Radio Nikkei 1 (Japan)

Radio Nikkei 1, transmitting presumably from Nemuro, Japan, was logged on (Friday only) 30 November 2012. A programme of traditional Japanese music with discussion and station promotions  was observed from  10.30 to 11.00 UTC. Transmission was on 3.925 kHz. Reception (SINPO) was 35443 -- fair signal strength with  some atmospheric noise, otherwise good clarity of audio.

Radio Nikkei 1 was previously QSLed on 9.595 kHz. This frequency, transmitter location and transmitter power is supposedly different, and hence the interest. As it turns out, the transmitter output is 50 kW, the same for the other Radio Nikkei frequencies; see the reverse side of the QSL card below.

Radio Nikkei  1  broadcasts on 3.925 kHz from Nagara, Chiba (call sign: JOZ) and from Nemuro, Hokkaido (call sign: JOZ4). They are synchronised regardless of the day of the week (when Nemuro transmits).

The Nemuro transmitting station (which was in Sapporo before 1996) was established for the purpose of anti-skip in the metropolitan (Tokyo) area in winter and at night.

According to Aoki's list, the schedule for the Nemuro site is as follows:
- Evening in Japan  (Monday-Thursday) 08.00-13.30 UTC, (Friday) 08.00-14.15 UTC, and (Saturday and Sunday) 08.00-12.00 UTC;
- Morning in Japan (Daily)  22.25-23.00 UTC.

Reception report was emailed and submitted on-line. This QSL card arrived in the mail on 14 December 2012.
