[04:52] <SamSilver> Java time
[04:53] <SamSilver> 06h53 local
[04:53] <Zuph> I could use some coffee, actually.
[04:53] <Zuph> :-P
[04:53] <SamSilver> do you know who is launching next?
[04:54] <SamSilver> Whats your local time?
[04:55] <Zuph> 0054
[04:55] <SamSilver> what is keeping you up? Python?
[04:58] <Zuph> Masters Thesis
[04:59] <SamSilver> related to ARHAB?
[04:59] <Zuph> Not in the least!
[05:00] <Zuph> Got back from antenna testing about an hour ago, though. Finally some good results there. Looks like white star is flying a J-pole!
[05:00] <SamSilver> :-o
[05:00] <SamSilver> the jpole is for sat recieving
[05:00] <SamSilver> and down link aswell
[05:01] <SamSilver> ?
[05:02] <Zuph> Yep
[05:02] <Zuph> We tested it tonight, and couldn't stop the thing from getting data out!
[05:02] <SamSilver> great!
[05:02] <SamSilver> next is the weather
[05:13] <natrium42> weather is definitely out there
[05:15] <SamSilver> weather not as easy as a Jpole to get right
[05:15] <SamSilver> but it is weather that will provide WhiteStar with legs to cross a bit of water

[09:49] <MrCraig> What's wrong with wales?
[09:49] <MrCraig> hehe
[09:50] <MrCraig> Is there anything you can do to counter an undesirable prediction fsphil? Could you slightly over or under inflate to affect ascent/descent?

[12:10] <NigelMoby> Also jruby
[12:10] <fsphil> if you can modify NewSoftSerial itself then it would be trivial to stop the interrupt from doing anything during the rtty bit

[12:11] <fsphil> power drain?

[12:11] <Laurenceb_> that will end badly
[12:12] <NigelMoby> Pain in the rear end when using a lassen
[12:12] <Laurenceb_> you are trying to run uart to gps ?
[12:13] <NigelMoby> Yer Phil, wild fluctuations .. between 2.6 and 3.1v
[12:13] <NigelMoby> Yup Laurence.
[12:13] <fsphil> oh, the voltage will vary
[12:13] <fsphil> at the TX pin
[12:13] <Laurenceb_> so hw uart to gps, then what?
[12:14] <fsphil> ooh you're not actually transmitting anything with nss
[12:14] <NigelMoby> Tis fine with h/w Nss gives garbled rtty
[12:14] <Laurenceb_> rtty from the avr?
[12:14] <NigelMoby> Nip, only rxing
[12:15] <NigelMoby> Yer laurence, very frustrating
[12:15] <Laurenceb_> can you describe what you are trying to do?
[12:15] <Laurenceb_> gps -> uart then io pin - ntx2 ?
[12:16] <NigelMoby> Tx the gps data over software serial to the avr.
[12:16] <Laurenceb_> why cant you use the uart to get the gps data?
[12:17] <NigelMoby> In use, I need uarts atmega328 has 1
[12:17] <NigelMoby> 2*
[12:17] <Laurenceb_> what is the second uart used for?
[12:17] <Laurenceb_> i think you need a better micro
[12:18] <NigelMoby> Ftdi to the pc, when that's not connected I need it for the t68
[12:18] <Laurenceb_> 344 or whatever its called
[12:18] <Laurenceb_> http://www.avrfreaks.net/index.php?module=Freaks%20Devices&func=displayDev&objectid=104
[12:19] <NigelMoby> If I can't fix it I will have to get 1 with 2
[12:20] <NigelMoby> Ooo looks like it'll do the job.
[12:20] <NigelMoby> Hey ed
[12:20] <eroomde> curses
[12:20] <eroomde> hey NigelMoby
[12:21] <NigelMoby> Hihi
[12:21] <eroomde> how's it going?
[12:21] <NigelMoby> Eugh ok I guess and you?
[12:23] <eroomde> not bad thanks
[12:24] <Laurenceb_> if you had the baud rate of the software usart a multiple of the rtty, say 50baud rtty and 300baud serial
[12:24] <Laurenceb_> it may be possible
[12:24] <eroomde> lovely day out, have made the transition to shorts now uintil about october
[12:24] <Laurenceb_> dunno how fast you need it
[12:25] <Laurenceb_> bit banging a uart is _hard_
[12:25] <Laurenceb_> when other stuff needs tro be done
[12:26] <Laurenceb_> ti68 is 9600 iirc
[12:26] <NigelMoby> Hmm ill bit bang it with a hammer soon!
[12:26] <Laurenceb_> and lassen 4800?
[12:26] <Laurenceb_> lol
[12:26] <NigelMoby> Yups
[12:26] <Laurenceb_> 4800 interrupts/second is a lot
[12:26] <eroomde> NigelMoby: are you out of UARTS?
[12:27] <eroomde> UARTs*
[12:27] <Laurenceb_> as a rule of thumb, 100 clk overhead for servicing a isr on avr
[12:27] <Laurenceb_> so ~500000clk/sec
[12:27] <NigelMoby> Yup and Nss is garbling rtty
[12:27] <Laurenceb_> guess thats not the end of the world
[12:28] <Laurenceb_> so timer isr at 4.8khz may help
[12:28] <eroomde> NigelMoby: what hardware are you using currently/
[12:28] <eroomde> ?
[12:28] <NigelMoby> Hmm I see the problem
[12:28] <eroomde> must learn to touch type ^
[12:28] <Laurenceb_> it sets the bit banged uart tx appropriately and the rtty pin
[12:28] <NigelMoby> Atmega328 and lassen iq ed
[12:29] <Laurenceb_> can you reset the lassen iq to 9600 baud?
[12:29] <NigelMoby> Ahh so its a game of timer fiddling?
[12:29] <Laurenceb_> then you could use the rx and tx of one uart for phone and lassen
[12:29] <Laurenceb_> maybe
[12:29] <Laurenceb_> ^what about that?
[12:29] <NigelMoby> Actually I'm not sure, quite possibly via tsip
[12:29] <Laurenceb_> oh you can
[12:30] <Laurenceb_> but is that good enough - no feedback from phone
[12:31] <Laurenceb_> guess the phone either sends the sms or it fails, so...
[12:31] <NigelMoby> I'll try it soon as I get on the desktop
[12:31] <Laurenceb_> +CMS ERROR: 500
[12:31] <eroomde> get a bigger chip
[12:31] <Laurenceb_> youll learn to love that
[12:31] <eroomde> my helpful advice of the day
[12:31] <eroomde> i'll get back to work now
[12:31] <Laurenceb_> atmega324
[12:32] <NigelMoby> I noticed Jgraham had same prob but his lassen was at 9600
[12:32] <Laurenceb_> if you take that route
[12:32] <NigelMoby> Lol ya ed
[12:32] Action: Laurenceb_ gets back to work too
[12:32] <NigelMoby> Ta*
[12:33] <NigelMoby> I'll give suggestions a try, tnx Laurence

[13:33] <SamSilver> rtty the flavour of the month I see
[13:33] <NigeyS> ops -M
[13:34] <fsphil> rtty is easy with the modules
[13:34] <fsphil> easiest digital mode anyway
[13:35] <SamSilver> CW slow but good range
[13:35] <fsphil> it's a bit of a fuzzy mode
[13:35] <eroomde> rtty is the flavour of the last couple of years. it's very easy and works well with computers
[13:36] <eroomde> CW isn't all that efficient either
[13:36] <eroomde> but it suits human ears
[13:37] <SamSilver> I have been reading up about QRP super slow
[13:37] <SamSilver> 3 seconds for a dit

[13:38] <griffonbot> Received email: Ed Moore <eam52@cam.ac.uk> "Re: [UKHAS] Balloon RS92SGP from CRANFIELD touchdown BRAINTREE"
[13:38] <eroomde> still, when you are constrained in with bandwidth or power, there are more efficient things than CW in both
[13:39] <SamSilver> 1300 miles on 160milliwatts
[13:39] <eroomde> SamSilver: a local ham did transatlantic cw on 10mW
[13:39] <eroomde> that was quite impressive
[13:39] <NigeyS> WHAT?! 10mw ? :o
[13:39] <SamSilver> I am thinking CW for my long duration flouter
[13:40] <eroomde> i think it's probably the thing to go for from the point of view of getting lots of hams with HF rigs to listen in
[13:40] <eroomde> but probably not the thing to go for from a pure engineering eprspective

[14:32] <eroomde> it allows them to pay for machines on research grants which usually preclude buying computers
[14:32] <eroomde> grants are quite stupid. often they don't pay tax, so they basically only pay for 80% of anything
[14:33] <eroomde> and they won't pay for desks or computers or things like that, as if they are meant to just already exist by magic

[17:29] <fsphil> I'll see what I can do ;)
[17:30] <TangoAlpha> what sort of payload weight should I be aiming for?
[17:30] <fsphil> light as you can I suppose
[17:31] <fsphil> brb
[17:31] <TangoAlpha> lol
[17:31] <TangoAlpha> i've just weighed most of the bits and it's 1750 grmas
[17:31] <TangoAlpha> grams even
[17:31] <TangoAlpha> given the table on ukhas.org.uk, that's a bit overwieght
[17:32] <TangoAlpha> who keeps switching the keys around on my keyboard
[17:36] Action: fsphil whistles innocently
[17:36] <fsphil> that is pretty heavy
[17:36] <fsphil> what's in it?
[17:36] <Zuph> space bricks
[17:36] <Zuph> Sorry, *near* space bricks
[17:36] <TangoAlpha> an anchor for when it lands
[17:36] <TangoAlpha> http://weeble.ath.cx/projects/balloon/
[17:38] <TangoAlpha> i can lose 200/300 grams without much problem
[17:39] <Zuph> That's quite a bit!
[17:39] <MrCraig> Liking the online spreadsheet
[17:40] <TangoAlpha> i haven't calibrated my scales...he says hopefully
[17:40] <x-f> TangoAlpha, how many times did you change your projects title? :)
[17:40] <TangoAlpha> hehe
[17:40] <TangoAlpha> every time i thought of a good one, someone else had already taken it
[17:41] <TangoAlpha> i think i'm on number 3 or 4
[17:41] <fsphil> do you need such a big battery?
[17:41] <TangoAlpha> probably not
[17:42] <TangoAlpha> i haven't tested the flight computer fully yet
[17:42] <TangoAlpha> it was something i had for another project
[17:43] <TangoAlpha> i have a much smaller one at 61 grams
[17:43] <fsphil> the hand warmer might not be needed either
[17:44] <TangoAlpha> that was just an idea, i think my polystyrene box will be good enough not to need heating
[17:44] <fsphil> indeed
[17:44] <fsphil> esp. with two cameras in there
[17:44] <TangoAlpha> my smaller battery is 2200mAh which i guess will be enough
[17:45] <fsphil> you're far too well organised
[17:45] <fsphil> :p
[17:45] <TangoAlpha> my thinking with 2 cameras was that I was going to get a wider range of view if I took shots from both sides
[17:45] <TangoAlpha> :-p
[17:46] <fsphil> the box will normally be spinning so one camera could in theory get shots from all directions
[17:46] <TangoAlpha> two cameras was more "insurance" against one not owrking, the payload not spinning...etc.
[17:46] Action: MrCraig sets ISO as high as possible and hopes for the best.

[17:46] <fsphil> good idea
[17:47] <MrCraig> I had wanted to put a swivel in the line to minimise any spin transferred from the balloon or cord, but time defeats.
[17:47] <TangoAlpha> does anyone have suggestion for camera settings? or is it just use auto with no flash?
[17:47] <MrCraig> I'm off to pack the car, I'll be online again tomorrow sometime from site.

[17:48] <TangoAlpha> shame, too far away really
[17:48] <fsphil> Weather's to be nice tomorrow so I'm heading up the mountain with the yagi for a bit of tracking
[17:49] <TangoAlpha> mountain?
[17:49] <fsphil> Yea, I've a small mountain about 10km north of where I live
[17:49] <fsphil> about 400m high
[17:49] <TangoAlpha> lol
[17:49] <fsphil> more a big hill to be honest
[17:50] <Zuph> hah, 400m :-p
[17:50] <fsphil> yea yea, you and your big mountain ranges :p
[17:50] <TangoAlpha> i can't think of anywhere within 50 miles of me that could be considered more than a small hill
[17:52] <fsphil> nice flat horizon then, good for radio :)

[17:56] <fsphil> lol yes - he seems to get rather intimate with them
[17:56] <stilldavid> we always launch when the wind blows toward the plains, though :)
[17:56] <stilldavid> though a backcountry trip for recovery sounds like it could be fun!
[17:57] <fsphil> would be a hell of a recovery though
[17:57] <stilldavid> make a week(end) out of it
[17:57] <Zuph> Dan tells a story about a balloon they lost in the Smokeys.
[17:57] <fsphil> *hmm.. the payload has stopped at 1km...*

[17:58] <Zuph> Local ham group took it upon themselves to recover the payload. Had the local fire department drive up a narrow, steep fire trail, and cut down like 2 dozen trees :-p
[17:58] <fsphil> not sure stilldavid, it keeps appearing on there
[17:58] <stilldavid> heh, at what point do you have to consider the environmental impact of your project?
[17:59] <fsphil> nooo that's bad!
[17:59] <Zuph> If it were up to Dan, he'd have just left the thing in the tree
[17:59] <Zuph> Hams will be hams, though.
[18:00] <fsphil> reminds me, must charge the yaesu' battery
[18:01] <stilldavid> and that reminds me, I need a new one!
[18:01] <fsphil> that's right
[18:01] Action: stilldavid googles for one less than $65 USD
[18:01] <Zuph> I'll be on the Balloon Panel at the Dayton Hamvention this year, btw.
[18:02] <fsphil> you could probably make a nice portable external battery

[18:02] <fsphil> something that fits onto the 817 in some way
[18:02] <stilldavid> I like the idea of it being handheld still
[18:02] <stilldavid> oh, yes. and I now remember that I keep forgetting to see if I have the AA bracket
[18:03] <Zuph> I need to unlock my Wouxun
[18:04] <fsphil> that sounds fun
[18:04] <stilldavid> I wound up on the panel for: http://spacegrant.colorado.edu/symposium/papers_for_review.html
[18:04] <stilldavid> not sure how that happened :-/
[18:04] <fsphil> the 817 can be unlocked too but it involves soldering
[18:05] <Zuph> Wouxun is just a software thing, afaik
[18:05] <Zuph> I'm really enjoying my $100 chinese HT

[20:01] <Lunar_Lander> ""The men working on the balloon must need to be very careful not to punch a hole in the polyethylene," ventured Charles Thomas, who possesses a card-index mind accustomed to probing for details.
[20:01] <Lunar_Lander> "Oh, we can't trust men for this job," Vera Winzen remarked blithely. "It is something only women can do. I get a little jumpy even when my husband starts handling the balloon while it's being inflated. There's something feminine about a balloon through and through, and that's why most of them are named after women." Turning in my direction, she said that it was up to me to name the balloons of the forthcoming flights. "

[20:05] <NigeyS> hey phil
[20:05] <NigeyS> you got that monster powered up yet ?
[20:05] <fsphil> no psu to run it yet
[20:05] <fsphil> typically
[20:06] <NigeyS> ah dam :(
[20:06] <fsphil> might be able to borrow one to test
[20:06] <NigeyS> you getting up for the apex launch ?
[20:06] <fsphil> that's the plan atm
[20:06] <NigeyS> snap, left mums retirement party early so i could get some kip
[20:06] <fsphil> so early night tonight!
[20:07] <NigeyS> im resisting opening the payload box, if i do that ill start working on the nss problem and before i know it it'll be 3am again :/
[20:08] <NigeyS> ping natrium42
[20:08] <fsphil> lol - have that
[20:09] <NigeyS> tnx for the help last night btw, think you'd gone to bed before i left
[20:09] <fsphil> if you can compile nss yourself, instead of using the supplied version, you can fix it pretty quickly
[20:09] <NigeyS> well i downloaded a newer version that seems to include that missing avr file
[20:09] <NigeyS> im wondering though if its just a case of not having the nss.end in the right place
[20:10] <fsphil> did you put it before the rtty bit?
[20:10] SpikeUK_ (~chatzilla@pdpc/supporter/monthlybyte/spikeuk) joined #highaltitude.
[20:11] <NigeyS> yeah and after, but if you look at my further up the script i have rtty_send(Starting test bla); wondering if i need it there aswell, as that sentence was also undecodeable with nss enabled
[20:11] <fsphil> yep

[20:11] <DanielRichman> ^^ this is why we used an avr with two usarts
[20:12] <NigeyS> either that or its to do with the new millisecond timer stuff added in for the gps lock LED
[20:12] <fsphil> basically the nss interrupt is doing too much work, making your own programs timing go all nuts
[20:12] <DanielRichman> it was rediculously oversized for the project and there was about 20 unused gpios
[20:12] <DanielRichman> but it has 2 usarts ;P
[20:12] <fsphil> lol
[20:12] <NigeyS> DanielRichman, wish i had now, btw i have the t68i working perfectly!
[20:12] <DanielRichman> :-)
[20:12] <DanielRichman> you used https://github.com/danielrichman/alien/blob/master/misc-c/arduino-168/at-sms.c iirc?
[20:12] <NigeyS> many thanks for the work you put in with the arduino ver of the code, made it much simpler for an idiot like me lol
[20:12] <NigeyS> yups
[20:12] <DanielRichman> did it require any modifications?
[20:13] <NigeyS> only because i was using nss
[20:13] <DanielRichman> ok, cool :-)
[20:13] <NigeyS> and that was to specify which pin was rx, and which was tx, so not to overvolt the phone
[20:14] <NigeyS> are you ok with me having the sms code in my github? i've left in the credits for you and the alien team etc
[20:14] <DanielRichman> yeah it's fine
[20:14] <NigeyS> oki, cheers, i remembered to remove my phone number!
[20:15] <DanielRichman> it's gpl'd which means you are allowed -- and I can't prevent you :P -- sharing it provided the gpl is kept

[21:04] <NigeyS> good luck for the exams Upu :-)
[21:04] <Upu> cheers
[21:04] <andrew_apex> good luck with it Upu
[21:04] <NigeyS> which 1 is it upu ?
[21:04] <Upu> I can leave the radio on
[21:04] <Upu> Foundation and Intermediate
[21:04] <NigeyS> oo 2 in 1, nicey

[21:28] <Lunar_Lander> ohh look: http://en.wikipedia.org/wiki/Balloon_flower
[21:34] <fsphil> I prefer the MI6 callsign to 2I0 .. it's easier to say!
[21:36] <mattltm> Got your new one issued fsphil?
[21:36] <fsphil> yep
[21:36] <mattltm> Good job :)
[21:37] <fsphil> still used the MI6 on the last contest -- figured no point, only using 5W :)
[21:37] Action: NigeyS bitchslaps nss
[21:37] <fsphil> half way saving up for the big radio
[21:37] <mattltm> What you getting?
[21:38] <fsphil> ft857d
[21:38] <mattltm> Good choice :)
[21:39] <fsphil> yep -- of all the rigs it seems the best choice
[21:39] <fsphil> basically a more powerful 817
[21:40] <mattltm> And an interesting wideband mod too :)
[21:41] <fsphil> software mod? the 817nd needs a bit of soldering
[21:41] <mattltm> Is a jumper mod :9
[21:41] <mattltm> And you loose the ARS feature.
[21:43] <mattltm> Ok, so I have the GPS feeings lat/long/alt into an arduino...
[21:43] <mattltm> and I have a pan servo that takes 0 - 360 input to put it into postition
[21:44] <mattltm> and a tilt servo that takes 0 - 90
[21:45] <mattltm> Just need to work out how to rip the payload data from dl-fldigi
[21:45] <mattltm> and turn that payload lat/long/alt into servo commands.
[21:45] <fsphil> you're driving the servo from the ground?
[21:46] <mattltm> Yup.
[21:46] <fsphil> aah
[21:46] <fsphil> the payload spin might be too fast for you to aim it at anything in particular
[21:47] <mattltm> so the idea is to recive the payload signal, feed into dl-fldigi, decode, get the payload lat/long/alt from dl-fldigi, feed to arduino and move the pan/tilt head to point that the payload.
[21:47] MoALTz (~no@92.9.78.94) left irc: Quit: Leaving
[21:47] <mattltm> *point at the payload
[21:47] <fsphil> aaah
[21:47] <mattltm> so the yagi is always following the flight.
[21:47] <fsphil> for some reason my brain assumed the servos where on the payload
[21:48] <mattltm> Now that would be cool :)
[21:48] <fsphil> very lol
[21:48] <fsphil> you could implement an xmlrpc command for reading the last valid fields
[21:48] <fsphil> or entire string
[21:49] Action: NigeyS blames matt
[21:50] <mattltm> Getting just the needed info would be best. But how do I get that from Dl-Fldigi?
[21:50] Action: mattltm dosen't care.
[21:50] Action: mattltm slaps NigeyS around a bit with a large trout
[21:50] <NigeyS> haha biatch :P
[21:51] <fsphil> you can't at the moment
[21:51] <mattltm> fsphil: I know :(
[21:51] <Lunar_Lander> btw
[21:51] <Lunar_Lander> do you know Gerald Bull?
[21:51] <fsphil> well, you can get a copy of the received text window
[21:51] <Upu> well good luck with the launch, I've left the radio on
[21:51] <Upu> night all
[21:51] <Lunar_Lander> night Upu
[21:51] <fsphil> g'night Upu!
[21:51] <mattltm> night Upu
[21:52] <fsphil> but you'd have to search the text window and do all the crc stuff yourself. which isn't too bad tbh
[21:52] <mattltm> Im thinking that I could hardcode a fixed point into the code and move the unit around to test.
[21:53] <fsphil> are you able to build dl-fldigi?
[21:54] <mattltm> Not at the moment.
[21:54] <mattltm> Next week I could.

[21:55] <fsphil> wouldn't be too difficult to add the 'last valid string' command
[21:55] <jonsowman> nearly ready with apex, setting off soon!

[21:56] <jonsowman> I've slept all day, my body clock is messed up but I'm so awake :o
[21:57] <Lunar_Lander> jonsowman
[21:57] <Lunar_Lander> Apex III?
[21:57] <jonsowman> Lunar_Lander:
[21:57] <jonsowman> Apex II
[21:57] <Lunar_Lander> ah
[21:57] <jonsowman> but second launch, same payload :)
[21:57] Action: NigeyS is yet to get to bed!
[21:57] <jonsowman> well, with a few modifications
[21:57] <Lunar_Lander> ah, so Apex II B?
[21:58] <jonsowman> Lunar_Lander: indeed
[21:58] <fsphil> Apex II2 :)
[21:58] <Lunar_Lander> xD
[21:58] <fsphil> Apex II2 beta
[21:58] <jonsowman> that's just silly :P

[22:12] <Lunar_Lander> anyways

[22:12] <Lunar_Lander> he always referred to the coast as to "The Wash"
[22:12] <Lunar_Lander> xD
[22:13] <jonsowman> The Wash is the name for the estuary on the East Anglian coast afaik

[22:32] <natrium42> everybody still being awesome? :)
[22:32] <Lunar_Lander> yeah
[22:32] <Lunar_Lander> I just wanted to tell something funny
[22:32] <MNSP> rhetorical question?
[22:33] <Lunar_Lander> I was calculating ascent speed with newtonian drag at high altitude
[22:33] <Lunar_Lander> for a balloon i mean
[22:33] <Lunar_Lander> and just for the fun of it, I replaced newtonian drag with Stoke's drag, which is only good for like small spheres
[22:33] <Lunar_Lander> and I got an ascent rate of 144 km/s
[22:33] <Lunar_Lander> xD
[22:34] <MNSP> lol, you know only round here do I hear people say these things
[22:35] <SpeedEvil> LOL.
[22:36] <natrium42> hehe
[22:37] <natrium42> so, launches tomorrow?
[22:37] <MNSP> 2 woohoo
[22:37] <Laurenceb> $%^
[22:37] <natrium42> what bothers you, laurence?
[22:37] <Laurenceb> gerbmerge cant merge layers
[22:38] <natrium42> eek
[22:38] <Laurenceb> after i spent the last half an hour writing a config file :S
[22:38] <natrium42> can't you just concat the files?
[22:38] <Laurenceb> im going to have to do this by hand or write my own script
[22:38] <Laurenceb> no, the element names clash
[22:38] <natrium42> aah, eek
[22:39] <Laurenceb> i need to rename them and declare them in the appropriate places
[22:39] <Laurenceb> then concat the exposure coordinate lists
[22:40] <Laurenceb> i need different layers from multiple boards to end up one one layer of my panel
[22:41] <Laurenceb> seems gerbmerge isnt that clever, it can only panelise a single board
[22:41] <Laurenceb> not mix and mash up multiple boards that you only have in gerber form
[22:42] <Laurenceb> i could do this in inkscape if i had a way to get back to gerber from DXF or SVG

[23:37] <Dan-K2VOL> ?
[23:37] <NigeyS> 4800
[23:37] <Dan-K2VOL> sounds like a docile rate

[23:38] <Dan-K2VOL> have you tried the opposite inversion?

[23:38] <NigeyS> ive tried everything short of throwing a hammer at it
[23:39] <Shuffty> Hey nigeys - are you sending a text from the atmega to the phone directly, or through another phone?
[23:39] <NigeyS> directly from the avr
[23:39] <NigeyS> eventually itll pull the lat/lon from the gps
[23:39] <NigeyS> rather than helo world haha
[23:40] <Shuffty> lol... and then send it out via sms rather than display it as a new recieved sms?
[23:40] <NigeyS> yups
[23:41] <Dan-K2VOL> NigeyS are you sending or receiving serial? is it from the GPS?
[23:41] <NigeyS> from the gps, so sending only
[23:41] <NigeyS> actually reverse that .. you get what i mean..lol
[23:42] <NigeyS> nss is recieving from the gps
[23:42] <NigeyS> Shuffty, i only had my contract sim handy thats why ive got the sms on the t68 and not my own mobile
[23:44] <Shuffty> :-)
[23:44] <Shuffty> so you sent it out and back to yourself?
[23:44] <NigeyS> yups
[23:44] <NigeyS> codes in my github
