I am.  Usually ok, but recently it gave a little snap when I hit the key.
This can be caused by the rf from the K3 hitting the L4B before its slow relay is
closed.  So I increased delay TX DLY from 8 to 20 milliseconds and it
cured the problem.  My L4B has a transistor driver on the PTT line but
this is not supposed to be necessary with the K3.  But it doesn't change
the key up time like an external relay would, and the cost was zero.

What's your call, Keith?
