Correct. When AM stations move, they have to follow what's called the
"ratchet" rule, which requires that they demonstrate a 10% reduction in
the total amount of interference they cause to other stations on the
dial. So most of KRKO's new power goes out to sea, while the signal
toward other co- and adjacent-channel stations will be unchanged or even
a little lower.
