Strategic Technical Planning for Broadcasters


Skywaves formally objects to the new FCC FM translator interference rule
Over 850 applications were filed in the January window for AM stations to file applications for new FM translators.
Effective date April 10, 2017.
2016 window translators may be moved again.
LED tower lights can save money on power, but many are invisible to the Night Vision Goggles used by the Coast Guard, civilian operators like Medevac helicopters, and the military.
Save some birds, save a little money - but only if your tower is at least 450' tall.
In its Rural Radio proceeding (MB Docket 09-52), the FCC placed new limitations on community changes. A recent release clarifies some of this.
Want to change your station's community in order to do an upgrade? You must read this.
Many FM broadcasters may benefit from the ongoing downgrades of under-height Class C stations.
With the digital conversion of broadcast television, many stations in the NCE reserved band below 92 MHz may upgrade their facilities.

The FCC now allows two-step minor-change upgrades and relocations.

New Opportunities for Non-Commercial / Educational (NCE) Station Upgrades

September 5, 2010
With the digital conversion of broadcast television, many stations in the NCE reserved band below 92 MHz may upgrade their facilities.

Most NCE stations that transmit vertical-only, or with reduced horizontal power, may now increase their horizontal power to match their vertical power.  Many NCE stations may increase both vertical and horizontal power.

Vertical polarization is optimum for reception in vehicles, and horizontal polarization is optimum for reception in buildings such as dormitories, office buildings, and apartments. If you have reduced or zero horizontal power, you may be able to improve your signal significantly.

Before the conversion to entirely digital television transmission and the demise of analog full-power TV broadcasting, NCE stations were required to protect full-power channel 6 television stations from interference. This often resulted in very limited power, or in the use of antenna systems that produced mostly - or only - vertical transmission.

While digital full-power TV stations still must be protected, nearly all the analog TV 6 stations moved to UHF channels, and are no longer subject to interference from NCE interference. For this reason, you may be transmitting with reduced power to protect a channel 6 signal that no longer exists!

One of the more confusing aspects of the digital transition is that in order to protect their trademarks and historic market positioning, many of these stations are still being identified as "Channel 6" even though they actually transmit on different channels.
