Interesting reading, but I find it hard to believe there were no activations between 1955 and 2004! Certainly there must have been some other activity from Marion or Prince Edward during that time period.
These will be filled in today. I usually can find these pretty easily - for Marion Island its been a little bit trickier - which is kind of strange.
Lots of details come in after I post these blogs - from hams who worked the entity or who have artifacts worth adding to the blog. Some of the back stories I get from readers end up "making" the article.
