[04:43] Good to be back :-) [04:43] so yeah, that looks like one of the older imets? [04:43] yeah very old [04:43] the imet-1 i have here has a '6 kHz bandwidth' sticker on the side [04:44] Ok I remember using those at loon, these are the wide bandwidth originals [04:45] hrm [04:45] yeah i dont know much about those sorry... i never added support for them in auto_rx because i thought they were obsolete [04:46] looks like 50KHz. it is AFSK, I'm routing the output via an audio channel to SkySonde. [04:47] they were the only ones with an XDATA serial input until recently, which is why I'm still using them [04:48] oh damn, if its AFSK then putting a notch in th emiddle will likely break FM demodulation [04:49] if it was true FSK then you might have gotten away with it [04:49] Do you support XDATA? [04:50] Hmm how about just reducing the amplitude of the middle? [04:51] i dont decode XDATA on the imets, no [04:51] only on the vaisala sondes [04:54] I'll have to look into your program more, I've sort of avoided all linux solutions, it's usually so infrequent that I do the sondes that I need a quick GUI download for windows or mac that gives immediate gui feedback of what's happening [04:54] New position from 03BSS31 after 0315 hours silence - 12https://tracker.habhub.org/#!qm=All&q=BSS31 [04:54] But I do have a raspberry pi that I've used an SDR on before [04:55] yeah skysonde is probably better for decoding the research sonde stuff [04:55] auto_rx is reallt only about positional information, not about the other telemetry [04:57] Ahh gotcha, that's great to know, I've been curious to listen for the local met soundings. Does auto_rx support the gigahertz band? [04:57] The local office switched to them a few years ago [04:57] urgh [04:57] yeah it kind of does [04:58] you need to specify the channels, the automatic peak detection stuff doesn't work on the 1680 MHz band well [04:58] it'll decode the LMS6 1680 MHZ sondes. there's quite a few stations tracking them now [04:59] interesting, what does peak detection do? is that how it picks up any sonde automatically in the band? [05:01] does your program decode the 50khz imet-1? [05:03] yes, and no [05:03] (yes - peak detection finds sonde signals and attempt to decode their type before starting a decoder) [05:03] (no - i don't support the 50 kHz iMet-1) [05:06] gotcha, I do have a pile of new RS-41s which also have the XDATA port, is there any interest in supporting it on that sonde? I'd like to set up an unmanned station on a ridge here so I don't have to worry about my car antenna doing the job [05:06] at the moment the RS41 XDATA output is dumped to the log files auto_Rx produces [05:06] i dont make any attempt to decode it [05:06] but it's in ASCII? [05:06] hex actually [05:07] oh right, that's how I input it to the serial port [05:07] that's ok [05:07] it would be good having someone like yourself check the logged XDATA output is matches what you input! [05:07] because so far we really only have some data from ozone sondes, and we really dont know how valid it is [05:07] I would be happy to! is there an example of the log file format on your github? [05:08] ahhhhh not really lol [05:08] its just CSV [05:08] I actually send using one field in the ozonesonde template, (too lazy to make a custom entry in skysonde) I could stuff values into all the fields and [05:09] timestamp,serial,frame,lat,lon,alt,vel_v,vel_h,heading,temp,humidity,type,freq_mhz,snr,f_error_hz,sats,batt_v,burst_timer,aux_data [05:09] nice! CSV is great [05:09] 2020-08-29T01:03:10.000Z,R2310709,301,-34.72076,138.69286,86.3,-0.1,0.5,53.5,-273.0,-1.0,RS41,400.500,31.4,937,7,3.0,-1,-1 [05:09] perfect! [05:09] aux_data field is -1 if no data, should be hex bytes if there's XDATA coming in [05:10] the RS41 decoded temp values are within 0.5 degrees or so, humidity is a bit iffy at the moment, as the calculations are not done correctly [05:11] doesnt compensate for temperature of the humidity sensor correctly [05:11] yeah I don't have the proper ground calibration box to setup the RS41, so the actual temp/humidity accuracy of each sonde is a tossup here [05:11] oh with the defrost heater on the sensor I guess that would be important [05:11] yep [05:12] i think RH ends up being about within 5-10% of vaisalas values, gets worse as the sonde gets colder [05:12] I'm generally just roughly interested in the humidty vs. temperature for cloud deck detection, so that's probably good enough? [05:12] yeah [05:12] you'll see that for sure [05:12] nice [05:12] That's for correlating the dust sensor readings. [05:13] ooh dust sensor [05:13] so i recently flew a holographic microscope for the University of Adelaide [05:14] 405nm laser, onto a CMOS sensor. they were able to image water droplets and ice particles [05:15] oh wow! that's awesome, I'd love to see those [05:16] This was originally to detect when loon balloons were in ice clouds and accumulating frost [05:16] the original paper is "A low-cost digital holographic imager [05:16] for calibration and validation of cloud [05:16] microphysics remote sensing" [05:16] ugh [05:16] its a few years old, but it describes the technique [05:16] recent work has been making the unit a bit more robust and launching it under a HAB [05:18] yeah looks pretty heavy in this paper, but very cool images! [05:18] oh yeah, its not light even now [05:18] lol [05:19] lots of work to miniaturise it [05:19] well I need to grab lunch, thank you so much for your help and info Mark, good to chat again :-) [05:19] no probs!

I was curious whether anyone has experience using hydrogen rather than helium in a mylar pico balloon. I would think that it would be reasonably safe given the small balloon volume, and would have an advantage of greater lifting capacity/volume. [16:08] No experience myself by there have been a few picoflights using H2 , they should get you about 8% extra alt compared to HE [16:09] I have a pure H2 generator on order from aliexpress, but it will be here to late for test this season [16:11] I'll have to search some more and see if there are any writeups on the hydrogen balloons. Would be interested to learn more about their experiences. [16:12] Il give you some links in a moment [16:12] New vehicle on the map: 03KD0AWK-2 - 12https://tracker.habhub.org/#!qm=All&q=KD0AWK-2 [16:12] New vehicle on the map: 03KD0AWK-4 - 12https://tracker.habhub.org/#!qm=All&q=KD0AWK-4 [16:13] on the left, read http://qrp-labs.com/flights/u4b10.html [16:13] Thanks! [16:13] I've launched one pico balloon before, but it never climbed above 27,000'. I'd like it to be closer to 35-40k to better avoid the weather. Of course hydrogen isn't the only solution, but figured it might be an straightforward performance boost. [16:13] VE3KCL mostly uses H2 on his flights [16:14] yep, get the payload as light as possible and you get near or over 12000m with a cheap 1$ aliexpress foil [16:15] http://yo3ict.uus.ro/ [16:15] flight 3 [16:29] gb73dx (gb73d@host-92-0-93-100.as43234.net) joined #highaltitude.
