Orson, I think there are two elements to be coded: the four letters to be transformed into representations of appropriate semaphore letters and the ninth row (ICED WALKS NORTH) to be replaced by a Morse code representation of a name common to both S&A and Nansen's expeditions. It is this that is causing the 6,6 and 6,5 discussion, as the vessel Fram codes to six dashes and five dots and no-one so far - unless saoralba has cracked it; I have not had a PDM on the hint offered - has come up with a satisfactory 6,6.
