[Elecraft] K3 TX delay

[Don Wilhelm]

Igor,

Please explain how the 8 ms is relevant when using PTT instead of VOX.

In PTT state, Keyout follows PTT (not the keyclosure) - so the amplifier 
relay circuit should be closed
as long as the operator closes the footswitch or whatever is used for 
PTT first.  Keying will most likely begin long after the footswitch is 
activated.  In other words, the 8 ms is not relevant, and no hot 
switching should occur.

73,
