[Elecraft] [Elecraft_K3] curious behavior of the K3/P3, etc.

[bill conkling]

Hi/lo cut is usually used for ssb operation.  But I think K3 cw is lower than carrier so same applies.

The DSP switches to the 2.1 filter, reacting the same, but when it narrows to about 1.10 (within filter 2; 2.1, offset 0.0) it changes so that both low and high move equally.  Even narrowing continues through the 700 and 400 Hz filters.  The reverse occurs in the same way.   I have checked the offsets with the K3 program, and they are set as required.  On the K-3 display the "bar-thing" always seems to move equally on both sides.  Is this normal?

This was first noticed when I got the P3 and a "big screen", when in a contest I wanted to shift the receiver up to avoid a disturbing signal and found I had to move the hi side to move the lo side!  Now I am accustomed and just watch my screen to make sure I am moving outside of the interfering peak.
