Notes: Stations NAN and UNCLE existed concurrently 10 December 1950 to 21 June 1953 along the SF-Hono route.

The international phonetic alphabet was changed thus the confusing station names. NAN became November, PETER became PAPA, etc.

In 1947 all ocean stations were assigned radio beacon identity signals with the preface 4Y plus the station name. In practice the 4 was dropped and the beacon signal consisted of Y, station identifier and two letters to indicate the particular square that the ship occupied in the 200 mile grid. (OS being the center square) Thus a ship on center square of station NOVEMBER would transmit (continuously) YNOS
