[10:23] <Frontier> HELP - We are a commercial company who want to send App controlled toy into space and control it from the ground using our mobile APP. We are looking for someone with some technical expertise's to help us with this project. We have a team of software and hardware engineers to assist with the project and offer support. We need to ensure we take all the appropriate safety measures and are compliant with the applicable rules and
[10:26] <Frontier> We are also happy to financial compensation for your time. If you are interested then please email me at damien@lovense.com. Due to the nature of this project only people over the age of 18 should apply. Thanks.
[10:28] <chris_99> what's the toy out of curiosity?
[10:29] <Darkside> lol
[10:29] <Darkside> go look at lovense.com
[10:29] <Darkside> and you will see

[10:32] <Darkside> Lahti: uhmmmmmm
[10:33] <Darkside> maybe?
[10:33] <Lahti> within an hour the Meteorological Institute leaves sonde

[10:36] <Darkside> im wondering if they have upgraded the GPS chipset to a ublox 8-series
[10:39] <daveake> Ah, so that's what they meant by "Remote controlled object in space" when the emailed me last year ....
[10:39] <Lahti> and the picture below left me sonde https://www.google.com/maps/@60.814382,23.4980452,219m/data=!3m1!1e3
[10:41] <Lahti> The R-series dropped close to this, but 50cm of snow, I'm not gushing :D
[10:42] <Darkside> right
[10:42] <Darkside> i guess ill wait :-)
[10:42] <Darkside> but yeah, am interested to see if they upgrade any of the components on the board, since a few of them are probably getting close to EOL
[10:45] <Lahti> In the spring, the hunt goes again, here 24h station https://aijaa.com/aE8Wt6
[10:49] <Lahti> also follows other Finnish stations, we have a great team here :)
[10:49] <Darkside> so i've noted!
[10:49] <Darkside> lots of auto_rx stations up ther e-)
[10:49] <Darkside> :-)
[10:50] <Darkside> so do you just recover the ones that have landed, or do you go out chasing them?
[10:51] <Darkside> i like going out and chasing them while they are in there, and watch them land :-)
[10:52] <Lahti> we like them as hunting treasures :)

[12:46] <Lahti> my station makes unnecessary work when sondehub page tracking is messed up
[12:47] <PE2BZ> How do you call the -3 dB points of an Yagi in English ? Openingshoek would translate to openinscorner but that sounds strange...
[12:48] <PE2BZ> I am going for beam width :-)
[12:53] <daveake> The areas of high gain are called lobes
[12:54] <bertrik> PE2BZ: aperture?
[12:54] <daveake> Beam width works
[12:56] <PE2BZ> thanks both !

[12:57] <PE2BZ> Anyone experience with panels ? In this case, L-band (inmarsat 1500 - 1650 MHz) 52 x 52 cm what would you expect as beam width ?
[12:57] <PE2BZ> because I have to decide on step size for the az- el setup

[13:01] <SpeedEvil> Airy disk radius is ~ 1.22*wavelength/diameter
[13:01] bing (5cec610d@gateway/web/freenode/ip.92.236.97.13) left irc: Ping timeout: 256 seconds
[13:02] <SpeedEvil> So, 1500MHz is a wavelength of 1/5thm. so the beam will be a bit larger than 2/5ths radians, or about 25 degrees
[13:03] <SpeedEvil> 2.5 degrees would probably be a sane minimum
[13:03] <PE2BZ> thank you !
[13:05] <PE2BZ> 15:42 LT a Noaa-19 pass straight over my head. Curious to see if it appears on the Airspy...
[13:09] <bertrik> at hackerspace revspace we got a few good pictures of the noaa satellites using an rtlsdr and a wideband antenna (discone)
[13:24] <michal_f> My first noaa reception with airspy was on diamond x50 :O
[13:24] <michal_f> noisy, but anyway
[13:25] <PE2BZ> Mine on an x-30 in the backyard of my parents in law. 1200 m away from other houses. only at 7 m above the ground but no noise at all ;-)
[13:25] <PE2BZ> Now aiming at the 1698 MHz signal :-)
