[Elecraft] VOX question

[Paul M Dunphy]

     This is a temporary problem until I get FSK (PTT) RTTY wired up.  
In order to get a shot at the ZL9 on RTTY, I set up my K3 to use AFSK 
and am using two stereo cables and VOX.  That works fine.

     It has introduced a side effect I discovered this AM.  ON SSB, if I 
key the mic and call someone, it doesn't go back into RX until about a 
half a second after I un-key.  If I switch the VOX on the front panel 
back to PTT, the mic works as usual.  Is there some sort of VOX delay 
that holds the K3 in TX for a short while (~500 ms)?

     I thought VOX would be separate for phone and RTTY.  (CW works as 
always, no hanging in TX after the last dit or dah.)  I can live with 
this for awhile by simply toggling VOX on or off when I go between SSB 
and AFSK . . . just wondering if there is a setting somewhere that might 
be incorrect.
