Many thanks to SWLing Post contributor, Dave Porter, who writes:
This is a recent posting of a trip out to the Knock John Fort and also of a new book about life on a sister fort, Roughs Tower.
Report – – Knock John Sea Fort – May 2018 | Noteworthy Report
The fort is still dry inside. This was the home of R Essex and the RCA ET4336 + T aerial. When Bates closed Essex they moved to the Roughs.
Check Amazon for the book “Holding the Fort” by Bates son [affiliate link]. It’s a hardback book and is excellent. An early Christmas present!! Plenty of pics and Sealand as well plus their TX and studio.
Fascinating! Thank you for sharing this, Dave!
Considering how expensive the physical copy seems to be maybe they should order a new printing?
I’m not 100% sure, but I think on the 40’s pinups wall picture you can spot on the top row, Hedy Lamarr. I’m sure you all aware of her frequency-hopping patent.
