Well worth a visit.

http://www.radarmuseum.co.uk/

Just spent a very interesting 3-4 hours there. Lots to see, and almost
certain to be of interest to many posters in this forum. Some very
knowledgeable volunteers there as well.

Cleared up one little thing that had always been beyond my limited
electronics theory from many years ago, pulse-echo time compared to speed
of rotation of the aerial.

Several rooms had that smell of bakelite and varnish used on old equipment,
R1154/R1155 anyone......
