[00:36] <Maxell> And then select the .14n file
[00:37] <Maxell> However SondeMonitor needs a good quality signal :)
[00:39] <jarod> ya its gone now
[00:39] <jarod> so they changed balloon data?
[00:43] <Maxell> That is the most recent information so fare I know
[00:53] <jarod> cool
[00:56] <jarod> Maxell it says enter a number?
[00:57] <Maxell> Luanch site?
[00:57] <Maxell> Launch*
[00:57] <jarod> yes
[00:57] <jarod> ah no N and E

[00:58] <jarod> i guess no way to see if the proper signal is received?
[00:59] <Maxell> 52.1,5.18 then?
[00:59] <jarod> ya did that and good
[00:59] <jarod> i hope
[01:00] <jarod> is it connect 403.9 signal now has tow site carriers?
[01:00] <Maxell> fm
[01:00] <Maxell> get fm and make it is wide enough 15 khz or something
[01:01] <Maxell> strong signal might be wider

[13:27] <Flerb> Anyone know how I could decode the time signal on Radio 4's LW station?
[13:30] <mikestir> yes
[13:31] <mikestir> i've done it in software before
[13:31] <mikestir> it's probably easier to use msf though unless you have some specific reason for using r4?
[13:32] <Flerb> mikestir, well
[13:32] <Flerb> Radio doesn't go down to 60khz
[13:33] <mikestir> can you do ssb on r4? it's phase modulated so you need to downconvert the carrier to an audio frequency if you want to use a pc soundcard
[13:33] <mikestir> if you can tune usb there then that would do
[13:34] <mikestir> I'll need to dig out the software, which I may not have because it was a work thing. The necessary documentation is public though and it wasn't very hard
[13:35] <Flerb> mikestir, yeah.

[13:47] <mattbrejza> does a 192ksps still have a ~20kHz input filter?
[13:47] Flerb (~Willdude1@unaffiliated/willdude123) left irc: Ping timeout: 260 seconds
[13:48] <mikestir> don't know, might depend on the codec. I guess probably not
[13:49] <mikestir> I assume the funcube dongle uses a normal audio codec chip so that would suggest not
[13:49] martijn__ (~martijn@moeling.xs4all.nl) joined #highaltitude.
[13:50] <mattbrejza> i was more thinking of any input filtering before the codec
[13:50] <mattbrejza> although first you need to see if any decoders exist

[14:04] <chrisstubbs> is this on a 100g pawan?
[14:04] <amell> y
[14:06] <jededu> amell are you launching
[14:06] <amell> yes
[14:06] <jededu> what time
[14:06] <amell> 6pm ish - probably not before. want it to blow south
[14:07] <chrisstubbs> Got a prediction?

[14:08] <jededu> Me too
[14:09] <jededu> amell at 5.5g of free lift on a 100g SLEET floated
[14:09] <amell> i will be surprised to float. but hey
[14:10] <chrisstubbs> 5g of free lift will not give you 5m/s ascent like on that prediction
[14:10] <amell> this payload will be on an 12 chute, so may take some time to descend.
[14:11] <amell> chrisstubbs: http://predict.habhub.org/#!/uuid=89a5590faec48eb37712a75e262ecc955d08aa08

[14:11] <chrisstubbs> Cool :)
[14:11] <chrisstubbs> Will be interesting to see how far you can get it :P
[14:12] <amell> bit of a poke in the dark, but see what happens.
[14:12] <chrisstubbs> If its close I will see if I can recover it
[14:12] <jededu> How heavy is your payload
[14:12] <amell> its chrisstubbs payload. 41g.
[14:12] <jededu> ahh
[14:13] <amell> chrisstubbs, i will put the chute on the bottom of the payload, not the top, and tuck it in a bit.
[14:14] <amell> the idea being the payload will invert as it descends.
[14:14] <amell> its a chinese model rocket parachute i have (lost the actual rocket in corn&)
[14:15] <chrisstubbs> I'd tie it on to the top so the payload hags the correct way up. Otherwise it might be hard to track :P
[14:15] <amell> i was assured turnnig it over wouldnt make a difference.
[14:15] <amell> is that the case?
[14:16] Action: amell blames someone in here, but cant remember who.
[14:16] <chrisstubbs> Hmm that may well be the case, im no expert but I would assume having the antenna above the radials would send most of the RF power into the sky
[14:17] <jededu> Thats what I have found when testing
[14:17] <amell> you have four ground planes, and an antenna.
[14:17] <jededu> Yes
[14:17] <amell> i had to figure it out, as when payload was originally recovered, it was all mashed into a ball...
[14:18] <chrisstubbs> Yeah, and ideally the antenna wants to be facing down
[14:18] <chrisstubbs> heh that tends to happen
[14:18] <amell> looks like the antenna is the one thats soldered to its own pad.
[14:18] <chrisstubbs> Yeah there should be 3 pads one side and 2 the other
[14:18] <chrisstubbs> its the middle of the 3
[14:18] <amell> yup
[14:18] <Geoff-G8DHE-M> Indeed radiation angle is about 45 degrees between radials and active element.
[14:19] <amell> ok. on top it is.
[14:19] <amell> will poke a hole through the chute
[14:19] jcoxon (~jcoxon@ joined #highaltitude.
[14:24] <chrisstubbs> You will be looking more at around 100g free lift for 3m/s ascent amell
[14:24] <chrisstubbs> I tend to just empty the helium canister into the balloon
[14:24] <amell> how much lift will that give?
[14:24] <amell> want to keep it slow.
[14:25] <chrisstubbs> Cant remember off the top of my head, let me have a look
[14:25] <cm13g09> afternoon all
[14:25] <amell> 0.43m3 of He
[14:27] <amell> gives approx 4.5m/s ascent rate
[14:28] <amell> 0.16m3 of He gives 2m/s
[14:29] <chrisstubbs> Yeah I got about 4.12m/s irl from 0.43m3
[14:29] <amell> 0.20m3 gives 107g neck lift and 3.22
[14:29] <amell> m/s
[14:29] RA9OEK (6dae3434@gateway/web/freenode/ip. joined #highaltitude.
[14:29] <jededu> how heavy is the complete payload with chute ect
[14:29] <amell> 42g
[14:29] <chrisstubbs> I use a filler valve so not quite all aln the helium will have gone in
[14:30] <RA9OEK> DL7AD hi there
[14:30] <chrisstubbs> Yep 60-70g of free lift should do it then
[14:30] <amell> 5g free lift will give 1.5m/s ascent rate - 0.15m3 He
[14:31] <amell> do you mind if it actually floats? I dont think it will but theres a danger.
[14:31] <chrisstubbs> Not at all, do what you like with it
[14:31] <amell> to get to chelmsford, it will need to be v slow ascent.
[14:33] <amell> so well go for c. 2- 2.5m/s ascent to hopefully hit chelmsford/braintree. that means i need neck lift of 81g
[14:33] <amell> = free lift of 40g or so.
[14:34] Action: amell goes to find 40g of blue tack

[17:58] <Lunar_Lander> and where is Raspberry Pi C?

[18:17] <astrobiologist> evening all
[18:18] <Steve_G0TDJ> Hi
[18:18] <astrobiologist> I got some SMA crimp connectors in the post but the diameters of the crimps seem really tiny
[18:18] <astrobiologist> way too small to crimp RG58
[18:19] <astrobiologist> is there a much thinner type of coax out there that people often use with smaller connectors like SMAs?
[18:19] <qyx_> rg174?
[18:19] <qyx_> its 2.8mm outter diameter
[18:19] <pd3t> Herman-PB0AHX: we aren't going to steal my packets are we....
[18:20] <astrobiologist> qyx is rg174 any good? is it still 50ohm?
[18:20] <NigeyS> astrobiologist it's 50ohm yup
[18:20] <qyx_> it is 50ohm, often used to make pigtails, short interconnects or measurement cables

[19:50] <myier> I'm so angry against sleep.
[19:51] <F1VJQ> myier yes, I suppose you would need to be very keen! It was tracked from Corsica and via APRS
[19:51] <daveake> Is EDUHAB supposed to be cutting down? It says "cutdown-1" but is still ascending (slowly)
[19:51] <amell> cheapo about 480 shift.
[19:51] <myier> yes
[19:51] <Steve_G0TDJ> amell: It's a shame the prediction isn

[19:52] <amell> how the f. does 60g free lift make for 1.4m/s ascent?
[19:52] <chrisstubbs> Did you add lots of tape or anything?
[19:52] <chrisstubbs> Cable ties etc all add up
[19:53] <amell> weighed the cable ties and tape. about 3g
[19:53] <amell> and it was giving me a reasonable tug just prior to letting go.

[19:57] <fsphil> what's the otherone?
[19:57] <Steve_G0TDJ> EDUHAB and CHEAPO
[19:57] <amell> chrisstubbs: by the way, you reset the RFM every 50 sentences. it cuts out briefly and gives me red.
[19:58] <amell> just cut out on sentence 250 :)

[19:59] <Geoff-G8DHE> Oh nyes turned around
[20:00] <amell> the predict is wrong

[20:10] <Reb-SM0ULC> this internetthing is kind of cool. sitting around in a cabin in the countryside some 1700+ km away tracking via websdr via a 3g-modem, just works.. :)
[20:11] <db_g6gzh> last time it flew I did a quick hack s/sequence_id/count/g but it still failed as there were 2 payloads on that flight
[20:12] <amell> what descent rate does snus use for its predicted landing site?
[20:12] <Geoff-G8DHE> Its so strong with me I don't need the beams on it anyway there tracking CHEAPO so about 40 degrees off from EDUHAB
[20:13] <fsphil> it varies amell, it can be changed to suit the flight
[20:13] <fsphil> after burst it uses the actual descent rate
[20:13] <db_g6gzh> I mean sentence_id and I just did it again with success this time
[20:13] <amell> where do you set the descent rate rate? is it in flight doc?
[20:13] <fsphil> nah done by an admin
[20:14] <fsphil> it should be something in the flight doc
[20:14] <fsphil> would be a more sensible place to have it
[20:14] <chrisstubbs> I'm still surprised the box on snus isnt auto populated by the details in active flight docs
[20:14] <amell> cheapo has an 18 chute, so it will be interesting to see what the descent rate is :)

[20:43] <Upu> going to hazard a guess cheapo is an RFM22B

[20:43] <fsphil> eduhab's signal just faded quite a bit here

[20:45] <fsphil> F1VJQ: maybe the local weather patterns mean long distance propagation on vhf is rarer? I don't know
[20:46] <amell> Upu: why do you need to know my position?
[20:47] <chrisstubbs> Upu I liked being able to click on points in the flight and see the info from that sentance, but I think all those datapoints is what killed the old one
[20:47] <Upu> personally I don't
[20:47] <Upu> but it gives information based on you location as it can be used mobile on a GPS equipped device
[20:47] <amell> ok
[20:48] <Upu> yeah I know lz1dev is working on possibly just displaying the last hour like APRS.fi
[20:48] <F1VJQ> fsphil normal tropo from here with 12 ele at 10m agl is about 700km- 800km into southern UK, Belgium, and near parts of Holland.. for decently sited stations
[20:48] <fsphil> ah, I'm using a colinear :)
[20:49] <F1VJQ> fsphil with extra assist from lifts have heard Madeira beacon for days at a time, and worked Sweden and Denmark on SSB
[20:49] <amell> how do i stop the dl-fldigi rtty red bars from jumping away?
[20:49] <Geoff-G8DHE> Keep the link to Google Earth and for the whole data to be sent out in KML format please!
[20:49] <amell> theres a button somewhere...
[20:49] <fsphil> no reason the data on points can't be fetched on demand

[20:49] <lz1dev> yep
[20:49] <myier> it seems quite nice, with the two rates in bonus

[20:50] <amell> for some reason my rtty red bars keep jumping up. any idea why?
[20:51] <Geoff-G8DHE> amell right click the RTTY mode left corner and set the Recieve Filter Bandwidth wider its to narrow for drifting Tx

[20:51] <Upu> cut down didn't work ?
[20:51] <amell> dont think thats the issue, the frequency keeps jumping up.
[20:51] <F1VJQ> qyx I was getting freezes recently on FF with philcrump
[20:52] <Upu> Geoff-G8DHE log it here if you get mo https://github.com/rossengeorgiev/habitat-mobile-tracker/issues

[20:53] <Upu> just not charging them
[20:54] <jededu_> It had a lot of gas in it
[20:54] <Maxell> Nice long -1.111111
[20:54] <LazyLeopard> Upu: Looks good. A cut-off "start from here" time (per payload?) would be nice. Slightly miss the green HAB-to-tracker lines (and associated pop-ups) but suspect they might be at least a part of what makes the current tracker a mite sluggish...

[21:41] <Laurenceb__> the dipole is hungry
[21:41] <myier> the cable between the antenna and the receiver needs to have a balun or else it acts as part of the antenna too, but does it change its length, as in "quarter-wave dipole", with a longer cable it's no longer a quarter wave or what?

[21:46] <myier> or do you use other kinds or antennas on balloons

[22:22] <chrisstubbs> heh
[22:22] <amell> or maybe its in that in-between zone.

[22:23] <amell> next time i will put the whole bloody tank in!
[22:23] <db_g6gzh> no. it's off 8-)

[22:24] <amell> cheapo appears to be confused about where its going
[22:24] <mikestir> north doesn't look good. you need to get away from the sea for the descent

[22:24] <chrisstubbs> going for a full loop-de-loop

[22:43] <fsphil> call that a descent rate?

[22:43] <amell> fsphil: 18 chute ftw!
[22:43] <fsphil> it might not reach the ground
[22:43] <amell> is it spinning?
[22:43] <F1VJQ> Sinclair made floppy loop tapes too!
[22:43] <amell> i reefed the chute by wrapping it round the payload

[22:44] <daveake> Upu's one with the latex-a-chute was even slower

[22:44] <F1VJQ> fsphil I dunno! I managed to read some of what I wrote about 80% of the time ROFL
[22:44] <fsphil> hah
[22:44] <fsphil> and it didn't chew up the tape?
[22:44] <amell> predict shows cheapo is headed out to sea. oh dear
[22:45] <F1VJQ> fsphil well sometimes!!
[22:45] <mikestir> deal or no deal
[22:45] <mikestir> that is the question
[22:45] <bertrik> CHEAPO is drifting quite a bit
[22:46] <F1VJQ> there was a HAB headed for the coast last year... went over near Felixstowe Ferry, and turned ...landed 500m offshore!
[22:46] <amell> can you tell if it is spinning?
[22:46] <Lunar_Champion> I think the sound of the RTTY tells that or so
[22:46] <fsphil> the sound of the signal sometimes tells
[22:46] <F1VJQ> fst QSB usually means spin
[22:46] <amell> is it?
[22:47] <amell> i must admit i didnt expect the descent rate to be that low at this altitude.
[22:47] <F1VJQ> fst = fast fading
[22:47] <F1VJQ> well it seems slow... maybe trailing the entrails!

[22:50] <amell> payload is only 42g
[22:50] <Maxell> ah
[22:51] <daveake> 18" is way too large for 42g

[22:51] <Maxell> inb4 payload taking a swim
[22:51] <amell> daveake: yes, but it was rubbish i didnt want.
[22:52] <amell> its an estes rocket chute, i lost the rocket so had a chinese binliner spare.

[22:52] <amell> no. chrisstubbs might if it actually lands close to him. looks like it wont
[22:52] <daveake> Just cut a larger bleed hole

[22:55] <amell> seems to be holding steady at -4.2 -5 m/s

[23:07] <myier> do you easily find helium in UK? how much does it generally cost for a 800g latex balloon?
