OM repeating "Hola! Que tal?" ("Hey what's up?") over and over. Very strong S9+ signal
Can only hear one station, so its possibly somebody is just testing/tuning up (which would explain the rather random frequency choice, although he is right in the middle between 6900 kHz and 6925 kHz.)
At 2327 or so, he moved up to 6915.5 kHz USB and continued testing.
