531kHz station is off air.
KVF returned at 1352utc on 531kHz as did the noise around 625kHz and 860kHz.
Clearly confirms the noise is coming from or being caused by KVF. The “noise” actually sounds like splatter as it is correlated with the modulation on 531. Oddly when the modulation on 531 is silent the unwanted energy ~625 and 860 is worse. When 531 is heavily modulated then the unwanted noise reduces.
Doesn’t look like the 531 tx has been repaired.

We’ve been advised by KVF that they are investigating this and operating on their standby transmitter today.
