Faint Spanish voices heard near the bottom edge of the 40 meter ham band. Very minor data QRM nearby. I have logged 6985 kHz USB several times, but I don't show 6983 kHz anywhere in the logs so this may be a new one for me. I know that means very little, since these guys literally pick a frequency and go but hey...
SIO 111
EDIT: At 2113 UTC, a very strong data burst on 6981 kHz USB (possibly ALE sounding?) obliterated the two-way pirate bootleg freebander freebanding QSO going on on 6983 USB.
