[11:26] Shannon says additional bandwidth would improve performance a lot, but chirp mod isnt using "real" bandwidth [11:27] its just NBFM in put through some chirp processing [11:27] -in [11:28] theoretically optimal is probably really high data rate QPSK with a ton of FEC [11:28] the reason it works well in practice seems to be that you dont need accurate sync between tx and rx [11:28] or more realistically BPSK so you can track carrier with a Costas [11:28] exactly [11:28] you cant really get NBFM to work at 100bps or so [11:28] with modules [11:29] im currently 6dB off best LoRa 18bps budget using si446x at 200bps [11:29] and thats with no attempt at FEC [11:29] also shannon says using extra bandwidth gets you more capacity rather than SNR performance? [11:29] no [11:30] if you are power limited, Shannon says you need <<1bps/Hz [11:30] To quote father Jack FEC that's awesome. [11:30] oh right, use MFSK [11:30] but the Hz has to be a real bandwidth use, not a deceptive coding scheme like chirp [11:31] but any FSK is somewhat suboptimal [11:31] well its the same as DSSS? [11:31] hence my saying BPSK at really high rate [11:31] DSSS also gives you no real gain [11:31] yea thats what i was trying to say [11:31] yeah :P [11:32] Presumably this is in the face of a noiseless channel [11:32] DSSS can be good jam resistance wise [11:32] SpeedEvil: AWGN [11:32] well AWGN channel [11:32] yeah [11:32] A AWGN noiseless channel :) [11:32] I meant jam free [11:33] i suspect the best we could use on a HAB would be something like 2kbps BPSK with lots and lots of FEC [11:33] to get <500bps throughput [11:33] tbh i was putting out lora at 9600bps last monday and i was picking it up reliably [11:33] wow [11:33] Laurenceb: these nodes are bidirectional?

[11:50] if youre doing a few, might as well stick some big holes in it in case you need them [11:50] possibly with some glue holding it down. or is it best to use mounting holes? [11:50] I tried all the modes you were using 20k8 thru to 125KHz the 125KHz need you clear of the Downs the other modes I was receiving before you rose over the Downs themselves [11:50] at the very least you could put a hole each side of JP1 [11:51] ok good idea as its dead space. what size mounting hole is usual?

[14:40] yes [14:41] that's a good news for me in that case that mean I may be able to emit APRS packets from sx1276 [14:42] in theory you just have to emit a clear carrier. you are then modulating the reference crystal. thats how many persons do it [14:43] Nick change: Family -> Lammergeier [14:43] so for example for APRS on 144.800 [14:43] I may use 144.801200 for FSK [14:43] and 1000Hz deviation ?

[15:10] so do you think there is a way to module AFSK for APRS using a FSK modem? [15:13] back to basics.... For FSK, you are shifting the actual TX frequency as you key the 1's and 0's of the data. eg. between 0 = 434.650000 and 1 = 434.65400 That would be a 400Hz shift FSK [15:13] maounis (~textual@HSI-KBW-46-237-220-35.hsi.kabel-badenwuerttemberg.de) joined #highaltitude.

[15:20] what cragg was suggesting was, on a TX that must be commended to change RF freq, you could add a verical diode to the reference crystal, to make it like an NTX2, where you can waggle the RF TX with a voltage [15:20] vericap [15:20] varicap [15:20] ok I understand [15:21] (I can't type today) [15:21] "today" is about the only word you *can* type :) [15:21] maounis (~textual@HSI-KBW-46-237-220-35.hsi.kabel-badenwuerttemberg.de) joined #highaltitude.

[15:22] AFSK is not fer efficient in terms of TX power [15:22] very [15:23] I start to understand what it is less efficient now [15:23] in the UK, we are not allowed to use AR airborne, so we don't even try. [15:23] I'm living in south of france [15:24] and only the 144.650Mhz frequency is allowed airborne for HAM [15:24] AFSK is using a lot of power to send the audio tone, which itself carries no data [15:24] for my first launch, I used 10W APRS tracker!! [15:24] I know it is a total waster of power [15:24] Leo used 16mW or something :P [15:25] the only advantage for AFSK is, that you can RX it with cheap FM receivers and there is the APRS network in place. [15:25] so I'm planning to use lora tracker for my next launches using 50mw [15:25] we are not allowed to use the APRS network for airborne also [15:25] But the UKHAS guys have their own rx network that is better suited to balloons [15:26] I had to use 144.650 instead of 144.800 which is not allowed airborne [15:26] I can't comment on lora, I've not tried it yet. Others will reply I expect [15:26] I have a 144.650Mhz LoRa tracker which start to work well now [15:27] I was thinking about the secondardy tracker , if I can use APRS or RTTY with 50 baud FSK [15:27] and now I think that I have my answer :) [15:27] on 434MHz there is plenty of AR equipment, which makes it easier. And lots of hams already set up for it. Just needing to run the dl-fldigi. [15:28] New antenna sponsor http://i.imgur.com/9cTfpoU.jpg [15:28] yes I know that 434 Mhz is the best freq to use, but it is not allowed in France :( [15:28] Nick change: Elwell_ -> Elwell [15:28] so I had to use the 144.650 [15:28] the only advantage I can see is that there is no limit on the tx power [15:29] chrisstubbs Is that the listening bank? [15:29] but there is no network like in the UK with ukhas [15:29] not allowed, even in the licence exempt band?? [15:29] yes that 's the current status gonzo_ [15:29] it only needs to get a few ham stations to listen and you have tracking [15:30] ok, understand [15:30] drsnik_ (~drsnik@gate3.ima.cz) joined #highaltitude. [15:30] I have recovered my first flight with my home station and mobile chasing car [15:30] but it was with 10W APRS :) [15:31] I'm still confident that using LoRA at 50mw will be enough for recovering my payload with 3/4 stations [15:31] We were using LoRa last week, at 10mW, at 9600 baud :) [15:31] Worked fine from the chasecar [15:32] without yagi?

[23:05] I created [23:05] the flight documents ... [23:05] Who can approve ? :) [23:06] anerdev2, post the ID in #habhub [23:07] ok .. [23:07] but can you indicate me if I make all correct ? [23:08] chrisstubbs Flight ASSM1 Launch (1ca2, not approved, 1 payload) not approved -___- [23:08] someone will approve it [23:09] but they may ask you to test the payload doc first [23:09] eg power your tracker up and get it on the map [23:09] ok ... but will contact me on irc or via email ? [23:10] irc [23:10] test the payload now if you can [23:10] Now I can't [23:10] tomorrow yes .. [23:10] I have a little problem with time string [23:11] so, I made an error .. In the flight documents there are two "ASSM" [23:11] there are two "ASSM1 Launch" [23:11] can I delete ? [23:12] No you can only create a new one if there is an error [23:12] ok ok perfect [23:12] and habitat will use the latest [23:13] for set the dl-fldigi I need to use this tutorial: http://ukhas.org.uk/guides:tracking_guide [23:13] maounis (~textual@HSI-KBW-46-237-220-2.hsi.kabel-badenwuerttemberg.de) joined #highaltitude. [23:13] ? [23:13] you will then need to re-create your flight doc to reflect the new payload doc [23:13] (check the dates down the right hand side to pick the latest) [23:14] yes that tutorial [23:14] perfect ... [23:14] But I have only a little answer [23:15] this is good: http://i.imgur.com/OV0afux.png ? [23:15] because only the callsign field and checksum are aactived ... [23:16] ah yeah that is normal (i think) [23:16] because there are the lat, lon, alt value in the string but not in the field .. [23:16] fix your problem with the time string [23:17] if you can get it on the map then you should be on the right track to having things working [23:17] yep .. [23:17] but Can I test the payload tracking from home ? [23:17] if all is ok with transmission ? [23:17] yeah [23:18] it should appear on spacenear.us if your payload doc is correct and dl-fldigi is configured [23:18] ook ook [23:18] and you have decoded a valid string [23:18] I have only a problem with time string -___- I don't understand why the value are incompressible [23:19] I don't think that is a Ram problem ... [23:19] because the SIm908 have a char time like this: 20150225134550 [23:20] and I have two method for split , that work alone ... but doesn't work with my arduino sketch [23:20] but for the station, what call sign can I use ? [23:26] You can use any callsign in dl-fldigi [23:26] nickname etc [23:26] as for the coding problem, save that for tomorrow when more people are around. I better be off now [23:27] gonzo_nb (~gonzo@host-92-14-209-118.as43234.net) left irc: Remote host closed the connection [23:27] also your signal in dl-fldigi looks a bit funky, did you have an antenna connected? [23:30] also there is an empty field at the end of the string just before checksum.. [23:32] ok ok [23:32] thank you guys .. Tomorrow I will made correction =D [23:32] have a good night [23:32] anerdev2 (~anerdev@2.234.169.198) left irc: Quit: Leaving [23:33] KF5WYX (~Craig@2605:6000:ef85:c200:696e:4b93:5b07:25be) left irc: Ping timeout: 256 seconds [23:36] maounis (~textual@HSI-KBW-46-237-220-2.hsi.kabel-badenwuerttemberg.de) left irc: Quit: My Mac has gone to sleep.
