[Elecraft] Interpretation of P3 display

[Ron D'Eau Claire]

It is not unusual to see a wide variation in SSB signal bandwidths having
nothing to do with improper operation or distortion products.

Some rigs, especially older rigs, have wider filters or filters with much
more shallow skirts than others.

Then there are phasing rigs with only audio filtering, which might vary a
great deal -- especially vintage phasing SSB rigs. 

And, finally, there are rigs running ESSB which are wider on purpose. 

At the other extreme, some prefer a very narrow filter for SSB, sometimes
down to 1.8 kHz. This is usually done to condense as much RF into as narrow
a slice of spectrum as possible for maximum S/N at the receiver for a given
power.

Yes, I see similar and I would call it splatter.  Especially when it is
clear other stations are not doing this. Over driving something past their
SSB filters. On a local net where the are mixtures of vintage and modern the
vintage ones ( on this net) tend to be much broader and for sure they are
not over driving.
