[Elecraft] PX3 Problem?

[David Anderson]

One other thing, have you perhaps got the PX3 Noise Blanker switched on and the PX3 NB level turned up high? That causes spikes at the centre.  (I am not referring to the KX3 noise blanker)

Now I see a spike in the center of the display and periodic spikes across the entire screen. Almost all are symmetrical in frequency and amplitude about the center line. There are some that are not symmetrical.  I have plugged and unplugged all the cables, taking care to see that each is fully into the socket.
