From the archives of RTÉ (Ireland's national broadcaster): This show was recorded in 1962 about the establishment of the signal towers for rural radio and television broadcast.

In it an engineer named John O'Keefe described how they chose the sites for masts in an unusual way. Rather than the usual process using contour maps, they made a 3D model of Ireland and placed lights on hills to see how signal would travel.

A linked question to #mastodaoine : I know this is a long shot, but in the documentary that I linked in the last toot, I'd love to know if anyone knew/knew about the engineer John O'Keefe, pictured here.

This was in 1962, and O'Keefe must be in their 50s at the youngest, so over 100 now. More likely there might be a death notice, a living relative, or someone that worked with them. Would be grateful for any help.

This is the beginning stages of a new art project on the five regional transmitters in Ireland.

I'm already hooked on the amazing consequences of the banal publication from the European Broadcasting Conference of 1952 (Stockholm), and how frequencies were allocated to different countries.

The steel imported from Norway, electronics from Britain, and regulations decided in Sweden already spread this so far. A single object like a signal tower can have complex social and material relationships.
