MARCONI EXPLAINS
In an effort to determine whether the signal "C. Q. D." might not have been misunderstood by passing ships, Senator Smith called upon Mr. Marconi.
"The `C. Q.,'" said Marconi, "is an international signal which meant that all stations should cease sending except the one using the call. The `D.' was added to indicate danger. The call, however, now has been superseded by the universal call, `S. O. S.'"
