In looking at the file I load into my scanner for D-Day Ohio I see I have Marine Channels 8 & 71 listed (among others). I think I've heard some landing craft comms on Marine Channel 8 in prior years. Some FRES channels are used during the various battles/skirmishes too.
I also have 123.475 MHz as the Air Boss frequency coordinating aircraft during the landing Saturday afternoon.
The Ohio MARCS Mobile Site has been brought in the past two years and multiple talk groups on that system have been used to coordinate the event.
The W8BHZ amateur repeater (147.390 MHz) in Conneaut is also used during the event. I think mostly to coordinate parking and shuttle buses.
(I know this is the Marine Forum, but I had to throw that other stuff in, since it pertains to the event
