Hi lcdrusnret,

The grid didn't change but during the course of the war they came up with an "Address Book" which was used to double encrypt the grid references in radio transmissions instead. Most of the time the grid references in the KTB are in the clear but sometimes they entered the encrypted grid references in the KTB instead. Anyone reading a KTB might find a grid reference that didn't make sense & assume they changed the grid map but they didn't. Reissuing all those grid maps would have been a monumental pain in the butt. That's why they came up with the "Address Book". The technique used to double encrypt the grid references also changed over the course of the war from simple to pretty complex.

Regards,

Ken Dunn
