Search the WSJT-X log ALL.TXT, which is updated live, for certain states or grid squaress.

For a ham radio digital mode called FT8, sometimes I want to watch for a person in a certain state or at certain grid coordinates. The software WSJT-X highlights "CQ" calls based on grids and countries, but it doesn't highlight the messages of stations talking to each other in the midst of a contact.
