Ten records that had been carrying FM in submodes moved it into modes in the same commit.\n\nTwo legs on one record: both run 10:00-13:00 UTC and differ only in their anchor, and the anchors are different SHAPES -- the second Saturday of June and the LAST Saturday of October -- which a composite holds without trouble.\n\nSARL explains the timing: 'The dates are three weeks after the RAE Radio Amateur Examination', which is why the contest is aimed at newly licensed amateurs.

The SSB dates fit nothing at all -- the FIRST Saturday of November, then the FIFTH Saturday of October, then the FOURTH -- not even the same month twice running.
