Starting at 0400 UTC April 9th 2017
6 MHz marine band 6200 kHz to 6525 kHz
6 MHz aeronautical band 6525 kHz to 6765 kHz
6 MHz super fun do whatever you want pirate military government pescadore band aka "fixed and mobile" 6765 kHz to 7000 kHz
Only a couple of these in the legal HF marine bands. WLO marine broadcast at 0700 UTC 6519 kHz USB shows that the Spanish traffic on 6521 USB wasn't on a one of the channelized marine frequencies (channels), 6200 kHz, 6203 kHz....6519 kHz, 6522 kHz, 6525 kHz [3 kHz steps]. 6521 and 6524 kHz are 3 kHz away from each other but don't follow the ITU HF SSB marine channel plan. I tried listening to 6519 kHz and the Spanish language traffic on 6521 was making it impossible.
Lots of stations using the aircraft frequencies
Frequencies/remarks:
6412 kHz USB - Asian language, very busy after 0500 UTC
6521 kHz USB - Spanish - very strong signals 0655+ UTC - at 0700 UTC, WLO marine broadcast started up on 6519 kHz USB, causing severe QRM
6524 kHz USB - Spanish
6544.4 kHz LSB - Portuguese
6546 kHz USB - Portuguese, active around 0700-0720+ UTC
6556 kHz USB - Portuguese (??) - with adjacent channel QRM from strong HFDL data bursts on 6560
6564 kHz USB - Unknown language, active after 0700 UTC
6568 kHz USB - Unknown language, very difficult copy due to heavy QRM form 6569 USB
6569 kHz USB - Unknown language possibly Portuguese, QRMing traffic on 6568 USB terribly
6646 kHz USB - Spanish, active around 0710-0720 UTC
6706 kHz LSB - Spanish, active after 0440 UTC

6753 kHz LSB - Spanish, getting obliterated by data bursts and OTH Radar
6755.5 kHz USB - Spanish
6757.7 kHz USB - Spanish
6760.5 kHz USB - Spanish (very strong signals, very busy after 0425 UTC)
6766 kHz USB - Spanish, sounds like a OM and YL talking, heavy fading so difficult to tell for sure
6770 kHz USB - Portuguese, active after 6771.5 USB went quiet
6771.5 kHz USB - Spanish
6776 kHz USB - Spanish (different from group using 6776.5 USB as far as I can tell)
6776.5 kHz USB - Spanish (active after 0645 UTC)
6790 kHz USB - Portuguese (active after 0725-0730 UTC)
6794 kHz USB - Unknown language, possibly Portuguese (distorted audio - stations appear to be off-frequency from each other)
6808 kHz LSB - Unknown language
6838 kHz USB - Spanish, active after 0545-0555 UTC
6840 kHz USB - Spanish, active after 6838 went quiet

6885 kHz LSB - Spanish, active after 0440 UTC
6899 kHz LSB - Spanish, then QSYed back up to 6900 LSB
6900 kHz AM carrier - Station tuning up, then switched to 6900 LSB and said "Hola! Hola! Hola!" several times S9+30 signal!
6900 kHz LSB - Spanish
6900 kHz USB - Spanish (strong)
6907.5 kHz USB - Spanish (I think) with extremely strong QRM from data signal on 6909 USB
6910 kHz LSB - Portuguese (QRMing 6907.5 USB and getting QRM from 6909 USB)
6919 kHz LSB - Portuguese
6923 kHz USB - Spanish - active after 0645 UTC

6988 kHz USB - Spanish
6999 kHz USB - Spanish, active at 0530-0545 UTC and 0705-0710 UTC with [possibly intentional] QRM from CW on 7002 kHz.
