Back on Monday June 14th, something went wrong with the feed from the VOA Portuguese studios in Washington, DC to the Botswana shortwave transmitter. The first half hour of the broadcast on 12080kHz went fine but something went wrong at news time. I caught the problem as it happened while Dxing and recording it from Alaska.

Then for 25 minutes, they played a 40 second VOA jingle music bed over and over and over.... and over till the VOA Portuguese feed suddenly reappeared.
