Contest callsign of OK1HDU

I used a callsign CT9/OK7U during my holiday stay on the Madeira island in OK/OM/DX contest 2015 and 2016.

I used the callsign MM/OK7U in RSGB IOTA contest 2010 from the Mainland of the Shetland archipelago. (IOTA EU-012). You can see an abstract of my logbook together with logbooks of my other activities during that holiday. (MM/OK1HDU/p for SOTA, etc...)
