Upon a trip home this past week to celebrate my father’s 75th birthday; I noticed very severe interference to 55KRC’s nighttime signal just northwest of Cincy over in Indiana. KRC’s signal there is usually very good [it actually improves with their change to the night pattern despite the power reduction to 1kw due to the reduced daytime limit toward 560 WIND Chicago]. Every night this past week, they began receiving co-channel interference from one strong signal around 9:15PM EDT... By 9:30PM, the offending signal manages to nearly equal KRC’s to the point that the two carriers actually “beat”.
I first thought it to be KTRS St. Louis since they had been on a non-directional STA at about 1kw due to a fallen tower last summer. KRC had received some intrusion from this arrangement, but I hadn’t noticed it this past spring and wondered if KTRS could still be on that STA a full year after the freak weather incident that took out one of their towers.
Tonight [Friday evening], the interference is so severe that a clear ID copy [and baseball coverage] was very easy to hear. It is WDUN Gainesville, FL. Interesting that they managed to recently jump to 10kw ND day, but maintain a highly-directional 2.5kw signal with the only lobe aimed near due-south [at 190-degrees]. There is nearly no energy allowed to radiate toward Cincinnati. How could such a parameter [properly followed] allow for interference this severe? On the 10kw ND day facility, maybe? Possibly, the CCU techs should investigate... Hey KRC folks – you’re un-listenable in Franklin County, Indiana near Brookville Lake!
