One of the things I wanted to do on my return to Cornwall this year (it seems you can’t be banned from the county for dipping a Cornish pasty in a bottle of sauvignon so I was able to go back) was to revisit the Telegraph Museum at Porthcurno and talk with the volunteers who maintain the old telegraphic equipment. Many are ex-telegraph engineers themselves so know a thing or a hundred about telegraphs.
Imagine: it’s a bit before 1870 and, being a wealthy Victorian, you decide to connect the new-fangled telegraph-whatchamacallit to the rest of the world (or The Empire as it was known then). You find a nice quiet cove and haul the first cable, going all the way to Portugal, onto the sand. Well, OK, YOU don’t personally because you have people to do that sort of thing.
And it all worked very well, with Morse code messages being sent back and forth from America, India and, of course, Portugal. Problem was that the signal, having crawled along thousands of miles of underwater cable, was feeling a bit washed out by the time it reached anywhere, so relay stations were built along the routes, which is why Britain and other Western European countries became very interested in those tiny Caribbean islands – it wasn’t just they fancied sunny holidays at the Empire’s expense. Messages would arrive, tired and a bit worse for wear, then be retyped (re-keyed in Morse parlance) onto the next bit of cable and so on. Lots of people were needed which was fine because there were a lot of people who fancied a holiday at the expense of the Empire.
Of course, if there was one thing Victorians were in love with, it was the idea of automation. If there were two things, then the other would have been sunny holidays at the expense… oh, you know the score. So, the idea of REGENERATION was born, long before Doctor Who made it a handy way of changing the actor at the end of a series.
The issue was, as with great comedy, that of timing. How could you synchronise and also understand an exhausted signal from thousand of miles away? It needed some kind of clock and rejuvenating in some way.
And that involved a motor. And another blog post…
