6913 kHz
Steady carrier since 2306z, doesn't seem to be a heterodyne from some other station. Nothing audible. In the clear because WYFR's Spanish language programming sked on 6915 was temporarily off air.
2320z: WYFR returned on 6915, wiped out 6913 altho' carrier still audible on 6913.
2110z / 4:10 PM CDT Carrier, no modulation, less than S1, on 6915 kHz started at/prior to 2110z ... this is prior to the 'big show' firing up on same frequency in a little while ... IOW, engineering looks to be performing some on-the-air testing, carrier only.
Now seeing some *wild* cyclical signal fluctuations up to S4 ... just repeated ...
2130z still present ... S3 signal peaks, carrier only.
