If you don't mind your code element lengths varying by ~10 msec (still 
an appreciable quarter of an element at the slow speed of 30 wpm), then 
that portion of the Brand-E user community that insists this isn't a 
problem are correct.

For everybody else, the solution to the problem (with the radio, not the 
user group) is to assert PTT.  Then the RF more faithfully follows the 
keying.

Yes, you'll have to let off the PTT for the rig to drop into receive, 
but since the K3's "QSK" is more of an inter-character - rather than 
intra-character - break-in, you literally aren't missing anything.
