[Elecraft] K3: cw/vox/PTT ver 2.02 - bug?

[Don Wilhelm]

Lexa,

I believe you are mis-interpreting What QSK DELAY does.  It does *not* 
increase the time before the onset of RF, but it does change the delay 
after a keyup condition.

The purpose of QSK DELAY is to keep the amplifier relays held in between 
code elements so one does not have to listen to the loud clacking of the 
amplifier relays.

The delay of RF output after keydown is currently fixed in the K3, but 
there is consideration being given to allow it to be user controlled in 
the future.  The adjustment range may be limited, so if you have 
transverters and preamplifiers that must have a longer delay to the 
onset of RF, the TX INH input would be required.

73,
