Q) When is an amateur station required to transmit its assigned call sign?
A) At least every 10 minutes during and at the end of a contact
NJ2X Note:
Some amateur radio operators use a timer to help remind them to transmit their call during the course of a contact. When making contact with another amateur radio operator over a repeater, some hams simply transmit their call immediately following the repeater transmitting its own call (using it as a 10 minute reminder).
