0433 UTC I have a solid carrier here with maybe some imaginary threshold audio...music?

Yeah. I noticed it on K3FEF SDR and went to check K1VL in Vermont and heard nothing. I assumed that it was just some weird internal spur but if you are hearing it too, maybe it's true.

0441 - Gone.

From a recording.
The carrier appeared at 0404, about 15 db above the background noise.  There were excursions to about 20 dB over.  I heard no audio until 0437 when there was some instrumental music (an oboe?).  The carrier was gone at 0439.

The Elad suggested that the frequency was 6924.95. 

In my corner of suburbia, with my ears, 15 dB over the noise in AM doesn't work.  I need at least 25, but prefer 30.

I had this on the SDR recording, very weak.

Curiously, there was also a weak carrier on 6974.9 kHz from 0255 until 0404 UTC, when it switched to 6925 (this log).  Which makes me suspect both are Nowhere Radio.
