DO means “from here QOD6 starts” and SN means “QOD6 has ended”. Many Japanese CW stations using Wabun are on the air especially between 3515k Hz and 3525 kHz, 7015 kHz and 7025 kHz and around 144.070 MHz.Ī marker of Wabun is DO and SN. Both 80 mb and 40mb are so suitable to contact with stations all over Japan, from Okinawa (JR6) to Hokkaido (JA8), and 144MHz band is for radius of within 150km. The Wabun CW QSOs are popular in 80mb and 40mb, plus 144MHz band, because of the characteristics of the propagation. The first type is “599 BK” style, the second one is chatting using QOD1 (in English) and the third one is chatting using QOD6. In Japan, it seems that there are mainly three types of CW QSOs. If remember Wabun morse code (QOD6) it is easier for Japanese CW men to send what they want to say and to hear what the other stations want to say because Wabun communications are done in their mother tongue. According to “Directory of Wabun CW Stations”, published in August, 2013, by an amateur society of Wabun CW fans, there are around 3900 amateur radio stations operating Wabun CW in Japan. The reason why I like Wabun CW QSO is that we can communicate with in Japanese language even in CW mode. “Wabun” means “Japanese language” in Japanese generally and “CW communications in QOD6” especially among Japanese HAMs. I like to QSO using QOD6, the Japanese Morse codes, so-called “Wabun CW”. “WABUN” – THE JAPANESE MORSE CODE (QOD6), MAI, JH1JDI – FISTS #15123
