As usual, USCG weather (station callsign NMN) on 6501 kHz USB booming in, but I noticed another, weaker station nearby on 6507 USB. Turns out its Australian HF maritime weather transmitter VMC. WLO was also booming in on 6519 kHz USB with computer-generated voice ID for WLO and relay station KLB (both read phonetically). WLO stated "standing by for calls" and frequency went silent, followed by USCG NMN signing off.
VMC out of Australia still coming in nicely on 6507 kHz USB at 1137 UTC.
