[04:47] <nigelvh> Photography is one of those things that I think it would be awesome to take pictures that fantastic, but am totally unwilling to put in the time/money/effort into becoming that good.
[04:48] <eroomde> indeed, though i'm finding it more intriguing
[04:49] <eroomde> i don't think it really takes money
[04:49] <eroomde> i'm sure you could get identical equipment to what henri cartier-bresson used for $100 nowadays
[04:51] <nigelvh> I'm sure, but that still doesn't speak to the skill/experience required.
[04:51] <nigelvh> (Or luck...)
[04:51] <eroomde> no ideed, but it's always a nice problem to have when the limit is you and not the equipment
[04:51] <eroomde> plenty of room for progress :)
[04:52] <SpeedEvil> plus, Photoshop
[04:52] <eroomde> and that
[04:53] <nigelvh> Yes, though, it's not like I don't have enough things to learn/practice.

[04:58] <KT5TK> Hi nigelvh
[04:59] <KT5TK> Would you mind to look at your ADF7012 chips and check the date code when they were produced?
[05:08] <nigelvh> Sure
[05:08] <nigelvh> I have two in front of me. One says #1213 and one says #1241.
[05:08] <KT5TK> I have observed quite a variance in rf output and I try to find out what it is
[05:09] <nigelvh> How much difference in output are you seeing?
[05:10] <KT5TK> My best working one is also 1241
[05:10] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) joined #highaltitude.
[05:10] <nigelvh> Hold on one moment.
[05:10] <KT5TK> 1211 is not that good and the ones from 2011 are really bad
[05:12] <nigelvh> My best is a 1213
[05:12] <nigelvh> Though my measurements have always been with a PA, so the PA will have some impact on that.
[05:13] <nigelvh> But I seem to get something like 250mW out of a 1213 and like 160mW out of a 1241 (With PA)
[05:13] <nigelvh> Could easily be the PA
[05:14] <KT5TK> Hmm, never had a 1213, only 1215
[05:15] <KT5TK> OK, thanks. Good to know.
[05:15] <nigelvh> How big of differences are you noticing between yours?
[05:15] <KT5TK> Unfortunately I have a rail of 10 1211s
[05:16] <KT5TK> difference of about 5 dB
[05:16] <nigelvh> That's really significant and could easily explain the difference I see in mine.
[05:18] <nigelvh> I was wondering why I was seeing such a difference in mine.
[05:19] <KT5TK> I'm preparing a radio for DL and I'm thinking to put a little booster amp between the ADF7012 and the RF6886
[05:20] <KT5TK> Something like this: http://www.mouser.com/Search/ProductDetail.aspx?R=AG303-86Gvirtualkey66910000virtualkey772-AG303-86G
[05:21] <arko> eroomde: around?
[05:21] <nigelvh> That would definitely mean you wouldn't need to drive the 7012 to full.
[05:21] <KT5TK> which I can build on the breadboard portion of the PecanTurbo
[05:22] <KT5TK> I don't get the full 14mW anyways
[05:22] <nigelvh> How much input do you need into the 6886?
[05:22] <KT5TK> rather 1 mW if my measurements are correct
[05:22] <KT5TK> 10 mW in would be good
[05:23] <nigelvh> That should be well within the 7012 range, even if it's poor. Why do you need the boost?
[05:24] <KT5TK> As I said the ADF chips I have have a significant lower output
[05:24] <eroomde> arko: yes
[05:25] <nigelvh> Well, at best the ADF will do 20mW, you not sure you can even get 1mW?
[05:25] <arko> one sec
[05:25] <arko> checking to make sure this is right
[05:26] <KT5TK> I have no good absolute measurment capability but I can hardly drive the RF5885
[05:26] <KT5TK> 5885
[05:26] <KT5TK> *RF6886
[05:27] <arko> oh man
[05:27] <arko> that was a close call
[05:27] <arko> https://twitter.com/cconkle/status/300834740548825088/photo/1
[05:28] <arko> i saw this and thought it was the Wurstkuche in downtown LA
[05:28] <nigelvh> Well, at 31dB of gain, you'd only need 3db to reach the 1db compression point.
[05:28] <arko> thats the place I was gonna suggest for dinner or lunch
[05:28] <eroomde> lol!
[05:28] <arko> turns out it's a new location they just opened in Venice Beach
[05:28] <arko> i was like "WTF!? What kinda timing is this!?"
[05:29] <KT5TK> arko: was that your car?
[05:29] <eroomde> maybe they thought it was a truck
[05:29] <arko> now im like "cool bro, stay away from trucks now ya hear?"
[05:29] <arko> KT5TK nah
[05:29] <arko> some dude
[05:29] <arko> the downtown LA one is alive and well
[05:32] <KT5TK> nigelvh: remember I can always lower the power of the ADF in software and I'd like to have some dB reserve for clean filtering
[05:33] <KT5TK> right now I'm absolutely at the lower end of the gain curve
[05:34] <nigelvh> Makes sense.
[05:35] <KT5TK> The RF6886 draws not significantly more current than the bias itself
[05:36] <arko> ermergerd, kerbal space program has RTG's
[05:36] <arko> time to do deep space missions
[05:36] <nigelvh> I assume since you're focusing on the 7012 that means you haven't had luck with the 4464?
[05:38] <KT5TK> Yeah, not much progress with the 4464 and I need to have a tracker ready until Thursday
[05:39] <KT5TK> Will have to delay that project until I come back
[05:39] <nigelvh> I need to finish up my new design so I can fiddle with the 4464 and see if we can't get something to work.

[05:41] <KT5TK> As I said, I can send you a PCB so that you can try to code the chip before you invest in your own design
[05:42] <nigelvh> If you want to I'll happily play with it, but I'd need to order the parts anyway, so I might as well get my board finished up.
[05:44] <KT5TK> you can have a 4464 and a 27 MHz vcxo from me as well. What takes time is waiting for the pcb
[05:45] <nigelvh> Like I said, if you want to, I'll be happy to play with it and see if I can get something to work.
[05:46] <KT5TK> I'd be happy with any progress on this project.
[05:46] <KT5TK> You just need the small parts
[05:46] <nigelvh> What is on that list?
[05:48] <KT5TK> Didn't make a proper BOM yet. Give me a few minutes
[05:49] <nigelvh> If I can just get enough parts to support the chip, I can wire in SPI to an offboard processor.
[05:50] <nigelvh> I've probably got any resistors I'd need.
[05:50] <nigelvh> Depends on the capacitors, I might have those around.

[05:58] <KT5TK> just a regulator, a ATmega328 with 8MHz crystal and some passives
[05:59] <nigelvh> Yeah. if I really don't care about the output, then it's just a few decoupling caps.
[05:59] <nigelvh> I've got those.
[05:59] <KT5TK> yeah

[11:31] <daveake> I need to update the UKHAS SI unit table
[11:31] <daveake> "Shitload: Amount of gas added above normal to ensure safe liftoff in a blizzard"
[11:32] <mattbrejza> i hope you flew a camera
[11:32] <daveake> 3 gopros
[11:32] <mattbrejza> nice
[11:33] <mattbrejza> despite using that much gas the balloon that was supposed to go up at a nice and slow 3m/s to clear the channel went up faster than you
[11:33] <daveake> All worked throughout the flight, though one stopped on landing
[11:33] <daveake> hah
[11:33] <daveake> What was the ascent rate? I saw 8 at the start and 5.6 later
[11:34] <mattbrejza> yea somewhere around 6
[11:34] <daveake> Cool
[11:34] <daveake> It was impossible to accurately measure neck lift
[11:34] <daveake> In the end I had someone hold the balloon while I stood back to look at it
[11:34] <daveake> Looked plenty full enough :)
[11:34] <daveake> And anyone see the landing speed?
[11:34] <mattbrejza> you had enough land to try and hit though
[11:35] <daveake> Sure, I was intent on missing the trees etc at the launch site

[14:32] <Babs> (Notwithstanding the CAA mandating that a launch can't be within 10 miles of an airfield) - has anyone ever launched from an airfield? Clearly Heathrow is a no go (!), but some of the others can only receive a few light aircraft a day, are as flat as a pancake with no trees and draft free hangars to prepare in and as such are ideal for a launch
[14:32] <RocketBoy> yes I have
[14:33] <RocketBoy> just got the CAA permit for the airfeld
[14:33] <Babs> Hi Rocketboy, just a standard CAA form as per normal non-airfield launches?
[14:34] <RocketBoy> not heard any rule about 10miles from airfild - who told you that one
[14:34] <RocketBoy> airports yep
[14:34] <RocketBoy> thay wuld be a problem]
[14:35] <RocketBoy> yep - just OK with the owners/operators of the airfiled - then tell the CAA
[14:36] <Babs> I'm sure I read it somewherebefore my first launch last year. My mate lives right next to RAF Benson (which may present further complications although it is open to small civilian aircraft) which would make launching a whole lot easier. I'll give them a ring. Thanks.
[14:36] <RocketBoy> yep - then they can co-ordinate the launch like any other takeoff

[15:11] <fsphil> tis
[15:11] <fsphil> the odds of hitting it have got to be tiny
[15:14] <HixWork> how long did it take you to get that prediction right
[15:15] <HixWork> and can you get a NOTAM for it?
[15:15] <Babs> Could you use a reverse geofence to make it burst when it floats over the Isle of Man, then use an altitude controlled drogue to deploy a main chute when its near the ground? If it doesn't float over the Isle of Man, it just carries on over the Irish Sea
[15:15] <fsphil> got it from my hourly, so one go :)
[15:15] <fsphil> and no I can't launch friday :(
[15:15] <HixWork> bugger
[15:16] <fsphil> you'd likely need a controlled descent

[19:25] <fsphil> are you have a problem with it?
[19:25] <PaulCDR> i have wired it up following this design http://ava.upuaut.net/?p=101
[19:26] <PaulCDR> but instead of getting 2 separate freqs, i seam to get the same freq but wider bandwidth
[19:26] <PaulCDR> i think
[19:26] <Upu> http://ukhas.org.uk/guides:linkingarduinotontx2
[19:26] <fsphil> there's a better schematic on the wiki.. http://ukhas.org.uk/guides:linkingarduinotontx2
[19:26] <arko> oh yeah Upu's stuff
[19:26] <Upu> Yeah that article is out of date
[19:26] <PaulCDR> i get a skinny red waterfall then a fat one
[19:26] <Upu> Try the guide on UKHAS its easier
[19:27] <Upu> sorry we changed the original article as it was overly complex and you didn't need 2 pins to drive it

[19:47] <costyn> you being in the USA have the luxury of many many suppliers which will send you stuff without shafting you for ridiculous prices like they do when we order stuff from the USA

[19:50] <arko> supporting yall
[19:50] <nigelvh> I'm sure if it went transatlantic then you could ask the guys here to listen on 144.39
[19:50] <costyn> arko: cool
[19:50] <costyn> nigelvh: absolutely, but arko wants to fit in :P
[19:50] <Upu> well the geofence test worked this weekend
[19:51] <nigelvh> arko's just a conformer
[19:51] <Upu> that was to facilitate the correct ITU prefix for APRS
[19:51] <nigelvh> :P
[19:51] <costyn> Upu: cool
[19:51] <Upu> and to know when we are out of barmy UK radio laws

[19:53] <mfa298> Upu: although technically you probably still can't operate airborne as I think for CEPT usage you're still tied to the uk license terms as well as those for where your visiting.
[19:54] <Upu> good point
[19:54] <costyn> mfa298: spoilsport
[19:54] <Upu> and one I'll just ignore
[19:54] Action: costyn cheers
[19:54] <Upu> no I'm going to look into it
[19:54] <nigelvh> So would that mean that if you were in the us where it's allowed, but using your UK license, you still couldn't?
[19:54] <mfa298> as Upu said, barmy uk radio regs
[19:55] <Upu> As long as we are prefixing correctly and adhereing to the local regulations I think we should be ok
[19:55] <Upu> if all else fails I'll just use someone elses call sign
[19:55] <Upu> only joking
[19:55] <costyn> heh
[19:55] <Upu> costyn pm me your call sign
[19:56] <Upu> actually mfa298
[19:56] <Upu> I think we are ok
[19:56] <Upu> just reading it
[19:57] <mfa298> I was just looking as well, nothing obvious in the section about cept
[19:57] <Upu> https://services.ofcom.org.uk/amateur-terms.pdf
[19:57] <Upu> Section 16
[19:57] <costyn> Upu: I don't have a license unfortunately
[19:57] <mfa298> unless it's hidden in the pesky notes
[19:57] <W0OTM> NASA music is dumb!
[19:57] <Upu> Full license - check
[19:57] <Upu> Temporary visitor - check
[19:57] <mfa298> I might be rembering from the old BR68
[19:58] <Upu> nah looks like we are legit
[19:58] <Upu> as long as we prefix the call sign which is what I intend to do

[22:43] <domlin> what voltage to thyratrons switch at?
[22:43] <chrisstubbs> a little more than 5v i expect
[22:44] <domlin> potatoKV
[22:46] <chrisstubbs> in that range :P
[22:46] <chrisstubbs> im off, night all!
[22:46] <nigelvh> Night
[22:46] <domlin> night mate
[22:47] <domlin> i'm also off guys! wonder if my irc bnc will ever come back online... :S

[22:47] <nigelvh> night is one of those words I always have to think twice about typing.
[22:48] <nigelvh> same length and same first three letters as my name.
[22:48] <nigelvh> I often end up typing "good nigel"
[22:48] <nigelvh> Which is rather patronizing to myself.

[22:50] <arko> hahaa
[22:50] <nigelvh> That's why most of the time I say "evening" because that's not the same as my name

[22:53] <nigelvh> Nice
[22:53] <nigelvh> One of the profs at UW is talking about a cubesat. I would LOVE to help with that.
[22:54] <nigelvh> "Yeah, I worked on that satellite"
[22:54] <nigelvh> "I've built stuff that's in space"
[22:54] <arko> :) its a good feel
[22:54] <arko> i just wish i was closer to the engineering
[22:55] <nigelvh> Yeah, if we did something like a cubesat I would guess I'd be pretty involved in the electronics.
[22:55] <arko> its very expensive to launch
[22:55] <OZ1SKY_Brian> gn
[22:55] <arko> you need to find a ride essentially

[22:56] <arko> govt or edu discount
[22:56] <nigelvh> That's why the university would do it and not me.
[22:56] <arko> yeah hah
[22:56] <arko> UW
[22:56] <arko> i see, derp
[22:56] <nigelvh> Yep
[22:56] <arko> hey, what gpa do you think i need for grad school at UW?
[22:56] <arko> or to transfer as an undergrad?
[22:56] <nigelvh> I've got no idea honestly. I never did any grad school.
[22:57] <nigelvh> I think it also depends on what dept you wanna be in.
[22:57] <arko> EE
[22:57] <arko> i was thinking about UW or Cambridge for grad school
[22:57] <arko> i want to leave CA for a while
[22:57] <nigelvh> I would guess their reqs would be higher than where I hang out in Earth and Space Sciences
[22:57] <arko> hmm
[22:58] <arko> i'll need to look this up
[22:58] <nigelvh> ESS is where all the COOL stuff happens. Plasma thrusters? Yes.
[22:58] <nigelvh> I haven't worked with them at all on that though. I just use one of the labs with one of their big vacuum chambers
[23:01] <nigelvh> ESS does the balloons and rockets classes, so I volunteer with them.
[23:01] <nigelvh> I've gotten to know the profs pretty well over the years.

[23:51] <craag> What actually happened in the horizon launch? Did the radio tracking fail?

[23:52] <MrCraig> Hi all
[23:53] <arko> hello
[23:53] <nigelvh> Howdy
[23:53] <MrCraig> Back in sunny Dallas :-
[23:53] <MrCraig> :-)
[23:54] <MrCraig> I was just looking over the flight data I have for Saturdays flight and the problem is quite clear. We had a predicted ascent of 3m/s but averaged close to 5m/s on ascent. I guess we weighed it wrong or something
[23:55] <MrCraig> That and all the difficult tracking issues (The payload was far from well behaved :)
[23:55] <MrCraig> Just wanted to thank everyone that helped with tracking, it was an exciting flight - a lot of fun for us.
