[09:24] <Laurenceb__> hmm why did Leo launch 2 balloons...
[09:24] <Laurenceb__> worried about some record or something... :-D
[09:24] <pd3t> To make it a challange for the trackers to decode both ;)
[09:25] <mikestir> I have something with a much narrower shift than advertised on 434.350
[09:25] <bertrik> oh, I should be tracking right now
[09:25] <mikestir> wandering about
[09:25] <mikestir> looks like rtty with an idle gap every few seconds
[09:25] <Maxell> Herman-PB0AHX: dial for B-64?
[09:25] <pd3t> 501
[09:25] <Herman-PB0AHX> 499.8 bij me Maxell
[09:25] <Steve_G0TDJ> Maxell: I have 434.500.36 for 1500 center
[09:26] <Maxell> 434.500 and dl-lfidig audio on?
[09:26] <Maxell> ok
[09:26] <Herman-PB0AHX> dldigi audio on 1300
[09:27] <Laurenceb__> this turbohab thing sounds cool
[09:27] <Adam012> Our scale is not accurate. The weight was out by 200g!

[09:27] <mikestir> Adam012: your shift appears to be 330 rather than the advertised 690?
[09:28] <Maxell> ok Herman-PB0AHX
[09:28] <Maxell> nothing here yet
[09:28] <Adam012> I had to swap a resistor last night due to the shift being >1000
[09:28] <mikestir> ahh ok
[09:29] <mikestir> green there anyway - not bad copy
[09:29] <Adam012> I was rushed and on reflection 47k ohm may have been overkill
[09:29] <Maxell> Herman-PB0AHX: oops those carrires where mine
[09:29] <mikestir> 330 is a reasonably shift for 50 baud anyway
[09:29] <mikestir> reasonable*
[09:30] <mikestir> the long idle between bursts does upset the AFC though

[09:44] <mfa298> OZ1LRG: It may be due to the number of data points in the flights - try the links Maxell just posted as it seems to work better with lots of data.

[09:52] <G4MYS_Andy> yes Toomo
[09:53] <Geoff-G8DHE> 64/1000
[09:53] <G4MYS_Andy> no 64/1000 is correct answer!!!
[09:53] <mfa298> annoying that they are transmitting at the same time as otherwise rsis would mean one radio and one dl-fldigi could do both B- flights
[09:53] <fsphil> hehe
[09:53] <fsphil> yes
[09:53] <Geoff-G8DHE> But if you switch RSID on it will AFC and select the correct mode
[09:53] <Toomo> Im using a new setup and cannot decode
[09:53] <G4MYS_Andy> whatare you missing toomo?
[09:54] <Geoff-G8DHE> Show us a complete screen shot
[09:54] <G4MYS_Andy> is rx on usb and mode on screen on RTTYR?
[09:54] <mfa298> Geoff-G8DHE: except where B-64 seems to be starting halfway through B-65's transmission it would probably end up switching when you don't want them to - It looks like you can just get them both in the same audio pass band (although B-65 is just a bit too weak for me at the moment)
[09:55] <G4MYS_Andy> yes mine is in the same audio passband !
[09:55] <Toomo> Cheers 64 / 1000 it is thanks
[09:55] <G4MYS_Andy> using the one FT847, !
[09:55] <Geoff-G8DHE> Yes true if you've only one radio but DL-fldigi will at least adjust its centre for you

[10:02] <pd3t> Herman-PB0AHX: decoding B64 and B65
[10:03] <LeoBodnar> i think you can disable RSID searching the whole 3kHz+ spectrum
[10:03] <LeoBodnar> then it will only search within current modem passband (red lines)
[10:05] <G4MYS_Andy> So Ive learnt a bit more today with many thnaks lads!... and due to B64 I now know where London is on the map!!
[10:05] <LeoBodnar> Configure - >IDs deselect "Detector searches the whole passband"
[10:06] <LeoBodnar> yep, it worked for me, second dl-fldigi copy ignores RSID outside contestia b/w/
[10:06] <pd3t> yep i run two of them here to decode both
[10:07] <Steve_G0TDJ> UAD up
[10:08] <Geoff-G8DHE> That option should be a single use, then set it to start wide,once aligned, it only searches within

[11:00] <myier> it's the control application for the FCDP+ for linux-based systems

[11:00] VK2FAK (~John@121.91.36.139) joined #highaltitude.
[11:00] <Geoff-G8DHE> Ah don't know that one!
[11:01] <mfa298> myier: you may need to make sure you have the right version for your dongle (I think the software for the original FCD is different to the FCD Pro +)
[11:01] <daveake> superman going round a roundabout lol
[11:01] VK2FAK (~John@121.91.36.139) left irc: Read error: Connection reset by peer
[11:01] <mfa298> but apart from that I don't know. I thought SDR software had the frequency control built in
[11:02] <myier> mfa298: I thought I had, I have latest version of both
[11:02] <myier> mfa298: fldigi doesn't if I understand right?
[11:02] <myier> and I didn't find a way to connect gqrx to fldigi
[11:03] <mfa298> you can't feed the data from the FCD directly into dl-fldigi. you'll need something in the middle to convert the raw IQ data into audio

[11:04] VK2FAK (~John@121.91.36.139) joined #highaltitude.
[11:04] <myier> mfa298: I don't know why it works, but fldigi (not dl-fldigi, that may be the reason (dl-fldigi doesn't compile on my system)) lists the FCDP+ in the list of audio sources
[11:04] <mfa298> you'll need to get the audio from something like gqrx into dl-fldigi. The easiest and safest route is probably a cable from line out to line in (pulse audio on linux has caused a lot of people issues with bad decodes)
[11:04] chrisstubbs (~chrisstub@host86-171-138-41.range86-171.btcentralplus.com) joined #highaltitude.
[11:04] <myier> and it works well since I decoded my hab with that
[11:05] <myier> I think it's quite a shame to use an DAC + ACD to transport data from a process to another!
[11:05] <mfa298> interesting. I didn't think fldigi had support for the raw IQ data (which is what you get directly from the FCD)
[11:06] <mfa298> the FCD appears as a 192KHz audio device but that's just the raw IQ samples not demodulated audio
[11:06] <myier> let me see if I can find something that explain that
[11:06] <mikestir> fldigi probably demodulates one or the other of the I and Q channels, which is basically double sideband
[11:07] kuldeepdhaka (~kuldeepdh@unaffiliated/kuldeepdhaka) joined #highaltitude.
[11:07] <mikestir> so it will work if you tune below, but it will be 6dB down on snr
[11:07] <mfa298> On windows people use things like virtual audio cable. In theory you can so the same thing with pulse audio but it's caused a lot of people a lot of issues as it does some odd things with sampling rates which breaks decoding (I think the latest pulse audio may have fixed it but that may not be in distributions yet)
[11:08] <mikestir> what's superman up to with the funny noises?
[11:08] <myier> ok so that's not good to do what I do with fldigi
[11:08] <Geoff-G8DHE> looked like a reset
[11:08] <mikestir> myier: it should be fine with a good signal, but it's not going to work well when the signal gets weak or if you have qrm
[11:09] <myier> because indeed the FCDP+ is listes as a PortAudio device, regular sound device

[11:10] G6UIM (5b544f65@gateway/web/freenode/ip.91.84.79.101) joined #highaltitude.
[11:10] <myier> what about UDP transport, I've seen that gqrx and gnuradio in general can stream the IQ data to the network, isn't it possible to grab that with (dl-)fldigi?
[11:10] <mikestir> fldigi doesn't do any kind of demod - it can't handle IQ samples except in the suboptimal way you've already tried
[11:11] <myier> yes right sorry, so what about streaming the sound data?
[11:11] <mfa298> I think some people have modified dl-fldigi to take audio input via a fifo
[11:11] <myier> or using a unix pipe or something
[11:11] <myier> yeah that'd be great
[11:11] <mfa298> but I'm not sure if that code is available anywhere or how well it worked
[11:12] <myier> I'll look it up
[11:12] <mikestir> you can do it with pulseaudio but there's a bug in the version in a lot of distros that messes up the sample rate
[11:12] <Herman-PB0AHX> yesssssss first green from super
[11:12] kuldeepdhaka (~kuldeepdh@unaffiliated/kuldeepdhaka) joined #highaltitude.
[11:12] <mikestir> if you use a very new distro it might be ok
[11:12] <myier> ok I'll try it too
[11:13] <mfa298> as I mentioned before the easiest and safest method is probably an audio cable between line out and line in. Tried tested and you can get it working in minutes!
[11:13] VK2FAK (~John@121.91.36.139) joined #highaltitude.
[11:13] <mfa298> (where most of that time is rummaging in a box for a suitable cable)
[11:13] <myier> On my laptop I just have a microphone input, which is quite bad
[11:14] <mikestir> that pulsing on the superman signal sounds like the linux "heartbeat" led trigger
[11:15] <seventeen> You need to add "default-sample-rate = 48000" to /etc/pulse/daemon.conf to correct the samplerate... works for me.

[15:07] <mfa298> they should appear you may just need to wait a bit (or possibly reload)
[15:07] <mfa298> although the predictions for B-64 won't be that useful ( the predictions assume an up, burst, down flight not a floating flight)

[15:39] <mikestir> esculca: you shouldn't really be testing in online mode while there are live flights up, but do you have green decodes in fldigi?
[15:39] <esculca> mike, you're right
[15:39] <esculca> do you want me to turn it off?
[15:39] <esculca> green decodes?
[15:39] <esculca> what does that mean?
[15:40] <mikestir> first thing to check is that fldigi can decode your telemetry. if it can then you should see it come up in green at the top at the end of each complete message
[15:40] <esculca> that's what is wrong then
[15:40] <mikestir> you can test that in offline mode - it will still come up green or red
[15:41] <chrisstubbs> craag_Phil_M0DNY, was the turbo payload working on the ground? I dont think anybody got anything from it at all

[15:46] <mikestir> yes, that should be fine but suggest sending 4 or 5 $. This won't prevent it from decoding however
[15:46] <Geoff-G8DHE> do you need the last , before the * ?
[15:46] <mikestir> no
[15:46] <myier> what is the purpose of the dollar signs?
[15:46] <mikestir> to signify the start of the sentence
[15:47] <myier> of multiple dollar signs I should have said
[15:47] <mikestir> sometimes the AFC can drift out a bit between sentences, especially if there's a gap
[15:47] <mikestir> this can mean you lose the first character or two
[15:47] <myier> ok
[15:47] <mikestir> if you only sent two $ and you lost one the sentence wouldn't decode even if it was otherwise perfect
[15:47] <chrisstubbs> myier, are you using a checksum?
[15:48] <myier> yes
[15:48] <esculca> used 4 $$ but it still doesn't work

[15:52] <mfa298> screenshot of the same thing would probably help
[15:52] <esculca> i am trying to get rid of them

[15:53] <esculca> I am calculationg the CRC with the $$
[15:54] <daveake> yeah don't do that
[15:54] <mikestir> that's the problem then. Add a linefeed, fix the crc and get rid of the spaces

[15:56] <daveake> Not seen one, but if you have 1 working it's not that hard to do 2
[15:56] <amell> ouch, xaben/hl1 appears to have landed in royston high street :)
[15:56] <amell> wondering if rocketnb
[15:57] <amell> rocketboy managed to recover before a shopper made off with it
[15:57] <N2NXZ> One working here,but took me awhile to do that,major rookie here
[15:57] <daveake> N2NXZ They way I did it was to halve the timer interrupt period, and service each transmitter every other cycle
[15:57] <mikestir> at least it landed on a crossing
[15:57] <mikestir> hope it pressed the button first
[15:58] <N2NXZ> So operating 2 modules using one code is not a good idea?
[15:58] <mikestir> it should be trivial, especially if you are using an interrupt to shift the data out
[15:58] <daveake> Why not? I did it; worked fine
[15:58] <mikestir> you could buffer up one bit per byte and run 8
[15:59] <amell> is anything still flying apart from the floaters?
[15:59] <N2NXZ> I tested another module and it conflicted with shift of the original RTTY
[15:59] DL7AD (~quassel@p5B097707.dip0.t-ipconnect.de) joined #highaltitude.
[15:59] <daveake> In my case it was an Arduino Mini Pro doing the transmission with 2 NTX2s, connected to a Pi over serial. The Pi built the packets and the AVR sent them
[16:00] <daveake> If you're using delays rather than interrupts, I suggest you get interrupts working first and then do 2 NTX2s
[16:00] <N2NXZ> Matching radios would be best most likely,but looking to add HF of some sort.Hard to find simple HF radios as easy to work as NTX2
[16:00] <amell> far as i can tell hdfld just died and isnt actually flying
[16:00] <daveake> Code is simpler that way
[16:00] <daveake> (interrupts)

[16:17] <mikestir> no. crc isn't an error correcting code (although I suppose you could correct a single bit error by brute force)

[17:28] <esculca> of the string

[17:34] <mikestir> tbh it probably doesn't matter as long as it's included in the checksum and habitat knows about it
[17:34] <mfa298> I was using the one arko (I think) linked to earlier and couldn't get the same result (I think it's probably using the wrong initial value)
[17:34] <mfa298> testing with http://www.zorc.breitbandkatze.de/crc.html also agrees on FAB0
[17:34] <mikestir> iirc it's a bit of a funny combination of polynomial and start value
[17:35] <mikestir> I think crc_ccitt normally starts with 0
[17:35] <mikestir> and the docs all call it crc16, which is a different polynomial
[17:36] <mfa298> the funny combination sounds familiar
[17:36] <esculca> can it be the complier?

[17:38] <mikestir> if you were running out of memory you'd either see data corruption, or it would crash (or both)
[17:38] <mikestir> because the stack would be hitting your buffers
[17:38] <mfa298> at this point putting your checksum code (or possibly all of it) on something like github or pastebin would probably be useful
[17:39] <mfa298> it's well worth learning to use something like guthub to manage code as well as it will (if you use it properly) keep revision history of all your changes
[17:39] <esculca> guys
[17:39] <mikestir> paste the crc function, the bit that assembles the data part of the sentence, and the bit that assembles the final full sentence with the crc appended
[17:39] <esculca> I found out what was happening
[17:39] <esculca> it's is green now :)
[17:40] <mikestir> what was it?
[17:40] <esculca> the gps_CRC16_function was made considering the string had the first 2 bytes as $$
[17:40] <esculca> so it was skipping this 2 first bytes
[17:40] <craag_Phil_M0DNY> No recovery for GILWELL
[17:41] <esculca> got it?
[17:41] <mikestir> esculca: yep I get e3a9 for that :)
[17:41] <esculca> the CRC has not being calculated on the entire string
[17:41] <mfa298> craag_Phil_M0DNY: :(
[17:41] <esculca> but rather the string minus the first 2 bytes
[17:41] <esculca> ok
[17:41] <mfa298> did it have contact info on it ?
[17:41] <esculca> good, thanks for the help
[17:42] <craag_Phil_M0DNY> mfa298: Yes it did.
[17:42] <esculca> guys, can I try it online now?
[17:42] <esculca> I am in Portugal
[17:42] <esculca> will it affect other payloads?
[17:42] <mikestir> should be ok. spacenear surely can't get any slower anyway
[17:42] <esculca> :)
[17:43] <daveake> ha
[17:43] <mfa298> and I think all the up/down flights are recovered/lost
[17:43] <mfa298> craag_Phil_M0DNY: have to hope for a phone call then (and hope it wasn't lost to a tree)
[17:44] <esculca> my previous launch I got that call 1 month later
[17:44] <esculca> from a police officer, in Spain
[17:44] <craag_Phil_M0DNY> Yep I will be hoping.
[17:44] <esculca> :)
[17:45] <craag_Phil_M0DNY> Every launch so far I've been insistent on seeing a new telemetry string before launch, this time I delegated it :/
[17:45] <SpeedEvil> :/
[17:46] <mikestir> did you delegate to that bloke that was asleep?

[18:51] <mattbrejza> 7
[18:51] <qyx_> ? 7
[18:52] <daveake> :)
[18:52] <LeoBodnar> vapour does not have pH i imagine
[18:52] <Boelle_DK> acid rain?
[18:52] <F1VJQ> it would if it was sulphuric acid vapour!
[18:52] <LeoBodnar> rain is not vapour duh
[18:53] <LeoBodnar> the question was about "water vapour"
[18:53] <Boelle_DK> sorry i asked
[18:53] <LeoBodnar> rain is liquid
[18:53] <mattbrejza> litmus paper and a camera?

[18:54] <LeoBodnar> maybe "partial pressure of sulfuric acid vapour" is better term
[18:54] <mfa298> jarod: reading back slightly, spacenear.us has a lot more data points on it than flightradar, and that's mostly done client side so maybe you just need a faster PC
[18:56] <Boelle_DK> or spacenear-us should not use the old googleapi
[18:56] <qyx_> Boelle_DK: like this? https://www.sparkfun.com/products/10972
[18:56] <qyx_> although it looks pretty complicated
[18:56] <Boelle_DK> qyx_: yep
[18:57] <LeoBodnar> I still claim vapour has no pH
[18:57] <Boelle_DK> vapour is still H20, just not as dense as in a glass
[18:57] <mfa298> Boelle_DK: well feel free to re-write it with the new api (it's a planned upgrade but the busy people that look after it have other more pressing changes that need to be done first)
[18:57] <MightyMik> it has a pH ... of 7
[18:57] <LeoBodnar> do you know what pH is reflecting?
[18:58] <Boelle_DK> no and that was still not the Q... the Q was how to messure how acid this less dense H20 is
[18:58] <LeoBodnar> I have to revert to wikedpedia
[18:58] <qyx_> Boelle_DK: yes and H2O has no, resp 7 pH
[18:58] <LeoBodnar> "In chemistry, pH is a measure of the acidity or basicity of an aqueous solution."
[18:58] <LeoBodnar> note "aqueous solution"
[18:59] <LeoBodnar> so unless you have ionised water vapour pH is meaningless
[19:00] <Boelle_DK> k
[19:00] <Boelle_DK> one idea scrapped there
[19:00] <LeoBodnar> it's an amount of H+ ions
[19:00] <mfa298> if it's in an aqueous solution can H2O have a pH ;)
[19:00] <LeoBodnar> well log and stuff
[19:00] <mattbrejza> clouds are water droplets though
[19:00] <mattbrejza> so you could measure the pH of the water in a cloud
[19:00] <mattbrejza> however, its probably easier to let it fall as rain then measure it
[19:00] <LeoBodnar> droplets or vapour?
[19:01] <Boelle_DK> lets define droplets etc....
[19:01] <mattbrejza> i thought they were droplets (taht line should have had a ? at the ned)
[19:01] <LeoBodnar> well pH of water vapour is minus infinity
[19:01] <Boelle_DK> i just thought it could be fun to messure it as it goes up and down... to tell how "clean" it is
[19:01] Aerospark (~aerospark@99.246.16.78) joined #highaltitude.
[19:02] <mikestir> you'd be better off measuring the concentration of $NASTY_GAS
[19:02] <LeoBodnar> droplets yes of course but question was about vapour
[19:02] <mattbrejza> well its not really something that will change over the course of the flight
[19:02] <mattbrejza> apart from n/a -> value -> n/a
[19:02] <Boelle_DK> its the value i was after... of course it will not change
[19:03] <Boelle_DK> if it will be so little it would not matter
[19:03] <mattbrejza> alothugh does acid rain become acid rain as it falls?
[19:03] <LeoBodnar> what if the value was 42?
[19:03] <LeoBodnar> what does it tell you?
[19:03] <mattbrejza> or does it become acid rain in the cloud

[19:03] <Boelle_DK> forget it... i did not ask to be made this much fun of....
[19:04] <mattbrejza> i thought my point is a reasonable question
[19:04] <mattbrejza> if you were to launch in rain would it get less acidic as you ascend?
[19:04] <LeoBodnar> perhaps both
[19:05] <LeoBodnar> acid vapour might be trapped on a different layer than cloud forming one
[19:05] <LeoBodnar> i assume it has been studied to death?
[19:05] <mikestir> an interesting experiment might be to launch in rain while collecting and measuring the ph of liquid water, while simultaneously measuring the concentration of sulphur dioxide in the atmosphere
[19:05] <Geoff-G8DHE-M> I understood it was as the water droplets collected SO particles from the air, so it could be within the cloud or on its way down, the vapour might have formed on the Sulpher particle in the first place
[19:05] <Boelle_DK> the reason behind my Q was out of pure interest in how clean the enviroment is....
[19:05] <mattbrejza> perhaps, but then so has the pressure/alitude relationship but people still fly it
[19:05] <Boelle_DK> it wold not be the only thing i thought of messuring
[19:06] <Boelle_DK> co2 would be another
[19:06] <Boelle_DK> particles

[19:06] <mattbrejza> good gas sensing is hard
[19:06] <mikestir> and power hungry
[19:06] <mattbrejza> or rather the shitty sensors from ebay dont do a good job
[19:07] <mattbrejza> i thought you could make a pH sensor easily from two different metals?
[19:07] <Boelle_DK> mikestir: your idea is along the lines of what i had i mind, but launch in rain?
[19:07] <mattbrejza> and then when you ascend through a cloud you should get condensation on it
[19:08] <mattbrejza> launching though a cloud should be enough
[19:08] <LeoBodnar> sensor probably needs self-cleaning cycle
[19:08] <mattbrejza> but youll only get one data point

[19:09] <Boelle_DK> could of course have more than one sensor and turn them on in sequense.. and have a mech. flap that covers them...
[19:09] <Boelle_DK> so at arround cloud base activate the first one...
[19:10] <mikestir> you could just collect little vials and test them on the ground
[19:10] <Boelle_DK> then the next a bit after etc,,, disabling the first one

[19:48] <LeoBodnar> you seem to want to know amount of acid in water droplets
[19:48] <Boelle_DK> LeoBodnar: it would tell me to say indoors when it rains
[19:48] <LeoBodnar> spectral analysis wil tell you just that
[19:48] <LeoBodnar> and lots more
[19:48] <Boelle_DK> and to have something on the roof that can handle PH that high
[19:49] <Laurenceb__> spectral analysis cant give you a nice number of pH
[19:49] <Laurenceb__> unless you add a dye perhaps..
[19:50] <LeoBodnar> you can back calculate pH by knowing the contents of dissolved chemicals
[19:51] <LeoBodnar> if knowing pH is such an important thing
[19:51] <Boelle_DK> well it was just an idea... i know i'm total cracked
[19:51] <LeoBodnar> it's much more practical than measuring pH directly

[21:05] <jcoxon> its not easy though
[21:05] <amell> was just looking at the commit log for fldigi, lots of new stuff
[21:06] <jcoxon> they have broken their rtty decoder
[21:06] <amell> did they make major changes?
[21:06] <jcoxon> its a lot worse

[21:07] <amell> ripped it out and put something else in?
[21:07] <F1VJQ> in my IT days we reverted to previous version...:-)
[21:08] <F1VJQ> whilst newer version tested/corrected
[21:08] <jcoxon> they changed some core code which has degraded the quality
[21:08] <jcoxon> but they haven't really noticed
[21:08] <jcoxon> honestly we are considering moving away from fldigi
[21:08] <myier> same here
[21:09] <amell> any alternatives now?
[21:09] <myier> F1VJQ: contestia, developed in 2005, that doesn't start well
[21:10] <mfa298> amell: there's mattbrejza's Java app which does rtty and turbohab
[21:10] <amell> well its a start, would need contesia at least
[21:11] <F1VJQ> myier age isn't an indicator...Windows 8 was developed recently...and that is MR2

[21:12] <mattbrejza> it is possible to have mor ethan one decoding program installed
[21:12] <amell> contesia is so good, i wouldnt be surprised if more people use it

[21:17] <myier> what's MR2?
[21:17] <amell> jcoxon: ok. so 50 baud rtty would be fine. did you report the 300 issue to upstream?
[21:18] <LeoBodnar> F1VJQ: yes APRS is there
[21:18] <LeoBodnar> did you increase the range in Contestia modem?
[21:18] <mattbrejza> why do we even need the latest version of fldigi? does it have anything added?
[21:18] <myier> celestia is used in fldigi? I'm not sure I understand the link between the two as written on contestia webpage
[21:18] <jcoxon> amell, oh 50baud isn't actually fine
[21:18] <jcoxon> it works but not very well
[21:18] <jcoxon> mattbrejza, very true

[21:19] <jcoxon> hence why we need a big discussion
[21:19] <myier> that'd be nice to be able to decode several signals at the same time too, but I've seen somewhere a software that does that already, maybe it was for windows only

[21:24] <Johnwulp> Hi, does somebody know on what freq. the b64 is?
[21:24] <mfa298> fldigi can do multiple streams within the same audio pass band, but I think it relies on everything using the same settings and things being in the same 4KHz - neither of which are common occurances in HAB

[22:16] <mfa298> myier: the downside is the increased path loss, the more restrictive duty cycle and fewer sensitive recievers for 868MHz

[22:17] <amell> laurenceb_: wow. if i power the LCD display off battery, the extra pixels dont appear. only happens via usb&.
[22:17] <myier> the fcdp+ for exemple receives less well than at 433?
[22:18] <mikestir> it's the antenna that's the main issue probably. a lot of people are using 2/70 ham antennas
[22:18] <mikestir> fcd, rtlsdr and anyone using an ssb capable scanner can probably tune 868 as well as 434, but they might not have the same antenna facilities
[22:19] <mfa298> the fcd pro+ is about the only decent receiver thats at a reasonable price and no decent comercial antennas. on 434MHz a lot of hams will have suitable receivers and there are lots of good antennas

[22:19] <myier> ok thanks for the info
[22:19] <F1VJQ> 434MHz capable stations are relatively abundant for tracking, where 868 equipped stations are very rare!
[22:19] <myier> where I am anyway, there's not much people to hear us
[22:20] <Lunar_Lander> and I think 2.4 GHz even rarer
[22:20] <Lunar_Lander> but I think people used that for video downlink
[22:20] <F1VJQ> and even less with 868
[22:20] <mfa298> mikestir: when you did your 868 flight did it also have a 434 tracker. Just thinking the stats between the two could be interesting
[22:20] <mikestir> yes it did. upu reported receiving the 868 on a scanner/whip on his windowsill for a lot of the flight
[22:21] <mikestir> but most people (including us) were using the 434 tracker
[22:21] <mikestir> the antenna was a dipole made out of copper tape attached to the side of the payload box
[22:21] <mikestir> I thought it would be rubbish
[22:21] <amell> what radio did you use for 868?
[22:21] <mfa298> I got the 868 as well although I think had to wait for it to get over the local hill (I was /A)
[22:21] <mikestir> amell: aor ar8200
[22:22] <F1VJQ> still green and I am now on the blue circle...may be one of the last greens... for the record, QRG is 434.496
[22:22] <amell> mikestir: i meant on the tracker PCB
[22:22] <F1VJQ> 412km
[22:22] <mikestir> oh, both trackers on that flight were rfm22b
[22:23] <mikestir> appropriate bands obviously
[22:23] <mikestir> the trackers were identical
[22:23] <myier> I thought it was too much unreliable with low temperature?
[22:23] <mikestir> a bit drifty
[22:23] <amell> i have two spare rfm69HW here. not sure what to do with them...
[22:23] <mikestir> fly them
[22:24] <amell> they are both 868
[22:24] <mikestir> I have some rfm69w modules for 434 and 868 but not done much with them
[22:24] <mikestir> the new tracker uses the bare chips and is much better
[22:24] <myier> I was thinking about buying the radiometrix TX3H if we're going for 868MHz
[22:24] <myier> anybody has experience with it?
[22:25] <amell> you wont get many trackers. most people dont have the aerials for 868
[22:25] <myier> experience with this emitter I mean
[22:25] <Lunar_Lander> also you can't run 868 full time
[22:25] <myier> the hardware
[22:25] <mikestir> Lunar_Lander: you can in one sub-band, but only at 5mW
[22:26] <Lunar_Lander> ah
[22:26] <mfa298> amell: sounds just right to do some #ukhasnet stuff with
[22:26] <myier> the increased power should allow for a faster communication, with a different mode than RTTY, maybe the 10% duty could be still all right
[22:26] <F1VJQ> amell or put them on ebay :-)
[22:26] <amell> mfa298: yes, maybe i see when it gets more mature...
[22:27] <F1VJQ> still receiving 434 at -0.1 horizon
[22:27] <F1VJQ> B-64
[22:27] <Geoff-G8DHE> myself, Have you taken a listen for B-64 yet ?
[22:27] <mikestir> the optimal solution is probably bpsk with turbo code
[22:28] NigeyS (~NigeyUK@cpc5-cdif15-2-0-cust763.5-1.cable.virginm.net) left irc:
[22:28] <myier> no, I'm installing the software on my laptop
[22:28] <Geoff-G8DHE> rather myier, have you taken a listen for B-64 yet ?
[22:28] <myier> but even with that, I have a building in the line of sight
[22:28] <Geoff-G8DHE> Ah right I thought you had already got that far.
[22:28] <Geoff-G8DHE> But its coming closer ....
[22:28] <myier> I'll see if the installation goes fine and CPU power is good, and I'll try to go outside maybe
[22:28] <mfa298> amell: the base of it is reasonably mature. Just needs more nodes and ideas of things to add (things like new sensors are relatively easy to add to the DB)
[22:28] <myier> I went that far on the fixed computer
[22:29] <mikestir> mfa298: the telemetry csv file for wggs1 (434) is 95.4KB, the one for WGGS1B (868) is 31.3KB
[22:29] <myier> at this speed, I don't have to hurry
[22:29] <mikestir> so that gives a good indication of how much more prevalent rxes are on 434, given that the 868 one was reported to be working well
[22:30] es5nhc (~tarmo@178.21.244.214) left irc: Remote host closed the connection

[22:32] <F1VJQ> green again! 417km
[22:32] <mikestir> I wonder if mattbrejza is about. I recall reading that turbo codes have actually been bettered by LDPC?
[22:32] <mattbrejza> depends on the frame length
[22:33] <mikestir> so do turbo codes win on short frames?
[22:33] <mattbrejza> also ldpc would require shit loads of space for the encoding matrix
[22:33] <mattbrejza> as i understand it
[22:33] <myier> how do you see your distance anyway F1VJQ?
[22:33] <fsphil> that's a lot
[22:33] <mattbrejza> should probably compare them :P
[22:33] malclocke (~malc@121-99-112-213.bng1.nct.orcon.net.nz) left irc: Quit: Ex-Chat
[22:33] <mattbrejza> as an example, the max frame length for ldpc is 6144 bits
[22:34] <mattbrejza> while dvb-s2 uses 32800
[22:34] <F1VJQ> myier it is shown in fldigi
[22:34] <myier> oh nice
[22:34] <mikestir> is your turbohab work based on lte?
[22:34] <F1VJQ> along with the elevation and bearing
[22:35] <mattbrejza> yea
[22:35] <mattbrejza> its interleaver is nice
[22:35] <myier> even if I can receive anything with gqrx, I won't be able to stream it to the dl-fldigi computer, would it be possible to record the sound, and replay it later, just to have some kind of history in the tracker map?
[22:35] <mattbrejza> the LTE turbo code is almost the same as previous standards though
[22:36] <mikestir> I want to have a look at some of this stuff because it interests me. I can probably implement some fairly heavy duty stuff on that ARM tracker I've got
[22:36] <F1VJQ> myier I cannot answer that question, but someone else maybe able to.... you could decode in fldigi and copy the received text window... that may be possible to paste into the back log
[22:37] <mattbrejza> the encoder is relatively trival
[22:37] <myier> in dl-fldigi
[22:37] <mattbrejza> it only becomes non trivial because the turbo code works on a bit by bit basis, but you store everything in uint8_t
[22:37] <mikestir> I'm particularly interested in capacity-approaching codes on 2.4GHz for live video
[22:37] <myier> it would then send data to the habitat
[22:37] <myier> old data, but since there is a date in it, is it a problem?
[22:38] <mattbrejza> you might as well just copy dvb-s2?
[22:38] <mikestir> yeah I suppose
[22:38] <mattbrejza> although even if turbo codes are 1dB worse than ldpc with longer frames, 1dB isnt that much
[22:39] <F1VJQ> 422km two greens and -0.2horizon

[22:41] <mikestir> mattbrejza: there's quite a lot of atv activity around here and I think a lot of it is dvb-s. I'm not sure if anyone has looked at doing their own modulators/encoders yet though
[22:41] <Lunar_Lander> ATV via satellite?
[22:41] <F1VJQ> myier if you can take a computer with fldigi you will be sure to receive, so long as your receiver is good
[22:41] <mikestir> I guess building a dvd-s2 modulator for terrestrial use is going to be a good first step
[22:41] <mikestir> Lunar_Lander: no terrestrial
[22:41] <Lunar_Lander> ah
[22:41] <Lunar_Lander> because you said DVB-S
[22:42] <mattbrejza> not suprised, have you looked at the specs for these things?
[22:42] <mikestir> they tend to use dvb-s rather than dvb-t because the 23cm band lies in the IF for a sat rx
[22:42] <mattbrejza> not exactly simple
[22:42] <Lunar_Lander> ah
[22:42] <myier> I can't have fldigi running on the laptop, it takes too much CPU
[22:42] <Reb-SM0ULC> mikestir: what kind of bw wre your thinking about for video?
[22:42] <mikestir> I reckon you can get reasonable quality H.264 at standard def down to under 1Mbps
[22:42] <mikestir> maybe 500kbps if it was gimbal stabilise
[22:42] <mikestir> d
[22:43] <Reb-SM0ULC> right
[22:43] <F1VJQ> myier then you may just be able to go and listen without decode
[22:43] <F1VJQ> myier it is still on 434.496
[22:44] <mikestir> mattbrejza: I looked at dvd-t2 for something else and I assume there is some commonality. I know it's not simple - would definitely require an fpga implementation
[22:44] <mikestir> *dvb-t2
[22:45] <amell> h264 is so so 80s&.
[22:45] <mattbrejza> you can always implement small parts of it
[22:45] <mattbrejza> for example turbohab is simplified from LTE because im not using MIMO or HARQ
[22:45] <mfa298> mikestir: looking at the lists of callsigns in the telemetry, 868 had 5 listeners, 434 had 23 (which included the same 5 that also heard 868)
[22:46] <amell> What about HEVC/H265
[22:46] <mattbrejza> 5 was good going not that long ago
[22:46] <mikestir> I'm surprised there were as many as 5 given that it was on a weekday
[22:46] <mattbrejza> got any hardware encoders handy for that amell ?
[22:46] <mikestir> ^^^
[22:46] <mikestir> h.264 is hard
[22:46] <mikestir> h.265 is no doubt harder
[22:48] <mikestir> also, if implementing dvb-s2 it would be sensible to use a standard sat rx
[22:48] <mattbrejza> are you getting ready for a possible rule change?
[22:48] <mattbrejza> or gonna NoV?
[22:48] <mikestir> not necessarily
[22:48] <mikestir> local club has a tracking mount on the top of a lighthouse
[22:49] <amell> lolz, 4K HAB video? i think theres some hardware chips out for HEVC now
[22:49] <mikestir> a dish could do quite well even on 2.4GHz ISM

[22:50] <mattbrejza> would need a pretty big dish
[22:50] <mattbrejza> do the maths and find out :P
[22:50] <Reb-SM0ULC> mfa298: more use of rsid could maybe help a lot, not that is was bad unmbers..
[22:50] <amell> youd probably have more luck fixing isee3.
[22:50] <mattbrejza> amell: encoder
[22:50] <mattbrejza> like even a pi can do h264 encoding
[22:50] <mattbrejza> but h265?
[22:51] <mikestir> mattbrejza: I did do the maths. It isn't going to do the full flight, but it was reasonable
[22:51] <mattbrejza> is that at 1Mbit?
[22:51] <mikestir> I think I assumed 500k at approaching the shannon limit
[22:51] <mattbrejza> although having the bitrate only gets you 3dB
[22:51] <mikestir> of course you could reduce the bitrate with altitude
[22:52] <mikestir> at mid altitudes there's nothing to see, and high up half the image is black
[22:52] <mattbrejza> you could get silly and start MIMO/beamforming

[22:52] <mattbrejza> although beamforming is probably not allowed at 10mW erp
[22:53] <mikestir> well, it would be if you met the erp bit
[22:53] <mfa298> Reb-SM0ULC: not sure how RSID would have helped. Those were the numbers of different listening stations over two different bands.
[22:53] <Reb-SM0ULC> mikestir: thinking packetized video a la ssdv or?
[22:53] <F1VJQ> compression on the blocks could reduce the amount needed to be sent... escape character followed by how many black pix
[22:53] <mikestir> no, I think mattbrejza's idea of just using dvb-s2 is a good one
[22:53] <mikestir> dvb supports packet data anyway
[22:54] <mikestir> the downlinks for sat broadband are just carried on dvb bearers
[22:54] <F1VJQ> 430.5km and another green
[22:54] <mikestir> however, this is not an easy project and I have no time!
[22:54] <mattbrejza> yea at altitude itll at least compres nicely

[23:02] <amell> arduino interrupts& anyone want to tell me why mine doesnt work?
[23:02] <mattbrejza> enabled them with sei(); ?
[23:02] <mikestir> it reckons it can achieve about 0.7dB over shannon limit
[23:02] <amell> ooh, never heard of sei()
[23:02] <mikestir> haha. that will be it then amell
[23:02] <amell> attachInterrupt(0, panicone, RISING);
[23:02] <mattbrejza> thats what you need on an avr anyway
[23:03] <mattbrejza> dunno about tarduino
[23:03] <mikestir> oh arduino weirdness
[23:03] <mikestir> so on a normal avr you just do ISR(vector_name){ stuff; } then set the relevant bit and call sei()
[23:03] <mattbrejza> is 0.7dB just the channel code?
[23:03] <mattbrejza> you then lose more performance with the sync, channel estimation etc
[23:04] <mikestir> that's just from the etsi doc. it claims 0.7 to 1 dB over shannon for the channel coding in awgn
[23:04] <mattbrejza> ah right
[23:04] <amell> its an interrupt routine which gets called when a button is pressed, on pin 2
[23:04] <mattbrejza> i think the lte turbo is about 1.6-2dB down on shannon
[23:04] <amell> pin2 should initiate a irq 1
[23:04] <myier> I have gqrx working on the laptop, I'm a bit disappointed by the fact that it needs pulseaudio to run and to eat 20% of my poor CPU
[23:05] <mikestir> presumably channel estimation/EQ is less of an issue for dvb-s because it doesn't need to worry about multipath
[23:06] <mattbrejza> i would have thought so
[23:06] <mattbrejza> carrier recovery then :P
