??战争或警匪片中常有运用收发两用无线电台或对讲机的景象。这个设备与电话不一样，联络两边要轮撒播闻，而不能一起进行，所以需要术语协助交流。其间一些已进入往常言语。
常见的术语包括：
This is：放在对方称号之后，用于介绍自个，意思是“某某，我是某某”。如，“Mother Goose, this is Messenger 
Pigeon, over.”
Come in：You may begin speaking now。意思是“请答复”。如，“Contact C. This is L. Come in. 
Over.”
Go ahead/stand by：意思是“收到，请讲”或“收到，等候”，用于回答对方呼叫。如，“Adam, this is Mike, Go Ahead. Over.”
Read：I hear a signal clearly enough to be understood。意思是“收到”。如，“Do you read me? Over.”
Roger：I have received all of the last transmission。意思是“收到”。摩尔斯电码无线电报年代，为节约时刻，创造了缩略语，包括用R标明“received”。到了语音通话年代，这一传统得以保存，但运用了读音字母表，比方“alpha”代表A，“bravo”代表B，而“roger”则代表R。
Copy：意思是“收到”，但不是标准用语。前期无线电操作人员可以需要书写或打字来记载信息，发生这一习气用法。如，“Messenger Pigeon for Mother Goose. Do you copy? Over.”
Over：I have finished talking and I am listening for your reply。它是“Over to you”的简写，因而“over”不是“结束”的意思，而是“该你了”或许“收到请答复”。每说完一句话要用“over”结束，以提示对方答复，直到最结束束通话。如，“Mother Goose, this is Messenger Pigeon. Over.”
Say again：意思是“请重复一遍”，用于没听清对方的情况。
Out/Over and out：I have finished talking to you and do not expect a reply。意思是“本次通话完崩淠在“out”之前加上自个的称号。非正式情况下，也可以用“over and out”。
Loud and 
clear：意思是听得很理解。
Affirm/affirmative：必定答复，比“Yes”理解。
Negative：否定答复，比“No”理解。
例1，C21A（Charlie-two-one Alpha）呼叫C33B（Charlie-three-three Bravo）：
C21A: C33B, this is C21A, message, over.
C33B: C33B, send it, over.
C21A: Have you got C1?D Sunray at your location, over?
C33B: Negative, I think he is with C3?C, over.
C21A: Roger, out.
例2，Adam呼叫Mike：
Adam: Mike, this is Adam. Over.
Mike: Adam, this is Mike, Stand By. Over.
Mike: Adam, this is Mike, Go Ahead. Over.
Adam: Mike, there is a fire at 123 Main St. Over.
Mike: Adam, this is Mike, confirming a fire at 123 main St. The fire department will be notified. Over.
Adam: Mike, this is Adam, address is confirmed, thanks for the help. Over and Out.
