The March equinox is actually the seasonal peak for certain propagation paths. My one and only Top Band QSO with 9M2AX occurred in late March a few years ago (at my sunset). The path to 9M2 stayed open until the first part of April that season, before we ran out of common darkness. Just tonight I heard Ross a short time after my sunset and a few minutes before his sunrise, although strong static crashes made copy difficult on this end.
