For those unfamiliar with the VTN (Vietnamese Numbers Station) information can be found at my web page concerning the stations, URL
http://token_radio.home.mchsi.com/VTN.htmThe VTN has been pretty steady this past month, near daily transmissions, as normal 3 identical messages a day starting at about 1600. At the beginning of the month the message was a 30 group message read by a female voice. The last of these YL/5f/Vietnamese/30 group messages was noted on May 10, 2011. No message was received May 11, 2011, and starting May 12, 2011, a new content message was sent, again three identical messages each day starting at about 1600. The new message was sent by a male voice, in Vietnamese, and consisted of 50 groups, each of 5 figures.
