Tonight around 0730utc I heard the same signal on 3900. At the same time it is also on 3550 and 7050. I also heard it several times a year ago. It is typically on for an hour or thereabouts. I have no idea what the source is. Checking on SDRs in California, Utah, New York and Alaska, I heard the 7050 signal on all of them, with the Utah SDR having the strongest signal.
