Today was a slow day, I’m the middle of an NDB “contest” that doesn’t bring much sofar…(more about that tomorrow). So time to dig into my QSL collection for something special!

In those days maritime stations were broadcasting CW markers which made long distance reception relatively easy despite limited transmitter power.
