[Elecraft] Odd power/ALC problem

[Don Wilhelm]

Tom,

Did you use K3 Utility in Advanced mode and check all the boxes and 
click the box to load all checked items?  Any other method will not work 
because the K3 is already loaded with the same level that you are trying 
to re-load.

I believe the filter offset for LSB/USB is controlled in the DSP code, 
so that must be force loaded to make any change.

73,
