[Elecraft] K3 Bandwidth Offset with Latest Firmware

[Don Ehrlich]

Ever since loading the latest firmware this problem has occurred:

I am listening to a cw signal with the bandwidth set to maximum (2.8 Khz on 
the display)
I have centered a cw signal in the exact center of the cwt display .. I am 
exactly on frequency.
I have the bandwidth display centered using the shift control.

Then I reduce bandwidth slowly and when I get down to about 500 hertz the 
signal nearly disappears.  I can recover it using the shift control (about 
FC 35 on the display) but as I continue reducing bandwidth more and more 
shift is needed to hold the signal until at about 200 hertz bandwidth there 
is no signal left and the shift control is no longer effective.

Before the last firmware upgrade I could crank the bandwidth down to 50 
hertz while everything remained centered on the display.

I have checked and rechecked all filter settings.  They are all as I had 
them set up originally.

What has happened?
