[Elecraft] PX3 - KXPA100 problems

[Guillermo Sobalvarro via Elecraft]

I am frequently getting a "COULD NOT SAVE PARAMETER" message when 
turning the select knob on the PX3 to QSY up or down.  The display 
resets and the waterfall starts over from scratch.  Sometimes it is 
almost right away when movement starts or after a long stretch. Seems to 
just happen at any aleatory time.  Same on any band.  Have firmware 
version 01.16 installed.  Just reloaded it.  This problem has been 
happening since I changed to version 01.16.

Another thing now happening is that when I try to capture an image from 
the PX3 it fails, freezes the PX3 display and after a minute or so the 
KPAX100 shuts down and PA MODE goes to OFF. After that the PX3 display 
starts working again and I am able to capture the screen once more.  If 
I turn PA MODE ON the amp comes on and if I try to capture an image 
again the whole process is repeated.

I have re-done the cabling and all seems correctly connected.  Any ideas?
