no position

I have always gotten them and although the 10.3.1.2 software seems to help, I still see them.

In this picture, it's happening on the ground though they happen in the air also.  I've never had one

happen on an approach, but I suppose one day it will.

Posts on this topic seem to be mostly around 2015, ex.:

with discussions of ferrite beads etc.  Since this 540 is from before then, I wonder if it might suffer from whatever was improved around that time.  

This tag says REV 02.  Does anyone know what hardware rev is current?

Likewise, I have one of the earliest units in the field and have never seen this.

It seems as though most issues like this boil down to the antenna or feedline.

FWIW, I see this message "frequently", but in expected/explained circumstances:  For instance, while powered up inside the hangar without a clear view of the sky, or for a minute or two after powerup after being off for a while.  Once a GPS fix is achieved, I don't see the message for the rest of the flight.
