Technical Support / Re: Wiring into Trig TT21 - is it worth it?

Hi Peter

Thanks for that - I have got a little Eurostar .......

Hi Altomar,

You don’t say what type of aircraft you fly. The external antennas are of significant benefit if the aircraft is metal-bodied as they get the signal out in the clear away from potential obscuration.

I have also been using them under the pod of my flexwing (with a thin laminated aluminium foil ground plane inside the pod) for some time now to very good effect - especially the 869.5 MHz P3i one. If using both, be careful to keep the shorter 1090MHz one as far away from your transponder antenna as practicable to avoid potential interference (not so easy in a flexwing).

I also echo the others’ comments re connecting to your transponder. It’s a fairly simple and inexpensive job, using a single USB to RS232 Serial Adapter Cable (obtainable from RS Components or Farnell for under £30), and ensures that you will comply fully with the CAA recommendation that we all ‘transmit ADSB on 1090MHz’, so is in my opinion a ‘no-brainer’. If you need any help or advice, feel free to ask - I have done several.

Regards

Peter

Hi Crash,

Thanks for letting us know. Get back in touch if you have any more problems.

I did fly over a couple of times before the travel restrictions came in, but there was no-one about, so didn’t land. I will try again if/when they let us travel back to East Lothian again.

Best Regards

Stay Safe

Technical Support / Bluetooth Audio
« Last Post by neilld on November 26, 2020, 08:49:07 pm »
Tried my new (half price) Rosetta to-day using audio alerts via Bluetooth. Seems to work OK but:-
1. Do I have to "pair" the Rosetta with the BT receiver every time I use it or does the PAW "remember" the BT connection?
2. I found that the pairing process took some time and several attempts to find the receiver despite being close to each other.  Is this normal?
3. The search for nearby devices found a number (including my mobile phone).  Can I stop the PAW from trying to pair with the wrong device? (When I tap the "connect" icon, all the found devices seem to try to connect)

Tried today. Everything perfect.
I think either Flarm TCP and or repositioning did the job. One target disappeared for a few mins as me and the engine got in the way of line of sight.I‘ll fix a bracket on the bulkhead as high as possible with the unit level and right side up.
Quite happy. Thanks for the help guys.

My understanding is that TCAS in CAT is triggered by the other aircraft's transponder and not its ADS-B Out data.
Future upgrades in TCAS technology may process ADS-B Out data for TCAS purposes, but will always process transponder data from your certified Trig TT21.
As other posters have said, definitely go ahead and make yourself ADS-B Out visible.

You're right, brain fart on my part as TCAS interrogates the transponders around it...

This is available on the PAW website, hence my comment about external antennas :- https://www.pilotaware.com/product/aviation-grade-external-antennas

I agree with Paul. It certainly is worth it.
It's cheap and simple to do.
There will be other traffic out there not PAW equipped but with ADS-B in on another system so they will see you.
You don't need another antenna. You must have misread something.
Good luck.

General Discussion / EC Rebate - thoughts, time scales, etc...
« Last Post by steveu on November 25, 2020, 09:41:10 pm »
Hi all,

My EC Rebate has been approved for my PAW.

I signed up for a Portal Account in October. I waited until the PAW was invoiced then went through the ID verification, which took longer than expected, roughly about a week due to their workload, they say 2-3 days. As soon as I had the invoice & ID verification complete, I applied for the Rebate on the online form, it has taken just over two weeks for them to process.

Sorted and happy with that...

I think it's important to mention screening.

Certified stuff may screen out ADS-B from a source with uncertified GPS, i.e. SIL = 0. Or you may be seen but not trigger TCAS. So, you won't necessarily pop up on every ADS-B in system, and the CAA agrees with this conclusion, having echoed it in their EC grant application backgrounder.

This is a point worth raising but does not alter the advice given to make the connection with the cable, set up the TT21 as per the Trig instructions, and enjoy the benefits of being seen by more aircraft.
