Yesterday, Paulo sent this information:
"It came to my attention that our brazilian friends on Fleetsat and UFO frequencies got a nasty surprise today, from their federal police and Brazil´s comunications authority. According to the news, 39 persons got busted, one was arrested and large amounts of equipement seized. All of them are licenced amateur radio operators whose operating location was determined by the US Dept of Defense, in cooperation with brazilian federal police and other US agencies. Besides all of these equipment seizures, the authorities have identified the manufacturers of some of the hardware used, one of them actually was arrested.
