[09:26] <AndyEsser> it's a closed format/system
[09:27] <swaledale> yeah, i think it does a job well
[09:27] andycamb (~andycamb@85.255.234.177) joined #highaltitude.
[09:29] <dbrooke> I've not had much success with 868 previously, but this antenna should be much better at low elevation.
[09:29] <AndyEsser> o absolutely, if you just want to get data from A to B..Z and not too fussed about the underlying hardware or anything, then it's great
[09:29] <AndyEsser> but... I like to tinker and write/build my own stuff :)
[09:29] <swaledale> yes its less of that I guess
[09:31] <dbrooke> Agreed on the closed format being less attractive. It does however allow for trying some new things relatively easily, as Dave has done with repeating and uplinks and so on.
[09:32] <AndyEsser> Absolutely
[09:32] <AndyEsser> which is why I'll get some lora stuff so I can receive and what not
[09:32] <AndyEsser> I just doubt I'll ever fly a lora tracker
[09:32] <AndyEsser> if/when I ever get around to flying something

[09:33] <swaledale> i think sometimes the decision to fly a certain tracker depends on what the listeners are willing to use. at the moment there seems to be a good balance, so plenty of choice
[09:33] <AndyEsser> yea
[09:33] <AndyEsser> I don't imagine RTTY listeners are going to disappear any time soon though

[09:33] <AndyEsser> it's ridiculously simple for anyone to make a tracker for RTTY and for anyone to receive
[09:33] <AndyEsser> so it's very low barrier to entry
[09:34] <swaledale> no wont disappear i dont think, lora has been better for getting images down, 868lora is interesting for fast image download
[09:34] <dbrooke> AndyEsser: you might still get to flying something before me 8-) I built a test tracker a few years ago ...
[09:34] <mfa298> the other thing that I don't like about lora is that it's close to becoming a leave going and forget system so ends up being more like aprs and we loose the community
[09:34] <mfa298> at least with rtty and other modes you generally need to do something per flight and there's a lot more community about it
[09:35] <dbrooke> mfa298: agreed
[09:35] <swaledale> i think you can still do plenty of building with the tracker side, and having automated listening helps those with less time or those schools who want to focus on the soft skills etc
[09:35] <AndyEsser> swaledale: absolute,y if the goal is the flight itself, and not the tech
[09:36] <AndyEsser> that's what a PITS + LORA is great for
[09:36] <swaledale> totally
[09:36] <swaledale> loads of choice, always the best way

[09:37] <swaledale> for beginners theres enough to worry about getting the thing in the air and making sure it lands properly before the tracker stuff!
[09:37] <mfa298> swaledale: there's plenty of people who mostly (or only) just track flights, I did get a lora module but done very little with it as there's not much of interest in it for me, I'll spend a couple of hours setting it up then mostly have to do nothing with it ever
[09:38] <mfa298> I don't see a lot of fun in that

[09:39] <mfa298> at least with an open system I can play with various bits (antenna, radio, radio settings, decoder settings) to get the best out of it
[09:39] <dbrooke> the README was added to protect edmoore from bank switching
[09:41] <fsphil> to get a better interest rate?
[09:42] <M0XIN> Protext? Don't some banks give you £100 if you switch?
[09:43] <fsphil> I wonder if bank switching is why those PICs never got gcc support
[09:46] <dbrooke> hah
[09:46] <dbrooke> he said it needed a warning 8-)
[09:47] <gonzo__> have had that with emulators. Someone decides thet will add bank switchinbg and the eHW emulator system can't support it. (And they wonder why development/bug fixinhg then takes 5x as long)

[10:07] <samir_> Hello everyone - newbie here - is the blue circle over the payloads on the tracker the radio horizon?
[10:07] <gonzo__> blue is the 0deg horzon
[10:07] <gonzo__> green is 5deg (/)
[10:07] <gonzo__> (?)
[10:09] <samir_> Thanks - so people within the blue should be able to receive?
[10:09] <AndyEsser> in theory yes, as long as there aren't buildings/hills/etc in the way
[10:10] <AndyEsser> depending on your eleveation and equipment, you may need to be somewhere between green and blue before you see the signal
[10:10] <mfa298> depends on their surroundings and equipment. Most people should start hearing somewhere between the blue and green circles
[10:10] <gonzo__> I am in a valley, so I loose signals somewhere between the green and blue
[10:10] <mfa298> for instance, stuff to the east of me I struggle with as the buidlings in the way (lots of re-inforced concrete and steel isn't good for radio)
[10:11] <gonzo__> close in obstructions are a pain
[10:11] <gonzo__> as is local noise in a built up area
[10:11] <AndyEsser> mfa298: I have a blind spot up to about 8000m south-east ish.. which is unhelpful with the majority of launches
[10:11] <AndyEsser> due to my roof
[10:12] <gonzo__> you don't bet toooooo m uch general noise up at 434, but there are lots of chirps from other 434 devices

[13:45] <pjm> is the SSDV stuff running on 869.850 ?
[13:46] <dbrooke> yes
[13:49] <daveake> was expecting 36km ... predictor said 38.5 and Pawans are known underperformers
[13:50] <AndyEsser> give it a little blue pill next time
[13:50] <swaledale> lol
[13:53] <bertrik> the X0 signal appears to be very stable here

[14:02] <Geoff-G8DHE> Yes it was contnous
[14:02] <Geoff-G8DHE> on both of them
[14:03] <AndyEsser> no bad lines?
[14:03] <Geoff-G8DHE> no bad lines - there is a gap in the X0 one where it pops of to do LoRa
[14:03] <AndyEsser> ok cool
[14:03] <AndyEsser> cheers
[14:03] <AndyEsser> :)
[14:04] <bertrik> what LoRa settings are you typically using (spreading factor, bandwidth, error correction rate, implicit/explicit header, "DE"-bit)?
[14:06] <Geoff-G8DHE> I think you will find as per the list that daveake put together for the Modes 0/1/2/3 in the gateway.txt config file

[14:10] <bertrik> Geoff-G8DHE: ah yes, thanks
[14:10] <Hes> Mode 0 didn't work for me without manual frequency adjustment, mode 2 worked better.
[14:10] <Hes> (for cat tracking.)
[14:11] <Geoff-G8DHE> I tend to keep AFC off to begin with then turn iton once tracking the signal, otherwise noise will sometimes jump it many 10KHz!
[14:13] <Hes> Yep, I was hoping to do unattended receiving with a remote receiver, and leave it all to the AFC.
[14:14] <Geoff-G8DHE> Lot of trees in PiSky landing area :-(
[14:16] <andycamb> Hopefully the satellite image for the landing area is right and it just missed the trees
[14:16] <bertrik> how I understand LoRa, it's actually quite sensitive to drift and doppler, and a low bandwidth with a high SF makes it worse
[14:16] <bertrik> mode 2 is 6 times better than mode 0 in that regard
[14:17] <Geoff-G8DHE> Once tracking leave AFC on not had a problem once locked on.

[14:20] <bertrik> I can still see the X0 signal clearly, but get no successful decodes anymore, and it's drifting down in frequency for me
[14:21] <Geoff-G8DHE> yes it seems to be spinning and fast flutter on it the uX0 signal on 434.350 is stable however!
[14:23] <bertrik> the 434.5 is stronger for me, what payload is that?

[14:45] <daveake> Well we have a landing position ...
[14:46] <swaledale> how high in the tree is it? :)
[14:48] <daveake> Given the sound of gunfire, I suspect that trees aren't going to be today's issue
[14:48] <daveake> It's a military firing range
[14:48] <AndyEsser> RAF Thetford?
[14:49] <swaledale> Does Steve not sell kevlar vests?
[14:49] <dbrooke> ssdv looks like in a tree
[14:50] <gonzo__> looks like a standard rifle range, to the south of yuou
[14:50] <gonzo__> probably not going to be a problem
[14:50] <swaledale> yes rifle range to the south
[14:52] <swaledale> thats a shame, a few hundred yards more and it'd be on McDonalds roof
[14:52] <dbrooke> on the zoomed in OS map it's just outside the danger area
[14:53] <gonzo__> that may be where the shooting is coming from

[14:53] <gonzo__> looking at it, you will probably have to go and chat with the range officer. May have to wait till they are done for the day to go down the tracks
[14:54] <swaledale> yes its right in that bit of land between Thetford Rifle Range and Thetford Golf Club
[14:54] <dbrooke> crikey! 81m X0 LoRa @ 14.5km

[18:26] <Laurenceb> anyone here ever used serial ports on PC?
[18:27] <Laurenceb> I'm utterly stuck atm :(
[18:27] <Laurenceb> horrible lag
[18:27] JDat (JDat@89.248.91.5) joined #highaltitude.
[18:30] <Laurenceb> atm I've been trying QSerialPort, but I've hit a brick wall as far as reducing lag below ~1second goes
[18:30] <adamgreig> christ what
[18:30] <adamgreig> i use pyserial, it's cross platform, and never noticed any lag at all
[18:30] <adamgreig> and super duper easy?
[18:31] <adamgreig> like Serial.serial("/dev/ttyUSB0", baud=115200) or Serial.serial("COM3") or whatever
[18:31] <adamgreig> in C sort of things I'd probably just stick to the native OS functions for this sort of thing, they're not super hard
[18:31] <adamgreig> in linux you basically just open the serial port file, in windows I don't recall it being much worse
[18:31] <adamgreig> 1 second lag is intense
[18:31] <adamgreig> is this a real serial port or an emulated usb one or what?
[18:32] <daveake> I've indirectly used pyserial on PC/windows no issue
[18:33] <AndyEsser> adamgreig: can confirm, in windows, it's as trivial as file open/read/write just slightly different names
[18:36] <Laurenceb> interesting
[18:37] <Laurenceb> I've used pyserial before without issue
[18:37] <Laurenceb> <adamgreig> I'm seeing it with both usb devices and rfcomm
[18:37] <Laurenceb> I suspect QSerialPort does internal buffering with weird internal timeouts
[18:37] <adamgreig> quite possibly
[18:38] <Laurenceb> as I'm getting occasional chucks of 512 bytes at a time
[18:38] <adamgreig> maybe you can change the buffer size or flush the buffer
[18:38] <Laurenceb> flush() doesnt help me :-/
[18:38] <Laurenceb> I'll investigate using C without the QSerialPort abstraction
[18:38] <AndyEsser> Laurenceb: what OS are you on?
[18:39] <Laurenceb> but then it'd be harder to make it cross platform
[18:39] <Laurenceb> linux, but targeting OS X
[18:39] <AndyEsser> ah ok
[18:39] <AndyEsser> nvm then
[18:40] <Laurenceb> its major annoying as gui functionality relies on bouncing packets off a device to check its supported features
[18:40] <Laurenceb> everything goes glitchy and impossible to follow :(
[18:41] <adamgreig> osx and linux cross platform should be pretty easy for serial ports
[18:41] <adamgreig> basically the same deal
[18:42] <Laurenceb> yeah I'll have to investigate pure c/c++ :(
[18:42] <AndyEsser> :)

[18:43] <Laurenceb> my code is on github
[18:43] <Laurenceb> https://github.com/Laurenceb/Display_gui/blob/master/portselectdialog.cpp
[18:43] <Laurenceb> there is quite a lot of "port discovery" stuff that QSerialPort helps with
[18:43] <AndyEsser> o wait, you're using Qt aren't you...
[18:43] <Laurenceb> yes
[18:43] <AndyEsser> *shudder*
[18:44] <Laurenceb> heh
[18:44] <AndyEsser> the port discovery stuff should be fairly trivial, just a case of look for /dev/tty* devices matching what serial ports would look like
[18:44] <Laurenceb> I was enthusiastic until I _thought_ it was 95% complete

[21:58] <daveake> Yeah pretty easy
[21:58] <daveake> In a tree but easily reached with a pole
[21:59] <daveake> Managed to snag a payload line on the first attempt
[21:59] <daveake> Then just pulled till I could grab it
[21:59] <daveake> Got the parachute back too
[21:59] <daveake> Some fun off-roading to get ther

[22:00] Action: AndyEsser feels better about wanting to get a truck type thing for hab recovery :)
[22:00] <daveake> I had the dashcam running so I have footage of the drive and the escape :)
[22:00] <dbrooke> sounds like fun
[22:00] <daveake> That truck earned its keep today
[22:00] <daveake> No chance of getting there in a regularc ar
[22:01] <dbrooke> I was in some interesting places in Derbyshire in my Landy a few weeks back
[22:02] <dbrooke> is there any way to tell if the uplink was received? most of the time there were enough receivers to not have any missing packets
[22:02] <dbrooke> so I couldn't convince myself it was actually being useful
[22:05] <daveake> For images?
[22:06] <daveake> I /think/ fsphil's SSDV API can return that
[22:06] Action: fsphil beams in
[22:07] <fsphil> the receiver callsigns are listed on the ssdv page already
[22:07] <daveake> Is that an old transporter?
[22:07] <daveake> He means per packet
[22:07] <fsphil> ah
[22:07] <dbrooke> yes, I just wondered in the repeat request had worked
[22:08] <dbrooke> s/in/if/
[22:08] <daveake> oh
[22:08] <daveake> well the telemetry has rx count, snr and rssi for last packet
[22:09] <daveake> message_count=0 however :(
[22:09] <fsphil> strange, the uplink has worked before
[22:09] <dbrooke> right
[22:10] <daveake> couple of things
[22:10] <dbrooke> I wasn't sure if that should have shown received SSDV requests or was for your text messages
[22:11] <daveake> one is, I didn't turn the rtty off during the uplink periods
[22:11] <daveake> as it's 50 baud this time, that would have meant long "off" periods
[22:12] <daveake> second, previously the rtty antenna was above thee 868 one, here it was alongside (tho ~40cm away)
[22:12] <daveake> So I expect the lora 868 saw rather more noise from it
[22:17] <dbrooke> OK, I received a lot more than I have done previously on 868 so am fairly happy that my setup is working reasonably given the coax length
[22:17] <dbrooke> was just curious about the uplink
[22:18] <Ian_> What is your coax, RG178 and how long please?

[22:18] RocketBoy (~steverand@90.211.138.154) left irc: Client Quit
[22:19] <fsphil> the callsigns per packet are indeed available via the api
[22:20] <dbrooke> Ian_: Not quite that bad, mostly RG213 length about 20m and then about 3m of RG58
[22:21] <dbrooke> with various adapters too
[22:21] <Ian_> Thanks, I was thinking of sma connectors and got myself side tracked.
[22:23] <dbrooke> the 213 has N which goes via BNC to RG 58 through the wall to a wall plate and an RG 58 patch lead with BNCs and then an adapter to SMA on the LoRa board
[22:28] <Ian_> Right. Reason for asking is that I normally run 5 to 40W on 70cm to a W300N colinear through around <10m of RG58 to the N on my IC7000. I'm at the point where my swaged poles are up for replacement and of course \
[22:30] <Ian_> am thinking of re-siting them and sort of thinking that a LoRa gateway up a pole close to a couple of antennas for 434/868MHz would be good and for data to flow down the garden, but don't want to fry the LoRa front end.\
[22:31] <Ian_> so will have to think about something to prevent overload when I'm working an evening sked
[22:33] <daveake> So, this is how to escape from an MOD firing range if you get locked in ... https://youtu.be/pTJ6Gjkg86U

[22:36] Action: daveake adds "big hammer" to chase car stock list
[22:37] <Ian_> Ultimate backup - carry a lump hammer, in case man in high-vis is unavailable
[22:37] <Darkside> Ian_: my solution to not frying the lora chip was to put a band-pass cavity filter in front of it :P
[22:38] <Darkside> not the easiest things to get hold of though
[22:39] <Ian_> Good for 868MHz, must investigate coaxial stub filters . . . carefully! More of a problem for the 434MHz side of things of course.
[22:40] <Ian_> but thanks for the heads up. On a rx only installation I could always get a realy to short the input when not actively tracking.
[22:40] <fsphil> also, add high-vis jacket incase official high-vis guy isn't around
[22:41] <fsphil> you can get away with breaking a gate open if you have a high-vis jacket
[22:41] <Ian_> s/realy/relay
[22:42] <dbrooke> I was contemplating putting the Pi with dual band LoRa board nearer the antennas but I also use them for other things so would need some coax relays and probably habamps up there too - gets complicated ...
[22:42] <Ian_> Alternatively carry your own padlock and either put it through the hole or if a chain, lock the chain so that it can't be used to lock the gate. High vis man might smash your lock and lock you up though!
[22:43] <fsphil> I wouldn't trust a Pi up where you can't get at it
[22:44] <dbrooke> not had problems at ground level, but that's not to say it wouldn't misbehave when out of reach
[22:44] <Ian_> Mount the Pi and LoRa board near the foot of the mast in a workshop and feed the data back to the house
[22:44] <Ian_> Then it will only misbehave when it's hissing with rain . . . :)
[22:44] <dbrooke> I might just put the amps up there with relays to bypass them for transmit
[22:45] <Ian_> Spider Pi reset!
[22:49] <fsphil> I've had earwigs crawl into the ethernet socket on the mountain Pi.
[22:49] <fsphil> well, not the Pi itself but the wifi module
[22:49] <fsphil> if there's a way to screw it up, nature will find it :)
[22:50] <dbrooke> With those type of farm gates (I think that one's similar) I've unbolted the top hinge and lifted it off the bottom hinge (when it was illegally obstructing a public right of way of course) and then put it back together after driving through
[22:51] <dbrooke> anyway that lock didn't last long
[22:51] <SpacenearUS> New vehicle on the map: 03VK5QI-9_chase - 12https://tracker.habhub.org/#!qm=All&q=VK5QI-9_chase
[22:56] <daveake> dbrooke: The top hinge had had the threads mangled (possibly with the same hammer) so that wouldn't have been an option even if we'd had a large spanner with us
[22:56] <daveake> We did look into a few options, including getting the 4x4 up a hill and out that way (no chance- fenced in)
[22:59] <dbrooke> ah right, when you drive an ancient Land Rover you normally carry a large spanner or two 8-)
[22:59] <dbrooke> in the above case a non-damaging approach was needed anyway
[23:00] <dbrooke> but if you can call on an official hammer wielder that's not a problem
