Jefferson Elementary School
Serving Coquille at 88.5 MHz
The coordinates provided by the FCC Database incorrectly pinpoint the Coquille Valley Middle School. The translator was installed at the Jefferson Elementary School (geographic coordinates and map). This school has now been closed due to decreasing population in the Coquille School District.
Pictures were taken in February 2008.
A single antenna appears above the roofline. KSOR's signal was originally broadcast at 88.5 MHz.
The transmitting antenna is directly above the translator, which is located in the boiler room of the school.
Understandably, the Coquille School District was concerned about the possibility of harmful effects from the radiofrequency energy. We did a careful analysis of the of radiation levels, and then compared them to the governmental guidelines for non-ionizing radiation. Even with a 10-watt translator, the margin of safety was generous. The one-watt power level increased the margin of safety by a factor of ten. The Coquille School District carefully scrutinized the data before approving the installation.
Water pipes, electrical conduits, breaker panels, telephone terminal blocks, switches, control boxes for the boiler system, a refrigerator, a fly swatter – and yes, even a translator – fill the space in the small, cramped boiler room.
Translator on the Wall
The enclosure is locked in order to discourage the curious from playing with circuit boards and connectors.
The translator picked up a signal from Iron Mountain, 34 miles to the south. As was standard practice, the receiving antenna was located far enough from the transmitting antenna to prevent receiver overload.
Wall Mounting: the mast for the receiving antenna was bolted directly to the concrete-block wall.
