A few years back I got the scoop from Frank, K3SQP on his working career and was directed to that great web site you attached Steve. Lots of historical stuff and some really neat gear. Looks like the BA scope was bolted right to the side of the large transmitter!
Along the lines of Maritime stations, KHP out on the West Coast was a big one. Some may find interesting this link to their website. They do send out an email type newsletter from time to time when a special event occurs.
