Give it a rest Gaz, it's getting rather tedious.
Because it takes a while to get after the real facts?
So I had a re-read of @leemoore1966’s post (thanks Lee, I get what you are saying now) and can see that the latest build Stratux EU can act as an airborne OGN receiver - from within that OGN capability comes the ability to receive FANET, FLARM, OGN Trackers and P3i. Further, a Beta is ongoing to build a transmitter that Rosetta can receive using an 868 TTGO T-Beam board fitted to enable transmission, too. But there is quite a bit of effort needed to get in-use Stratux boxes in the EU to do this as I understand it? But it is a very interesting development as it looks like if you build the latest Stratux EU box then you get a receiver that sees almost everything without the use of ground stations (hallelujah!):
1090 ADS-B
978 UAT FIS-B/TIS-B
Mode S bearingless warnings
OGN capability to detect FLARM, OGN Trackers, FANET and P3i
So that is pretty much a full-house on all of the protocols for receive only. As a self-build device then it would be unlikely to meet the Declaration of Capability and Conformity (DoCC) with the CAA to have a transmit capability on 1090Mhz below 40W. But if it did, and it was packaged up into a robust design then it would meet the “Holy Grail” of portable EC devices. As it stands, then only “Build 3” variants of Stratus EU transmit, and even then they appear to be transmitting P3i, so not very many detect that signal standard - so you still need an ADS-B enabled transponder or a CAP1391 transceiver to be seen by the majority of other air users.
Thanks for pointing to this interesting development - I wonder if FLARM will stay silent on licence-free airborne detection of their signals? That will be in addition to SoftRF, which was a smaller enterprise. But it then begs the question why some of us are paying FLARM for a licence fee to decode FLARM signals within our chosen electronic flight bag software, when others are not! We’ll have to wait and see how that plays out, I guess?
[edited extra] It might be more transparent to state this with my highlighted extras:
Every OGN station in Europe can be modified to detect PilotAware
Every Atom station in Europe detects PilotAware (although there aren’t that many in continental Europe yet)
Stratux EU can be modified to detect PilotAware
SoftRF detects PilotAware
