[09:30] <TimMc_> good evening :)
[09:31] <TimMc_> heh
[09:31] <Astrobiologist_> So where are you TimMc_ ?
[09:31] <TimMc_> I'm in Melbourne, Australia
[09:32] <TimMc_> I'm just setting up a second radiosonde_auto_rx
[09:32] <Astrobiologist_> I think you will be out of range of ICSPACE 4 & 5 then ;-)
[09:32] <Astrobiologist_> Ah well I think I will be out of range of you too!
[09:32] <Darkside> hey TimMc_ - what area?
[09:33] <Astrobiologist_> Although I am quite interested in trying to make my own APRS TX one day (not legal airborne in U.K but le
[09:33] <Astrobiologist_> But legal most places elsewhere airborne)
[09:33] <TimMc_> still Ringwood for now until I can get permission to setup elsewhere further east
[09:33] <Darkside> ok
[09:33] <Astrobiologist_> Dark side morning
[09:33] <TimMc_> I could set one up near Sale

[09:38] <edmoore> hello ol
[09:38] <Astrobiologist_> Good morning Ed
[09:38] <Darkside> TimMc_: some of those will be people that were trying to track the Project Horus launch from Adelaide
[09:39] <Astrobiologist_> I was looking at the APRS specification for building packets.... A bit depressing really
[09:39] <edmoore> just make sure you set it to WIDE2-2
[09:39] <edmoore> to make sure it gets through
[09:40] <Astrobiologist_> It was more about the fussy bit timing etc
[09:40] <Astrobiologist_> This is for possible Finland flight
[09:41] <Darkside> edmoore: troll
[09:41] <edmoore> for which platform are you implementing this?

[09:43] Astrobiologist2 (~yaaic@213.205.240.133) joined #highaltitude.
[09:43] <Astrobiologist2> edmoore I dropped out there for a moment
[09:44] <Astrobiologist2> the easiest thing to do would be to use PITS
[09:44] <edmoore> there is presumably an aprs implementation already for pits
[09:44] <edmoore> daveake: ?
[09:44] <Astrobiologist2> but it is a bit difficult since I need to homebrew it to add relays and other things
[09:44] <edmoore> you could at least use it as a ref if you want to fun of implementing it yourself
[09:44] Astrobiologist_ (~Astrobiol@213.83.108.162) left irc: Ping timeout: 250 seconds
[09:44] <Astrobiologist2> yes PITS does APRS already
[09:45] Astrobiologist (~yaaic@188.72.99.199) left irc: Ping timeout: 245 seconds
[09:45] <Astrobiologist2> define "fun"!
[09:45] <edmoore> learnin
[09:46] <Astrobiologist2> since APRS is FM and the HX1 and NTX2b are FM transmitters it should be straightforward
[09:46] <Astrobiologist2> however the bit timing etc seems fiddly
[09:46] <Astrobiologist2> I have a Pyboard which I am quite fond of
[09:46] <Astrobiologist2> might try that in parallel with a Pi Zero if I have time

[10:02] <Astrobiologist_> Right sorry about the duplicate IDs, I find one or the other keeps dropping out and then I need to retaliate with NickServ every time
[10:02] <Astrobiologist_> Retaliate
[10:02] <Astrobiologist_> REVALIDATE
[10:04] <Astrobiologist_> Anyway, like I was saying, PITS is really lovely but I was biting my lip about how many other components on the board I would have to recapitulate myself if I tried to build one myself
[10:04] <Astrobiologist_> But APRS etc is tricky, it just shows how excellent PITS is

[10:14] <Astrobiologist_> What is the latest launch time for IC SPACE 4 please?
[10:16] <SA6BSS-Mike|2> 11-15 utc
[10:17] <SA6BSS-Mike|2> I asume Medad will log in here prior to launch
[10:17] <Astrobiologist_> Many thanks Mike. I will try to get to an open area to listen in but neither Medad or I heard much last time from within London itself
[10:18] Action: PE2BZ tested a 2.7 V 500F chinese Supercap on a tracker. 160 gram of weight, lasted a full 50 minutes :-(
[10:18] <SA6BSS-Mike|2> PE2BZ: wow!
[10:19] <SA6BSS-Mike|2> had one og my low power tracker run for 45sec on a 1F cap
[10:19] <Darkside> PE2BZ: your 600g Hwoyee launch - what payload weight did oyu have on that, and what altitude did it reach?
[10:19] <Astrobiologist_> You could have flown a gerbil with a leather pilot's jacket on a dynamo wheel with an oxygen mask for 160g
[10:20] <Astrobiologist_> ( I am big on gerbil welfare)
[10:21] <PE2BZ> Darkside 39040 m altitude and I am checking the weight one moment
[10:21] <SA6BSS-Mike|2> Astrobiologist_: find a hill and bring a fishing rod and get you antenna a few meters of ground, that would make a differnce, but its not the beast time of year sitting out side for a few hours!
[10:21] <Darkside> PE2BZ: jeezuz. i want to try that lol
[10:22] <Astrobiologist_> My lab is on the 11th floor and has a glass frontage, I picked up ICSPACE 3 and 4 fleeting from inside
[10:23] <Astrobiologist_> I think the main problem is how cluttered the horizon is in London
[10:23] <SA6BSS-Mike|2> oh nice, you have access to the roof?
[10:23] <SA6BSS-Mike|2> ok
[10:23] <SA6BSS-Mike|2> Wife is foing to london in a couple of hours (by the way)
[10:23] <Astrobiologist_> No, I suppose I could ask one day but there is a huge air con and hepa filtration plant so the whole are is restricted
[10:24] <SA6BSS-Mike|2> ok
[10:24] <Astrobiologist_> Quick Mike make her download the android app
[10:24] <PE2BZ> Darkside maybe you have seen this allready , preparations on https://photos.app.goo.gl/DU6F6any94o21KWi8
[10:24] <SA6BSS-Mike|2> hehe Il try to convinc her !! but I already know the awnser :)
[10:24] <Astrobiologist_> Smuggle an SDR onto her laptop
[10:25] <SA6BSS-Mike|2> she is probably going to fly staight over the balloon(s) on her way
[10:25] <Astrobiologist_> Even better, nobody said you can't RX from an airplane
[10:25] <SA6BSS-Mike|2> would probably work to some extent!
[10:25] <Astrobiologist_> Intriguing thought actually...
[10:26] <SA6BSS-Mike|2> indeed
[10:26] <Astrobiologist_> Airborne digipeating for APRS is the thing that springs to mind, where airborne 2m is legal
[10:26] <SA6BSS-Mike|2> activate Plane chase
[10:27] <Astrobiologist_> Actually that is how Jonathan tracks down payloads
[10:27] <SA6BSS-Mike|2> eveywhere but UK , France and one more ...
[10:27] <Astrobiologist_> Using helicopter APRS!
[10:28] <Astrobiologist_> Back in a mo
[10:29] <Darkside> PE2BZ: i love the little parachute, where did you get that?
[10:30] <Darkside> also what kind of ascent rate did you target? (i'm guessing low!)
[10:31] Astrobiologist_ (~Astrobiol@92.40.248.77.threembb.co.uk) left irc: Remote host closed the connection
[10:36] <PE2BZ> 2 m/s with RS41 without the hard cover (so not the newer P series, but the ¨older one¨ buth with the hard cover removed, and 10 gram for the parachute. So, the kingsday flight with hard cover was 140 gram with chute on the same 600 gram balloon (38986m) this one was about 120 gram with chute (39040m)
[10:37] <PE2BZ> Chute is this model https://www.meteorologyshop.eu/en/balloons/radiosonde-balloons/368/meteorological-parachute-pc-055
[10:38] <PE2BZ> That´s where de Bilt flies all rs41´s with (and previously the RS92) so they come by mail, boxed, from radio amateurs over here after recovering.
[10:38] <Darkside> ok
[10:39] <Darkside> hmm
[10:39] <Darkside> i wonder if they ship to australia
[10:40] <Darkside> urgh my IRC window is screwed up with some UTF-8 stuff
[10:40] <Darkside> PE2BZ: what was the ascent rate?

[10:42] <PE2BZ> both aimed for 2 m/s
[10:44] <Darkside> ok
[10:45] <PE2BZ> G8FJG reported a mx horziontal speed for the record flight of 250 km/h btw
[10:45] <Darkside> hah
[10:45] <Darkside> nice
[10:46] <Darkside> hmm getting approval to launch that kind of flight could be interesting
[10:47] <Darkside> air traffic control have been paying attention to our flights recently
[10:47] <Darkside> and they like it if we have a good idea of where the flight is going to go
[10:47] <Darkside> for somethign like that, it would be much more uncertain
[10:48] <Darkside> i suspect i'd only get away with it if i used a <50g payload, and did it as a non-NOTAM'd launch
[10:49] <PE2BZ> With < 50g payload you could get to >40 km :-)
[10:49] <Darkside> sadly my experience with RS41s in just a foam enclosure has been very bad
[10:49] <Darkside> i still dont get how you dont have issues
[10:50] <Darkside> its weird
[10:50] <PE2BZ> We have flown bare PCB´s with only the battery in bubble foil....
[10:51] <Darkside> yes, this is what i dont get..
[10:51] <Darkside> i have done flights in the foam, and have had them fail
[10:51] <Darkside> my code is a fairly simple fork of the RS41HUP Code, with the 4FSK stuff
[10:51] <Darkside> its transmitting with 100% duty cycle
[10:51] <Darkside> so... what the hell
[10:53] <Darkside> maybe vaisala are sending us the bad sondes :P
[10:55] <Astrobiologist2> any news on ICSPACE4 please?
[10:56] <PE2BZ> Darkside no message on the sondes like ¨if thawed, do not refreeze again¨ ?
[10:56] <PE2BZ> No news, no new position on the map for ICSPACE yet
[10:56] <Darkside> PE2BZ: lol no
[10:57] <Darkside> makes me wonder if i have been uing a bad batch!

[11:43] <Astrobiologist2> ICSPACE sorry to hear that. How badly snarled is it? It might free itself later, in which case we could listen out for it. Or you could go back with a spiritofair pole or similar to try to unsnarl it. Did that with a kite once
[11:43] <TimMc_> Is there rs41 firmware? got a blackmagic probe handy for stm32
[11:44] <ICSPACE> Astrobiologist2 Check the url.
[11:44] <Darkside> TimMc_: yep, theres a few...
[11:44] <Darkside> this is my fork: https://github.com/darksidelemm/RS41HUP
[11:45] <Darkside> which we use for project horus balloon launches
[11:45] <Darkside> https://github.com/darksidelemm/RS41FOX and a foxhunting beacon
[11:45] <Darkside> just note that you will need to run within LIPD band limits, i.e. <=25mw, within the 434 mhz ism band

[17:04] <Astrobiologist> if anybody is on who listened to ICSPACE 5 earlier, there is something I would like to check
[17:04] <Astrobiologist> does it broadcast pips alone, i.e nothing else, if it doesn't have GPS lock?
[17:07] <Medad> well thats what it does. It send pips when it does not get a good lock of at least 6 satallites.
[17:07] <Medad> Bad idea it turns out
[17:07] <Astrobiologist> thanks Medad
[17:08] <Astrobiologist> OK, basically for your launches when you say you are testing outside or prepping for launch I start hearing pips
[17:08] <Medad> But when it was launched and within your range, it was transmitting regularly.
[17:08] <Medad> Most likely us
[17:08] <Astrobiologist> yes but I tend to hear the pips first, on the ground
[17:09] <Medad> approximately once every 3 seconds when it did not have a lock

[17:29] <Medad> I think it should still have battery. It should work for at least 16 hours
[17:30] <Astrobiologist> would you like to make an APRS version? I might need to launch from Finland...
[17:33] <Medad> Currently we are thinking of a lora tracker instead(connected to the Things Network) No plans for APRS at the moment.
[17:34] <PE2BZ> Medad the terrain has a chance of a wet landing, no signal is received from 6 km distance, and chances are that it passed or did not pass the river once or twice so no-one is going to look for it now from here at this moment.
[17:35] <Medad> No worries at all

[17:47] <Medad> There was so strong a wind when we launched ICSPACE4 that it just failed to clear the trees. We gave it around half a km to clear the trees but due to a slight downdraft, it just could not rise. The net lift was 2 grams
[17:47] <Medad> There is a storm blowing at the moment it seems in the UK
[17:48] <Medad> Note to self. avoid rain during a launch and WIND!
[17:54] <Astrobiologist> Medad it is like lots of baby turtles and some get eaten by skuas etc before they reach the water

[23:36] <Medad> What state is the balloon in? did it burst?
[23:37] <Medad> or did it leak out through the valve?
[23:37] <PD3JO> sonde looks good ,but have drifting on the ground ,with the stormy wind its stops on a fence
[23:38] <Medad> ICSPACE5 already suffered a bashing before launch when we dropped it due to the very strong wind
[23:38] <PD3JO> no not burst a very small leake , ican not hear where
[23:40] <Medad> How long did it take you to find the balloon?
[23:41] <Medad> I see that you have traveled quite a distance to find the tracker
[23:41] <PD3JO> it was difficult to walk with the halfull balloon in the strong wind :)
[23:41] <Medad> Same problem we had at launch here in London!
[23:43] <Medad> How did you know that the tracker was still alive? did you hear pips from your tracking station?
[23:44] <PD3JO> a long time to find him ,first time just before dark , i heard a signal but before i make a direction ,the receiver accu was empty
[23:45] <PD3JO> later i go back ,now with laptop
