[Elecraft] Is there a reason the receive is so Skinny

Larry,

Use Hi-Cut and Lo-Cut rather than Width and Shift and you will have much 
better luck.
You can set the Low end down to 0.00 if you want, and the High end to 
4.2 kHz.  Each end of the DSP filter width is independent when using 
Hi-Cut and Lo-Cut.  The low end response of the audio stages will be a 
limiting factor as well as the low pass filter in the audio path to keep 
high frequency white noise at bay.

I do not operate ESSB, so I have not measured the response with the DSP 
filter set that wide, but try it and see if that helps.

When I, and other look at my signal I am in fact transmitting out to 4K when measured on a spectrum analyzers. But when I look at signals myself on my receiver band pass display on the SA, all I can see is signals out to about 3.5 or a little better. I have the center frequency set at *155. I was told that is what it is supposed to be set at. If I move the center frequency up to 200Hz yes I can receive up to 4K but the bottom end amplitude is way down and when I try to play that audio back via the DVR everyone says they have lost their bottom end. What am I doing wrong? Are there other filters I should be using. I or none of the other guys I know how to set up the K3 to faithfully capture receive audio and play it back with frequencies below 200Hz, so if you know how to maintain the same amplitude of signal on the receive low end that matches the transmi
