[09:36] <gonzo_> but, does the new habitia/snus page have the radial lines to the RX sites?

[09:43] <craag> habmap - yes
[09:44] <gonzo_> Being aboue to hold the mouse over the track and get data for all posns was noce. But suppoose that was just too much data and causing the page to be slow?
[09:44] <craag> Yeah I think that was one of the major memory hogs of snus
[09:44] <jededu> Ping upu
[09:44] <fsphil> indeed. every upload got pushed to the client
[09:44] <fsphil> that it worked as well as it did for the B flights was amazing
[09:45] <gonzo_> the uk habbers should stop being so successful with their balloons, that would keep the data down!
[09:46] <daveake> yeah, whatever happened to u-burst-down? :p
[09:46] <daveake> up
[09:46] <jededu> Are there any trackers in that part of russia ? :)
[09:46] <craag> boring
[09:46] <qyx_> speaking of habbing, i was playing with OV2640 cheap camera module over the weekend
[09:46] <craag> too predictable
[09:46] <fsphil> you have my attention
[09:46] <qyx_> it can be interfaced to cheap stm32 (without camera interface) quite easily
[09:47] <fsphil> I've an OV2640 on order
[09:47] <gonzo_> the good old days. Non of this long haired, new fangled floating in our day.....
[09:47] <fsphil> probably won't get it before 2015
[09:47] Action: craag also has 3 on order for work stuff
[09:48] <qyx_> http://qyx.krtko.org/embedded/ov2640_stm32/
[09:48] <qyx_> but this is llama-like interface
[09:48] <craag> What tier of stm32 did you use?
[09:48] <qyx_> i used F4 discovery but avoided DCMI
[09:48] <qyx_> just because i had it there
[09:48] <qyx_> *here
[09:48] <fsphil> you just need to watch for the sync and then start dma'ing the data?
[09:48] <qyx_> yep
[09:48] <qyx_> href, sync and dma from gpio
[09:49] <jededu> got to go bbl
[09:49] <fsphil> does it send a fully formed jpeg or just the DCT data?
[09:49] <Upu> ho jededu
[09:49] <qyx_> fsphil: full including header and trailer
[09:50] <fsphil> ah handy
[09:50] <fsphil> what's the image quality like?
[09:50] <qyx_> http://i.imgur.com/agCewrl.jpg
[09:50] <qyx_> the rest didn't fit in the 60KB buffer
[09:50] <fsphil> that'll do
[09:50] <fsphil> haha
[09:51] <qyx_> hm, it is 49KB
[09:51] <fsphil> much better than the expensive 640x480 jpeg cameras
[09:51] <craag> recompressed imgur magic?
[09:51] <qyx_> ah, that may be the case
[09:51] <qyx_> no, it isnt
[09:52] <qyx_> i need to investigate it further
[09:52] <qyx_> it has 40KB actually
[09:52] <fsphil> you got it for a few USD, I think mine was $17
[09:52] <qyx_> also i need to adjust the shutter, now it is ~2sec
[09:52] <qyx_> $7
[09:53] <qyx_> http://www.ebay.com/itm/281067291314
[09:53] <qyx_> $9.99 now
[09:53] <qyx_> $7 is without the breakout board
[09:53] <fsphil> ah, doesn't post to the UK
[09:54] <fsphil> aww
[09:54] <fsphil> ah well already ordered it
[09:54] <qyx_> Excludes: Germany, United Kingdom
[09:54] <Upu> thats a wierd exclusion
[09:54] <qyx_> interesting
[09:54] <Upu> wonder why
[09:54] <craag> I ordered from this place: http://www.uctronics.com/results.html?search_in_description=1&keywords=ov2640&categories_id=
[09:54] <qyx_> 100pcs for $400, cheap
[09:56] <craag> Also there's the ~$1.50 ones around if you can do jpeg on the stm32 - no idea how easy that is though - sounds like it'd need a lot of ram
[09:57] <qyx_> you would either need to do it realtime or store the whole frame in SRAM
[09:57] <fsphil> there was some talk of that before
[09:59] <craag> to do it realtime you need your output sink to be fast enough to dump it all within a single frame-period if I understand correctly
[09:59] <fsphil> memory is still tricky though
[09:59] <qyx_> ou would need to store8 lines afaik
[09:59] <fsphil> for 640x480, you'd need 640x16 pixels before you can begin encoding
[09:59] <qyx_> 16?
[09:59] <qyx_> thats about 20KB
[10:00] <fsphil> for chroma subsampling yea
[10:00] <fsphil> though you can do without that for x8
[10:00] <fsphil> produces a slightly larger jpeg
[10:01] <qyx_> so 2x20K for two buffers, might be doable on F401, it costs ~4¬
[10:01] <fsphil> you'd still need room for the jpeg
[10:02] <qyx_> pfff
[10:06] <fsphil> there's the 2x1 subsampling which would only require x8 lines
[10:06] <jededu> ping upu
[10:06] <fsphil> it halfs the horizontal chroma data, keeps the vertical resolution
[10:06] <Upu> hi jededu
[10:07] <jededu> Did you get the order
[10:07] <Upu> yep
[10:07] <fsphil> would be a nice compromise
[10:07] <jededu> Cool
[10:07] <Upu> I'm at home atm but should ship today
[10:07] <jededu> Np
[10:07] <qyx_> maybe, still you would need at least 64K for 640x480
[10:08] <jededu> Latvia that was a suprise :)

[10:28] <diegoesep> fsphil, qyx_ I was thinking also to interface OV2640 with STM32F4
[10:29] <diegoesep> and one of the issue is the ram size
[10:29] <qyx_> on F4 it is not, you can easily fit 1280x1024 jpeg in ram
[10:29] <diegoesep> there are several ways to handle this: use a STM32 with SDRAM interface and add SDRAM chip for DMAing jpeg
[10:30] <qyx_> my 1024x768 jpeg has about 40K
[10:30] <diegoesep> or use a FIFO chip between the OV2640 and DCMI
[10:30] <diegoesep> like they have done on the arducam module
[10:30] <qyx_> i am targetting low cost, so these are not options
[10:31] <diegoesep> I see
[10:31] <qyx_> even sdram adds few ¬ to the BOM
[10:31] <diegoesep> I'm targetting low power consumption and weight, but I would like to store and send higher quality pictures
[10:31] <qyx_> i would rather use 2¬ mcu with 320x240 jpeg than 10¬ mcu + sdram

[10:31] <fsphil> for my use (ssdv) the typical image size is going to be around 512x384, will fit in the F4 fine
[10:32] <diegoesep> because with a 40kb jpeg image you may not have good quality image
[10:32] <qyx_> yep, it owuld fit also F401 with 64K ram
[10:32] <qyx_> which costs one third of F407
[10:32] <diegoesep> the STM32F411 has 128kb of SRAM
[10:33] <qyx_> but shill not available :/
[10:33] <qyx_> on farnell
[10:33] <diegoesep> with ssdv , what is the average size of the image ?
[10:34] <fsphil> it varies
[10:35] <fsphil> good question though, I could probably query that

[10:41] <diegoesep> ouch
[10:42] <craag> lots of black, and often bright white :)
[10:42] <diegoesep> you are using 9600bps RTTY?
[10:42] <craag> usually 300/600 baud
[10:45] <edmoore> 9600 rtty would be a bit bandwidthy for your average ham audio channel
[10:46] <fsphil> the average image size is 412x285

[10:53] <daveake> Some have tried SSDV at >9600 albeit not RTTY :)
[10:53] <diegoesep> so you usually transmits 6-40kb images with ssdv?
[10:53] malclocke (~malc@60-234-172-149.bitstream.orcon.net.nz) left irc: Quit: Ex-Chat
[10:53] <diegoesep> what is the biggest SSDV image that was transmitted?
[10:54] <daveake> 1920 x 1080
[10:54] <daveake> but that was using a fast lora mode
[10:54] <diegoesep> daveake I'm currently trying to use LORA module too
[10:54] <daveake> I generally go for about 800x500 pixels when using rtty
[10:54] <diegoesep> what LORA parameters where you using? spread factor = 6?
[10:55] <daveake> Yeah everything "up to the max"
[10:55] <diegoesep> I see
[10:55] <diegoesep> and 20.8khz bandwith?
[10:55] <daveake> However next time I'll slow it down a bit
[10:55] <daveake> No that was 256k on 868
[10:55] <daveake> Fastest you can get on 20.8kHz bandwidth is about 1400 baud
[10:55] <daveake> But that does work very well
[10:55] <diegoesep> ok , because I was finding a way to have higher bitrate than 1400bauds with 434mhz band
[10:56] <daveake> Yeah not allowed, not at 100% DC anyway
[10:56] <diegoesep> and in France were only allowed to use 144.650Mhz for HAB
[10:56] <diegoesep> but not limited by the power

[10:57] <daveake> 434 ISM is allowed surely?
[10:57] <diegoesep> it is not clear yet ,
[10:57] <daveake> hmmm
[10:58] <diegoesep> and I'm always thinking about the balloons crossing from UK to france
[10:58] <daveake> indeed
[10:58] <diegoesep> i'm sticked to the 144.650 freq
[10:58] <diegoesep> but it will be much easier to work with 434 mhz antennas and stuff :)
[10:58] <mattbrejza> is that ISM? :/
[10:59] <diegoesep> daveake, for the 256k on 868, was it with a balloon test?
[10:59] <daveake> yes
[11:00] SushiKenBrown (~quassel@cmr-208-124-174-194.cr.net.cable.rogers.com) left irc: Ping timeout: 272 seconds
[11:00] <daveake> However it suffered from no FEC/CRC so I need to sort that and try again
[11:00] <diegoesep> what what the transmitting power and range did you got?
[11:00] <daveake> It's a 5mW limit cough
[11:01] <daveake> I need to try again
[11:01] <diegoesep> what was the range with 5mw?
[11:01] <daveake> I wouldn't know :/
[11:01] <diegoesep> did you got better results compared to RTTY using same bandwith and power?
[11:02] <daveake> It did work for a while before I needed to add the habamp
[11:02] <daveake> I did another flight comparing lora and rtty on 434
[11:02] <qyx_> you can use 433 for fast downlink even at 100% duty
[11:02] <qyx_> at 0dBm :P
[11:03] <daveake> And lora did very well - I was having to aim the yagi on rtty, whereas a lora receiver with a 1/4 wave, horizontal on a bench, worked fine
[11:03] <diegoesep> good daveake :)
[11:03] <daveake> qyx_ yeah didn't bother with that :)
[11:03] <diegoesep> I plan to use LORA in all my next HAB launches :)
[11:03] <daveake> It'll be good to have some others try it
[11:03] <diegoesep> I will launch it from south of france
[11:04] <diegoesep> it may be too far , even at 35km altitude? :p
[11:04] <qyx_> i tried with 100kbit/s with golay fec
[11:04] <qyx_> although not on a hab
[11:04] <mattbrejza> i would transmit lora and rtty to be safe though
[11:04] <qyx_> about 3km are possible with 0dBm
[11:04] <daveake> yeah, with lora you're going to be on your own
[11:05] <mattbrejza> i got my BT module working with my android app last night
[11:05] <mattbrejza> not actually too bad
[11:05] <mattbrejza> to get working
[11:05] <diegoesep> in the specs you can use 17dbm for 100% duty cycle
[11:05] <diegoesep> and 20dbm with 1% duty cycle
[11:05] <daveake> I did one with 2 balloons, one sending on rtty what it received from the other via lora. That worked really well
[11:06] <diegoesep> nice
[11:07] <daveake> Next time I'll try uploads from the ground too
[11:07] <pc1pcl-qrl> French HAM working on a 70cm transmitter for balloons, so seem plausible it is allowed to be used: http://ballons-radioamateurs.blogspot.nl/2014/06/emetteur-ballon-radioamateur-434400-mhz.html
[11:08] <daveake> I thought that 434 ism was an EU-allowd thing, though I assume FR can override
[11:08] <diegoesep> I have checked with Alain F6AGV and it seems that currently only the 144.650 is officially allowed
[11:08] <diegoesep> so I plan to use lora modules with different filters for 2m band
[11:09] <qyx_> french is very weird also at classic wifi
[11:10] <diegoesep> and for the 868mhz 256k test daveake , what power is allowed in the UK?
[11:10] <pc1pcl-qrl> I suppose it depends if you want to use it as amateur, or as 'unlicensed, low-power'. to have any /AM amateur use even if only one freq. in 2m spectrum, I guess is already better than what is available in the UK..
[11:11] <diegoesep> I have a radioamateur license
[11:13] <craag> ah so you've got lora modules working down at 144? Are you using the hoperf modules or the raw ICs?
[11:13] <fsphil> loraprs
[11:14] <craag> Not such a bad idea
[11:14] <fsphil> would it not be considered a secret code
[11:14] <daveake> diegoesep That depends - the 868 band is divided up and there are various power/bandwidth/DC options
[11:14] <craag> Although penalty for using ax25 on it is death
[11:14] <Upu> lol
[11:14] <fsphil> lol yes
[11:14] <diegoesep> there are lora board working at 144mhz for mbed evaluation
[11:15] <diegoesep> no sorry these ones are for 434
[11:16] <craag> fsphil: I don't think people care as long as you 'can' decode it easily with the right kit (eg. d-star voice codec)
[11:16] <diegoesep> but I'm currently in discussion with dorji for making 144mhz modules too
[11:16] <diegoesep> I will start the test with dorji 434 then switch with dorji 144 when it will be available
[11:17] <craag> by that logic using rc4/des is borderline encryption/data whitening ;)
[11:17] <diegoesep> lora chip are publicly available so I don't thnik it is an issue
[11:19] <fsphil> goes against it being a hobby thing though
[11:19] <diegoesep> I see
[11:20] <craag> Yeah I've always been dubious of ambe's place in a hobby
[11:20] <craag> but I'm sure mattbrejza will take beer donations towards reverse-engineering lora ;)
[11:20] <diegoesep> lol
[11:22] <craag> Darksid_e dug out their patents the other day and so I think has a *rough* idea of whats going on
[11:22] <fsphil> does it document the bitstream format?
[11:23] <craag> haven't looked myself - but all they'd need is some magic coefficient to make finding the full decode solution very difficult
[11:26] <fsphil> since it appears to be an fsk mode, we could make our own version with the ntx2
[11:27] <diegoesep> for lora you mean fsphil ?
[11:28] <craag> what would be the purpose of doing that?
[11:28] <diegoesep> if we can make a OPEN LORA modulation it would be nice for the community
[11:28] <qyx_> i am planning to look into DSSS using rfm69 or compatible transceiver
[11:29] <qyx_> should be doable
[11:29] <diegoesep> spread sprectrum modulation?
[11:29] <fsphil> lora isn't really spread spectrum
[11:29] <craag> matt's protocol into an mfsk modulator would work rather well I think
[11:29] <craag> I forget the name - but what he tried with afsk
[11:30] <fsphil> turbohab?
[11:30] <craag> that's the one
[11:30] <fsphil> does the lora modulation offer any advantage over mfsk?
[11:30] <craag> then 'habpack' for binary telem packing
[11:30] <fsphil> might be easier to correct for drift
[11:31] <craag> yeah seems to use some form of modulated sweeping that I imagine is quite drift-immune

[14:39] <edmoore> Michemto, the rtl-sdr sticks (google) are common on ebay but you'll probably want a habamp or similar to increase their sensitivity for tracking typical balloons
[14:40] <gonzo_> or the funcube dongle pro+
[14:40] <gonzo_> though they are probably not on ebay

[14:41] <edmoore> HF_ATL_, ah yes i remember
[14:42] <edmoore> there is probably not a great advantage to both
[14:42] <HF_ATL_> hope to get here more often
[14:42] <edmoore> if you can use APRS legally there's likely a lot more pre-existing infrastructure to support that
[14:42] <edmoore> over europe
[14:42] <HF_ATL_> probably the rtty can be disabled if i go to aprs route?
[14:42] <edmoore> yep
[14:43] <HF_ATL_> i'm erally considering the options for tracking before getting the balloon
[14:43] <day> UpuWork: are you a transmitter dealer? :p
[14:43] <edmoore> he is
[14:43] <HF_ATL_> and i believe the code is provided is consolidated ready to use, right?
[14:44] <UpuWork> I sell transmitters yes :)
[14:44] <edmoore> i don't know, i've always just built my own electronics
[14:44] <UpuWork> HF_ATL_ if you're on about the HAbduino you could disable RTTY yes
[14:44] <UpuWork> just comment out the line where it turns on the 70cms transmitter
[14:44] <day> UpuWork: how did that happen? Do you work for a transmitter building company?
[14:44] <edmoore> he just resells them day
[14:44] <UpuWork> nope I just get them from Radiometrix and HofeRF
[14:44] <UpuWork> HopeRF
[14:45] <day> i see
[14:45] <HF_ATL_> UpuWork, thank you. And it will be straightforward getting more sensor for arduino and joining them in the code to transmit those additional parameters as well?
[14:45] <UpuWork> I have an agreement with Radiometrix to provide support to amateur's so they don't have too
[14:45] <day> But doesnt radiometrix ship to private persons as well?
[14:45] <UpuWork> they do yes
[14:45] <UpuWork> but I'm cheaper
[14:45] <day> o0
[14:45] <UpuWork> HF_ATL_ possibly, possibly not
[14:45] <day> how
[14:46] <UpuWork> depends if you start sticking libraries on there that do random stuff to interupts
[14:46] <UpuWork> because I have agreement with Radiometrix :)
[14:46] <edmoore> day, have you ever tried to buy 1 of something from a distributor?
[14:46] <day> didnt read that one :}
[14:46] <UpuWork> also my NTX2B's are frequency agile
[14:46] <UpuWork> Radiometrix's aren't
[14:46] <edmoore> and they get angry about trade accounts and the paperwork, and ask why you can;t just buy 500?
[14:46] <day> edmoore: thats what we do :D
[14:46] <HF_ATL_> well I have some experience programming but not on arduino, just basic c and matlab
[14:47] <day> nah actually we tell private persons to fuck off
[14:47] <UpuWork> invaribly if you start using libraries something will break
[14:47] <UpuWork> exactly day, I don't
[14:47] <UpuWork> so come to me
[14:47] <edmoore> so upu can buy 500 and sell them to us at a better price than us all buying 1 each from radiometrix direct
[14:47] <HF_ATL_> is there a future possibility of having the code developed by you to gather sensors data?
[14:47] <edmoore> ce n'est pas trop compliqué
[14:47] <UpuWork> Depends I only ever intended it to be a platform for others to base off
[14:47] <UpuWork> you see what you want won't be what others want

[14:58] <HF_ATL_> also my intention is to support here the community so much prefer to buy from uk
[14:58] <edmoore> the kit version of a habduino is
[14:58] <edmoore> an arduino
[14:58] <edmoore> an arduino prototype shield
[14:58] <edmoore> a radiometrix
[14:58] <edmoore> and ublox
[14:58] <edmoore> voila
[14:59] <UpuWork> basically yes
[14:59] <UpuWork> +Adafruit step up
[14:59] <day> why are people so much into arduinos?
[14:59] <UpuWork> Are you wanting a habduino with no MTX2 on it ?
[14:59] <edmoore> day, they won a few years back
[14:59] <edmoore> we shouted at the tide
[15:00] <HF_ATL_> it would be awesome if there is no need to buy additional the arduino uno, but instead come already integrated
[15:00] <edmoore> it still came up the beach
[15:00] <edmoore> what can you do?
[15:00] <edmoore> just go for a swim
[15:00] <UpuWork> that ups the BoM alot HF_ATL_
[15:00] <UpuWork> well
[15:00] <UpuWork> a little
[15:00] <HF_ATL_> yes, with 300mw 144.8 on it
[15:00] <UpuWork> you could make one
[15:01] <day> edmoore: idk. i just prefer the knee deep ocean. and not the knee deep yellow swimming pool :/
[15:01] <HF_ATL_> better range, better tracking stations around here for that freq
[15:01] <navrac_2E0VKK> and a gpsdo, hf tx etc etc etc
[15:01] <HF_ATL_> just need to build a dipole and a 5 element yagi for trackign and I'm done
[15:02] <UpuWork> afk
[15:02] <HF_ATL_> bom? bill of materials?

[15:46] <adamgreig> just connect each pin twice
[15:46] <edmoore> identify the two pins responsible for VCC and gnd
[15:46] <adamgreig> it should work out fine
[15:46] <edmoore> these are your power pins
[15:46] <edmoore> there are then two further pins - for the serial port
[15:46] <edmoore> Tx and Rx
[15:46] <edmoore> identify those
[15:47] <edmoore> with those 4 pins (which is less than half of nine and fully less and one quarter of 18) you should be in business

[15:48] <pc1pcl> http://learn.adafruit.com/downloads/pdf/adafruit-ultimate-gps.pdf seems the 9 pins are labeled quite clearly..
[15:48] <gpearson> Okay will give it a shot
[15:51] <qyx_> diegoesep: no, stm32 dma cannot do peripheral-peripheral dma
[15:51] <qyx_> although it may be possible to run 2 dma simultaneously sharing single circular buffer
[15:52] <Myself> that sounds like a glorious race condition in the making
[15:52] <edmoore> or a clever algorithm for finding cyclicity in linked lists
[16:01] <diegoesep> ok gyx_ thanks :)
[16:02] <diegoesep> so we can only do dma from gpio to SRAM
[16:03] <diegoesep> and if using DCMI , do we have possibility to DCMI to SDIO 8 bits mode?
[16:04] <HF_ATL_> has anyone already used the habduino and collecting data automatically into a sd card?
[16:09] <edmoore> please stop saying habduino
[16:09] <Maxell> "the habduino" ?
[16:10] <edmoore> people have used sd cards with arduinos
[16:10] <edmoore> of course
[16:10] <edmoore> google is your friend here
[16:10] <edmoore> there is nothing habduino-specific about any of your questions
[16:10] <HF_ATL_> why not? is not named habduino?
[16:11] daveake (daveake@daveake.plus.com) left #highaltitude ("Leaving").
[16:11] <Myself> that's like saying, "how do I take a 1995 ford focus to mcdonalds?" when you should be asking "what is the address of mcdonalds?"
[16:11] <edmoore> exactly
[16:11] <edmoore> none of your questions are habduino-specific
[16:12] daveake (~daveake@daveake.plus.com) joined #highaltitude.
[16:12] <edmoore> the habduino is a shield for a gps and a radio to connect to an arduino
[16:12] paul_HAB-P (~paul_HABn@host165-120-30-98.range165-120.btcentralplus.com) left irc: Ping timeout: 244 seconds
[16:12] <edmoore> these are just arduino questions, and even then that's a bit specific, but at least by using the term arduino in google you're likely to find beginner-friendly stuff
[16:13] <HF_ATL_> well I understand but of course as a shield there will be some I/Os that can not be available, just to want to know the expected "limitations"
[16:15] <edmoore> so research sd cards and arduinos, see that you might need to use something called an SPI port, and then see what the habduino shield uses
[16:15] <HF_ATL_> because as I saw, the sd card is not embedded in the shield
[16:16] <HF_ATL_> all right thank you

[17:22] <Upu> just had a huge number of clients connect to - - [15/Dec/2014:17:17:21 +0000] "POST /xmlrpc.php HTTP/1.1" 500 251 "-" "-"
[17:22] <Upu> across multiple sites on the box
[17:22] <Upu> its back up now
[17:22] <Adam012> Hi Upu, sorry to hear that. I was just in the middle of working out an order before it went on the fritz.
[17:22] <Upu> yeah sorry
[17:22] <Upu> we have a new machine going in this week
[17:22] <Adam012> That's okay, its not like its your fault!
[17:23] <Upu> load average: 18.73, 52.69, 41.90
[17:23] <Upu> was 140 :<
[17:23] <Adam012> More speed, storage ot both?
[17:23] <Upu> more rate limiting on individual accounts
[17:23] <lz1dev> Upu: sounds like someone is bruteforcing user/pass :)
[17:24] <Upu> yeah business as usual
[17:24] <Upu> another day another pile of spammers whacking the server
[17:24] <lz1dev> if you not using xmlrpc is probably best to deny access to it
[17:25] <Adam012> Its a shame that its such a pain to trace, what fun could be had if they'd forgotten to change the password on their own router.
[17:25] <Upu> trouble is we don't control the sites on there
[17:25] <Upu> so customers upload what they want
[17:25] <Upu> including it seems Joomla and about 98,734 vuleribilities per site
[17:26] <Ian_> Lol
[17:26] <lz1dev> i believe the offical metric for those is vuln per minute
[17:26] <Adam012> No love for wordpress?
[17:26] <Upu> I like wordpress
[17:26] <Upu> that only comes with about 20,000 vulns per site
[17:26] <Adam012> ;-)
[17:26] <Upu> its a huge improvement
[17:26] <lz1dev> well
[17:27] <lz1dev> there are plugins to increase that number
[17:27] <Upu> though in seriousness Joomla should die in a fire
[17:28] <Adam012> But it's "The CMS Trusted By Millions for their Websites"
[17:29] <Adam012> Ikea, Ebay, Barnes and Noble, UNRIC, etc make them look like they know what they are doing.

[21:21] <paul_HAB-P1> I can see lots of info on serving sdr on RTL hardware. Has anybody done this with a funcube dongle?
[21:21] <Upu> how do you mean ?
[21:22] <paul_HAB-P1> I'd like to have a machine which had the funcube dongle connected and broadcasts for other machines to use - like websdr...

[21:22] <Upu> and lol that you replaced noob with P1 :)
[21:22] <paul_HAB-P1> :)
[21:22] <Upu> yeah you can do that
[21:23] <Upu> http://v2.sdr-radio.com/
[21:23] <Upu> but its one client at once
[21:24] <paul_HAB-P1> ah - windows. Looking for a linux equivalent so I can run it on a headless board (an Odroid U3)
[21:25] <Upu> rtl-tcp
[21:25] <Upu> may not work with FCD
[21:26] <paul_HAB-P1> thats the thing - doesn't rtl need the rtl chipset to work?
[21:26] <Upu> http://sdr.osmocom.org/trac/wiki/GrOsmoSDR
[21:26] <Upu> well they are talking about FCD's here
[21:26] <Upu> so not sure
[21:26] <Upu> try it ?
[21:26] <paul_HAB-P1> Hand on - I can see somebody mentioning it: http://sdr.osmocom.org/trac/wiki/rtl-sdr
[21:27] <paul_HAB-P1> nice - i'll give it a shot once the cube turns up :)
[21:27] <Upu> good radio that
[21:27] <paul_HAB-P1> ^funcube
[21:27] <paul_HAB-P1> Cool - I'm sure its completely wasted on a noob like me...
[21:27] <Upu> Its not
[21:27] <Upu> I had three at one point

[21:33] <paul_HAB-P1> Ah right I see, but how would you tune it?
[21:34] <mikestir> maybe hamlib?
[21:34] <mikestir> just tossing ideas about - I've done this with real radios but not an fcd
[21:34] <db_g6gzh> for cli control maybe use https://github.com/csete/fcdctl
[21:35] PE4FD (520ffa23@gateway/web/freenode/ip.82.15.250.35) joined #highaltitude.
[21:36] <mikestir> seems hamib's rigctld does support fcd, and that would have the advantage of being integrated with things like fldigi
[21:38] <db_g6gzh> and https://github.com/csete/fcdec has fcd_sequencer.sh which shows how to use sox to record IQ to a file, you could probably pipe through nc to go over the network
[21:39] <paul_HAB-P1> thanks for the pointers ill start playing with them :)
