Peter,  I learned my lesson and kept the PAW unit here on my desk!   Here is the screenshot.   By the way, I have updated the software on a fresh SD card, but I put the old SD card back in for the purpose of taking this screenshot, so it would be on the old software (just to reduce the number of variable).  thanks, John

Peter,  Yes, that's right, the GTX 328 is a mode S, non-ABSD transponder (incapable of being upgraded to ADSB - don't get me going!).   It is programmed with just the HEX code in (I uploaded a photo previously).

The question for me is "what has changed".   I have flown, probably well over 100 hours with the PAW set up like this with no problem) then suddenly I get this problem.  Since nothing in the aircraft has changed, I initially assumed it was something external. The answer might lie in the following:

Lee,  there problem was the last time I flew the plane.   There is no track file for the flight.   There is a file for the previous flight and files from when I've been recently fiddling around with it on the ground, but nothing for the approx 90 minute flight where the ghost appears.  Weird!

I'm not sure we are going to get much further.  Why don't we wait and I'll report back when I next get to fly (although that could be a while)?  thanks everyone, I'm very grateful for the help, John

Hi Peter,  Yes, both GPS antenna were connected at the same time (all 4 USB ports on the PAW were in use).  This stems from me being confused and thinking the larger one was a Flarm antenna.  I will remedy that before I fly again and hopefully that will be it sorted.  Thanks to everyone for the help!   John

All,  Thanks!

Peter, Sorry for disappearing (I've been distracted by something else since Monday).   The original PAW GPS dongle (that looks like a datastick), is connected to the PAW by a USB extension.   When I pull the extension out of the PAW, it loses position.   Maybe if I booted it up with that disconnected, it would 'find' the one that looks like a mouse.   I will try that when I put it back in the aircraft.  I've also done the sortware update, so hopefully  one of these changes will fix it.   I confirm there is no other EC on board apart from the Garmin GTX328.  It looks as if it's going to be a few months before the next flight, so the acid test will have to wait for a bit I'm afraid.   I've just ordered a Skyecho, so I'll have some fun setting that up too.

Thanks for the help, John

I've been to the plane and disconnecting the 'mystery' mouse does NOT cause loss of GPS signal.   It is stuck down and I'm reluctant to pull it off, so I cannot read what's on the underside.  Disconnecting the small dongle that looks like a datastick does cause loss of GPS signal (and before I sprayed it black, it had the words "GPS/GLONASS" written on it - I know because I've got a spare)!   However I also found a 2017 receipt from Pilotawarehardware for a "GPS Mouse on 195cm lead".   So I am thoroughly confused now.  Perhaps I got two GPS receivers, and when the kit arrived and I saw "GPS" written on the dongle and just assumed the other was the Flarm dongle I had wanted (and thought I had ordered).  I cannot find a receipt for a Flarm dongle however, so perhaps I don't have one and I just confused the debate by mentioning it. 

In which case we are back to the drawing board.  All offerings welcome please? 

Also (James), the track file for the problem flight (on the 4th November 2020) is missing from the list (on the screenshot).   Maybe PAW just failed that day for some reason.   (It does have a good Anker power supply, so that's not the reason.)  I've just done a software update today, so maybe that will help in future.

Peter, Ian, Lee,

My understanding has always been that's the Flarm mouse in the photo.  I certainly ordered one (in December 2017, Order number 1819)!   The GPS receiver looks more like a USB stick.   You can seem them both in this other photo, with the mouse on the left and the GSP receiver (which is painted black to stop it reflecting in the windscreen) on the right.   I could have completely misunderstood however. 

I just checked the instructions I used to set it up (20170721) and I don't see anything in there about programming the Flarm mouse with a Hex code.  I've never been very clear on whether it was a Tx/Rx or Rx only.   I certainly didn't set it up in any way, I just plugged it in.

If the consensus is its actually a GPS receiver, then I seem to have two.   Otherwise, if it's a Flarm Mouse, can you please point me to the instructions on how to enter the HEX code?   

If there is still uncertainty, I can always unplug it and see if I lose the GPS signal?  The plane is hangared at home, so I can do that faily easily.

Thanks, John

Hi Peter,  Thanks for your response.  I'm afraid I didn't notice if the relative position of the ghost changed slightly during the flight, but it was "on top of me" the whole time.  I probably should have fiddled with it some more at the time, but in an unplanned situation I tried to force myself not to get distracted by it too much.       

I always get the 3Pi and ADBS-in antennae confused in my head, but if I've got it right, the 3Pi antenna is on the right underside of the fuselage, just aft of the main spar, and the transponder antenna is on the left underside, aft of the back wall of the baggage compartment (and they are 1.3 meters apart).  The ADBS-in antenna is in the cockpit, on top of the turtle deck facing the sky and there is a flarm mouse right next to it.   The setup has been like this for over two years with no problems.  It's a classic PAW and it's mounted by my left knee, so next time I fly I should be able to pull out each USB in turn to see if that makes a difference. 

Given your response that it's not MLAT, what is really confusing me is that I'm not getting the problem on the ground.  I attach a screenshot taken this morning (the contact is my ground station).   The HEX code in the transponder is definitely correct, I even took a photo so I could convince myself afterwards I wasn't going mad! 

There were no other EC devices on board.   I've been trying to decide between upgrading to a Garmin GTX 355 or just get a Skyecho, but I'm a bit nervous of compounding these sorts of problems if I go for the Skyecho. 

Thanks again, John

Hi,  Can someone tell me please how to fix this ghosting of my own aircraft that appeared on a flight in November (I hadn't changed anything from before).   It followed me right across the country and pretty much prevented me from noticing any other aircraft.    I attach a couple of screenshots from Skydemon.    The aircraft transponder is a non-ADSB Garmin GTX328 (mode S) and I have checked the HEX code on both that the PAW unit are correct.   I can only presume the PAW is somehow receiving MLAT information with the aircraft ID missing?

I didn't think at the time to try turning off the transponder and a soggy runway has stopped me flying again since.   I turned it all on again today in the hangar (as it happens with a PAW ground station just 50 meters away) and the ghost wasn't there, which is what makes think its MLAT.    My PAW is a classic unit set up as a perminant installation with external antennae.

I want to sort it before I spend some serious dosh on an ADSB out solution,

Thanks, John

Just to say thanks to everyone who responded.  Dave Styles sent me a replacement Wifi dongle and with that installed it all started working straight away,  John

Eric,  thanks,  I’ve just tried that, but it still doesn’t work.  I must say, i was a bit relieved,  I dont fancy adding that to my prefilight checks.   I assume one of the bits of kit is a duffer so I’ll contact.  PAW in the morning.   Regards, John
