With a call in the entry window, a move of more than 2 kHz on the same band puts the call on the bandmap where it was heard and wipes the boxes, as N1MM does. The spot goes to the other stations as ADDSPOT and to the Spots broadcast, never to the cluster. ADDSPOT from other stations is added to the bandmap.
