[Elecraft] K3 VOX question

[Paul Fletcher]

I don't think there is a need for the delay to be incorporated in the
monitor audio - it should be possible to either put the delay after the take
off for the monitor or have a separate path though the DSP for the VOX
detection. Understand and agree with your findings though, I have an
SDR-1000 and the latency in the monitor makes it impossible to use with
headphones.

One rig that uses a fixed audio delay effectively to avoid the "missing 
first syllable" problem is the Kenwood TS-870. But an unintended 
consequence of the design is that the transmit audio monitor is, at 
least for some users, difficult or impossible to listen to. I prefer to 
monitor my audio to be able to quickly detect problems, but find I have 
to turn off the monitor on an 870.

If an audio delay is used in the K3, I suggest that it should be 
possible to adjust or at least disable it as a  configuration option.
