_LanderU> cu later maybe
[15:59] <nigelvh> Have fun
[15:59] <kokey> anyway, will have to see next week if new spark plugs and belts make the problems go away

[17:48] <GW8RAK> Apparently they make a huge difference for portable or field work. Same as tuning the antenna, but you tune the earth instead
[17:49] <F5MVO> evening all
[17:49] <Lunar_Lander> ah
[17:49] <Lunar_Lander> what does that mean exactly?
[17:52] <GW8RAK> For a ground plane type aerial to work, the active element induces a signal in the ground plane which is at earth potential. However just as an aerial can be at a different impedance to 50 ohms, so the earth can also exhibit inductance and capacitance.
[17:53] <GW8RAK> The ground tuner cancels out the inductance and/or capacitance to ensure that the earth currents are maximised.
[17:53] <Lunar_Lander> ah OK
[17:53] <GW8RAK> Bloody difficult to explain though.
[17:54] <Lunar_Lander> no problem
[17:54] <Lunar_Lander> I think I got what it is about
[17:54] <GW8RAK> The more I think about aerials, the more I'm convinced I know nothing about them.
[17:54] <russss> aerials are witchcraft, plain and simple.
[17:54] <Lunar_Lander> yea, there are actually big books on antenna theory
[17:55] <GW8RAK> From talking to a friend, he said that with 200W, the earth current can be mA normally, but can become Amps if the gorund is tuned.
[17:55] <GW8RAK> Ground.
[17:55] <GW8RAK> And he got from NW England to Australia on 500mW of SSB

[20:00] <NigeyS> is it failing to write cuddykid ?

[20:45] <eroomde> and there's a convenient control bunker asttached which will make a perfect tracking room
[20:45] <eroomde> big tv on the wall to display spacenear.us etc
[20:45] <NigeyS> hah awsome!!
[20:45] <daveake_> :)

[21:30] <NigeyS> woops
[21:30] <Lunar_Lander> yea
[21:30] <fsphil> that's my trick
[21:33] <Lunar_Lander> fsphil?
[21:35] <fsphil> buying things and losing them
[21:35] <navrac_> I just discovered that my wife thew out the cord for the payload as it looked messy....
[21:36] <nigelvh> YAY
[21:36] <NigeyS> lol!!
[21:36] Action: fsphil looks around his neat and tidy room
[21:36] <fsphil> * may or may not be true

[21:37] <NigeyS> neat and tidy, i think ure fibbing mr phil? :p
[21:37] <nigelvh> My lady says as long as the door to my office can shut, it can be as messy as I like.
[21:38] <Lunar_Lander> Doc Browns garage was messy too
[21:38] <nigelvh> You're hung up on this back to the future business today aren't you?
[21:38] <fsphil> I'm gonna have to dump a lot of this stuff
[21:38] <Lunar_Lander> xD a bit
[21:38] <Lunar_Lander> but I like the big bang theory too!
[21:39] <nigelvh> And I like cheesecake
[21:39] <fsphil> custard and apple tard. mmmm
[21:39] <NigeyS> no rasberry pie?:P

[21:39] <nigelvh> how's that for a pun

[21:40] <jonsowman> anyone feel like making some coloured marker dots for me
[21:40] Action: fsphil has florescent paint
[21:41] <navrac_> I'm hoping my flight on sunday lands in the sea so no-one gets to see the mess I made with the silicon sealant
[21:41] <jonsowman> http://hourly.cusf.co.uk/images/marker-sm-red.png
[21:41] <nigelvh> There are other downsides to landing in the sea...
[21:41] <jonsowman> 12 shades of this...
[21:43] <NigeyS> blimey thats small
[21:43] <staylo> twss
[21:43] <jonsowman> lol
[21:43] <jonsowman> NigeyS: gmaps scales it cleverly as you zoom in/out
[21:44] <NigeyS> ah
[21:44] <NigeyS> saves me getting the magnifying glass out lol
[21:44] <jonsowman> google maps is all very clever
[21:45] <NigeyS> yush, shame its not 100% free anymore though
[21:45] <jonsowman> yeah
[21:45] <NigeyS> thing is its a huge cash cow waiting to be milked
[21:45] <NigeyS> inevitible i guess
[21:46] <jonsowman> yeah
[21:47] <Lunar_Lander> what does it mean GMaps isn't free anymore
[21:51] <staylo> Lunar_Lander: They spent a few years encouraging third parties to incorporate it in their services using the API, now they've noticed it actually costs quite a lot and doesn't pull in much advertising, so they're gradually restricting its use
[21:52] <Lunar_Lander> so spacenear will shut down someday?
[21:53] <staylo> I think it's linked to the amount of traffic, so should be safe. Not sure, haven't googled for details :)

[22:02] <navrac_> couldnt work out how to put it on the ukhas calendar
[22:02] <navrac_> qualtex 36"
[22:02] <Upu> so its not going that high ?
[22:02] <cuddykid> I can crack out the yagi/stand and help track if we're short of trackers
[22:02] <navrac_> nope 5km at a guess
[22:02] <navrac_> but the upload tests have been very promising today
[22:03] <Upu> Not sure I'll be able to hear that
[22:03] <cuddykid> good stuff
[22:03] <Upu> was about to say I'm not sure I'm going to have time to build that circuit for Sunday
[22:03] <navrac_> I wish I'd gone for a bigger balloon now to give it a good test
[22:03] <Upu> was going to do it today but it all went pete tong
[22:03] <Upu> added that to the list on spacenear.us
[22:04] <Upu> the very long list
[22:04] <navrac_> I know the feelingb upu - I decided to cover the boards in silicon sealant this morning - big mistake
[22:05] <navrac_> I might have to launch at 10 to get top of the list!

[22:10] <NigeyS> hm
[22:10] <NigeyS> we need more frequencies!
[22:11] <fsphil> you should have a separate colour for the first and last one jonsowman, just so we know which way it's going
[22:11] <jonsowman> fsphil: yeah
[22:11] <NigeyS> purple!!!!!
[22:11] <Upu> one of these Ava2 boards is some how on 434.067
[22:11] <jonsowman> lol
[22:11] <NigeyS> upu, ats-1 is on 651.5 :|
[22:11] <Upu> dunno if I have a faulty NTX2 or a dodgy circuit
[22:11] <Upu> oh fair enough
[22:11] <jonsowman> fsphil: i'm bored of doing this for today, i'll do it another time :)
[22:11] <Upu> the board with the 650 on is 647.50
[22:11] <fsphil> haha
[22:11] <jonsowman> i also want to have a script that polls for new datasets on the NOAA server

[22:12] <Upu> navrac can I clear ozzie from the tracker ?
[22:12] <Upu> this is on a bench PSU atm
[22:13] <NigeyS> ahh
[22:13] <navrac_> yep its test data I forgot that fldigi reverts to online on startup so theres a lot of rubbish data
[22:21] <jonsowman> fsphil: you can pull the hourly changes in now if you want
[22:21] <jonsowman> it's stable i think
[22:22] <jonsowman> if it breaks, sorry :P
[22:22] <NigeyS> would that work for pico predictions jon ?
[22:23] <jonsowman> NigeyS: it uses the same predictor binary as the standalone predictor
[22:23] <jonsowman> do you use that for pico stuff?
[22:23] <fsphil> will do
[22:23] <NigeyS> yup, its fairly accurate to, but obv never been tested if it floats
[22:23] <jonsowman> NigeyS: in theory it should be the same then
[22:24] <jonsowman> it runs the same binary for every hour for the next 180 hours
[22:24] <jonsowman> and plots the locus
[22:24] <jonsowman> there's a lot of glue scripts and other rubbish but that's the gist of it
[22:24] <NigeyS> ah right, might be worth having a play then for the pico stuff
[22:24] <jonsowman> https://github.com/cuspaceflight/cusf-landing-prediction/
[22:25] <NigeyS> thankoo very much :D
[22:31] <navrac_> if it makes it easier I guess I can launch saturday if there are any trackers available at short notice - It depends whether I can get hold of jcoxon as he is near here and should get a better signal than me
