[00:05] <F6AGV> I was in visit to the last UKHAS conference in Greenwich !
[00:05] <G8APZ> France is bigger.. but not so many enthusiasts
[00:06] <F6AGV> Yes is true
[00:06] <DL7AD> heee......

[00:07] <G8APZ> we are a strange nation!
[00:07] <F6AGV> B-17 is up again !
[00:07] <DL7AD> :D rofl
[00:07] <DL7AD> detached from the trees
[00:07] <F6AGV> ice on enveloppe perhaps ?
[00:08] <DL7AD> yes definetly
[00:08] <G8APZ> B-17 rested and took off into the sky
[00:08] <F6AGV> very incredible flight indeed !
[00:09] <KT5TK> B-17 is seriously going up to float altitudes...
[00:09] <F6AGV> if you want to mail me: f6agv on free.fr
[00:09] <arko> i cant hear it :(

[00:11] <arko> oh oops
[00:11] <arko> im looking for B-17
[00:11] <enkidu> DL7AD: you scared it

[00:12] <F6AGV> B-17 is 434.500
[00:12] <G8APZ> 10mW on HF... you need a very quiet QTH
[00:12] <arko> right
[00:12] <arko> i doubt i'll hear it on this global tuner
[00:12] <KT5TK> http://websdr.oh2lak.net:8901/

[00:18] <arko> ok
[00:18] <arko> got my setup working at my lecture hall
[00:18] <arko> this lecture is boring anyway
[00:19] <arko> rather try tuning to habs in other countries
[00:20] <DL7AD> already warned some hams in finland.
[00:20] <arko> how wide is the signal?
[00:21] <DL7AD> around 200...300hz
[00:21] <arko> hmm
[00:22] <KT5TK> well, the beeps are just cw
[00:22] <arko> damn it
[00:22] <KT5TK> maybe 20 Hz
[00:22] <arko> KT5TK: how are we both tuning it?
[00:23] <KT5TK> No need to tune.
[00:23] <KT5TK> But you can simply click with your mouse on the waterfall
[00:23] <arko> hmmm
[00:23] <arko> ok
[00:23] <KT5TK> actually below the waterfall
[00:24] <arko> right but no one has changed it
[00:24] <arko> its on b-17 balloon
[00:24] <KT5TK> yes, because all users are listening for B-17

[00:31] <DL7AD> u.o its descending again....
[00:31] <arko> ah bugger
[00:31] <arko> i cant seem to decode it/ hear it
[00:31] <SpeedEvil> np: Here comes the rain again.
[00:32] <arko> DL7AD: where do i put the two red lines?
[00:32] <enkidu> DL7AD: rainfall I believe
[00:32] <enkidu> got it on radar
[00:32] <DL7AD> rain is the problem. before we knew the exact landing spot. if it will land now, nobody will know exatcly
[00:33] <DL7AD> arko: 2 red lines? this is dominoEX16 not RTTY
[00:33] <DL7AD> arko: check your mode settings
[00:33] <arko> sorry im not too familiar with dominoEX16
[00:33] <arko> i hit auto config
[00:33] <DL7AD> yes
[00:33] <arko> so these two red lines dont matter?
[00:33] <DL7AD> with b-17 in the dropbx?
[00:34] <arko> yes
[00:34] <DL7AD> okay. you will get 2 yellow lines and.... second
[00:34] <DL7AD> no
[00:34] <DL7AD> you are right
[00:35] <DL7AD> do your hear the beep?
[00:35] <arko> nope
[00:35] <DL7AD> you have to click on the beep that both red lines have the same distance to the center of the signal
[00:36] <DL7AD> the red lines represent the edge of the signal
[00:36] <arko> i dont really have a signal
[00:36] <DL7AD> thats the same problem to me here :P
[00:37] <DL7AD> rofl i was kidding
[00:37] <enkidu> If only I had my antenna on roof already...
[00:37] <DL7AD> arko? where are you located?
[00:37] <enkidu> over sea refraction is so useful
[00:37] <arko> los angeles
[00:37] <arko> but im on a global tuner
[00:38] <DL7AD> arko: eh okay. that one from helsinki?
[00:38] <arko> http://websdr.oh2lak.net:8901/
[00:38] <arko> er i mean that

[10:00] <LeoBodnar> no problem oh1jcs you have helped a lot already!
[10:02] <oh1jcs> lol.. it woke me up with an 59+20 signal when it jumped back into the air. Had volume turned down but was enough to wake me. :)
[10:02] <OH1MN> If it picks up again, then me and OH2BUF, OH2LKV will hopefully catch it.

[10:12] <Rebounder-SM3ULC> ",%s" ?
[10:12] <ibanezmatt13> right, I'll try it
[10:12] <ibanezmatt13> nope
[10:12] <mfa298_> or %s, for the $GPGGA part
[10:13] <ibanezmatt13> just tried that, same output
[10:13] <mfa298_> as a silly question you did recompile inbetween ?
[10:13] <ibanezmatt13> I think so yeah
[10:14] <ibanezmatt13> yep I did
[10:14] <Geoff-G8DHE> Is there not an explode function in C ?
[10:14] <ibanezmatt13> don't know. I thought of splitting it by comma but then I realised my brain is coded in Python
[10:15] <mfa298_> in my code I'm looping through the string seperating at commas and using a state machine to do the right thing with the data,
[10:15] <Geoff-G8DHE> I think I meant that as more of a hint the a question ;-)
[10:15] <mfa298_> if you went that route you might find strtok looks like the right function but it isnt
[10:15] <oh1jcs> Someone mentioned something about the freq. of B-17. I had cursor frecuency on 1444 tonight when it relaunched. fyi.
[10:16] <jonsowman> don't use strtok
[10:16] <mfa298_> but there is a function that does work for that.
[10:16] <jonsowman> you'll regret it

[10:25] <ibanezmatt13> it's a good page mfa298_, I'll read it
[10:25] <mfa298_> I dont think you need the single quotes in there.
[10:26] <mfa298_> if you don't understand what the [^,] is doing read up on regular expressions - They can be really powerful - and you'll want to know more about them to match the rest of the string
[10:27] <mfa298_> stackoverflow can be a great source of answers if you can find someone asking the same question.

[10:31] <Vostok> might have landed
[10:31] <DL1SGP> we assume it initial re-lift-off was helped by sneaky ninja squirrels yo5pjb
[10:31] <mfa298_> the comment on the stack overflow page about specifying width is good as well as it means you won't get a buffer overflow if you get bad data
[10:32] <Vostok> we also assume the squirrels fixed the whole produced by OH7FXK who shot down the balloon in the first place
[10:32] <Vostok> *hole :)
[10:32] <mfa298_> think about what would happen if the time from gps was corrupt and had something that wasn't a . in it.

[10:38] <DL1SGP> there was a red cross group starting a balloon last year in Germany... their payload was not attached properly so in effect... the balloon flew without it...
[10:38] <ibanezmatt13> yeah, I'll experiment
[10:39] <mattbrejza> c doesnt even really have strings G8APZ , it just has a fixed array in memory which you can use to store a string

[10:39] <mfa298> G8APZ: there are various string functions in C but the concept of strings in C is a bit more interesting, they're more an array of characters with the last character being a NULL
[10:40] <G8APZ> OK ... I'll have to keep away from C I think!!
[10:40] <mfa298> G8APZ: that probably wouldn't help in this case as the aim is to build up the sscanf command to pull out the useful data from the string

[10:47] <OH7HJ> Not a trace of it on the spot of last fix. Looking at the B-17 altitude curve, I wonder if it could have made a similar hop in the morning before we arrived at the spot to search it.

[11:29] <gonzo_> aprs from habs couldb eb an issue, as you would prob not wnat to fly a tranceiver, just a low power TX only. So it would be broadcasting over a very wide area, without checking the chan is clear
[11:29] <gonzo_> I know that is done from ground based beacons too, but they are restricted footprint
[11:30] <OH7HJ> Sure, 70 cm is just fine as long as the balloon keeps high. The problems come with the descend. During the last few hundreds meters of altitude, UHF signal is absorbed by forest.

[11:31] <gonzo_> there may be some effects, but it really is just the last few metres

[11:32] <OH7HJ> On plains and on water 70 cm range is good, but on ground with vegetation it vanishes sometimes even before the balloon is below theoretical radio horizon.
[11:32] <fsphil> 70cm antennas are also very hab friendly
[11:32] <fsphil> in terms of size
[11:34] <gonzo_> higher freqs, you get more directionality for the size. But for capture area (ie the amount of signal indiced in the antenna) it's about comparable. So to get the same signal, you need about the same amoung of metal
[11:34] <gonzo_> but for close in DFing, then 70cm ants are certainly more convenient
[11:34] <OH7HJ> With a 2 m yagi of the same size, one gets a range boost by about 50 % over 70 cm on mixed forest terrain, and with similar size 6 m yagi the range extension is doubled.

[11:35] <gonzo_> OH7HJ, is that purely from absorbtion?
[11:36] <OH7HJ> Correct, forest absorbs UHF signal, and still more SHF of course. Over water UHF and SHF travesl OK, but over vegetation they are almost useless for long distances.
[11:37] <M6GTG_Andrew> my 2m yagi makes my arms ache ;-) http://img.photobucket.com/albums/v323/Nerdsville/CIMG8262_zpsfaaa95cf.jpg
[11:37] <gonzo_> fair enough.
[11:38] <OH7HJ> We have made practical experiments with 'long' distance WLAN. Got easily 6 km over a lake, while over woods to get equal signal the distance decreases to 1 km or even less.
[11:40] Geoff-G8DHE-M (~Geoff-G8D@geoffg8dhe.plus.com) joined #highaltitude.
[11:40] <gonzo_> I still think that for HABs, the main limitaition is the line of sight. The absorbtion will only be significanty in the last few metres. When it has prbably dropped out of sight of all stations anyway. Though it will still be a factor when trying to recover it
[11:40] <OH7HJ> Also I am listening to 1.09 GHz mode-S aircraft transponder fixes. Have to get reception aerial over treetops to get acceptable range. Even then, the range is cut by 30 % on wet weather. Wet trees absorb UHF still easier.
[11:41] <gonzo_> similar effect we have with a 5GHz link. Over a 30km path, we are skimming the trees. If the ant on oine end is lowered by 20ft, we get 20+dB less signal

[11:53] <ibanezmatt13> So I needed all the fields up to satellites, but now there's some data I'm not interested in which I want to avoid before getting to altitude a little further ahead

[11:59] <ibanezmatt13> ok, I get it
[11:59] <mfa298> sscanf is the same as scanf expcept scanf gets data from standard in (usually the keyboard) sscanf uses a stream (string , file etc)

[12:04] <DL1SGP> yeah neighbors can be a showstopper :(
[12:05] <ibanezmatt13> fsphil, I'm not sure where the * comes into it
[12:05] <ibanezmatt13> oh wait
[12:05] <ibanezmatt13> nevermind
[12:05] <ibanezmatt13> %2[^,] would become %*2[^,] ? fsphil
[12:05] <OH1MN_> well this one like the hobby...luckily not that much he would like to be a ham, but often asking about new stuff, dx, radios etc...
[12:06] <fsphil> ibanezmatt13: yea, though I doubt I'd bother putting in the number
[12:06] <fsphil> unless you can guarantee that field will have 2 characters
[12:07] <ibanezmatt13> what if the input string is corrupted?
[12:07] <M6GTG_Andrew> DL1SGP: I think I might find that out, newly licensed and looking at putting up some antennae, no idea what the neighbours and/or planning authority will say
[12:07] <fsphil> ibanezmatt13: not much you can do about that beyond making sure the checksum is fine
[12:07] <fsphil> (I assume you're processing gpgga strings?)
[12:08] <fsphil> and making sure it's null terminated
[12:08] <DL1SGP> M6GTG_Andrew: you will find out, if you got a good standing relation with your neighbours then seek the dialog and explain what you are up to
[12:08] <ibanezmatt13> yeah
[12:08] <ibanezmatt13> do I check the null at the end using the same function sscanf fsphil?
[12:09] <fsphil> what function are you using to read the line ibanezmatt13?
[12:09] <ibanezmatt13> sscanf
[12:09] <fsphil> before that I mean
[12:09] <fsphil> where is the string coming from?
[12:09] <ibanezmatt13> oh, well it will be the serial port eventually
[12:10] <ibanezmatt13> at the minute I've just set a string up as an example in the program
[12:10] <fsphil> ah
[12:10] <ibanezmatt13> https://gist.github.com/ibanezmatt13/6888125
[12:10] <fsphil> then it'll always be null terminated
[12:10] <ibanezmatt13> not quite sure what you mean
[12:11] <fsphil> C will put a 0x00 at the end of any literal string
[12:11] <ibanezmatt13> ok
[12:11] <fsphil> later on when you're reading it for real, just check whatever function reads the string puts the 0x00 at the end
[12:11] <fsphil> it probably will, unless you're reading it byte at a time
[12:12] <ibanezmatt13> So if I'm using sscanf in the same way as I am currently
[12:12] <fsphil> sscanf won't go past the 0x00
[12:13] <LeoBodnar> Laurenceb: so butane...
[12:13] <Laurenceb> heh
[12:13] <ibanezmatt13> see, the thing I'm thinking of, what if a comma is missed when it comes in, I'll end up overfilling the buffer won't I?
[12:13] <Laurenceb> LeoBodnar: or just launch when the weather is better
[12:13] <LeoBodnar> Why do you think sticking it in the main envelope is not going to work?
[12:13] <LeoBodnar> I am just curious
[12:13] <Laurenceb> i think B11 and 12 went well as they tracked a good area of air
[12:14] <LeoBodnar> Want to get through freezing clouds
[12:14] <Laurenceb> so no condensation
[12:14] <fsphil> ibanezmatt13: then specify the max size of whatever string you're writing the value into. that's sensible. but you can leave the value out if you're using * to skip it
[12:14] <LeoBodnar> yeah, it's too easy to fly in good weather
[12:14] <Laurenceb> butane in the envelope is diluted by the He
[12:14] <LeoBodnar> but it would still condense?
[12:14] <Laurenceb> so the partial pressure is lower
[12:14] <Laurenceb> condensation works off partial pressures
[12:14] <ibanezmatt13> ah right I see, same as I did before but not bother when ignoring things. Got it, thanks
[12:15] <Laurenceb> this is why you can dry things at room temperature
[12:15] <fsphil> yea, since it's not writing into memory it won't matter

[12:17] <ibanezmatt13> if I change the number in front of the % to a 6, it prints a load of rubbish
[12:18] <fsphil> two things
[12:18] <fsphil> you're not checking the value returned by sscanf
[12:18] <fsphil> it's important (will tell you if it actually worked)
[12:18] <fsphil> your 5 is in the wrong place
[12:19] <ibanezmatt13> oh
[12:19] <fsphil> it's telling it the string begins after a character '5'
[12:19] <ibanezmatt13> oh god of course
[12:19] <fsphil> so when you change it to 6
[12:19] <mfa298> C is very good at doing exactly what you tell it to do,
[12:19] <fsphil> it won't find a six, fails and doesn't write anything
[12:19] <LeoBodnar> so butane inside He will always be unsaturated vapour?
[12:19] <ibanezmatt13> ah I see
[12:19] <Laurenceb> yes
[12:19] <fsphil> sscanf() should return the number of fields it processed
[12:20] <fsphil> if it's not what you expect then it's a good bet something is wrong in the string
[12:20] <ibanezmatt13> wouldn't there be a chance of it failing still even checking the return value?
[12:20] <fsphil> totally
[12:20] <Hix> ibanezmatt13 did you d.l the K&R link i sent a while back>
[12:20] <Hix> ?
[12:21] <ibanezmatt13> yes Hix, it was a good read
[12:21] <fsphil> well not fail in terms of sscanf()'s work
[12:21] <Hix> cool - its an invaluable helper
[12:21] <ibanezmatt13> I'm not sure why I must check the return value of sscanfat the moent
[12:21] <ibanezmatt13> moment*
[12:21] <fsphil> because it's good practice
[12:21] <fsphil> you've already hit a bug because you didn't :)
[12:22] <ibanezmatt13> I'm struggling to understand what it actually does though :)
[12:22] <ibanezmatt13> it returns the number of processed fields, I know that bit
[12:22] <ibanezmatt13> I'm not sure how that will avoid the problem
[12:23] <fsphil> your bug earlier caused it not to return anything in altitude

[12:23] <ibanezmatt13> wasn't that due to the misplaced 5 though?
[12:23] <fsphil> yep
[12:23] <fsphil> but that's not the point
[12:24] <fsphil> something in the string caused it not to return all the fields you asked it for
[12:24] <mfa298> ibanezmatt13: you'll find when you start writing good C code you're code will be filled with if statments checking that things worked. Most of the time things will be fine, but occasionally things break and that's what leads to nasty program crashes
[12:24] <ibanezmatt13> yeah, I'd better get this sorted then
[12:24] <ibanezmatt13> So I need an if statement
[12:25] <ibanezmatt13> or more appropriate, a while
[12:25] <fsphil> at least if it returns the expected number of fields, you know there's at least something in all the strings
[12:25] <ibanezmatt13> while the result of sscanf is = number of fields I want, do code - otherwise, reloop ?
[12:26] <fsphil> no point while()'ing, the value of mystring isnt' changing
[12:26] <fsphil> it'll just loop forever
[12:26] <ibanezmatt13> if
[12:26] <fsphil> yep
[12:26] <ibanezmatt13> if what I want, do stuff, otherwise, print fail message & exit
[12:26] <ibanezmatt13> that's a good start
[12:26] <fsphil> *if* sscanf() returns what I expect, then process the values
[12:26] <ibanezmatt13> yep
[12:27] <fsphil> that, and testing the checksum, should be more than enough
[12:27] <ibanezmatt13> in fact
[12:27] <ibanezmatt13> I never bothered checking the checksum in my python code :/
[12:27] <fsphil> many don't
[12:27] <ibanezmatt13> I just read what I wanted up to the altitude
[12:27] <fsphil> it's a direct serial link, errors are not too likely
[12:28] <ibanezmatt13> I guess checking it is just a standard proceedure that I could get from the datasheet
[12:28] <ibanezmatt13> I'll leave that for now
[12:28] <fsphil> it's a simple crc
[12:28] <fsphil> there's plenty of code examples out there for it

[12:29] <ibanezmatt13> I assume not

[12:29] <ibanezmatt13> ok

[12:30] <ibanezmatt13> I've done the if
[12:30] <ibanezmatt13> if x=x { code } not sure where the else goes. Time for a google
[12:30] <fsphil> it's not too bad
[12:34] <ibanezmatt13> fsphil, the code is working but if for instance time comes through as HHMMS as opposed to HHMMSS, it still take the HHMMS and puts it in time. Is this avoidable using sscanf or must I just do that and check later on
[12:34] <fsphil> I don't think a gps module ever would return time like that
[12:34] <fsphil> but it might do hhmmss.ddd

[13:37] <Lunar_LanderU> is that circuit a good idea when using a 3.3V AVR and the MOSFET should switch 12 V?
[13:38] <mattbrejza> logic level can be straight from the uC
[13:38] <DL1SGP> yes see "Logic Level - FET schaltet bei niedrigen Gatespannungen von typisch 4,5V (z. B. CMOS Logikpegel) hinreichend durch. Normale MOSFETs brauchen hierfür typisch 10V."
[13:38] <mattbrejza> unless you have something weird going ob
[13:38] <DL1SGP> http://www.mikrocontroller.net/articles/MOSFET-%C3%9Cbersicht
[13:38] <SpeedEvil> A small - 1Kish - resistor may be a better idea.
[13:38] <Lunar_LanderU> OK, thanks
[13:38] <SpeedEvil> It can avoid wierd oscillations
[13:38] <Lunar_LanderU> ok, 1k in line with the gate?
[13:38] <SpeedEvil> - connected between the GPIO and gate
[13:38] <SpeedEvil> yeah
[13:38] <Lunar_LanderU> ok
[13:39] <mattbrejza> and yea pull down if you dont want it to trigger accidently
[13:39] <Lunar_LanderU> yeah, Datasheet gives V_gs(tresh) to be 0.8 to 2.5 V
[13:39] <Lunar_LanderU> so that should be OK?
[13:39] <SpeedEvil> Lunar_LanderU: IGNORE THAT NUMBER.
[13:39] <Lunar_LanderU> ok
[13:39] <mattbrejza> what you really want is the GS current against gate voltage
[13:39] <mattbrejza> *DS
[13:39] <SpeedEvil> Lunar_LanderU: You do not care about it. You care about the voltage at which Rds is specified at
[13:39] <Lunar_LanderU> OK
[13:39] <SpeedEvil> Vgs(th) is the voltage at which the current is 250uA or so
[13:40] <Lunar_LanderU> ah
[13:40] <mattbrejza> or the Vds Ids one
[13:40] <SpeedEvil> The other fun issue is - don't trust the graphs in the datasheet.
[13:40] <Lunar_LanderU> Diodes Inc. only made a one page sheet without any plots, nice of them
[13:40] <Lunar_LanderU> yeah
[13:40] <Lunar_LanderU> OK, I can see R_ds
[13:40] <SpeedEvil> If they don't specify at what Vgs(th) the specific one is measured at - you can't know exactly how they apply

[13:41] <Lunar_LanderU> 5 Ohms at V_GS = 10 V, I_D=500mA and 7.5 Ohms at V_GS = 5 V, I_D=200 mA
[13:41] <SpeedEvil> If you have a graph of Id vs Vds for a range of gate voltages - fine - you can look along the 5V gate line, and get a single figure.
[13:41] <Lunar_LanderU> yea
[13:41] <Lunar_LanderU> my AVR is 3.3V btw
[13:42] <SpeedEvil> But - if the Vgs(th) is 2.4-4 - that's a 1.6V spread. Now - what voltage is that '5V' line for your FET. It's really a band

[13:43] <Lunar_LanderU> yea
[13:43] <Lunar_LanderU> I have to explain first I think
[13:43] <Lunar_LanderU> that MOSFET is specified in a circuit we were building from a paper
[13:43] <micster> where I can find info about B-17 which landed in Finland?
[13:44] <Lunar_LanderU> and we want to modify it from an OpAmp oscillator controlling the MOSFET gate to the CPU controlling the Gate
[13:44] <SpeedEvil> Select a max rds(on) test voltage of 3.3V

[13:45] <mattbrejza> Lunar_LanderU: btw the device you posted isnt suitable (assuming you want to put a decent current through it)
[13:45] <micster> tnx
[13:45] <Lunar_LanderU> hm
[13:45] <DL1SGP> in case of further questions just ask here and you might get an answer :D
[13:45] <Lunar_LanderU> btw it is the electrometer I am building
[13:45] <Lunar_LanderU> one sec
[13:45] <OH1MN> pe2G: just lost it... dont know if it was the rains that brought the B-17 down fast or what. but if it lifts up agn will be sure to listen for it. RX is still on as with many OHs

[13:47] <mattbrejza> oh that circiut
[13:48] <Lunar_LanderU> yea
[13:48] <mattbrejza> hmm so theres like almost no current going through the GET
[13:48] <mattbrejza> FET
[13:48] <mattbrejza> so id say you just need to make sure the DS resistance is low enough at the voltage you intend to drive it
[13:48] <Lunar_LanderU> yeah
[13:48] <mattbrejza> which still means logic level
[13:49] <mattbrejza> so really it doesnt change anything
[13:49] <Lunar_LanderU> yeah
[13:49] <mattbrejza> it might ahve to be low leakage or something like that
[13:49] <Lunar_LanderU> that is probably why they chose that mosfet
[13:49] <Lunar_LanderU> yea
[13:50] <Lunar_LanderU> main reason for considering that was that the oscillator isn't synchronized with the CPU sampling the data
[13:50] <Lunar_LanderU> my prof said you have to take a reading right after reset and then one after a few seconds of waiting time
[13:52] <tweetBot> @P_Knol: @PA3ARK #UKHAS #HAB B-17 http://t.co/4gJQjOPvsk
[13:55] <Lunar_LanderU> mattbrejza: so direct control via some resistors should be possible?
[13:55] <mattbrejza> i think the idea is that you sample much more offen than it resets, and the resets are obvious when you come to look at the data
[13:56] <Lunar_LanderU> yea

[14:00] <mattbrejza> im sure it can be programmed fine

[15:06] <SpeedEvil> Literally it's spun up on launch, the motor goes on for 5 seconds, then cuts off and flies ballistically.
[15:06] <OH7HJ> If windy, large kites can lift small receivers. If calm, a chain of large plastic trash bags serving as balloons and tied to a line may lift rx, too.
[15:07] <SpeedEvil> yeah - I know - there are probably better solutions.
[15:08] <OH7HJ> For that kind of trajectory a mini rocket would work. Their engines ar available for hobbyists. Ducted fans are far too powerless.
[15:09] <SpeedEvil> and yes - but they have way more regulatory issues.

[17:52] <Benny_boy> One of teh ones suggest on this site
[17:52] <iain_G4SGX> Dom seem very resilient to a carrier QRM in the pass band, not so for a sweeping pulse.
[17:53] <DL1SGP> Benny_boy: did your dvb dongle run for a while before you started your test?
[17:53] <Benny_boy> not particularly
[17:53] <Upu> I've seen those dongles drift
[17:53] <Upu> leave it on for 30 mins then power up the NTX2
[17:53] <Benny_boy> 30 mins! Wow!
[17:53] <Upu> well
[17:53] <Upu> 10
[17:53] <Benny_boy> Okey dokey
[17:54] <LeoBodnar> Yes since it is encoding information in frequency shifts rather than frequency values themselves
[17:54] <Upu> can be cheapy crystals in them
[17:54] <DL1SGP> make sure you use the dongle a while before running the test, the fact that it warms up seems to make it drift. also use a small usb patch to distance it from your fan if the fan for your computer should blow hot air at it
[17:54] <Upu> the NTX2 is unlikely to drift unless you have power supply issues or the temperature is changing rapidly
[17:54] <Benny_boy> ahhhhh. It's just for test purposes anyway
[17:54] <Willdude123> Upu sorry haven't started yet :)

[17:56] <Benny_boy> So how do the tracking stations follow the signals from the NTX2s as they move through the air column? If they're so picky about the temperature, does teh base station just listen of a broad frequency range?
[17:57] <Upu> dl-fldigi can with certain radios automatically compensate for drift
[17:57] <Upu> otherwise its a manual retune job
[17:57] <Benny_boy> Ug
[17:57] <Upu> dl-fldigi can only "see" 3000Hz of spectrum at once anyway
[17:58] <Upu> 6000 even

[19:11] <OH7HJ> If it has, as usual, you will get more gain when balloon is up if replace the level radials with a sigle downward wire. That will make the aerial a vertical dipole.

[19:15] <LeoBodnar> OH7HJ: yes
[19:15] <OH7HJ> To get the aerial radiate where it is needed - towards horizon - the aerial gives a bit better signal if made as dipole instead of GP.
[19:16] <DutchMillbt_> Maxell heb jij last van de QSO's op 26.960?
[19:16] <LeoBodnar> OH7HJ: modelling shows that in open space GP = dipole
[19:16] <Geoff-G8DHE-M> Ahh its 26MHz .... thnks
[19:16] <LeoBodnar> apart from impedance
[19:17] <OH7HJ> Also, if use collinears for 3dB + gains, it is again best to use center fed ones. They radiate towards horizon.

[19:17] <LeoBodnar> OH7HJ: sorry "yes" was for horizontal radials

[19:18] <Maxell> DutchMillbt_: nee, http://i.imgur.com/H4Brbb2.png
[19:18] <OH7HJ> End-fed collinears like the popular commercial ones tend to radiate too high. That means they do not have much gain.
[19:20] <bertrik> LeoBodnar: is B-18 also 10 mW?
[19:20] <LeoBodnar> Earth presence affects radiation pattern a lot. Balloon is pretty much free space antenna
[19:20] <LeoBodnar> yes
[19:20] <OH7HJ> Here is one kind of center fed collinear 2x 5/8 wl for 2 m band. Its driven element made by covering glass fiber rod with aluminum foil tape. http://www.oh7ab.fi/foorumi/viewtopic.php?f=21&t=228
[19:21] <OH7HJ> For pico balloon payload, of course the lightest wire is proper for aerial material of course.
[19:24] <OH7HJ> The aerial of that link is a dual band one, that is why its feed is shown in detail. Single band aerial is still simpler.

[19:29] <OH7HJ> If it is the one ppointing down, you have the better case of radiation direction, because it tends to radiate down. Now listening stations near and behind it get a bit stronger signal.

[19:34] <OH7HJ> Yes, the aircraft style of downwards radiator. However, one gets 1 dB or so more towards horizon where it is needed, by replacing the level radials with a single upright one.
[19:35] <LeoBodnar> OH7HJ: it's downward, there is no upward radials
[19:35] <bertrik> normally, the payload box is in the way for the upright one :)
[19:35] <LeoBodnar> 4 horizontal ones are GP and downward is driven. Thread is just a thread.

[19:43] <HAPPYBASEDGOD> Upu not trolling. just telling you my thoughts
[19:44] <OH7HJ> Yes, the radials have double function. If one prefers to use them, one can make GP lobes point to horizon by bending radials, in this case upright after the solar panels.

[19:48] <Upu> that might be why he just leaves
[19:48] <OH7HJ> Enkidu, the radials are bent after the solar panel fastening points, so they won't be tilted away.
[19:48] <Upu> anyway back on topic
[19:48] <mfa298> ibanezmatt13: unfortunately to kick/ban you need to be an op on the channel as well. Not everyone can do it.
[19:49] <ibanezmatt13> oh
[19:49] <ibanezmatt13> How do people become ops?
[19:49] <jcoxon> with great power comes great responsibility
[19:49] <mfa298> apart from the odd channels I've been on where everyone has had op's (apart from managers when they use irc)
[19:49] <Upu> seems 26Mhz is better that 14Mhz
[19:49] <enkidu> OH7HJ: still it would not really affect radiation pattern, as firts third of radial is essential in GP
[19:49] <Upu> generally you get asked to do it ibanezmatt13, if you want it you're probably not the right person to have it
[19:49] <daveake> :)
[19:49] <ibanezmatt13> good point

[19:51] <OH7HJ> Good question, enkidu! The essential parts of aerial are element tips. The radial angle is measured from feed point to radial tips. It does not really matter if the wires make a curve between.
[19:53] <bertrik> do the GP wires need to be of a certain length, or just "long enough" to work as a ground plane?
[19:53] <enkidu> OH7HJ: I think that we could try using little heavier QFH
[19:53] <ejcspii> LeoBodnar, how long is the fed element?
[19:54] <OH7HJ> Longer than 1/4 wl radials are needed for some special cases only.

[19:57] <mfa298> ibanezmatt13: there's often several ways to do something so part of what makes the right way is to use the method that makes sense to you.
[19:58] <LeoBodnar> ejcspii: 300/freq/4
[19:58] <ibanezmatt13> good point. It does make sense I'll admit but I just didn't know if it worked
[19:58] <mfa298> For arduino I think a lot of people have used the tinygps library as that does some of the work for you.
[19:58] <ejcspii> LeoBodnar: allright, so not shortened, full lambda/4
[19:59] <mfa298> but using libraries like that can give other issues
[19:59] <DL1SGP> at present course B-18 should come audible here in about 3h, fun
[19:59] <ibanezmatt13> I think doing it without libraries such as that would be better for my understanding anyway, just a bit of a trek
[20:00] <mfa298> a lot of people will also stay well away from the scanf set of functions as they've had it beaten into them that they're unsafe. However the way you're using sscanf should be ok
[20:00] <bertrik> DL1SGP: we got the first good decode at about 150 km distance, with a setup that is not optimised at all for 27 MHz
[20:00] <enkidu> so 27mhz now?
[20:00] <ibanezmatt13> what's the most popular way of reading NMEA into C mfa298?
[20:00] <iain_G4SGX> I'm going to leave my RX on overnight, in case of skywave when the sun comes up.
[20:01] <mfa298> well testing it on a computer with native compiler you won't have tinygps anyway so you need to do something yourself to parse it.
[20:01] <DL1SGP> I should be receiving in pretty long tomororw if it stays on predicted course
[20:01] <DL1SGP> bertrik: you can see my tower on the map, north east of Hannover
[20:02] <bertrik> enkidu: well, approximately
[20:02] <mfa298> I don't know what the most popular method is. In my code (not arduino) I'm working through the string looking for commas but seeing what you've done with sscanf I can see that might have been an easier method
[20:02] <ibanezmatt13> mfa298, it was brought to my attention earlier that I should make all the variables char variables. I experimented with int variables but it persistently failed.

[20:06] <mfa298> ibanezmatt13: it should be possible to use things other than a char* but remember you need to pass sscanf the address to the variable to use not the value.
[20:06] <enkidu> my dongle seems in freq range, but I would need a proper antenna
[20:07] <ibanezmatt13> not fully sure what you mean mfa298 about passing value?

[20:08] <DL1SGP> PE2G: 130km/h is suggested speed nationwide in Germany, if you go faster and have an accident then you can get issues with insurance. also large sections of Autobahn now are limited to max. 130km/h +/- jam slowdown

[20:09] <ibanezmatt13> ie, point it to the location of the number varibale?

[20:10] <bertrik> enkidu: we use this https://revspace.nl/images/4/46/KrhFBxL.jpg
[20:10] <mfa298> you'd define it as int number, but when you call sscanf you use &number, then in the printf you just use number again.
[20:10] <ibanezmatt13> and the reason I can't just give it the variable name is because say it had value: 3, it thinks I'm telling it to store it in location 3 and it doesn't know what that is? mfa298
[20:10] <mfa298> in the sscanf you could read it as the address of number
[20:11] <mfa298> pretty much

[20:11] <ibanezmatt13> o
[20:11] <ibanezmatt13> k
[20:11] <mfa298> it's important when calling functions as normally in a function the only way to pass data back is via the return.
[20:11] <ibanezmatt13> does that not apply for strings then?
[20:11] <bertrik> DL1SGP: I think it's a solar heat collector
[20:11] <DL1SGP> ah
[20:11] <mfa298> but you can only pass one item via return
[20:12] <DL1SGP> I have a discone like the one you got, a bit different but well. they work fine
