Sign your call sign once, followed by the words “listening for a call” -- if no answer, change frequency and repeat

Repeat “CQ” a few times, followed by “this is,” then your call sign a few times, then pause to listen, repeat as necessary✓پاسخ درست
Transmit an unmodulated carried for approximately 10 seconds, followed by “this is” and your call sign, and pause to listen -- repeat as necessary
توضیح
The standard general call is CQ repeated a few times followed by your call sign, then a pause to listen. An unmodulated carrier identifies nothing, QTC announces that you have traffic for a specific station, and a single call sign with no CQ does not signal that you are calling anyone.
