[12:02] <Darkside> ok
[12:03] <Darkside> aroudn here we're going the other way, and starting to move *down* in frequency :P
[12:03] <chris_99> is ~800MHz effected by cloud at all? out of interest

[12:05] <chris_99> cool :)
[12:05] <chris_99> the reason i was slightly wondering, is i believe some microwave ovens
[12:05] <chris_99> use 1GHz
[12:06] <chris_99> actually 915MHz apparently
[12:07] <russss> yeah, it's a myth that microwaves all use 2.4GHz because water has the highest absorption there

[12:10] <chris_99> ah cheers
[12:18] <bertrik> russss: that thing about the water absorption peak being at 2.4 ghz is very stubborn, I hear it a lot

[12:52] <Darkside> i havent had a go at it yet... i would like to run it through some error rate vs SNR tests, but i need a way to get audio into it to do that..
[12:52] <Darkside> plus time
[12:52] <Darkside> PE2BZ: am interested in your experiences with flying RS41 pcbs, as i've had a few issues
[12:53] nickalamos (~x@host86-145-62-192.range86-145.btcentralplus.com) joined #highaltitude.
[12:53] <PE2BZ> I had a misunderstanding it seems..... I assumed (I know....) having an index.html would mean I can point my browser to the Samba share but that does not work. Opening the folder in Explorer and starting the index.html opens it as file and now I cam connect to the SDR part of the decoder :-)
[12:55] <PE2BZ> Darkside bare PCB wrapped with bubble foil, no problem. Using 1 CR123 Lithium battery works for 7 - 8 hours with no problems
[12:55] <Darkside> very weird
[12:55] <Darkside> i've had the radio fail on multiple flights
[12:55] <Darkside> what transmit power were you running?
[12:57] <PE2BZ> either 8 or 12 mW (users did not notice)
[12:58] nickalamos (~x@host86-145-62-192.range86-145.btcentralplus.com) left irc: Ping timeout: 272 seconds
[12:58] <Darkside> huh
[12:58] <Darkside> so i've been running at 25mw, and have had the PLL lose lock on multiple flights
[12:58] <Darkside> including a flight with a RS41 flying 'stock'
[13:01] <PE2BZ> We never noticed anything like that. The only ¨problem¨ I notice is when you power the RS41 directly (so without the power button) and you bounce when soldering the batterij to the V+ connection on the PCB it will never get a GPS lock. So now I use a small slide switch to power on the RS41 when I don´t use the on board switch
[13:01] <Darkside> sigh
[13:01] <Darkside> i think you use some unicode characterin the line above
[13:02] <Darkside> and its messed up my IRC window
[13:03] <PE2BZ> clear
[13:03] <PE2BZ> does that help ?
[13:03] <Darkside> well its cleared now
[13:03] <Darkside> but now i cant see waht you typed :P
[13:03] <Darkside> byt yes, i've had PLL loss-of-lock issues on multple flights
[13:04] <Darkside> am doing a test flight next weekend with a few payloads running in different configurations
[13:04] <PE2BZ> We never noticed anything like that. The only // problem // we noticed is when you power the RS41 directly (so without the power button) and you bounce when soldering the batterij to the V+ connection on the PCB it will never get a GPS lock.

[13:04] <Darkside> isue seems to be when the radio chip gets down around -15 degrees or so
[13:04] <Darkside> so i just shor tthe power button
[13:04] <Darkside> short*
[13:04] <PE2BZ> Do you have long pauses between transmisisons ?
[13:05] <Darkside> nope, transmitting continuously
[13:05] <PE2BZ> I don t recall my TX chip ever getting below zero degrees
[13:05] <Darkside> so the temp measuring code in the RS41HUP upstream repository appears to be broken
[13:06] <Darkside> as in, i went through the chip datasheet and it doesnt quite make sense
[13:06] <Darkside> and the values it produces are not anywhere near reality (admittedly with a thermocouple on the top of the chip, which will add some thermal delay, but its a reasonable estimate)
[13:08] <Darkside> oh, and im not sure the original RS41HUP Code was even converting the values from the ADC value to temperature correctly, i think it hits an overflow..
[13:09] <Darkside> its fixed in my repo.. https://github.com/darksidelemm/RS41HUP/blob/master/radio.c#L46
[13:11] sumie-dh (~sumie-dh@91.146.121.5) joined #highaltitude.
[13:11] <PE2BZ> Maybe I use your code for a next flight. I aboandoned the OM3BC code for giving GPS failures on an RS41. That never happened on the rtty_master code
[13:12] <Darkside> yeah well im hoping theres nothing in my code that makes the radio break!
[13:12] <Darkside> its very weird
[13:12] <Darkside> also i mainly use my code in 4FSK mode, not RTTY mode...
[13:12] <Darkside> which is the kind of point on this payload, to ditch RTTY
[13:13] <PE2BZ> Which is what I abandoned too (sorry) because average age of listeners over here is 65 + and they are trying to decode RTTY with a Baofeng FM radio and LoRa with DL-FLDIGI
[13:14] <Darkside> its ok, they'll all die soon
[13:14] <Darkside> >_>
[13:14] <PE2BZ> lol
[13:14] <PE2BZ> Bad habits survive you know....
[13:14] <Darkside> we've managed to get a lot of listeners around here using 4FSK
[13:14] <Darkside> easier now i just have a binary distribution for iwndows
[13:15] <Darkside> they install freedv, and just run the horusbinary.exe file
[13:15] <Darkside> would be better to have it all integrated into one application, but... time
[13:16] <PE2BZ> I sell programmed Maduino board with LoRa 433 module to the old man over here so they can receive LoRa from our (camera) flights. I buy for 15 US Dollar and sell for 22 Dollar including shipping. That was the easiers way to obtain more LoRa viewers
[13:16] <Darkside> yeah you'd have no hope getting people running wenet then
[13:17] <PE2BZ> Do you have a fulltime job ?
[13:17] <Darkside> yes
[13:17] <Darkside> senior HW engineer...
[13:17] <PE2BZ> You need my job with your brains... I work (average) 23 hours a week
[13:18] <Darkside> oh that'd be nice
[13:18] <PE2BZ> After that I do shopping, cooking, cleaning, yell at the children to do their homework and a lot of hobbies
[13:18] <Darkside> anyway, i'd be interested to see how you go flying my code on one of your flights
[13:19] <PE2BZ> Bare PCB with red foil ?
[13:19] <Darkside> whatever tbh
[13:19] <Darkside> im interested in the temperature reading
[13:19] OZ7EMA (~emanuel_@bo-18-155-254.service.infuturo.it) left irc: Ping timeout: 272 seconds
[13:19] <Darkside> its been very annoying that i've had these issues
[13:19] <PE2BZ> I planned to fly tomorrow, to the UK but the wind is turning to a seal landing
[13:19] <PE2BZ> -l
[13:20] <PE2BZ> sea landing :-)
[13:20] <Darkside> have you seen the various twitter posts on the issues?
[13:21] <Darkside> https://twitter.com/darksidelemm/status/1059410509361893376
[13:21] <Darkside> thats what happens when the PLL goes out of lock
[13:21] <Darkside> bandwidth spreads out, and it starts to drift up as temperature drops
[13:22] sumie-dh (~sumie-dh@91.146.121.5) left irc: Read error: No route to host
[13:23] <Darkside> this kind of failure has been fairly repeatable too... which is whats so odd about it
[13:23] sumie-dh (~sumie-dh@91.146.121.5) joined #highaltitude.
[13:23] <Darkside> makes me wonder if theres any other differences between flights around here and where you are
[13:23] <PE2BZ> I did read the top message ;-)
[13:23] <Darkside> are upper altitude temperatures that different? (we see about -60 degrees C between 12km and 20km alt, where it has failed)
[13:24] <PE2BZ> I think there is no difference over here. On the radiosondes / weathersondes I quite often notice -50 to -66 degrees C
[13:25] <Darkside> yeah, so again, this is whats weird
[13:25] <Darkside> we had a failure on our last flight on descent - only for a short period of time mind you, but we had the failure with a RS41 flying in stock foam+plastic configuration
[13:26] <Darkside> so i'm trying that again next weekend, but at 50mW, and also trying an RS41 at 25mw in a custom foam enclosure, with hopefully better insulation
[13:26] <russss> perhaps it happens infrequently enough that they don't care about it
[13:26] <russss> weird though
[13:26] <PE2BZ> My last freezer test (without GPS lock) was to test the capacity of the CR-123 battery which was wraped in foil, reported +12 degrees as lowest radiochip temperature, with 8 mW tx and lasted more as 9 hours
[13:28] <PE2BZ> I have seen this behaviour on numerous Graw DFM sondes, sometimes on other brand sondes (an unknown type which behaves like this when battery goes low) but I never noticed this on an RS41 as weathersonde. And I have decoded more as 200 so far I think...
[13:28] <russss> if it only gets cold enough to happen on descent then met agencies probably don't care, I assume they're mostly interested in the data on the ascent and they're not going to recover them.
[13:28] <Darkside> PE2BZ: try that again with my firmware...
[13:28] <russss> so I guess it's just a consequence of cost-optimisation
[13:28] <Darkside> would be interested to see if the temp reads differently
[13:29] <Darkside> i modified the code to match how the datasheet says to read temperature, and i also modified how it converts the ADC Value to a int8_t, so as to not overflow
[13:30] <PE2BZ> Did you ever consider to remove / adjust parts on the output of the radiochip ? We usually cut the wire to 1/4 wave measured from the PCB track on the output pin of the radiochip.
[13:30] <Darkside> havent modified any of them yet
[13:30] <Darkside> not really sure it meant to be a 1/4 wave
[13:30] <Darkside> need to know the values of the components in that matching network near the antenna to be sure whats going on
[13:31] <PE2BZ> So with 50 mW and an out of band antenna it could be bad swr problem ?
[13:33] <Darkside> causing PLL loss of lock at low temperatures? doubt it
[13:33] <Darkside> hell, high SWR will cause the chip to dissipate more heat
[13:33] <Darkside> but it wouldnt be much more heat
[13:33] <Darkside> anyway, all the previous flights have run at 25mw
[13:33] <PE2BZ> so I´ll go for 25 mW too ?
[13:34] <Darkside> may as well
[13:37] <PE2BZ> Where did you put my ST-link ....

[13:53] <Darkside> i wouldn't have ever made it use N/S or E/W in the latlong fields
[13:53] <Darkside> well according tothe code, the 40 is apparently the Si4032 on-chip temperature
[13:54] <PE2BZ> let´s see....
[13:54] <Darkside> which isn't entirely unreasonable
[13:55] <Darkside> but yeah, obviously i need to go have a closer look at the RTTY Code, as perhaps someone might want to use it
[13:55] <Darkside> i've just never bothered, since my point in using these payloads was to get away from using RTTY
[13:57] <PE2BZ> WARNING habitat.parser_daemon MainThread: Could not save doc 8f09d8f8aaa54270baf77f700930c58b60ed66d82e99d3b5c68bec83beab996a, unauthorized: {"error":"forbidden","reason":"Validation errors: u'E4.1986' is not of type u'number', u'N51.9916' is not of type u'number'"}
[13:58] <Darkside> yes, which is my point
[13:58] <Darkside> it shouldnt be using E/W and N/S, as that's stupid
[13:59] <Darkside> so clearly i'll have to fix that
[14:00] <PE2BZ> Yes please, I cannot have this approved with nofix ;-)
[14:04] <Darkside> do a git pull
[14:04] <Darkside> and rebuild...

[14:05] <Darkside> that looks better...
[14:06] <PE2BZ> Sigh... This is windows :-)
[14:06] <PE2BZ> Just downloading the ZIP
[14:06] <Darkside> you're building using CoIDE?

[14:08] <Darkside> urgh, ok its almost 1AM, in eed to go to bed
[14:09] <PE2BZ> Have a good night. I´ll try to get into the freezer tonight

[14:18] <Darkside> there we go
[14:18] <PE2BZ> thanks for the fast update :-)
[14:18] <PE2BZ> Now get some sleep....
[14:18] <Darkside> hopefully i havent introduced any other bugs
[14:18] <PE2BZ> I have spray for that....
[14:19] <Darkside> im really not 100% sure about that temp sensor reading... but its really hard to calibrate the damn thing without access to where the chip is
[14:19] <Darkside> i mean, to where the sensor is
[14:19] <Darkside> and the sensor is on the silicon die... and we are separated from that by a chunk of ceramic
[14:19] <Darkside> (or plastic, whatever it is)
[14:20] <PE2BZ> I´ll grab my laser thermometer
[14:21] <Darkside> dont forget that averages over an area
[14:21] <Darkside> i tested by taping a thermocouple sensor to the chip
[14:21] <Darkside> was seeing maybe 2-3 degrees difference between thermocouple reading and the chip reading when at subzero temperatures
[14:22] <SpacenearUS> New position from 03KK6UUQ-2 after 0316 hours silence - 12https://tracker.habhub.org/#!qm=All&q=KK6UUQ-2
[14:25] <Darkside> anyway, at 'room temperature', i woudl definitely expect to see the on-die temp higher than ambient.

[14:55] <PE2BZ> Any info on the rtty settings ? I see a signal on 869.780 but I cannot get the shift right

[15:04] <g8fjg> Hi Ben 869.812 I only see lora M4 but telem only
[15:04] <buzz53> SSC07 RTTY should be 600Hz but TBH we aren't monitoring it. Will take a look now
[15:07] <g8fjg> happen to be in shack...good tropo for next few days N and NE for me
[15:11] <PE2BZ> I would guess it´s 425 shift but for 300 bd I need at least 600 shift to keep mark and space away from each other

[15:15] <buzz53> Looks like JOAL RTTY is only 400Hz, I'm sure I configured for 600, had noticed that before, will need to check.
[15:15] <SpacenearUS> New vehicle on the map: 03KD7MS-4 - 12https://tracker.habhub.org/#!qm=All&q=KD7MS-4
[15:16] <buzz53> Also JOAL seems to have stopped taking images for somr reason. This is the first time we have put the camera outside.
[15:17] <buzz53> This was to avoid the big "hole" that we thought caused the very low temps on descent. But I believe many people put the camera outside normally.
[15:18] <craag> Yes having the rpi camera outside is not normally a problem, but keeping the cable securely in at each end can be problematic.
[15:18] <PE2BZ> I usually put camera inside and lens outside (with the M12 camera´s) or camera PCB outside with the small camera[
[15:26] <g8fjg> got an rtty decode 869.775 ,, big signal ,, but drifts!!
[15:28] <buzz53> We hadn't planned to retrieve this one as we hadn't expected to learn anything from doing so. So we won't know whether the camera came undone
[15:28] <Bozzy> Where are you guys getting your frequencies from?
[15:29] <g8fjg> not sure what you mean Bozzy
[15:30] <Bozzy> What frequency is joel transmitting on?
[15:31] <g8fjg> rtty 869.775 and Lora 869.808 mode 4 for my kit
[15:32] <Bozzy> Thanks, what I mean is, how would I find these frequencies in future?
[15:33] <g8fjg> some times here https://groups.google.com/forum/#!forum/ukhas
[15:34] <g8fjg> sometimes here https://tracker.habhub.org/#!mt=roadmap&mz=7&qm=1_hour&f=JOAL10&q=!RS_*;
[15:34] <PE2BZ> And sometimes you have to ask, tune, wait, search, sigh.....
[15:34] <g8fjg> yep
[15:35] <PE2BZ> Use an SDR as receiver with 434 - 434.800 MHz and see if you find something suspicious
[15:35] <PE2BZ> One Bad CRC :-)
[15:36] <g8fjg> thats what I did just now but on 869 ---870
[15:37] <Bozzy> Confused with the 2 different bands, does a balloon transmit on hoth bands?
[15:38] <PE2BZ> Usually one balloon on one band, but sometimes 2 different frequencies.
[15:38] <SpacenearUS> New vehicle on the map: 03KD7MS-2 - 12https://tracker.habhub.org/#!qm=All&q=KD7MS-2
[15:39] <PE2BZ> More confusing sometimes multiple trackers, like PITS board on 869 MHz for the images and rtty on 434 MHz band
[15:39] <g8fjg> and usually just the 434 434.8
[15:39] <Bozzy> So Joel not transmitting around 434?
[15:40] <PE2BZ> No, 869 MHz band only
[15:40] <Bozzy> Ok, understand now
[15:40] <Bozzy> Thanks
[15:40] <g8fjg> dont think so. I couldn't see any signals so went to 869
[15:41] <PE2BZ> When I fly SSDV I use 432.700 for the SSDV LoRa because it´s 250 kHz bandwidth and I use 434.387 for the RTTY to keep FLDIGI from trying to tune to the LoRa signals
[15:41] <g8fjg> afk
[15:41] <PE2BZ> Let´s quote a bit
[15:41] <PE2BZ> <buzz53> Usual short notice I'm afraid but we hope to launch JOAL10 about 14:00UTC from near Ipswich
[15:41] <PE2BZ> <buzz53> LoRa mode 4 with SSDV on 869.800MHZ, occasional RTTY 300,n,8,2 on 869.775MHz
[15:41] <PE2BZ> <buzz53> We will be uplinking SSDV packet resend requests for the first time
[15:41] <PE2BZ> <craag> Any 434?
[15:41] <PE2BZ> <buzz53> Nope! We are gasping into the 21st century here!
[15:44] <PE2BZ> Bozzy there is an announcement for a 434 MHz rtty flight from Northern Ireland for tomorrow early morning.
[15:45] <PE2BZ> That announcement is on one of the places Ron G8FJG mentioned :-)
[15:45] <Bozzy> Thanks, will keep an eye on it, just seems no easy way or list to find all flights and frequencies
[15:46] <PE2BZ> No, indeed, no easy way....
[15:47] <craag> For well-organised teams they'll tend to be on the mailing list, but in the orderly chaos that is preparation before a launch, the announcement email is one of the most common things to be missed out.
