Weak carrier here, much stronger on the OH SDR. No obvious audio.

1505 - mostly S8 here, no audio so far
1511 - some weak tones, carrier S7
1515 - carrier off after a complex tone sequence (could have been ROS mode)

Hearing what sound like test tones at 1510-1511 UTC.

Utility two-tone signal on 6925 USB (I would say "dial frequency" for the ute signal is 6925.5 kHz or 6926 kHz) but either way its right in the middle of the upper side of 6925 kHz AM.

Carrier disappeared at 1515 UTC.
