These are extremely appropriate examples. A big thing to pick up here is that SSB was a "standard" and everyone could design to it. If they had a better idea and cheaper manufacturing they could compete.
One of the things never addressed with digital is the "standards" issue. We spent millions of dollars in the telecom industry testing competing T carrier systems to insure they were compatible. Even though the specs had been issued for years, you always had some innovator that added diagnostics or signaling enhancements that caused problems. Even if they worked in a system, they screwed up the administrative and test software. How do hams address the fact that once a digital 'standard' is issued it will be very hard to change? The ARRL totally ignored this in their proposal. What do you do when Icom, Yaesu, and Kenwood all begin to issue slightly different incompatible implementations to differeniate their products? Who decides what 'standard'? Ultimately, if you want stagnation, go with a hardware box that can't be upgraded cheaply and easily and that costs a substantial amount. Computers and sound cards can do both but at the expense of very limited bandwidths. None of this addresses the issue the ARRL expressed when they said in their proposal "(b) We are in the early stages of a dramatic shift in Amateur operating patterns, especially in the High Frequency (HF) bands. It is impossible to determine now where this shift may lead." If they can't determine where this shift may lead, WHY such MASSIVE changes now? That's like someone who is lost saying lets take the next turn maybe it will get us to the right place. Chances are it won't! If an increased baud rate limit is what drove the proposal, why wasn't a simple increase, perhaps to 600 baud, properly analyzed and submitted? As far as DV today, even the ARRL review of the AOR showed it would not meet all the technical advantages of SSB, primarily S/N ratio, besides costing an arm and a leg. As above, my main problem is the buying it now and having it become obsolete in the near future. Just isn't in the cards. I don't advocate stifling experimentation and development and I don't see how that is a problem with todays regulations. But don't come in and say I have something new, don't know if the marketplace will buy it, but lets change regulations anyway. Jim WA0LYK --- In digitalradio@yahoogroups.com, "Dr. Howard S.
