STA Application 1241-EX-ST-2016
Frequency Coordination Exhibit and Narrative
Austin, Texas World Endurance Championship Automobile Race Sponsored by
The Federation Internationale de L’Automobile
September 15, 2016 through September 18, 2016

         This application proposes the use of amateur radio, land mobile, broadcast
auxiliary and certain microwave bands in the Austin, Texas area for terrestrial only,
international and domestic video production operation; for voice communications and
telemetry for racing cars and communications with pit crews of the race teams; and for
two-way operational and security communications during the World Endurance
Championship automobile race events and for testing prior to the event within and
immediately surrounding the Circuit of the Americas Race Track. An engineering
analysis has shown that there should be no interference to any licensed user of any of the
subject bands whatsoever, and with the addition of some broadcast auxiliary channels for
use for international video and broadcast production purposes (and for some AFTRCC
frequencies for use for telemetry, with which coordination is pending), the frequency list
is otherwise precisely the same as that which was granted by the Commission each of the
last two years for this same event (See WH9XUY, File No. 0618-EX-ST-2014 and
WI9XXY, File No. 0864-EX-ST-2015). This is one of the two largest international
automobile racing events in the United States. Should any FCC-licensed or United States
government station report interference during the proposed operations, operation on that
channel or band will immediately cease and not resume unless and until the interference
complaint is resolved. However, during the past two years’ prior events using these same
frequencies, no interference has been reported whatsoever. There are on-site coordinators
for this event who are charged with interference avoidance and mitigation.

       The frequency ranges set forth herein are a subset of those requested for and
granted by STA to Circuit of the Americas, LLC previously for other racing events at this
venue.

        With respect to the proposed use of land mobile and Amateur Radio frequencies
for video production, voice and telemetry, the use of amateur allocations in this STA
application have been coordinated with the American Radio Relay League, Incorporated.
Land mobile channels to be utilized during the race event within the requested band
limits have been investigated using the Commission’s ULS database and monitored on-
site and found to be unoccupied. Technical coordination staff will be on site during the
race and channel monitoring and on-site frequency coordination will ensure against any
interference. Given the location of these events, it is anticipated that no interference will
be caused to any Amateur Radio, land mobile, broadcast auxiliary or other licensed
operations. Use of broadcast auxiliary channels will be coordinated in advance with the
Society of Broadcast Engineers’ local frequency coordinator for the Austin, Texas
market. Upon receipt of any complaint of interference from a licensed Amateur Radio
user, land mobile licensee or broadcast entity, or government entity (or otherwise),

                                              1


operation pursuant to this STA will cease on the channel complained about, and will not
resume unless and until the interference complaint is resolved satisfactorily to the
licensee.

         There is requested in this application the use of a 10 MHz bandwidth channel at
9405-9415 MHz for use for a weather radar system in support of the automobile race.
This frequency for an identical radar was granted to Circuit of the Americas in October of
2014 for the United States Grand Prix (See, WH9XYW, File No. 0912-EX-ST-2014) and
for this event in 2015 (See, WI9XXY, File No. 0864-EX-ST-2015).

Applicant will ensure that all conditions associated with the 2014 STA grant (File No.
0618-EX-ST-2014, WH9XUY) and the 2015 grant will be complied with, including
notching of the following channels within the requested frequency ranges as required in
2014:

a. Notch out the following +/- 8 kHz:
