To all of the concerned and loyal listeners of WDJO: This is what Mr. Dave Dybas, the Chief Engineer for WYLL 1160-AM has to say about this thread after I shared it with him via email:
Artie,
Our research department provided me with a copy of the WDJO night IFRSS
(interference free root sum squared)pattern for WDJO. This is the pattern,
overlaid on a map, showing the area within which WDJO should NOT receive any
interference from any stations at night.
The IFRSS signal contour for WDJO is a 24 mv/m contour, which means any area
of lesser signal strength can, by FCC rules, receive interference from other
co-channel stations.
The WDJO IFRSS night contour encompasses the town of Florence, Erlanger,
Union, Lakeside Park, and touches upon Independence, Villa Hills and
Burlington. Any towns outside of that area can, by FCC rules, receive
interference from co-channel stations.
The WDJO night IFRSS contour does not cover Cincinatti and is significantly
far from Cincinatti. So anyone in Cincinatti, Covington, Bellvue, Wilder,
Highland Hts, Taylor Mill, Covedale, Walton, Chevoit, and some other towns,
will hear other co-channel stations in the background of WDJO.
You have my permission to post this information, if you like, so others can
better understand the situation.
Take Care,
Dave Dybas
