Excellent conditions towards Okinawa brought these two NHK-1 Okinawa stations. The Gabu, 531 station is only 1 kW. Oddly enough, they gave their local ID at 16:01 UTC, and closed down, contrary to other NHK-1 stations. Thanks Ole Forr for spotting this. A friendly letter accompanied the QSL card. Their NHK-2 station on 1125 is already in my collection.
