Perhaps related, but when communicating over the radio (including via digital printing modes like RTTY) you have to declare that you’re done transmitting and yield the frequency to the other party. This is because your signal may fade, appearing to the other person like you stopped transmitting. This is the purpose of the ubiquitous “over” seen in movies and TV, though in ham circles you use the more casual “go ahead” or “back to you”.
I imagine a period sends the same message, but because you don’t have to manage turn-taking with texts the way you do on the radio the period can be seen as redundant because they already know you’re done speaking. So sending a period may seem like you’re emphasizing the finality of your message.
In radio, you signal the end of a contact (QSO) with “out”, but again, in ham circles you just say “73”.
Is any of this relevant? I have no idea I’ve been up since 1 AM this morning.
