Watched the 2013 spy thriller The Numbers Station on blu-ray. It is based on the spy worlds theoretical use of number stations. John Cusack stars in the movie as things go awry for the code operator he is guarding at one of these stations. It is very good film that I give 3.8 of 5 stars.
The Lincolnshire Poachers station is British Secret Service run and here is one of the actual broadcast codes.
