These broadcasts are less common than X06 as well.  (scale ex. 121212)

X06b

X06b is a variant where one tone is used longer than the others
in the pattern.  Although it usually has 5 tones, 6 can rarely be
heard.  X06b is much more rare than a typical X06 broadcast.

X06c

X06c is a variant where the tones constantly repeat in a rising pattern (only 123456).
