1742 UTC: Heard tones (selcall of some sort?) or DTMF touch tone on 6925 USB. The AM signal on 6925 is gone now as well (at least at on my local RX setup and on the K2SDR WebSDR).
1749 UTC: I stand corrected. There's something on the SDR waterfall on 6925 AM still. Hard to tell if its music or the two-way comms on 6925 as the band seems to be getting noisier.
1751 UTC: An AM signal pops out of the noise on the waterfall. Still fading up and down but I can hear music down in the noise in AM mode.
1754 UTC: Fading is getting worse. Signal disappears, comes back up nice and loud for a second and then its gone again. Band is noisy, noise level is around S5.
1755 UTC: More business comms heard on 6925 USB.
1800 UTC: Data bursts and other sounds on USB. Then more voice traffic. Still a very faint carrier on 6925.0 kHz.
1812 UTC: AM carrier comes back out of nowhere! More swelling dramatic music for a few moments then back to just a carrier. Very rapid fading/QSB. Signal was nice and strong for a bit and then dropped back down to just above the noise level. Weak two-way voice traffic back on 6925 USB, fading in and out with the AM signal.
Tuned back in at 2000 UTC. AM carrier still there on the WebSDR waterfall. Nothing heard on the local RX setup.
