Fall Solar Interference Returns
It’s that time of year (and we don’t mean Pledge Drive Lite). Each spring and fall our geosynchronous NPR satellite passes directly between KNAU and the sun. The orbital mechanics are a lot like the solar eclipse last month.

But as the sun passes into the line-of-sight of our satellite dish antenna, we temporarily lose our satellite connections:  one with NPR and another one linking to our transmitters which are also satellite-delivered in Prescott, Page and Grand Canyon.
The outages will happen at about 11:16 from October 5th to the 8th.  At their peak, these interruptions will start with deteriorating signal with a complete dropout lasting as long as 90 seconds. But many listeners won’t hear a problem at all.

Here’s a link to a site that explains it pretty well.
