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

[Don Wilhelm]

Scott,

When receiving in lower sideband, the AF highest tones are on the lower 
side of the passband display on the P3 - lower than the carrier.
The audio pitch is the difference between the carrier and the tone.
The Hi-cut moves the high end of the resulting audio, and in order for 
that to happen the lower edge of the passband shown on the P3 must move 
closer to the carrier.

I hope that helps.

73,

Thus, if I want to narrow my bandwidth to avoid a station above the desired one, I must adjust the lo-cut (I can see this happen on the P3).  This occurs on all bands on CW.
