My log has a QSO with Dima back in February 2018 when he was on a radical DX adventure in the desert to a "no-mans-land" territory, which he then claimed and declared himself as "King", and self-assigned the call sign 1U4UN. Hope I get a QSL; could be a conversation piece some day. https://www.qrz.com/db/1u4un https://dx-world.net/operations-at-1u4un/ Despite claims otherwise, it appears the Bir Tawil zone is under dispute by some in Sudan and Egypt, both tumultuous. I would bet this alleged detention may have had something to do with that excursion. https://en.wikipedia.org/wiki/Bir_Tawil
