Are we even looking at the same elephant? With digital there is NO errors, errors are simply discarded. If one freq is not suitable for xmission of the packet(s), another is computer selected and attempted. Spread spectrum makes digital rock solid, no noise, no errors ... these systems operating in GHz processing speed range makes the whole thing transparent ... and all that before I even mention data compaction ...

However, all we need to do is do it, problem solved. Considering how delicate a digital signal is -- and how little the room for error is (either you have perfect reception or you have nothing), do you think that's a good idea for emergency comms? At least with analog, you may get some static, but you can still pick up what the person is saying on the other end. The implementation of HD or DRM on short wave may leave you with the impression that digital is more "delicate" than analog but it is really about the same as far as robustness is concerned. Digital or analog can be more robust by using more bandwidth for example. -- Telamon Ventura, California |
