[00:01] <Lunar_Lander> hello
[00:01] <hibby> cool
[00:01] <hibby> I'm currently designing multiple axial-mode helical arrays to expand our station
[00:01] <Zuph> Evening, Lunar_Lander
[00:02] <Zuph> You're up late.
[00:02] <Lunar_Lander> yeah true
[00:02] <Lunar_Lander> :)
[00:02] <Zuph> hibby: Cool :) Ours weighs about 100g.
[00:02] <Lunar_Lander> I had a headache earlier
[00:02] <Zuph> yuck
[00:02] <hibby> by keeping the wideband characteristics of the individual ones and grouping them, I think I can just about fir the spec for UKube 1, which is a 1Mbit downlink on 2.4GHz
[00:02] <Lunar_Lander> yeah
[00:02] <Lunar_Lander> but I found something I want to show

[09:11] <MNSP> yeah thats all I can find too fsphil
[09:11] <fsphil> the u.fl socket seems to be only available for pcbs
[09:12] <fsphil> you might be able to make one
[09:12] <MNSP> I have the gpsbee and the external antenna
[09:12] <MNSP> ahh, theres a thought....

[09:47] <SpeedEvil> Laurenceb; Solar-thermal thingies arrived. I diddn't realise that theheatpipe is actually at STP.
[09:47] <SpeedEvil> Well - the outside of the heatpupe
[09:47] <Laurenceb> STP?
[09:47] <SpeedEvil> The only bit actually iunder vacuum is the bit inside the thermos.
[09:48] <SpeedEvil> Standard Temperature and PRessure
[09:48] <Laurenceb> ah
[09:48] <SpeedEvil> The OD of the tube is 57mm, the internal is about 40 of the inner tube, with some aluminium to take the heat to the central copper pipe which isn't under vacuum
[09:49] <Laurenceb> so the heatpipes are filled with some sort of refridgerant?
[09:50] <SpeedEvil> I haven't opened that. :)
[09:50] <SpeedEvil> I'd imagine so.
[09:51] <SpeedEvil> It's also a cheap way to buy really long heatpipes.
[09:51] <SpeedEvil> I can't off-hand think of a use for them though

[09:57] <NigeyS> m1x10
[09:57] <NigeyS> yes it will
[09:57] <NigeyS> i use that setup on ATS
[09:57] <NigeyS> youll prolly get between 3.27 and 3.28 you went get bang on 3.3
[09:57] <m1x10> i did not catch you

[09:58] <SpeedEvil> NigeyS: yes.
[09:58] <NigeyS> yey!
[09:58] <SpeedEvil> NigeyS: A nice man in a van arrived, and took a cheque.
[09:58] <NigeyS> off you go, get them hooked up, LAN party at yours :P
[09:58] <SpeedEvil> (serial number 00001)
[09:58] <SpeedEvil> I'mnot feeling that energetic
[09:59] <NigeyS> eugh, i wont even ask how much that cheque was for lol
[09:59] <SpeedEvil> 360 or so
[09:59] <SpeedEvil> For a 18 tube 57mm*1800mm collector
[09:59] <NigeyS> oh.. that's not to bad ?
[09:59] <SpeedEvil> about 1.5m^2 active area
[09:59] <SpeedEvil> not really
[10:00] <NigeyS> will you have just 1, or you going to increase as budget allows ?
[10:00] <SpeedEvil> It's not so much the immediate saving that bothers me - it's the being able to se hot water without thinking of the cost.
[10:00] <SpeedEvil> I'm fairly sure that more than one for water doesn't make sense.
[10:01] <NigeyS> same problem here, thinking about wether or not i can afford to heat the house with gas next winter .. the bills this / last year were shocking
[10:01] <SpeedEvil> And for heating, to heat appreciably in sep/oct feb/mar takes a lot of panels.
[10:01] <SpeedEvil> (Forget about nov dec jan
[10:01] <SpeedEvil> Is it well insulated?
[10:02] <NigeyS> not at all
[10:02] <NigeyS> the attick is, but internal walls .. barely have any render let alone insulation

[10:02] <NigeyS> double glazed, but counter productive without a good wall insulation
[10:02] <SpeedEvil> Double glazing is a piss-take for not properly insulated walls.
[10:03] <SpeedEvil> Well - unless you have way more glass than normal.
[10:03] <NigeyS> exactly... landlord needs a kick up the ass for the shite job he did on this place
[10:03] <NigeyS> and he wants me to buy it .. pffffffff
[10:03] <SpeedEvil> Hmm. You're in wales. Can you just stack loads of sheep up against all the walls?
[10:04] <NigeyS> lol we dont have many sheep in the middle of the city unfortunately :P
[10:04] <SpeedEvil> More seriously - electric blankets++
[10:04] <NigeyS> yup, and extra thick quilts
[10:04] <NigeyS> doesnt help i feel the cold more cause of my illness :(
[10:04] <SpeedEvil> :/
[10:05] <NigeyS> if he would sell this place for 90k id buy it, anything over that .. not worthh it
[10:05] <SpeedEvil> Are you on disability benefits, and can you get your doctor to write ssaying the cold is affecting your condition?
[10:05] <SpeedEvil> If so - you can do the disablef facilities grant for insulation.
[10:05] <SpeedEvil> I guess not.
[10:06] <NigeyS> im on standard E.S.A at the moment, have been on and off that for 6 years while i wait for the NHS to approve my treatment, otherwise i have to go private and pay £3k a time!

[10:09] <SpeedEvil> :/
[10:09] <NigeyS> postcode lottery anyone
[10:09] <SpeedEvil> Indeed.
[10:10] <SpeedEvil> They're also chaning 'crisis loans' - to be run by your local council from non-ringfenced money.
[10:10] <SpeedEvil> Which is a mind-bendingly bad idea.
[10:10] <NigeyS> oh god thats going to go down like a lead balloon!
[10:10] <NigeyS> scuse the pun
[10:12] <NigeyS> im debating getting a loan to get my treatment privately, but part of me says says why should i, ive worked when ive been able to, ive not been a jobless bum etc etc swings and roundabouts
[10:14] <SpeedEvil> Yeah.
[10:14] <SpeedEvil> You've investigated the various avenues to get your trust to reconsider its decision?
[10:14] <SpeedEvil> I vaguely remember that in some cases, they will pay for stuff not recommened by NICE
[10:14] <NigeyS> yep, ive even had my MP write to the trust
[10:15] GeekShadow (~Antoine@reactos/tester/GeekShadow) joined #highaltitude.
[10:15] <NigeyS> the problem is, even if it gets approved, the waiting list will be so massive (3 years at least) it may still be worth it going private just to get back into work before im 40!
[10:16] <GW8RAK> Sounds tough NigeyS
[10:16] <NigeyS> my surgeons well annoyed, she's got me down as the ideal candidate for for it, right age, weight, symptoms etc etc

[10:18] <SpeedEvil> DLA?
[10:18] <GW8RAK> What gets me about all the debates about the NHS are they talk about the NHS as an organisation, doctors, nurses consultants, NICE, managers etc but rarely do they really focus on the patients.
[10:18] <NigeyS> that's only just been sent in, literally last week, fingers crossed!
[10:18] <SpeedEvil> DLA is meant to help with that. You need to fully understant the guidelines though.
[10:18] <SpeedEvil> Sigh.
[10:18] <NigeyS> very strict from what i was reading
[10:19] <NigeyS> GW8RAK, very rarely imo
[10:19] <SpeedEvil> Yes - I've just sent them a 'did you even read my fucking form' letter - after being knocked back for DLA
[10:19] <NigeyS> lol theyre evil people apparently, took them 6 months to decide to even concider me for applying for it
[10:20] <NigeyS> i want to be out working dammit! i keep trying to drum that into the job center muppets but it falls on deaf ears
[10:20] <GW8RAK> I've never had any problems and although some time ago, my wife's treatment was fantastic and quick. Unsucessful, but that was just act of god.
[10:21] <NigeyS> GW8RAK, sorry to hear that :( yaknow, i cant fault my GP's or my surgeons, it just seems this treatment is so caught up in red tape, the patient doesnt count
[10:22] <GW8RAK> I would love to hear a politician say that he/she doesn't care about the NHS, just about the patients. At times, the organistion seems bigger than it's real customers.
[10:22] <GW8RAK> Unfortunately, too many times, politicians are seen as the customers and patients as the raw materials
[10:23] <NigeyS> as would i, but i fear that day will never come, we are no longer patients to them, just numbers, and statistics

[10:29] <NigeyS> thanks speedy i'll take a good long look :D

[10:38] <NigeyS> speaking of morse code, the torch app for my desire hd has a morse code thing so it flashes SOS .. kinda handy

[10:39] <SpeedEvil> :)
[10:40] <GW8RAK> The big advantage of cw is the simplicity of the rig and the high s/n ratio. It seems a contradiction to want that and then add a laptop or similar to what is a simple system
[10:40] <GW8RAK> Unfortunately, so much of the on air cw is poorly sent or just too fast.

[14:08] <SpeedEvil> Coppers thermal conductivity of 400W/mK - that's not a mili.
[14:17] <Laurenceb_> lol
[14:18] <Laurenceb_> hmm solder has cracked around some of the ceramic caps
[14:20] <Laurenceb_> only the 0805 and 1206 caps tho
[14:20] <NigeyS> not enough solder ? .. to much tension when it melted?
[14:20] <Laurenceb_> differential thermal expension thing
[14:20] <Laurenceb_> happened when i reflowed nearby poarts
[14:21] <NigeyS> ohh
[14:25] <eroomde> Laurenceb_: yep if using a toaster oven you need a gntle cooldown phase too

[14:40] <Dan-K2VOL> hey eroomde

[14:42] <Dan-K2VOL> eroomde that must have been zuph I hadn't gotten around to replying yet
[14:42] <fsphil> did the analyser help dan?
[14:42] <Laurenceb_> could stress on a ceramic cap cause it to short out internally?
[14:43] <Dan-K2VOL> but yes fsphil, we used it every step of the build process
[14:43] <Dan-K2VOL> and resulted in an amazing performance, granted we only had 15 mintues to test before a storm came in
[14:43] <Laurenceb_> if there was enough stress on it to crack the solder
[14:44] <Dan-K2VOL> but it was the lowest latency we'd ever seen the sat modem send data
[14:44] <Dan-K2VOL> and picked up satellite lock from a satellite that was ON the horizon, unheard of with the jPole or dipole

[14:50] <eroomde> mmm
[14:50] <eroomde> i'm going to be cautious about it

[14:53] <eroomde> just need said cool project
[14:53] <eroomde> right, bbl
[14:54] <Laurenceb_> hmf this is perplexing
[14:55] <Laurenceb_> all i can think of is that the ceramic cap that cracked the solder has shorted out internally
[14:55] <Laurenceb_> but is that even feasible?
[14:55] <GW8RAK> Is it a smt cap Laurenceb_ ?
[14:56] <Laurenceb_> yes
[14:56] <GW8RAK> If the board is flexed at all, then consider any or all of the caps as being broken internally.
[14:56] <Laurenceb_> i reflowed nearby parts and noticed the solder had cracked at each end
[14:56] <Laurenceb_> ok
[14:56] <Laurenceb_> so thats the most likely thing?
[14:57] <Laurenceb_> its thermal stress
[14:57] <Laurenceb_> well thermally induced mechanical stress

[15:00] <GW8RAK> Reading recently about a smt DDS board, it specificially says that if the board is flexed, just replace all the caps or buy a new board. A very common problem apparently.

[15:01] <Laurenceb_> oh well thats several £ down the drain - stupidly expensive 15uF 35v 1206 ceramic

[15:52] <mattltm> So may be ready tomorrow.
[15:52] <LazyLeopard> Taken a while, then...
[15:52] <mattltm> I'll go with the weekend option..
[15:52] <LazyLeopard> It usually only takes 'til the following Wednesday...

[16:09] <LazyLeopard> Nearest one to me is a 1-pointer http://sotawatch.org/summits.php?summit=G/SE-005
[16:09] <LazyLeopard> Height, mostly.
[16:09] <LazyLeopard> ...but it varies from association to association.
[16:10] <LazyLeopard> If you want to build up scores quickly, go to (or chase) German summits
[16:10] <LazyLeopard> They have plenty of 10-pointers.
[16:11] <fsphil> there's a 6 point one within 25km of here

[16:12] <fsphil> fairly unpronounceable name
[16:13] <LazyLeopard> All the ones in the south east region are 1-pointers.
[16:14] <fsphil> not sure what antenna to try. a 1/4 vertical would be easiest, but from what I've read it wouldn't be the best for uk contacts?
[16:15] <LazyLeopard> I guess you wouldn't get the NVIS contacts with it...

[18:04] <cuddykid> I've just been reading on the wiki that "Payloads should be kept small - just a few hundred grams at most" - does this mean upto ~ 1Kg? Mine weighs in around 700g atm
[18:05] <fsphil> anything under 1kg should be fine
[18:05] <cuddykid> good good
[18:05] <fsphil> just imaging it landing on your head, if you wouldn't like that - then don't launch it :)
[18:06] <BrainDamage> depends on the speed
[18:06] <NigelMoby> If its over 1kg we send Phil over with a hacksaw ;)
[18:06] <fsphil> that's true too
[18:07] <BrainDamage> for instance, I shoot a 0.3g aluminium chunk with my railgun @ ~2.1 km/s
[18:07] <BrainDamage> surely don't want that on top of my head
[18:07] <fsphil> if you manage 2km/s with a balloon, I'll be impressed :)
[18:08] <fsphil> with total parachute failure our first payload dropped at about 6m/s
[18:09] <BrainDamage> yeah, it's a bit hard over long dist but I think a weather balloon launched flechette could get a decent airspeed with small cross section
[18:09] <Dan-K2VOL> is the UK law equivalent to ICAO for payload weights on the Light class?
[18:09] <cuddykid> lol, imagine a payload coming down at 2km/s
[18:10] <fsphil> I don't know what the limit is
[18:10] <NigelMoby> Good question Dan
[18:10] <Dan-K2VOL> and 2km/s is ~ Mach 6
[18:11] <Dan-K2VOL> I would be suitably impressed to see a balloon payload travelling at mach 6 too
[18:11] <BrainDamage> mach 6 is a bit unrealistic, but mach1 could be with suitable shape
[18:12] <eroomde> we got 250 m/s dropping something from a balloon
[18:12] <eroomde> mach 0.8
[18:12] <eroomde> but then we deployed a chute

[19:36] <Upu> it wouldn't work over a certain alititude
[19:36] <Dan-K2VOL> by "nearer than I am" that means my roof is near space too upu :-P
[19:36] <Upu> Dan-K2VOL exactly :)
[19:36] <Dan-K2VOL> thus a useless term
[19:36] <eroomde> Thompson: it would be ok but most of us prefer radios
[19:36] <Upu> Just you wait till I launch my nearer to space mission
[19:36] <eroomde> it's a beter way of doing it
[19:36] <hibby> ISS \o/
[19:36] <eroomde> but if you just want the pictures, sure
[19:37] <Upu> radio module is probably cheaper than a phone *just*
[19:37] <Thompson> Yea I just want the pictures to start with may get into it properly if it's a success
[19:38] <Upu> by the time you've got the GPS talking to a phone its just a small step to make it transmit
[19:39] <Upu> it seems quite scary at first, the radio part but it's really not
[19:39] <eroomde> Thompson: where are you based, geographically?
[19:40] <Thompson> So the radio part will provide real time tracking throughout the whole flight? I'm in S. Wales near Brecon beacons
[19:40] <Upu> Strongly recommend you fit a radio in that case
[19:40] <eroomde> NigeyS: see up
[19:40] <Thompson> Why is that?
[19:41] <NigeyS> eroomde, ?
[19:41] <Upu> there are alot of us with listening locations around the UK , we can all assist in tracking your flight
[19:41] <NigeyS> ahh i see it nm im blind lol
[19:41] <eroomde> NigeyS: wales
[19:42] <NigeyS> finally someone else in s.wales! w00h00
[19:42] <NigeyS> Thompson, you're fairly local to me
[19:42] <Upu> Yeah you're near to NigeyS as well :)
[19:43] <NigeyS> upu i saw about the parachutes, woops!
[19:43] <Upu> yeah I'll fix it
[19:43] <NigeyS> local machinist can sort that fairly easily :D
[19:43] <Upu> yup
[19:43] <Thompson> Yeah that's something else I'm unsure about is how much the payload will drift in ascent and descent...is it best to launch at your 'home' and track it or using the wind information go in the opposite direction so it will return near'ish home
[19:43] <Upu> if they can take my pants up for £5 I'm sure a few bits of string on a parachute shouldn't phase them too much
[19:44] <NigeyS> lol !
[19:44] <hibby> awful lot of you english types talking on this iss pass
[19:44] <Upu> Thompson well firstly you'll need to get a NOTAM (I'll get you a link in a sec)

[19:44] <NigeyS> oh yes, you must get a notam, or you cant fly anything :)
[19:44] <Upu> secondly we have a predictor that lets bang in certain parameters and it tells you whereabouts it's going
[19:45] <Upu> Predictor : http://habhub.org/predict/

[19:45] <Upu> NOTAM : http://ukhas.org.uk/general:restrictions_legality?s[]=notam
[19:46] <Upu> http://ukhas.org.uk && http://habhub.org are great resources
[19:46] <Upu> UKHAS has lots of links to peoples project blogs
[19:46] <Thompson> Is that on the ukhas website? I was playing around with that earlier...worryingly some of the results were dumping it in the sea
[19:46] BrainDamage (BrainDama@78.12.229.36) left #highaltitude ("Leaving.").
[19:46] <Upu> yup thats good you know when NOT to launch :)
[19:48] <Upu> it can be a little overwhelming at first so my advise is break it down, go get an Arduino or microcontroller of your choice, go get some free Maxim Ds1812 temp sensors from the Maxim website and get them working
[19:49] <Upu> then go get a GPS and get that working
[19:49] <Upu> etc

[19:54] <Dan-K2VOL> what are you listening to on ISS, voice or packet?
[19:54] <Thompson_> My rough idea at the moment is to build a box using the housing insulation foam stuff...use a camera with time lapse software and a gps tracker and pack it with insulation...how much would a basic radio system set me back?
[19:54] <hibby> LazyLeopard: Just make a quick axial helix... it's ace

[19:56] <hibby> not as ideal, but I can fire up stuff and you should hear it
[19:56] <fsphil> ooh definitely
[19:57] <fsphil> what software do you use to tx?

[20:12] <Thompson> So does the nxt2 transmit the location from the gps unit or is it just a case of following the beeps it transmits...I'll obviously need something to receive this signal what would I need and what's the cost of that set up?
[20:13] <MNSP> evening all :)
[20:13] fsphil (~phil@2001:8b0:34:1:21f:c6ff:fe44:b25b) joined #highaltitude.
[20:15] <hibby> Thompson: Generally we transmit telemetry strings using the ntx2 from data gathered by sensors (gps/temperature/etc) on the balloon
[20:16] <hibby> most folks, myself included, use a mode called rtty, or radio teletype, which is fairly well documented in most of our projects if you're willing to read the code
[20:18] <hibby> all the processing is done onboard by some microcontroller/microcomputer, and on the ground side we tend to use some sort of portable radio (A yaesu ft-817 in our portable experiments or an ic910 in my satellite station) connected to a computer running the UKHAS custom version DL-Fldigi which will quite happily recieve and decode rtty.
[20:18] SpeedEvil (~user@tor/regular/SpeedEvil) joined #highaltitude.
[20:19] <hibby> on the rx side, you can probably cut it down to ~ £100 using chinese import radios (wouxun/puxing) and some sort of homebrew directional antenna
[20:19] <hibby> as opposed to my £20k satellite station or the £500ish ft-817
[20:19] <fsphil> though if you have £20k ...
[20:20] <MNSP> lol
[20:20] <hibby> heheh... Thanks, taxpayer ;)

[20:22] <Thompson> Suddenly becoming a committed hobby and not as easy as I first thought...but sounds really good just need to get to grips with it all i think
[20:23] <MNSP> you and me both Thompson ;)
[20:23] <hibby> the other option is that we all tend to listen to most launches, and depending on where you launch from there's plenty possibility of support/assistance from one of us
[20:24] <hibby> but aye, sending something to near-space isn't particularly easy :p
[20:24] <MNSP> otherwise we'd all be doing it
[20:24] <MNSP> oh hang on...
[20:25] <Thompson> Well the article made it seem easy just a balloon and box with a camera and gps tracker hahah
[20:25] <hibby> Thompson: that's all it is!
[20:25] <Dan-K2VOL> well, you could also just use a findmespot
[20:25] <Dan-K2VOL> and a go-pro HD cam
[20:25] <Dan-K2VOL> and you'd have what you said
[20:26] <MNSP> guess its the how much money vs effort balance
[20:27] <MNSP> although a go pro and findme wont set you back too much
[20:27] Action: MNSP would love a go-pro
[20:27] <hibby> should sign up for the daily contest on their website to win everything they make

[20:52] <MNSP> are they the 'competition'?
[20:53] <Dan-K2VOL> well, of the sporting kind, to us, yes

[20:55] <Dan-K2VOL> arhab.org
[20:55] <Dan-K2VOL> tracks records for anyone who cares to submit proof
[20:56] <MNSP> I get the distinct impression habbing is bigger in the states
[20:57] <Dan-K2VOL> it used to track about 200 launch announcements a year up to 2009 for US amateur launches
[20:57] <Dan-K2VOL> I think it's probably about as popular per capita
[20:57] <MNSP> yeah its the numbers
[20:57] <Dan-K2VOL> but it's easier to get ahold of balloons here, and the rules are more relaxed, so it may happen more, I'm not sure
[20:58] <MNSP> would be interesting if the chinese got a taste for it ;)
[20:58] <Dan-K2VOL> ha probably too much freedom

[21:35] <Upu> I can
[21:35] <mattltm> He is going to have a go at sending back..
[21:36] <NigeyS> wonder if its a FF issue
[21:36] <LazyLeopard> Hmmm... Too many different format options...
[21:36] <Upu> I'll give it a shot if you tell me what to do
[21:36] <mattltm> fsphil: You ready??
[21:36] <mattltm> Upu: you want to send some SSTV?
[21:36] <Upu> I have no idea how too
[21:37] <fsphil> at home -- getting mic, then running back down
[21:37] <mattltm> Upu: Are you licenced?
[21:37] <fsphil> battery in laptop is getting low so needs be quick
[21:37] <Upu> yep
[21:37] <Upu> 2E0UPU
[21:37] <mattltm> Cool. Download MMSSTV
[21:37] <fsphil> I'm not sure how I'm gonna power the atu either
[21:37] <fsphil> I'll try without
[21:38] <Upu> ok got it
[21:38] <mattltm> Install..
[21:38] <Upu> done
[21:39] <mattltm> fsphil: I have QRM on 7171 now.
[21:39] <mattltm> configure..
[21:39] Action: LazyLeopard wonders how many different analogue sstv formats there are...
[21:39] <mattltm> Lots!
[21:39] <mattltm> MMSSTV has 9
[21:40] <fsphil|m> back once again
[21:40] <mattltm> No, it has 43!
[21:40] <mattltm> lol.
[21:40] <fsphil|m> mattltm, I hear voice on that freq
[21:40] <fsphil|m> right click on a mode, you'll see loads more :)
[21:40] <mattltm> 7040?
[21:41] <mattltm> Clear here
[21:41] <fsphil|m> here too
[21:41] <fsphil|m> lemme see if my swr is bad
[21:42] <fsphil|m> urg it's awful
[21:42] <Upu> ok I have a picture
[21:42] <Lunar_Lander> hi fsphil Upu NigeyS g
[21:42] <LazyLeopard> This program has 7 classes, and each class has half a dozen (or so) different variants...
[21:42] <mattltm> lol.
[21:42] <fsphil|m> hiya Lunar_Lander
[21:42] <fsphil|m> I can't TX on that freq
[21:42] <mattltm> Loads of modes.
[21:42] <fsphil|m> lemme try another bad
[21:42] <fsphil|m> band*
[21:42] <mattltm> OK.
[21:42] <mattltm> Upu: you ready to tx?
[21:42] <NigeyS> hey lunar
[21:42] <fsphil|m> no it's awful on all frequencies :)
[21:43] <Upu> I think so how do I do it ?
[21:43] <fsphil|m> ooh what freq?
[21:43] <mattltm> load the image, hit tx.
[21:43] <mattltm> 7040
[21:43] <Upu> sorry to be thick but where does it TX too ?
[21:43] <Upu> do I just key up the mike in front of the speaker ?
[21:43] <mattltm> Oh, do you have an audio interface for your radio?
[21:43] <fsphil|m> USB?
[21:44] <fsphil|m> I hear one
[21:44] <mattltm> USB
[21:44] <Upu> err I have a USB cable but it just does serial and an audio cable from the radio to the PC
[21:44] <fsphil|m> scottie dx
[21:45] <fsphil|m> yay m6mdp
[21:45] <fsphil|m> this is really neat
[21:45] <fsphil|m> mars rover?
[21:45] <mattltm> Yay!
[21:46] <mattltm> Upu, PC -> audio out -> radio
[21:46] <fsphil|m> it sounds pretty clear
[21:46] <fsphil|m> what power are you using?
[21:46] <fsphil|m> laptop battery very low
[21:46] <Upu> wheres it go into the radio Mattlm ?
[21:46] <Upu> 817
[21:47] <mattltm> 10W into a homebrew doublet (50 foot long) and SGC 211 ATU at 15M AGL
[21:47] <fsphil|m> I've got a jack cable between the 817's headphone socket and the pc's line-in
[21:47] <Upu> yeah I have that
[21:48] <fsphil|m> if the OS is setup with the line-in as the audio source, then mmsstv should hear and pick up the image automaticallhy
[21:48] <Upu> my antenna only does 2m/70cms
[21:48] <fsphil|m> aah
[21:48] <fsphil|m> you'll hear nothing with the diamond
[21:48] <mattltm> That will be the problem then :)
[21:48] <mattltm> fsphil: get it?
[21:48] <fsphil|m> it has a good filter for non 70cm-2m bands
[21:48] <fsphil|m> yea
[21:48] <fsphil|m> uploading
[21:49] <Upu> what frequency are you on ?
[21:49] <mattltm> 7.040
[21:49] <Upu> ah yeah
[21:49] <fsphil|m> http://i.imgur.com/Uy0Hu.jpg
[21:50] <mattltm> Yay. The rover lives..
[21:50] <fsphil|m> bit noisy, but again that's just because of where I'm at
[21:50] <mattltm> Ok. one more from me then I got to go sleepy.
[21:50] <fsphil|m> okie
