Every radio operator must know it by heart. Many know it from Kinofilmen. The spelling tablet! Created to prevent misunderstandings. In the beginning partly also confusing, so was inserted in the first Berlin telephone book a spellbill, in which the letters were numbered. So A was one, B two, etc.
Nowadays, spelling tablets also exist in different versions, the most common being the NATO tablet, if one is to spell tofu is that:
Tango Ocar Foxtrott Uniform.
Now finally the spelling board for the barbecue friend, Tofu is here too:Tomahawk Obatzta Frischerfisch Ungrillbar…
Ad your two cents!
