2. IFC DE NKF
You are correct. Station IFC calls station NKF. The procedure signal (prosign) "DE" means
FROM or THIS IS, and is used by the transmitting station to separate the two call signs. When
station NKF replies, he becomes the transmitting station, therefore, he replies IFC DE NKF.
Be sure you understand the DOUBLE STATION call before continuing with the instruction.
3. The second type of specific call-up is called the SINGLE STATION CALL. In a single
station call, the transmitting station uses only one call sign. It may be the call sign of either
the transmitting or the receiving station. Figure 3-2 is an example of a single station call.
