Is there a dipole with suckers for the Mode S/ADS-B transmissions? So I can bury the PAw but have the aerials out, I was just about to buy the P3I dipole, + GPS mouse, but need the other one.
And, 2nd Q :P, I'm having trouble getting traffic on my SD display, if I connect to Pilotaware it says 'GPS data not received (or similar) so I revert to mini tablet GPS. It clearly has GPS tho' as it can report range and direction to ADS-B targets. In some ways it's better, I don't have the distraction of targets on SD, but I do get the audio via audio cable into the Garmin 345 :P
Thankyou in anticipation, still lovin' it, I'm slowly getting the others in my group to engage.

1. I made my own 1090 antenna dipole using the core an sheath from the cable of an old mag mount version. Very Blue Peter, and works brilliantly. Think I posted a 'how to' somewhere? These antenna are not critical.
2. Getting a report of other traffic is not dependent on your GPS. You need to sort out why yours is not working. Can you leave it running outside with a clear view of the sky for 15 minutes, then post screenshots from the home page and logging page.

Hi Neil
We are having some centre feed horn antennas made as a pair. One for 869.5mhx and one for 1090mhz. These will be available for our range of installation kits for various types of aircraft available soon. This one in particular is for where folks don’t want to or can’t drill holes in their aircraft. The kits should be available in about 4 weeks.
If you can’t wait that long we have found that the existing horn antenn will work ok for 1090 MHz as well as 869. One for each. If you have a Classic you will also need an mcx to sma converter for the Adsb
Pilotaware is always better permanently or semi permanently installed. Better reception and no wires showing

Neil,
Re the ‘fault’ part of your post:-
As per my comment on your other thread, what PilotAware software version are you running? Also is this still a Classic?
What version of SkyDemon are you running?
I take it you have checked that your device is correctly connected to the PAW WiFi, but it isn’t receiving data - is this correct? What message is coming up on screen (please report this as accurately as possible or preferably post a screengrab).
Oh, and if ‘burying’ the PAW, it’s a good idea to fit a USB extension to a ‘spare’ USB port to facilitate updates. It can be a pain trying to do so otherwise.
Thanks.
Regards
Peter

PAw version = 20180520, yes a classic with an SMA pigtail and small antenna for the DVB-T
Skydemon 3.9.5.18618, Galaxy Tab S2 8" SM-T710, Android 6.0.1
yes Wifi connected correctly, yes when trying to Go Flying using Pilotaware it says: not receiving GPS data
Will do a screen grab
leave it running outside with a clear view of the sky for 15 minutes, then post screenshots from the home page and logging page.
Will do

Thanks Neil,
I have a couple of potential issues in mind, but will wait ‘til I see the screengrabs.

Hi Neil
Have you always had this issue or is this something new ?
What is your power supply ?
Couple of experiments to try
1. Try connecting using FLARM rather than PilotAware, to see if this works
2. Get the tablet to 'forget' PilotAware hotspot, reconnect, then try 'go flying' with Pilotaware
3. Connect safari to the PilotAware Hotspot home page, than try 'go flying'
Thx

Hi Lee
It's new, in the last week 6 flights. Will do as you suggest (and the other stuff). Man I have to go the field and possibly flying again 8-D
'Yes dear, got to, Lee said...'

You have to work on the timing of the statement vs being out of the door.
2 seconds is the gold standard. But if you spot a phone call to mother or hairdresser, you have time to pack a toothbrush
-
You have a filter for women on this forum right? I didn't just say that out loud? :-\
Someone in our group (works at Swanwick and switched on) just flew, no problem, so points to wifi issue with my tablet. I will still do full diagnostic etc.
-
I almost bought a GPS mouse, but it sounds like I should just get a USB tail for the GPS blox a dipole aerial for the Pi and a homemade dipole for 1090. Then store the Pilotaware in the cubby hole, fix the aerials to the perspex and GPS to the coaming.
Is there a GPS receiver with Bluetooth which can serve several devices in the cockpit? There's definitely a market
Did you know that Bluetooth is named after a Norse King?

The name was chosen due to Swedish telecommunication company Ericsson’s Viking heritage. The founders felt that Harald Bluetooth’s ability to unite people in peaceful negotiations would be appropriate for a telecommunications technology.
And yes, I work for Ericsson, so I know the story. ;D

Went today to try out your options:
It worked perfectly. I think it was the wifi connect as it would sometimes have trouble connecting. so I cancelled the WiFi connection and re-connected it.
-
I tried to grab/print what I could, I have a few .trk's as well, including ProjectPropeller, but I guess as it's all working now that's not of much interest. Thanks for the help and patience

Update: Flew today for real and 'No GPS' when trying to 'Go Flying' via SkyDemon, aaargh!
So I cancelled the Wifi Connection (I notice it had connected to Pilotaware and report 'problems connecting', but then connects ok)
Cancelled (forgot) the connection, reconnected to WiFi, went back to SD, success! All worked perfectly the whole flight.
It also connected and worked perfectly on the way back. I think it helps if power to the PAw is only connected when the aircraft electrics are established (after engine start)
I hope this helps someone.
I got a brief false mode C red ring once in the 2 flights, I think it was me. The clue is it pops up as red mode C, there's no green - yellow - red. Straight red, then disappears. Other than that, the warnings were very useful, in the circuit it's a great reminder to identify everyone you've heard, and keep looking for the silent / non-emitting.
-
Hi Neil,
Bearing in mind that Mode C responses don't include the aircraft Hex, the 'initial' mode C contact from your own Mode C or Mode S transponder when PAW initially 'finds' it will create an alert, as PAW hasn't yet fully established that it is 'yours' at this point. With the most recent software (20180520) which you are running, this should only happen at first contact.
I notice from your 'Home Screen' that you are running quite an old Raspbian 'Kernel' (3.18.7-v7+). This is a downside of continually updating by 'PilotAware.pgp', which only updates the 'PilotAware' software, not the Linux Core. In view of your continuing connection difficulties, I would recommend a Full Re-install of the latest Software version onto a freshly reformatted microSD card as this will update the Core to the latest Kernel. You need to carefully follow the Full Manual Update Instructions here... http://www.pilotaware.com/wp-content/uploads/2016/09/160901-Manual-Software-Upgrade-1.pdf
As this involves a complete reinstall of the software, you will need to re-enter all your present settings, including your Licence Key and Aircraft Details, so it's best to take a copy or a Screenshot of the 'Configure Screen' before you start. Also download any Track Files first if you want to keep them.
Let me know if this sorts the problem.
Best Regards
Peter

Hi Neil
I think I can see what is happening here.
Can I ask what is the exact shutdown procedure and in what order ?
1. ipad into standby mode,
2. Pilotaware off,
or in reverse ?
PilotAware will only send UDP data to known connected clients, this is the PilotAware or GDL90 type interface
Upon reboot, PilotAware believes it has no connected clients, but I think the iPad is 'thinking' it still has a DHCP IP address allocated.
PilotAware will not recognise the iPAd is connected until
- it gets a DHCP request
This can be due to a timeout, or a 'forget network', or whatever means ios decides
- it sees IP traffic
For instance a connection to the webserver at http://192.168.1.1
I think I can work around this issue, but reproducing your scenario leading upto it is difficult.
If you can describe in excruciating detail the order and method and shutdown, and then startup, I can possibly re-create and test my proposed solution
for the time being the following should work
1. use FLARM connection (this uses TCP not UDP)
2. use 'forget network'
3. Also I think simply accessing the web page http://192.168.1.1 will also force a refresh, if you get the chance to test this, I would be interested in your findings
Thx

Hi Neil
Peter explained what is probably happening here, but I thought I would chip-in
Mode-C is a complete nightmare to handle effectively I have to tell you.
There is nothing to indicate whethe the Mode-C is you or someone else
Bear in mind even if you have an ADS-B tranponder or Mode-S transponder, it will still reply to mode-C interrogation
So we have to 'learn' that this Mode-C is probably you, we developed some pretty complicated machine learning algorithms to do this, but where they cannot work effectively - is the initial interrogation, or an interrogation after a long pause of silence.
So where this will likely produce a false-positive, during take off where you get your first Mode-C ground interrogation ?
When flying in/out of areas covered by ground interrogation ?
Where it gets really confusing, is if you are flying in an area not covered by ground interrogation, but you are interrogated by a TCAS - again the system may initially provide a false-positive
it is the nature of the beast, and this was the very reason you can disable Mode-C detection, but keep Mode-S
Thx

Thanks for the 3 replies. I will do as you suggest and action those / report back when I get chance. Shutdown sequence tends to be PAw off before Samsung tablet.
Now I can reconnect via wifi disconnect/reconnect I'm not concerned by the UDP/TCP. Also now I understand the red Mode C proximity warning I'm OK with that, I show it to others so that they don't overreact. It's quite different to the green then yellow ring warnings, and a bit like getting used to the audio in the circuit, you have to use it to get the most out of it. I advise those that get distracted by multiple warnings in the circuit to mute that channel on the audio panel, but not switch it off, as I'm still listening.

One thing in my aeroplane, the PAW Classic doesn't seem to like engine starts. It'll connect on Wifi but the SDR dongle won't seem to receive anything. Rebooting the PAW brings everything back. I try and remember not to power it up until after engine start, but sometimes I power it up before if it hasn't had a GPS lock for a while to get the GPS location recognised again.
-
Hi Paul,
I have a similar problem. I suspect my battery may be on the way out as I often lose the radio as well during starting and have to turn it back on and wait for PAW to reboot before heading for the Runway, so now trying to remember to start the engine first. :-\
Regards
Peter
-
The voltage *will* drop when the starter motor is engaged. Standard procedure is avionics off before engine start.
-
We have a switch for the cigarette lighter/'auxiliary power source' - I also get the odd problem when I - forget to switch it on after engine start :-\

Interim Report
Sorry guys, I've forgotten what I'm supposed to report on. I've run the PAw across Europe (Vienna - Blackbushe). It worked great. It did stop working after 2 hours on the coaming, but that was clearly thermal stress.
I have external aerials now, and a GPS extension cable. So that is not a problem for the future.
I have plenty of journey logs if you want them.
I'm planning my Rosetta upgrade, and I think I know why you called it Rosetta, discussion for another time...
-
Next version will be 'Babel Fish' :)

Oh come on! I NEED that one, can I beta test? alpha test? borrow one? You can call me Broomfondle

'you are running quite an old Raspbian 'Kernel' (3.18.7-v7+)'
exfirepro:- reloaded from scratch now on kernel=4.9.35-v7+
I will be using the 2 aerials and the GPS extender to keep the PilotAware out of the sun
I'm trying to teach the rest of the group how to use PAw, some are good, some .. meh
I will be sending you the Bridge this week, with a bundle of used fivers. And sourcing a Pi 3+(?) (whichever is current for you) and getting 2 low voltage SDRs. 1 might be included in the Rosetta upgrade, I'll check.
I will upgrade the other 2 PAw (that I passed on at cost) when/if they want to. But they really need to take the lead on that. If I kill em' they won't learn nothin'.
Thanks for the help, let me know if you want any more diagnostics/feedback.

All good on the Kernel update, it ensures that the new PAW software is running on the most up to date ‘base’, which should eliminate the likelihood of issues due to PAW asking the Pi to do something the older Kernel wasn’t designed to handle.
If you’re ordering a replacement RPi, go for an RPi3B NOT the RPi3B+ as that uses slightly different architecture which isn’t supported yet.
Yes, the Rosetta upgrade kit includes 1x low-power SDR. If ordering a second one be careful where you order from as not all ‘Stratux type’ SDRs advertised are the Version 2 type.
I think the intention is to make a ‘Weather Update Kit’ - which will include a second SDR - available at some point in the near future, but as I understand it Keith & Co. are still sourcing appropriate antennas and splitter cables, so not sure yet when this will be available.
Best Regards
Peter

Hi Chaps
The answer is I now have sourced the bespoke Y cables so they fit Rosetta.
I'm still not sure how may people really want weather in the UK? there are only 5 stations in the South and its seems bit like a facility that no one wants .
Am I wrong is this the Game Changer that some are looking for.
Answers please to help me prioritise

I really think this weather broadcast is a non starter in the UK.
For goodness sake you can listen to ATIS almost everywhere and it's not going to give you the weather at Bogfarm International.
The US is a vast country and people fly long distances where the weather can change dramatically.
In the UK you read the forecasts for a relatively short flight. If it is marginal you are very stupid to continue.
Of course all the pretend airline pilots will want it to go with their stupendously expensive flat screens and try to make us all have compulsory ADSB so they convince themselves they are flying in a fully known environment.
Can't recommend a purchase.
Cheers Bob

I've flown up through France with a friend of mine who has the Golze in-flight satellite weather system. It proved very valuable when trying to see if we could avoid the thunderstorm fronts. We saw that we would be flying through the gaps and that gave us the confidence to continue. An in-flight weather radar picture is excellent. However it is, as stated, more for "getting somewhere" flights than for the local bacon butty run.
I was coming back from France once in my aeroplane, and the way of getting the weather for a few airfields (Shoreham, Oxford Kidlington, um, something else, can't remember, maybe Middle Wallop) while still over the channel was to call London Information and get them to relay them. It would have been a lot easier just to tap on my tablet. Yes, there are only a small number of broadcast stations at the moment, but hopefully these will increase in number, and hopefully there will be some on the south coast broadcasting out to sea!
