Sines... Operation Order CTG 7.3 No. 6-65 f. Commencing at 221400M until 221630M all circuits are to be loaded with traffic for interference test. Where normal (actual) circuit traffic will not accomplish this purpose exercise messages will be originated each ten (10) minutes either by the ship controlling the circuit test or as directed by the ship controlling the circuit test. Tach station on the circuit should be prepared to originate three or more exercise messages on each circuit which is not normally loaded with actual traffic. ge Commencing at 221630M the ship controlling the circuit test originate circuit check-out cach half hour unicss normal traffic volunc 4s sufficient to keep circuit tested or unless otherwise indicated in para 6 below. h.
