[06:01] <ibanezmatt13> Good Morning :)
[06:03] <ibanezmatt13> I have had a slight change of thought. For my first flight, to save a little money, I'm going to use a Raspberry Pi Model B because I already have one of those. I'm not using a webcam or anything though. So I guess it still needs 5v power, just a different current.
[06:05] <ibanezmatt13> In fact, I've changed my mind again. I'll stick with getting a Model A. Don't want to risk a power failure...
[06:05] <eroomde> live brainstorming
[06:06] <ibanezmatt13> indeed :)
[06:06] <ibanezmatt13> Do you think I should just use my Model B, or get a Model A?
[06:07] <eroomde> almost always, the difficult thing in a project is development
[06:07] <eroomde> and human interfacing
[06:07] <eroomde> i would do whatever minimises the complexity of getting it developed and flight ready
[06:07] <eroomde> that might mean developing the software on the B and then portingit to an A once it's all well tested
[06:08] <ibanezmatt13> The two models are pretty much identical apart from power usage. But that is a good idea, I'll worry about that nearer the time, thanks :)
[06:09] <ibanezmatt13> I asked my Dad last night and he said that in two weeks (when the last of my GCSEs are over) we can drive up to the HAB supplies store and pick up the radio transmitter and the GPS. I'll be able to speak to Anthony also :)
[06:10] <eroomde> he'll sort you out
[06:12] <Randomskk> hey eroomde if you had to guess what kind of current a modern smartphone drew while off
[06:12] <Randomskk> what kind of figure do you reckon?
[06:12] <Randomskk> because I think I've found a reason my phone's battery life is quite so abysmal...
[06:12] <eroomde> mA?
[06:13] <Randomskk> not just screen off but whole phone shut down
[06:13] <eroomde> oh - 'off' properly?
[06:13] <eroomde> hmm
[06:13] <eroomde> uA
[06:13] <Randomskk> right
[06:13] <Randomskk> so like, less than 0.3A
[06:13] <Randomskk> and yet
[06:13] <eroomde> jeeeesus
[06:13] <Randomskk> yea!
[06:13] <Randomskk> it's a 1.2W heater
[06:13] <Randomskk> no wonder it was eating up battery
[06:13] <eroomde> something might be a bit wrong there
[06:13] <Randomskk> it's been dodgy for months
[06:13] <Randomskk> just now got around to hooking it up to my bench psu and an ammeter
[06:14] <Randomskk> with everything turned on and the screen off, it's also 0.3A, but bursts to 0.8A or so
[06:14] <Randomskk> with the screen on it's like 0.7A bursting to 1.1A or so
[06:14] <Randomskk> wolfram alpha helpfully tells me that 0.3A*4V is "7.5x typical smartphone power consumption in sleep mode"
[06:15] <eroomde> nice
[06:16] <Randomskk> I was really hoping for a new phone at google io so I could just buy that and put this sorry mess behind me
[06:16] <eroomde> at google?
[06:16] <eroomde> oh googlio io

[06:16] <Randomskk> but alas, they just announced an S4 with stock android, which is like £500 or so
[06:17] <Randomskk> and the nexus 4 has been out for positively months :P
[06:17] <eroomde> so last quarter
[06:19] <Randomskk> right.
[06:19] <Randomskk> what's a person to do
[06:19] <Randomskk> could send this one in for a repair I guess
[06:19] <Randomskk> but that means weeks without a (smart)phone which is a bit annoying
[06:20] <eroomde> probably harder and less worth repairing than test equipment
[06:20] <Randomskk> yes I don't like to imagine trying to take it apart
[06:21] <Randomskk> hmm found someone else's numbers for my phone, they have 0.04W in sleep mode
[06:21] <eroomde> right
[06:21] <eroomde> so some shit has definitely gone down
[06:21] <Randomskk> yes
[06:21] <Randomskk> I wonder if there's like, a short
[06:21] <eroomde> could be s/w
[06:21] <Randomskk> the phone's off!
[06:21] <eroomde> as it's all soft on and off anyway
[06:21] <Randomskk> true
[06:21] <eroomde> could be a major subsystem power fet has failed open
[06:22] <eroomde> save up for standards btw
[06:22] <eroomde> they are worth it
[06:22] <Randomskk> so I hear
[06:22] <eroomde> a voltage standard, a current standard, a handfull of 0.01% resistors
[06:22] <Randomskk> nice to be sure about things
[06:23] <eroomde> you can get boxes for all of these, eg a 0.02% voltage with 5 0-9 clicky wheels and a decade selector
[06:23] <eroomde> so you can do 0-9.9999uC to 9.9999V
[06:23] <eroomde> uV*
[06:23] <eroomde> used it to reclaibrate the fluke meter yesterday
[06:24] <Randomskk> nice
[06:24] <eroomde> likewise a current source from the same people
[06:24] <eroomde> like you say, it's nice to be sure
[06:24] <eroomde> also used it for calibrating ADC cards

[09:11] <ibanezmatt13> Good Morning :)
[09:12] <Randomskk> morning
[09:12] <ibanezmatt13> I've got a free lesson in school :)
[09:12] <Randomskk> I remember frees fondly :P
[09:13] <ibanezmatt13> I was wondering, I didn't realise that Anthony (UpuWork, I believe) is based in West Yorkshire. That's around the location where we plan to launch our HAB.
[09:18] <ibanezmatt13> Perhaps in the Summer, if UpuWork is flying a HAB, we could use the same balloon? That way, I'll be able to have a backup and I'll probably learn quite a lot.
[09:19] lz1dev (~rgp@46.47.80.192) joined #highaltitude.
[09:19] <Randomskk> I imagine he'll be around soon
[09:20] <ibanezmatt13> That's good, I'll hang around. Should be able to stay on til 11
[09:21] <ibanezmatt13> Regarding the Lithium L92 batteries, would it be a good idea to insulate them in some way. I want them to operate as efficiently as possible.
[09:21] <eroomde> they'll probbly keep themselves warm enough if powering a pi
[09:21] <costyn> ibanezmatt13: they do fine at cold temperatures
[09:22] <costyn> ibanezmatt13: no need to insulate them extra if they're inside the payload box
[09:22] <costyn> and it's going to get cold in any case
[09:22] <ibanezmatt13> that's good. So does the inside of the payload box get quite warm?
[09:22] <costyn> well
[09:23] <costyn> considering the outside is -55 and inside is only -10 I'd say that's kinda warm
[09:23] <ibanezmatt13> that is kinda warm :)
[09:23] <costyn> but it really does depend a lot on your payload box and how well you've closed off any seams and camera openings
[09:23] <ibanezmatt13> Where can I get the box from. Do I have to mould it my self?
[09:23] <costyn> yes
[09:24] <costyn> get some 2.5 - 3cm thick XPS foam
[09:24] <costyn> and cut it into the required panels and glue them together
[09:24] <ibanezmatt13> any particular glue?
[09:24] <costyn> Uhu Por is recommended
[09:24] <ibanezmatt13> ok :)
[09:25] <eroomde> some glues and spay paints eat polystyrene
[09:25] <eroomde> be warned
[09:25] <ibanezmatt13> My Dad works in the cardboard industry (i know that sounds really bad) but he says it will look good for him if he could make a cardboard payload box. He says it can withstand temperatures of -50 and he can make it very strong and waterproof. I said it was a bad idea, but still
[09:26] <costyn> ibanezmatt13: might work just fine
[09:26] <costyn> ibanezmatt13: I'd think cardboard might be heavier than foam, but we won't know until *you* try it :)
[09:26] <ibanezmatt13> i think i'll try it properly first, and then I'll try that on another flight.
[09:27] <costyn> ibanezmatt13: but if you can get your dad to make a payloadbox then that's one less thing less to worry about :)
[09:27] <ibanezmatt13> So if it plummets into the North Sea, would it float with the foam, is it waterproof?
[09:27] <costyn> the foam is, your electronics arent
[09:27] <costyn> but if it lands in the sea, chances of recovery are slim
[09:28] <costyn> unless you plan on a water landing and have a boat standing by
[09:28] <ibanezmatt13> I'll try and get it right first time
[09:28] <costyn> ibanezmatt13: the predictor is quite reliable so you should know beforehand where it'll head
[09:28] <ibanezmatt13> that's good.

[09:29] <Brace> costyn: about the predictor, I assume that more than a day ahead it's quite inaccurate?
[09:30] <ibanezmatt13> I'd check it the night before I think
[09:30] <x-f> a week ahead it is quite inaccurate, three days and less ahead it is fairly precise
[09:31] <Brace> ibanezmatt13: give him a spec (i.e. specific dimensions, able to insulate, can't weigh more than X, etc etc) and tell him to have at it
[09:31] <Brace> that's how I work with my mate who's handling the camera side of things
[09:31] <costyn> Brace: 7 days
[09:31] <ibanezmatt13> I'll get all the parts together first and then I'll do that :)
[09:31] <costyn> Brace: and what x-f said :)
[09:31] <Brace> okies, cool
[09:32] <Brace> that's roughly what I'd thought
[09:32] <ibanezmatt13> It won't weigh more than 900g anyway, I should hope
[09:32] <Brace> bit like the weather forecast, ok a few days in advance, crap anylonger than that
[09:32] <costyn> Brace: well winds at higher altitudes change less often I believe

[09:34] <Brace> costyn: ahhh ok
[09:35] <Brace> yeah, I suppose that with prevailing winds etc, it's got to be fairly accurate, makes sense
[09:39] <ibanezmatt13> Can you launch HABs on a windy day?
[09:40] <Brace> ibanezmatt13: folk do
[09:40] <Brace> however you've got to make sure that it'll clear any nearby buildings in time
[09:40] <ibanezmatt13> Just seems like it would probably lower the chance of recovery
[09:40] <Brace> so if it's really windy and is rising slowly, it'll hit the building before it's high enough
[09:41] <costyn> ibanezmatt13: well it would because you can less accurately measure necklift during filling
[09:41] <costyn> ibanezmatt13: so you don't know if you've put in enough helium
[09:41] <ibanezmatt13> That's another thing, how is line of sight affected by buildings. If my balloon drifts quite far laterally, is there a high chance of me loosing line of sight?
[09:41] <costyn> ibanezmatt13: as for the path it will take, the predictor will take into account ground winds too
[09:42] <ibanezmatt13> In fact, with the height it's at that probably wont happen
[09:42] <ibanezmatt13> this predictor seems like a good tool
[09:43] <ibanezmatt13> I didn't realise how expensive the price of helium was these days.
[09:43] <gonzo_> if it's more than a breeze, I suspect you will have problems releasing without the payload being dragged along the ground.
[09:43] <costyn> gonzo_: that too yes
[09:43] marcosscriven (~marcosscr@cpc14-slam6-2-0-cust507.2-4.cable.virginmedia.com) left irc: Remote host closed the connection
[09:43] <costyn> gonzo_: had trouble with that myself on my first launch
[09:43] <ibanezmatt13> gonzo_: probably yes
[09:44] <gonzo_> there is some info on a 'two line launch' on the wiki. But I guess that would still be a problemn if the whole rig is blown horisonta!
[09:44] <costyn> several radials were bent which made the signal fluctuate
[09:45] <ibanezmatt13> how will I work out what balloon I need? I was looking at the Hwoyee 800g. It says it's rated up to 30,000m (nearly 100000ft)
[09:45] <costyn> ibanezmatt13: really depends on your payload weight
[09:45] <ibanezmatt13> say it was between 800-900g?
[09:45] <costyn> ibanezmatt13: once you have that (or an indication) you can decide which balloon
[09:45] <costyn> ibanezmatt13: play with the calculator http://habhub.org/calc/
[09:46] <costyn> with a payload mass of 900g, and a balloon of 800g and ascent rate 5m/s you'll get to about 28KM
[09:46] <costyn> with 3000L of Helium
[09:46] <ibanezmatt13> that's pretty good
[09:47] <ibanezmatt13> I'm aiming for 30,000m, it says with 2609L helium I can get there in 99mins
[09:48] <Brace> hadn't seen that calc, looks good
[09:49] <ibanezmatt13> why is it that less helium makes it go higher???
[09:49] <Randomskk> bursts later
[09:49] <costyn> Brace: the predictor and the calc are the 2 most important HAB tools
[09:49] <ibanezmatt13> that's interesting. So is it worth going for less helium
[09:50] <costyn> ibanezmatt13: well except that at a certain amount the balloon will float and you won't recover your payload
[09:50] <ibanezmatt13> in fact, i just realised that it makes the accent rate pretty slow
[09:51] <costyn> ibanezmatt13: it's really advisable to keep the ascent rate at around 5m/s
[09:51] <costyn> certainly not lower than 4
[09:51] <ibanezmatt13> if I aim for 5, that should be fine. How much will the helium cost?

[09:52] <Brace> ibanezmatt13: there's al ist on the wiki of costs
[09:52] <costyn> ibanezmatt13: balloon and helium will be your biggest costs

[09:57] <ibanezmatt13> Realistically, do you think It'll be possible to keep my payload weight down to 600/700g if I just have a Pi, GPS, Radio, and camera, in a very light weight payload box?
[09:57] <Brace> ibanezmatt13: http://ukhas.org.uk/guides:balloon_data
[09:58] <Brace> ibanezmatt13: that's exactly what I'm planning and it seems feasible
[09:58] <Brace> just start weighing stuff and then you'll know what you've got
[09:59] <Brace> eg an rpi is 45g
[09:59] <ibanezmatt13> It does seem feasible to keep weight down to 600/700h
[09:59] <Brace> less if you remove any ports you don't need (eg unsolder the ethernet and HDMI)
[10:00] <ibanezmatt13> If I just unsoldered it, would it not cause me any problems? I.e, short circuits or whatever
[10:00] <Randomskk> I'd probably not try unsoldering
[10:00] <Randomskk> it's light enough as it is
[10:00] <Brace> well daveake has done that on his
[10:00] <Brace> it's up to you really
[10:00] <ibanezmatt13> For power efficiency, is it hard to disable the video chip on the Pi. I believe it take quite a bit of powe, yet it is not at all needed
[10:01] <Brace> an AA battery is roughly 25gms
[10:01] <Brace> so on and so forth
[10:01] <Brace> currently I'm planning, arduino, gps, radio, rpi, rpi camera and batteries
[10:02] <Brace> should come in nicely under 800gms
[10:02] <ibanezmatt13> See, I am only using one Pi. And no arduino. So it should be less than that for me?
[10:02] <Brace> and aiming for 30k +
[10:02] <ibanezmatt13> should be fine then :)
[10:02] <costyn> Brace: why rpi with camera? are you doing ssdv?
[10:02] <Brace> costyn: it's what we've got in the parts bin

[10:03] <Brace> there was a time when sending photos back to earth was an option
[10:03] <ibanezmatt13> I think for my first flight I'll have a seperate HD video camera, not connected to Pi. Simplicity for me :)
[10:03] <Brace> but my mate doesn't think he's got the time at the moment
[10:03] <Brace> he's the one who bought the rpi and the rpi camera
[10:04] <ibanezmatt13> I'm gonna have to go now, end of free lesson. Have a good day :)
[10:04] <costyn> I'd always use a Canon stills camera with CHDK over a Pi
[10:04] <Brace> think he already had a couple of pis, so the camera is £17ish, so he just bought that as we currently don't have a suitable camera

[10:05] <costyn> for a A480 for example
[10:06] <Brace> that is pretty cheap
[10:06] <Brace> well, we'll see how building the payload goes
[10:07] <Brace> if he gets his bit done in time, then we'll try that
[10:07] <costyn> I would really advise against using an RPi if you're only going to be taking pictures with it

[10:58] <Greenwood> hello - to buy the actual balloon, is there any well regarded brand? As in, is Hwoyee better than Totex?
[10:59] <Randomskk> heh
[11:00] <Randomskk> if anything the other way around, but they are more "different" than "better" maybe
[11:00] <Randomskk> totex balloons are more reliable at bursting when you expect
[11:00] <Randomskk> but hwoyee balloons pretty much gave all the altitude records - sometimes they just keep on going up
[11:00] <costyn> usually they're fine
[11:00] <Randomskk> yea
[11:00] <Randomskk> only in specific fill conditions does it tend to be an issue
[11:01] <costyn> Greenwood: http://ukhas.org.uk/general:flight_data
[11:01] <costyn> Greenwood: most hwoyee's reach higher than calculated
[11:02] <Greenwood> costyn: that's why they're out of stock then... thank you

[11:50] <Babs> Morning all - Does the balloon predictor assume that the first x thousand of fall after burst comes in effectively like something falling in a vacuum, and only below a certain altitude does the descent rate kick in?
[11:51] <UpuWork> it knows if 5m/s is predicted
[11:51] <UpuWork> it will be 10m/s @ 10k etc
[11:51] Greenwood (c2502009@gateway/web/freenode/ip.194.80.32.9) left irc: Quit: Page closed
[11:54] <Babs> ahhh ok. Thanks UpuWork. I am obsessed with your hourly launch predictor btw. Interestingly, it predicts a landing within 100m of my mates garden in Wolverhampton if I launch at 4am on Tuesday.
[11:54] <UpuWork> lol
[11:54] <SpeedEvil> :-)
[11:54] <UpuWork> well I would run the normal predictor as well but the results *should* be the same
[11:54] <mattbrejza> remember the predictor assumes ground level as 0m
[11:54] <daveake> Not bad:-). I had a play with predictions and got within 800m, but not that close
[11:55] <daveake> (within 800m of the launch site)
[11:55] <UpuWork> really 24 hours before is about it for accuracy
[11:55] <daveake> yep
[11:55] <UpuWork> but also you can see how quickly its moving
[11:55] <Babs> Whats the nearest someone has got a launch to land?
[11:55] <UpuWork> like if an hour makes a difference between green fields and Gatwick I probably wouldn't be lauching
[11:55] <mattbrejza> also if its due to be going 100mph at 30km+ there may be somewhat more variation on the landing location
[11:56] <Babs> It would be awesome to launch, walk to the next field, get a deckchair and look up for 2 hours
[11:56] <UpuWork> Dave and I had one land 10 miles from launch ?
[11:56] <Babs> stoke up the bar b, that kind of thing
[11:56] <Babs> That's pretty close
[11:59] <Babs> At the moment my sat launch gets it landing on the spire on Bristol Cathedral
[11:59] <Babs> Which would be impressive but makes me lean towards Sunday instead ;-)

[15:18] <GW8RAK> You are unlikely to hear any datamodes on UHF. But on HF you should hear PSK31 around 14.070
[15:18] <eroomde> you'll here some droning on your 70cm repeater
[15:19] <eroomde> but it's not data
[15:19] <eroomde> hear*
[15:19] <ibanezmatt13> there is an operational 70cm repeater pretty close to me
[15:19] <GW8RAK> Tune in to that
[15:20] <ibanezmatt13> I guess I tune into the one that says repeater output, 434.85?
[15:20] <Geoff-G8DHE_> Should be able to decode the Morse Ident from the repeater every 15minutes using dl-fldigi
[15:21] <ibanezmatt13> there's a morse ident
[15:21] <ibanezmatt13> ?

[15:21] <Geoff-G8DHE_> License requirement for amateur radio operation to ident every 15 minutes minimum
[15:22] <ibanezmatt13> so how should I set up dl-fldigi in this instance?
[15:22] <Geoff-G8DHE_> repeaters generally use morse, some have a synth. voice but not many
[15:22] <Geoff-G8DHE_> Select Morse as opposed to RTTY
[15:22] <ibanezmatt13> Ok, and then do I just put in the frequency?

[15:23] <mfa298> the simplest test might just be to see if you see stuff on the waterfall in dl-fldigi, you should see the dots and dashes appear when the repeater idents.
[15:23] <Geoff-G8DHE_> actually its CW on the Tab,
[15:23] <ibanezmatt13> ah right
[15:24] <ibanezmatt13> is that all i have to do? Set mode Morse and change the CW?
[15:24] <Geoff-G8DHE_> you dont have to put the freq in to fldigi that nfo is only for the log book, the freq. is actually set by the Rx
[15:24] <Geoff-G8DHE_> You might want to change bandwidth etc. but the defaults should be fine
[15:24] <ibanezmatt13> oh right. So it's just a case of setting the mode and listening
[15:25] <mfa298> the simplest test might just be to see if you see stuff on the waterfall in dl-fldigi, you should see the dots and dashes appear when the repeater idents - although until you know what things sound like it can be a challenge knowing what to set in fldigi. - There are a couple of flights over the weekend you can try listening for as well.
[15:26] <mfa298> hmmm, that's not what i typed. I must have hit the history.
[15:26] <ibanezmatt13> I'll make sure I'm set up for the weekend
[15:27] <mfa298> if you want to try finding some rtty (or other digial modes) you could try HF (14.0 -> 14.1 is often good) but you'll probably want a longer bit of wire as an antenna.
[15:27] <chrisstubbs> :D Yay PCB's http://farm8.staticflickr.com/7324/8786862814_69065cf438_c.jpg
[15:27] <mfa298> and until you know what things sound like it could be a lot of trial an error to set the right mode on fldigi
[15:27] <ibanezmatt13> I'll experiment. Thanks again, off for my tea now. Speak soon :)

[15:35] <chrisstubbs> thats not scaled very well
[15:36] <chrisstubbs> the new one is a bit smaller. not much thought becuase i wanted to add the sdcard

[15:38] <Randomskk> yes, all that analysis that everyone does :P
[15:38] <HixWork> I like the idea of SD
[15:38] <eroomde> well they don;t because the have none datas

[16:28] <mfa298> I thought I'd give it a go again as people always say its good. But when I get kernel panics and issues with IPv6 it just never seems worth it.
[16:30] <craag> Haven't tried much ipv6 with it I must admit.
[16:31] <mfa298> I think the IPv6 issue this time is because I've got dhcpv6 setup rather than just SLAAC
[16:32] <mfa298> although i think ipv6 has always caused some sort of problem for ubuntu.
[16:33] <craag> Yeah I repeatedly kernel-paniced ubuntu about a year ago trying to use ipv6 on eduroam. That particular issue was fixed in 2.6.39 though.
[16:34] <mfa298> these kernel panics were due to bluetooth. Which is a pain having just got a new wifi/bluetooth card as the old one the bluetooth didnt work

[18:20] <ibanezmatt13> Good Evening :) I have my radio reciever set up. It's on my window ledge and is plugged into the mic socket on my PC
[18:20] <ibanezmatt13> I'm gonna try to get the morse from a local repeater near me but I'm not sure if my area is covered
[18:21] <arko> whats your output power?
[18:21] <ibanezmatt13> I've no idea
[18:22] <ibanezmatt13> Is it likely to be LSB or USB?
[18:22] <arko> are you doing RTTY?
[18:22] <arko> if so USB
[18:22] <ibanezmatt13> no, morse, just to test
[18:22] <arko> oh
[18:23] <ibanezmatt13> I'm not sure exactly what I need to do though.
[18:23] <LazyLeopard> What part of the world are you in?
[18:23] <ibanezmatt13> http://www.ukrepeater.net/70cm.htm I am looking at the one near Liverpool.
[18:23] <ibanezmatt13> LazyLeopard: I'm in NW England
[18:24] <arko> im going to guess usb
[18:24] <arko> above 10Mhz it's USB right?
[18:25] <mfa298> ibanezmatt13: for a local repeater it will be FM or NFM
[18:25] <mfa298> shoudl work with either (if you've got a choice)
[18:25] <ibanezmatt13> Well, the repeater has an input and an output frequency. I guess I want the output? I'll try fm
[18:25] <LazyLeopard> OK. That'll be an FM repeater.
[18:25] <arko> wait, morse over FM?
[18:25] <ibanezmatt13> This all looks a little confusing. I'm in dl-fldigi now
[18:26] <ibanezmatt13> it says 70cm band
[18:26] <mfa298> arko: they're voice repeters for amateur radio and as part of the regs have to ident every 15 minutes
[18:26] GW8RAK (~chatzilla@host-2-99-27-212.as13285.net) joined #highaltitude.
[18:26] <arko> oh
[18:26] <mfa298> which is usually done as morse over FM (some now have a voice ident instead)
[18:26] <LazyLeopard> You'll not see anything particularly useful in fldigi from that.
[18:26] <arko> so you generate the tones?
[18:27] <ibanezmatt13> Do I tune the output or input frequency into my reciever (probably a stupid question). I'm trying to see the morse code every 15 mins
[18:27] <arko> i always thought morse is an upper side band thing
[18:27] <LazyLeopard> ...but you'll hear voices if you tune to the output and someone's using the repeater.
[18:27] <arko> on off
[18:28] <GW8RAK> A repeater ident is just audio tones on the FM carrier
[18:28] <ibanezmatt13> input: 433.2500 output:434.8500 Any idea which one?
[18:28] <GW8RAK> Tune to the output
[18:28] <ibanezmatt13> thought so
[18:28] <ibanezmatt13> And is it definitely fm?
[18:28] <GW8RAK> Yes
[18:28] <LazyLeopard> Yes
[18:29] <mfa298> arko: normally morse is just a turning on and off the carrier frequency (so you can reciever it using usb in the same way we do rtty)

[18:30] <GW8RAK> Change the mode to FM

[18:30] <arko> mfa298: ah i thought so, was wondering

[18:32] <ibanezmatt13> I'm having trouble setting the modes in dl-fldigi though. I need morse mode, and somehow i need to enter the frequency
[18:32] <GW8RAK> Then start listening. If you don't hear anything there, which is likely as 70cm is often dead, try a local 2m/145MHz repeater
[18:33] <ibanezmatt13> How do i start listening. You mean in the program right?
[18:34] <GW8RAK> Turn on radio, set squelch, engage ears and wait for something to happen.
[18:34] <ibanezmatt13> i see :)

[18:35] <ibanezmatt13> I think I'll try something a little more promising. I'll try a different repeater
[18:35] <ibanezmatt13> Ooh, I'm getting something!
[18:35] <GW8RAK> Patience Grasshopper
[18:36] <ibanezmatt13> I'm just getting the odd burst of nouse
[18:36] <ibanezmatt13> noise
[18:37] <mfa298> for repeters they'll mostly be quiet unless they're being used
[18:37] <ibanezmatt13> I guess my chances of even picking one up is slim. There not that near
[18:37] <nigelvh_> If you get a little bit of occasional noise, your squelch is set too low.
[18:38] <Tommo> or your not married
[18:38] <ibanezmatt13> I'm sure I just heard morse???
[18:38] <ibanezmatt13> It was noise, but it was like dots and dashes
[18:38] <mfa298> you should be able to hear a repeater thats 10-30 miles without too much issue
[18:39] <nigelvh_> Perhaps you have a weak signal, but morse should be pretty clear beeps.
[18:39] <ibanezmatt13> no it's not beeps
[18:39] <ibanezmatt13> I've tried two repeaters
[18:40] <Tommo> 144.800mhz??
[18:40] <mfa298> you might need to stay listening to one for >15 mintues to hear anything if they're not activly being used
[18:40] <ibanezmatt13> Am i likely to pick that up?
[18:40] <ibanezmatt13> good point
[18:41] <ibanezmatt13> So if I get the odd burst of noise, does that mean the repeaters definitely online?
[18:41] <mfa298> if it's jsut a short burst of white noise that probably just means you're squwelch is a bit low
[18:42] <mfa298> the squelch just acts to make the radio silent if the signal is under a certain level.
[18:43] <ibanezmatt13> I've set the squelch a little higher, do you think the repeater is definitely online. It says on the website that it isn't but I keep hearing things
[18:44] <ibanezmatt13> is NFM correct?
[18:44] <mfa298> you'de need to ask a local ham if it's online or not
[18:44] <mfa298> NFM should be the right setting.
[18:45] <mfa298> even if the repeater is FM rather than NFM you'll hear something (and I think all repeaters should be NFM now)
[18:45] <GW8RAK> Where are you ibanezmatt13?
[18:45] <ibanezmatt13> Guys, I'm not getting beeps, but if I turn the squelch down, I definitely get morse
[18:45] <ibanezmatt13> I'm in NW England, Wigan
[18:46] <Tommo> I was thinking 144.800 as theres always someone on packet... its comforting to chear the odd squeel of packet
[18:46] <Tommo> hear
[18:46] <ibanezmatt13> I'll give it a go
[18:47] <ibanezmatt13> 144.8 is working in the same way.
[18:47] <Tommo> if you here anything it will be just a squeel of packet data
[18:48] <ibanezmatt13> It's just random bursts of noise like before. Like dots and dashes actually...
[18:48] <mfa298> if you're hearing the same on 144.8 as you did for the repeater then your not hearing actual signals
[18:48] <Geoff-G8DHE> fldigi won't decode packet radio so you will only hear it
[18:48] <ibanezmatt13> that's what I thought
[18:48] <ibanezmatt13> The reciever works fine though, I tested it on something else before
[18:50] <Geoff-G8DHE> You need to be a bit patient with the repeaters, unless someone has activated it then after a few seconds the repeater shuts down and there is nothing to hear.however it will pop up every 15 minutes and send the callsign
[18:50] <GW8RAK> If you know the receiver is working okay, then you'll have to accept that UHF is not the busiest band. I would suggest just leaving it monitoring the UHF repeater in the hope someone uses it.

[18:50] <Geoff-G8DHE> If it is activated then you will hear people talking thru it, with beeps to indicate the end of transmissions and the like
[18:51] <ibanezmatt13> That's not happening :(
[18:51] <ibanezmatt13> I assume it's all set up right. I'm on NFM
[18:51] <mfa298> its not a great recording but this is what you should hear on 144.80 https://www.youtube.com/watch?v=iMnEsJRY138
[18:51] <Tommo> I think its just a case of being patient
[18:52] <ibanezmatt13> Yeah I agree, which one should I tune in to?
[18:52] <Geoff-G8DHE> tune to 434.85 NBFM and leave the squelch open and turn the volume down so that its not to loud and then do something else for a while! You will hear it if it coms up

[18:52] <ibanezmatt13> ok, I'll do that

[18:53] <ibanezmatt13> Before I mixed up the input and output, I think 434.85 was the input
[18:53] <mfa298> repeaters tend to be busiest during rush hour (if they ever get busy) as they're designed for mobile stations.
[18:54] <ibanezmatt13> i see
[18:54] <ibanezmatt13> shall i leave the squelch on 1
[18:54] <Geoff-G8DHE> Yes you did its output is on 433.250 so tune to that
[18:55] <ibanezmatt13> I'm on that now, squelch is open and I'm just getting noise
[18:55] <mfa298> that's all you'll get most of the time
[18:56] <Geoff-G8DHE> Up to you but if you don't know how sensitive the squelch is you might possibly be setting it to high and you won't hear it, not sure what the signal path is like between you and it so ...

[18:56] <mfa298> at some point in the next 15 minutes it will become active for a few seconds to identify itself
[18:57] <ibanezmatt13> will i hear it above the constant noise?
[18:57] <Geoff-G8DHE> Yes if the squelch is off and your in range
[18:57] <mfa298> if there's any local(ish) repeater that's still active locally Imight try to record what it does (most of the local repeaters are currenly off)
[18:57] <ibanezmatt13> is this one definitely on? If I hear noise does that mean it's on?
[18:58] <mfa298> ibanezmatt13: the noise you're hearing is similar to what you get if you don't tune into a station on an FM radio it's effectivly indicating there is currently no signal (which is what you'll get from a repeater most of the time)
[18:58] <Geoff-G8DHE> Yes, you will hear the noise go down as the carrier switches on, then the morse tones will appear and then it will switch back off again and the noise level will increase.
[18:58] <ibanezmatt13> Ok, .
[18:59] <ibanezmatt13> And this should happen in less than 15 minutes?
[18:59] <Geoff-G8DHE> Yes
[18:59] <ibanezmatt13> ok
[18:59] <GW8RAK> Which repeater are you tuned to ibanezmatt13
[19:00] <Geoff-G8DHE> GB3LI
[19:00] <ibanezmatt13> the one near Liverpool. G3WIC
[19:00] <GW8RAK> Listen now and I'll open it for you and you'll hear the morse ident as I go off
[19:01] <ibanezmatt13> which one?

[19:02] <ibanezmatt13> Am I tuned into the right one?
[19:02] <Geoff-G8DHE> 433.250 is GB3LI
[19:02] <ibanezmatt13> yeah that's the one
[19:03] <Upu> we recruiting Radio Amateurs :)
[19:03] <ibanezmatt13> indeed
[19:03] <Upu> evening
[19:03] <GW8RAK> Listen and you should hear the morse ident if it is within your range
[19:03] <ibanezmatt13> im listening
[19:03] <GW8RAK> Did you hear anything?
[19:03] <Geoff-G8DHE> Most of the letters tend to have a link with the local area - GB3BR is in BRighton on 70cms GB3SR is Southern Repeater also in Brighton (same location) but on 2m
[19:04] <GW8RAK> Cos it's a strong signal over hear
[19:04] <ibanezmatt13> it went off and on rapidly just like morse, but it was just the gaps in the noise, no beeps
[19:04] <GW8RAK> Did it sound like white noise or an audio tone?
[19:04] <ibanezmatt13> noise
[19:04] <Tommo> --. -... ...-- .-.. ..
[19:04] <Geoff-G8DHE> Is the mode switch set to NBFM not USB or LSB or AM
[19:05] <ibanezmatt13> It's on NFM

[19:06] <GW8RAK> 1
[19:07] <ibanezmatt13> ok, my Dad thinks he heard something, but he wasn't sure
[19:08] <GW8RAK> Can you more into the garden or an upstairs room with a better "view" of the repeater?
[19:08] <Geoff-G8DHE> The other option might be a Manchester repeater much the same distance
[19:08] <mfa298> GW8RAK: is it worth doing a "checking access" bit of speach as well (assuming you didn't do that) might give something a bit longer to listen for
[19:08] <GW8RAK> I think I can open taht one as well
[19:08] <ibanezmatt13> are there any functioning manchester ones? And I am upstairs hanging out of my window :)
[19:08] <Tommo> i see a balloon on test today on spacenear.us callsign mondo very close to me
[19:09] <ibanezmatt13> shall i stay on the same frequency?
[19:09] <Upu> try GB3YW ibanezmatt13
[19:09] <ibanezmatt13> what's the frequency?
[19:09] <Upu> 145.7875Mhz
[19:09] <Upu> tell me when you're tuned in I'll key it up
[19:09] <ibanezmatt13> NFM?
[19:10] <Upu> yes
[19:10] <Upu> not speaking or someone may try to talk to me
[19:10] <ibanezmatt13> is it east or west of me, man or liverpool?
[19:10] <Upu> its out towards Halifax
[19:10] <Upu> back in a sec
[19:10] <ibanezmatt13> Ok, I'm ready
[19:10] <mfa298> they're obviously more friendly oop norf. Most of the times I've put a call out on a repeater no ones ever come back to me
[19:10] <Geoff-G8DHE> Its in Flockton no idea where that is myself
[19:11] <ibanezmatt13> what shall i set the squelch to?
[19:12] <Geoff-G8DHE> Leave the squelch OPEN at all times until you get a signal to pla with
[19:12] <Geoff-G8DHE> *play
[19:12] <Upu> ok
[19:12] <Upu> there will be some silence then there should be some morse
[19:12] <ibanezmatt13> ok, squelch 0, ready?
[19:12] <Upu> get that ?

[19:15] <Upu> what are you trying to do listen in?
[19:15] <Geoff-G8DHE> One second looking
[19:15] <ibanezmatt13> yep
[19:15] <Upu> what radio do you have ?
[19:15] <GW8RAK> ON 70cm, GB3LI is your best bet and I can open it from here
[19:15] <ibanezmatt13> an Alinco DJX-10
[19:15] <chrisstubbs> nigelvh, ooo self etched?
[19:16] <Tommo> what antenna are you using
[19:16] <Upu> what frequency GW8RAK ?
[19:16] <Geoff-G8DHE> GB3MI is on 145.7125 and operational
[19:16] <Upu> and where is it ? I'll spin the antenna round
[19:16] <ibanezmatt13> Just the normal built in one
[19:16] <GW8RAK> 433.250
[19:16] <Upu> give me a few mins
[19:16] <Geoff-G8DHE> Its North of the City centre and closer to Wigna than the Yorkshire one but not sure if UPU can access it ?
[19:17] <Upu> probably not but let me spin the antenna round
[19:17] <GW8RAK> ibanezmatt13, can you see the Welsh hills from your garden or a clear view across to the west?
[19:17] <Upu> bootle
[19:18] <ibanezmatt13> we cant see from here, but theres a point 5 mins away from here where you can see manchester city centre and liverpool and the welsh mountains (billinge hill)

[19:18] <ibanezmatt13> well, 2 mins away really
[19:19] <Upu> nope I can't open that from here sadly
[19:19] <GW8RAK> Tune to 434.650 and I'll put out a 50W carrier on FM. It WILL get to Wigan as I can see it from the aerial location. No audio, just a carrier, so the white noise should drop away
[19:20] <ibanezmatt13> Still NFM?
[19:20] <ibanezmatt13> which side are you on?
[19:21] <Geoff-G8DHE> There isn't any side to Frequency Modulation different mode from Sideband Upper/lower
[19:21] <GW8RAK> I'm on top of the Welsh mountains you can see from your area
[19:21] <GW8RAK> Tuned in?
[19:21] <ibanezmatt13> Yes
[19:21] <GW8RAK> tx ing now
[19:21] <Upu> negative from here
[19:22] <ibanezmatt13> neg from here too
[19:22] <ibanezmatt13> we got two beeps
[19:23] <GW8RAK> any more beeps?
[19:23] <ibanezmatt13> squelch is open, lots of white noise, but we heard something, I think. No more beeps
[19:23] <Tommo> Roadrunner??
[19:23] <GW8RAK> No idea. I know I can reach Wigan from here, so it's down to your location
[19:24] <Tommo> Antenna??
[19:24] <ibanezmatt13> Shall we have a quick trip up to Billinge hill? The antenna is standard
[19:25] <Geoff-G8DHE> It will be a small helical on the handheld, should be adequate

[19:26] <mfa298> location can make a big difference.
[19:26] <GW8RAK> Unfortunately I'm off to the radio club in a moment. If you want to try tomorrow or over the weekend, I can help then
[19:26] <Geoff-G8DHE> Only other method would be to set it scanning all the repeater output channels and then sit back for a while to see what appears
[19:26] <ibanezmatt13> we are surrounded by houses in a bit of a dip
[19:26] <Tommo> I cant receive anything but locals on my handheld.. but the colinear in the loft works wonders
[19:27] <ibanezmatt13> do any of them beep all the time?
[19:28] <Geoff-G8DHE> Not as such they tnd towards being off until activated by an incoming signal
[19:28] <Geoff-G8DHE> *tend
[19:28] <ibanezmatt13> we could try a range of local repeaters and scan.
[19:29] <ibanezmatt13> And it's definitely NFM?
[19:29] <Geoff-G8DHE> in that case scan between 433.000 and 433.375 thats the majority of outputs
[19:29] <mfa298> almost all amateur radio traffic is NFM
[19:29] <ibanezmatt13> ok
[19:29] <Geoff-G8DHE> on UHF
[19:29] <ibanezmatt13> we're ready to try something, any ideas?
[19:30] <mfa298> on UHF and VHF (Should have added that above)
[19:30] <GW8RAK> Try 433.975. Echolink repeater
[19:31] <Geoff-G8DHE> Set it into scan mode between those two freqencies and then sit back, you may have to set the squelch to the lowest level for it to scan however
[19:31] <ibanezmatt13> east or west?
[19:31] <GW8RAK> Gone quiet now
[19:32] <ibanezmatt13> I'm just getting noise
[19:32] <mfa298> If you want to listen for repeaters you might do better listening for 2m repeaters as they should have a slightly larger range and tend to be more active.

[19:43] <ibanezmatt13> if I'm constantly getting noise and the repeater sends out an ident, will i be able to hear the beeps on top of the noise?
[19:44] <GW8RAK> ibanezmatt13 - if you can get to billing hill over the weekend, I can put out a signal that you can tune to. Probably even a balloon tracker as well
[19:44] <GW8RAK> Checked the path prediction and it'll be a big signal with you
[19:44] <ibanezmatt13> that would be excellent
[19:44] <Geoff-G8DHE> Southport was being moved in late Feb so it ought to be back up, but nothing on the keepers web site http://g4eid.wordpress.com/category/amateur-radio/gb3oa/
[19:44] <mfa298> ibanezmatt13: the white noise is just what you hear when there's a lack of signal
[19:45] <mfa298> it should go quiet if there's a signal you can recieve
[19:45] <ibanezmatt13> Ah right
[19:45] <ibanezmatt13> Only problem with Billinge Hill is the lack of interent

[19:45] <GW8RAK> ibanezmatt13, I've got to go, but give me a shout on Friday if you want to try.
[19:45] <ibanezmatt13> will do, good night :_)
[19:45] <Geoff-G8DHE> Thta's how the squelch works, it listens for noise and turns the Audio off if there is noise, opens the audio up once the noise fades
[19:45] <ibanezmatt13> :)
[19:46] <ibanezmatt13> so for listening for things like this I should have 0 squelch yes?
[19:47] <Geoff-G8DHE> Yes to start with, once you know the rig, you will understand where to set the squelch, but when you first try to find a weak signal best to leave the squech out of the equation!
[19:47] <Babs> ping Upu
[19:47] <mfa298> for FM/NFM you should be able to set the squelch higher but for testing it's better to leave it open (on 0)

[19:48] <Babs> Hey Anthony - live predictor - can anyone set it up ahead of time for me/what do i need to supply to whom?
[19:48] <mfa298> The squelch control is a filter that stops you hearing anything if the signal is lower than where it's set. If it's open you'll hear anything you can pick up.
[19:48] <Geoff-G8DHE> Good luck for tomorrow then!

[20:14] <nigelvh_> Upu, have you tested NOT using flight mode with the uBlox's, do they just not report higher altitudes or do they start doing weird stuff?
[20:15] <nigelvh_> My tracker won't be an issue to set flight mode, but I'm going to fly some cheap commercial APRS transmitters that I'm not sure I can program to send the command.
[20:16] <fsphil> Babs: yea I can do that if I'm about, when you launching?
[20:16] <nigelvh_> I may power the GPS, send the command, and then connect it to the commercial tracker without un-powering it.
[20:16] <chrisstubbs> nigelvh, cool :)
[20:17] <chrisstubbs> odd, can someone do me a favour and send "chrisstubbs hello" and chrisstubbs, hello"
[20:18] <Upu> nigelvh I think they just stop reporting location information until they get below the altitude
[20:18] <Upu> stick an EEPROM On it nigelvh
[20:18] <daveake> IIRC this happened on a flight
[20:19] <Upu> you can program it save it then it will keep that setting on power up
[20:20] <nigelvh_> Yeah, but adding an eeprom is a pain. And I've only got about a week and a half, so not a ton of time.

[21:15] <mfa298> a 50R resistor will give you a 1:1 SWR but it's not a good antenna.

[21:33] <Upu> only a quick run round the block at this time of night
[21:34] <Upu> maybe they just need to teach you about contraception rather than villifying it
