I had a similar problem when I first got my P3. The symptom(s) centered
around the noise drifting upward. Hand on top would send it back down
to the baseline. One of the Elecraft techs [who I know well] sent me a
new jumper on the condition that I cut the old one into 5 cm pieces so
it didn't show up at a swap meet. The new one fixed the issues.
The P3 is really a tuneable receiver that covers most of the HF
spectrum. We just leave it tuned to the 8 MHz 1st IF. If the
cable/connectors are not really shielded well, it will pick up ambient
noise.

Trevor,
Try another coax jumper between the K3 and P3. I have heard of this
problem being caused by poor connection of the shield braid (or
low-quality braid) in the jumper.

I am sure I have seen some threads on this before so please accept
apologies If i am going over something twice.
Having moved to an area with a much lower noise level I note loads
of sprogs / spurious signals following me around on the P3
panadapter. Is there a common cause of these (im presuming they are
generated by the K3S) and anything I should/could be doing to get rid
of them?
