Both operate at the same daytime power (5,000 watts), but WTIK's pattern is much stronger north of Durham than WRJD, which sends the lion's share of its power to the southeast. At night, WTIK is licensed for 1,000 watts but their engineer once said they run at only 500 watts, while WRJD runs only 290 watts at night and literally drops off the face of the earth about Northern High School when traveling north on US 501 due to the tight null to the northwest in their pattern.
Update on WRJD...what little bit I listened between Christmas festivities, the station seemed to continue in normal automation mode after the Sunday ministry programs concluded at noon (one was live and mentioned the station's imminent demise). Around 10:15 this evening, I checked in again to faintly hear a farewell message from GM Linda Greenwood, whose company, Unwind Productions, has operated the station for the last five years (unfortunately I could barely pick out any details from the static since I was in northern Durham). As of just before midnight, the transmitter was broadcasting dead air, as it still is as I post this.
I can't say I'm surprised that Rejoice 1410 failed, but it is bittersweet to see the end of an era for a station whose legacy was so integral in the history of radio in this region.
