[07:46] <jcoxon> mikestir, don't want to make it too easy
[07:46] <mikestir> it does mightymik
[07:47] <mikestir> it's 100,8n2 360 ish shift, maybe a bit wider now
[07:47] <mikestir> probably need to widen the filter a bit as well

[09:27] <gonzo_> I get habaxe1 at 434.40425 ctr of data
[09:28] <gonzo_> the warm up drift on tx is preetty bad. Have to use wide filters or retune every packet
[09:28] <mikestir> gonzo_: that sounds about right. it's drifting fast
[09:28] <gonzo_> (wide fldigi filters I mean)
[09:28] <mikestir> just seeing it here

[09:29] <gonzo_> the prob with wide filters, it helps the afc, but is going to kill the snr

[09:38] <mikestir> oh so the payload doc is wrong
[09:38] <mikestir> it's 100 baud
[09:38] <mikestir> that would explain why it wasn't decoding at all
[09:38] <gonzo_> yes 100bd
[09:39] <gonzo_> the pauses between tx are a pain
[09:40] <mikestir> yeah the drift is quite extreme. possibly trying to do discontinuous with an rfm22 is a step too far
[09:40] <gonzo_> and not even enoungh time between start of tx and the data, so by the time you have manually reset the fldigi decodewindow, you have missed the first ew chrs
[09:41] <gonzo_> few (ironic!)
[09:41] <craag> wow just tuned into the habaxe on the websdr and the drift is very audible!
[09:42] <gonzo_> yep really bad to try and rx
[09:42] <mikestir> ha. that one was about 300 hz higher than the last tx
[09:42] <gonzo_> wide filters and afc off is about the only way.

[14:44] <jededu> What are the licencing requirements for APRS
[14:45] <mfa298> jededu: for arps in a useful way you need an amateur radio license.
[14:45] <nats`> jededu you need to be a HAM I think
[14:45] <jededu> Which one is adequate Inermediate ?
[14:45] <Upu> you can't use it airborne in the UK
[14:45] <mfa298> no allowed airborne in the UK so you need a Full license to be able to use it in countries that are part of CEPT (Europe, USA and a few others)
[14:46] <Upu> you need full to use it reciprocal
[14:46] <jededu> Yes I have read all about it :)
[14:46] <jededu> Better get started then :)
[14:48] <mfa298> in theory you should be checking the rules for all the countries you fly over as you have to be abiding by their rules, and with the UK license you can use it airborne over international water (but you could look at getting a US license which might allow the use over international waters)
[14:49] <jededu> Ill investigate my local clubs tomorrow

[18:44] <Upu> tx now
[18:46] <amell> the frequency on habaxe1 drops about 150hz in the course of a single string?!?

[18:51] <Upu> yes it was 5 mins ago
[18:51] <Upu> but far too weak for me to RX
[18:51] <LeoBodnar> no but you have to predict where it's going to start

[20:16] <Lunar_Lander> unfortunately the wind was a bit weaker than planned and that was why the timers released the cameras over Poland as you said

[21:46] <craag> that was a year or so ago - they don't seem to have improved it
[21:46] <kf7fer> oh. guess I missed it. It has a nice case though
[21:47] <craag> I think it was on their twitter or something
[21:47] <craag> Well those GSM trackers are about 50% reliable, so using 2 means you get 100% right?
[21:47] <craag> :P

[21:49] <kf7fer> Ok I do see http://sentintospace.com/our_story/prototypes/
[21:49] <kf7fer> craag: maybe use two different wireless carriers as well?
[21:50] <craag> Yeah probably
[21:50] <craag> Although there are cheap any-net sims easily availible

[21:51] <kf7fer> that was a bit tongue in cheek since I suspect that most of the "3rd party carriers" - at least in the US - probably all share the same network
[21:52] <craag> Ah that hasn't happened over here yet
[21:52] <craag> It's on it's way - but currently most installations are single-operator.

[23:28] <nigelvh> Has anyone run a MAX7 or 8 with the voltage supply sourced by an atmega digital out pin?
[23:28] <nigelvh> Seems like the current requirements fit.
[23:33] <qyx_> huh
[23:33] <qyx_> you would like to use a transistor
[23:33] <qyx_> p-mosfet ideally
[23:33] <nigelvh> I'm using a transistor now, but if I can save the board space, that would be shiny.
[23:34] <qyx_> it is like 3mm
[23:34] <nigelvh> I'm aware, but every 3mm adds up
[23:35] Nick change: Flerb -> ChrisHansen
[23:35] <qyx_> i wouldn't do that, avr outputs can have required current capability but there will be some voltage drop
[23:36] <nigelvh> Yes, and that's where the concern comes in.
[23:36] <nigelvh> Figured I'd ask if someone had actually done so.

[23:43] <SpeedEvil> 747 wave https://www.youtube.com/watch?v=bnBr3enzW1I
[23:43] <SpeedEvil> got spare pins?
[23:44] <SpeedEvil> One is probably a bad idea
[23:44] <SpeedEvil> 8 - maybe not quite so bad an idea
[23:45] <kf7fer> nigelvh: I used to just use a PNP to switch power off and on for the MAX6/7. Kinda old school I guess but it worked
[23:45] <nigelvh> Yeah, that's what I've got on the current revision of my board.
[23:45] <nigelvh> Just working on a new revision trying for smaller/ligher/fewer parts/etc.
[23:45] <kf7fer> Anymore I don't bother... I ran low on I/O pins and it looks like the whole board draws 36mA before a fix and 13mA afterwards (until I transmit ;-) )
[23:46] <kf7fer> I'd be worried about drawing more than 10mA from an AVR pin
[23:46] <nigelvh> AVR pins are rated to 40mA
[23:46] <kf7fer> but isn't there a total limit as well that is fairly low?
[23:47] <nigelvh> And my current revision between transmissions and turning the GPS off will drop down to about 1mA
[23:47] <kf7fer> for all the pins at once?
[23:47] jaymzx_away (~jaymzx@192.210.149.170) left irc: Ping timeout: 272 seconds
[23:47] <SpeedEvil> kf7fer: yes
[23:48] <nigelvh> 200mA
[23:48] <SpeedEvil> kf7fer: but - the issue isn't only the max per-pin current, but also voltage dro
[23:48] <SpeedEvil> 8 pins in parallel willl have much lower voltage drop
[23:49] <kf7fer> of course don't forget... " Exposure to absolute maximum rating conditions for extended periods may affect device reliability. "
[23:49] <kf7fer> which is 40mA
[23:49] <nigelvh> Yes

[23:51] <qyx_> you can combine multiple pins.. but then you have to be sure you are turning them on/off all at once
[23:51] <nigelvh> Yeah

[23:52] <SpeedEvil> kf7fer: 40mA per pin though
[23:52] <nigelvh> Which would be plenty for the 7C or Q
[23:53] <SpeedEvil> - up to the total limit
[23:53] <SpeedEvil> 8*10 should be fine say
[23:55] <kf7fer> ok... just looking at the datasheet. Sorry, looks ok. But what about "max supply current" being 67mA?
[23:56] <nigelvh> Yeah, it shouldn't *normally* draw that much, but could. Which would put it outside the AVR's range for one pin.

[23:58] <kf7fer> and qyx_: How ugly is that? I know it works but just seems... like a total hack
[23:58] <qyx_> i would understand space constraints if you used qfn/wlcsp or similar package
[23:58] <kf7fer> I'd be afraid I'd make a typo and blow the hardware ;-)
[23:58] <qyx_> but one sot23 fet is not much if you are using pdip/tqfp version of avr
[23:58] <theRealSIbot> In real units: 23 ft = 7.01 m
[23:58] <nigelvh> Well, if you're manipulating ports, it's pretty easy to switch them at once. But you' can't use the Arduino digitalWrite options.
