Hi Ian,
After I received the document I phoned the chap up in Germany and quizzed him on the minimum version as it conflicted with advice others had been given that had been shared with me.Ours appears to be too old to upgrade - funny as it basically seems to work !!
If, by "basically seems to work", you mean it outputs SIL=0 and SDA=0 then that may well be true.
However..... I was advised by NATS that a couple of transponders in their uncertified GPS ADS-B trial output faulty GPS position coordinates (flipped minus sign on LAT or LONG). And the Funke chap on Friday said that there were bugs in the pre-v5.3 code to do with intermittent faulty GPS position. I put 2 and 2 together!!!
As I now understand it, Funke started providing support for ADS-B from v4.8 onwards but 100% correct support for uncertified GPS ADS-B is only from v5.3 or later.

ok here is a question:
So I'm flying and outputting ADS-B through transponder and have my PAWS all up and running. I fly towards say Ian Fallon and he is doing the same thing with ADS-B and PAWS. If we are out of PAWS range I would expect that we would see each other on the ADS-B receiver input.....so if we fly towards each other what will happen when we get to within PAWS range ??
Hi Bryan,
This is a valid point, because the data that is held is consolidated from the P3I and ADS-B streams.
The index is the ICAO Hex code, so if the data is interleaved like this as it is received
ADS-B ...
ADS-B ...
ADS-B ...
ADS-B ...
P3I ...
ADS-B ...
P3I ...
ADS-B ...
P3I ...
What should be displayed ?
Thx

Presumably the combined data will produce a single aircraft icon showing relative altitude etc as if it is from a single (i.e. either) source. Not sure we need to know the source type - surely the object is to encourage us to look outside for the approaching aircraft and to help decide which way to turn/climb or descend to pass it clearly and safely.
Data can be examined later if necessary through the traffic screen if I recall.
I do accept though that during the extended testing period a simple means of determining whether the contact is from an ARF source or a much higher powered ADSB unit could be beneficial.
