In the Case of RM-10740: I respectfully submit to the commissioners that the proposals of Mr. Lonneke and Mr. Ladisky in RM-10740 not be adopted, on the following grounds: 1. The bandwidth standards they propose are technically flawed, in that they do not adequately define the bandwidth limits. Simply stating "2.8 Khz" is meaningless without reference to at least two amplitude levels on the bandwidth bell curve and a defined standard test modulating signal. To adopt a rule without these exact standards is to invite a flood of complaints based on subjective guesses. 2. The petitioners have not presented documentation concerning how they concluded that the signals about which they complain were overly broad, other than their subjective senses. For instance- many HF receivers are subject to distortion in the front-end at high signal levels which creates spurious products within the front-end of the receiver. Improper use and/or adjustment of noise blanking circuits can create spurious products within the receiver's IF circuitry. The petitioner's have presented no technical standards whatever on which to base their complaint, so we cannot know if the above conditions are or are not the case. 3. The petitioners have not demonstrated that the practice of which they complain is either currently wide-spread or increasing. In fact, the practice is limited to a vanishingly small number of licensees. Moreover, the history of Amateur Radio strongly suggests that, over a reasonable period of time, peer pressure and a waning of interest in this "enhanced SSB" mode will correct the problem. The petitioners are asking the FCC to go to the effort and expense of rule making over a minor, self-limiting problem. 4. Adoption of this rule would go against the FCC's stated objective of streamlining and reducing government rules and restrictions. There are already rules within Part 97 (97.307, 97.101) that stipulate transmissions shall not use more bandwidth than is required for the type of emission used. While "enhanced SSB" is an experimentation- a defined goal of the Amateur service- it is not a new type of emission and is, therefore already in violation of Part 97. New rule making is not needed. If licensees wish to experiment with the variation of SSB signals known as "enhanced SSB," they can do so at VHF frequencies where there are less restrictions, or apply for a Part 5 Experimental license. 5. This rule making could lead to the requirement of type-acceptance of transmitters in the Amateur service, or even channalization. Such a requirement would utterly destroy one of the stated purposes of the Amateur service: to encourage experimentation and provide a pool of people acquainted with communications technology. Adoption of type-acceptance rules would effectively end the Amateur service, leaving only "plug-n-play" operators without justification for the spectrum allotted them. It would also require the FCC to draft an entire new class of rules and standards to implement the type-acceptance, with the resulting expense in both budgetary and human resources. Current Part 97 rules adequately address the issues in the petitioner's complaint. 6. Adoption of this rule would seriously impact the legitimate users of A3H modulation. These users are already restricted to effectively reduced radiated power. They voluntarily restrict themselves to small and agreed-upon frequency "windows." They are generally well behaved and tolerant of the interference they receive from SSB transmissions. Moreover, this group of legitimate users work to preserve the history and development of amateur, broadcast and military radio. They also provide a pool of technical expertise useful to the A3H broadcast industry. Notwithstanding the emotional protests of a few who dislike A3H, there is no credible evidence that these A3H transmissions have caused significant hardship on any other licensee. Implementation of this arbitrary bandwidth standard could effectively ban these legitimate licensees from the air. Thank you for your time and your consideration of these comments.

Right on.
99% of the SSB activity that is the focus of all this is on 14.180 or thereabouts. It is hardly widespread, and is never likely to become so. It may be annoying to some, but the number is small, and the supposed increased bandwidth used by most practitioners is small. And as you point out a bandwidth limit, with only a cutoff frequency specified, is utterly meaningless. This petition is the kind of pointlessness that drives FCC people crazy for no good reason, undermining the hobby's bargaining position when really serious issues come along. g David Stinson wrote: 11 July 2003 In the Case of RM-10740: I respectfully submit to the commissioners that the proposals of Mr. Lonneke and Mr. Ladisky in RM-10740 not be adopted, on the following grounds: 1.
