Various kinds of 'junk' on the screen have been reported to be caused by
coax jumpers with poor shield contact at one or both ends. Try another
cable if you haven't already.

Hello all, I am trying to figure out why our P3 panadapter sometimes
but not always shows a group of vertical green stripes that cover
about 1/6 of the width of the screen. These stripes are not related
to RF frequency because if I switch bands they remain in the same
location. If I remain on one band and twirl the VFO knob, real radio
signals move into the green stripes but the stripes themselves are
immobile.
Sometimes these are not there at all. Sometimes they are near the
left of the screen, more often toward the middle.
Wayne gave some instructions for investigating this on PX3,but this
is P3. Any ideas?
Am I correct that these cannot be related to real RF interference due
to the above facts? Wouldn't real RF be frequency-related? We do
sometimes get RF interference that shows as periodic narrow lines on
the waterfall, but these wide stripes are different.
THANKS! Julie KT4JR
