We started to build a small audience. When Morse code operators sign off, they often use a quick signature borrowed from the classic vaudeville jingle of closure. One station sends (in Morse code dits) "shine and a haircut" and the other station replies "two bits" (dit dit.) When other stations were listening in, they will also sign "dit dit" to indicate they were monitoring the conversation. I heard extra "dit dits" more and more often as the adventures of Brutus continued.
