I think you met a station with that callsign.  (D1DX; D1DNR; D0IBM; D075EN; D075P; D0IAU; D0IVU; D1A; D1ACW; D1AO; D1CTT; D1WA; D1WW; R6KD ect) – ALL THIS STATION are pirates!

 These stations operate from the territories temporarily occupied by Russia, the Ukrainian Donbass.
 Donbass is a region of Ukraine that was partially occupied by Russian terrorist groups and the Russian regular army in 2013.  In the same year, Russia occupied the Ukrainian Crimea. 

Now callsigns are issued there R6 (7) K ** or /5 

These stations are not recognized by the world community and are not included in dxcc. We kindly ask you not to work with these stations.  The operators of these stations are separatists. Real patriots continue to work with the old Ukrainian call signs from these regions. 

Stations D(0)1***, R6(7)K **, R ****/5 are pirates, people with a terrorist bias, who hate the European and world community, and show aggression towards the inhabitants of Ukraine.
