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.

Upgrade opportunities

September 22, 2010
Many FM broadcasters may benefit from the ongoing downgrades of under-height Class C stations.

Many years ago, the FCC recognized that a very large number of Class C stations had built facilities that barely exceeded the maximum for Class C1 (100 kW and 299m HAAT). 

As an example, 60 Class C stations today have HAAT of less than 310m, and each is currently protected as if its HAAT were 600m. The actual protected contours of these stations fall at 73km or less, but they are protected as if their protected contours extend to 92km!

In order to mitigate this problem, the FCC established Class C0, with a HAAT of 450m.  This reduced the protection to 83km, a very significant improvement. They established a procedure under which an applicant could request a downgrade of a conflicting Class C station to Class C0. In many cases, the incumbent Class C has agreed to the downgrade, given the alternative of applying for and building a facility with a HAAT of at least 450m.

As of this writing, there are 251 licensed Class C0 stations, and many more Class C stations are likely candidates.

If your facility currently uses reduced power or a directional antenna in order to protect a Class C station, you may be able to upgrade to full power, non-directional antenna, and upgrade your Class or eliminate your 73.215 status.  At present, 1,800 stations are classified as short spaced, many to Class C facilities.

Please contact Skywaves for a full evaulation of your station's upgrade capabilities.
