I have a question for the group regarding interpretation of the P3 display of SSB signals.
Primarily I use it to spot stations on quiet bands or spot openings on busy bands. But I am trying to gain a better understanding of what it is showing me regarding the quality of signals as well. I have my P3 set up to show the band width as a column and the span set to +/- 25. I have noticed that most SSB signals will remain within the bounds of the column. However, some SSB signals will exceed the width of the column and will resemble a pyramid, occupying several kilohertz above and below the column on voice peaks. The proximity of the station does not appear to matter as these observations apply to distant stations as well as local stations. Is this what is known as "splatter"? Is the station overdriving their transmitter or linear? Is their ALC or compression too high? Is the frequency response of their microphone too wide? A good friend of mine has a K3/P3 and we have discussed this at length and come to the conclusion that we really don't understand what we are seeing. Anyone on the list have comments as to what they have observed or an explanation of what we are seeing? Any relevant comments would be appreciated.
