I am not sure why the LAT / LON or the source address of NRT are so screwy but that is what I received.

Hi Jim,Interesting catches.So far we have only seen sources addresses that start with 1 or 2. The value indicates the operator, either SITA or ARINC. Keep forgetting which is which.

So the question is what the F source adresses are used for.

As the messages you posted are short I wonder if this is all you logged or if you posted only parts of the messages.If this is how they where logged you moght not have enabled the "XID" details option (button) in MutliPSK.Can you confirm that?

With this option enabled you get more details which could give a clue on who this ground station is.

73, Dick

Hello Jim,  TKS for the reports. However the data is not complete (as mentioned by Dick).In particular, it misses a line as Airports covered by the ground station: EFHK HELSINKI/VANTAA (FINLAND)   73Patrick  De : multipsk@yahoogroups.com [mailto:multipsk@yahoogroups.com] Envoy. : mercredi 6 janvier 2016 13:19. : multipsk@yahoogroups.comObjet : [multipsk] Re: New VDL2 squitters

That is the whole frame as captured.

Well, considering I was sitting in Narita Airport when I made the captures, and this is the third time I have done this, on 3 different occasions, all with the same results I feel it safe to say it is Narita Airport.  Again, look at the LAT, LON.  Any idea whey the are off by so much?  Narita is at N 35. 45.9' E140. 23.2'.

I just checked and the XID details button was not depressed.  Next time I go through it will be.

Hello,  The location given is wrong. I decode from your data and it gives this. I don.t know why they send such position. However, you can note that this position is 1/10th of the real one (3.5 for 35. and 14 for 140.). It is perhaps a configuration error (a .0. missing) from the Narita operator....  73Patrick  Public parameters:HDLC public parameter: 8885:1993Classes of procedures (hexa): 0001HDLC functions (hexa): 208480I field length TX (hexa): 07D8I field length RX (hexa): 07D8Private parameter set identifier: VAVLC specific options parameter (hexa): 20Airports covered by the ground station: NRTBATN router nets:. * ADM identifier (hexa): 000000..
