[07:20] <UpuWork> i think what we call a mozzie and what the australians call mozzies are different beasts
[07:20] <UpuWork> the ozzie ones would need a NOTAM to fly here
[07:20] <schofieldau> lmfao
[07:21] <Hix> oh and i found a uart converter http://goo.gl/zIujb 5v/3.3v :)

[07:23] <Hix> twas
[07:23] <fsphil> considering the size of the IC and the small USB plugs, we could probably stick USB directly onto the boards now :)
[07:24] <Hix> UpuWork, have you got an eagle library?
[07:24] <Hix> oh and i forgot about posting the MC55's up
[07:24] <Hix> I'll do that today

[08:18] <fsphil> not too much number10. I know it'll be FM so will need a fairly good antenna

[08:19] <number10> I'll have a look at the CUSF site i think cheers
[08:20] <craag> Did you say that the SSTV can be received with an FM rx?

[08:41] <UpuWork> is the RFM22B we use the RFM22B-433S2 ?

[09:09] <UpuWork> no such payload
[09:12] <ejcweb> Ok, that's strange. We'll be able to fix this before the launch. I don't have habhub rights to add payloads myself.

[09:46] <Dutch-Mill-mob> 434.075 is also a bit critical but works ...lets move to rfm22:-)
[09:47] <UpuWork> I have 25 RFM22B modules on order
[09:49] <Dutch-Mill-mob> How is it at the HABgreen ...ironing or chilling. in the sun?

[09:51] <gonzo_> wondering how feasable it would be to graft an IQ modulator into the TX path for an rfm22 ?
[09:51] <Dutch-Mill-mob> Have some Rfm 22 but need breakoutbords ..
[09:52] <navrac> 433.975 is terrible here
[09:53] <Bob_G8NSV> just trying to set mmsstv for loopback soundcard, cant find option to select card?
[09:54] <Laurenceb_> you know you can use si4432 - its the ic in the rfm22
[09:55] <Laurenceb_> ive said this before :P
[09:55] <Laurenceb_> theres si4467 now too
[09:55] <Laurenceb_> with a better lna iirc
[09:55] <navrac> yes - but 1) its tiny, 2) it needs a lot of matching components and a good pcb layout
[09:56] <navrac> wheras an rfm22 is just easy
[09:56] <Laurenceb_> true :P
[09:56] Action: Laurenceb_ -> off
[09:57] <navrac> but i must admit, i am tempted
[09:58] <gonzo_> There was a recent design using a U2793 , which would sit nicely after an rfm23 (or 22 with atten)
[09:58] <gonzo_> http://g0nzo.no-ip.com:8080/misc/radcom_iq/

[10:01] <Bob_G8NSV> will run 2 versions of fldigi one per rig different sound cards
[10:02] <Bob_G8NSV> will that confuse tracker?

[10:06] <navrac> isnt the nano 5v?
[10:07] <kokey> I'm still contemplating between using an MSP430 or a duino or sorts
[10:07] <Bob_G8NSV> 328 16mhz same as my duemilonove which I will use for development as I have an LCD and stuff on it that will be useful for debugging and other stuff (maybe!)
[10:08] <navrac> so you need to level convert for the rfm
[10:08] <Bob_G8NSV> it is I believe
[10:08] <Bob_G8NSV> downside there
[10:08] <Bob_G8NSV> extra messing
[10:08] <Jim3> does anyone know of a small(er) formfactor arduino Mega? would be really useful to get the extra hardware UART ports but the standard mega is soooo big.
[10:08] <Bob_G8NSV> not impossible
[10:09] <Darkside> Jim3: seeeduino mega
[10:09] <Darkside> its a bit shorter
[10:09] <Bob_G8NSV> easy on TX

[11:25] <ael> you can hear squirrel already?
[11:25] <G0DJA> LazyLeopard I gave up on the idea of 433.975MHz for that same reason

[11:25] <ael> oh i see
[11:25] <ael> sorry

[11:28] <ael> i cannot hear much on 975
[11:29] <ael> just qrn
[11:30] <LazyLeopard> No idea what it is, but it's sufficiently evenly periodic to be artificial. Suspect it'll cause too many errors for 50 baud RTTY to be any use.
[11:30] <G0DJA> Sounds like some sort of distributed data mode, like OLIVIA or something
[11:30] <LazyLeopard> Could be.
[11:31] <ael> either my setup is deaf or it's quite local to both of you. i am in a remote area
[11:31] <daveake> I'm hearing short bleeps at maybe 4 different frequencies. Same as you guys?
[11:31] <G0DJA> It's probably some MOD station complaining about the amount of RTTY they can hear above 434MHz
[11:31] <daveake> lol

[11:33] <daveake> 434.65 is clean aside from a tone on 434.650.75 which I always get

[11:35] <kokey> launching soon?
[11:35] <daveake> Rx Mode currently Auto
[11:36] <G0DJA> The tuning can be quite critical on SSTV - have you set up the 'slant' by monitoring WWV or one of the Russian frequency standards?
[11:36] <daveake> Nope
[11:36] <daveake> Never done this before
[11:36] <daveake> Guide somewhere?
[11:37] <G0DJA> If not set MMSSTV to record the audio (I think it can do that) and then play it through again when you have the slant corrected
[11:37] <daveake> ok will do

[11:39] <kokey> got to love this on the SSTV article in Wikipedia: "Not to be confused with SS-TV, an SS organization responsible for administering concentration camps during WWII."
[11:39] <daveake> The guide suggests that auto slant is the work of the devil :)

[12:08] <G0DJA> If he was using it I'd still hear him and if I wanted to squelch him out it still wouldn't work when I went to USB
[12:09] <LazyLeopard> Ah. So chances are he's listening somewhere further up...
[12:09] <G0DJA> No, down 1.6MHz
[12:09] <LazyLeopard> ...and wouldn't hear anything hat came back at him on .650 anyway.
[12:09] <G0DJA> 433.050 will be the output freq
[12:10] <G0DJA> True but once a conversation starts he'll be TXing every few minutes
[12:11] <G0DJA> Here's a map of the UK repeaters that use 434.650 as their input frequency http://www.ukrepeater.net/channels/rb02.htm
[12:11] <pjm> afternoon all, is there anything up at the moment?
[12:11] <G0DJA> So it's surprising we don't get more problems I guess
[12:11] <G0DJA> Not that has been anounced yet pjm
[12:11] <ael> pjm - 'fairly soon' 1hr ago
[12:13] <mfa298> I'm not sure many people use 70cms repeaters. 70cms as an amateur band seems fairly dead down here most of the time unless something big is on.
[12:13] <ael> I recall the one in cambridge was often active
[12:13] <ael> GB3PY
[12:13] <pjm> tnx, i will go to background
[12:13] <G0DJA> mfa298 I used to prefer it when out mobile over the 2M repeaters - with a decent antenna and about 25W there's reasonably good coverage across the UK
[12:14] <LazyLeopard> GB3LS Lincoln, then...
[12:15] <mfa298> I'm sure there used to be more activity but that was probably back in the days of the old novice license.
[12:15] <G0DJA> There's a local repeater on 433.200/434.800MHz but far enough away to not be a problem on 650
[12:15] <G0DJA> I've used VHF/UHF more than HF even since getting a G0

[12:18] <G0DJA> Given where GB3CI and GB3AV are I'm surprised more of the 434.650 payloads have not run into problems
[12:19] <G0DJA> It's one of the reasons I went for a 434.075MHz TX - No repeaters on that freq
[12:21] <LazyLeopard> I guess it only bothers trackers living inside the relevant coverage areas. As luck would have it I'm outside both GB3LV and GB3NX coverage.
[12:21] <G0DJA> OK time for one more cuppa then collect Kate
[12:22] <G0DJA> At the heights the balloons get to I'm surprised more repeaters dont suffer from noises being transmitted through them if people 'blip' them up when a RTTY signal is on

[13:40] <Andy-g0poy> Most of the blips and other QRM are caused by the small wireless transmitters in keyfobe, weatherstations and whatever is aroung you.

[13:50] <Wouter-[pa3weg]> hi
[13:51] <Graham_G3VZV> its ok - I wont tell:)
[13:51] <G0DJA> No, that's even further off the advertised settings...
[13:51] <Andy-g0poy> I find that a little DSP noise reductioin helps Rx - using the IC910 here

[13:54] <Andy-g0poy> JOEY signal is very low now, I expect that it is out of the lobes of the antenna, as it is quite close to me, and now vert high up.
[13:54] <futurity> on the dl-fldigi, is it best to have solid yellow lines with yellow speckled dots, or faint yellow lines and no speckled dots?

[13:56] <gonzo_> beware of using DSP on data rx. You can get away with it at low baudrate rtty but can cause problems on other modes

[15:15] <Andy-g0poy> On Wombat 50bd try a wider Rx filter bandwidth, I've got mine set to 329 that seems to help with the initial decode.

[15:26] <Upu_2E0UPU> sorta
[15:27] <LazyL_M0LEP> Unconvinced here. Bandwidth helps a bit provided it's not too wide.
[15:27] <Andy-g0poy> The wider rx filter on wombat 50 helps a little here , but something it does not decode. Looking at things carefully, it seems to start decoding OK at the first figure of the sequence number.

[15:30] <LazyL_M0LEP> I found 50 got worse when I opened the bandwidth past about 150. Increased the chances of catching the QRM I think...

[15:31] <Wouter-[pa3weg]> for me both 300 and 50 wombat are fine
[15:32] <ael> so instead of $$$$$WOMBAT,xxx you get something like vmxxx
[15:32] <Randomskk> interesting, maybe longer preamble on 50 would be better
[15:32] <Randomskk> right I see
[15:32] <Randomskk> at least you can in theory get a position I guess
[15:32] <Randomskk> wow I'm glad it worked at all >_>
[15:32] <Randomskk> had to swap batteries at the last minute
[15:32] <Randomskk> so this was a lipo
[15:32] <Randomskk> rather than the lithium AAs it was going to use

[15:34] <ael> was it fine and dandy?
[15:35] <ael> blimey astra really is suffering
[15:35] <kokey> will nexus be recovered?
[15:35] <Randomskk> don't know yet
[15:35] <Randomskk> no word from it
[15:35] <navrac> i could trace joey to almost ground level - but the qrm meant i couldnt get a comple sentence to upload - once char always missing
[15:35] <ael> that's what happens with burst i guess
[15:35] <kokey> oh, nevermind
[15:35] <NickB1> looks like astra lost lock ?
[15:35] <ael> so nova22 is on its way down now
[15:35] <Randomskk> oh I see that tweeet

[15:38] <LazyL_M0LEP> Signal strength is up, and 300 wombat comes through quite well at present.

[15:38] <Randomskk> yea, intentionally
[15:38] <Randomskk> I wanted to see if it helped or hindered
[15:38] <Upu_2E0UPU> but the missing the first few chars is a problem
[15:38] <Randomskk> yea that seems to be the biggest issue
[15:38] <ael> and again

[15:38] <Randomskk> hmm
[15:39] <Randomskk> Upu_2E0UPU: does it look like the ends are mostly good, just the first few?
[15:39] <LazyL_M0LEP> The extra wide shift works, but makes frequency control a bit more critical.

[15:41] <LazyL_M0LEP> The frequency tracking settings I have in dl-fldigi don't cope with the wide shift, so it needs more babysitting.

[15:42] <Upu> QRM on that probably AEL
[15:42] <Randomskk> LazyL_M0LEP: you can increase fldigi's waterfall bandwidth up to 4khz
[15:42] <Randomskk> do you generally think the shift is too big?

[16:50] <r2x0t> also decoder performance isn't that good

[17:27] <eroomde> he has an 857, i have my ic-7000
[17:27] <Randomskk> heh
[17:27] <Randomskk> how'd the icom perform?
[17:27] <eroomde> we used s splitter to combine them to a signle colinear
[17:27] <domlin> me and ooda55 are looking to send a balloon up soon :) currently looking for a helium supplier...
[17:27] <eroomde> so we could do wombat+astra/joey+nexus simulteranously

[17:27] <Randomskk> oh nice
[17:28] <eroomde> the icom is great
[17:28] <Randomskk> I still keep finding new things to do with it
[17:28] <OZ1SKY_Brian> hi
[17:28] <eroomde> i was fighting like a mad thing with the bandwidth filters and notch filters to try and get rid of some of the crap
[17:28] <eroomde> the bandwidth in the end was about 50hz wider than the spacing so i was constantly returning
[17:29] <eroomde> but the sound card on the old p4 box i was using is a pile of shit
[17:29] <eroomde> i could take the line-in jack out and the waterfall would still be speckly yellow
[17:30] <eroomde> just from internal emi
[17:30] <eroomde> so am gonna get a decent external one for next time
[17:30] <Randomskk> I have an external USB sound card with a line in for this now
[17:30] <eroomde> mba doesn't have linein either
[17:30] <eroomde> annoyingly
[17:30] <Randomskk> yea very
[17:30] <Randomskk> hence my having the external really
[17:30] <Randomskk> it barely has mic in
[17:30] <Randomskk> annoying
[17:32] <eroomde> yeah
[17:32] jonquark (jonl@nat/ibm/x-pgnuyidbntyrfgsh) left irc: Remote host closed the connection
[17:32] <eroomde> still, i'm happy with today. good first step towards setting up a permenant listening post
[17:32] <Randomskk> pretty nice
[17:32] <domlin> where do you guys normaly get helium from?
[17:33] <eroomde> we get ours from BOC but that's an atypical arranagement
[17:33] <eroomde> 'we' = not me anymore really, but cusf
[17:34] <SpeedEvil> http://www.cs.cmu.edu/afs/cs.cmu.edu/user/mnr/st/std147 - ... Search for 'dense Propellants'
[17:34] <domlin> aha i did speak to boc earlier, they quoted us something like £90
[17:34] <eroomde> for what?
[17:34] <priyesh> try Air Products too - apex have used them before we started using BOC
[17:34] <domlin> a T cylinder
[17:35] <eroomde> ouch
[17:35] <domlin> but a friend owns a card/party warehouse and he has a lot of helium all the time, hopefully hes a good bet
[17:36] <eroomde> make sure it's pure
[17:36] <eroomde> sometimes you get balloon helium which is like 40% air
[17:36] <eroomde> that's not good for hab
[17:37] <domlin> yeah i was told about that
[17:37] <domlin> i think he gets it from boc anyway
[17:37] <eroomde> ok
[17:37] <eroomde> sounds promising
[17:37] <domlin> fingers crossed :)

[17:39] <fsphil-laptop> boc's balloon gas is 95% helium
[17:39] <fsphil-laptop> or so they say
[17:39] <SpeedEvil> Above is recommended reading - with excerpts from 'ignition' and other books
[17:39] <eroomde> ?
[17:39] <eroomde> wrong channel?
[17:40] <eroomde> tho 'Ignition!' is a wonderful book
[17:40] <SpeedEvil> Well - sort-of, I suppose
[17:40] <eroomde> if it's the one i think you're talking about
[17:40] <SpeedEvil> But a number of people here are interested in rocketry
[17:40] <SpeedEvil> And it is high altitude :)
[17:42] <ooda55> How's the chase for Astra and Joey going?
[17:42] <Randomskk> both recovered
[17:42] <Randomskk> and wombat and squirrel
[17:42] <Randomskk> jonsowman's driving back to cambridge with them now
[17:42] <Randomskk> while the launch team siti in a pub :P
[17:42] <ooda55> Ah great news it didnt land in the sea, im guessing they cut the payload down
[17:43] <Randomskk> nah, just got a bit lucky
[17:43] <Randomskk> no cutdowns
[17:43] <ooda55> Haha me and Domlin were hoping to join them for the launch but could'nt make it :(
[17:44] <ooda55> Very lucky indeed, so they have been having TX/RX problems with the online tracking?
[17:44] <Randomskk> mostly okay
[17:44] <Randomskk> squirrel stopped working but joey was okay
[17:45] <Randomskk> though hard
[17:45] <eroomde> it was odd today
[17:45] <Randomskk> astra lost lock but wombat was fine
[17:45] <eroomde> there was lots of interference
[17:45] <Randomskk> but yea looks like there was a lot of intereference etc
[17:45] <eroomde> about one giant fart per packet
[17:45] <eroomde> which would frequently null the whole thing
[17:45] <Randomskk> :|
[17:45] <priyesh> Randomskk: did wombat ever interfere with astra>
[17:45] <eroomde> oh Randomskk i found that the ic-7000 could cope with the farts if you put the agc into fast mode
[17:45] <Randomskk> doesn't appear to
[17:45] <eroomde> AGC-F
[17:45] <Randomskk> eroomde: nice
[17:45] <Randomskk> yea I leave it in that all the time anyway
[17:46] <Randomskk> though I've swapped slow for X for when I want to turn it off
[17:46] <eroomde> as it quickly recovered after the huge burp of rf down to the weak signals of the payload and if you were lucky it'd be ok
[17:46] <eroomde> something to remember
[17:47] <number10> Randomskk: what was the transmitter in Wombat?
[17:47] <Randomskk> adf7012
[17:47] <number10> very stable
[17:47] <fsphil-laptop> rtty+convolution coding .. although one works with bytes and the other bits
[17:47] <Randomskk> yea the problem is to do useful coding we need to drop rtty
[17:47] <fsphil-laptop> totally
[17:47] <Randomskk> using rs232 start and stop bits is kinda silly
[17:48] <eroomde> yeah wombat was nice and stable
[17:48] <eroomde> the most stable of the day
[17:48] <number10> even with the QRM was able to decode
[17:48] <eroomde> astra was charging up and down the spectrum like an F1 car
[17:48] <Randomskk> number10: http://www.flickr.com/photos/cuspaceflight/6962972965/in/set-72157629171748600/
[17:48] <eroomde> joey was fine too
[17:48] <Randomskk> wombat was encased in foam
[17:48] <Randomskk> it should have been v happy
[17:48] <number10> very nice board Randomskk
[17:48] <Randomskk> though its freq stability is good anyway
[17:49] <Randomskk> right bbl
[17:49] <fsphil-laptop> the big capacitor looks like a face with a tear
[17:49] <number10> I could receive Joey down to very low altitude but QRM corrupted decodes
[17:51] <ooda55> Is there a reason you guys use 430MHZ comms instead of GPS/GSM trackers?
[17:51] <eroomde> GSM doesn't work about [arguement]m
[17:52] <eroomde> where arguement could be 200m, but if i say that i'll start an argument
[17:52] <eroomde> someone's mum once skydived backwards from the moon and managed to send a text from 92km
[17:52] <domlin> orly?
[17:52] <eroomde> bob's light aeroplane caused a lensing effect with a gravitation wave that gave him 3G at 35,000ft
[17:52] <eroomde> or something
[17:52] <eroomde> but basically gsm stops working at a comparatively low altitude
[17:53] <domlin> however, it works in planes when in cruise...
[17:53] <ooda55> Haha okay i see, well we were planning to use a GPS tracker along with a simple RF beacon an yagi antenna setup
[17:53] <domlin> passenger aircraft i mean
[17:53] <eroomde> gsm helpful ion ground
[17:53] <eroomde> but rf is fun
[17:54] <domlin> fair enough :)
[17:55] <eroomde> in other news, running several instances of dl-fldigi at once seemed to be fine
[17:55] <eroomde> 2 per channel
[17:55] <eroomde> each channel having a 300 baud and a 50baud one

[18:45] <nigelvh_> Yep
[18:45] <domlin> ive done a lot of stuff with arduino, that might come in handy :)
[18:45] <domlin> however - the first experience me and ooda55 had with mixing 433mhz and arduino lead to a large failure
[18:45] Dan-K2VOL (~Dan-K2VOL@fw.pilosoft.com) left irc: Ping timeout: 252 seconds
[18:46] <nigelvh_> Yeah. Most of the time, I'll design a board, and use the same chips as the arduinos on it.
[18:46] <domlin> because we were driving 2 large dirty motors which made more interference than i can even imagine
[18:46] <nigelvh_> However, the arduino board itself isn't terribly interference resistant.
[18:47] <nigelvh_> I'd guess mostly because of the wires coming off the board connecting it to everything else.

[18:48] <nigelvh_> A proper board with routed connections and nice ground planes does much better.
[18:48] <domlin> yeah we did a lot of research after and found a lot of tips... but never got round to altering it
[18:48] <nigelvh_> I run 434 on my telemetry systems at about 500mW and never have an issue.
[18:48] <ooda55> Isnt that about 490ma over the legal limit? :P

[18:49] <domlin> it was originally a 2.4GHz wifi controlled robot, which you can see on instructables ;)

[18:50] <domlin> i'd like to get into long long distance 433 transmission
[18:50] <Morseman> Now, why was it transmitting on 433.200MHz?
[18:51] <nigelvh_> IE from a baloon?
[18:51] heathkid (~heathkid@unaffiliated/heathkid) left irc: Ping timeout: 250 seconds
[18:51] <domlin> yeah
[18:51] <domlin> is the NTX2 a good choice?
[18:51] <domlin> we currently have a cheap TX and RX kit
[18:51] <Upu> its a good choice, well tested
[18:52] <ooda55> Any cheaper alternatives you can reccomend?
[18:52] <nigelvh_> Well, all these kind folks in the have a good bit of experience with the low power transmitters in the UK
[18:52] <Upu> cheaper than NTX2 ? not going to get much cheaper really
[18:52] <nigelvh_> I have the joy of lording my 500mW transmitters over them.
[18:52] <Upu> RFM22B is slightly cheaper
[18:52] <Morseman> domlin CW is a good mode - in good conditions can make 1000km or more from here
[18:53] <Upu> if you want a cheap NTX2 PM me
[18:53] <domlin> *awfully dumb question altert* Morseman... whats CW?
[18:53] <nigelvh_> Morse code
[18:53] <Upu> carrier wave i.e morse
[18:53] <nigelvh_> (Carrier Wave)
[18:53] <Morseman> Continuous Wave - In other words Morse Code
[18:53] <Upu> I thought it was carrier too ?
[18:53] <domlin> yay now i know :)
[18:53] <nigelvh_> I've heard it both
[18:53] <ooda55> *alert
[18:53] <domlin> fu
[18:54] <Morseman> nigelvh could be - some people say one others the other
[18:54] <Morseman> You say tomato and you say tomato
[18:54] <nigelvh_> Carrier makes more sense to me since it's an unmodulated carrier
[18:54] <Morseman> Sorry - too many 'you' in that
[18:54] <nigelvh_> wheras continuous would make more sense as a never ending transmission, whereas CW is full of dits and dahs
[18:55] <domlin> would you say the RFM22B is a better choice purely because it can transmit and recieve?
[18:55] <Morseman> Wiki says carrier is a part of continuous wave ;-)
[18:55] <nigelvh_> A good number of people don't recieve at the baloon
[18:55] <Morseman> http://en.wikipedia.org/wiki/Continuous_wave
[18:55] <Upu> well depends if you want to receive
[18:55] <Upu> most people just transmit
[18:55] <nigelvh_> I don't.
[18:56] <Upu> and balloons receiving hasn't been well tested
[18:56] <nigelvh_> TX only from my baloons.
[18:56] <Morseman> Now now Upu - some of us use break in as well...
[18:56] <LazyL_M0LEP> Of course, the one thing morse isn't is continuous. ;)
[18:56] <Morseman> That's listening between characters - full break in is listening between dashes and dots...
[18:57] <Upu> glad you clarified :)
[18:57] <Morseman> LazyL some beacons use a form of Morse where there's a mark and a space so continuous...
[18:57] <nigelvh_> I don't really do any morse code, so doesn't matter too much to me.

[19:20] <nigelvh_> We've done crickets
[19:20] <Upu> yes I said ignore the sketch
[19:21] <RocketBoy> its got the ntx2 at the wrog end
[19:21] <Upu> in fact its about time I fixed it
[19:21] <Upu> I know
[19:21] <Upu> I'll fix it 1 sec
[19:21] <RocketBoy> its about time you fixed that
[19:21] <Upu> lol
[19:21] <Upu> we ordered our gas
[19:21] <RocketBoy> ive taken mine back
[19:22] <domlin> nigelvh_: did they survive?
[19:22] <number10> all on for staturday then Upu :)
[19:22] <Upu> yup
[19:22] <Upu> well what I don't use is going straight back on Monday
[19:22] <daveake> Just need to get the bacon and rolls in :)
[19:22] <nigelvh_> No. These were random students. They thought they might survive in a plastic watter bottle
[19:23] <domlin> oh dear :(
[19:23] <pjm> i wonder if there would be any advantage to trying a vertical antenna with a bit of gain, something like 1/4 over 5/8 for UHF, i guess u want radiation out the sides mostly as the balloon will be low down on the horizon for most people
[19:23] <nigelvh_> Yeah, we have a rule with the class that if they want to try, they can fly bugs. Nothing with fur.
[19:23] <number10> send some out to trackers daveake
[19:24] <daveake> :D
[19:24] <domlin> nigelvh_: sounds like a good rule
[19:24] <nigelvh_> Yeah...
[19:24] <domlin> snake it is then
[19:24] <nigelvh_> That would probably be vetoed.
[19:25] <domlin> understandable...
[19:25] <nigelvh_> We summarize the rule with "nothing with fur" but reserve the right to veto.
[19:25] <nigelvh_> is a better description.
[19:25] <domlin> haha ok :)
[19:25] <nigelvh_> Also nothing that explodes, and no flame.
[19:26] <Upu> http://ava.upuaut.net/files/qua_wave.jpg
[19:26] <RocketBoy> pjm: if you are talking about the UK434MHz then technically if you increase the gain beyond a dipole you will need to cut the power back to retain the same 10dBm erp level
[19:26] <domlin> no overclocking the atmel's then?
[19:26] <nigelvh_> Also, no really loud shit. The students invariably turn it on like an hour before launch and decides to kill our ears.
[19:26] <pjm> RocketBoy ahh i didnt realise there was an eirp limit - although in reality, i wonder who would ever check
[19:26] <nigelvh_> Someone wanna fly a 1.5KW amp? I'm game!
[19:27] <domlin> what do you mean by loud shit? like radio equipment?
[19:27] <ooda55> If your paying!
[19:27] <nigelvh_> Like buzzers and attempting to measure the speed of sound
[19:27] <domlin> ahh ok
[19:28] <nigelvh_> ooda55: all you gotta do is supply the amp and the helium, and the balloon, and the batteries. I'll take care of breakfast and the launch site.
[19:28] <RocketBoy> pjm yeah - but everyone wants to be squeeky clean right - and the range records become a bit meaningless if everyone starts to run more
[19:28] <ooda55> I do like breakfast ;)
[19:28] <nigelvh_> daveake has the right idea with feeding his slaves breakfast.
[19:29] <pjm> RocketBoy ahh ok on the squeeky clean, understandable i spose
[19:29] <domlin> is there a launch on saturday?
[19:29] <pjm> also is that 10dBm peak power or average?
[19:30] <pjm> if its average, u could happily run 13dBm at 50% duty and still be 'legal'
[19:30] <daveake> domlin Upu and I are launching 2 balloons from Berks
[19:30] <daveake> The SHARP team may also be launching.

[19:31] <navrac> peak
[19:31] <nigelvh_> Average over what time span?
[19:31] <pjm> exactly...
[19:31] <nigelvh_> Yeah, mine averages 0dBm over a year.

[19:31] <navrac> at asny point in time....

[19:32] <daveake> got it right 2nd time
[19:32] <domlin> wow
[19:32] <RocketBoy> yeah its a transmit power output level - not a measurement of absorbed poer
[19:33] <domlin> there's so many great sites for all this
[19:33] <domlin> i guess i am used to the mini forum though...
[19:34] <RocketBoy> IR2030 is the spec to read if you want the letter of the regs

[19:37] <domlin> look reallllly stupid question... has anyone ever put anything in with the gas into the balloon? like confetti?
[19:37] <Upu> James May put pet ashes in
[19:37] <daveake> or ashes ...............
[19:38] <domlin> wow
[19:38] <Upu> you could see them when it burst too
[19:39] <domlin> ha thats really cool... im surprised i haven't seen a program about that i watch all of james may's stuff :(

[19:41] <Lunar_Lander> :)
[19:41] <domlin> hello there :) thank you!
[19:41] <Lunar_Lander> you're welcome?
[19:41] <domlin> i popped on yesterday to ask a few questions and everyone seems very lovely so have stayed
[19:41] <Upu> lol
[19:41] <Lunar_Lander> there is one question I ask everyone new I see
[19:41] <Lunar_Lander> xD
[19:41] <Lunar_Lander> US, UK, Australia, other country?
[19:42] <domlin> UK
[19:42] <Lunar_Lander> ah
[19:42] <domlin> along with ooda55, we're going to be launching a balloon in the near future
[19:42] <Lunar_Lander> germany here
[19:42] <Lunar_Lander> cool
[19:43] <domlin> ah very nice
[19:43] <ooda55> Anyone here rockin a RepRap?
[19:44] <Upu> can you translate ?
[19:45] <domlin> I think he mean "does anyone here own a 3D printer?"
[19:45] <Upu> oh
[19:46] <Upu> I own a bench saw and a router which are technically old school 3D printers
[19:46] <Laurenceb_> hehe
[19:47] <domlin> ha
[19:47] <Laurenceb_> 3D printers are for noobs
[19:47] <Lunar_Lander> XD Upu
[19:49] <ooda55> Well looks like i just got owned there
[19:51] <Lunar_Lander> I think all printers today are 3D printers, and those so called 3D printers are 4D printers
[19:52] <Lunar_Lander> printing takes time
[19:52] <Lunar_Lander> so that adds one more dimension to the spatial dimensions
[19:52] <Lunar_Lander> XD
[19:52] <mfa298> Upu: nice one :D

[19:58] <Lunar_Lander> can you paint stainless steel?

[20:28] <Lunar_Lander> cool
[20:28] <nigelvh> This last one may end up making the transision to the dreaded title of "wife" one of these days.
[20:29] <navrac> and dont particulray go looking for one - it will make you nervous - the right one will come along at the right time

[20:52] <Lunar_Lander> thanks
[20:53] <griffonbot> @PD3EM: I've ordered some more electronic parts tonight. Still busy developping a #HAB beacon that will be into near space later this year #ukhas [http://twitter.com/PD3EM/status/185107452449132544]
[20:54] <Lunar_Lander> cool
[20:55] <navrac> if you send the ublox - 0xB5, 0x62, 0x06, 0x24, 0x00, 0x00, 0x2A, 0x84
[20:55] <navrac> it will reply with a byte which tells you what mode its in
[20:56] <navrac> well it will reply with a string of bytes - the 8th one is the mode
[20:57] <Lunar_Lander> ah
[20:57] <Lunar_Lander> thanks
[20:59] <navrac> what do you mean by mode though? powersaving type mode or airbourne type mode
[21:00] <Lunar_Lander> if it is in airborne mode or not
[21:00] <navrac> then thats the right string and byte to look for
[21:00] <Lunar_Lander> yea
[21:00] <Lunar_Lander> thanks :)
[21:00] <Lunar_Lander> what will it say if in airborne mode?
[21:01] <Lunar_Lander> ah
[21:01] <Lunar_Lander> if(bytePos == 8){
[21:01] <Lunar_Lander> navmode = b;
[21:01] <Lunar_Lander> return true;

[22:13] <Matt_soton> so HF transmitter anyone?
[22:13] <Laurenceb_> PBH crashed and sank then?
[22:16] <NigeyS> laurenceb Gobbled up by the sea monsters
[22:16] <NigeyS> Matt_soton, dont think anyone managed to track via hf
[22:17] <Matt_soton> we managed to get it in the car with the 2/70 whip, so im guessing out of noone being around rather then trying andd failing?
[22:18] <NigeyS> yeah think it was just a case of not many have a hf setup
[22:18] <Matt_soton> also if we had internet i could have got people to try with their UHF setup
[22:18] <Randomskk> the ft817 can do it on a 2m whip :P
[22:18] <Matt_soton> we tracked and recovered two payloads with no internet
[22:18] <Matt_soton> no spacenear
[22:18] <NigeyS> meh i only got a 790 :(
[22:18] <Matt_soton> just on recieved signals
[22:19] <Randomskk> Matt_soton: well, and the gsm tracker :P
[22:19] <NigeyS> good work!!
[22:19] <Matt_soton> although gsm backup confirmed the second one
[22:19] <Matt_soton> we got a packet at 390 m
[22:19] <Matt_soton> we didnt need gsm
[22:19] <Randomskk> fair enough
[22:19] <Matt_soton> but it confirmed
[22:19] <NigeyS> any idea what was up with squirrel ?
[22:19] <Matt_soton> and we wouldnt have wwanted to fly without it
[22:19] <Randomskk> apparently wombat stopped jon locking his car when they parked to go find it
[22:19] <NigeyS> haha
[22:19] <Matt_soton> nope not yet, ed is currently in bed i espect
[22:20] Jasperw (~jasperw@93-97-176-250.zone5.bethere.co.uk) joined #highaltitude.
[22:20] <Matt_soton> im suprised you managed to decode it so low when we were near by and had so many issues
[22:20] <NigeyS> how is heating it btw? noticed the temp at 7k was 40c :|
[22:20] <NigeyS> he*
[22:20] <Matt_soton> very well insulated
[22:20] <Matt_soton> and L1 had cameras
[22:20] <NigeyS> ahh that'll explain it
[22:20] <NigeyS> ok dumb question ..
[22:20] <Randomskk> the cameras did really well
[22:20] <Randomskk> when we turned them off at 8.30pm
[22:21] <Randomskk> 100% battery, SD cards slowly still filling up
[22:21] <Matt_soton> i tihnk astra just has a dodgy GPS, it was only really to geenrate RTTY for he HF anyway
[22:21] <NigeyS> got 2 rolls of gaffa tape for outside of picochus insulation, grey and black, black should in theory keep it warmer right ?
[22:21] <Randomskk> in theory
[22:21] <Randomskk> not convinced it'd make a huge amount of difference though
[22:21] <Randomskk> get some foam
[22:21] <Matt_soton> wombats insulation was really quite ott
[22:21] <Randomskk> haha you say that
[22:22] <Randomskk> I think it was just right :P
[22:22] <NigeyS> same thinking here, have foam, and bubblewrap, usual stuff i use, but i norm give it a coat of gaffa tape aswell
[22:22] <Randomskk> fair enough
[22:23] <Randomskk> it's slightly non obvious I think because while black will absorb heat better
[22:23] <Randomskk> it will also radiate better
[22:23] <Randomskk> I think the answer might actually be complicated
[22:23] <Randomskk> but to be honest the difference is probably negligable for this
[22:23] <NigeyS> good point
[22:23] <NigeyS> hopefully this 1 gets a bit higher than 889m :p
[22:24] <Randomskk> :P
[22:24] <NigeyS> rain + gales + pico = bad
[22:25] <NigeyS> also Randomskk the result of your help last night .. $$SWIFT,205,546505817,-67479749,74674 :-)
[22:25] <Randomskk> :D
[22:26] <NigeyS> made so many of those silly mistakes last night, should code when tired really :/
[22:26] <SpeedEvil> Black tape and grey tape will be essentially identical in terms of longwave IR radiation.
[22:26] <NigeyS> shouldnt*

[22:26] <SpeedEvil> I could actually test this, with my IR thermometer in the kitchen, and a bit of geometry, but can't be arsed.
[22:27] <NigeyS> SpeedEvil, had a feeling that was the case, as Adam says any difference would be negligeable if any at all

[22:27] <NigeyS> lol
[22:27] <SpeedEvil> I did quite a bit of research into finding non-fake 'thermal insulator' paints
[22:27] <SpeedEvil> There have been research projects into doing low-E paints - in short - it's hard.
[22:27] <NigeyS> i bet
[22:28] <SpeedEvil> IIRC the best was something like anodised Ti flake - to get 'green' - in a LDPE binder.
[22:28] <NigeyS> im surprised at the lack of drift on this ntx2 mind, covered the xtal in hot glue, and some foat, and ive not had to move the tuning dial in a good hour
[22:29] <SpeedEvil> :)
[22:29] <NigeyS> anodised ti flake .. that sounds interesting!
[22:29] <SpeedEvil> I wonder if a largish portion isn't somehow differntial heating
[22:29] <SpeedEvil> due to airflow

[22:30] <NigeyS> hm, possibly
[22:30] <SpeedEvil> Which most insulation measures will of course sort
[22:30] <NigeyS> this has been rock solid since i moved it to the garden, no insulation other than foam on the ntx2, from 24c to 12c and not a single hint of drift
[22:31] <SpeedEvil> Ice cube time?
[22:31] <Elwell> well, that's ATV-3 nigh on docked
[22:31] <NigeyS> SpeedEvil, done that already, but not with the foam, i cant put it in the freezer now as the antenna radials are soldered on, verrrrrrry fragile :/
[22:31] <jonsowman> good evening all
[22:31] <NigeyS> hey jonsowman, great busy day!!
[22:32] <SpeedEvil> Ah
[22:32] <SpeedEvil> jonsowman: hey
[22:32] <jonsowman> only just got home... left at 7am this morning...
[22:32] <jonsowman> lol
[22:32] <NigeyS> bloody eck :o
[22:32] <NigeyS> you'll sleep tonight! lol
[22:32] <jonsowman> ah well, all went pretty well!
[22:32] <NigeyS> so did joey perform as good as appeared ?
[22:32] <Matt_soton> astra needs a new gos
[22:32] <Matt_soton> gps
[22:32] <Matt_soton> look how far it wondered from wombat to start with
[22:33] <jonsowman> NigeyS: apparently some QRM problems since it was in the 433.9x range
[22:33] <jonsowman> but we decoded it fine
[22:33] <NigeyS> qrm was insane, even here
[22:33] <jonsowman> we got basically every packet
[22:33] <jonsowman> /nearly/ saw it land
[22:33] <Matt_soton> and some in the 434.000 range, but they were self inflicted
[22:33] <NigeyS> excellent!!!
[22:33] <Morseman> Didn't decode anything at all here I'm sorry to say
[22:34] <NigeyS> brb time to bring picochu in
[22:34] <jonsowman> :)
[22:34] <Morseman> Not SSTV nor RTTY
[22:34] <jonsowman> thanks for trying Morseman
[22:35] <Morseman> I did see 'stuff' but nothing decoded to the point where it was accepted by the upload system anyway
[22:35] <jonsowman> spacenear looks amazing right now

[22:36] <Matt_soton> its a shame noone tried the HF, even with UHF antennas :(
[22:36] <jonsowman> we were getting 20dB+ SNR in the car with the whip
[22:36] <jonsowman> but we were out in the middle of nowhere
[22:36] <Matt_soton> got 30 at one point...
[22:37] <jonsowman> Matt_soton: can i have the joey telem log please?
[22:37] <Matt_soton> as in fldigis output?
[22:37] <jonsowman> yeah
[22:37] <Randomskk> everything everyone else got is on habitat
[22:37] <SpeedEvil> Hmm. Should the tracks of the balloons be the same colour as their payload?

[22:37] <jonsowman> Randomskk: yeah, but chase car stuff isnt
[22:37] <SpeedEvil> Wombats track looks orange - but the balloon is yellow
[22:37] <mfa298> I had my radio tuned in for the HF but wasn't hearing anything (I didn't expect to - bad location)

[22:38] <Morseman> Yes LazyLeopard similar here
[22:38] <Randomskk> SpeedEvil: hmm.. I think yellow is darkened a bit to make it show up better on the map
[22:38] <Matt_soton> well thanks for trying mfa298
[22:38] <griffonbot> @cuspaceflight: Thanks to all who helped with the Nova 21 and Nova 22 launches and tracking today. Pictures & videos to come soon. #cusf #ukhas [http://twitter.com/cuspaceflight/status/185133905702170628]
[22:39] <SpeedEvil> http://www.mauve.plus.com/womb.png
[22:39] <mfa298> if it had been a non work day I might have had better luck as I could either have stuck the antenna out the window or gone out mobile somewhere.
[22:39] <Morseman> Matt_sotton I tried with a horizontal HF antenna - My 11M vertical mag mount was inside so not able to try it
[22:39] <SpeedEvil> yeah - I guess the others are somewhat different too - it's just it's most striking with yellow
[22:39] <Matt_soton> jonsowman: http://pastie.org/3688411 enjoy
[22:40] <jonsowman> thanks Matt_soton
[22:40] <Matt_soton> hmm probably the wrong day then
[22:40] <mfa298> I think there were a few people that wanted to try the HF tracking but things went against them.
[22:41] <Matt_soton> even though we wer eusing a VHF/UHF antenna, we were quite close
[22:41] <mfa298> craag was going to have a go but found the radio he has wouldn't do that frequency
[22:41] <Morseman> I did hear a single tone on 27.124MHz but no RTTY
[22:41] <jonsowman> yeah we heard that
[22:41] <Matt_soton> but we had good signal so someone else should have been able to hear
[22:41] <jonsowman> random carrier on 27.1 ish
[22:41] <Matt_soton> we heard a carrier nearby, too
[22:42] <Matt_soton> but the transmitter would have been rtty, and a slightly differnet freq
