I've stumbled upon this Facebook group which has some very interesting posts regarding broadcasting history and some references to the pirates:

I notice that on at least one post there is a comment from the admins that one contributor's comments have been deleted for breaching group rules. I wonder who that might be? 🤣

It's a public group, so no need to join unless you want to.
