[Elecraft] PSK31 waterfall width control

[Don Wilhelm]

Julie,

I just checked my KX3 using a broadband noise generator and Spectrogram 
to view the passband width.  With the WIDTH set to maximum, the passband 
extends from 250 Hz to above 3000 Hz (which should fill the waterfall on 
Fldigi).  I do not have Fldigi installed on my workbench computer, but 
that should not make any difference.

Use the numbers in the KX3 WIDTH display to judge the actual width - if 
you look only at the graphic on the display, it goes to its maximum 
width when the actual width is greater than 1.2 kHz.

The PBT knob normally alters the center frequency (FC).  Tap it to 
change the knob function to WIDTH.

73,
Don W3FPR
