After the truckers disappeared from 27525 AM, then 27505 AM, I tuned up to the international 11 meter freeband calling frequency, 27555 USB (27.555 MHz USB, 27.555 USB, Triple 5, T5, "The Triple" and about a dozen other names).
Hearing a station from Sao Paulo Brazil working another (unheard) station on 27.555 USB starting around 1833 or 1834 UTC. Station IDed as being in Brazil but is speaking excellent Spanish. Mention of Spain (not sure if he's talking to somebody in Spain right now).
Nothing heard after 1836 UTC. Possibly QSYed even though I didn't hear any request to change frequencies.
