Somebody on twitter pointed out that – · – · – – · – – · · (aka CQD) is the distress signal sent when the Titanic sunk. Maybe this is what those three letters amount to?
This sounds very solid. The morse code from the tweet, Titanic=999 and it would also fit with what will
happen in Nevada
from Wikipedia
Thus, "CQD" is understood by wireless operators to mean, "All stations: distress." Contrary to popular belief, CQD does not stand for "Come Quick, Danger", "Come Quickly: Distress", "Come Quick—Drowning!", or "C Q Danger" (Seek You, Danger)
