[Elecraft] PX3 problems

I think these problems are chronic, and have been occurring off 
and on for at least a year. (I've been ignoring them because for 
most of the time I use my K3 and P3, or I'm operating FT8 and 
the PX3 doesn't matter. Also, I'm lazy.)

Vertical smearing. It acts as if once a signal is displayed on 
the waterfall, it is displayed on every subsequent line of the 
waterfall. Everything is blurry as well. It seems to go away if 
I change bands on the KX3.

Horizontal smearing. It acts as if the signals on the waterfall 
are being modulated by a weak signal so the they get wider. This 
widening makes a CW signal about 3 times wider. This issue comes 
and goes with no obvious cause/relation to other things.

Any thoughts? Any fixes?
