[09:16] <fsphil> just in time for getting in my nestbox
[09:16] <fsphil> assuming they don't sell out instantly
[09:17] <craag> a slightly-pricier esp8266
[09:17] <daveake> slightly more integrated, faster and more reliable one too I guess :)
[09:18] <craag> maybe a little ;)
[09:18] <fsphil> esp8266 can't do h264 encoding
[09:18] <craag> and can't run full python #importantthings
[09:18] <craag> or nodejs #moreimportant
[09:18] <daveake> I've ordered one. Might get another at the piparty this weekend

[09:22] <Geoff-G8DHE> Tks ron
[09:25] <richardeoin> how's the signal compared to previous ubseds flights?
[09:25] <richardeoin> it's a new radio
[09:26] <Geoff-G8DHE> So far not heard seen anything .....
[09:26] <Geoff-G8DHE> but its low still under the line of the Downs
[09:28] <mfa298> I might just stick with the CHIP, $9, has decent support, wifi/bt, lipo charging and 4G of storage (8G for those of us that got in early)
[09:28] <mfa298> I can also see some people getting a bit peeved with the zero-w being launched - all those who've been waiting a long time (at least in Pi terms) for the 3A

[09:34] <Geoff-G8DHE> Mumm not a sign of UBSEDS23 here ? it should be above my horizon .... odd
[09:36] <daveake> For me that would mean I forgot to connect the aerial, or something similarly stupid :)
[09:36] <Geoff-G8DHE> I know I've just been checking that, but can see other signals, aerials on power to pre-amp duh whathave I forgotten
[09:37] <daveake> Last time, chasing jakeio's flight, it was the 817 listening to the front socket not rear. It's a classic.
[09:38] <daveake> I wondered why no signal at all, minutes after LoRa kicked in.
[09:39] <Ron_G8FJG> richardeoin ; perhaps not so strong a signal...had to wait for blue line..previous flights decoded before..
[09:40] <Ron_G8FJG> the GMSK signal makes a mess of the waterfall !!

[09:53] <dbrooke> I'm getting partial decodes at 0.35° elevation, previous flights would have been solid above the horizon
[09:54] <dbrooke> ah, green just now
[09:54] <Geoff-G8DHE> yup a partial for me this time as well
[09:55] <dbrooke> that claims to be 0.38° 197.1km

[10:03] <DL7AD1> fsphil: i started a test last night which was going over the night, and as i woke up, the images were already deleted.
[10:04] <gonzo_> nice, first packet is green

[10:37] <craag> richardeoin: Up to ~ -100dBm on websdr ax rx, but no packets seen in live log
[10:39] <richardeoin> craag: it did manage a few packets about 15 minutes ago
[10:39] <craag> oh cool :)
[10:40] <richardeoin> but it has been decoding at ~ -110dBm in testing, so something isn't quite right
[10:41] <craag> Might just be interferers :/ we pick up a fair bit of terrestrial noise on the websdr

[10:49] <craag> just clearing last bits of red tape to allow our feet to touch the roof..
[10:49] <gonzo_> nice, what control are you looking at?
[10:49] <craag> control in what way?
[10:49] <gonzo_> pc-rototor
[10:50] <craag> g-5500 with one of my interfaces
[10:50] <gonzo_> for sat work as well as hab?
[10:50] <craag> yeah
[10:51] <craag> I found coding my own controllers was easier than working around the limitations of the existing ones
[10:51] <gonzo_> and a TX backup for a few years time when Tim flies again!
[10:52] <craag> for hamtv I had an stm32f4+ethernet interface doing the whole TLE download -> motor relay control
[10:52] <craag> heh yes
[10:53] <craag> although the station will be primarily VHF RX, UHF TX at that point
[10:53] <gonzo_> for years there were few options of interfaces. I assume that auduino/pi there are a few more now
[10:53] <craag> (for our cubesat)
[10:55] <PE2BZ> !dial ubseds23
[10:55] <SpacenearUS> 03PE2BZ: Latest dials for 03UBSEDS23 10(a5e3): 033.58 MHz, 434.634 MHz, 434.63347 MHz, 434.6339 MHz, 434.63378 MHz
[10:58] <craag> Yeah I tried with the K3NG arduino, and the amsat serial interface
[10:59] <craag> but also it was fun to write my own, and am completely bypassing the g-5500 control box for v2 :)
[10:59] <craag> no more relays \o/
[11:00] <craag> This'll then mean we'll just have an API on the groundstation control pc for doing manual control, or selecting any orbital/sub-orbital payload :)
[11:01] <gonzo_> in the process of doing that too (building a new control box), but I'll stick with relays.
[11:01] <gonzo_> still on the amsat/lvb ones, as I have a few
[11:02] <craag> I've got 0.1 deg position measurement (plus mechanical play in the gearbox), but the variance on when the relay stops after you tell it to switch off is nearly a degree :(
[11:02] <craag> of course for vhf/uhf this isn't really relevant...
[11:03] <craag> but it does open up smoother tracking motion
[11:03] <craag> which'll be easier on joints and such
[11:04] Laurenceb (~laurence@host86-159-86-245.range86-159.btcentralplus.com) left irc: Ping timeout: 240 seconds
[11:06] <gonzo_> i rewrote the lvb code (as I didn't have the clmpiler that howard used) and changed the maths to do 0.1degs. The ADCs are 10bit on that PIC, so should be able to sue a bit more of that now
[11:07] <gonzo_> as yous ay, +_ a few deg on yagis isn't much
[11:07] <gonzo_> I also built one with a VFD, as that just looks nice
[11:08] <gonzo_> did need to tweak the sw a bit for that too
[11:08] <craag> did you use a VFD with the g-5500?
[11:09] <gonzo_> nope, an lvb
[11:09] <craag> I mean the motor unit
[11:09] <gonzo_> nope, this was for a cctv pan/tilt head
[11:09] <craag> ah k
[11:10] <gonzo_> but would work on anything
[11:10] <craag> so I was looking at vfd, my v2 board will be capable of it.. (frequency derived from mcu)
[11:10] <craag> but the g-5500 motor unit uses a capacitor in the head unit to deliver a phase-shifted waveform to the second winding
[11:11] <craag> the second being the one you aren't driving
[11:11] <gonzo_> mine came from Kevin Avery and has the same command set as the hitatchi chips on the lvb
[11:11] <craag> and of course this is frequnecy specific
[11:11] <gonzo_> you generate your own ac?
[11:11] <craag> that's the plan
[11:11] <craag> so I can run it off DC batts
[11:12] <gonzo_> interesting
[11:12] <gonzo_> I go low tech and use relays, txfmmr and a cap
[11:12] <gonzo_> yep, that would be good
[11:13] <craag> 24V -> H-bridge, gives me 17V RMS
[11:13] <gonzo_> I have a tripod with a pan/tilt head on, but needs mains
[11:13] <craag> Less than specced, but I don't need nearly the torque
[11:13] <gonzo_> the tripod one is 120v ac motors anyway
[11:13] <craag> Might just use a 36V supply when on mains
[11:14] <craag> heh
[11:14] <gonzo_> I have some fat step up switchers somewhere]
[11:15] <gonzo_> got loads from nwork and gave them to the beacon group to sell
[11:15] <gonzo_> 10amp?
[11:15] <gonzo_> 12in 24dc out
[11:15] <craag> I'd also like it as electrically quiet as possible ;)

[11:16] <craag> but yeah, maybe an option
[11:16] <gonzo_> they are actually 1:1 isolated blocks, but they stack the output on the Vin to get 24v
[11:16] <craag> am making the control work and then will play with power supplies
[11:17] <craag> Am also thinking, as it'll need ethernet ocasionally to update TLEs (store in flash), could charge over PoE :P
[11:17] <craag> this is more for a portable use for me now, the control block will be the same as the cubesat GS though (if it works)

[12:07] <richardeoin> craag: awesome, we've got a similar ground station in the works for the cubesat project that is starting up at bristol uni
[12:07] <richardeoin> how are you planning to deal with grounding btw?
[12:08] <richardeoin> with the metalwork on the roof being connected to the strutural ground, but the shack being connected to the mains ground
[12:08] <richardeoin> am aware the correct answer is 'consult a qualified electrician' and that will happen too
[12:16] <craag> all metalwork on the roof connected to structural ground. We're mounting the mast on an existing railing with metal fixings so this is easy. Then lightning protectors on all coax just before entry to the building, again to the structural ground.
[12:18] <craag> We're overshadowed by a far taller building to the East (sky-view *= 2/3;) which building estates have told us removes any of their concern for it anyway.
[12:19] <craag> so we're mainly proect
[12:19] <craag> so we're mainly protecting against static buildup
[12:21] <fsphil> do you have to be careful that the rotator psu / radios are all isolated in the shack?
[12:22] <craag> rotator psu is a fun one. And is one of the reasons I'm playing with controllers. Might be nice to put all control electronics on the roof and have just an isolated data interface to the control PC
[12:23] <craag> radios will be DC-decoupled, with DC biases on both coaxes anyway, and the lightening protection to handle high energy surges.
[12:25] <craag> coax relay switches are on a wishlist, to switch receiver and also to manually add isolation in a storm.
[12:25] <craag> (the station will be completely remotely-operated)
[12:26] <fsphil> that's a good idea
[12:26] <fsphil> might borrow that for when I get an x50 installed on the mountain station
[12:27] <daveake> Add on of those lightning detector boards, and you can have it automatically disconnect :)
[12:27] <daveake> one
[12:28] <craag> lol
[12:28] <craag> note that coax relays do have a failure rate (getting stuck), especially when acquired cheaply
[12:28] <richardeoin> ah I think the plan here is to put the lightning protectors on the masthead
[12:28] <richardeoin> before the LNAs
[12:29] <richardeoin> before the polarisation switches even
[12:29] <gonzo_> electrically isolating the earths is going to be difficult. You could float the whole DE/balus assy at the antenna, but I wonder what that will do for your common mode pickup?
[12:29] <craag> sorry not dc-isolating the coax shield

[12:31] <craag> This is subject to me finding out what everything else on that roof is doing for earth
[12:32] <craag> (solar panels, with all the control kit in a rack next to where we're putting the RXs)
[12:32] <craag> richardeoin: We're just wiring up Circ-polarised, no switches on that.
[12:32] <gonzo_> hopefully V/UHF will be ok with PV.
[12:33] <craag> It's experimental kit, so only powered on for a few hours every few weeks I've been told
[12:33] <craag> and all appears to be industrial grade controllers, not consumer rubbish
[12:33] <gonzo_> poss not CE marked then
[12:34] <gonzo_> ah, ok
[12:34] <craag> It's the panels that are the experiment I think...
[12:35] <gonzo_> do you get to use them for the rest of the time then?!
[12:35] <craag> lol that'd be good
[12:36] <dbrooke> they'll probably let you use them at night

[12:38] <fsphil> how do the lightning protectors work? main path breaks down over a certain voltage?
[12:41] <craag> gas cartridge between coax center and outer
[12:41] <craag> breaks down at V++++
[12:41] <craag> won't protect your radio, but might stop it burning the place down
[12:41] <fsphil> mmm
[12:41] <fsphil> maybe not worth it for my setup
[12:42] <craag> Probably not
[12:42] <craag> Tends to be advised when you have an outside -> inside interface
[12:42] <craag> as it keeps the majority of the destructive energy on the outside of the building
[12:43] <fsphil> the electronics isn't grounded up there, so lightning may not see it as a good path
[12:43] <craag> or is designed to...
[12:44] <fsphil> though I need to put in an antenna post, that'll ground it

[17:57] <Amegle> Hello
[17:58] <Ian_> Hello :)
[17:58] <Amegle> Hi, how would you get around the GPS limits
[18:00] <Amegle> Like how it doesn't work if you go over 18 km
[18:01] <Ian_> You mean altitude limits? Easy answer use a Ublox chip based GPS and put into flight mode, rather than pedestrian as your package gets much above 2km or so
[18:02] <Ian_> https://store.uputronics.com/index.php?route=product/category&path=64
[18:02] <SA6BSS-Mike> here is a guide for ublox http://ava.upuaut.net/?p=738
[18:08] <Amegle> Also, when people say that the altitude limits disables GPS units, does that mean they stop all together, so you have to get a new one?
[18:08] <Amegle> Or just they won't report any data over the altitude limit
[18:08] <daveake> Latter
[18:08] Halfdead (~Halfdead@71-84-11-44.dhcp.trlk.ca.charter.com) joined #highaltitude.
[18:09] <Ian_> No, the idea of the limits, altitude and velocity is make it difficult to make cruise missiles at home
[18:09] bugzc (~1@unaffiliated/bugzc) joined #highaltitude.
[18:10] <Ian_> They just stop reporting above a nominal 12km or so. Ublox chips in flight mode are good to 50km - no brainer frankly.
[18:10] <Amegle> Ok, cheers
[18:10] <russss> the limits trigger if you go above 18km at above 1000kts
[18:10] <Ian_> So you will have to make do with a HAB instead . . . :)
[18:11] <russss> some GPS devices didn't used to interpret those limits correctly, but the recommended ones do
[18:11] <Ian_> There are a lot of rocketeers here though!
[18:11] <russss> not many who have put a guided vehicle above 18km I'd wager.
[18:11] <daveake> Some of whom are quite capable of building and coding their own GPS receivers anyway!
[18:13] <nick_> DPRK are more likely to be able to launch a balloon with a special payload than a missile anyway.
[18:14] <russss> those GPS COCOM limits are showing their age a bit anyway
[18:15] LeoBodnar (~LeoBodnar@79-76-231-82.dynamic.dsl.as9105.com) joined #highaltitude.
[18:15] <russss> I suspect the DPRK have already built their own GPS receiver from scratch
[18:17] <nick_> Or from Xilinx?
[18:19] Action: nick_ wonders when the last balloon dropped bombs were.
[18:19] <murb> so GPS is fine for your normal cruise missle?
[18:19] <nick_> Did anyone use them after WW2?
[18:20] <murb> nick_: the japenese used the jetstream for that.
[18:20] <murb> + clever system of weights and balances to keep them at teh right altitude.
[18:20] <murb> managed to blow up some curious people who discovered them iirc?
[18:20] <russss> murb: not sure how well it would perform, but probably.
[18:21] <Amegle> I'm trying to make a guided HAB
[18:21] <murb> the last cruise missle i saw would have had a human pilot.

[18:22] <nick_> Amegle: isn't this what project loon does now?
[18:23] <mfa298> Amegle: depening on where you are there might be a lot more regulation to deal with if the balloon is guided
[18:24] <Amegle> It will basically be a drone strapped to a baloon
[18:25] <Amegle> So i can land it in a specific spot/fly it to me after it lands
[18:25] <nick_> Sounds neat.
[18:25] <nick_> Probably illegal in the UK though :(
[18:25] <Amegle> Well its always worth a try
[18:26] <nick_> The issue being that you should control the drone from line of sight.
[18:26] <nick_> Which I guess is possible.
[18:27] <Amegle> I'll check, its only really so i don't have to spend hours finding it on a farm i don't own
[18:27] <nick_> If you see where it's coming down.
[18:27] <Amegle> I could always go to the spot were it looks like it will land then take control when i see it

[18:28] <nick_> Have we got updated UAV regs now?
[18:28] <Amegle> Err they were thinking about it
[18:28] <nick_> I've not checked for at least a few years, but it was something supposedly in the works.
[18:29] <Amegle> But the government never seems to get anything done at the moment
[18:29] <nick_> There's no opposition, what's to stop them getting everything done?
[18:30] <Amegle> They're distracted by something (Brexit *cough* *cough)
