[Elecraft] K2 SSB ALC Problem

[Don Wilhelm]

Sanjin,

In that case, certainly try the resistor changes.  The change is 
reversible.  If the SSB power out is not up to what it should be after 
the change, then you will know that there is some other problem.
The K2 LED bargraph is almost as fast as an oscilloscope display - after 
the change, check the ALC indication and then place it in RF display 
mode - you should see the bargraph flicker at the peak power level.  If 
you need a reference level, press TUNE and it will show the CW level.  
The SSB signal should peak up to that same level.
