REPORT AND ORDER 
Proceeding Terminated 


Adopted: November 19, 1984 Released: November 21, 1984 
Introduction 


l. This proceeding was initiated by a Notice of Proposed Rule 
Making adopted February 3, 1984, and published in the Federal Register at 49 
F.R. 3221. The Notice was in response to a petition filed by George E. 
Molnar, Jr., supported by eight other parties of interest, seeking amendments 
that would modify the procedures under which AM, FM, and TV broadcast stations 
operate their transmitting systems by remote control. 


Comments 


2. The Notice proposed and invited comments on rule amendments which, if 
adopted, would make substantive changes in both the equipment requirements and 
operating procedures applicable to broadcast remote control operation. Eleven 
formal and two informal comments were filed. One reply comment was filed. A 
list of the parties filing pleadings is contained in Appendix A. All parties 
except Mr. Alvin C. Saltzman favored the deregulatory objective of the 
proposed rule amendments, Many, however, objected to one or more of the 
specific provisions of the proposed rules. 


3. Nearly all respondents stated that the primary difficulty with remote 
control operation under the present rules is the fail-safe requirement, 
Currently, remote control operation of the transmitter must immediately cease 
if the control circuit is interrupted. Stations apparently experience 
occasional loss of service due to short term disruptions in control circuits. 


4, While many comments were made suggesting adjustments or 
clarifications of certain specific provisions in the proposed rules, two 
significant new issues were raised in the comments. The National Association 
of Broadcasters (NAB) stated that the current remote control rules are 
unnecessarily complex and suggested that revised rules need only contain two 
regulatory provisions: 1) permit the ùe of remote control for broadcast 
facilities, and 2) restrict required control functions to those mandated by 
law, national security, or public safety. The Association of Federal 
Communications Consulting Engineers (AFCCE) suggested that termination of 
operation is not necessary if an AM station fails to switch operating modes 
and does not cause interference. A nondirectional station that operates at 


its authorized reduced nighttime power during daytime hours is an example of 
this type of situation. 


Discussion 


5. The present remote control rules were derived from the transmitter 
duty operator rules which are, in turn, based upon Section 318 of the 
Communications Act of 1934, as amended. That statute requires that all 
broadcast stations be operated under the control of a licensed operator. The 
Act does not specify the duty location of the operator nor the necessary 
degree of control of either the transmitter or other station technical 
functions. However, the Commission's rules now require a licensed operator to 
be on duty at the transmitter site or at a control point shown on the station 
license. Also, each remote control point used must: 1) have equipment 
permitting the operator to determine the station's operating power and other 
transmitter conditions, 2) permit certain adjustments, 3) be inaccessible to 
unauthorized persons, and 4) not permit the transmitter to turn on 
inadvertently without operator supervision. The existing rules also require 
stations to have an operator in attendance at the actual transmitter site 
whenever the control or metering circuits between the transmitter and remote 
control location are disrupted or do not function correctly. 


6. The present rules were written at a time when the available broadcast 
technology required that the duty operator make frequent observations and 
transmitter adjustments. Also, the Commission considered it essential to be 
able to immediately contact the duty operator during all hours of operation. 
Revision of the remote control rules must address the current validity of 
these concepts. 


7. The Commission shares the concern of the licensees in that short-term 
losses of control or telemetry should not be cause for immediate termination 
of operation. Accordingly, the new rules will permit continued operation 
following a loss of transmitter control, pending repair of the control 
circuits, as long as the station continues to operate properly. Loss of 
telemetry, on the other hand, means that the transmitter parameters cannot be 
monitored remotely. Therefore, the amended rules will require termination of 
use of remote control within three hours after detection of the telemetry 
failure. Although CBS recommended six hours, the majority of the commenters 
on this subject concurred with the proposed three hour period. 


8. The considerable variation in the several classes of broadcast 
stations leads to difficulty in writing technical rules that would be 
practical for every licensee. Indeed, a review of the comments clearly 
indicates that the simplest approach is the best in the interest of both 
broadcasters and the public. Remote control technology has far outstripped 
the simplistic “on-off, raise-lower, read meter” concept upon which the 
original remote control rules were based, and the rules should reflect those 
advances, as well as permit use of future developments. 


Conclusions 


9. The Communications Act requires that a licensed operator have F 
supervisory control over the station's transmitter during all periods of 
operation. However, that operator need only be able to terminate the 
station's operation should it be the source of harmful interference or be 
operating inconsistently with law or treaty. Meters, alarms or automatic 
controls could be used to facilitate this supervisory control. Therefore, the 
amended rules are devoid of "how to" or methodology provisions. Rather, the 
rules place responsibility on each licensee to assure compliance with the 
station authorization. The existing rules already provide tolerances for 
those operating parameters considered necessary for correct broadcast station 
operation. 


10. The Commission continues to believe that it must be able to contact 
stations during operation. Therefore, the use of remote control at sites - 
other than at the main studio or transmitter address must be identified to the 
Commission if the station cannot be contacted during operation at either the 
studio or transmitter locations. 


ll. We agree with AFCCE's comments that a station need not terminate 
operation in cases where an inability to change operating modes will not cause 
impermissible interference. The amended rules will permit continued operation 
in a mode having lesser radiation at all bearings and elevations than that 
authorized following a temporary failure in mode switching functions. 


12. The Commission has consistently held in previous proceedings that 
licensees should have flexibility in operating their stations. 1/ 
Consequently, we have chosen an approach that meets the basic requirements of 
the Communications Act while allowing licensees maximum flexibility in meeting 
those requirements. In general, licensees may operate their stations by 
remote control using any method that assures that: 1) an operator is on duty, 
2) the transmitting system operates properly, and 3) the Commission can 
contact station personnel during hours of operation. 


13. Accordingly, IT IS ORDERED That Part 73 of the Commission's rules IS 
AMENDED as set forth in the attached Appendix B effective December 1, 1984. 


14, It is FURTHER ORDERED That the Secretary shall cause a copy of this 
Report and Order to be furnished to the Small Business Administration. 


15. It is FURTHER ORDERED That this proceeding is TERMINATED. 
16. Regulatory Flexibility Analysis. 
I. Need and purpose of the rule. 
The amended rules remove separate and diverse rules for AM, FM, educational 
1/ Refer to the deregulation of the licensing requirements for radio 
operators, (See Report and Order in Docket 20817 at 46 F.R. 35450) and 


deletion of the technical log keeping requirements (See Report and Order in | 
Docket 82-536, at 48 F.R. 28457). 


The amended rules remove separate and diverse rules for AM, FM, educational 
FM, and TV broadcast stations, and replace the removed rules with a common 
rule applicable to all classes of broadcast stations. Licensees will have 
complete freedom to choose remote control equipment that meets their 
individual needs. 


II. Legal basis. 


The Rule amendments made by this Report and Order are authorized 
under Sections 303(£) and 303(r) of the Communications Act of 1934, as 
amended, in order that stations operate in a manner consistent with the terms 
of their authorizations and without causing harmful interference to other 
radio communications services. 


III. Description, potential impact, and number of small entities 
affected. 


This action would simplify the technical equipment and operating 
requirements for all AM, FM, and TV broadcast stations that operate their 
transmitting facilities by remote control. Nearly 6,000 stations will be 
affected. Further, approximately twenty mamfacturers of broadcast 
transmitting equipment will be able to market remote control devices using 
advanced technology that the present rules constrain or prohibit. 


IV. Recording, record keeping, and other compliance requirements. 


The amended rules impose no record keeping requirements, nor do they 
require any additional application or notification procedures. 


V. Federal rules which overlap, duplicate, or conflict with this 
tule. 


None. 

VI. Significant alternatives not adopted. 

The rules hereby amended incorporate all significant suggestions 
submitted in response to the Notice of Proposed Rule Making and resolve all 


issues of concern.

10. In 47 CFR, new Section 73.1400 is added to read as follows: 
§73.1400 Remote control authorizations. 


(a) An AM, FM, or TV station transmission system may be operated by 
remote control using the procedures described in §73.1410. 


(b) No authorization from the FCC is required to operate the 
transmission system of an AM station operating with a nondirectional antenna, 
FM station, or TV station by remote control. Authority to operate an AM 
station using a directional antenna system by remote control is obtained using 
the following procedures: 


(1) An application for a construction permit to erect a new 
directional antenna or make modifications in an existing directional antenna, 
subject to the sampling system requirements of §73.68, may request remote 
control authorization on the permit application FCC Form 301 (FCC Form 340 for 
noncommerical educational stations). 


(2) A licensee or permittee having a sampling system in compliance 


with the provisions of §73.68(a) must request remote control authorization on 
FCC Form 301-A, and submit information showing that the directional antenna 
sampling system has been constructed according to the specifications of 
§73.68(a). 


(3) A licensee or permittee of a station not having an approved 
directional sampling system in compliance with the provisions of §73.68(a) 
must request remote control authorization on FCC Form 301-A, and submit 
information showing that the directional antenna is in proper adjustment and 
further showing the stability of the antenna system during the l-year period 
specified in Section II of Form 301-A. 


(c) Whenever a remote control point is established at a location other 
than at the main studio or transmitter, notification of that remote location 
must be sent to the FCC in Washington, D.C., within 3 days of initial use of 
that point. This notification is not required if responsible station 
personnel may be contacted at the transmitter or studio site during hours of 
operation when the remote control operator is elsewhere. 


ll. In 47 CFR, new Section 73.1410 is added to read as follows: 


§73.1410 Remote control operation. 


(a) Broadcast stations operated by remote control must provide at remote 


control points sufficient control and operating parameter monitoring 
capability to allow technical operation in compliance with the Rules 
applicable to that station and the terms of the station authorization. AM 
stations that are required to change modes of operation during the broadcast 
day must provide sufficient redundency to assure that such mode changes 
actually occur. 


(b) The remote control system must be designed, installed, and protected 


so that the transmitter can be activated or controlled only by licensed 
transmitter operators authorized by the licensee. 


(c) The remote control and monitoring equipment must be calibrated and 
tested as often as necessary to ensure proper operation. 


(d) The remote control system must be designed so that malfunctions in 
the circuits between the control point and transmitter will not cause the 
transmitter to be inadvertently activated or to change operating modes or 
output power. 


(e) Whenever a malfunction causes loss of accurate indications of the 
transmitter operating parameters, use of remote control must be discontinued 
within 3 hours after the malfunction is first detected. If the station is 
found to be operating beyond the terms of the station authorization and such 
malfunction cannot be corrected by remote control, station operation must be 
immediately terminated. 


(f) AM stations may use amplitude or phase modulation of the carrier 
wave for remote control telemetry and alarm purposes. FM stations may use 
aural subcarriers and TV stations may use either aural subcarriers or signals 


within the vertical blanking interval for telemetry and alarm purposes. Tse Āu 
of such remote control signals mist be in accordance with the technical 
standards for the particular class of station, 


12. 47 CFR 73.51 is amended by changing the reference to rule °73.57" in 
subparagraph (d)(5) to read "73.1410." 


13. 47 CFR 73.68 is amended by removing subparagraph (b)(4) and redesignating 
subparagraph (b)(5) as (b) (4). 


14., 47 CFR 73.1225 is amended by removing sub-subparagraph (c)(1)(iv)(A) and 
redesignating sub-subparagraphs (B) through (D) as (A) through (C). 


15. 47 CFR 73.1560 is amended by revising the headnote, redesignating 
existing paragraph (a) as subparagraph (a)(1), and adding new subparagraph. 
(a)(2) to read as follows: 


§ 73.1560 Operating power and mode tolerances. 
(a) AM stations. 
(1) *** 


(2) Whenever the transmitter of an AM station cannot be placed into 
the specified operating mode at the time required, transmissions of the 
station must be immediately terminated., However, if the radiated field at any 
bearing or elevation does not exceed that permitted for that time of day, 
operation in the mode with the lesser radiated field may continue under the 
notification procedures of paragraph (d) of this section. 


* * * * * 


16. 74 CFR 73.1570 is amended by removing the words "§73.67(b) or" from 
subparagraph (b)(1) (ii). 


17. 74 CFR 1690 is amended by revising the words "See §73.3548" in 
subparagraph (d)(2) to read “See §73.1400.”
