[Elecraft] K1 Internally Generated Signal

[Letsrun100 at aol.com]

Referring to operating frequency calibration:
 
Page 41 of the manual reads, "In the case of the internally generated  
signal, tap W P M + or W P M - until the display reads 99.7."
 
Page 58 refers to "internally-generated band edge signals".
 
I also noticed the K2 manual mentions the "internally generated signal" on  
page 57.
 
I can't seem to find it. Does the K1 really have an internally generated  
signal?
 
After 50+ years in "non-active status" I recently finished building #3252  
and have made several contacts including Columbus, OH, Austin, TX and Paris  
(France).
 
I'm very happy with my new rig. My CW is a little rusty, but will  improve 
with practice.
 
Thanks,
Jim
