Holy ship! That's a lot of watercraft! Amateur Radio isn't my kind of thing but, I took a quick look at the list out of curiosity. I see ships from all over Europe on the list, and the LS Huron too.
I looked at the Huron Lightship Museum online not too long ago, and really should visit some day. It's only a 65 minute drive east on I-69 to Lake Huron where it's docked. It was the last operating lightship on the Great Lakes, and was dedicated as a National Historic Landmark in 1990. Admission would only cost me $7.00, and the Thomas Edison Depot Museum, a 2 minute drive away, would be another $7. I could entertain myself all day for $14 + the price of gas. If that's not enough to occupy my time, the Fort Gratiot Light Station is another 4 minute drive, and the Carnegie Center, with the Kammer Cabin living history exhibit, is only a 3 minute drive the other side of the Huron Lightship Museum. That would be a good starting point and could take all day. If it did, I could see all the rest another day. The two furthest of the four points are an 8 minute drive apart. The $7 admission to each place is still cheap entertainment compared to amusement parks, which is just about the only other place I (used to) buy tickets to.
I'm going over the whole Museum Ships list to see if I get any more ideas for a day trip or vacation.
