This signal is transmitted almost "as is" into the air, and the backward process of decoding is activated on the receiver side. The message length is 15s, and messages are transmitted via fixed time slots, which makes decoding easier. Some of the data that are collected include the number of visitors, their source, and the pages they visit anonymously. A +12 signal does not say how much power a person is using. If this is the case, then you probably have signal distortion in audio output. FT8 handles very weak signals very well, meaning that a Foundation licence holder with just 10 watts should be able to make some impressive contacts with a modest antenna - something not possible with voice or some other data modes. We are trying to coordinate the suggested frequencies in WSJT-X with updated band plans being considered by IARU, ARRL, and other amateur radio societies.
