This test is often run when establishing a reconnection between two stations. The sentence contains all letters and numbers. The ryryr line is used for testing the correct speed and synchronisation. ryryr represents the maximum of changes. this means 01010 10101. when this is decoded clean the possibility of establishing a good connection between two stations would be nearly 100.This was very important as mechanical typewriters were used. The speed is 50Baud or 50Bd. |
