Eric, Interesting and neat. I should have expected you were already on top of this. :-)
I just went back to the K3 and played with it a bit. Just by listening, the monitor delay seems to be the same whether I have VOX enabled or not. This is just the normal acceptable delay I have come to expect in the K3's monitor. The Smooth Voice Controller had a nominal 85mSec delay (QST article April 1992 pg. 42) and, if I recall correctly, seemed much more noticeable than what I am hearing in the K3. Eric, can you comment on the amount of delay used for the K3 VOXing? (Saves me setting up for a measurement.) Does the monitor come before that delay? Am I hearing, in the monitor, what is being transmitted (relative to the PTT-voice timing and first syllable cut-off)?

You can talk normally without that 'Ahh' at the beginning of sentences to avoid loss of info ;-) 73, Eric elecraft.com On 2/21/2013 8:07 AM, Wright, Robert wrote: > I used to have a box from A&A Engineering called a Smooth Voice Controller. > It was a VOXer with a short audio delay line (bucket brigade IC) to allow the > PTT to get to the radio before your first syllable.
