[00:01] <F1VJQ> Yes, I think so... and they float at about 12.5km
[00:02] <nigelvh> Yeah
[00:02] <F1VJQ> UK - Canada so far is 14 days and over 20,700km
[00:03] <nigelvh> Perhaps one of these days I'll have to send out a floater and give it a try.

[00:03] <F1VJQ> distance calculated from position to position.... lat/long
[00:04] <nigelvh> Yeah, actual distance will be somewhat farther.

[02:36] <arko> hehe
[02:37] <arko> im stuck here with my pcbs in limbo
[02:37] <nigelvh> Yeah?
[02:37] <arko> not sure if hackvana actually shipped them or not :/
[02:37] <arko> he keeps telling me "its shipping tomorrow"
[02:37] <arko> im just writing software now without the hardware :|
[02:38] <nigelvh> Hmm. I haven't used hackvana. I use OshPark and he gets them to me VERY quickly.
[02:39] <arko> i like hackvana as a person, he's super reachable and cool
[02:40] <arko> and way affordabled, so i rather give him my business, but i think for higher priority stuff im gonna shell the cash out for it

[02:43] <aadamson> arko, so I think the problem is he uses goodluckbuy to ship and they aren't that reliable
[02:43] <aadamson> I had the same problem on my boards from hack
[02:43] <arko> he just switched
[02:43] <aadamson> oh really
[02:43] <aadamson> that's good
[02:43] <aadamson> mine got stuck the same way
[02:43] <arko> yeah, i happened to order right at the switch
[02:43] <aadamson> and I paid expidited shipping too
[02:43] <aadamson> which still as it all turned out was a really good deal
[02:44] <arko> me too, but that only matters when he has it in his hands
[02:44] <arko> yeah totally
[02:44] <arko> low cost is great
[02:45] <arko> he probably could pull in loads more money if he got his supply chain into a well lubricated machine
[02:45] <aadamson> yes I agree
[02:45] <aadamson> I was still very pleased with the product and I had only used oshpark prior.
[02:45] <aadamson> reason I went to hack was I wanted .8mm boards
[02:46] <arko> yeah, i want to get finer pitch traces now
[02:46] <arko> start doing BGA
[02:46] <aadamson> oh my... what are you using for reflow?
[02:46] <arko> the cost is huge but man you can build so much
[02:47] <arko> so tiny
[02:47] <arko> let me find the model
[02:47] <aadamson> I use one of these and a walmart special
[02:47] <aadamson> are you using that 962A or what ever it is?
[02:47] <arko> T-862
[02:48] <arko> for IR
[02:48] <aadamson> ah the heated board thing, not an oven... yeah IR
[02:48] <arko> but for hotplating i use MAdell Quick870
[02:48] <arko> all the ovens ive tried have been terrible
[02:49] <aadamson> I seem to have got lucky
[02:49] <aadamson> I guess with my oven
[02:49] <arko> nice
[02:49] <arko> which model?
[02:49] <aadamson> it's a 1500watt and with that controller and a SSR, it works
[02:49] <aadamson> it's really old, I don't remember
[02:49] <aadamson> I've had it for a few years
[02:49] <arko> ah i see
[02:49] <aadamson> thermocouple and that arduino board and it follows the profile *OK*, not perfect, but not terrible either
[02:50] <arko> im probably going to buy a metcal reflow station some day
[02:50] <aadamson> but I also *only* use the kester easy profile 256 solder paste.
[02:50] <arko> i wish they made a hot plate :/
[02:50] <aadamson> yeah I have a metcal soldering/tweezer station and I'd be so lost if I didn't have!
[02:50] <arko> Metcal 4 Lyf
[02:51] <arko> we have at least 20-25 metcals at our hackerspace
[02:51] <arko> we love em
[02:52] <aadamson> yeah, they are awesome, instant and with the right tips, they can do miracles :)
[02:53] <arko> hurray currie point
[03:02] <myself> jeez, we have room for like 4 soldering stations and that's about all the lab can hold, elbows-wise
[03:03] <arko> :P
[03:03] <myself> but then we have a 15HP CNC mill in back, so, we've divided out space a little differently :P

[04:29] <arko> good god its annoying to setup aprsis
[04:29] <nigelvh> Yes
[04:29] <nigelvh> Most of the programs are excruciatingly outdated.
[04:29] <arko> ok i need help
[04:30] <arko> so outdated and terrible
[04:30] <arko> i have a virtual audio port
[04:30] <arko> no problem
[04:30] <arko> i got AGW setup
[04:30] <arko> and made a comport
[04:30] <arko> except i dont see it in device manager
[04:32] <nigelvh> So, I have AGWPE set up with the "Winsock" interface, and then APRSIS32 connects to that.
[04:32] <arko> nigelvh: any ideas/?
[04:32] <arko> oh
[04:33] <nigelvh> And AGWPE just listens to the audio card.
[04:33] <arko> right
[04:33] <arko> how did you create a winsock interface?
[04:33] <arko> oh wait i think i see it
[04:33] <nigelvh> If you right click the AGWPE icon, there's a Setup Interfaces option
[04:33] <arko> enable winsock tcp/ip
[04:33] <nigelvh> And then there's a checkbox there
[04:33] <nigelvh> Yeah
[04:35] <arko> how can i tell with aprsis32 if im actually rx'ing a station?
[04:35] <nigelvh> I assume you mean RXing over the air?
[04:35] <arko> yeah, im using the rtl usb
[04:35] <arko> so rx only
[04:35] <arko> i see all these aprs beacons showing up
[04:35] <arko> but i think it's getting these fromt he inter
[04:36] <arko> from the*
[04:36] <nigelvh> Yeah, so under view, I think you can click none, then click on RF->All
[04:37] <arko> blah
[04:37] <nigelvh> Seems mine is defaulting to showing me what I hear directly and what I iGate
[04:37] <arko> just as i suspected
[04:37] <arko> nada
[04:37] <arko> so i created a port of AGW
[04:37] <arko> set the ip to and the port to 8000
[04:37] <arko> it didnt complain
[04:38] <nigelvh> I used "localhost"
[04:38] <nigelvh> The top left corner of APRSIS32 should say APRS-IS OK and AGWPE OK alternating.
[04:38] <nigelvh> For the two ports it's connected to.
[04:38] <arko> yeah it does
[04:38] <arko> WOAH!

[04:39] <arko> thanks nigelvh
[04:39] <arko> :)
[04:39] <nigelvh> The other thing you can do is right click the AGWPE icon, and use the sound card tuning aid to get your volume levels right.
[04:39] <arko> yeah that was the issue
[04:39] <arko> volume was to loud
[04:39] <nigelvh> I use the sine wave display, and try to get it so most packets aren't quite clipping.
[04:39] <arko> looked at the wave forme
[04:40] <arko> so does this program automatically upload to the aprs network?
[04:40] <nigelvh> Also, (unfortunately) I have found that AGWPE isn't the best packet decoder. Other programs like MixW decode much better, but I haven't figured out how to use that for an iGate.

[04:42] <arko> 4 different programs to do one simple thing
[04:42] <nigelvh> So, there's Config->General where you put in your callsign and your APRS-IS "passcode", and there's your APRS-IS port where you configure what kinds of packets you'll forward to that port.
[04:44] <arko> whats a passcode?
[04:44] <nigelvh> To upload to the APRS-IS network you have to have a passcode. If you don't have yours, I can generate one for you.
[04:44] <arko> i think i found a generator
[04:44] <nigelvh> Yeah, it's kinda public knowledge

[06:55] <LeoBodnar> and for two days could not squeeze in :(
[06:55] <LeoBodnar> very discouraging
[06:56] <nigelvh> Yeah, even with favorable network conditions, I don't win the race for the majority of packets I hear OTA
[06:56] <jededu> In the output string $$ ect are the $$ included in the CRC-16 checksum ?
[06:56] <LeoBodnar> nigelvh why many servers cut off connections on a regular basis?

[06:57] <nigelvh> Is it dropping you? Does it seem on a regular/on purpose basis?
[06:57] <LeoBodnar> i usually have 5-10 disconnects and reconnects a day
[06:57] <nigelvh> Oh man, that's no good.
[06:57] <LeoBodnar> seems random and not specific server
[06:57] <LeoBodnar> i have used asia.tier2
[06:57] <LeoBodnar> alias
[06:57] <nigelvh> Yeah, it shouldn't do that. And your internet in general isn't flakey?
[06:57] <LeoBodnar> it rotates stuff
[06:57] <LeoBodnar> no rock solid
[06:57] <nigelvh> Hrm...
[06:58] <LeoBodnar> i'll try yours
[06:58] <nigelvh> Well, if you want to try our server, despite it being across the world, it's northwest.aprs2.net
[06:58] <LeoBodnar> i don't think location matters much
[06:58] <nigelvh> http://northwest.aprs2.net:14501/
[06:58] <LeoBodnar> it's only a few 10kbps of traffic
[06:58] <LeoBodnar> thanks, i will try next time i fire up DireWolf
[06:59] <LeoBodnar> 14501 is standard aprs-is port?
[06:59] <sp2ipt> LeoBodnar: continous ping to the serve might help ;)
[06:59] <LeoBodnar> i have used rotating alias
[06:59] <nigelvh> Yeah, we have this server conveniently located right on our network edge with some nice peering, so it's got good connectivity
[06:59] <DL7AD> nigelvh: there's NOCALL-1 active!

[10:03] Laurenceb (~Laurence@host86-167-154-80.range86-167.btcentralplus.com) left irc: Ping timeout: 250 seconds
[10:03] <Darkside> wideband
[10:03] <Darkside> unless you do things weird in the UK
[10:03] <Maxell> astrobiologist: here in the EU it's wide fm (12,5 kHz)
[10:05] <LeoBodnar> narrowband
[10:05] <LeoBodnar> wideband is broadcast FM
[10:05] <Darkside> LeoBodnar: depends on your definition of narrow/wide
[10:06] <Darkside> in th commercial FM world, Narrow is 2.5KHZ deviation, Wide is 5KHZ deviation
[10:06] <Darkside> with according occupied bandwidths and channel spacings
[10:06] <Maxell> LeoBodnar: you have broadcast wide (200 kHz?)and narrow fm wide/narrow (12,5 kHz and 6,25 kHz)
[10:07] <Darkside> Maxell: those are the channl spacings
[10:07] <LeoBodnar> WFM (1 kHz/52.5 kHz Dev.; 12 dB SINAD)
[10:07] <Darkside> not the occupied bandwidths
[10:07] <LeoBodnar> from my IC-R20 manual
[10:07] <Maxell> hmmm
[10:07] <astrobiologist> my manual says my handheld operates in normal FM deviation (+- 5khz) or narrow band FM deviation (+- 2.S khz) so which should I pick?
[10:07] <Darkside> astrobiologist: wide.
[10:07] <Darkside> well, 'normal'
[10:07] <LeoBodnar> normal != wide
[10:08] <Darkside> LeoBodnar: depends where you look
[10:08] <Darkside> astrobiologist: use normal.
[10:08] <F1VJQ> B-64 crossed US coastline at 23:41 utc
[10:09] <astrobiologist> so which should I pick from the ones on my handheld for aprs? I'm trying narrow (+- 2.5 Khz) at the moment
[10:09] <Darkside> LeoBodnar: what you are reading in your IC-R20 manual tells you what the deviatiosn are for whatver icom dcided to call their internal modes
[10:09] <Darkside> astrobiologist: NORMAL.
[10:09] <LeoBodnar> *NORMAL*!
[10:09] <Darkside> i only said it 3 times :P
[10:09] <Darkside> jeez
[10:09] <Maxell> F1VJQ: b-64 in us?
[10:09] <F1VJQ> Maxell yes
[10:10] <Maxell> awesome
[10:10] <F1VJQ> Maxell travelling east from UK
[10:10] <LeoBodnar> well i try to simplify
[10:10] <F1VJQ> Maxell actually B-63 and B-64 are both in Canada at the moment
[10:11] <LeoBodnar> WFM is broadcast FM in gqrx as well
[10:11] <Darkside> diffrent 'standards'
[10:11] <Darkside> for 'land-mobile' FM, you have wide and narrow
[10:11] <Darkside> broadcast FM is kind of a different category
[10:11] <LeoBodnar> confusion stems from 12.5kHz channeling pushed in europe
[10:11] <Darkside> yeah channel spacing has little to do with deviation
[10:11] <astrobiologist> OK guys I'm back on +-5Khz, "normal".
[10:11] <LeoBodnar> what used to be narrow is suddenly "normal"
[10:12] <Darkside> LeoBodnar: yeah because you guys have such a tiny 2m band
[10:12] <LeoBodnar> nobody cares
[10:12] <LeoBodnar> 25kHz is still normal
[10:12] <Darkside> but APRS would still be 'wide' (5KHZ deviation) to support lgacy gear
[10:12] <astrobiologist> I left it on +-5Khz all night and just a couple of times I got digipeated
[10:12] <F1VJQ> actually 2MHz is a lot... it is/was 25kHz spacing and FM that are the waste of space
[10:12] <Darkside> astrobiologist: thats probably saying more about your antenna setup than your deviation
[10:13] <astrobiologist> but really just a couple of packets. so I have been trying narrow too
[10:13] <Darkside> astrobiologist: on narrow you'll be seen as underdeviating
[10:13] <Darkside> if you didn't get *any* packets through on wide then i'd be wondering whats going on
[10:13] ak4rp (~hp@ joined #highaltitude.
[10:13] <Darkside> ugh
[10:14] <Darkside> ok, googled
[10:14] <mattbrejza> on aprs.fi how do you see all the packets an igate has received?
[10:14] <astrobiologist> I can receive packets readily. the rx seems fine. I can't tx though by the looks of it
[10:14] <Darkside> UK apparently uses 'narrow' deviation for APRS
[10:14] <Darkside> ffs
[10:14] <Darkside> y u so diffrent
[10:14] <Darkside> astrobiologist: set it to narrow, sorry...
[10:14] <Darkside> here's me thinking UK APRS would be like the rest of the world
[10:14] <Darkside> nop
[10:14] <Darkside> nope*
[10:15] <gonzo_> narrow? you mean dev for 12.5khz chans?
[10:15] <Darkside> gonzo_: 2.5KHZ deviation
[10:15] <Darkside> forget about the channl spacing
[10:15] <astrobiologist> darkside: ur confusing me! :-) +-2.5 or +-5 for aprs in the U.K?
[10:15] <astrobiologist> OK I'm going back to NARROW +-2.5
[10:15] <Darkside> astrobiologist: suppoedly its +-2.5KHz
[10:16] <Darkside> from what i'm reading in a few places anyway
[10:16] <LeoBodnar> i have flown 20 HABs with 1.2kHz deviation by mistake
[10:16] <astrobiologist> I'm passing stonehenge. anybody nearby who could listen out for my packets?
[10:16] <gonzo_> the dev needs to be narrow enough to fit through the chan filters on the rx
[10:16] <LeoBodnar> on APRS signal
[10:16] <Darkside> LeoBodnar: hah
[10:16] <LeoBodnar> up to 750km range
[10:17] <LeoBodnar> one went to Japan
[10:17] <gonzo_> I can't remember the std dev's. Is 2.5KHz+- narrow even for 12.5 filters?
[10:17] <Darkside> LeoBodnar: sure, it'll just be a lower level at the output of the receiver
[10:17] <Darkside> gonzo_: the filters arent 12.5KHz wide
[10:17] <LeoBodnar> i was aiming at 3.5kHz but got it wrong by a factor of 3
[10:17] <daveake> You'll get this stuff right one day Leo :p
[10:17] <Darkside> for 2.5KHz deviation the occupied bandwidth is 10KHz wide, for 'wide' its something like 16KHz
[10:17] <LeoBodnar> as on 144MHz PLL channel step is 1/3 of 434
[10:17] <LeoBodnar> lol
[10:18] <Darkside> LeoBodnar: you might want to consider changing the deviation in different aras
[10:18] <Darkside> areas*
[10:18] <Darkside> i.e. in R3 we'd be using 5KHz deviation
[10:18] <F1VJQ> LeoBodnar - a buguette of sorts
[10:18] <daveake> mm baguette
[10:18] <Darkside> and if you run at 2.5KHz, there'll be a lot of aprs igates/digi's that won't hear you properly
[10:18] <gonzo_> Darkside, what's the filter width for a 12.5kHz spacing then?
[10:18] <F1VJQ> bugette (sic)
[10:18] <Darkside> gonzo_: 10KHz i think
[10:19] <LeoBodnar> +-3.5kHz peak works well everywhere
[10:19] <LeoBodnar> as we see on B-63+
[10:19] <gonzo_> sounds sensible. Only seen radio sspeced for 12.5 channeling. Never loked at the actual filter BW apart fro ssb kit
[10:19] <Darkside> one flight is not proof
[10:19] <Darkside> LeoBodnar: some narrow receivers will mute with >2.5KHz deviation
[10:20] <Darkside> not all, but some
[10:20] <Darkside> you're probably just being gated by the ones that don't mute
[10:20] <LeoBodnar> well i might throttle back to +-2.5kHz
[10:20] <GW8RAK> For 12.5KHz spacing, IIRC, the filter bandwidth is 6KHz
[10:20] <Darkside> LeoBodnar: 2.5KHz would be a safe bet for sure
[10:20] <gonzo_> the BW is going to be the 3dB points I expect
[10:21] <gonzo_> so there will be roll off to the next cnan
[10:21] <gonzo_> chan
[10:21] <Darkside> LeoBodnar: if you can toggl it in software i'd switch it up to 5KHz in some countries
[10:21] <Darkside> probably safe to have it run at 2.5KHz in IARU region 1, and 5KHZ in rgions 2 and 3
[10:22] <LeoBodnar> 1.2 worked brilliantly so i am not really bothered too much
[10:22] <gonzo_> do a narrow then a wide
[10:22] <LeoBodnar> i do proper pre-emphasis so it might help
[10:22] <Darkside> LeoBodnar: i'm just suggesting you conform to local 'standards'
[10:22] <Darkside> which will rais your chances of getting a packet received
[10:22] <Darkside> by *all* igates, not just ones that happen to work with a low deviation signal
[10:23] <gonzo_> for .it that means a 1kW with echo
[10:23] <Darkside> if you're changing frequncy anyway, changing deviation at the same time shouldn't be difficult?
[10:23] <Darkside> gonzo_: bahaha
[10:23] <LeoBodnar> i can't complain for now
[10:23] <Darkside> gonzo_: same for spain
[10:23] <Darkside> gonzo_: spain doesn't have power limits
[10:24] <LeoBodnar> i'll probably have interleaved packets with different deviation and compare the success rate
[10:24] <LeoBodnar> or more probably i won't bother
[10:24] <Darkside> set it to 2.5KHz and leav it
[10:24] <LeoBodnar> indeed
[10:24] <Darkside> should work fine everywhere
[10:24] <LeoBodnar> yep
[10:24] astrobiologist (~astrobiol@ left irc: Read error: Connection reset by peer
[10:25] <LeoBodnar> i wonder what deviation makes best SNR
[10:25] astrobiologist (~astrobiol@ joined #highaltitude.
[10:25] <LeoBodnar> it is very demod dependednt
[10:25] <Darkside> probably one that fits within the filter bandwidth i'd guess
[10:26] <gonzo_> feels like it should be the widest that the chan will allow.
[10:26] <Darkside> yeah
[10:26] <LeoBodnar> but it should plateu
[10:26] <nats`> don't agree
[10:26] <Darkside> if its too low for a given filter bandwidth, you'll get more noise in, right?
[10:26] <nats`> it means higher noise floor
[10:26] <LeoBodnar> plateu and drop off as deviation increases
[10:26] <Darkside> nats`: i mean, narrow filters mean better SNR performance, sure
[10:27] <Darkside> but for a *given* receiver filter bandwidth, you'd be best to occupy it for FM
[10:27] <nats`> Darkside one technique is to widen input filter and do a parametric filter behind
[10:27] <nats`> to narrow it and recenter the Fc
[10:27] <Darkside> nats`: we'r talking commercial FM receivers here
[10:27] <Darkside> not custom stuff
[10:27] <astrobiologist> I managed to transmit an aprs packet on +-5khz deviation last night. so why did that work if I wasn't on +-2.5 then?
[10:27] <Darkside> astrobiologist: som recivers will still receive
[10:28] <Darkside> astrobiologist: or someone has their recivre on th wrong setting, which is also likly :P
[10:28] <nats`> Darkside we could apply same rule as MSK
[10:28] <astrobiologist> darkside: it was a local digipeater so less likely
[10:28] SiC (~Simon@ joined #highaltitude.
[10:28] <gonzo_> if the rx site has wide filters, your packets will just be loud. If they have narrow filters it will clip and distort. Proabbly being seen as noise, so the squelch may close
[10:29] <Darkside> nats`: FM analysis is painful
[10:29] <Darkside> devolves into bessel function crap which i cant remember
[10:30] <gonzo_> been a long time since I did that. The maths all evapourated years ahgo
[10:30] <astrobiologist> anyway I'm on +- 2.5khz now but it hasn't seemed to help (nobody digipeating me to an igate even though I could receive a lot of other packets)
[10:30] <Darkside> astrobiologist: could mean many things
[10:30] <Darkside> astrobiologist: could mean other stations are overpowering your signal
[10:30] <gonzo_> you need a local RX (on your bench)
[10:30] <astrobiologist> I am not rx'ing packets right now, suspect I'm out in the sticks anyway (salisbury plain)
[10:31] <Darkside> astrobiologist: what tx antenna and power are you using?
[10:31] <astrobiologist> gonzo_: may possibly have ordered another handheld on ebay ;-)
[10:31] <astrobiologist> darkside: just handheld's own rubber duck. 5w

[10:33] <astrobiologist> darkside: but quite typical for mobile aprs surely?
[10:33] <Darkside> astrobiologist: not with a handheld rubber duck
[10:33] <Darkside> you'll usually have a much higher gain antenna
[10:34] <Darkside> i use 5W in my car, and i use an antenna with about 5dBi gain on 2m
[10:34] <Darkside> but theres lot of digipeaters near me so it doesnt matter anyway
[10:34] <Darkside> i know people in th country who run 25W of APRS in their cars, into similar antennas
[10:35] <astrobiologist> haven't noticed much difference between the rubber duck and a telescopic whip I have too
[10:35] <Darkside> well no
[10:35] <Darkside> the telescopic whip wont have much more gain anyway
[10:35] <Darkside> best it can do is approximate a 1/4 wave
[10:36] <astrobiologist> 25W yikes! but how does balloon aprs work so well then?
[10:36] <Darkside> because it has LOS
[10:36] <Darkside> you don't
[10:36] <Darkside> also a balloon signal will get clobbered by local signals anyway
[10:37] <gonzo_> if you are in the vehicle, I think you can use what you want in the uk. unattended is limited, prob 25W eirp, for a duration
[10:38] <gonzo_> but a balloonn will be heard by more aprs stations, so hopefyllt they will not tx over it
[10:38] <gonzo_> (that assumes stations fo a listen for clear before tx)
[10:40] <gonzo_> you can get telescopic 5.8th wave antennas. But they are a bit unwieldy and I'd worry about breakling the radio connector

[10:45] <astrobiologist> giving up for now anyway because the nipper needs the iPad to watch a movie!
[10:46] <astrobiologist> I had ordered a magmount but it didn't turn up in time...
[10:46] <astrobiologist> will carry on tx at +-2.5Khz later
[10:46] <astrobiologist> so what sort of rig do people out in their cars etc then? what wattage is the yaesu 817?
[10:48] <craag> Hi astrobiologist
[10:48] <craag> A lot of people use an off-the-shelf tinytrak or similr
[10:49] <Darkside> i use an old kenwood handheld
[10:49] <Darkside> dos 5W
[10:49] <Darkside> does*
[10:49] <Darkside> it would be a waste using an 817 for APRS
[10:49] <craag> Most other people here use an old yaesu car rig
[10:49] <Darkside> yeah, old radios ar ea good move - the receive current is usually low, and thats also important
[10:49] <astrobiologist> darkside do you have one of the kenwood handheld with built in gps and aprs?
[10:49] <Upu> I use a UV5R
[10:50] <Darkside> astrobiologist: yeah i have on of those as well, but its not what i use in my car
[10:50] <Darkside> in my car, i have an old handhld (TH-215E) and an OpenTrackr USB
[10:50] <Darkside> OpenTracker*
[10:50] <craag> The raynet guys here use 20W+ for aprs
[10:51] <craag> I used my handheld last time though it it worked better :)
[10:51] <craag> *and it
[10:51] <Darkside> when i finally gt a kenwood TM-D710G i'll be using 25W :-)
[10:51] <astrobiologist> I am usually mobile on public transport only
[10:51] <astrobiologist> so my little th-f7e is good
[10:51] <astrobiologist> and since it can receive ssb I was hoping to use it for hab too
[10:51] <astrobiologist> hence attempts to bodge a cable
[10:52] <Darkside> if you're putting APRS in a car, you put APRS in the car. you get a dedicated radio
[10:52] <Darkside> a UV-5R will work fine
[10:52] <Darkside> dont use somehting you're going to want to take out often to use for other things
[10:52] <craag> If you're after something man-portable - a board with a gps,avr and hx1 might be more suitable.
[10:52] <craag> run off AAs
[10:52] <Darkside> craag: not enough power i've found
[10:53] <mattbrejza> craag: fyi ASTRA is currently igating
[10:53] <astrobiologist> hmmm if everybody else out there is using 1/4 waves at 25w am I basically being swamped out? do the digipeaters have theit squelch set quite high?
[10:53] <craag> mattbrejza: Cool
[10:53] <Darkside> craag: i've made what you're suggsting, and flown them on balloons
[10:53] <Darkside> craag: they work fine on balloons, crap on the ground
[10:53] <craag> Yeah we're a bit spoilt in soton with an LOS igate on the isle of wight
[10:54] <craag> last time I tried, 5W worked from lecture theatres :P
[10:54] <Darkside> pff
[10:54] <mattbrejza> so far nothing is on aprs.fi as its 3rd information when it gets to me
[10:54] <astrobiologist> craag: I had been tx-ing packets on +-5Khz not +-2.5Khz, in your experience would that have made a big difference?
[10:55] <craag> Nope
[10:55] <Darkside> craag: oh? i read APRS in th UK is 2.5KHz deviation
[10:55] <craag> It's supposed to be
[10:55] <Darkside> craag: so 5KHz dviation would distort
[10:55] <craag> Most of it isn't
[10:55] <Darkside> oh, so its a mess?
[10:55] <Darkside> hah
[10:56] <craag> You can clearly hear the different ones coming through!
[10:56] <LeoBodnar> it's "recommended"
[10:56] <LeoBodnar> but nobody knows it is
[10:56] <craag> Yeah, the portsmouth digipeater last I heard was still running the firmware that occasionally repeats hours-old packets too
[10:57] <Darkside> craag: what tncs are they using?
[10:57] <Darkside> old MFJ ones?
[10:57] <craag> I can't remember offhand - gave up on it all a while ago
[10:57] <astrobiologist> craag: I had just a couple of packets get through to the winchester digipeater but nothing else
[10:57] <astrobiologist> I tried again from the car at +-2.5Khz but nobody picked me up
[10:57] <craag> astrobiologist: Hmm, do you use have an rtl-sdr to listen to your own beacon?
[10:58] <astrobiologist> craag: no, no other receiver. I have ordered a cheap baofeng actually, should arrive by the time I get back!

[11:01] <astrobiologist> craag: what is so frustrating is that at least a couple of the packets did get through, so it is not a total problem, something more subtle! (packets too quiet? distorted? etc)
[11:01] <craag> astrobiologist: Are you using VOX?
[11:01] <craag> to key the rig?
[11:01] <astrobiologist> craag; yes I am using vox
[11:02] <craag> How long is your preamble tone?
[11:02] <Maxell> make sure there is suffcient preamble to open the vox
[11:02] <Darkside> snap
[11:02] <craag> ;)
[11:02] <astrobiologist> the preamble is set to 500msecs
[11:02] <craag> longer pls
[11:02] <Maxell> More then suffcient
[11:02] <Maxell> are you sure craag ?
[11:02] <LeoBodnar> jeez
[11:02] <LeoBodnar> i use 100ms
[11:02] <LeoBodnar> and it is still too long
[11:02] <Maxell> But not for vox LeoBodnar
[11:02] <LeoBodnar> ah, sorry correct
[11:02] <craag> My wouxon needs >500ms jsut to wake up
[11:03] <astrobiologist> for that matter I have a postamble set on the handheld to stop the vox turning off too soon
[11:03] <craag> I usually use 750
[11:03] <LeoBodnar> i meant on-air
[11:03] <Maxell> craag: my baofeng would do 350 ms

[11:11] <Maxell> ssb aprs eek
[11:11] <LeoBodnar> what's wrong with that?
[11:11] <Maxell> requires some good tuning
[11:11] <LeoBodnar> it's just FSK
[11:12] <gonzo_> afsk?
[11:12] <LeoBodnar> FSK
[11:12] <Darkside> none of the APRS receivers have decent tracking
[11:12] <Darkside> as in, frequency correction
[11:12] <Darkside> so you need to be spot on in frequency
[11:12] <LeoBodnar> they have quite wide tone filters
[11:12] <LeoBodnar> +- 100Hz is ok
[11:12] <Maxell> Upu: haat is still not updated? :)
[11:12] <Darkside> this is why FM is used, as mobil doppler can be pretty bad
[11:12] <Darkside> mobile*
[11:12] <Upu> I have no idea how to change it Maxell
[11:13] <LeoBodnar> Doppler?
[11:13] <Darkside> yup
[11:13] <gonzo_> aprs is simp-le afsk ax25 isn't it?
[11:13] <Upu> it was transmitted by some program I used ages ago and I can't work out how to change it
[11:13] <Maxell> yeah mobile flutter/stuff/buildings
[11:13] <Darkside> doppler shift too
[11:13] <LeoBodnar> please don't call it Doppler
[11:13] <Maxell> Upu: oh you just build your own phg code
[11:13] <Darkside> not sure how significant the doppler shift is
[11:13] <LeoBodnar> 0.1Hz
[11:13] <Upu> Sure it is that easy :)
[11:13] <Darkside> but apparently its noticable on SSB
[11:13] <LeoBodnar> wut?
[11:13] <Maxell> Upu: http://www.apritch.myby.co.uk/phgrcalc.htm and put it before your normal comment
[11:14] <Darkside> yeah i dunno

[11:14] <Upu> hmm ok let me try that
[11:15] <astrobiologist> I'm setting up my handheld and chase car app at an example frequency of 434.5Mhz. is it normally lsb or usb?

[11:16] <Darkside> yeah small shifts

[11:16] <Darkside> hrm
[11:16] <Darkside> you'd hear that
[11:16] <gonzo_> I'm still confuse at this fsk aprs. Are you just refering to demod of the baseband after the fm demod, or are you using your own real fsk on air?
[11:17] <Darkside> gonzo_: he means just sending FSK
[11:17] <Upu> oh think its fixed
[11:17] <Upu> thanks
[11:17] <Darkside> so if you dmodulate that wiht a USB receiver, and feed it into MIXW or soundmodem or whatver, it'll demodulate just like AFSK aprs
[11:17] <gonzo_> Darkside, FSK over an FM link?
[11:17] <Darkside> no
[11:18] <Darkside> raw 1200 baud FSK on 70cm

[11:18] <Upu> going away this weekend so not leaving it unattended
[11:18] <Maxell> range 5.7 km, rate 4 packets/hour
[11:19] <Maxell> is it allowed in the UK, to run unattneded digis?
[11:19] <Upu> no
[11:19] <Upu> but I ignore that
[11:19] <Upu> as the application process and requirements are full retard
[11:19] <LeoBodnar> i have used USB receiver and fed that into a TNC [12:17] <Darkside> so if you dmodulate that wiht a USB
[11:19] <Upu> G1YPQ-1 has been running for about 2 years with no NoV
[11:19] <craag> Well as long as you accept responsibility for all packets transmitted by it (including repeats), it's no different to a remote station
[11:19] <Upu> and he's a pita as his clock is out
[11:20] <Darkside> LeoBodnar: yeah i mean demodulate as in 'demodulating' the SSB signal down to baseband
[11:20] <Upu> you have to have 5 nominated people who can shut it down in 30 mins
[11:20] <Maxell> Upu: wow, ignoring stuff like that might not be such a great idea here... however I get this far too
[11:20] <Darkside> then demodulate the FSK again :-)
[11:20] <Upu> and remote access to shut it down but this doesn't count as one of the 5 people
[11:20] <Darkside> your UK APRS rules are a bit shit
[11:20] <daveake> s/APRS/radio/
[11:20] <Darkside> hah
[11:20] <gonzo_> 'demodulating' ssb is just a freq shift to baseband
[11:20] <Upu> its OFCOM and their stupid retarded don't understand it so lets make it retarded rules
[11:21] <Upu> they don't care about packet
[11:21] <Upu> not interested at all
[11:21] <Maxell> heh
[11:21] <gonzo_> you can run anattended, but needs a special addition to your licence. And as upu says, paperwork pain
[11:21] <Upu> I've spoken to a few people
[11:21] <daveake> Perhaps invent APRS-embarassing-medical-conditions-net
[11:21] <Darkside> around here we just do it >_>
[11:21] <daveake> Maybe they'd get interested then
[11:21] <Upu> and basically we just run "attended" in speech marks
[11:21] <Darkside> but we don't have the density of hams you do
[11:22] <gonzo_> they are not really that interested in what goes on in primary AR bands. As long as it stays in them
[11:22] <Upu> hence me removing TX
[11:22] <Maxell> wheheh
[11:23] <Maxell> tx might not even help here... pi1dft already is too big
[11:23] <Maxell> might invest some time on the 70cm freq
[11:23] <jonsowman> define density
[11:23] <jonsowman> ;)
[11:23] <daveake> ha my thoughts too :)
[11:23] <Upu> Anything is more densily populated than the desert that is Australia
[11:23] <Darkside> pff
[11:23] <gonzo_> in the long run I expect they will hand policeing of the AR bands over to someone like the rsgb.
[11:23] <Darkside> theres 1.5 million people living with 30km of me!
[11:24] <Upu> and thats pretty much it
[11:24] <LazyLeopard> Even Australia has a higher ham-density than some parts of (say) Africa...
[11:24] <jonsowman> or the Atlantic
[11:25] <gonzo_> that's international waters, so no licenec req?
[11:25] <gonzo_> so could all the cod be considered AR op's?

[11:42] <Darkside> pd3t: i didnt say it was a *lot* of peopl :P
[11:42] <astrobiologist> that is pretty much as I thought, but then what do individual stations do? do we repeat it to anybody else?
[11:42] <pd3t> 3.5 mil isn't either ;)
[11:42] <Upu> just transmit generally
[11:43] <pd3t> Maxell: problem is the damn fees you have to pay for the atof
[11:43] <Maxell> pd3t: yeah just crazy
[11:43] <gonzo_> 60M locally here. As the UK is so small, that counts as local
[11:44] <Maxell> for packet network.... if you do something stupid eveyone will hate you so better not break it :P
[11:44] <Maxell> "self regulating"?
[11:44] <astrobiologist> so - individual stations don't repeat the packets they receive? in which case you have to be near, and be heard by, a digipeater for your packets to get any further?
[11:45] <gonzo_> self regulation means a load of moany old men trying to play god
[11:45] <pd3t> astrobiologist: when the station is setup to digipeat it can.
[11:45] <gonzo_> and corming committies
[11:46] <pd3t> in our surrounding it's useless cos when i hear it in my car there will be enough digipeaters in the surroundings that will hear it. Besides that NL is flat as table surface ;)

[11:53] Action: Maxell should put more time in getting 70cm aprs better in The Hague
[11:54] <craag> I ran aprx as viscous digi on a pi in my car for a while - that worked well

[11:56] <astrobiologist> I emailed pocketpacket to ask if it's a digipeater
[11:56] <Maxell> pd3t: Rijswijk is closer but 70cm and not as high as pi1dft

[11:57] <pd3t> what happens when we put up a digi in rijswijk at a decent height will it cover thehague and surroundings?
[11:57] <astrobiologist> my handheld can be set to transmit on vox regardless or only when the channel is free
[11:58] <astrobiologist> presumably latter is better?

[13:23] <mikestir-work> I find the performance of my igate is way worse than you'd expect given the sort of range I get on 2m phone
[13:23] <mikestir-work> makes me wonder if 1200 baud AFSK just doesn't work that well
[13:24] <gonzo_> The traditional TNC modems are not that great
[13:24] <gonzo_> and a lot of variability in the setup of statiosn
[13:24] <craag> phone can put up with flutter, aprs can't
[13:24] <craag> then there's the fact that most people don't look at their audio drive level
[13:25] <gonzo_> the latter probably accounts for a lot of it
[13:26] <craag> yep, I've heard audio-clipped beacons
[13:26] <gonzo_> hardware TNCs had a calibration routine, that you could send separate high and loiw tones, and tweak the balance for the radio you have
[13:26] <mikestir-work> would be nice to develop something more modern

[13:28] <craag> gonzo_: That would be perfect, I've also used the eye diagram display on another rx in ax25-utils
[13:28] <astrobiologist> I suspect it is not too bad, since if I turn the volume of my ipad down much below about 75%, the vox won't open on the handheld

[14:50] <craag> I was *very* sure that wasn't the length of a mm
[14:50] <gonzo_> I work in both, as most of my machine shop is imperial
[14:50] <craag> googled 'mils' and found out...
[14:50] <craag> never come across it before
[14:51] <craag> I've heard people refer to it as thou's
[14:52] <adamgreig> thous is typical british english, mils american, as I imagine you gathered
[14:52] <adamgreig> these days I've swapped all my pcb stuff to metric really
[14:52] <adamgreig> for some reason I like my schematic editor in imperial though >_>
[14:52] <adamgreig> I want 0.1" long pins on my schematic parts, dammit!
[14:52] <adamgreig> using surface mount helps because things no longer lie so clearly on a 0.1" grid
[14:52] <gonzo_> I suppose that days of layoputs being in 10ths of inch went with DIL
[14:53] <adamgreig> should swap to calling my packages by the metric version though :P
[14:53] <gonzo_> snap
[14:53] <lz1dev> reading wikipedia about mils
[14:53] <lz1dev> such an arbitrary unit
[14:53] <adamgreig> I do enjoy the idea of splitting an inch into a power-of-ten

[14:53] <craag> lol
[14:53] <adamgreig> but I think it will be a while before I call 0603s "1608"
[14:53] <mikestir-work> it's even better that the americans went with "milli-inch"
[14:54] <mikestir-work> which is like some kind of hybrid metric/imperial name
[14:54] <adamgreig> exactly :D
[14:54] <gonzo_> I have to have a lookup chart for thou to 64ths to mm

[16:47] <Laurenceb_> yes
[16:48] <mattbrejza> whats the difference between the paths?
[16:48] <Laurenceb_> altitudes and FEA model vertex to vertex jumps
[16:48] <Laurenceb_> or something like that
[16:49] <Laurenceb_> its a crude error estimation thingy
[16:50] <Laurenceb_> yeah there is aprs over the azores, so it could catch that on the southern route

[16:54] <Laurenceb_> current track is bottom of lake Winnipeg, ok so far
[16:59] Nick change: madiz -> madist
[16:59] <Ian_> molo: on the NTX2B changing the voltage on the transmit (modulation) pin alters the frequency of the transmitter slightly, so if you were to put a suitable audio frequency on the pin you would have \
[17:00] <Ian_> pretty much a standard FM signal. The HAB community impress one of two voltages and so the transmitter radiates at one or other (sometimes more for MFSK) frequency, |
[17:01] <molo> Ian_: yes, thanks. I didn't realize domoinoex was fsk.
[17:01] <molo> but that makes a lot of sense
[17:02] <Ian_> received by an FM transmitter it would at best be clicks. A SSB transmitter allows translation of the frequency difference between the incoming instantaneous frequency and a carrier insertion oscillator to produce two (or more) distinct audio signals. Much as the BFO does for Morse.
[17:03] <Ian_> End (ain't you glad!)

[17:59] <Ian_> maxmed: if you do not feed the function properly, then it may die on you. &variable indicates passing by reference and so the variable in the call will be changed on on function exit, so if the function doesn't actually use the value give it a dummy variable that you can ignore. If the function uses it, give it a dummy variable with a suitably initiated value and ignore it on return. Is this clear?

[19:00] <DL1SGP> I have been looking for a tiny tool to put the (filtered) aprs received through equipment out as a gps signal on a com port, but such software seems to be tricky to get and time is too short to write it myself as I have other things to prepare for the hunt

[19:02] <maxmed> oops meant &i
[19:03] <OZ1SKY_5B> ok, its been sunny and about 30c here
[19:03] <molo> maxmed: in what context?
[19:04] <maxmed> if i want to use snprintf of a byte eg. hours
[19:04] <DL1SGP> we should do the launches in 5B land then Brian :)
[19:04] <molo> %d or %u depending on signed or unsigned
[19:04] <OZ1SKY_5B> DL1SGP hehe yeah, had hoped for a flight pass here, but didnt happen.

[19:07] <DL1SGP> Guten Abend Kevin
[19:07] <jededu> Is it possible to do CRC16_CCITT checksum in basic ?
[19:07] <molo> jededu: why wouldn't it be?
[19:08] <LeoBodnar> yep Lunar_Lander what's up?
[19:09] <jededu> We are trying to impliment it with no success a few have tried and failed
[19:09] <mattbrejza> why wouldnt it be possible? :/
[19:10] <LeoBodnar> it can be done even in excel [20:07] <jededu> Is it possible to do CRC16_CCITT checksum in basic ?
[19:11] <LeoBodnar> i am sure even PICAXE can do it
[19:12] <nigelvh> Summary: You can do it in assembly, so every other language written is possible.
[19:13] <jededu> mmmm thats all thats stopping us if its possible i will persevere

[19:15] <arko> wait, crc16 doesnt have a lookup table does it?
[19:15] <arko> i thought it was just bitwise operators and shifts and things
[19:15] <jededu> I think i have seen one maybee im wrong
[19:17] <LeoBodnar> you can do CRC with lookup tabe or without

[19:37] <maxmed> As advised I have re-written my balloon tracking code from scratch but obviously it is still heavily based on the origonal code. The new code is hopefully as simple as possible, it compiles fine and is apparently error free on CPP check. Please could you check if there is anything you would change before I add it to the "radio part"? Code is here: https://github.com/Max-Med/New_HAB_Code/commit/96d767f737befcb9c06cb9f3a16640a184
[19:39] Laurenceb (~Laurence@host86-167-154-80.range86-167.btcentralplus.com) joined #highaltitude.
[19:40] <mikestir> I guess you'll need to use %02u rather than %u to print the time parts, because you want it to add leading zeroes
[19:40] <molo> maxmed: you should check the fix age before you do anything else
[19:41] <mikestir> yes, although that's only because you are wasting time calculating things you then don't use
[19:41] <molo> can also have power implications..
[19:42] <mikestir> sure
[19:42] <molo> which reminds me.. does serial.available() sleep? or fail fast?
[19:42] <molo> er, not sleep
[19:42] <molo> block
[19:42] Action: molo didn't get enough sleep last night
[19:43] S_Mark (~S_Mark@host86-143-148-254.range86-143.btcentralplus.com) joined #highaltitude.
[19:43] <mikestir> I don't suppose power consumption is a big consideration here (yet)
[19:43] <daveake> serial.available just checks the rx buffer
[19:43] <mikestir> maxmed: one general comment is that you should really declare your variables within the function where they are used
[19:43] <molo> it depends on the intended use
[19:43] <daveake> so it returns immediately
[19:44] <molo> daveake: so the loop will only run once under normal conditions?
[19:45] <daveake> 1 sec I'll look at the code
[19:45] <mikestir> under idle conditions loop() will just fall straight through and be immediately re-invoked
[19:45] <mikestir> it is a busy wait
[19:45] <daveake> In loop() you can do if (serial.avail...) or while (....)
[19:46] <daveake> If there's nothing else in loop() then both have the same result
[19:46] <molo> right, so in a normal setup you only will get one update per second or so and the serial.available() will fail and the loop will exit.
[19:46] <mikestir> daveake: is arduino main just setup(); while (1) { loop(); } ?
[19:46] <daveake> aiui yes
[19:47] <maxmed> mikestir : ok I'll change the format identifiers accordingly, molo: so I could just move the "if (fix_age == TinyGPS::GPS_INVALID_AGE){ " to just after where it gets the time (before the lat and lon) ? mikestir: when you say define within the function could you give an example, I dont fully understand.
[19:47] <daveake> I do the while() thing
[19:47] <daveake> feels better
[19:48] <molo> mikestir: oh, so this is already within an event loop.. nevermind then. still needs a sleep() or yeild() or golowpower() or something in there.
[19:48] <mikestir> maxmed: where you declare all your variables (lines 2 to 7), these are described as having "global scope", because you can access them from any function in the program. As you progress in programming you will find that global scope is something to be avoided
[19:49] <mikestir> because all those variables are only used in loop() you can move the declarations and insert them after line 14
[19:49] <maxmed> ok, so i should define them within the void loop() ?
[19:49] <mikestir> yes
[19:50] <molo> maxmed: right after the get_datetime(), do something like: if (fix_age == TinyGPS::GPS_INVALID_AGE) { snprintf([....]); continue; }
[19:50] Prometheas (~marios@78-67-84.adsl.cyta.gr) joined #highaltitude.
[19:50] <molo> maxmed: then no need to have the else block
[19:51] <mikestir> molo: it's arduino so all bets are off, but of course if the serial driver is interrupt driven then you could just put a sleep call in at the bottom of loop()
[19:52] <molo> mikestir: yes, that could work, but I don't know the platform that well to say for certain.

[19:55] <maxmed> molo: Do I not need the else{..} after the if{..} statement even if I move it to prevent it running the rest of the code if there is no gps lock?
[19:55] <molo> maxmed: that is what the continue; statement is for
[19:55] <molo> it starts the loop over
[19:55] <molo> the while() loop
[19:55] <daveake> No need to bet; just read the documentation. Arduino does use serial interrupts
[19:56] <mikestir> you could go to idle mode then. no lower though
[19:57] <maxmed> molo: would it then not skip the "radio stuff" so the snprintf datastring would not be transmitted? I liked the idea of being to receive a message saying there was no gps fix so i knew it was working.
[19:58] <molo> maxmed: ah, sorry, yes, if that is your intent.
[19:59] <maxmed> ok no worries, at least it shows this time I understand my own code! yay!
[19:59] <molo> :)
[20:00] <mfa298> if there's no gps fix what most people will do is retransmit the last good data and have a flag that indicates if the fix is good (set sats=0 if no fix and only treat sats>=4 as having a fix)
[20:00] <mikestir> so the policy to keep all complete tracker code secret does work :)

[20:03] <maxmed> I think my code will continue transmitting the same data if it loses a fix? It should only print the error message at the start before it has got a fix.
