XSL "Japanese slot machine"

Some of you are probably already using the Sigmira decoder. This is a very nice, free of charge decoder that recently added a new mode to the program. This QPSKmode is better known to many dxers as the "Japanese Slot Machine". The system is being used by the Japanese navy. Sigmira doesn't really decode the information. It only displays the "frames" and raw QPSK symbols. You can download the decoder and its manual from http://www.saharlow.com/technology/sigmira/index.htm

The following is quoted from the Sigmira manual.

"With some investigation the symbol rate was determined to be 1600.00 baud. The regular ticking sound was found to be an exactly repeating sequence of symbols. Clearly that serves as a channel probe and frame synchronization pattern. One tick sound period is here defined as a "frame". Frames were found to consist of 140 QPSK symbols. So the frame rate is 11.42857 Hz. The probe/sync pattern is 28 symbols which is one fifth the number of symbols per frame. It is found that, during the repetitive melody idle time, the remaining symbols of a frame consist of four repetitions of another 28 symbol pattern. So a frame appears to consist of five "blocks" of 28 symbols. During idle time there is a finite set of symbol patterns that appear in the blocks. The patterns are designated here: ps, p0, p1, p2, p3, p4, p5, p6, p7, p8, p9, p10, and p11. The "ps" pattern is the probe/sync pattern. The rest are numbered roughly in the order of their frequency of occurrence. The "p0" pattern is most common. The melodic idle time consists of an exactly repeating sequence of 64 frames. A 64 frame sequence is called a "super frame" here. The duration of a super frame is 5.60000 seconds. The frame / block pattern of the idle super frame is presented in the following table. The melody arises from the regular repeated simple patterns of symbols/phases. The p10 pattern is all one phase. So it produces a single tone. The p11 pattern is also all one phase but 180 degrees from p10. The other patternsare somewhat more complex and result in different and multiple apparent tones."
