OFF AIR: R. Nac'l Amazonias 11780khz

11780 was off Thu. Aug 30, on Fri, then it's been off since.

I have a contact in the radio engineering department at Empresa Brasil de Comunicação and asked what was up.

Theres a fault with a piece of equipment, though I'm not quite clear on what it is, as despite my years in radio and understanding of tech, im not too familiar with the equipment. My contact says: "We have a problem with the logic tx, it won't protect the transmitter and allow the transmitter on at high power. The logic tx is very old"
 
The EBC shortwave transmitters are from the 1970s and have had a plethora of problems in recent years. No idea what happened to their DRM plans with new units.
 
Look like theyre back on.. they came back on sometime today
