[03:14] <WB8ELK> SpaceJam flight tomorrow in Rantoul, Illinois north of Champaign IL
[03:14] <WB8ELK> At 1200 UTC
[03:14] <WB8ELK> 28.221 MHz USB
[03:14] <WB8ELK> 147.48 MHZ SSTV Scottie2 mode
[03:16] <WB8ELK> WB9SA-11 or W9YJ-11 on APRS I'm not sure which they'll be using on APRS
[03:17] <WB8ELK> They will be on 144.99 on APRS by the way
[03:20] <WB8ELK> heathkid...what part of Indiana....we just did a flight earlier today (WB8ELK-11) from Columbus, Indiana
[03:23] <WB8ELK> Heathkid...the launch is at the Ranoul AFB museum runway at the Boy Scout SpaceJam event. You're welcome to come out and watch the fun. At 7 am CDT Saturday
[03:23] <WB8ELK> Rantoul, Illinois AFB
[03:26] <heathkid> I'm in Crawfordsville
[03:26] <heathkid> work in Indy
[03:26] <heathkid> used to race SCCA Autocross in Columbus
[03:27] <heathkid> 144.99?
[03:27] <WB8ELK> wow....not very far from Rantoul then...you are welcome to head out to the balloon launch at Rantoul. I won't be there but a number of hams will be chasing and tracking and you might be able to chase with them after the launch. Landing zone is not far from you actually
[03:27] <heathkid> sweet!!!
[03:27] <WB8ELK> Had a great friend Emmett who lived in Crawfordsville
[03:27] <heathkid> I'll watch!
[03:29] <WB8ELK> SSTV images will be sent down on 147.48 MHz....APRS on 144.99 and then will be I-Gated to the APRS maps
[03:32] <WB8ELK> landing zone is predicted to be in the Rockville, Indiana area just to your southwest.
[03:32] <heathkid> nice!
[03:32] <WB8ELK> My friend Emmett used to live in Veedersburg
[03:33] <WB8ELK> hopefully it will land in your yard

[03:38] <heathkid> sweet
[03:38] <heathkid> lower power
[03:39] <heathkid> nice!
[03:39] <WB8ELK> takes longer to lock up than my Trimble Copericus GPS but much lower power
[03:39] <heathkid> yep
[03:39] <heathkid> with the 6 I get a cold start lock in less than 20 seconds
[03:39] <WB8ELK> Flew one on 42 party balloons a few weeks ago from Cincinnati, Ohio
[03:39] <heathkid> Dayton?
[03:40] <heathkid> hamvention?
[03:40] <WB8ELK> no...4th of July.....I usually fly a balloon at the Dayton Hamvention each year but winds didn't cooperate this year
[03:40] <heathkid> ah
[03:40] <heathkid> I was planning a launch from there this year but wasn't able to attend
[03:41] <WB8ELK> I hold a BalloonSat Forum at Dayton...usually on Friday....then we fly a balloon from the Flea Market
[03:41] <heathkid> no, I haven't done a launch yet...
[03:41] <heathkid> nice
[03:41] <WB8ELK> What processor are you using for your APRS board....and transmitter section?
[03:41] <heathkid> 328
[03:42] <heathkid> plus HX-1
[03:42] <WB8ELK> Yes....did you bias the audio in on the HX-1?
[03:42] <heathkid> running very modified trackuino code
[03:42] <heathkid> ?
[03:43] <nigelvh> The trackuino code does some center biasing anyway.
[03:43] <heathkid> I didn't design the entire board
[03:43] <nigelvh> So in likelyhood, the answer is yes.
[03:43] <heathkid> probably
[03:43] <heathkid> :)
[03:43] <heathkid> it just works
[03:43] <WB8ELK> I've put together boards with the HX-1 as well....basically put a blocking cap on the audio input to the HX-1 and then use a pot or voltage divider to bias it up to about a volt or so.
[03:43] <heathkid> and works very well
[03:44] <heathkid> I just need Helium...
[03:44] <WB8ELK> yep....I can hit digipeaters 30 miles away with my payload sitting on my kitchen table during testing...but I do live on a mountaintop so that helps.
[03:44] <heathkid> but have been working on a much smaller pico package
[03:44] <heathkid> :)
[03:45] <heathkid> I live 8 miles southwest of the middle of nowhere in a valley
[03:45] <WB8ELK> Hydrogen is not bad to work with....and a whole lot cheaper
[03:45] <heathkid> sucks to be me
[03:45] <nigelvh> WB8ELK, you said you were using a cypress chip to generate the RF?
[03:45] <WB8ELK> CY22393 with a VCXO as the reference
[03:45] <nigelvh> Power output?
[03:45] <heathkid> I don't like things that can go boom
[03:45] <WB8ELK> about 20 mW
[03:45] <nigelvh> Interesting.
[03:46] <nigelvh> Carry on.
[03:46] <heathkid> well... I do actually... but not when I'm not expecting them to!
[03:46] <WB8ELK> it can go from 3 MHz to 160 MHz
[03:46] <nigelvh> I just finished my next board revision to use an SI4464
[03:46] <WB8ELK> I use the same chipset for my HF balloon transmitters....I have one on 20m WSPR at the moment running 200 mW with a class-E amp with a 2N7000
[03:46] <nigelvh> http://digitalnigel.com/wordpress/wp-content/uploads/2013/07/Board1.png
[03:47] <nigelvh> Did you use a reference for your class-E hf amp? I've been thinking about making one for wspr as well.
[03:47] <WB8ELK> If you look at WB8ELK on 20m WSPR via wsprnet.org you'll see my transmitter in a few minutes....I had it off for testing but will put it back on now.
[03:48] <WB8ELK> Lots of folks in the UK pick my 200 mW signal up on WSPR and Australia late at night as well
[03:48] <heathkid> you're doing 20m HAB testing???
[03:48] <WB8ELK> Yep...I feed the output from my Cypress synthesizer into a 2N7000 FET....get up to 1 watt out of it on 20m.....I use a heatsink on it to do that however.
[03:49] <heathkid> I bet!
[03:49] <WB8ELK> I've flown a lot of 20m balloon flights actually
[03:49] trelane (~trelane@unaffiliated/trelane) joined #highaltitude.
[03:49] <WB8ELK> and 40m, 30m and 10m as well
[03:49] <nigelvh> Did you use a reference design? Or something you came up with yourself?
[03:49] <WB8ELK> came up with it myself
[03:50] <nigelvh> Dunno if you have a blog or a page for your projects, but I'd love to see if you'd share.
[03:50] <nigelvh> I've been fiddling with trying to make a little something with some 2n2222s
[03:53] <WB8ELK> Sure...I haven't posted the schematic as yet...but can email it to you if you want to send me your email via private msg here.
[03:54] <nigelvh> You've got a message.
[03:54] <WB8ELK> Got it....I'll try to turn it into something readable.
[03:55] <WB8ELK> I just turned on my WSPR transmitter on 20m.....it just started transmitting at the moment so in a few minutes the reports should be visible on WSPRNET.ORG
[03:55] <nigelvh> Much appreciated.
[03:55] <WB8ELK> Should be getting into Europe well this time of night
[03:59] <WB8ELK> Nice....my first reports powering up on WSPR are from Hawaii, Alaska, Denmark and Norway
[03:59] <WB8ELK> so looks like 20m is doing well tonight
[03:59] <nigelvh> Got some excellent reports
[04:00] <WB8ELK> Been working on the very complicated code to make it work as a WSPR balloon transmitter.....but very limited in what it can send...just a six-digit grid square and takes two transmissions to do that even.
[04:01] <WB8ELK> but the plus side is that a very weak signal can be heard around the World and lots and lots of ground stations always listening.
[04:01] <nigelvh> Yeah, I've got code to do a normal four digit locator from one of my flight boards.
[04:02] <WB8ELK> But that doesn't narrow things down very well....the complicated part is doing the 6-digit locator and hash code stuff.
[04:03] <nigelvh> Yeah, the locators aren't terribly specific.
[04:03] <WB8ELK> If I run the board at 5 volts I get 200 mW output....at 9 volts I get about 600 mW
[04:03] <WB8ELK> At least with 6-digit Grid Square you get within a 2.5 x 5.0 mile area
[04:03] <WB8ELK> close enough to DF the transmitter
[04:03] <nigelvh> Yeah
[04:04] <WB8ELK> I've been working on code to uplink my Iridium payload to APRS.FI.....but I'd also like to send the position reports to Spacenear?...any idea on how to do that....in earlier versions of Spacenear I just sent an HTTP command to do that
[04:05] <nigelvh> I haven't touched spacenear at all, so honestly I couldn't tell you.
[04:05] <WB8ELK> I was working with the Si4464 as well...but kinda put it on the back burner since the chip is so hard to come by.
[04:05] <WB8ELK> at least here in the US it is hard to get
[04:06] <nigelvh> Yeah, it does seem to come in and out of stock. I managed to catch digikey when they had some in stock and got 5.
[04:06] <nigelvh> Enough to last me a little while at least.
[04:06] <WB8ELK> yep...I only have one and don't want to risk it on a flight
[04:09] <WB8ELK> I'll have to clean up my class-E amp circuit for you....I'll try to do that this weekend and will email you.
[04:10] <nigelvh> It's much appreciated. I need to spend some time with LTspice and see what I can come up with, but I'd love to see your reference.
[04:12] <WB8ELK> Look at the private message for comment on your board Nigel
[04:18] <WB8ELK> bye for now....heading off to bed so I can get up early enough for the SpaceJam balloon

[05:31] <KT5TK-7> I want to spare my last two ones for our big BLT34
[05:31] <nigelvh> Yeah, also considering it's just a foil, it shouldn't be an issue.
[05:32] <nigelvh> Are you still turning it on and off between transmissions?

[05:36] <nigelvh> I'm curious if you have the GPS junk data on this flight.
[05:36] <nigelvh> You've got two changed variables, GPS type, and not controlling the power.
[05:45] <KT5TK-7> Well, the software is still running the same code, but there is no second regulator on the PCB that will be switched on
[05:46] <KT5TK-7> The GPS is directly powered by the primary regulator
[05:50] <nigelvh> Yes, so since it's not switching, then that's something that's changed if things end up not having those odd points.

[09:06] <DrLuke> make it yourself

[13:33] <rogerponts> Hi, what dongle would recommend me ?
[13:33] <KT5TK-7> They are cheap though. They cost $10 each. Including Helium.
[13:35] <rogerponts> to track a HAB what USB-dongle would you recommend me ?
[13:37] <mfa298> rogerponts: if you want a cheap option any of the rtl-sdr dongles should work (E4000 or R820T tuner)
[13:37] <mfa298> if you want something better (but more expensive) get the funcube dongle Pro+
[13:39] <rogerponts> ok thanks
[13:40] <mfa298> if you go down the rtl-sdr route you may also want the habamp to add some filtering and boost the signal

[13:41] <rogerponts> https://www.cosycave.co.uk/product.php?id_product=288 this one could be bought on another web with credit card (not paypal) ?
[13:42] <mfa298> cosycave or ebay tend to be the places to get them
[13:43] <mikestir> i've got a couple of the cosycave R820T ones. they seem ok
[13:43] <rogerponts> yes but in cosycave only accept paypal
[13:43] <rogerponts> and I prefer credit card
[13:44] <mfa298> I think with paypal you can just put credit card details in without creating an account
[13:44] <mikestir> yes I thought that as well
[13:44] <rogerponts> so is like paying with credit card no ?

[16:09] <mfa298> cm13g09: I'm here
[16:10] <chrisstubbs> ibanezmatt13, i use cocktail sticks
[16:10] <chrisstubbs> and just push them in to make holes
[16:10] <chrisstubbs> not as neat :)
[16:11] <ibanezmatt13> cool, sewing pins were the only thing close to cocktail sticks :)
[16:11] <ibanezmatt13> And the stump on the end wasn't good so we shoved some paint on it
[16:12] <ibanezmatt13> Tomorrow is the big one. We're using my Granddad's 1953 router to cut the compartments out :/
[16:12] <chrisstubbs> Lol
[16:12] <SpeedEvil> A router will make a heroic amount of mess.
[16:13] <SpeedEvil> I would not.
[16:13] <chrisstubbs> a bit havy duty for foam
[16:13] <ibanezmatt13> I'm under orders I'm afriad, that's exactly what I said
[16:13] <chrisstubbs> however foam is a good meduim for practicing cnc milling

[16:13] <ibanezmatt13> water?
[16:13] <SpeedEvil> Even if you accidentally go sideways :)
[16:14] <SpeedEvil> Water - to kill the static charge on the polystyrene - it makes cleanup possible
[16:14] <ibanezmatt13> Ah ok
[16:14] <chrisstubbs> SpeedEvil, thats the one, when it plundges into the material with the spindle off ;)
[16:14] <ibanezmatt13> Well, I have a drill and a stanley knife but that's it. My Dad seems to think the router is the most accurate :/ God help me
[16:15] <chrisstubbs> Got a new wifi IP cam in the post today, worked for about an hour and now the power supplies gone :L
[16:16] <SpeedEvil> https://www.youtube.com/watch?v=PDPrFJazD3Q - pantorouter. Kinda awesome
[16:16] <ibanezmatt13> Aside from a hot wire cutter, what would you recommend for carefully cutting recesses to a certain depth? https://www.dropbox.com/s/iusjyafbvem6fee/photo%20%282%29.JPG
[16:16] <SpeedEvil> ibanezmatt13: I'd say use a relatively small drillbit like a router at slow speed.
[16:17] <ibanezmatt13> The router is a bad idea? Just a drill with a suitable drill bit then.
[16:17] <SpeedEvil> Play with a bit of polystyrene
[16:17] <ibanezmatt13> Yeah, thankfully I have quite a bit spare
[16:17] <SpeedEvil> It's not a bad idea as such. It will just make a truly astounding amount of mess.
[16:18] <SpeedEvil> Also - you will need to protect the top surface - the polystyrene is not strong enough to run a router across
[16:18] <eroomde> router is good for polystyrene
[16:18] <ibanezmatt13> We're using it in my Granddad's garage which has a huge vaccum and extractor
[16:18] <ibanezmatt13> How shall I do that SpeedEvil ?
[16:19] <SpeedEvil> Put a bit of wood over the top
[16:19] <ibanezmatt13> Good thinking, I'll mention it to my Dad later and see what he says. Thanks :)
[16:20] <ibanezmatt13> By the way, has anybody got any experience in either writing to an SD card from an AVR, or, using a serial camera with an AVR?
[16:20] <ibanezmatt13> I have a nice project in mind and I just wondered whether it would be beyond my capability
[16:21] <SpeedEvil> What?
[16:21] <eroomde> sd card is easy enough
[16:21] <eroomde> camera depends on the camera
[16:21] <SpeedEvil> filesystem is possibly harder.
[16:22] <mclane> I use a small dremel router for that ibanezmatt13
[16:22] <bertrik> ibanezmatt13: on habanero2 we did sd card, I'll look up the hardware we used
[16:22] <ibanezmatt13> Thanks bertrik :)
[16:22] <ibanezmatt13> mclane: My granddad's is huge and very heavy duty relatively
[16:22] <ibanezmatt13> I think I could manage SD, the camera might be a bit of a push
[16:23] <mclane> ibanezmatt13: what camera?
[16:23] <ibanezmatt13> I'm thinking of seeing what I can do with a serial camera with a microcontroller of some sort, like an AVR or something
[16:23] <SpeedEvil> What serial camera
[16:23] <SpeedEvil> They are moderately rare.
[16:23] <ibanezmatt13> Don't know, I've seen a few
[16:24] <SpeedEvil> You can't use any conventional mobile cameras
[16:24] <ibanezmatt13> Basically, I'd like to be able to record video onto an SD card shared by what an AVR was writing GPS data to
[16:24] <SpeedEvil> Video is unlikely
[16:24] <chrisstubbs> I was looking at some VERY cheap ones on aliexpress the other week. However i expect they would come with crappy documentation. and come to think of it i cant remember if they even did the hardware jpeg encoding
[16:25] <ibanezmatt13> Yeah, I'll probably keep the camera thing separate thinking about it
[16:25] <mclane> I have a linksprite but serial link is too slow for video; only still pictures
[16:26] <ibanezmatt13> I'm making a sort of IMU for my bike. GPS, accelerometer, temp, humidity etc... all being parsed and written to an SD by an AVR. The cam would have been nice but that could be separate I guess :)
[16:26] <ibanezmatt13> I suppose pictures would be fine actually :)
[16:27] <ibanezmatt13> So writing data to an SD would just be some sort of serial interface I guess
[16:28] <mclane> for sd cards use spi
[16:28] <bertrik> ibanezmatt13: we used this board http://www.seeedstudio.com/wiki/Seeeduino_Stalker_v1.0 , the page has an example of logging data. Not an original arduino, but compatible.
[16:29] <ibanezmatt13> thanks, I'll take a look

[17:24] <craag> Lunar_Lander: Great names!
[17:24] <Lunar_Lander> thanks :)
[17:24] <Lunar_Lander> and there is room for a payload class inbetween
[17:24] <Lunar_Lander> who wants to guess that name?
[17:24] <Lunar_Lander> :)
[17:24] <craag> hehe
[17:27] <cm13g09> chrisstubbs: congrats

[17:27] <craag> chrisstubbs: A very complimentary article!
[17:27] <Lunar_Lander> cool!
[17:27] <chrisstubbs> They didnt mention my backup tracker went tits up
[17:27] <Lunar_Lander> xD
[17:28] <craag> That's why it's a backup :P
[17:29] <cm13g09> chrisstubbs: my parents saw the article...
[17:30] <cm13g09> didn't realise I knew some of the people involved (if only by IRC)
[17:30] <chrisstubbs> Lol
[17:30] <chrisstubbs> get cracking building a tracker and me, you and matt can do a H2 launch some time
[17:30] <cm13g09> hehe
[17:31] Action: cm13g09 gulps as the cost of his next project lands in his inbox
[17:31] <chrisstubbs> Can someone give me a pointer in eagle, trying to seperate 2 ground planes but have them interconnected by thermals
[17:31] <eroomde> hab project?
[17:31] <cm13g09> eroomde: sadly not
[17:31] <cm13g09> work
[17:32] <eroomde> chrisstubbs: that's tricky. you can play with the polygon ranks
[17:33] <eroomde> cm13g09: whatcha working on?
[17:33] <cm13g09> eroomde: paintball scoring systems....
[17:33] <chrisstubbs> eroomde, I have the big board ground ranked 2 and the small ground polygon ranked 1: http://imgur.com/HN7tWMq
[17:33] <cm13g09> (of all things!)
[17:33] <chrisstubbs> they just merge together
[17:34] <eroomde> cm13g09: interesting!
[17:34] <cm13g09> eroomde: yes, you could say that... I'd prefer to be playing paintball, than building and maintaining scoreboards for it though ;)

[17:37] <cm13g09> that was close
[17:37] <cm13g09> nearly had an accident with Farnell and order multiples
[17:37] <eroomde> paintball exploded?
[17:37] <eroomde> bought a reel?
[17:37] <eroomde> i'm so pleased they warn you about that now
[17:37] <cm13g09> nope...
[17:37] <cm13g09> my bill-of-materials script
[17:38] <cm13g09> failed to pick up a pack size of 17

[17:39] <Lunar_Lander> also my HIH-5031 seems to work after soldering it to the old breakout PCB
[17:39] <Lunar_Lander> it reacts to breathing and covering the sensor with my fingertip
[17:39] <Lunar_Lander> but it only goes to some 620 bits
[17:40] <Lunar_Lander> maybe it has to settle a bit more after soldering
[17:40] <Lunar_Lander> or that is because it is filtered
[17:40] <Reactive_> hi, is there anyone around who can help me figure out sdr-radio with my funcube+?
[17:40] <Reactive_> i'm not sure im using it properly
[17:40] <Lunar_Lander> (what I mean is, the old HIH-4030 could be brought to max.reading if you put your finger on the sensor)
[17:40] mclane (~uli@pD9E852CF.dip0.t-ipconnect.de) left irc: Quit: Verlassend
[17:40] <SpeedEvil> Reactive_: How does this make you feel?
[17:40] <Reactive_> SpeedEvil: pretty crappy
[17:41] <mfa298> Reactive_: make sure you followed the instructions that came with the FCD
[17:41] <Reactive_> i bought everything I need and I can't get what i'm looking for :/
[17:41] <Reactive_> i read the sdr-radio doc for the funcube, but it's interface isn't the same as v2
[17:41] <mfa298> it's worth trying to receive strong local signals with it first as a test (local FM, air traffic, marine band etc)
[17:42] <Reactive_> actually, i just installed my antenna today so I just wanted to make sure i'm getting proper signals
[17:42] <mfa298> ah sorry you're using sdr radio rather than sdr# in that case there aren't so many instructions.
[17:42] <Reactive_> mfa298: i tried tuning into my local fm station, which worked fine, but there was alot of noise
[17:42] <Reactive_> but strong and loud
[17:42] <mfa298> sdr-radio isn't too bad but you have to get used to the interface
[17:42] <Lunar_Lander> I would expect abouit 850 bits at 100% RH
[17:42] <Lunar_Lander> *about
[17:43] <mfa298> for local radio you'll probably need to increase the vfo bandwidth
[17:43] <Lunar_Lander> as the datasheet says that V_out(100%) = 2.7 V
[17:43] <Reactive_> i'm using a 2m/70cm diamond antenna
[17:43] <Reactive_> mfa298: see, that doesn't mean much to me :(
[17:43] <Reactive_> i really dont know what i'm doing I guess
[17:44] <mfa298> for local FM stations you want to select FM Broadcast in the Frequency Explorer
[17:44] <Reactive_> oh, I thought it was wide?
[17:44] <Reactive_> i got a better signal on wide?
[17:44] <Reactive_> or clearer rather
[17:45] <mfa298> probably won't make much difference
[17:45] <Reactive_> oh
[17:45] <mfa298> you'll probably need to incrase the vfo bandwidth which you can do by dragging the outer band markings in the vfo display
[17:46] <Reactive_> let me try quick

[17:50] <Reactive_> alright
[17:51] <Reactive_> so the problem i think is that the listening level on the funcube might be too high
[17:51] <Reactive_> sounds hectically distorted
[17:51] <Reactive_> if i set it down from 100 to 1 in sound configuration, its clearer, but i think its still way too high
[17:52] <Reactive_> and also the gain reading under frequency goes down from -30dB to -71dB
[17:52] <Reactive_> how do i lower it further
[17:52] <Reactive_> ?
[17:53] <mfa298> not sure. I've never had an issue with the RF gain
[17:53] <mfa298> There's an audio volume control on each vfo in sdr-radio
[17:54] Joel_re (~jr@115.69.254.126) joined #highaltitude.
[17:54] <craag> I'm wondering if you might do better with a simpler interface like sdr# until you've mastered the basics.
[17:54] <Reactive_> i think so
[17:54] <mfa298> that might be true
[17:54] <Reactive_> i downloaded it, lets try
[17:55] <craag> (I still use sdr# because I haven't learnt to use sdr radio yet)
[17:55] <mfa298> with sdr# remember to tick the swap i/Q button
[17:55] <Reactive_> yeah
[17:55] <craag> and set ppm correction to 0
[17:55] <craag> in the 'Configure' button popup
[17:55] <Reactive_> ok hold that thought
[17:55] <Reactive_> can you walk me through it? :)
[17:56] <craag> np
[17:56] <craag> you started it up?
[17:56] <Reactive_> err,i thought i downloaded it, but it seems like it's a console downloader
[17:56] <craag> Yep, run that
[17:56] <Reactive_> like a web installer
[17:56] <craag> It'll download the latest
[17:56] <Reactive_> ah done
[17:56] <Reactive_> okay
[17:57] <Reactive_> up and running
[17:57] <craag> So open it up, select Funcube Pro+ from the dropdown
[17:57] <Reactive_> done
[17:57] <craag> Now click the configure button
[17:57] <Reactive_> ok
[17:57] <craag> a popup will come up
[17:58] <craag> there's a value called 'ppm correction' which is set to -160 iirc
[17:58] <craag> set it to 0
[17:58] <Reactive_> done
[17:58] <craag> Cool, close that
[17:58] <craag> Now tick swap i/q on the left
[17:58] <Lunar_Lander> back
[17:58] <Reactive_> done
[17:59] <craag> Then you're all set up. So click 'Start' and start tuning!
[17:59] <Reactive_> i did
[17:59] <Reactive_> but its still really distorted?
[17:59] <craag> WFM, and with it over the full width of the signal?
[17:59] <craag> I think you can drag it wider as well
[17:59] <Reactive_> oh my god

[17:59] <Reactive_> sorry it was set on AM
[18:00] <Reactive_> and it sounds excellent
[18:00] <Reactive_> thanks a TON
[18:00] <craag> no worries, so many settings, I often leave something misconfigured :)
[18:00] <Reactive_> right
[18:01] <Reactive_> so the next thing i'd like to do
[18:02] <Reactive_> is find out if its possible to hear aircraft messages?
[18:02] <craag> Yep
[18:02] <Reactive_> are they AM?
[18:02] <craag> They are
[18:02] <craag> Can't remember what freq though
[18:02] <mfa298> around 118 -120 MHz I think
[18:02] <Reactive_> the local radio supplier here said in south africa its around 80 - 100
[18:03] <Reactive_> are they all the same?
[18:03] <Reactive_> worldwide?
[18:03] <craag> 80-100 is broadcast fm stations
[18:03] <craag> Try 118-120, sounds familiar to me.

[18:04] <Reactive_> whats the best way to scan within that frequency range with sdr#?
[18:04] <craag> Change the numbers to the approx frequency
[18:04] <craag> then you can drag the FFT display side-to-side
[18:05] <mfa298> I think the local tower here is 118.2 but it will be different there.
[18:05] <mfa298> If you're near the coast Marine band can also have traffic (around 156MHz FM)
[18:06] <mclane> upu around?
[18:08] <craag> btw you can use the mouse scroll button while hovering on the numbers to change them

[20:44] <Geoff-G8DHE-M> fldigi or dl-fldigi
[20:44] <eroomde> separate considerations really
[20:44] <eroomde> i.e. choice of programme is not really anything to do with your rig
[20:44] <mfa298> fldigi is good for for general digital modes
[20:46] <Steve_2E0VET> whats the difference between fldigi and dl-fldigi? I suppose i could always google it
[20:46] <mfa298> fldigi is the original version and does tx and rx
[20:47] <mfa298> dl-fldigi adds in the distributed listener parts for HAB use
[20:47] <Steve_2E0VET> didnt realise i have dl-fldigi already installed so will give it a whirl
[20:48] <mfa298> I think if you start up without hab mode it will give you the original fldigi with tx options as well

[20:53] <mfa298> for rtty/psk etc you don't need a tnc just a suitable audio cable
[20:54] <Steve_2E0VET> mfa298, argh uk, from the rigs external speaker ?
[20:54] <mfa298> on the 817 there's a 6 pin mini din (PS/2) connector which has audio in and out which I just feed directly into the soundcard
[20:55] <mfa298> it's the sort of thing a tnc might connect to but you don't need the tnc hardware.

[21:34] <Steve_2E0VET> mfa298, would you know the pinouts you used for your cable
[21:36] fsphil-m (~phil@dab-ell1-h-3-1.dab.02.net) joined #highaltitude.
[21:36] <chrisstubbs> Steve_2E0VET, are you making a cat cable?
[21:37] <mfa298> Steve_2E0VET: you should be able to find them online
[21:37] <Steve_2E0VET> no a data cable (i think)
[21:37] <Steve_2E0VET> i thought CAT was just for controlling the radio
[21:38] <chrisstubbs> I have only ever used mine for tuning, but there are data pins on one of the connectors i think
[21:38] Action: chrisstubbs goes back into hiding
[21:38] kt5tk-m (~kt5tk-m@m954036d0.tmodns.net) joined #highaltitude.
[21:38] <mfa298> if it's the same as the 817 CAT gives you serial control of various features. Data gives you audio in/out
[21:42] <Steve_2E0VET> yes its the same (i think). I have a box which i used for PSK, but not sure if it is working anymore, it connects to the data port, then com1 on the pc and mic and spk on the PC, howeever I cannot get anything out of FLDIGI except a load of "YYYYYYYYYYYYYYYYYYYY" and thats even with the radio turned off
[21:43] <mfa298> I just found a pdf manual and the connector looks similar
[21:43] <mfa298> is a 6pin mini din (same as a PS/2 keyboard/mouse)
[21:43] <Steve_2E0VET> the data and cat are both 8 pins i think
[21:43] <Steve_2E0VET> is it 6?
[21:43] <mfa298> cat looks to be 8, data i think is 6
[21:44] <Steve_2E0VET> yes thats right
[21:44] <mfa298> they're a similar size jack but different pins
[21:44] <mfa298> Page 33 (page 35 as resported by acrobat reader) in the manual by the looks of it
[21:45] <mfa298> looks like there's a PTT in there as well which is probably what goes to the com port on your existing cable.
[21:45] <mfa298> Data Out 1200bps is the one you want for audio out
[21:46] <Steve_2E0VET> yeah that should work just to get the rtty from the rig to the pc i would think
[21:46] <mfa298> it's the method I use. Means you can hear the audio from the speaker (or turn it down with the volume control) without affecting what the pc gets
[21:47] <mfa298> much nicer than using the headphone jack
[21:47] <Steve_2E0VET> is there anything special i need to know about fldigi? to get that to work?
[21:47] <mfa298> I do the same with the TS-2000 (although that's something like a 13 pin din)
[21:48] S_Mark (~S_Mark@host86-139-98-74.range86-139.btcentralplus.com) left irc: Remote host closed the connection
[21:48] <mfa298> using the data connector is exactly the same as using a 3.5mm jack to the headphone jack except that it's not linked to the volume (and possibly the squelch)
[21:52] <Steve_2E0VET> i ssem to be getting a waterfall in fldigi now, but no decoding
[22:05] <fsphil-m> Make sure SQL is off, and fldigi is set to rttyr
[22:06] <Steve_2E0VET> where is SQL?

[22:06] <Steve_2E0VET> argh got it
[22:07] <Steve_2E0VET> i am following the wiki and it says adjust volume and frew till you get 2 straight lines but i cannot seem to get those lines
[22:12] <crash_18974> hi guys. I've been watching the kt5tk-4 balloon since this morning. How long is something like that expected to fly?
[22:13] <fsphil-m> You'll only see two lines if you're tuned onto an rtty signal
[22:14] <Steve_2E0VET> the wiki seems to suggest i will see 2 lines
[22:14] <SpeedEvil> crash_18974: It can be a day or two - depending on exact details
[22:15] <SpeedEvil> crash_18974: If that trend line of alttiude continues overnight - it won't quite reach ground - and will then ascend back to 6000m or so when it gets light.
[22:15] <SpeedEvil> crash_18974: Assuming it doesn't rain, or the balloon has not sprung a leak
[22:15] <SpeedEvil> And assuming the battery keeps going
[22:15] <crash_18974> SpeedEvil: thank you. It's an intriguing hobby you guys have. I just stumbled in because some of you also use the same radio chips that the RC guys use.
