What is good amateur practice if propagation changes during a contact creating interference from other stations using the frequency?
Advise the interfering stations that you are on the frequency and that you have priority
Decrease power and continue to transmit
Attempt to resolve the interference problem with the other stations in a mutually acceptable manner✓الإجابة الصحيحة
Switch to the opposite sideband
الشرح
Since no station owns a frequency, an interference problem created by changing propagation is not settled by asserting priority or by talking over the other station. The accepted response is to negotiate, which usually means one side moving.
