We had this in Rammy until the mid nineties Ed for TV/Radio. I think Dave Moll has the selector switch from my house on Bury New Road. I thought the signals came out on a 9 Meg feed [twisted pair] or have I got that wrong? The ref to a 100v line has confused me. Don't want to go off topic with this but I am relying on the "some other questions" aspect of the Thread Title to meet the regulations
