Listen to an unidentified station on 6220 Khz at 1724 Utc with SINPO 32432. Massive interference by TV-set. At recheck at 1740 Utc unheard. Plays some pop-music. Heard again at 1755 Utc with classic rock. I doubt it is Mystery Radio. Might be two different stations. Till 1920 Utc only nonstop classic rock and pop-music without announcement and jingle.
