[07:27] - he decided to install a horusgui windows version on a lapotop, and try to use it at the field to get position. [07:27] have you any practical tipps/tricks, to prepare such an excursion/hunting? [07:27] To take attention to the balloon material, if it can find it. The question is, what happened to burst it. Before this event it was stable fliyng 2 hours on 10 km high... [07:28] PE1MIU (~PE1MIU@89.30.156.163) joined #highaltitude.

[07:33] speed [07:38] its a good question [07:39] on the ukhas map, on the Telemetryu graph we can see, lost the altitude [07:40] clear skyes, no clouds? [07:40] from 10 km to 6800 m approx some minutes [07:40] that sounds like aburst [07:41] balloon used? [07:41] I dont kno, I was far away, more than 200 km [07:41] what balloon did you use? [07:41] maybe ask SP6NEI [07:42] ah, it wasnt you relesed it [07:42] it was his balloon, landing yesterday in north Hungary [07:42] ok [07:43] I try to force my friend, live not far from ther,e try to visit the landing site [07:44] Small latex balloon [07:44] so a regular latex burst then, they will happen randomly whn floating them [07:47] Assuming no parachute, so either white or transparant remains of the balloon, which would not be that big. [07:47] so, is it a frequent event with latex? [07:47] yes [07:48] SA6BSS-Mike, your tracker had some speed :-) [07:48] its not that fast today, yesterday it was up to near 200kmh [07:48] but it did make it to central Turkey within 24h [07:49] but tjanos , if still transmitting and the expectation that it only travelled 400 m from the last fix given the high descent rate I would first go to the last spot and listen for the signal in 4fsk. If they donīt receive it could either be further away or even did break when landing. [07:50] SA6BSS-Mike, diy balloon ? [07:50] no, Grabo, satain White this time :) [07:50] 4 gram payload ?

At the moment it is abouve southern France. I like in northern Italy. How to predict when it will be in my range? Could you help me? [10:35] btw: I don't remember the meaning of the green circle. 10° elevation I guess? [10:35] *I live in northern Italy (well, i like it too but it is another story) [10:39] malgar: 5 degrees [10:40] as for KD2FOU, it's probably transmitting on 20m or 30m WSPR [10:41] pressing the hysplit button on its pane in the table on the left gives some idea of where it may go [10:58] ah, I thought 434 MHz rtty [10:58] what kid of balloon is it? amateur? [10:59] no, pretty much all the long-duration floaters transmit on either APRS, or HF using WSPR [10:59] yes, its an amateur balloon [11:00] I'm reading about WSPR [11:01] I'm just searching something "easy" for me to return in the "business" :P [11:01] if its transmitting WSPR, it will be received by the WSPR network automatically, and then whoever launched the balloon will be running a script to scrape data from wsprnet and upload it to habitat [11:01] or to APRS [11:04] The best for me would be a classical latex balloon transmitting on 434 MHz rtty, easy for my yagi, sdr pen and dl fldigi [11:05] yes well, you can hope [11:05] not as many flying RTTY any more [11:07] what's the most used for beginners latex balloon project? is there a page on wiki.ukhas about the actual widespread systems? [11:08] I'm about ~7-8 years behind [11:08] a lot of beginner groups are using the pi-in-the-sky kits, whith transmit LoRa and RTTY, some use reprogrammed RS41s, which transmit RTTY, APRS, or 4FSK [11:08] in the US most still just ue APRS [11:09] anything on the map with a -11 or some other number on teh end is probably arriving via APRS [11:09] not arduino anymore? [11:09] anything with a -4FSK is using the horus 4FSK mode, everything else is possibly using LoRa or RTTY [11:09] arduino is an IDE, supporting many different platforms [11:10] sure [11:10] so sure, people might be using the arduino IDE, but targetting a custom board, or something else [11:10] ok [11:10] the -4FSK payloads are usually using reprogrammed RS41s [11:10] radiosondes [11:13] New position from 03N4XWC-1 after 0310 hours silence - 12https://tracker.habhub.org/#!qm=All&q=N4XWC-1 [11:14] is dl-fldigi still useful? [11:15] for RTTY payloads, and some rarer payloads using other modes, sure [11:15] there was some talk about it yesterday, it's getting a bit problematic to get it to compile [11:16] sure is [11:16] its basically abandoned [11:18] I remember a wonderful SSDV balloon I tracked. With the images slowly appearing line by line in front of my eyes [11:18] there are still many flights using SSDV, but a lot are via LoRa now [11:20] ok, I'm reading pages about it [11:20] If you want to suggest me something to keep me updated.. [11:20] if you search for LoRa nowdays, really all you will find is information about LoRaWAN [11:20] something to read [11:20] which is a routing layer on top of the LoRa modulation [11:20] ok [11:20] the LoRa payloads i'm talking about do not use that routing [11:21] they just use the modulation and send raw packets containing either an ASCII string (just like what would be sent via RTTY), or a SSDV packet [11:22] as for resources on this... i'm not so sure. its all widely dispersed [11:22] daveake probably has some blog pages on the LoRa stuff [11:23] and its his 'ground station' code that most (all?) receiver stations are running [11:33] it would be nice to keep some narrow band modulation going on floaters still [11:33] Chrischan8 (~Chrischan@ip5f5aff78.dynamic.kabel-deutschland.de) joined #highaltitude. [11:33] like RTTY, DominoEX, Contestia or even Hell [11:35] LeoBodnar: my 4FSK mode running at 50 baud would probably work well [11:35] easier for autonomous receivers to pick up anyway [11:35] is it Gaussian? [11:36] its whatever the hell you can generate [11:36] do I need a special chip for LoRa? Can't I receive and decode the signal using an sdr pen + pc? [11:36] malgar: hahaa now you hit the nail on the head with LoRa [11:36] there's no SDR demod thats worth a damn [11:36] it's a proprietary closed source product [11:36] gr-lora exists... but doesnt really work [11:36] I don't get this gravy train ride [11:36] but it's patented all over [11:37] I mean the whole IoT obsession with LoRa [11:37] i think it just comes down to supply of chips [11:38] like, sigfox exists, is basically just narrowband FSK and performs just as well [11:38] but it hasnt really had the uptake that lora has [11:38] Semtech has the nuclear button of LoRa ob CEO's desk [11:38] *on [11:39] LeoBodnar: anyway, the 4FSK demod is designed for non-gaussian-filtered FSK, but at 100 baud.... ehh [11:39] doesnt matter so much [11:39] it's like FLARM [11:39] FLARM is a travesty [11:39] the fact that a single manufacturers product is mandated in some countries is ridiculous [11:40] and that there is no open standard for that kind of close-range collision avoidance thing [11:40] its insane [11:40] ok VK5QI I just thought maybe decoder is fine-tuned for specific pulse-shaping [11:41] nah [11:41] the FSK demod is fairly generic, i use the same demodulator for radiosonde decoding, with the various combinations of GFSK and FSK that are out there [11:41] someone's ISM Arduino project is suddenly pushed by gov for enforced use in feel-good collision avoidance [11:41] it a non-coherent FSK demod, and performs to theory [11:41] ta [11:41] well, implementation loss is <0.5 db [11:42] references you would probably need are: https://github.com/projecthorus/horusbinary_radiolib and https://github.com/projecthorus/horusdemodlib/wiki/5-Customising-a-Horus-Binary-v2-Packet [11:43] saved for later, cheers [11:47] its probably not going to be as performant as contestia... but it also doesnt run at as slow a baud rate (or with such a slow coding rate) [11:48] but the benefit is the demod has excellent frequency estimation, so will lock on to a FSK signal in the passband reliably [11:50] https://ukhas.org.uk/guides:tracking_guide you could update this.
