1602 have many low power NHK2 stations. One of them is JOSB from Kitakyushu in Fukuoka Prefekecture with 1 KW. JOSB is one of the more common NHK2 on 1602. Nice QSL letter, photos and postcards verified my report today!
AFN Misawa 1575 is not as common as 810 but on the 15th December 2017 I heard them with a good signal. They split up from Tokyo with local Misawa info at 12:18 UTC. E-mail with attached PDF QSL from the Misawa HQ verified my report. Once again, thanks BM for v/s info.
