I've seen this signal on for at least 45 minutes now. So far, however, I can only get the faintest hint of music from some New England-area SDRs.
2050 UTC: Signal's a bit stronger now via the Poland, New York, SDR with French-language music. Shazam says it's "J'ai perdu la tete" by Charles Aznavour at the moment.
2100 UTC: Sounds like more Charles Aznavour music, but the signal has retreated mostly to the noise level again.
