KMD9990

KMD9990 is a callsign, a CB callsign from the show: Doc Elliot

I didn't remember the name of the show or the actor, but I remembered the call.  And on a TV show was probably the only time anyone ever identified on CB - and he did it each and every time he picked up the mic :)

This video is a Spanish dub in rough shape so I didn't watch past the credits :)
