SUBJECT: Proposed FCC rule changes
The Federal Communications Commission (FCC) has announced their proposed
rule making relative to the use and operations of "repeaters" in the
Amateur Radio Service. This is one of the most important issues to come
before the Commission thus far regarding changes in the present rules.
The proposed changes, if adopted, will render present repeater operations
somewhat illegal. There are many applications for repeaters in emergency
communications, specifically RACES, that necessitate our involvement.
The State, on behalf of interested local governments, will prepare comments
to be forwarded to the Commission. These comments, which are to state
our requirements and position, will undoubtedly influence the final outcome.
I am enclosing a copy of the FCC's Proposed Rule Making Docket 18803 for
your review and consideration. You are urged to coordinate with your
Communications and /or RACES Radio Officer and prepare your comments. Should
you desire to file separately with the FCC, rather than jointly with the
State, please forward a copy of your comments to me.
Your comments should reach this office no later than May 1, 1970 in order
that we can coordinate your comments and file our joint proposal by May 15,
1970.
AMATEUR RADIO SERVICE
Licensing and Operation of Repeater Stations
In the matter of amendment of Part 97 of the Commission's rules concerning
the licensing and operation of repeater stations in the Amateur Radio Service
Docket No. 18803; RM -388, RM -1087, RM -1209.
1. The Commission has under consideration a joint petition filed by
James W. Kyle, Jr., Robert B. Cooper, Jr., and Russell L. Miller (Kyle)
(RM -388), and petitions filed by the State of Texas, Division of Defense
and Disaster Relief (Texas)(RM- 1087), and the Buffalo Amateur Radio Repeater
Association (BARRA) (RM- 1209), for the rule making in the above- entitled
matter. All petitioners proposed that the Commission amend its rules to
specifically provide for the operation of amateur stations which would auto-
matically repeat the transmissions of other amateur stations. Comments
supporting the Kyle petition were filed by Arizona Amateur Radio Society.
Comments supporting the BARRA petition were filed by Electronic Industries
Association; Tulsa Repeater Organizations, Inc., and Rocky Mountain VHF
Society, Inc.
2. A repeater station, as the term is used herein, is an amateur station
which receives and automatically retransmits radio signals primarily for the
purpose of extending the communication range of mobile units. Repeater stations
are particularly useful on VHF bands where reliable communication is generally
over relatively short distances. Although the present rules do not specifically
refer to repeater stations, under policies that have developed, amateur stations
licensed to persons holding a Technician or higher class licenses have been per-
mitted to operate as repeater stations consistent with the rule permitting remote
control and other rules applicable to all amateur stations. The present rules
require, among other things, that the licensee be present at the transmitter
orat an authorized control point when the station is in operation; that remote
control points must be at fixed locations designated on the station license;
that all emissions of the remote transmitter must be monitored by the licensee;
and that the operation of the station must be under the positive supervisory
control of the licensee, i.e., it must be possible for him to suspend the radia-
tion of the transmitter regardless of any control signals transmitted by another
user station for the purpose of gaining access to the repeater. The station
licensee is also required to comply with the logging and station identification
requirements applicable to the usual amateur station. In response to the peti-
tioners requests, the Commission proposes to amend its rules to specifically
provide for the operation of amateur repeaters.
3. Since the operator of each station using a repeater is required to
maintain a log of his transmissions, and the duplication of the information
in the repeater log would serve no useful purpose, it is proposed that the
repeater log include only the time and date of the periods the repeater is
available for service, and entries indicating the technical and operational
condition of the repeater. It is also proposed to amend the present identi-
fication rule to permit automatic identification of repeaters by telegraphy
at intervals not to exceed three minutes.

4. With respect to the operator and monitoring requirements, BARRA
proposed that an amateur repeater station be permitted to operate without
an operator in attendance at the transmitter or at an authorized control
point. In support of its proposal, BARRA stated that since a repeater
does not originate communications, the responsibility for communication
content should be placed solely on the licensee of the station using the
repeater, because he is responsible for the propriety and content of any
signals transmitted by his station. The licensee of the repeater would
then be responsible only for the technical operation of his station.
Section 310(b) of the Communications Act requires, in effect, that the
licensee of a station maintain supervision and control of both the tech-
nical and operational performance of his station. Accordingly, it is
proposed herein to continue to require the licensee of a repeater station
to be in attendance at the transmitter or at an authorized fixed control
point, and to monitor all transmissions of the station.
5. Because of the shared use of amateur frequencies, equipment
limitations which may preclude monitoring the repeater input frequency,
and the inability of repeater users to observe activity on the repeater
output frequency throughout the area served by the repeater, consideration
must be given to the interference potential of repeaters to amateurs
operating on the same and adjacent frequencies. The proposals set forth
below should tend to minimize interference between stations, but not unduly
inhibit the growth of a useful repeater system.
6. The propagation characteristics of the amateur bands below 50
Mc /s are such that mobile stations and stations at fixed locations can
communicate over short, medium, and long distances on those frequencies
without recourse to repeaters. In view of this, there is no apparent
need for retransmission on frequencies below 50 Mc /s or for multihop
repeater systems on frequencies above 50 Mc /s. Accordingly, it is pro-
posed to permit the operation of repeaters only on frequencies above
50 Mc /s and limit the automatic relaying of communications to a single
retransmission. It is also proposed to adopt the recommendations of
Kyle and BARRA that a repeater be so designed and installed that it will
normally be activated only by means of a coded signal or such other means
as will effectively exclude transmissions by stations not desiring to work
through the repeater, thus minimizing unnecessary transmissions and the
possible resulting interference. The required coded signal may consist
of a single audio tone so that the repeater can be easily "whistled on."
7. To further minimize interference, and in the absence of any apparent
need, the simultaneous retransmission by a repeater in two or more bands
of the same received signal will not be permitted, nor will cross -band
operation, that is receiving in one band and transmitting in another, be
permitted. It is also proposed to specify frequency subbands in the 50,
144, 220, and 450 MHz bands, for repeater input and output. It is believed
that by restricting repeater operation to specific portions of the amateur
bands a more useful and uniform system will result, and interference to the
operation of stations not transmitting through repeaters will be minimized.
-3-
The proposed frequency subbands are tentative in that they may be adjusted
within the band if comments received indicate a need for such adjustment.
8. It is proposed to limit the power input to repeaters to 600
watts. This is consistent with the maximum power permitted in the land
mobile services and is believed sufficient to provide reliable communica—
tions within the range of mobile units. Also, the rule sections relating
to operator requirements and station identification have been revised to
codify present Commission requirements.
9. The specific rule changes proposed herein are set forth below.
Authority for these proposed amendments is contained in sections 4(i) and
303 of the Communications Act of 1934, as amended.
10. Pursuant to applicable procedures set forth in Sec. 1.415 of the
Commission's rules, interested persons may file comments on or before May
15, 1970, and reply comments on or before June 1, 1970. In accordance
with the provisions of Sec. 1.419(b) of the Commission's rules, an original
and 14 copies of all statements, briefs, and comments filed shall be fur-
nished the Commission. All relevant and timely comments and reply comments
will be considered by the Commission before final action is taken. The
Commission may also take into account other relevant information before it,
in addition to specific comments invited by this notice.
Adopted: February 26, 1970.
Released: March 2, 1970.
