It would be difficult to pause without notice with DV due to the latency issue. This is one of the reasons that I do not expect DV to ever become all that popular on HF. And if there are attempts to improve the sensitivity and robustness, the latency would have to become even more noticeable since I doubt that there is any chance to have wider bandwidth modes such as you have on VHF and up with over 6 kHz wide signals.
Latency can be acceptable for text modes, but much more problematic with voice. DV does not really lend itself to fast break in technique such as used on net operation or quick round tables where individuals make rapid back and forth comments. Without some major breakthrough, which at this time seems unlikely to contravene the laws of physics, HF DV seems destined as a niche player, similar to the way AM is still used. I have been getting a bit concerned with some of the strong statements being made lately by some of the more overzealous proponents of digital. Based upon the Dayton Hamvention Digital Forum presentations, it is getting a bit much, with claims that digital technology is destined to replace most analog technology. Because of the many downsides to digital technology, this is most unlikely on HF. It may eventually become more popular on VHF and higher frequencies due to the allowance of wider bandwidth modes. There are good uses for digital and there are good uses for analog and one is not always the best choice over the other. 73, Rick, KV9U kd4e wrote: > Couldn't DV include a automated brief pause every > 1 or 2 min to check for doubling? > > It would be so brief as to be almost indiscernible > to the op and would trigger a warning of some sort > only if doubling (defined by certain parameters) > were detected. > > WDYT? > >
