Solar Interference: March 1-5

Feb 27, 2017

Every spring and fall, all satellite receivers (including JPR’s) experience brief periods of high level background noise due to the alignment of the sun, the satellite and the satellite receive antenna.  The digital audio channels used in the public radio system are more resistant to solar interference than the older analog audio channels, however, the disadvantage is that when they do fail, they fail completely and without warning. The only sound is a brief chirp.

This year, outages are expected to occur from March 1st through March 5th at around 10:38am. Luckily, due to the timing, our broadcast days will be relatively unaffected.  The only disruption we expect to be noticeable will be during our Saturday morning broadcast of the Met Opera's Werther. 

These outages are a minor side-effect of using satellite technology to distribute live radio programming, and unfortunately are unavoidable.
