[11:08] <rharrison_> I'm going to launch a radio beacon in the next two days. It won't do much other than transmit UKHAS in morse code. Anyone facy listening?
[11:14] <gordonjcp> yeah, ok
[11:14] <gordonjcp> cw or audio morse?
[11:18] <rharrison_> audo morse
[11:18] <rharrison_> audio
[11:18] <rharrison_> but you can use cwget to decode
[11:19] <rharrison_> I'm going to use the helium I have left from the last w/e to send up the transmitter
[11:19] <rharrison_> Will send it up real slow so it will end up far away
[11:21] <gordonjcp> ok
[11:21] <gordonjcp> where are you launching from?
[11:21] Action: gordonjcp is quite far north
[11:22] <gordonjcp> also bear in mind that I'm at work during the day
[11:22] <rharrison_> Leeds
[11:22] <rharrison_> Me too
[11:22] <gordonjcp> oh ok, quite a bit closer
[11:22] <rharrison_> Will be evening
[11:22] <gordonjcp> when were you planning on launching?
[11:22] <gordonjcp> right
[11:22] <rharrison_> Probably Thursday night
[11:22] <gordonjcp> well let me know and I'll break out the yagi ;-)
[11:23] <rharrison_> 434.650
[11:23] <gordonjcp> wonder if you could fly a crossband repeater?

[14:03] <jcoxon> gordonjcp: thanks
[14:04] <jcoxon> hmmmmm
[14:05] <jcoxon> a repeater would be a cool experiment
[14:05] <jcoxon> perhaps even do:
[14:05] <jcoxon> earth - balloon -- balloon - earth
[14:06] <jcoxon> would be pretty hard to do
[14:06] <jcoxon> but very cool
[14:06] <SpikeUK> Don't mess about! earth - balloon - moon - earth ;-)
[14:07] <jcoxon> if you can't hear a beacon though we could still try one way comms as you could use a lot more power to reach the balloon then the balloon can do to you
[14:08] <jcoxon> SpikeUK: haha
[14:08] <SpikeUK> jcoxon - it'll need more than a monopole though :-0
[14:10] <jcoxon> we could use the balloon as a reflector dish
[14:10] <jcoxon> line the bottom half with something metalic
[14:10] <jcoxon> :-D
[14:11] <SpikeUK> Wrong shape? Need a paraboloid really
[14:14] <jcoxon> good point
[14:15] <jcoxon> oh well :-)
[14:17] <SpikeUK> jcoxon: I know you guys use metallised mylar - how about corner reflector inside the balloon?
[14:20] <jcoxon> could be done
[14:20] <jcoxon> right i better be off

[18:55] <natrium42> i couldn't test it much

[18:56] <EI5GTB> we'll start a balooning nety
[18:56] <natrium42> sure thing, i will try

[18:57] <natrium42> lol
[18:57] <EI5GTB> haha, the terminoligy can be un nerving allright
[18:57] <natrium42> i also saw the icom 756 pro iii
[18:57] <EI5GTB> :O
[18:57] <natrium42> it has an eccellent live spectrum display
[18:57] <natrium42> *excellent even
[18:58] <natrium42> but at that price, i would probably go with SDR
[18:58] <natrium42> Flex-5000A

[19:06] <EI5GTB> http://paulsnet.org/shack1.jpg
[19:09] <edmoore> what am I looking at?
[19:11] <EI5GTB> a computerscreen with a rainfall radar and aprs map
[19:11] <EI5GTB> a haf radio
[19:12] <EI5GTB> and a vhf radio
[19:12] <edmoore> ah so aprs is the cunning bit
[19:13] <EI5GTB> heh, spose so
[19:13] <edmoore> was wondering what those sites were
[19:13] <edmoore> well, not cunning, I mean the bit i couldn't figure out
[19:14] <EI5GTB> heh
[19:14] <EI5GTB> i have a dedicated monitor
[19:14] <EI5GTB> for it
[19:14] <EI5GTB> pointless, but looks neat
[19:14] <natrium42> EI5GTB, can i tune a wire antenna using regular ATU?
[19:14] <EI5GTB> if its earthed well
[19:15] <natrium42> hmm?
[19:15] <natrium42> so what's the difference to a wire antenna tuner?
[19:16] <EI5GTB> welll... a wire antenna can be anything from an inverted v dipole to a longwire
[19:16] <EI5GTB> i misread that
[19:16] <EI5GTB> an atu will tune a wire antenna......
[19:16] <natrium42> which antenna should i get for HF?
[19:16] <EI5GTB> what bands?
[19:16] <natrium42> let's say 20m, 40m
[19:17] <natrium42> but others too, if possible
[19:17] <gordonjcp> natrium42: receiving or transmitting>
[19:17] <gordonjcp> ?
[19:18] <natrium42> receiving, mainly
[19:18] <natrium42> at least for now
[19:19] <EI5GTB> for reciving, to be honest, a longwire would be grand
[19:19] <natrium42> vertical?
[19:19] <EI5GTB> for transmitting you would wnt a balanced dipole
[19:19] <gordonjcp> natrium42: long wire will do
[19:19] <EI5GTB> just a centre fed dipol is perfect
[19:20] <natrium42> does it have to be vertical to the ground or slanted?
[19:21] <EI5GTB> depends how aquward you want to be
[19:21] <EI5GTB> for a long wire
[19:21] <EI5GTB> luying on the ground would nearly work
[19:21] <EI5GTB> but generally just paralell top the ground
[19:21] <EI5GTB> at as high as possible
[19:22] <natrium42> but wouldn't vertical be more omnidirectional?
[19:23] <EI5GTB> yes
[19:23] <EI5GTB> but less practical
[19:24] <EI5GTB> and you need a decent groundplane then
[19:24] <natrium42> ah, ok
[19:25] <natrium42> so horizontal doesn't require a ground plane?
[19:25] <EI5GTB> nope
[19:26] <natrium42> do you know whether ATU is required for receive?
[19:26] <EI5GTB> it would help
[19:26] <EI5GTB> but it isnt a necesety, no
[19:26] <EI5GTB> for tx, eiter you use well tuned antennas or an atu
[19:26] <natrium42> right, cool
[19:26] <natrium42> thanks for the info
[19:26] <EI5GTB> np
[19:27] <natrium42> i think i will get the IC-7000 tomorrow
[19:27] <EI5GTB> :O
[19:27] <EI5GTB> i can has?
[19:27] <natrium42> what's your opinion of it?
[19:27] <natrium42> decent to start with?
[19:28] <EI5GTB> if i started with the ic-7000 id be....wow
[19:28] <EI5GTB> i started with a banger of a rig
[19:28] <EI5GTB> a sommercamp ft-767
[19:28] <EI5GTB> takes half an hor to become frequencxy stable..
[19:28] <EI5GTB> etc.. etc...
[19:28] <natrium42> hehe
[19:28] <EI5GTB> some days it dont work, you have to hit it
[19:29] <EI5GTB> other days it wont display the operating freq
[19:30] <natrium42> i have been tempted by HF-only radios
[19:31] <EI5GTB> well, vhfs can be picked up for cherap
[19:31] <natrium42> but perhaps it's best for me to have access to most HAM bands at the beginning
[19:31] <EI5GTB> but remember, if the hf radio goes down.. that means no vhf
[19:31] <natrium42> right
[19:32] <EI5GTB> thats my attitude, dont put all your wggs in one basket
[19:32] <natrium42> right
[19:32] <natrium42> i was thinking about the 756 pro iii
[19:32] <natrium42> but maybe an SDR is a better way to go
[19:32] <natrium42> once i am ready
[19:32] <EI5GTB> hmm
[19:32] <EI5GTB> possibly
[19:32] <EI5GTB> im not too well up on sdr as of yet
[19:33] <natrium42> my concern with the flex-5000 is that it seems to have poor sensitivity
[19:33] <natrium42> http://www.sherweng.com/table.html
[19:33] <natrium42> or am i misinterpreting?
[19:44] <gordonjcp> natrium42: I can thoroughly recommend the Jingtong JT-308 as a good way to get started on 70cms
[19:44] <gordonjcp> it's a bit crap but it's 15 quid
[19:45] <gordonjcp> turns out mine doesn't send CTCSS tones (or, doesn't send them correctly) but that's ok, I learned to whistle 1750Hz
[19:45] <natrium42> hehe, nice
[19:50] <jnd> someone should update the topic :p
[19:50] <gordonjcp> they also do the JT-208 which is the same but on 144MHz

[20:08] <edmoore> i only start seeing it working once it's a bitstream :)
[20:08] <edmoore> I asked on hamradio yesterday about building a simple narrowband 434 rx
[20:09] <edmoore> usually it's immensely helpful
[20:09] <edmoore> but I got one guy just ask a bunch of irrelevent questions under the guise of 'help' and then said 'you want to talk to a guy called jcoxon about your balloon stuff'
[20:11] <gordonjcp> hahaha
[20:11] <gordonjcp> edmoore: incidentally I just picked up a bunch of cheap digital remote thermometers, which work on 434.ish
[20:12] <edmoore> oh nice
[20:12] <edmoore> any idea what power tx?
[20:13] <gordonjcp> a handful of mW probably

[20:35] <edmoore> hi Xenion
[20:35] <Xenion> hi folks :-)
[20:35] <Xenion> hello edmoore
[20:36] <edmoore> all well?
[20:37] <Xenion> nearly, just busy right now .. it's always the same ... you start IM ( like IRC and ICQ ) .. baam you've got 10 people bothering you ^^
[20:37] <Xenion> and for you ?
[20:37] <Xenion> but i've finally got mit Xtend 900 from maxstream ! :-)
[20:37] <Xenion> it tooked me 3 hours and some begging to find a good reseller :D
[20:37] <edmoore> nice
[20:38] <edmoore> if only we could use such things!
[20:38] <Xenion> ?
[20:38] <Xenion> why couldn't you ?
[20:39] <edmoore> 10mW limit

[20:39] <EI5GTB> not on ham bands :)
[20:40] <edmoore> EI5GTB: you have news?
[20:41] <Xenion> hum
[20:41] <Xenion> edmoore, never heard of that ...
[20:45] <edmoore> indeed, it's just an annoyance of living here
[20:46] <EI5GTB> edmoore, theres no 10mw limit on the ham bands!
[20:46] <EI5GTB> for instance, i could run a wireless access point on 500w legally...
[20:46] <EI5GTB> well, 400w
[20:46] <edmoore> indeed, but you can't fly then on unmanned things in GB at least
[20:47] <edmoore> which is the point at hand
[20:47] <EI5GTB> yea
[20:47] <EI5GTB> but im hoping to change that
[20:48] <EI5GTB> i have a letter in my hand from comreg that says they will consider letting me do it if i get the all clear from the IAA
[20:48] <edmoore> cool
[20:48] <edmoore> i might change my nationality
[20:48] <Xenion> funny im having holidy in GB in 3 days ^^
[20:55] <edmoore> oh cool - where are you headed?
[20:55] <Xenion> just planning it right now with a friend of mine ( who lives in london right now )
[21:14] <robert1971> edmoore: how much for the badger board? £799.00

[21:14] <robert1971> Here
[21:14] <edmoore> oh blimey. Would have to work it all out
[21:15] <robert1971> =1 ICON 7000
[21:15] <edmoore> oh christ you make a good point
[21:15] <robert1971> I thought you were making that earlier
[21:15] <edmoore> truthfully if £799 landed in my lap, I have tuition fees to start chipping away at
[21:15] <robert1971> jiffe88: Not cloing myself
[21:16] <robert1971> Solve avr nastyness
[21:16] <robert1971> Solved
[21:16] <robert1971> 1K is only 1000 Chars
[21:16] <robert1971> Obv. I know
[21:16] <edmoore> what was the prob?
[21:16] <robert1971> My struct had ~900 bytes and a few buffers had 4*500 chars
[21:17] <robert1971> Rolling out of the data stack I think
[21:17] <edmoore> ah
[21:17] <robert1971> Reduced my bloat ware and now it's all happy
[21:17] <edmoore> well if you want a badger... :)
[21:17] <edmoore> have you had a look at the ngw100?
[21:17] <robert1971> ?
[21:18] <robert1971> WTFIT
[21:18] <robert1971> What the fuck is that
[21:18] <robert1971> :)
[21:18] <robert1971> Is there a link?
[21:19] <edmoore> http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4102
[21:19] <edmoore> about $80
[21:20] <edmoore> laurence used one in his aerosoll sampling mission which has yet to fly
[21:20] <robert1971> BTW I'm in avr bliss now. 24 hours slog an sucess
[21:20] <robert1971> and success
[21:20] <edmoore> both eh
[21:21] <robert1971> I have just seen ICARUS MK11
[21:21] <edmoore> :D
[21:21] <robert1971> Bugger building a board when they do it for you
[21:21] <edmoore> it's a grand wee thing
[21:21] <edmoore> and you've obv got linux on there
[21:21] <robert1971> Linux on board too
[21:21] <edmoore> all the documentation is a mediawiki help on the onboard flash
[21:21] <robert1971> Oh yes, and we all love linus
[21:21] <robert1971> Oh yes, and we all love linuslinux
[21:21] <robert1971> humm
[21:22] <robert1971> You know what I mean

[21:23] <robert1971> Any one want one?
[21:23] <edmoore> not right now
[21:23] <edmoore> might be good for the tracking tower though
[21:24] <robert1971> ?
[21:24] <edmoore> if the rtty decoding can be squeezed onto it
[21:24] <robert1971> 4th oct
[21:24] <edmoore> oh right. nah probs won't need it that soon :)
[21:24] <edmoore> though it would be fun to experiment with
[21:24] <robert1971> Tracking tower?
[21:25] <robert1971> Is that what your building for auto tracking?
[21:25] <edmoore> yeah
[21:25] <edmoore> track-a-tron
[21:25] <robert1971> Ahh all clear now
[21:25] <edmoore> sorry
[21:25] <robert1971> Awsume
[21:26] <robert1971> Right there is going to be a beacon launch on Thursday. Anyone with radios welcome to track. Launchw will be from WF12 0NQ uk
[21:26] <edmoore> will be in cam then
[21:26] <robert1971> There will be a secret CW message to see if you can decode
[21:26] <edmoore> :)
[21:26] <edmoore> CW eh...
[21:27] <robert1971> The cost is one avr mega 8 + TX and antena about 25 squid all in
[21:27] <robert1971> morse :(
[21:27] <robert1971> No rrty yet
[21:28] <robert1971> Thats for beacon KMII
[21:28] <robert1971> MK III
[21:28] <edmoore> it means can do it by ear
[21:28] <edmoore> so that's ok then
[21:28] <edmoore> :)
[21:28] <robert1971> Some thing to do with sex and that comes to mind

[21:35] <mc-> hi robert1971, I saw you're planning on launching a beacon
[21:36] <mc-> how about a cheap GPS module? I've got some that are only a few pounds each.
[21:38] <mc-> natrium42, don't bother with the Flex5000, it's overpriced, the softrocks have similar performance for a few $.
[21:38] <Xenion> mc-, uhh what device ?!
[21:38] <mc-> I got some cheap Atmel modules, but they need an antenna
[21:38] <Xenion> mc-, named ?!
[21:38] <mc-> about 40mins soldering
[21:39] <mc-> can't remember the name, ordered from Taiwan
[21:41] <Xenion> looks good
[21:41] <Xenion> thanks for the hint
[21:41] <Xenion> just what i was looking for :)
[21:41] <Xenion> entered "atmel gps oem" in google :D
[21:41] <Xenion> did the trick

[23:00] <Laurenceb_> hello
[23:01] <Laurenceb_> a whole day of sanding beams, such fun
[23:29] <RocketBoy> anyone know anything about wav file sample rates - I'm getting screwy results
[23:31] <edmoore> as it happens I did once generate some with octave a bit ago
[23:31] <gordonjcp> RocketBoy: a wee bit, what's up?
[23:34] <RocketBoy> well some bitrate set in linux sound funtions (sf_...) seem to generate accurate frequencies - and some don't
[23:34] <RocketBoy> 48000 24000 44100 are all fine
[23:34] <gordonjcp> RocketBoy: is your card resampling?
[23:34] <RocketBoy> but 22050 and 11025 dont
[23:36] <RocketBoy> I don't think so - I think the prob is in the wave file generation becuse windows properties report slighlt wrong sample rates for the files
[23:36] <RocketBoy> i.e. 48000 24000 44100 are all fine
[23:36] <RocketBoy> but 11025 is reported as 11250
[23:36] <RocketBoy> and 22050 as 22500
[23:37] <RocketBoy> but 44100 is reported as 44100
[23:38] <RocketBoy> 11025 22050 and 44100 (notice x 2 factor) are the original standard sound card sampling rates
[23:38] <RocketBoy> so those arte the ones I would have expected to be accurate
[23:39] <RocketBoy> frequencies played back form the 11025 and 22050 files are slightly off
[23:39] <RocketBoy> so I suspect windows really thinks these are 11250 and 22500 files
[23:40] <RocketBoy> I'm suspecting the linux sound function calls
[23:44] Ebola (n=Ebola@unaffiliated/ebola) left irc: ""Don't let worry kill you -- let the church help.""
[23:44] <RocketBoy> another stange thing is that for the 22050 file the sample rate is reported as 22500 with 16 bit samples - but the average data rate is reported as 44100kbps (i.e 2 x 22050)
[23:55] <RocketBoy> oh well at least it works ok on some rates
[23:55] <RocketBoy> night all
