Radio tower question: WLLH?
Fri Apr 4 21:45:40 EDT 2008
What was the big old vertical radiator that used to stand on a hill on the
west side of 495 between Lawrence and Lowell? It was at Exit 39, I think
(Route 133). It was replaced sometime back in the '90s, if memory serves,
but was there for years and years before that. It was a very sizeable
tower. Was it associated with WLLH, WCCM or what?
Also: Assuming that WLLH stands for "Lowell, Lawrence, Haverhill" (?), did
the station ever actually have a physical presence in Haverhill?
