The ConHam simplex frequency of 146.580 has been in use at DEFCON since at least DC16, though probably much earlier than that. Standardizing on a single frequency made it much easier to find other hams in a backchannel way, without depending on sketchy WiFi and a crazy game of telephone - and it works just as well in Cincinnati.
