[10:18] <Heppie> @Viproz I am on the south coast near Portsmouth so I am aware that most launches are quite far away. I have got the raspberry pi Lora board from uputronics and will be operating portable. My plan was to use my 2m/70cm magmount but was wondering what people were using in general.
[10:22] chris_99 (uid26561@gateway/web/irccloud.com/x-zuceiayscweydeli) joined #highaltitude.
[10:24] <craag> Heppie: When portable a small yagi (~5 ele) if I'm able to point it, else I just stick with the magmount. I've used a colinear on a small mast but it often isn't worth the extra effort.
[11:42] <SA6BSS-Mike> the x50 x200 and x300 is commonly used as a base station antenna

[13:45] <Viproz> Does someone know what the two circles mean on a RS in APRS like here : https://aprs.fi/#!call=a%2FME836020&timerange=3600&tail=3600 ? They seem to be some kind of range but I don't understand why there is a small and a big one
[13:48] <daveake> From the aprs.fi blog ... "Flying stations having a "flying" symbol such as airplane or balloon will have two circles drawn around them. A larger blue circle indicates the sea-level horizon from the current altitude of the station. A smaller green circle indicates the area where the station can be seen at an elevation larger than 5 degrees."
[13:53] <Viproz> okay thanks, makes more sense

[21:52] <Hoshen_4Z7HKA> Hi!
[21:55] <Hoshen_4Z7HKA> I am getting this error when starting radiosonde auto_rx program,does any body know what that means?
[21:56] <Hoshen_4Z7HKA> 2019-01-03 23:51:03,056 INFO:Reading configuration file... 2019-01-03 23:51:05,391 INFO:Config - Tested SDR #0 OK 2019-01-03 23:51:05,399 INFO:Started Flask server on http://0.0.0.0:5000 2019-01-03 23:51:05,402 INFO:Telemetry Logger - Started Telemetry Logger Thread. 2019-01-03 23:51:05,563 INFO:APRS-IS - APRS Uploader Started. 2019-01-03 23:51:05,566 INFO:SDR #0 has been allocated to Scanner. 2019-01-03 23:51:05,656 INFO
[21:56] <Viproz> Hoshen_4Z7HKA, There is no error here ?
[21:56] <bertrik> I only see INFO messages
[21:57] <daveake> Was about to say ... looks like it's started ok
[21:57] <Hoshen_4Z7HKA> https://ibb.co/ggFhs48
[21:58] <Viproz> Oh okay, you probably didn't install rtl_sdr from source, let me find the link to the explanations
[21:59] <Viproz> Hoshen_4Z7HKA, https://github.com/projecthorus/radiosonde_auto_rx/wiki#32-rtl-sdr-from-source Don't forget to run "sudo apt-get remove rtl-sdr librtlsdr0 librtlsdr-dev" before building
[22:00] <Hoshen_4Z7HKA> Thanks! i will try it

[22:36] <michal_f> daveake, I see you added some UDP thingy to habdec? that's cool
[22:37] <daveake> Yeah just grabbed the UDP code from my LoRa gateway and made it into a simple program
[22:37] <daveake> udp <port> <message>
[22:37] <daveake> then call that from a 1-line shell script which gets called from your decoder
[22:38] <daveake> I've made 2 decoders - one just a headless Pi to put in the chase car boot; the other with a Pi touchscreen to also run a browser
[22:39] <michal_f> nice
[22:39] <daveake> This is all sooooooo much nicer than installing/using dl-fldigi :D
[22:39] <michal_f> https://www.youtube.com/watch?v=hCXeIi8ZSyo we have similar goals ;]
[22:40] <daveake> heh :)
[22:40] <daveake> I'm just using RTL SDRs at the mo
[22:41] <michal_f> probably that's good enough for a chase car
[22:41] <daveake> I think so
[22:42] <daveake> I rarely decode RTTY in the chase car because of the faff setting it up
[22:42] <michal_f> the dongle from rtl-sdr.com has bias-tee. I need to try make it work
[22:42] <daveake> Any intention to receive audio from an external receiver ?
[22:42] <michal_f> no, not really
[22:42] <daveake> ok
[22:43] <daveake> Just that I have an 817 in the car
[22:43] <michal_f> I don't even do typical USB demod
[22:43] <daveake> indeed
[22:43] <daveake> The main pain with dl-fldigi on the Pi is trying to get the audio working
[22:44] <michal_f> I never tried that actually. qgrx+fldigi always felt too bloated for that use-case
[22:44] <michal_f> at least for me...
[22:45] <daveake> Yeah, I used (hacked, for tuning) rtl-sdr
[22:45] <daveake> then fight pulseaudio
[22:54] <daveake> Putting it in a case ... https://usercontent.irccloud-cdn.com/file/wiMBwuBw/IMG_20190103_225352591.jpg
[22:55] <daveake> https://usercontent.irccloud-cdn.com/file/6JT7A6r3/IMG_20190103_225404928.jpg
[22:57] <michal_f> slick!
[23:01] <chris_99> neat, i'm assuming that's a screen, if so, what's the little display adapter board thingy you used?
[23:02] <daveake> Just a pi screen with its own adapter board, then pi 3 b+ on top
[23:03] <chris_99> ah cool, hadn't seen them before
[23:04] <daveake> I'll put a power bank in there, and get it to autostart the decoder and a browser
[23:05] <chris_99> nice
[23:06] <daveake> Later it would be good to use michal_f's decoder with the skygate thing I did for RPi, instead of dl-fldigi
[23:07] <chris_99> skygate thing?
[23:09] <daveake> A chase car app in Python, with LoRa and RTTY support
[23:09] <daveake> Basically, shows the telemetry and a big arrow pointing to the balloon
[23:11] <daveake> https://goo.gl/images/QGYHkJ
[23:13] <michal_f> what GUI toolkit is this? tk-inter ?
[23:14] <daveake> Gtk
[23:15] <daveake> They made me use it :(
[23:15] <daveake> Much prefer pyqt
[23:16] <daveake> Not tried tkinter
[23:18] <michal_f> I guess it's ancient compared to others
