From our friend Rafael Diniz:
"We don't know the schedule yet. Just 100W... People from Ministry and EBC assembled something like the Sottens trial equipment (Spark + linear amps), but the antenna will be a very good one."
"...the trial will be at 9750 KHz on Friday, After 14:00 UTC (12h in Brasilia)" [That is 16 January 2015]
UPDATE: not much from my location...
