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

[Scott Monks]

Now before you guys think I too am complaining--no, I just have a curious mind!

Two questions that I am sure you more experienced can help me with:

1. When I begin narrowing the DSP down, on filter 1 (2.7, std, offset -0.84) only the lower freq side moves.  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?

2. When seen on the P-3, on hi-cut-lo, if I move the lo side, the higher freq side moves, and if I move the hi side, the lower freq side moves.  On the K-3 display the expected side moves.  Again, is this normal?

I have the last production software installed.  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.

These only "bother" me because I know there must be a reason but I don't why it happens!  If curiosity is going to kill the "cat", don't tell me and I will just continue to be happy with my partial K-line!

Thanks for your patience,
