RaRadar thanks,
The European Mode S Station Functional Specification is a very interesting document. Since it preceded the AeroThai document by about 7 years the Thais were probably aware of it.
Like you say most or all European radars probably comply with the specification. The interesting question is whether countries with a tight budget and looking for a cheap deal may buy non-compliant radars. In other words whether there are companies that produce cheap non-compliant models.
The EASA document being published about 6 years after the specification seems to suggest that even compliant radars may suffer from ID duplication effects.
