Radio Nikkei on 3925kHz is transmitted from both Nagara, Chiba and Nemuro. From April 12 to May 2, the transmitter of 3925kHz at Nagara has been off the air due to transmitter maintenance. Thus, R Nikkei on 3925kHz is now only transmitted from Nemuro. I heard R Nikkei on 3925kHz on April 12, and submitted the reception report. Today I received their QSL - unfortunately they did not mention the transmitter site.
