FEDERAL COMMUNICATIONS COMMISSION
47 CFR Part 97
[PR Docket No. 94-59; FCC 95-163]
HF Digital Communications in the Amateur Service
AGENCY: Federal Communications Commission.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This action amends the rules for the amateur service to
authorize automatic control of stations transmitting digital emission
types on the High Frequency (HF) amateur service bands. This amendment
was necessary because, except for temporary authority the Commission
issued to permit a feasibility study, automatic control has not been
authorized on the HF bands. The intended effect of the final rule is to
authorize automatic control of amateur stations transmitting digital
emissions subject to two conditions: The automatically controlled
station either must be connected to another station that is under
manual control, or the automatically controlled station must transmit
only within a subband designated for communications between
automatically controlled stations.
EFFECTIVE DATE: July 1, 1995.

Summary of Report and Order
1. The rules for the amateur service have been amended to authorize
automatic control of stations transmitting digital emission types on
the High Frequency (HF) amateur service bands, subject to two
conditions for such operation. The automatically controlled station
must either be connected to another station that is under manual
control, or the automatically controlled station must transmit within a
subband designated for this purpose.
2. The amateur service community stated that it generally has a
need for stations to transmit digital emission types on the HF bands
while under automatic control. The comments also established that there
is concern that such transmissions could cause interference to other
communications. We are amending the rules, therefore, to permit
stations in the amateur service to transmit a digital emission on the
HF bands under automatic control. Such operation will result in greater
flexibility in experimentation and development of digital
communications. The Commission recognized the concerns of those who
oppose the proposal on the basis of potential interference, and in
response to these concerns it limited when automatic control can be
employed. First, the control operator of the station that is connected
to the automatically controlled station must prevent the automatically
controlled station from causing interference. Second, the Commission
designated subbands to which transmissions between two automatically
controlled stations must be confined.
3. The rules are set forth at the end of this document.
4. The rules contained herein have been analyzed with respect to
the Paperwork Reduction Act of 1980, 44 U.S.C. 3501 et seq., and found
to contain no new or modified form, information collection and/or
record keeping, labeling, disclosure, or record retention requirements
and will not increase or decrease burden hours imposed on the public.
5. This Report and Order is issued under the authority of sections
4(i), and 303(r) of the Communications Act of 1934, as amended, 47
U.S.C. 154(i) and 303(r).

Rule Changes
Part 97 of chapter I of Title 47 of the Code of Federal Regulations
is amended as follows:
PART 97--AMATEUR RADIO SERVICE
1. The authority citation for part 97 continues to read as follows:
Authority: 48 Stat. 1066, 1082, as amended; 47 U.S.C. 154, 303.
Interpret or apply 48 Stat. 1064-1068, 1081-1105, as amended; 47
U.S.C. 151-155, 301-609, unless otherwise noted.
2. Section 97.109 is amended by revising paragraphs (d) and (e) to
read as follows:
Sec. 97.109 Station control.
* * * * *
(d) When a station is being automatically controlled, the control
operator need not be at the control point. Only stations specifically
designated elsewhere in this part may be automatically controlled.
Automatic control must cease upon notification by an EIC that the
station is transmitting improperly or causing harmful interference to
other stations. Automatic control must not be resumed without prior
approval of the EIC.
(e) No station may be automatically controlled while transmitting
third party communications, except a station transmitting a RTTY or
data emission. All messages that are retransmitted must originate at a
station that is being locally or remotely controlled.
3. A new Sec. 97.221 is added to subpart C to read as follows:
Sec. 97.221 Automatically controlled digital station.
(a) This rule section does not apply to an auxiliary station, a
beacon station, a repeater station, an earth station, a space station,
or a space telecommand station.
(b) A station may be automatically controlled while transmitting a
RTTY or data emission on the 6 m or shorter wavelength bands, and on
the 28.120-28.189 MHz, 24.925-24.930 MHz, 21.090-21.100 MHz, 18.105-
18.110 MHz, 14.0950-14.0995 MHz, 14.1005-14.112 MHz, 10.140-10.150 MHz,
7.100-7.105 MHz, or 3.620-3.635 MHz segments.
(c) A station may be automatically controlled while transmitting a
RTTY or data emission on any other frequency authorized for such
emission types provided that:
(1) The station is responding to interrogation by a station under
local or remote control; and
(2) No transmission from the automatically controlled station
occupies a bandwidth of more than 500 Hz.
