Question 6A601

When transmitting a routine radiotelegraph (CW) call to a specific station, the standard and efficient procedure is described in option B. The calling station transmits the call sign of the desired station, typically not more than twice, followed by the prosign "DE" (Morse for "from"), and then the calling station's own call sign, also not more than twice. This minimizes on-air time while ensuring clarity. Option A is incorrect because "CQ" is a general call to any station, not a specific one. Option C is incorrect; amateur radio operators do not require permission from public coast stations for routine communications. Option D is also incorrect; while service abbreviations are used extensively *during* CW contacts for brevity, the initiation of a call to a specific station follows the established call sign "DE" call sign format.
