Perhaps we could call it, "personalize our transmitted CW note?"  Sounds 
better than "dirty up."  And, this is NOT a request for a K3 firmware 
change to allow personalization of CW notes!

Rotary spark operators sometimes had a foot pedal similar to a sewing 
machine pedal with which they could "personalize" the note [such as a 
"note" was with a rotary spark gap TX] by speeding it up and slowing it 
down while sending.

What truly intrigues me is how they built receivers pre-De Forest. 
Spark gap TX is easy, before LORAN-C met it's death, several of the 
stations had reverted to the 21st Century equivalent of spark.  I really 
do not understand what the Titanic's receiver looked like.
