Impressive.....but still hard to top WHOM (94.9), Mt.Washington, NH....48kw ERP, HAAT ~4700' (Mt. summit is 6288' ASL....)
Studios are in Portland, ME. -- about 50 miles east --- they were using 8' dishes for their STL (back in the good ol' analog days.....!)...
They have listeners in NY, VT, NH, ME and Quebec, Canada.....
Up until about 15 years ago, they shared transmitter space with WMTW-TV (Channel 8)....both were powered by a huge diesel generator on the summit....
The generator and TV are gone....commercial power is fed "to the top" now......
