What Happened to My Station?
It’s been good season for tropospheric ducting along the New England shore. You might not be familiar with the term “tropospheric ducting,” but you just might have experienced it and not known why.
We’re all familiar with the way that AM signals bounce at night and come down far from their point of origin. Anyone who has listened to the big 50,000 Watt clear channel AMs knows the thrill of hearing a distant AM on a regular radio. I was once surprised to hear WBZ from Boston while in a traffic jam one night in Atlanta, Georgia. An AM station’s “skywave” component reflects off the ionosphere as it cools down at night and the usually transparent-to-AM layer turns reflective and the AM signal comes back to earth far from it’s transmitter. Frequency and tower height influence the degree of skywave along with seasonal differences and weather conditions.
Citing low publicity surrounding an order adopted by the FCC in March 2016 and lack of input from LPFM stations, REC Networks has filed a motion for either a blanket waiver or extension of time for LPFMs.
Currently the FCC has established that all EAS participants must report some EAS details to their State Emergency Communications Committees by Nov. 6. The information includes:
A separate reporting requirement due by Nov. 13, known as Form Three, should detail the results of the most recent National EAS Test.
