[13:45] <PE2BZ> SA6BSS-Mike, back again :-) Alt could not be in the E cell I guess because that´s the ¨always zero¨ for my ID 09 ?
[14:04] <SA6BSS-Mike> it did show 20m on one telemetry last night
[14:04] <SA6BSS-Mike> in E cell
[14:06] <SA6BSS-Mike> Then again , at what altitude over the sea are you ??after all your in the Netherlands, you could be under the sea, dont know how the script would ract on that
[14:08] <SA6BSS-Mike> are you at below 10-15m we could have pinpointed the problem
[14:09] <SA6BSS-Mike> PE2BZ: also, Davids script computer is down so no upload until he is back in the weekend
[14:09] <PE2BZ> rgr
[14:10] <PE2BZ> My GPS´es usually report between 7 and 14 m ASL from here
[14:10] <SA6BSS-Mike> bring it up to a tall building and try upload
[14:11] drsnik (~drsnik@gate3.ima.cz) left irc: Ping timeout: 245 seconds
[14:12] <SA6BSS-Mike> or closer to a 20m , maby a fishing rod up from the roof would be enough

[14:45] Action: PE2BZ is now considering the carbon fiber 10 m mast with wsrp in the middle and 2 x 5m10 wire standing on the roof at 52 m at the qrl. But no, not with this weather....

[15:22] <Astrobiologist> hello again
[15:41] <Astrobiologist> can anybody help me with RTTY on PITS?
[15:51] Astrobiologist_ (568a4bf2@host86-138-75-242.range86-138.btcentralplus.com) joined #highaltitude.
[15:51] <Astrobiologist> hello
[15:51] <Astrobiologist_> hello back
[15:51] <Astrobiologist> OK so at least IRC is working and I have the right nickserv password etc
[15:55] <nmcc> Hello Astrobiologist, I normally see about 700 shift.
[15:55] <nmcc> But why not actually use the dl-fldigi and remove one piece of uncertainty from the equation?
[15:58] <Astrobiologist_> RTTY should decode just fine in any RTTY decoder, it is plain vanilla RTTY if you see what I mean
[15:59] <Astrobiologist_> at the last conference people could decode it from Steve's balloon using RTTY decoders built into Kenwood handhelds etc
[15:59] <nmcc> But why not actually use the dl-fldigi and remove one piece of uncertainty from the equation?
[15:59] <Astrobiologist_> I am not sure it will build on my laptop.... but I will try now
[16:00] <nmcc> But why not just download dl-fldigi from the UKHAS website and remove uncertainty of compile from the equation?
[16:03] <nmcc> https://usercontent.irccloud-cdn.com/file/hhgE4u73/Screen%20Shot%202019-08-12%20at%2017.03.06.png
[16:04] <nmcc> Without actually firing a PITS up to be 100% sure, this is what my dl-fldigi is set to
[16:04] <nmcc> Are you getting the red stripes in the waterfall?
[16:10] <Astrobiologist_> more like great big yellow splodges
[16:10] <Astrobiologist_> however...
[16:11] <Astrobiologist_> it DOES decode on dl-fldigi (which installed really easily)
[16:11] <Astrobiologist_> so I am eating humble pi
[16:11] <Astrobiologist_> but that begs the question, why is the standard fldigi buggered.
[16:12] <edmoore> have you checked that they're set up identically in the modem config?
[16:13] <nmcc> Not a clue, I just know from Skycademy that that's the one to use. My expertise mostly runs to being pragmatic rather than diving down rabbit holes like compiling some software
[16:14] <SpacenearUS> New vehicle on the map: 03DC2EH-12 - 12https://tracker.habhub.org/#!qm=All&q=DC2EH-12
[16:14] <nmcc> However I do have it on my todo list to look at compiling dl-fldigi so I can remove some of the UI issues that drive me bonkers - like not saying WHEN it managed to decode something OK
[16:14] <Astrobiologist_> the Mac version of dl-fldigi is a joy to use, just unzip it and it runs
[16:15] <nmcc> Yup, that's where I'm at, iMac Retina and out on the road, MacBook Air
[16:15] <nmcc> However it won't talk to a USB GPS dongle for me, again, something on my todo list
[16:15] <nmcc> It took many readings to get my head around the PITS software
[16:16] <Astrobiologist_> I did the PITS set up with someone who was a more seasoned Pi hand
[16:18] <SpacenearUS> New position from 03ICT3 after 0318 hours silence - 12https://tracker.habhub.org/#!qm=All&q=ICT3
[16:18] <Astrobiologist_> edmoore I have just checked and the modem set up appears absolutely identical, which is why I am confused
[16:19] <edmoore> Rv?
[16:21] <Astrobiologist_> the receiver is a kenwood TH F7E connected to a USB soundcard plugged into the MacBook using a suitable voltage divider
[16:22] <Astrobiologist_> what I use all the time for APRS and ham radio etc
[16:22] <edmoore> have you hit Rv in the bottom right of vanilla fldigi?
[16:22] <Astrobiologist_> err no
[16:22] <Astrobiologist_> what does that do? Must admit I didn't notice it before
[16:23] <edmoore> does it make a difference if you decode it?
[16:23] <edmoore> sorry, does it make a difference to the decoding if you hit it?
[16:24] <Astrobiologist_> thanks edmoore I will try in a moment, we are just installing the camera to give that a go too
[16:39] <nmcc> Rather than having a voltage divider, can you not turn down the volume on the Kenwood?
[16:40] <nmcc> However, if you've not flown a PITS before and the UKHAS dl-fldigi is working for you, why not just stick to that for now?
[16:40] <Astrobiologist_> fldigi is working now!
[16:40] <Astrobiologist_> edmoore was correct, needed to have rv clicked.
[16:40] <Astrobiologist_> But what does rv do?
[16:53] <Astrobiologist_> hmmm I am still having a bit of trouble setting up dl-fldigi
[16:53] <Astrobiologist_> how can I make my receiving station appear on the map please?
[16:58] shiftplusone (~shift@unaffiliated/shiftplusone) left irc: Quit: Leaving
[17:05] <Astrobiologist_> OK, making some progress with dl-fldigi (latitude for my receiving station was missed)
[17:06] <Astrobiologist_> would it be possible please for me to get a payload document approved for my payload?
[17:06] <Astrobiologist_> I will be travelling back by train - we thought at a pinch we could try tracking it on the train and seeing if it uploads ok
[17:06] <nmcc> Yup, that's one of the other UI issues that irritate!
[17:07] <nmcc> You don't need to have it approved - and it would be in the #habhub channel to do that and you'll need the flight id
[17:07] <nmcc> Is your payload on the map now - what is it's callsign?
[17:10] <SpacenearUS> New vehicle on the map: 03pa0kn_chase - 12https://tracker.habhub.org/#!qm=All&q=pa0kn_chase
[17:10] <nmcc> You'll need to turn on the web upload and you should see that you get a green box with a telemetry string when it's decoded and at the bottom it says Uploaded successfully
[17:10] <nmcc> But all this assumes you've created at payload document
[17:10] <Astrobiologist_> yes, it is doing that now. the payload name is finhab
[17:10] <Astrobiologist_> payload document has been created
[17:11] <nmcc> There isn't anything on the map with that name - where are you?
[17:12] <Astrobiologist_> I am in Bath and I can see my receiving station (MOLVR)
[17:12] <Astrobiologist_> M0LVR
[17:13] <Astrobiologist_> but the payload won't appear on the map without a flight document - will it?
[17:14] <nmcc> Receiver ` Transmitter
[17:14] <nmcc> Nope, not even a little bit
[17:14] <nmcc> And right now, I can't see any upload attempts in the incoming processor for finhab
[17:14] <SA6BSS-Mike> No configuration doc for 'finhab' found

[17:15] <nmcc> So you aren't relaying your telemetry over the internet, which is required
[17:15] <Astrobiologist_> but it says "Uploaded payload_telemetry successfully"
[17:15] <nmcc> Under DL Client menu item in dl-fidigi, ensure you have Online checked
[17:16] <nmcc> Yeah, but when?
[17:16] <Astrobiologist_> every string is decoding green in dl fldigi
[17:16] <Astrobiologist_> online is checked
[17:16] <nmcc> OK, I can see the entries in the log tail now - it's that time of day when the sky is full of radio sondes so it's whizzing part

[17:17] <nmcc> Next step is to create a payload document
[17:17] <SA6BSS-Mike> you have PISKY in the paresrer name where it should be finhab
[17:18] <nmcc> What he said!!
[17:19] <nmcc> As I'm a bit OCD, I'd look to have your pisky.txt with your finhab as FINHAB
[17:20] <nmcc> And then you'll HAVE to Create new from existing and change your callsign from PISKY to finhab
[17:20] <nmcc> Which I've just done because it's easier
[17:20] <Astrobiologist_> I think I clicked on an old version of my payload document
[17:20] es5nhc (~es5nhc@96-247-29-85.dyn.estpak.ee) left irc: Ping timeout: 245 seconds
[17:21] <SA6BSS-Mike> and waht I can see you have 10 fields in you payload dock but tx 11 fields
[17:21] <Astrobiologist_> right, just so I can get my head around it: I think the pesky.txt is set correctly because all the decoded strings say finhab
[17:21] <Astrobiologist_> so does that mean I mis set it in the payload document only?
[17:21] <SA6BSS-Mike> its ok, just fix the http://habitat.habhub.org/genpayload/
[17:22] <SA6BSS-Mike> to matsh what you tx
[17:22] <Astrobiologist_> is the last in the list the most current?
[17:22] <SA6BSS-Mike> its a date on them? top one moste recent
[17:24] <nmcc> Date displayed in tiny grey print bottom right of each line
[17:24] <nmcc> The last one is the most recent
[17:24] <Astrobiologist_> OK, I think I clicked on the top one because the time looked right (but is actually CET)
[17:24] <SA6BSS-Mike> https://imgur.com/Oer80SQ
[17:24] <Astrobiologist_> so - bottom on the list, extra field now added - was battery current
[17:24] <nmcc> Have you got a DS20B18 wired in
[17:25] <nmcc> OK, yeah, battery current - 0.001 is what I get when I'm plugged in to psu
[17:26] <Astrobiologist_> flight document now recreated from corrected payload document
[17:26] <Astrobiologist_> how is it looking to you all now please?
[17:26] <edmoore> Astrobiologist_: Rv is short for reverse, it swaps the sense of the downmixed signal, so your upper freq becomes the lower freq and vice verse - it's equivalent to going from upper to lower sideband
[17:27] <nmcc> It's still not parsing - let me dissect the string and see what we need to add
[17:27] <Astrobiologist_> edmoore then a bit confused since my receiver is definitely set to usb
[17:27] <Astrobiologist_> mmcc many thanks
[17:27] <SA6BSS-Mike> Incorrect number of fields (got 11, expect 10)
[17:27] <edmoore> upper to lower or vice versa*

[17:29] <nmcc> OK, I've put the battery current in for you

[17:31] <nmcc> Nuclear - I'm pretty sure Bath Council Tax is doing a good enough job of htat
[17:31] <SA6BSS-Mike> lol
[17:31] <Astrobiologist_> mmcc thanks for editing in the battery current but I thought I had just done it? So have we been editing different versions?
[17:32] <nmcc> Nope, if we had, it would have appeared - it's usually a Save and then Save again issue
[17:32] <nmcc> I always edit the last one
[17:32] <nmcc> And I have some dead chicken entrails on my desk to help with this voodoo magic
[17:33] <nmcc> You can go in to the doc and edit the spelling of current to practise ;-)
[17:34] <Astrobiologist_> ok so can everybody track this now or just me?
[17:35] <nmcc> Only if you tell us what the frequency is, and from where I am, get it up high. So, no, not really
[17:35] <nmcc> The HAB receiver community generally tune in for a launch. For testing, you are on your own. So your laptop & receiver need to be on and on the internet
[17:36] <nmcc> But you could go for a jog around Bathampton Common with the PITS on a USB battery box or actual batteries and come back and see how fast you went
[17:39] <Astrobiologist_> this is a more "PITS On A Train" situation ;-)
[17:40] <Astrobiologist_> So speed might be quite good
[17:41] <Astrobiologist_> the frequency is 434.250
[17:42] <nmcc> I'm not going to hear you whilst you are on the ground - I'm in the Peak District, you'd need to be at least 5,000m for me to have a chance with my Yagi
[17:42] <nmcc> Where are you going to?

[17:50] <nmcc> OK. I'd turn the kit off and put it in a bag before you cross the M25 - no need to spend the night in the cells after an enthusiastic bobby at the train station takes an interest
[17:56] <Astrobiologist_> I've done APRS on a train before, and on a bus
[17:57] <Astrobiologist_> anyway, the it is running now, on battery! I will start off back to the station now. Will it work on the Android tracker or only if there is an approved flight document for the android tracker to fine?
[17:59] <Astrobiologist_> signing off for now, MANY THANKs for all your help!

[18:45] <PE2BZ> thunderbolts and lightning very very frightning
[18:56] <Astrobiologist> receiving finhab on a train!
[18:56] <Astrobiologist> is it uploading to habhub pls?
[18:58] <PE2BZ> YEs sir !
[18:58] <PE2BZ> 42 seconds ago
[18:58] <bertrik> cool
[19:01] <nmcc> How is Avoncliffe this evening?
[19:01] <PE2BZ> Astrobiologist, by the way, if fldigi is in mode RTTY and the radio is in USB you need to activate RV indeed. If you have fldigi in USB and not in RTTY it will still decode but then withour RV checked.

[19:07] <Astrobiologist> lovely train journey into the sunset, wife and daughter give me cover for handheld, jerryrigged cable etc
[19:10] <Astrobiologist> PE2BZ thanks but that leaves me very confused because for instance my radio has a RTTY mode which is symmetrical!
[19:11] <nmcc> No camera?
[19:14] <Astrobiologist> nmcc it doesn't seem to be working, possibly because it is an older raspian lite build. I have my colleague working on a second PITS with the latest raspian lite image
[19:14] <Astrobiologist> we also want to add other things like I2C accelerometer, magnetometer, ADC, and servos
[19:14] <nmcc> The PITS calls the built in to Raspbian raspistill command - but you do have to turn on the camera using raspi-config
[19:15] <Astrobiologist> when he has it all working (the I2C devices were all conflicting with each other's addresses) he'll clone the boot image for me and post it to me
[19:16] <Astrobiologist> nmcc thanks I'll try those commands later. I thought we did those though? as per the PITS manual?
[19:21] <Astrobiologist> feel free to listen out for finhab on 434.25 if you live near a train station en route!
[19:25] <nmcc> I'm at the top of Derbyshire ...
[19:28] <Astrobiologist> OK this is a bit strange, I can see my dl fldigi station too even though my laptop is turned off. it seems to be following me too?

[19:30] <ElectricFalcon91> Hi, I've gone through the wiki. I'm still a little unsure where to start. I've got experience with arduino, I have some with SDR (I've made a semi dodgy V dipole and got some okish NOAA). Whats the next best step?
[19:32] <bertrik> I guess to build a tracker, receive and decode it with an sdr

[19:33] <bertrik> maybe visit a launch
[19:33] <Astrobiologist> can REGAN receive finhab? that station is actually in range at my current "traintop" altitude!
[19:33] <ElectricFalcon91> Can I spoof some RTTY to test it? I feel I got a home station set up with SDR and dl-fldigi
[19:35] <Astrobiologist> ElectricFalcon91 I would buy a P.I.T.S kit, as I can attest, a day's work is enough to get it working as a basic tracker and indeed you can then receive it in your own home as a basic test

[20:23] <Astrobiologist> hello
[20:23] <SA6BSS-Mike> howd, I have tuned the Farnham web sdr
[20:23] <Astrobiologist> many thanks
[20:24] <SA6BSS-Mike> 434.250, what baud?
[20:24] <Astrobiologist> 300
[20:24] <SA6BSS-Mike> ok
[20:24] <SA6BSS-Mike> 7n2?
[20:24] <Astrobiologist> 8n5
[20:25] <SA6BSS-Mike> ok
[20:25] <Astrobiologist> 8n2
[20:25] <SA6BSS-Mike> Check
[20:25] <Astrobiologist> sorry,mistyped
[20:26] <Astrobiologist> RTTY tone spacing is more like 700
[20:26] <SA6BSS-Mike> ok
[20:28] <Astrobiologist> so this is a ground based test, from a vehicle (train). ostensibly the farnham SDR is now in range of the payload
[20:28] <SA6BSS-Mike> train wagon is probably a good chield, need to get closer
[20:29] <Astrobiologist> should pass very close which is why I thought it was worth a try
[20:29] <SA6BSS-Mike> fun test :)
[20:30] <Astrobiologist> yes it soak tests everything, also trying out the blackberry port of the android tracker
[20:30] Astrobiologist_ (~Astrobiol@94.197.120.142.threembb.co.uk) left irc: Remote host closed the connection
[20:32] <Astrobiologist> stationary at Basingstoke nol
[20:33] <SA6BSS-Mike> ok,
[20:33] <SA6BSS-Mike> best chance to hear it is probably when the train is broadside/window side to the rx site
[20:34] <Astrobiologist> yes I have opened repeaters and APRS from trains and buses similar!ly
[20:35] <Astrobiologist> but think of it as a sim of a distant or low powered payload
[20:37] <SA6BSS-Mike> gridsq puts the rx side on the north side of Farnham closer to the track
[20:37] <Astrobiologist> making closest approach to farnham sdr...
[20:40] <Astrobiologist> ...now. passing to the north
[20:48] <SA6BSS-Mike> kept my eye on the waterfall for the last 10 min and no trace of it
[20:49] <SA6BSS-Mike> there some slight qrm on the freq but nothing that would keep it from showing
[20:50] <Astrobiologist> ah b*gger
[20:50] <Astrobiologist> I wonder what the problem might be. maybe just a lot of train and buildings in the way
[20:50] <Astrobiologist> I might leave it running at home and then walk to the pub and see how much the signal gets blocked
[20:51] <Astrobiologist> many thanks for giving it a try
[20:51] <SA6BSS-Mike> yeah, fun fun:)
[20:51] <Astrobiologist> A9GPN might be another one to try - should get quite close to that one too

[20:52] <Astrobiologist> although it took two of us to get it working, and we got stuck a couple of times, the PITS is an amazing beast really. I could have flown a balloon this afternoon with a reasonable chance of success. I can also track trains it transpires
[20:53] <SA6BSS-Mike> I guess this is what you gona fly on that test/talk up in Finland?
[20:54] <Astrobiologist> yes hence the name
[20:54] <Astrobiologist> plus the payload has a big fin on it
[20:54] <SA6BSS-Mike> yep, guessed so
[20:54] <Astrobiologist> unable to make a free flight in the end but we got the money for a Helikite instead
[20:55] <Astrobiologist> nice but not high enough for my liking
[20:55] <SA6BSS-Mike> there was this youtube video of a guy posting of a handhled gps-aprs tx that was set to tx on a timer, he got a few packets through, probably more of them now on youtube
[20:56] <SA6BSS-Mike> how hogh do you get on one of those Helikite?
[20:56] <SA6BSS-Mike> *high
[20:57] <Astrobiologist> depends on the wind, the weight of the tether, and the weight of the payload
[20:57] <SA6BSS-Mike> ok
[20:57] <Astrobiologist> with a good wind, the lifting body shape of the helikite could lift to several thousand feet including tether mass
[20:58] <Astrobiologist> but without wind only a few hundred feet
[20:58] <SA6BSS-Mike> whn is this happening?
