There is, further, a common urban myth of this kind at just about every
college radio station that began as a carrier-current operation and had
train tracks in plausible proximity. I even heard it about WLDB, the
predecessor to WBRS, and anyone familiar with the Brandeis campus knows
that it's quite the haul from the area where the studios would have been
to the commuter-rail tracks south of campus.
Did the myth originate from a real event at Tufts? I suppose that's
(And is it tied to the urban legend that a certain low-power AM outlet
in the Boston area achieves its unusually good signal by hooking its
ground system to the city water pipes?)
