Umm, WHDH did not move to Needham until 1947 (though the CP was probably
granted prior to Word War II and conceivably could predate NARBA--March 29,
1941). To my knowledge, though, what is now WEEI never operated from that
site on any frequency other than 850. According to the AM database, the
towers are 207 degrees high and 120 degrees apart. The precise 120-degree
spacing certainly suggests that the array was never designed for another
frequency. Although 207 degrees is quite high, with a better than normal
ground system, which I believe WEEI has, I don't think it is excessive. By
no stretch of the imagination could 207 dgrees be claimed to be 100' too
short, however.
