Faded in at around 1745, maybe a few minutes later. Stronger signal locally and on U.S. East Coast SDRs, including the W3HFU and N1NTE SDRs. Very dramatic fading at points. Signal actually dropped out completely for 10-15 seconds around 1753 UTC.
Frequency: 26110 kHz 26,110 kHz 26.11 MHz 26.110 MHz 26.1100 MHz FM STL cue transmitter Part 74
Also checked the carrier transmitter on 25.950 MHz, it is much weaker than usual, also very dramatic fading.
KOVR's STL signal went off the air (very clearly so - several seconds of unmodulated FM carrier, then the transmitter was switched off) at 1755 UTC.
At 1757 UTC, the carrier came back on...then off again at 1757 for 4-5 seconds, then back on with audio again (still at 1757 UTC). On the air with studio audio at 1758 UTC.
