[07:57] <M0RJX> I think I have found the problem with the lora-gw not sending packets to habhub properly
[07:58] <M0RJX> Its to do with threading and using the curl_easy_init(); function in the thread.
[07:58] <fsphil> couchdb is a bit naff?
[07:58] <M0RJX> If you did not already call curl_global_init, curl_easy_init does it automatically. This may be lethal in multi-threaded cases, since curl_global_init is not thread-safe, and it may result in resource problems because there is no corresponding cleanup.
[07:59] <AndyEsser> fsphil: it's fine
[08:01] <M0RJX> The basic rule for constructing a program that uses libcurl is this: Call curl_global_init, with a CURL_GLOBAL_ALL argument, immediately after the program starts, while it is still only one thread and before it uses libcurl at all. Call curl_global_cleanup immediately before the program exits, when the program is again only one thread and after its last use of libcurl.

[08:02] <M0RJX> I'm no expert on threads but I'm pretty sure we're not doing this in the code.
[08:02] <fsphil> M0RJX: not that you mention it, I see several calls to curl_global_init() in the code. there should only be one in main()
[08:02] <fsphil> now that*
[08:03] <M0RJX> fsphil, I dont thinks so I sent 10000 packets of data spaced by 10ms and everyone was dealt with by chouch just fine
[08:03] <M0RJX> chouchDB
[08:04] <M0RJX> humm CouchDB !!!
[08:04] <fsphil> yeah that one :)
[08:05] <M0RJX> When I looked at the code it should log failures to upload and that wasn't happening. So then I wondered if the thread was a problem. Buy the pi handle threads well so I looked at curl and threading and I think this is the problem
[08:05] <M0RJX> Buy = but
[08:06] <M0RJX> next is to try to do the init before the threads are created :-)
[08:07] <mfa298> from memory I think the threads in lora-gw were added fairly recently to cope with the faster packet rate from the balloons.
[08:07] <M0RJX> That explains the code too. It seemed to have replication in there
[08:07] <mfa298> could be interesting to know if the issue existed before that change
[08:07] <M0RJX> A thread and non thread versions
[08:08] <M0RJX> Does anyone rememeber not getting packets uploaded to habhub before then
[08:09] <M0RJX> I uploaded the rest of my packets for NAILBRUSH last night from the lora-gw logfile and every one was accepted with 10ms between packets but no threads.
[08:10] <mfa298> some people did have issues uploading before, but that was more that the http request took longer to submit than it took for the next packet to arrive
[08:11] <mfa298> although I wonder if that was also masking this issue
[08:11] <fsphil> the other threads calling curl_global_init() could possibly be killing other active requests
[08:11] <M0RJX> Yep in a bad way as they are not reported
[08:11] <fsphil> I'd increase the curl timeout too, 5 seconds is too quick
[08:12] <M0RJX> The code is there to catch errors but its not been executed
[08:12] <AndyEsser> lol
[08:12] <AndyEsser> "We have too much process"
[08:12] <AndyEsser> "Just throw some threads at it"

[08:13] <M0RJX> We never get time out errors. I'm going to create a random backoff timer that will try a few times to post the data before failing too
[08:13] <fsphil> threads everything solve
[08:13] <AndyEsser> :)
[08:13] <M0RJX> very good fsphil
[08:13] <mfa298> at least it's C so it's real threads. ruby (and I think python) do their own locking internally so threads don't always speed things up.
[08:14] <AndyEsser> mfa298: threads will never "just speed things up", you know this
[08:14] <AndyEsser> tsk tsk
[08:16] <mfa298> well for ruby (and I think python) there more for convenience (I want to do these thigns in parallel) rather than making use of all the hardware.
[08:17] <mfa298> which is annoying when you want to use them to make use of the hardware
[08:17] Action: AndyEsser sits smugly in his C/C++ world
[08:17] <fsphil> handy for waiting on things that block
[08:17] <AndyEsser> then remembers he's currently paid to write Go and weeps
[08:18] <daey> you are writing a Go engine?
[08:18] <fsphil> that bad huh?
[08:19] <mfa298> the times that I write ruby code I feel that I don't add features any faster than using C/C++ but my lines of code/hour drops substantually.
[08:19] <M0RJX> So should I hack the code to post a load of sentances and see whats happing or do I make the curl stuff global and call curl init at the beginning ?
[08:19] <mfa298> probably as I have to read the manual more for ruby.
[08:20] <AndyEsser> fsphil: I hate it
[08:20] <daey> you should be significantly faster o0
[08:20] <fsphil> M0RJX: as a first step anyway I'd get rid of all the curl_global_init()'s, and just have the one at the top of main()
[08:21] <M0RJX> !last daveache
[08:21] <M0RJX> RIght I'm on with it
[08:21] <gonzo_> is that what Julie gets?
[08:21] <M0RJX> Hopefully this solves the problems :-)
[08:22] <fsphil> gonzo_: hah
[08:22] <AndyEsser> fsphil: C or C++ this code is?
[08:22] <fsphil> AndyEsser: the gateway is C

[08:28] <PE2BZ> That´s C64 code
[08:28] <AndyEsser> I really need to try and find an old Atari or C64 or something
[08:28] <AndyEsser> I missed out on programming those :(
[08:29] <PE2BZ> With a tape recorder :-)
[08:30] <fsphil> and the loading music
[08:31] <fsphil> I love that there are still people making and selling c64/amiga games
[08:33] <Vaizki> Hnbghhh win10 autorebooted at home it seems
[08:34] <fsphil> for your own protection
[08:34] <Vaizki> it's the only thing that pisses me off about win10 atm
[08:34] <PE2BZ> In my early years (that would be about 35 years ago) we wrote software and build a hardware decoder for the Deutsche Presse Agentur images send at the longwave. The software did run on the Atari ST. The colour images where sent 3 times (C, M Y if I am right) and we even managed to get those 3 combined to a nice colour image. Those where the days :-)
[08:34] <AndyEsser> fsphil: I Was working on a SNES emulator in Javascript the other year
[08:35] <Vaizki> I love the i386 simulator done in JS
[08:35] <fsphil> I thinkered with a 6510 + VIC chip emulator. got the c64 boot screen but didn't go further with it
[08:35] <fsphil> the world has enough c64 emulators already :)

[08:37] <AndyEsser> it'll probably upset me

[08:42] <mfa298> failing that I've got an unused xp pro cd+license
[08:42] Action: mfa298 ponders whether he should take it to a ham rally and auction it off. Probably lots of interested buyers there!
[08:44] Action: gonzo_ hides face
[08:44] <fsphil> I found some Win3.11 floppies a few days ago...

[08:52] <arjunnaha> How well would I be able to track Steve's flights with an X50 in a new build attic, from the Reading area?
[08:54] <AndyEsser> arjunnaha: should be doable
[08:54] <AndyEsser> might have to wait until it reaches a decent altitude
[08:55] <AndyEsser> I've tracked Cambridge flights from Chester with an X50 on the back of my house
[08:55] <arjunnaha> I'm excited lol, tried but never successful in trying to track flights.
[08:56] <AndyEsser> the roof gets in the way for a bit, but at about 10km altitude I start to pick them up
[08:56] <AndyEsser> and from Dave's launches I get them from about 5km but noisey
[08:57] <arjunnaha> I'll have to see in a few hours!
[08:57] <AndyEsser> good luck :)
[08:57] <AndyEsser> is the antenna already installed?
[08:58] <arjunnaha> Not yet, will do in 10 minutes
[08:58] <AndyEsser> make sure you test trying to receive something first, whilst not designed for it - should be able to pick up some FM radio stations
[08:58] <AndyEsser> or a 434 repeater if there's one not too far away
[08:59] <arjunnaha> I need to look for some 434 repeaters in my area

[09:03] <mfa298> arjunnaha: https://www.ukrepeater.net/ has the list of all repeaters and details
[09:03] <mfa298> although you might have to wait ~15 mins for a short ident
[09:03] <arjunnaha> Ah great, thanks
[09:03] <AndyEsser> arjunnaha: just bear in mind that the X50 is good for 137~
[09:03] <AndyEsser> not for 88-100
[09:03] <AndyEsser> so whilst it should work, you might not get the strongest signals
[09:04] <mfa298> aprs can be quite a good test, especially if you've got something setup to decode it (although it takes some reading of the packets to see who you received from directly)
[09:04] <Vaizki> you can get broadcast fm with almost anything...
[09:04] <arjunnaha> When it was mounted at school, I could pick up London stations pretty well
[09:04] <AndyEsser> Vaizki: it was merely an addendum ;)
[09:04] <mfa298> depending on gardent

[09:05] <mfa298> depending on garden putting the x50 outside on some poles might be a bit better than in the loft
[09:05] <mfa298> although if loft works it can be a bit more permanent
[09:06] <AndyEsser> yea, my X50 is on a 3m length of 40x40mm wood, cable tied to a pipe from the boiler on the side of the house
[09:06] <AndyEsser> then a 2m pvc pipe
[09:06] <AndyEsser> and mounted on that
[09:06] <AndyEsser> :)
[09:06] <arjunnaha> Only pole I have a 5m flexible one, I have tried to use the X50 with it before, but it's really unsteady
[09:06] <Vaizki> my x50 is at the end of a telescopic tree cutting tool pole right now :)

[09:08] <AndyEsser> have the x50 on one part
[09:08] <AndyEsser> QFH on another
[09:08] <AndyEsser> and a 434 and 868 yagi on the other pointing SE

[09:10] <mfa298> just don't follow the guidance from the site posted last time this was discussed
[09:10] <AndyEsser> before doing that though, should check with my landlord :(
[09:12] <arjunnaha> mfa298: What was that guidance saying lol
[09:12] <mfa298> arjunnaha: was a site showing many bodged tv antenna installs
[09:12] <PE2BZ> AndyEsser before checking check your insurance. If it covers damage to people and goods for damage from your antenna installation it will be much easier to convince him.
[09:12] <gonzo_> may be worth checking what roof tiles you have, they may be rf tranmsparent-ish

[09:15] <arjunnaha> What's a sub £100 mast suitable for mounting to a wall?
[09:15] <PE2BZ> For damage to others property ? How do they call that in UK ?
[09:15] <gonzo_> AndyEsser, anyone actually.
[09:15] <AndyEsser> PE2BZ: I don't have insurance for damaging someone elses propetty
[09:15] <AndyEsser> property*
[09:15] <AndyEsser> my company has public liability insurance, so as long as I wangle it as a business thing, at least I'm covered if it kills someone...
[09:16] <AndyEsser> up to £10 million
[09:16] <gonzo_> occupiers liability would cover breaking the hosue
[09:16] <gonzo_> 3rd party liability would cover dropping a mast on a passer by
[09:16] <AndyEsser> gonzo_: but that's going to home insurance, not contents insurance
[09:16] <AndyEsser> to be*
[09:17] <PE2BZ> Ok. legal liability insurance over here has a separate part for damage to others (and property) for something that comes of your house
[09:17] <AndyEsser> if it was part of the house falling and damaging/hurting someone
[09:17] <AndyEsser> I would expect that would come until home insurance
[09:17] <gonzo_> if the building gets flooded, that would be the landlords ins. But if you break the house, that would be your ins
[09:17] <AndyEsser> gonzo_: but tenants typically only have contents insurance, ie against theft/fire etc
[09:18] <AndyEsser> anyway
[09:18] <AndyEsser> will have convo with landlord before drilling big holes int he walles ;)
[09:18] <AndyEsser> omg
[09:18] <AndyEsser> typing...
[09:18] <gonzo_> hmmm, your mast, on their house... Expect a big argument from the companies
[09:19] <AndyEsser> The mast and the property count as business - so I'd throw it under one of the... like 5 insurances the company has
[09:19] <AndyEsser> ha
[09:19] <AndyEsser> anyway...
[09:19] <AndyEsser> shall we discuss something happier?
[09:19] <PE2BZ> Sure !
[09:19] <gonzo_> yep, ok
[09:20] <gonzo_> what mode lora is steve's flight today
[09:20] <PE2BZ> 27 degrees and sunny over here
[09:20] <gonzo_> just setting up the pi gateway
[09:20] <PE2BZ> Is Steve carryin lora ?
[09:20] <gonzo_> I'd nee dan inclinometer to see what degs the sun is here
[09:21] <gonzo_> looks like it. A 2ndary payload with lora/rtty
[09:21] <daveake> That's mode 0 gonzo_

[09:30] <M0RJX> hey daveake did you see my post with the problem with the lora-gw?
[09:30] <daveake> the ID thing for ssdv upload?
[09:30] <M0RJX> no curl_global_init is not thread safe
[09:30] <daveake> no didn't see that
[09:31] <M0RJX> nor is curl_global_cleanup
[09:31] <daveake> ok
[09:31] <daveake> Add it to the growing list of requests please :)
[09:31] <M0RJX> So I have moved these calls into main() in gateway.c
[09:31] <daveake> ah right you did it for me? :)
[09:32] <M0RJX> and hopefully we won't lose any more logged packets
[09:32] <M0RJX> :-)
[09:32] <daveake> That curl stuff was a pita
[09:32] <fsphil> open source innit
[09:32] <daveake> indeed
[09:32] <M0RJX> I just need to test a few posts is htere any way to load the buffer or shall I hack the code?
[09:33] <daveake> Next time I'll just do main(){}, stick on github, and wait
[09:33] <daveake> Well if you have a Tx transmitter then just get that to send some packets
[09:33] <M0RJX> I'm also going to add a backout algorithm to deal with 409 errors when habhub is too busy and it wil wait a random number of milli seconds and try to post again three times before giving up
[09:34] <M0RJX> daveake, not that easy as my gateway is in england and i'm in lanzarote :-)
[09:34] <fsphil> you should do the same for ssdv packets too, though it shouldn't have as many problems as habitat
[09:34] <daveake> I see ...
[09:35] <M0RJX> the wonders of putty
[09:35] <daveake> "you" being Rob :-)
[09:35] <M0RJX> Yep :-)
[09:35] <daveake> hey you're on a roll :)
[09:35] <fsphil> hey I'm getting the hang of this :)
[09:35] <M0RJX> Did you see my testing telem
[09:37] <PE2BZ> Is the APRS frequency for UBSEDS18 144.800 ?
[09:37] <M0RJX> daveake, check this test around 0,0 https://tracker.habhub.org/#!mt=roadmap&mz=11&qm=All&mc=-0.06369,0.00663&q=icarusIV
[09:37] <daveake> lol nice
[09:37] <daveake> I did a UFO over London once
[09:38] <daveake> (flying saucer).
[09:38] <daveake> That was back when I started, after having 2 separate meridian issues
[09:38] <M0RJX> Yeah nobody seams to test anymore aparently
[09:39] <fsphil> yeah these off-the-shelf trackers eh :)
[09:39] <edmoore> M0RJX: i don't know if you were around a few years ago when on april fool's day the predictor had all the paths spiraling in to the nearest airport
[09:39] <daveake> hah
[09:39] <M0RJX> I'v created a ubx over uart code which takes a kml file and makes ubx-nav-pvt messages from it
[09:39] <M0RJX> edmoore, I think that was in my down time :-)
[09:40] <edmoore> yeah probs
[09:40] <WillDWork> cool - M0RJX - can you share?
[09:41] <M0RJX> sure it's in the same vain as steves gpsGen and gpsEmulate I've only tested on windows and it's dirty :-)
[09:41] <M0RJX> Yu have to set the com port in the code. It's woring under mingw
[09:44] <M0RJX> kml to ubx should work anywhere
[09:45] <M0RJX> sending the ubx to the payload on windows I hade to write some code which waited for a # to be sent and it would respond with the next ubx message

[10:31] <Geoff-G8DHE> winder if 434.250 is the right frequency ?
[10:31] <Ron_g8fjg> yes but maybe not today ..certain qrgs have permanent transmissions on,,,big signals , best avoided.I dont know how the freqs are loaded, but probably not rocket science.

[13:09] <amell> this balloon is going right over my head. if i was at home i'd get the telescope out...
[13:10] <Geoff-G8DHE> You will have to manually congure X0 as its also LoRa and payload doesn't understand it

[13:29] <PE2BZ> Is it possible to set the frequency tracking in fldigi to a more gentle mode ? Now it hops about 500 Hz down in the middle of a packet.
[13:32] <Geoff-G8DHE> on the dl config page you can set it how you like I do +-20Hz
[13:33] <PE2BZ> On Frequency Tracking I can set minimum and maximum, as it reaches maximum it hops 500 hz down instead of slowly tuning. I can not see a setting where I can adjust the steps ?
[13:34] <Geoff-G8DHE> its from a centre freqency I use a centre of 1500Hz then have it set for 1480 and 1520

[14:59] <fsphil> hah
[15:00] <Ian_> I was just thinking about that, but have to admit that I was very uncertain. You could have got over that with different length on one of the phasing loops, just for asthetics .. . Something else learned
[15:00] <fsphil> I got a strong signal either side of the direction of the payload
[15:00] <dbrooke> they also appear to have 10 elements, not 11
[15:00] <AndyEsser> off by one error
[15:01] <fsphil> ah man
[15:01] <dbrooke> what make are they fsphil ?
[15:01] <fsphil> diamond
[15:02] <gonzo_> yep it becomes a broadside array-ish
[15:02] <Ian_> I guess that small errors in the phasing would give it a squint. Lots of £
[15:02] <fsphil> no idea where I got 11 from
[15:02] <Ian_> 18dBd at best?
[15:02] <gonzo_> on our club antennas I have used clamp cable glands to secure the elements to the feed box. And used red and black ones so we can get the phasing right
[15:02] <fsphil> spec says 13.1 dBi each
[15:03] <gonzo_> (have failed at that a few times!)
[15:03] <gonzo_> probably a real gain then
[15:05] <Ian_> So around 16.2dBi as a very well matched pair, which is around 14dBd. I think that as you approach 12dBd you enter a region of diminishing returns

[15:09] <PE2BZ> arjunnaha within the sample range it can. If you have it in 5 Ms mode and the frequencies are less than 4.8 MHz apart
[15:10] <arjunnaha> How can you do that?
[15:10] <gonzo_> craag, it has to be in the 20dB range
[15:10] <gonzo_> on a 3.7mtr
[15:11] <PE2BZ> arjunnaha which OS / software are you used to ?
[15:11] <mfa298> arjunnaha: that's down to your software, sdr-radio has support for several vfos
[15:11] <arjunnaha> Windows
[15:11] <arjunnaha> I'm using sdr# atm
[15:11] <gonzo_> craag, and it was Julian. G3YGF
[15:11] <mfa298> arjunnaha: you can also do it with most other dongles, just as long as the frequencies your want are all in the sample space
[15:11] <PE2BZ> Then SDR-radio V2 or V3 will be a good choice. Up to 6 (v2) or 30 (V3) vfo´s within the sample rate range
[15:12] <arjunnaha> too late, just gone below my horizon

[18:28] <Upu> hey M0RJX sorry just saw your texts
[18:28] <Upu> 0.3mm :)
[18:32] <M0RJX> Upu, yeah you answered earlier on here :-)
[18:32] <M0RJX> is that 12mills
[18:32] <M0RJX> or 0.12 mills
[18:33] <Upu> metric or busy baby
[18:34] <PE2BZ> condx on 70 are going up. UBSEDS18 449 km at -0.3 elevation on the V-2000 diamond colineair
[18:35] <Upu> bust
[18:35] <Upu> tbh no idea what a mil is
[18:35] <Upu> is it 1000th of an inch ?
[18:36] <PE2BZ> mil is. but mills is common millimeters (says wikipedia)
[18:37] <M0RJX> Humm any how I think they just look big in the picture whan I scale it to size they look tiny :-)
[18:39] <Upu> you should be able to get away with 0.3mm ones
[18:39] <M0RJX> Upu, I fixed the lora-gw today moving the none thread safe calls into the main program
[18:39] <Upu> is that the fix for uploaders or is that different ?
[18:39] <M0RJX> fix is for uploaders
[18:39] <Upu> ok
[18:39] <M0RJX> I've pushed this to daveake
[18:39] <Upu> sure daveake will implement that he's doing some things to it anyway
[18:39] <Upu> on the fly mode changes etc
[18:40] <M0RJX> I uploaded a few hundered sentances today for nailbrush
[18:41] <M0RJX> Not one failed to be added
[18:44] <Geoff-G8DHE-Lap> But desn't the problem only appear when there is more than one station uploading ?
[18:44] RocketBoy (~steverand@0541ee85.skybroadband.com) joined #highaltitude.
[18:46] <M0RJX> Geoff-G8DHE-Lap, when I loked at the code last night and this morning it looks like the problem was with curl_global functions been executed in the threads which is a big nono according to curls docs
[18:46] <Geoff-G8DHE-Lap> SO not the 409 response of locked records on the CouchDB ?
[18:48] <M0RJX> Geoff-G8DHE-Lap, these are captued and reported by the lora-gw if they occure
[18:48] <M0RJX> The basic rule for constructing a program that uses libcurl is this: Call curl_global_init, with a CURL_GLOBAL_ALL argument, immediately after the program starts, while it is still only one thread and before it uses libcurl at all. Call curl_global_cleanup immediately before the program exits, when the program is again only one thread and after its last use of libcurl.
[18:49] <M0RJX> if you grep the source for curl_global you wil see it's called all over the place
[18:49] <M0RJX> well in four places
[18:49] <M0RJX> all after threads have started
[18:50] <PE2BZ> M0RJX if I understand right the LoRa gateway should mention if uploads failed because of the 409 error ? Indeed I have seen no errors on my screen.
[18:50] <M0RJX> I have pushed a fix to daveake from my fork
[18:50] <M0RJX> PE2BZ, correct
[18:51] <M0RJX> Thats what lead me to think that the problem was else where and I looked into curl and threads when I read the bit about parts which arn't thread safe
[18:51] <Geoff-G8DHE-Lap> It only sends a fail message if it times out rather than a bad response, but I haven't dug into the code at all deeply.
[18:51] <PE2BZ> I have received over 600 packages and have seen no error like 409 at all. So I go for the Curl fix ;-)
[18:52] <PE2BZ> Only 37 got registered so if it was because of error 409 I certainly would have noticed.
[18:52] <Geoff-G8DHE-Lap> But it doesn't report failed responses, only timed out requests ..
[18:53] <M0RJX> Geoff-G8DHE-Lap, after culling in the data the code does the following
[18:53] <M0RJX> // Perform the request, res will get the return code
[18:53] <M0RJX> res = curl_easy_perform(curl);
[18:53] <M0RJX> // Check for errors
[18:53] <M0RJX> if (res == CURLE_OK)
[18:53] <M0RJX> {
[18:53] <M0RJX> LogMessage("OK\n");
[18:53] <M0RJX> }
[18:53] <M0RJX> else
[18:53] <M0RJX> {
[18:53] <M0RJX> LogMessage("curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
[18:53] <M0RJX> }
[18:53] <M0RJX> Now I'm not sure if a 409 is a curl ok response
[18:55] <PE2BZ> I am leaving for the night. Cu tomorrow !
[18:56] <M0RJX> CURLE_HTTP_RETURNED_ERROR (22)
[18:56] <M0RJX> This is returned if CURLOPT_FAILONERROR is set TRUE and the HTTP server returns an error code that is >= 400.
[18:56] <PE2BZ> UBSEDS18 is almost going to sleep...
[18:56] <M0RJX> PE2BZ, bye
[18:57] <Geoff-G8DHE-Lap> Ok, well wait for dave to merge it.

[19:57] <M0RJX> Any lora flights planned?
[20:09] <michal_f> has any body build dl-fldigi for odroid or raspi ?
[20:09] <Upu> yes
[20:09] <Upu> not me ]
[20:09] <Upu> :]
[20:12] <michal_f> are there any binaries to download ? :)
[20:12] <michal_f> (and does raspi and odroid binaries are cthe same / compatible ? )
[20:14] <Upu> no idea to both
[20:14] <Upu> I tried once and decided to just use Windows
[20:14] <Upu> as life is too short
[20:14] <michal_f> haha :) yeah
[20:14] <michal_f> you convinced me to get me a beer ...
[20:15] <michal_f> btw upu, I just plugged in NTX2b you fixed for me and it switched to lower freq. so it seems to work :)

[21:02] <michal_f> dbrooke, what type of radio you have with your odroid ? Some SDR ?
[21:03] <dbrooke> Using a USB audio device and an IC-R7000 (with USB serial for hamlib control)
[21:04] <michal_f> ok
[21:07] <dbrooke> I have a GPIO controlled relay for the rig power and x11vnc server so it's remotely accessible
[21:08] <mfa298> michal_f: someone at the Pi foundation has been trying to run dl-fldigi + sdr on a Pi3 but i think there are some issues still
[21:08] <mfa298> dl-fldigi should be fairly easy to compile though, similar to any other linux machine
[21:09] <michal_f> thats what I try to do. rtty decode on odroid (has more power that PI3)
[21:09] <michal_f> I successfully decoded USB signal with csdr. now is rtty part
[21:09] <michal_f> I'm moving really slow, but forward :)
[21:10] <mfa298> I think csdr + dl-fldigi was the setup the person at Pi Towers was doing but having issues with.
[21:10] <mfa298> I'm guessing the issue is piping the audio around as that's been an issue on most linuxes
