[Elecraft] K3: Pre switching older amps to avoid hot switching

[George]

Anyone have the following K3 info?

1.  When will the variable amp preswitching  feature will be activated?

2.  Will the range be up to 50ms?

3 . What is the amount of switching lead time for the K3s presently being shipped?

    ( I'm especially interested in Q3)

Thanks and 73
