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

Earlier I thought I understood that setting the filter width on the KX3 to
maximum would yield a wide waterfall on PSK31, but there must be something
else too because now I have narrow waterfalls while the KX3 filter width is
still set wide. What am I missing? THANKS!
