Flags. Semaphore, Radio Speak, and Morse Code Brief GuideA Seadolby Reference PageA one page quick guide to maritime semaphore, morse code, radio speak and the flags as found and used today and yesterday within the merchant navy and shipping industry. There is so much more to each system/code but I present here only the bare bones, as a quick reference or introduction only. Use and enjoy but for greater accuracy I suggest that other sources are found. |
