[15:35] <alex___> cool someone is online
[15:36] <alex___> is anyone prepared to have a quick look at the research google drive doc for all things related to our high altitude balloon project
[15:36] <alex___> just to see if we've missed anything vital etc.

[15:42] <alex___> what is a yagi rotator anyway
[15:43] <craag> it's a motorised unit that turns a scaffold pole with a rotator on it
[15:43] <craag> they're nice in that you can automate them
[15:43] <alex___> oh but if we are using a small one we can just hold it
[15:43] <craag> but expensive and heavy
[15:43] <craag> yes
[15:43] <alex___> do you recommend a cheap yagi?
[15:43] <alex___> which*
[15:43] <craag> making one is cheapest - and easy
[15:44] <alex___> how easy
[15:44] <craag> plenty of guides around, any will work well enough
[15:44] <alex___> how do you connect it to the habamp/sdr
[15:44] <alex___> do you solder the connector on or something?
[15:44] <craag> yeah you'll want a bit of coax cable on it, with a connector on the end for the habamp
[15:44] <craag> others will be able to talk you through building one better than I can

[15:52] <alex___> but done
[15:53] <craag> one of the bits people find most daunting on the day is tying everything together
[15:53] <craag> so think about that beforehand
[15:53] <alex___> yeah
[15:53] <alex___> we also cant find the document for the CAA for 1017
[15:53] <alex___> 2017*

[15:54] <alex___> but it says 2016
[15:54] <alex___> any help?
[15:54] <daveake> That is the current one
[15:54] <craag> That one will be fine - they last updated it in 2016
[15:54] <craag> so it'll stay that doc until they update the ANO again
[15:54] <daveake> previous ones were 2005 and 2009
[15:56] <alex___> ah good
[15:56] <AndyEsser> the ANO is a nice bulky read for a plane journey...
[15:56] <AndyEsser> like War and PEace
[15:57] <alex___> is there anything missing from this rough spreadsheet

[16:03] <craag> entirely depends what altitude you want
[16:03] <craag> play with http://habhub.org/calc/
[16:04] <craag> you're compromising altitude vs cost of He/balloon
[16:05] <alex___> yeah cost of helium will be the issue
[16:05] <alex___> its more expensive than i first thought
[16:06] <alex___> unless im looking in the wrong places?

[18:01] <sascha_hemi> Hey,
[18:02] <sascha_hemi> Anyone from Germany here?
[18:05] <PE2BZ> Nein, Ich bin von Holland ;-)
[18:06] <PE2BZ> DL7AD seems to be online
[18:08] <sascha_hemi> Cool :)
[18:08] <sascha_hemi> Kannst du gut Deutsch=
[18:08] <sascha_hemi> =
[18:08] <sascha_hemi> )
[18:08] <sascha_hemi> ?
[18:09] <PE2BZ> Ich spreche ganz gutes Deutsch. Ich habe für 3 jahren das Tele-Satellit Magazin ubersetzt zum Hollandish
[18:11] <sascha_hemi> Ich möchte wohl auch mal einen Balloon starten. Ich weiß aber noch nicht ganz genau wie ich die Daten vom Balloon empfange. Also ich weiß das ein Arduino drin steckt aber wohin sendet der seine Daten und wo bekomme ich die Funk Module? :D
[18:13] <PE2BZ> Wenn Du einer Ballon startet, dan ist das drin was du drin steckt. Darf Arduino mit RTTY tracker sein, oder Pi in the Sky hardware mit eher RTTY oder LoRa Sender.
[18:14] <PE2BZ> Ist Ihrer English nicht so gut ?
[18:14] <sascha_hemi> es geht :D
[18:15] <PE2BZ> Es gibt viele Antworten hier wenn du im Englischer sprache die Fragen macht. So I will switch over to English.
[18:16] <PE2BZ> Are you radio amateur, or do you have any experience with radio reception other than the car radio ?
[18:17] <sascha_hemi> No, i doesnt have any experience but i have used some xBee Modules on my Arduino.
[18:18] <PE2BZ> Are you connected /related to anyone who is active with radio amateurism ?
[18:18] <sascha_hemi> yes, i am a member of a Hackerspace in the next city :)
[18:18] <sascha_hemi> And there are some Radio amateure
[18:20] <PE2BZ> So, if you send a balloon into space, what would be your goal ? Do you want it to send it´s position, follow it´s track and possibly find it back ?
[18:21] <PE2BZ> Or do you want to send images from space, with a built in or external camera ?
[18:22] <sascha_hemi> my goal is to send it´s position and follow it´s track without a camera
[18:22] <sascha_hemi> and hopefully find it back :D
[18:22] <PE2BZ> I would advice you to start with google translate and this website http://www.pi-in-the-sky.com/
[18:25] bertrik (~bertrik@rockbox/developer/bertrik) left irc: Quit: Lost terminal
[18:25] <PE2BZ> For receiving your own transmissions, if you have a laptop around, you should buy a rtl-sdr dongle, download some free software (like sdrsharp ) build an antenna yourself (easy and cheap) and start listening around. Get some experience with receiving, the settings on the software, routing audio from the receiver to decoder software (dl-fldigi HAB is needed to receive RTTY from HAB and post the locations to the web)
[18:26] rjsnyder (~rjsnyder@p54A44999.dip0.t-ipconnect.de) joined #highaltitude.
[18:27] <sascha_hemi> Ok, can i receive data from another balloon? so i can test the receiving before i start my own balloon project?
[18:28] <PE2BZ> You can and that is strongly advised :-) However, there are not that much RTTY hab flights around Germany. Most seem to use APRS but you can at least receive that with the same cheap setup also.
[18:29] <sascha_hemi> can i use this Receiver? http://www.ebay.de/itm/like/272510893804?lpid=106&chn=ps&ul_noapp=true
[18:31] <PE2BZ> https://s-media-cache-ak0.pinimg.com/736x/ef/d6/8b/efd68b4f497f95984d3cd9a498de0ac0.jpg
[18:32] <PE2BZ> You can, it´s the rtl-sdr but with a converter for HF reception build in. Takes a little more time to setup, but on the other hand, in the shortwave range 1.8 to 28.5 MHz there is daily RTTY transmissions to test your decoder setup
[18:33] <sascha_hemi> what setup would you recommend?
[18:34] <PE2BZ> May I ask what your budget is and if you have any other plans for receiving signals from around the neighbourhood ?

[18:35] <alex______> hi
[18:35] <alex______> ive narrowed down my options to 2 baloons - the hwoyee 350 or 500
[18:35] <alex______> in not too conver
[18:35] <alex______> im not too concerned with height*
[18:35] <alex______> (this is a preliminary launch)
[18:36] <alex______> is there any big reason why i should buy a 500 over a 300
[18:36] <alex______> it looks like the calculator says that for a target ascent rate of 5m/s
[18:36] <alex______> i would get 3000m higher for 0.2m3 helium extra
[18:36] <alex______> and seeing as the smallest helium cannistor i can buy is 1.8m3
[18:37] <alex______> which would be better, any opinions?
[18:38] <PE2BZ> for 28 Euro I would buy an rtl-sdr, but for around 5 times that price I would buy the Airspy mini
[18:39] <sascha_hemi> So i have two xBee Pro 868 Modules lying around...
[18:39] <sascha_hemi> the alternative is the 28 Euro rtl-sdr :D
[18:40] <PE2BZ> the xBee 868 modules come to no use for HAB flights I would say
[18:40] <sascha_hemi> hmmm :/
[18:40] <alex______> guys?
[18:40] <alex______> anything between the balooons?
[18:41] <PE2BZ> Alex I am not the Latex specialist ;-)
[18:41] <PE2BZ> I do receive and transmit signals and decode data and blow up my SDR by transmitting 100 Watt on 70 cm distance of my SDR ;-(
[18:42] <DL7AD> PE2BZ sascha_hemi. yep thats true
[18:43] <alex______> just as a general rule
[18:43] <alex______> is it better to go bigger or smaller with balloons
[18:43] <alex______> if they both fit helium/ascent rate/height desires
[18:43] stryx` (~stryx@unaffiliated/stryx/x-3871776) left irc: Ping timeout: 258 seconds
[18:44] <DL7AD> alex______: the bigger the higher you will get
[18:44] <DL7AD> but also expensive exponentially :D
[18:44] <PE2BZ> IF I would fly, that would be my first flight, I would go for the bigger balloon and underfill it to float. But I do not calculate, just what I would go for. After that I would try to find someone to help me to achieve what I want or convince me I want something else.
[18:46] <PE2BZ> DL7AD can you TX RTTY for sascha on UHF ;-) sascha where do you live ?
[18:47] <DL7AD> PE2BZ: really depends on in which district of berlin he lives :D
[18:47] <sascha_hemi> i live in northern Germany
[18:47] <PE2BZ> Distance to Berlin in KM ?
[18:48] <sascha_hemi> i live near Bremen in Lower Saxony
[18:48] <DL7AD> is it more or less than 50km?
[18:48] <sascha_hemi> much more than 50km :D
[18:48] <DL7AD> wow. thats too far
[18:49] <DL7AD> way too much
[18:50] <DL7AD> except if i would launch a balloon

[18:51] <PE2BZ> DL7AD Now we are thinking in solutions :-)
[18:51] <sascha_hemi> i´m thinking about transmiting the Data by GSM :D
[18:52] <DL7AD> Flelix (DL1SGP) would be more close to him. he lives somewhere near braunschweig
[18:52] <sascha_hemi> oh ok
[18:53] <DL7AD> sascha_hemi: you can do that. just you wont have any receiption above ~3km anymore.
[18:53] <DL7AD> so it's ok but not for live data
[18:53] <sascha_hemi> :/
[18:53] <DL7AD> for recovery its good

[18:54] <DL7AD> sascha_hemi: you could use a modified commerical weather sonde.
[18:54] <DL7AD> if you have knowledge about microcontrollers, you could do that
[18:55] <DL7AD> SP9UOB does this for some time
[18:55] <DL7AD> works excellent and you get them for free if you look for them.
[18:55] <sascha_hemi> Thats the reason why i´m here :D a member of a german facebook group found a weather sonde and now i´m interested in it
[18:56] <DL7AD> they are falling from the sky for free. the DWD doesnt look for them anymore
[18:56] <DL7AD> which one did you find?
[18:57] <DL7AD> the DWD use multiple types
[18:57] <sascha_hemi> he found an GRAW DFM-09
[18:58] <PE2BZ> Nice ! I located my first RS41 last thursday ;-) however, the house owner insisted to send it back himself and I got the parachutes.
[18:59] <DL7AD> sascha_hemi: eh... i think that one uses a differential GPS which is not a type to make use out of it
[18:59] <sascha_hemi> can i track weather sonde with an normal rtl-sdr? so if i found one i dont have to buy one :D
[19:00] <DL7AD> sascha_hemi: yes
[19:00] <DL7AD> some people do this
[19:00] <DL7AD> the RS-41 would be good. it has a real GPS receiver in it (ublox)
[19:00] <sascha_hemi> ublox are great
[19:01] <DL7AD> have a look for "sonde monitor"
[19:01] <DL7AD> that's a windows program which can receive the sondes
[19:01] <DL7AD> but don't ask me how to use it. i failed everytime.
[19:01] <PE2BZ> For the RS41 you can´t fail Sonde Monitor !
[19:02] <PE2BZ> Options, audio, select audio source.
[19:02] <DL7AD> PE2BZ: well its a matter of configuring the software
[19:02] <sascha_hemi> ok i will search for it
[19:02] <DL7AD> *correctly
[19:02] <PE2BZ> click RS41 on the top bar, than the green button to start
[19:02] <PE2BZ> Even I can do it ;-)
[19:02] <DL7AD> then i must be a noob :D
[19:02] <PE2BZ> NP :-)
[19:03] <PE2BZ> I can help you if you like ?
[19:03] <DL7AD> PE2BZ: i will come back if i get interested again
[19:03] <DL7AD> thx
[19:03] <PE2BZ> There are RS41´s in Poland
[19:03] <PE2BZ> but not all that much in Germany at the moment.
[19:03] <DL7AD> PE2BZ: mine is from poland. SP9UOB gave one to me
[19:03] <PE2BZ> Meppen has tested last year
[19:04] <sascha_hemi> does it give an online sonde monitor? :D
[19:04] <DL7AD> PE2BZ: i have friends who look for them regulary. maybe 5-10% are RS-41
[19:04] <DL7AD> sascha_hemi: yes.
