SDR recording catch:

0417 sign on with what sounded like a 50s or 60s song.  The rest of the music seemed to be from the same time period, but nothing was strong enough to ID.
0502 I think it went QRT. Difficult to tell, as it was very weak near the end.

I heard something here on May 1st at 2350 UTC-0000+ UTC May 2nd just above the noise floor with hints of music here and there, but too weak to ID the tunes. Mentioned this in the IRC chat but nobody else was hearing it. Thought it might have been a harmonic or mixing product, but found nothing on 3420 KHZ. Interesting....
