Well tracked down Sideband…. It could be ironic that the site for the legal Radio Caroline transmitter is Orfordness….
At the time when RNI was being jammed I was living in Rayleigh, Essex, which as the crow flies is roughly 5 miles from Canewdon and I remember it playing havoc with reception in the area. Still remember listening to RNI and the jamming using my Radionic set!
Below is a link to the site about a land based pirate radio station and how they tracked down the transmitter.

I frequented the same radio spares shop The Radio Constructors Centre in Westcliff mentioned in the site
