This one.

Because it's got no bend in it, I can't have it vertical.

I've got the stubby aerial, which means it's difficult to achieve on the coaming, as I can't put the PAW unit completely vertical.

Would something like this work??

Hi Lee, if you keep making accidental features like this, PAW has a great future!!  ;D ;D

Following on from Bryan's report, something went funny part way through the flight when I appeared to overtake his stationary aircraft, even though he was pulling away from me in front. Positioning is very important, I had it on top of the coaming on it's side, might be better if the aerial was vertical rather than horizontal - thoughts?

Whilst Bryan was within visual range behind I could see him and the SD alarm wouldn't stop going off, his trace was consistently red, which is good, but bloody annoying if you're flying in formation!!

here's a link to my GPS track, something went very funny around Goff's Oak, which is where we both became static on each other's display. Not sure who's device stopped working as expected but it was very strange. Both of us appeared to be moving on track as expected on our respective SDs, but both of us had stopped moving on the other device (I hope that makes sense). Clicking on Bryan's aircraft on SD would show track heading and speed / altitude, but just not moving on the map.

It's only when I looked at the log I saw the issue. We flew direct so I don't know why it thought I was overhead Harlow, as we definitely didn't overfly that area. I rebooted my device once we realised there was an issue, and I only picked Bryan back up during my flare, even though I could visually see him in the circuit ahead of me.

Would be good to get up and test again with more PAW users!

Bryannortje  and I went out to do some testing today. Mixed bag of results, inbound to Turweston I could only see him whilst in the Circuit (his device on the ground). In the air, we had about 4 miles between us, but this is a bit unverified as at one point Bryan seemed to stop moving on mine, and I stopped moving on his - although I was able to see changing speeds and altitudes of his output, it was stuck on the map.

Aside that, we did notice that after a while, instead of showing the ICAO code, we both started showing our registrations on Skydemon. Neither of us were transmitting ADS-B, only Mode S transponders.

If I knew what this meant: aSSRSSIS-58 aMMRSSIM-54 it would help
The -58 and -54 are the received signal strength at the slave and master respectively (I think that's the right way round). I believe that the figures should be in the low -twenties, for stations 30m apart, but  I could be mistaken.  Presumably your stations were separated by building structure at -58 db(i?) ?

So lower is better? They're separated by 1 floor in my house. I'll do some more testing then...

power supply isn't an issue, I'm using more than the recommended kit. 1x 4.2amp wall power supply with .5m juicybitz cable, the other is on a 2.4amp battery pack with the same cable.

Anyone around the Fenland area this Sunday to do some testing?

I mean the one used for picking up ads-b in the PAW system. Sorry, that wasn't too clear.

If I knew what this meant: aSSRSSIS-58 aMMRSSIM-54 it would help, I seem to get higher values without the dvb-t plugged in that when it is in...

I'll do further testing tomorrow with my two units in slave/master config to compare the outputs with and without the dvb-t tuner plugged in.

Just as a complete amateur, this may be a stupid question, but would the tv tuner interfere with the ARF at all?

Is there some kind of testing going on around the middle of the country, fenland perhaps? I've got the plane on Sunday and would really like to participate if possible...

Collisionaware just takes the GPS location and passes it to the RPi (as far as I can tell).

In my main unit config, I have a USB GPS, and then I just connect to the RPi on wifi, Go-Flying with FLARM (as it's called) and i'm way. the GPS dongle knows where it is and the RPi passes everything across the wifi.

I'm using this:

Gives me more stable power than my 22000mah power pack.

hey Richard,

I'll be flying tomorrow with another pilot, not sure which way we're going but we could come your way. Leave it on and we'll see if we pick each other up!

hi Lee,

Was there any update on the testing you were planning to do?

Cheers,

SM.
