Use of FCC Call Signs when Tactical Call Signs Are Being Used

A. There are three primary cases, based on which pro-word is appropriate at the end of a transmission.

Case 1. "Over "if they expect the SNC to reply immediately.  In this case the FCC call sign is not required.  (Note: As discussed below, "How copy" is equivalent to "over".)

Case 2. "Out" if they don't expect an immediate reply.  In this case it's safest to give their FCC call sign just before "Out" because they don't know how long it will be until they'll speak again.

Case 3. "Clear" when they are turning off their radio or changing frequency.  In this case it's mandatory that they give their FCC call sign just before "Clear".

B. During an exercise when a controller may be giving feedback, when should a FCC call sign be used after voicing a NET Form 8 or ICS Form 213?

If they're not sure that you will be giving them immediate feedback, case 2 applies.  But if they say "How copy" then that's an implicit "Over" and they are expecting a reply so no call sign is required (unless the message took 10 minutes to read).   Here's are three examples;

a. ARO: End of message. How copy?

   SNC: Roger your message 8.

  ARO. KK7ABC as South Heights Out.

b. ARO: End of message. How copy?

  SNC: Please fill between "Jack jumped over the" and "stick".

  ARO: I say again "candle".

  SNC: Roger your Message 8.

  ARO: KK7ABC as South Heights Out.

c. ARO: End of message. How copy?

  SNC: Message received completely but I recommend you use longer pauses after long words.. Other than that, nice job.

  ARO: Understood. KK7ABC as South Heights Out.
