Keep in mind there is no regulatory baud rate limit for digital voice or digital SSTV. Any emission designators with a second symbol of 1 or 2, and a third symbol of E or C are considered Phone/Image respectively. There are no baud limits for these emissions. The baud limits are for emission designators with a second symbol of 1 or 2, and a third symbol of B or D.
PR Docket No 88-139 released in 1988 is the foundation of our current part 97 rules. In this docket the FCC states: "We wish to recognize and encourage the experimental nature of the amateur service. It is appropriate to avoid, to the extent possible, placing in the rules detailed regulations and specifications for the configuration and operation of various amateur communications systems. Such regulations and specifications would reduce the flexibility that is a hallmark of a service free to branch out and follow an infinite number of paths.... This enables amateur operators to utilize their individual stations in creating and pioneering communication systems that are limited only by their personal interests, imagination and technical skills." Then under advancing the radio art the FCC states: "It is our intent that amateur operators in the United States be allowed to experiment with the full range of modulation types." They go on to state: " The principal use of emission designators in regulations for the amateur service is to relegate the transmission of certain inharmonious emission types to different segments of the frequency bands." The only restriction that we have with the current regulations is that in the RTTY/Data subbands we cannot mix data and image emissions; and in the Phone/Image subbands we cannot mix data with Image and phone. I think this is the biggest flaw in the current regulations and why I submitted my petition which is referenced in PR Docket 04-140 as the "Miller Petition". It tries to remedy the flaw in the current regulations restricting mixing of data and image emissions. When I use the term data, I am using it with reference to emissions designators. It is interesting that you will not find a definition of data anywhere in Title 47 of the CFR. You will find what emission designators define data, but now verbal definition. 73, Mark N5RFX Need a Digital mode QSO?
