From now on, all applicants from Crimea will receive call sign from swarl according to the country stated in application. If the country is Ukraine, prefix will be UU1 if country is Russia the prefix will be RK7.
All applicants should keep in mind though that Crimea is officially part of Ukraine DXCC and RK7 prefixed calls may have difficulties with recognition in some international award programs. Those who wish to change their Ukrainian Crimea prefixed call to Russian, welcome to contact me.
