How does someone submit an update for the nationwide database? "Nationwide" does not appear as an option under the "State" drop-down menu. I am wanting to submit tone data for the Red Cross (146.2 Hz).
From the posts I have seen reference to relief efforts for Hurricane Harvey, 146.2 Hz was reported. Also, about ten days ago I heard a Red Cross convoy coming through Arkansas on its way to Florida, I think, and their PL was 146.2 Hz on 47.420 MHz. So, I venture to say that that is their tone for nationwide assignments.
