Applications to Modify Licenses for AMTS
Stations WQPY965 and WQPY964
Request for Waiver of Sections 80.92(a) and
80.385(a)(2) to Allow a Private Land Mobile
Radio System on AMTS Spectrum
Adopted: July 29, 2014
Released: July 30, 2014
By the Deputy Chief, Mobility Division, Wireless Telecommunications Bureau:
Introduction. On November 8, 2012, Chesapeake Operating, Inc. (Chesapeake) filed the
above-captioned applications1 seeking to modify its geographic licenses for Automated Maritime
Telecommunications System (AMTS) Stations WQPY964 and WQPY965 by adding six fixed locations
in southwest Texas.2 Chesapeake also seeks waiver of certain Part 80 rules to allow it to operate a private
land mobile radio (PLMR) system on AMTS spectrum.3 For reasons set forth below, we grant the
applications in part but dismiss them with respect to one of the requested locations, and we grant
Chesapeake’s request for waiver.
Background. The AMTS service was established to meet the communications needs of
vessels on inland waterways,4 but the Commission’s rules now permit AMTS stations to provide service
to units on land, including PLMR service.5 In 2002, the Commission adopted a geographic area licensing
approach for AMTS stations.6

2 Specifically, Dilley, Cotulla, Tilden, Crystal City, and two locations at Carrizo Springs. The same sites are
proposed for both licenses, which differ only with respect to which AMTS frequencies they authorize.

Federal Communications Commission
In establishing rules for AMTS, the Commission considered the potential for interference to
television reception, particularly with respect to television Channels 10 and 13, because of the proximity
of AMTS frequencies to those channels.7 An applicant proposing to locate an AMTS station within 169
kilometers (105 miles) of a Channel 13 television station, or within 129 kilometers (80 miles) of a
Channel 10 television station, must submit an engineering study demonstrating the means it will use to
limit interference to television reception.8 While geographic licensees generally are authorized to place
stations anywhere within their service areas, the Commission requires individual licensing of stations at
locations for which the rules mandate submission of an engineering study demonstrating how interference
to television reception will be limited.9
Chesapeake proposes operations within 169 kilometers of Channel 13 Digital Television
(DTV) Station KVTV, Laredo, Texas (KVTV).10 Eagle Creek Broadcasting of Laredo, LLC (Eagle
Creek), the licensee of Station KVTV, filed a petition to deny the applications, arguing that Chesapeake’s
proposed operations will not afford adequate interference protection to television reception.11
Chesapeake is a producer of natural gas that focuses on discovering and developing
unconventional natural gas and oil fields onshore in the United States.12 It acquired AMTS frequencies in
nine counties in Texas,13 and seeks to use the spectrum for a communications system to provide advanced
Supervisory Control and Data Acquisition (SCADA) technologies for natural gas exploration and
production.14 Both the master stations and the remote units will operate in simplex mode on the AMTS
base and mobile frequencies.15 As a result, Chesapeake seeks a waiver of Section 80.92(a), which
requires Part 80 licensees to monitor a frequency prior to transmitting;16 and 80.385(a)(2), which divides
AMTS spectrum into coast (base) station frequencies and ship (mobile) station frequencies.17
Discussion. Licensed sites. Section 80.215(h)(3) of the Rules provides that if there are at
least one hundred residences within both the proposed AMTS station's predicted interference contour and
the television station's Grade B contour, the AMTS applicant must (1) show that its proposed site is the
only suitable location, (2) develop a plan to control any interference its operations cause within the
television contour, and (3) agree to make any necessary adjustments to affected television receivers to

eliminate such interference.18
Chesapeake asserts that these requirements do not apply here because none
of its interference contours overlaps one hundred residences in Station KVTV’s protected contour.19
Eagle Creek maintains there are more than one hundred households in the overlap area of the
proposed Cotulla station’s interference contour and KVTV’s protected contour.20 Eagle Creek notes that
Chesapeake’s engineering study departs from the OET Bulletin 6921 methodology by incorporating a
DTV cross-polarization loss factor that artificially and substantially reduces the area considered, and
understating the potential interference from Chesapeake’s proposed stations under free-space analysis.22
After reviewing the record, we conclude that there are more than one hundred households in the overlap
area of the proposed Cotulla station’s interference contour and KVTV’s protected contour.23
Consequently, we find that Chesapeake has failed to meet the requirements of Section 80.215(h)(3) with
respect to this station. In particular, Chesapeake has not presented a sufficient plan to control interference
to TV reception as required by Section 80.215(h)(3)(ii).24 In light of this conclusion, we need not address
whether Chesapeake’s filings adequately address its other obligations under Section 80.215(h)(3).
Eagle Creek’s own engineering study indicates that there are no residences in the other
overlap areas.25 It argues, however, that the 2010 U.S. Census figures relied upon by Chesapeake likely
understate the current number of households in those areas in light of recent population there, and that
18 See 47 C.F.R. § 80.215(h)(3). The Grade B contour was used to define the service area of an analog television
station. With the conversion to DTV, the Commission developed the noise limited service contour (NLSC) to
approximate the same probability of service as the analog Grade B contour. See Avista Corporation, Order, 27 FCC
Rcd 263, 266 ¶ 7 (WTB MD 2012) (Avista), recon. denied, Order on Reconsideration, 28 FCC Rcd 5258 (WTB
MD 2013), review pending. In discussing Station KVTV’s protected contour herein, we refer to its NLSC.

21 OET Bulletin No. 69, “Longley-Rice Methodology for Evaluating TV Coverage and Interference” (Feb. 6, 2004).
The procedure in OET Bulletin 69 is used to determine the predicted geographic area and population served by a TV
station. See Advanced Television Systems and Their Impact upon the Existing Television Broadcast Service,
Seventh Report and Order and Eighth Further Notice of Proposed Rule Making, MB Docket No. 87-268, 22 FCC

22 See Reply Engineering Statement at 2.
23 Commission staff verified the accuracy of the Reply Engineering Statement, undertaken with a Longley-Rice
analysis pursuant to OET Bulletin 69. Chesapeake and Eagle Creek disagree with respect to the proper desired-to-
undesired (D/U) signal ratio for predicting interference to television reception. Chesapeake used the -33 dB D/U
ratio employed in another case concerning AMTS interference to digital television reception, see Opposition at 6
(citing Avista, 27 FCC Rcd at 266 ¶ 6), while Eagle Creek believes a D/U ratio of -26 dB is appropriate because it is
the ratio specified in OET Bulletin 69 and 47 C.F.R. § 73.623(c)(2) for first-adjacent interference to a digital
television station from an upper-adjacent digital television station, see Chesapeake RF Consultants, LLC,
Engineering Statement prepared for Eagle Creek Broadcasting of Laredo, LLC, attached as an exhibit to the Petition,
at 3-4. We need not resolve this dispute here, however, because there are more than one hundred residences in the
overlap area when calculated using either a -26 dB D/U ratio or a -33 dB D/U ratio.
24 47 C.F.R. § 80.215(h)(3)(ii). Chesapeake states only that it “has the ability” to maximize the spectral distance
between its operations and Channel 13 by operating only on the 219 MHz AMTS frequencies. See Opposition at 6-7.
Even if we interpret this as a commitment to do so, this plan is inadequate for an AMTS station that is not co-located
with the potentially affected television station. See Mobex Network Services, LLC, Order, 20 FCC Rcd 17959,

Chesapeake bears the burden of establishing more current data.26 We agree with Chesapeake that it was
not obligated to undertake such an effort.27 The Rules do not require any particular means of determining
the number of households in the overlap area; using the most current U.S. Census data is a reasonable
method, and is preferable to the imprecise anecdotal evidence presented by Eagle Creek.28
Eagle Creek also argues that Chesapeake should provide information on planned remote
transmitters.29 We agree with Chesapeake that these transmitters, operating under the same power limits
and antenna heights as ship stations, do not have to be individually licensed or separately analyzed.30 The
AMTS rules do not require an analysis of ship stations’ potential for interference to television reception,
and when the Commission amended the AMTS rules to permit service to units on land, it authorized such
service to both fixed and mobile units under the same conditions.31
10. With respect to the sites other than Cotulla, therefore, we have no basis to find the
applications deficient. We accordingly will grant the applications except insofar as they request authority
to locate a new station at Cotulla. We remind Chesapeake that AMTS stations are authorized on the
condition that no harmful interference will be caused to reception of existing television stations.32 AMTS
licensees are expected to help resolve interference complaints, and must cure any impermissible
interference to television reception must cure the problem or discontinue operation of the station.33
Waiver request. Section 1.925(b)(3) of the Commission's Rules provides that we may grant
a waiver if it is shown that (a) the underlying purpose of the rule(s) would not be served or would be
frustrated by application to the instant case, and grant of the requested waiver would be in the public
interest; or (b) in light of unique or unusual circumstances, application of the rule(s) would be inequitable,
unduly burdensome, or contrary to the public interest, or the applicant has no reasonable alternative.34
As noted above, Chesapeake proposes to operate in simplex mode with base and remote
transmitters using both the base and mobile sides of the channel pair. It requests a waiver of Section

coverage areas. See Expanding the Economic and Innovation Opportunities of Spectrum Through Incentive

under the same power limitations as marine radios and their antennas are not mounted higher than those on vessels).

the Commission amended its rules to permit AMTS stations to provide private correspondence service to units on
land, it stated that the following factors would be considered in evaluating waiver requests: (a) whether the
applicant will provide priority to maritime communications, (b) the distance of a proposed land mobile radio
operation from the nearest navigable waterways, (c) the magnitude of divergence sought from specific Part 80
technical requirements, (d) whether alternative spectrum that could accommodate the proposed PLMR or other land
mobile radio service is unavailable or unsuitable for that purpose, and (e) whether grant of the waiver would benefit
public safety or homeland security (including support of critical infrastructure). See Flexibility Order, 22 FCC Rcd

80.385(a)(2), which provides separate AMTS coast station and ship station transmit channels.35 In the
ship transmit portion, Chesapeake will restrict the power levels to those permitted for ship stations in
Section 80.215(h)(5)(i), thereby providing protection against interference to maritime operations.
Additionally, remote terminals will employ directional antennas such that Chesapeake’s operations will
not exceed the permitted signal strength at the border of the licensed geographic area.36 Because the
proposed configuration will not affect other licensees any more than compliant base and mobile stations,
we conclude that a waiver of this requirement is warranted.37
Chesapeake also requests a waiver of Section 80.92(a), which requires monitoring prior to
transmitting, because its system is configured to transmit only broadband data, and cannot support voice
communications.38 Chesapeake argues that monitoring the frequencies prior to transmitting is
incompatible with the operation of a simplex SCADA system and unnecessary because Chesapeake is
authorized for an exclusive geographic area license.39 We agree that a waiver of this requirement is
warranted under the circumstances presented.40 Chesapeake’s proposed use of the AMTS frequencies
does not jeopardize the maritime community’s ability to meet its operational, safety and security
communications needs, and permitting the use of the subject frequencies for PLMR operations will
promote the efficient use of AMTS spectrum and serve the public interest by supporting critical energy
exploration operations. We therefore waive this requirement.
Accordingly, IT IS ORDERED, pursuant to Sections 4(i) and 303(i) of the
Communications Act of 1934, as amended, 47 U.S.C. §§ 154(i), 303(i), and Section 1.925 of the
Commission's Rules, 47 C.F.R. § 1.925, that the Request for Waiver filed by Chesapeake Operating, Inc.
on November 8, 2012, IS GRANTED; and applications FCC File Nos. 0005484248 and 0005484271
SHALL BE GRANTED IN PART with respect to locations 1, 2, 4, 5, 6, and DISMISSED IN PART with
respect to location 3, consistent with this Order and the Commission’s Rules.
This action is taken under delegated authority pursuant to Sections 0.131 and 0.331 of the
Commission's Rules, 47 C.F.R. §§ 0.131, 0.331.
