[10:33] <fsphil> J123: it might be simpler to create a new payload doc, paste in your string and tell it what each field means.
[10:33] <SA6BSS-Mike|2> is it possible to clean the map from m10rs-11 & Ballon-11 or they will be on the map for the next 2 weeks or so
[10:34] <J123> I'm not sure what each field means, I am new to this and the PITS manual doesn't say. Sorry if it is a stupid question
[10:35] <fsphil> can you paste a string here
[10:35] <Geoff-G8DHE_> Have you read this document http://www.pi-in-the-sky.com/index.php?id=getting-on-the-map
[10:35] <fsphil> oh nice, that page has all the info
[10:37] <J123> Yeh I've read everything I can find. I'm adding a external temperature and a BME280 sensor. Is that a string field
[10:42] <Geoff-G8DHE_> Strings can be any character from the keybaord "abc123", not sure what your sensor generates but it would normally be a an Integer =123 or a floating number like 123.456
[10:46] <J123> Okay that explains some things thank you. How do I know which part of the fields my payload is sending are which sensors

[11:40] <richardeoin> We've been experimenting with using the Better Portable Graphics (BPG) format for ssdv, instead of jpeg http://bellard.org/bpg/
[11:41] <richardeoin> the images are a fair bit better for the same file size, and there's no banding which is nice

[11:42] <adamgreig> interesting
[11:42] <adamgreig> H.265 basically
[11:42] <richardeoin> yup, it uses the x265 encoder
[11:42] <richardeoin> which is quite computationally expensive, about 1 minute on a Pi3 and 5 minutes on a PiZero (-q 33 -m 8)
[11:42] <adamgreig> wow
[11:42] <adamgreig> for a frame?
[11:42] <fsphil> yikes
[11:43] <richardeoin> yes, just one image
[11:43] <adamgreig> cor
[11:43] <richardeoin> indeed
[11:43] <fsphil> is it that much better?
[11:43] <adamgreig> guess the encoders are not well optimised yet, and no hardware
[11:43] <richardeoin> I'm not quite sure what it's doing
[11:43] <adamgreig> also patent encumbered, though not an issue for you i guess
[11:43] <adamgreig> did you look at some of the other new image compression formats?
[11:44] <richardeoin> but yes no hardware optimisation, it doesn't know about SSE or NEON
[11:45] <richardeoin> err we might have looked at others?
[11:45] <fsphil> I played about with webp a bit but it wasn't all much better than jpeg
[11:45] <richardeoin> bristol Adam did some samples with hab images and concuded bpg was the best
[11:45] <adamgreig> bpg really is a lot better
[11:45] <adamgreig> I could definitely believe it

[12:04] <adamgreig> fsphil: thinking a little more about fountain codes, I wonder if they would be well suited
[12:05] <adamgreig> do you think it would be better to have each packet be 10% bigger such that you can handle 10% bit errors during receiving each packet...
[12:05] <adamgreig> but still need to get every packet to decode the whole image
[12:05] <adamgreig> or, transmit the whole image as currently, but then transmit an extra 10% packets at the end, such that so long as you receive 100% of the 110% of packets sent, you can fully decode the image
[12:05] <adamgreig> well, some mix of both I guess obviously
[12:05] <adamgreig> since you already have a RS code on the packets
[12:06] <Darkside> the RS code is kind of useless for rtty tho
[12:06] <adamgreig> but I wonder if it's better to just put more coding on each packet, or to transmit a few "extra" packets at the end, so that you just need to receive the right number in total
[12:06] <Darkside> since you drop bytes

[12:06] <adamgreig> you can RS code erasures too

[12:06] <fsphil> I count the missing bytes
[12:07] <adamgreig> I mean you often get corrupt bytes, more often than missing start/stop bits, I would think
[12:07] <Darkside> better to use a modem that fdoesnt rely on start/stop bits
[12:07] <adamgreig> sure, but this is what we've got
[12:07] <Darkside> well
[12:07] <adamgreig> any given bit is the same prob error
[12:07] <Darkside> there are alternatives
[12:07] <Darkside> just not nicely packages
[12:07] <adamgreig> 20% are start/stop bits, rest will just corrupt the byte
[12:07] <Darkside> niceley packaged*

[12:07] <Darkside> i mean, we've flown 4FSK binary packets just fine
[12:07] <fsphil> it counts the samples between bytes from the rtty modem, and inserts zeros for however many it calculates are missing
[12:07] <adamgreig> reagrdless I think RS works just fine over RS-232
[12:08] <fsphil> works better than I expected
[12:08] <adamgreig> my question is more that if we wanted to make ssdv a bit more reliable, is it better to use a lower rate RS code (so we can handle more bit errors in a packet, but need to receive all packets) or transmit more packets (so we can handle missing a few packets entirely, so long as we receive enough packets in total)
[12:09] <fsphil> never allowing partial image?

[12:10] <adamgreig> you'd still be ok with partial images
[12:10] <adamgreig> you just transmit each packet as currently, then spend a further 10% of the time transmitting parity packets
[12:10] <adamgreig> with the overall effect that if the original was 100 packets, you transmit 110 packets, and the receiver needs any 100 packets to get a full image
[12:11] <adamgreig> but the first 100 packets are same as currently, so you can still decode the image as it comes in, and still get partials even if you end up not getting 100 overall
[12:13] <Darkside> it would be nice if we could package a raw FSK modem into fldigi..
[12:13] <fsphil> spreading it out over the whole image would work quite well
[12:13] <adamgreig> depends on the nature of the errors
[12:13] <Darkside> i.e. give it the preamble bytes and a packet length, and it just looks for that
[12:13] <Darkside> and spits out the received packets
[12:13] <adamgreig> Darkside: yea that would be nice
[12:13] <adamgreig> as usual I like to imagine you'd have a better time making a new app
[12:14] <Darkside> yeah
[12:14] <adamgreig> that just does fsk modem and spits the packets into something
[12:14] <fsphil> agreed
[12:14] <adamgreig> but in practice we always say that
[12:14] <adamgreig> and it's never worked
[12:14] <adamgreig> so just dealing with shitty fldigi modes is probably better lol
[12:14] <Darkside> we have the FSK modem spitting out soft decisions now too
[12:14] <adamgreig> nice
[12:14] <Darkside> so we can now do LDPC and the like
[12:14] <adamgreig> got a soft decision decoder?
[12:14] <Darkside> or whatever
[12:14] <Darkside> yes, the demod will give soft decisions
[12:14] <adamgreig> decoder not demod
[12:15] <adamgreig> i did a cute C one for martlet 2 rocket https://github.com/cuspaceflight/m2-electronics/blob/master/m2r/software/radio_dev/ldpc_decoder.c
[12:15] <adamgreig> encoder is https://github.com/cuspaceflight/m2-electronics/blob/master/m2r/software/radio_dev/ldpc_encoder.c
[12:16] <adamgreig> quite good https://github.com/cuspaceflight/m2-electronics/blob/master/m2r/software/radio_dev/results.png
[12:16] <AndyEsser> someday I'll get around to writing my own demod stuff sometime
[12:16] <adamgreig> oh that's the old one actually
[12:16] <adamgreig> forgot
[12:17] <adamgreig> https://github.com/cuspaceflight/m2-electronics/tree/master/ground/libldpc
[12:17] <adamgreig> is the tidied up C version
[12:17] <adamgreig> whole decoder is 101 lines of C
[12:17] <adamgreig> there's also a rust version :P
[12:18] <Darkside> lol
[12:19] <adamgreig> couldn't get the rust version quite as fast as the C
[12:19] <adamgreig> both were very fast though ;)
[12:21] <Darkside> mm
[12:21] <Darkside> well the 4FSK modem was fun
[12:21] <adamgreig> yea
[12:21] <adamgreig> much better than 2fsk?
[12:22] <adamgreig> i was doing soft decisions from bpsk for that ldpc
[12:22] <Darkside> we did it just for the hel of it
[12:22] <Darkside> hell of it*
[12:22] <Darkside> not really sure it was any better
[12:22] <Darkside> i was doing 100 baud RTTY (for the other listeners), then 50 baud 4FSK with half the shift
[12:22] <craag> Pico launch from Epping Forest will be at 6pm
[12:22] <Darkside> so the upper and lower tones were in the same place as the RTTY tones
[12:23] <craag> Burst at ~19km
[12:23] <Darkside> looked cool on the waterfall :-)
[12:23] <craag> very slow ascent
[12:23] <Darkside> and weirded out some of the listeners
[12:23] <craag> see if we can make the dutch coast..

[12:24] <Darkside> i love voice keyers
[12:24] <Darkside> means i can chat on IRC and call CQ at the same time
[12:24] <craag> are you on a freq? there's quite a station here, wonder if they can hear you at all

[12:25] <Darkside> thatll be my only shot at hearing you on HF i expect
[12:25] <craag> ok, ping me on irc tomorrow then and we'll see
[12:26] <fsphil> I'll have a listen but I only have 5W so no way you're going to hear me
[12:26] Action: AndyEsser sets up a 20m antenna along the street
[12:26] <craag> we've got a 4-element beam at 80ft for 20m, with a '400W' PA
[12:26] <SIbot1> In real units: 80 ft = 24 m
[12:28] <Darkside> hehe
[12:28] <adamgreig> craag: pity, by the time it gets to the antenna you'll probably be down to 100W or so ;)
[12:28] <adamgreig> coax losses are a terrible thing
[12:28] <craag> adamgreig: well, it's 400W at the antenna ;)
[12:28] <adamgreig> ;)
[12:28] <Darkside> haha
[12:28] <Darkside> same here
[12:28] <Darkside> theres about 50m of LDF2-50 between me and the antenna
[12:28] <Darkside> wait
[12:28] <Darkside> more like 100m
[12:28] <Darkside> so yeah, <400W at the antenna feedpoint
[12:28] <Darkside> boo
[12:29] <Darkside> but i have 3 elements on 40m
[12:29] <Darkside> so meh

[14:43] <fsphil> richardeoin: are you replacing the RS codes or is this in addition to them?

[14:46] <richardeoin> this knows nothing about jpeg, but instead just treats the input as data
[14:47] <craag> hmm, didn't like that fencepost much, lock as soon as I picked it up off it
[14:47] <richardeoin> if you receive 2/3 or more of the packets the decoder gives you the packet back :)
[14:47] <richardeoin> otherwise it errors

[14:49] <richardeoin> should work quite well with multiple stations - if two stations have p=0.5 of receving a packet it'll succeed

[15:02] <adamgreig> richardeoin: if you get fewer than 2/3 of the packets, do you still get some full packets?
[15:02] <adamgreig> ie is it a systematic code and you still submit the systematic parts that come through?
[15:02] <adamgreig> I suppose for bpg that's poointless
[15:03] <adamgreig> but for jpeg it'd mean you still get partial and in-progress images
[15:03] <richardeoin> currently it checks if it has 2/3 and deliberately errors otherwise
[15:03] <richardeoin> but that could be changed
[15:03] <adamgreig> ok
[15:03] <adamgreig> is it a systematic code?
[15:03] <richardeoin> goign back to the 100 packet example
[15:04] <richardeoin> the 100 packets on the air are just the original data
[15:04] <adamgreig> and then 50 parity packets?
[15:04] <richardeoin> and then 50 parity
[15:04] <adamgreig> yea ok
[15:04] <richardeoin> yup
[15:04] <adamgreig> so you could upload any of the first 100
[15:04] <adamgreig> and get partials and in-progress jpegs
[15:04] <richardeoin> yep, that could be done
[15:05] <richardeoin> I haven't though
[15:05] <adamgreig> cool
[15:05] <adamgreig> did you look at raptor codes instead of block erasure codes?
[15:08] <richardeoin> brefily, but I found more resources for the block erasure codes - particularly the cm256 library
[15:08] <adamgreig> fair
[15:08] <richardeoin> hmm wikipedia says raptor codes can be both systematic and non systematic
[15:09] <richardeoin> that's probably the case for fountain codes generally?
[15:09] <adamgreig> yea I believe so

[15:10] <adamgreig> the only real advantage of a raptor code over your block erasure is you can just arbitrarily keep generating packets
[15:10] <adamgreig> they're rateless
[15:10] <adamgreig> but if you're set on a 2/3 rate then it doesn't make much odds I don't think...
[15:12] <richardeoin> I came to the 2/3 rate by looking at daveake's flight where the ARQ failed
[15:13] <richardeoin> the worst packet losses were around 25 - 30%
[15:13] <richardeoin> it's just something to try to start with, but I have no objections to changing it
[15:15] <richardeoin> fsphil: I made a pull request to lora gateway so it passes those two new packet types https://github.com/PiInTheSky/lora-gateway/pull/17
[15:15] <richardeoin> and the 0x67 No-FEC type, which is wasn't going
[15:15] <richardeoin> *doing
[15:16] <richardeoin> which was odd because it makes the FEC useless anyhow by discarding packets where the lora crc fails at the gateway
[15:16] <richardeoin> goodness that's a lot of trailing whitespace for one file

[18:42] <Upu> what baud rate is this ?

[18:43] <mfa298> gurlavie: I think the A+ are a bit scarce at the moment, but there might be more being made in the next month or two, should be a decent number of Zeros around now.
[18:45] <Upu> ok must be just a little too weak to decode
[18:45] <gurlavie> DigiKey has ~40 of the A+256M. What is zero?
[18:46] <mfa298> the Zero is similar hardware to the A+, but a much smaller size and shoudl be around $5.

[19:44] <Geoff-G8DHE_> It'll be more likely to collide with a Ferry than an aircraft by the time it gets to the land!
[19:45] <Geoff-G8DHE_> Think the prediction still thinksits climbing anyway
[19:45] <PE2BZ> set autofocus = on
[19:45] <PE2BZ> set relative humidity = 100%
[19:47] <bertrik> jarod: have you been monitoring this flight? the landing spot might be within reasonable driving range from where you live
[19:47] <bertrik> IF it lands
[19:48] <Geoff-G8DHE_> Think the prediction still things its climbing rather than burst hence the burst showing nearer land !
[19:52] <PE2BZ> It´s playing with us...
[19:53] <bertrik> BTW, i've seen a couple of projects developing a gnuradio plugin for LoRa now, I hope it eventually becomes useful for HAB decoding

[21:58] <Nemo_> Yeah, he sounded positive. :)
[21:58] <Nemo_> Called IiA in Cork, but machine answered saying human being responsible was on a leave
[21:59] <Nemo_> Will call on Monday again.
[21:59] <Nemo_> Any idea how could I solve the issue which is rendering my life miserable? Haha
[22:00] <fsphil> not without more data
[22:00] <Nemo_> I'm using Mr Stirk articles on the subject
[22:01] <Nemo_> In his website

[22:04] <Nemo__> The Internet of the place where I'm is crappy as well...
[22:04] <Nemo__> It disconnects periodically, apparently. So annoying...

[22:21] <Alz> Hello!
[22:25] <Alz> Im having a little problem decoding with DL fldigi. Using the PitS board and it's code, I successfuly decode the telemetry with the camera disabled. But if I activate the camera so it sends images, this happens: https://gyazo.com/0e69122150db77ee52cbfb310c89381d
[22:25] <Alz> It sends the images and the telemetry properly, but there's a lot of "text noise" (sorry if incorrect term) too (although the telemetry is there and it's correct)
[22:26] <Alz> Any ideas of a possible reason?
[22:27] <SM0ULC-Reb> does the telem and pic use the same baudrate? (not very knowalbe around the pits)
[22:27] <fsphil> the random text *is* the image
[22:27] <fsphil> the images are binary data, but fldigi tries to display them as text anyway
[22:32] <Alz> SM0ULC-Reb : I think so fsphil : I imagined as much. Is there a way for fldigi to not show the binary data as in the images from some tutorials?
[22:35] <fsphil> no. it doesn't know it's image data until it's received a full packet
[22:37] <fsphil> the images you've seen in the tutorials will not have been from payloads sending images
[22:38] <Alz> I see, thank you! (That's a pain tho)
[22:38] <fsphil> yeah it's a bit annoying
