CT Yankee,
You are right about WXYT 1270, it is not clear channel, it is class B 50kw day and night with directional antenna.
Actually, there are no more Class 1-A clear channel stations (only station allowed on a given frequency at night). The history is somewhat convoluted but they went away some time ago. Today's clear channel stations are class A and share their nighttime frequency with limited protection from a number of other stations.
Interesting to look at an old 1963 publication showing WMAQ 670 Chicago, WLW 700 Cincinnati, WGN 720 Chicago, and WOAI San Antonio (all 50kw stations) as the only stations on their frequency day and night. However, by then, many of the other clear channels had perhaps two widely geographically separated 50kw stations sharing a frequency at night.
