Jerry has some good points and questions. The ICOM ad has to be the worst ad I have ever seen in an amateur radio magazine. What were they thinking? They need to produce a quality ad that draws people in rather than push them away. They need to explain why their stuff is the stuff to get. They did not do that.
Thus far ICOM has been the only company promoting the D-Star open standard that was developed in Japan. You need competition to insure that this equipment is going to be available for the long term and get the prices down to amateur pricing. But in order to have anyone buy such products, they need to be able to do something that can not be done now, and for the most part, must be able to at least meet current technology with all other attributes of the product with existing products. I am not sure that D-Star can do this. The speed is not very fast compared to WiFi and with WiMax type equipment available, I wonder if its time has already come and gone due to the rapid advance of technology? The 2 meter and 440 D-Star equipment has very slow digital capability so it does not seem to be able to improve what we already have. The 1.2 gig equipment can not compete against 2 meter and 440 equipment for range based upon published tests. Also, I understand that the audio quality is "digital" sounding and not quite as good as conventional analog. The repeaters and controller equipment are out of sight for cost and don't really do a lot more than we can already do with IRLP and Echolink using conventional equipment for nearly no cost at all. One of the methods that I use to roughly gauge the popularity of various modes/equipment is to observe the number of reviews on eham. The WIRES-II system appears moribund since it tries to do something already done with existing systems. D-Star has all 5 ratings but only three reviews and the last review was 1 and 1/2 YEARS ago! That pretty much tells you how popular this system ... isn't. For new technologies to succeed in the market place, they have to have clear advantages over existing systems with no down sides. As an example, when packet radio came along, it was so much better than VHF RTTY running through a regenerative repeater that it was adopted quickly. Not to mention it was very low cost too. It had so many advantages, such as digipeating, mailboxes, etc. What are the advantages of D-Star? For those of us who like to be just back of the knee of the curve of the "bleeding edge" it does not seem to offer many benefits that we don't already have and it has some inferior characteristics compared to existing technologies. I can not imagine ever using it in our area for mobile voice since it would not work anywhere near as well as what we have now. By the way, considering all the new technician class hams, why is there such a minimal use of repeaters? Clearly, the new entrants can not be using their license and this greatly concerns me. Also, considering the huge numbers of VHF only hams, and the proliferation of rigs with multimode/VHF/UHF capabilities, how can it be that there is almost no activities on these frequencies? 73, Rick, KV9U Jerry W wrote: > In QST March 2006, pages 129 to 136 Icom is promoting their new > radios.
