[Elecraft] PX3 Problem?

[Roger Meadows]

Sounds like a ground loop. I had something similar.  I unplugged the KX3 from the computer and it went away. I was able to use an USB hub and it was fine.

I have had my PX3 for a little over a year (I think). It has been used sparingly. Until this afternoon, it has worked perfectly. 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.

So, perhaps I have a failure that requires returning to Elecraft? Have any of you had the same experience?
