This is just one rule in Part 97 that some Division Directors do not KNOW.. Sad state we live in today.. How many more do they not understand yet want to recommend change. When they do not realize what they are changing... If it were not so embarrassing it would be laughable. All we can hope for now is they try to KNOW Part 97 before they make further mistakes. Or assumptions. This notice below from 1995 explains its purpose and how it was conceived. It does not say ONLY Automatically Controlled Digital Station, can work in the Automatically Controlled Digital Sub Bands.. It just says all unattended to Unattended contacts must be in these subbands. all other responding to interrogation can be on any frequency in the HF Ham Bands Digital Segments.. And any digital mode can also be in the ACDSs. Its not an exclusive Band Segment for any mode or group.. No one owns a freq and we share our resources.. Wake up ARRL.. PLEASE.. 73 Jerry N9LYA NOTICE ********************************************************* NOTICE ********************************************************* This document was originally prepared in Word Perfect.

INTRODUCTION 1. On June 13, 1994, we adopted a Notice of Proposed Rule Making (Notice) in the above-captioned proceeding. In the Notice, we proposed 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. In this Report and Order, we adopt the proposed rules. II. DISCUSSION 2. In response to the Notice, we received nineteen comments and one reply comment. The comments ranged from recommending that automatic control not be authorized under any condition to recommending that automatic control be authorized unconditionally. They confirmed generally that the amateur service 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. The comments, however, generally agree that the conditions proposed will provide the necessary degree of protection against such interference. They indicated, moreover, that the desired communications can be carried out under the conditions proposed. 3. Except for temporary authority we issued to permit a feasibility study directed by The American Radio Relay League, Inc. (ARRL), automatic control has not been authorized on the HF bands. Heretofore we have considered immediate action by the station control operator as necessary to avoid causing interference to the communications of other amateur stations transmitting on an HF band. A station transmitting on an HF band usually demands greater attention by its control operator than does a station transmitting on Very-High Frequency (VHF) and higher frequency bands because HF radio wave propagation is long range and changes often. The comments, however, indicated that such operation is practical on the HF bands when the automatically controlled station is simply responding to interrogation by a station having the control operator at its control point or when the station is transmitting on a channel located within a small subband designated for that purpose. 4. The ARRL supports the proposal. It states that absent consensus in the comments, we should take the compromise approach reflected in the rules as proposed. It contends that authorization of automatic control will result in greater flexibility in experimentation and development of digital communications as well as facilitate adaption of existing digital technologies to practical use. In another comment that strongly supported automatic control, however, Colby states that establishing and maintaining communications on a shared HF channel is no different than it is on a shared VHF channel, and opposes any conditions on automatically controlled amateur stations beyond those now required in the VHF bands. The ARRL argues that additional conditions proposed are necessary because any automatically controlled station transmitting in a crowded shared HF band involves a substantially increased risk of interference. Other comments also express concern with an increased risk of interference. Further, they oppose the establishment of subbands as a solution to the interference concern because subbands would significantly reduce the available spectrum for stations transmitting other emission types. 5. Automatic control of stations transmitting digital emission types enables amateur operators to utilize high-speed computer-based message technology for the rapid and accurate relaying of messages and data. For this reason, we conclude that there has been demonstrated a need for stations in the amateur service to transmit on the HF bands under automatic control. Such operation will result in greater flexibility in experimentation and development of digital communications. 6. We do recognize the concerns of those who oppose the proposal on the basis of potential interference, and in response to these concerns we are limiting 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, we are designating subbands to which transmissions between two automatically controlled stations are confined. These subbands are a small portion of the spectrum otherwise available for digital emission types. We also are confident in the ability of the amateur service community to respond, as it has in the past, to the challenge of minimizing interference with novel technical and operational approaches to the use of shared frequency bands. 7. Requiring automatically controlled stations to transmit only in the designated subbands when communicating with another automatically controlled station, furthermore, will not reduce the HF spectrum available for other emission types. The bandwidth of the transmissions of an automatically controlled station will occupy no more than 500 Hz, and the subbands represent only 3.8 percent of the HF spectrum authorized to the amateur service. Other than Morse telegraphy, only digital emission types are currently authorized for the specified subbands. Nothing in the rules that we are adopting prohibits other stations from continuing to share these subbands. III. CONCLUSION 8. In summary, we are amending the amateur service rules to authorize automatic control of amateur stations. To lessen the possibility of inadvertent interference, 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. We believe these rule changes will allow the amateur service community to contribute to communication technology and to advance its communication and technical skills consistent with Section 97.1 of the Commission's Rules, 47 C.F.R. 97.1. We see this action as fundamental to our commitment to provide maximum flexibility to the amateur service community. Therefore, we will amend the amateur service rules as set forth in the attached Appendix. IV. ORDERING CLAUSES 9.
