How does one select a sweep width other than the default around 70 KHz? I
don't see any menu setting.
TIA,

> Hi Mark: As best I can tell by looking the sweep is in 250 Hz segments
with bandwidth cranked down to 100 Hz. . That is, on the narrowest sweep
range of 4.5 kHz there are just over two "digital blocks" per 600 Hz
indication. Skipping the 9 kHz sweep width to the 18 kHz width, there seem
to be 10 digital segments per 2.5 kHz segment with the 100 Hz bandwidth.

interested in tend to hang around fairly narrowly defined band segments. And
yes with a little practice you can usually tell by the bandwidth what sort
of signal you have indicated on the sweep.

a 5 kHz division on the sweep) wide, while a 75 M AM signal looks like it's
close to 8 kHz overall. The digital modes are usually two to three segments
wide. CLEAN slow CW shows up as a narrow spike a single segment wide, CLEAN
faster CW is somewhat wider - and some of the click boxes are three or four
segments wide.
