[CW] Ship Radio Room clock

[Richard Knoppow]

    Different clocks for different purposes. The clock for crypto 
was probably an atomic clock or at least a crystal clock of some 
sort, while the radio room clock is a reference clock and does 
not require high precision. Same for navigation, I suspect atomic 
clocks have been used for decades, at least prior to satellite 
clocks which are virtually absolute.
