First buzzered / gonged off the stage and then vindicated, all
before I could doublecheck my facts and respond. The wonders of the
internet. But since I was checking this in the middle of the night, I will
say: I have a list from a NRC meeting that shows XEX (100 kW, it turns out)
as the only I-A [or I-B] / Class A station on our continent on 730. I have
an old Broadcasting yearbook that lists 730 as a Mexican clear channel,
while other channels are listed as Mexican & Canadian clear. And the FCC
database lists CKAC as "Class 2," (now Class B).
CKAC's great nighttime (actually it starts to come in very well
before sunset) coverage certainly could make you think it is a Class A.
And it's because the channel is still quite clear, although the U.S. now
has flea power stations on it (WACE, Chicopee, Massachusetts, for example).
Also, it's DA-1, so perhaps the Northeast gets a beam of much more than 50
kW. But the old NARBA limits and Mexico's reluctance to allow exceptions
kept that channel clear at night in the United States.
BTW, the only 250 kW Mexican station I found in glancing through
the list, not entirely thoroughly, was the Mexico City station on 900, the
calls of which are escaping me at the moment.
