Thanks to Lindsay, VK3GX, for bringing this wonderful BBC program to my attention. The team shows the development of radio and makes various transmitters and receivers. They build a coherer and demonstrate it for example.
Keep watching after the end credits for some comments from the presenter.
Incidentally, the cartoon depiction of Marconi's home are quite accurate. I visited it some years ago.
I really loved this video and am so glad they re-mastered it. The build of the spark-coherer set was simply brilliant, as was the demo on the Bounmouth pier. This led us into a close look at the coherer as a possible detector. Maybe OK for the Bournmouth pier to land, but not so sure if it would span the Atlantic. Marconi may have had a better detector for that contact! 73 Bill N2CQR
