I asked this earlier but suppose it was lost in the early frenzy so I will pose the question again along with a couple more.
The basic question concerns digital voice modulation. There is no current standard but AOR is using an open protocol from G4GUO. Unlike SSB, digital voice will require some sort of standard unless we will be satisfied talking only to ourselves (not all bad, at least I would find someone who always agrees with me). I wonder if Elecraft could push things along by offering digital voice modulation as a built-in function on the K3? 1) Basic question: could the current K3 DSP handle DVM encode/decode processing while performing its other tasks? 2) Looking at the K3 photos, there seems to be (a lot of?) room under the hood. I wonder if Elecraft has designed the K3 (as they did with the K2) with plans to add additional functional modules to the original system? I am thinking, in this instance, of an independent DSP module that could do magic such as DVM without burdening the basic DSP. Heck, with an independent DSP you could even add cell phone capability to the K3 (might be nice to have out in the boonies). 3) Digital voice modulation question: I assume the basic bandwidth of a DVM signal is 3 khz. What happens, on receive, when you narrow the bandwidth of a DVM signal? Do you just lose fidelity or do you lose data (things like syllables or words)? I am not a big voice mode fan but I do believe that SSB is headed toward the same ditch currently occupied by AM. Maybe Elecraft can help set the direction for future voice modes.
