Curious short-wave transmissions

Miniature tweezers for SMDs
Radio listeners will no doubt have hit upon one or two stations where the programme content is made up entirely of someone (usually female) monotonously reading out a series of numbers. Your first assumption may be that you have gate crashed a pirate radio version of Bingo until you notice that some of the numbers are repeated and grouped either in fours or fives.
These strange broadcasts have not only attracted the attention of shortwave enthusiasts but also songwriters and filmmakers… not forgetting government counter-intelligence departments.
