We looked round the small museum in Droitwich this morning. I found the salt aspect of this disappointing - the Lion Salt Works museum on the Trent and Mersey Canal, with its large scale reconstruction of a working salt works, is much better.
But what Droitwich is really famous for - for me, anyway - is the BBC transmitting station which for many years radiated on 1500m long wave. (These days it's actually 1515m as the frequency was changed to 198kHz so that all AM broadcast transmissions were on frequencies a whole multiple of 9kHz (this happened in 1978, I believe)).
Down a corridor by the salty exhibits (mostly skulls and skeletons, by the way) is the more interesting part of the museum. An area dedicated to the old days of the BBC, when the BBC ran its own transmitters, studios and production. This being Droitwich, the exhibits were mainly connected with the transmitting station. On the left below is an early version of the main control desk.
