I don't recall the sidetone itself being clicky but I did notice that 
when the S-meter was reading a signal level of S3 or higher there was a 
higher propsensity for a click on the 2nd or 3rd dit (or dah) when 
returning from sending a letter - it sounds similar to the AGC going 
from 0 to meet whatever level necessary, and it would not act fast 
enough.  However, with #52 pulled (I actually just slid the plug over to 
seat onto the connector with no wire attached to it) the performance is 
great!
