I know this can't be right - 0.01 micro sV - 0.05 micro sV per hour, day or night. CPM 1-2.

Thoughts? Tube gone? Dead? Needs recalibration?

My veteran berkley Radionics has me at around 0.12uSv/hr, my Polimaster is about the same.

Thoughts, anyone?

The problem is related to the tube. It could be tube bad OR the tube voltage too low.

You can try to turn the tube voltage up and see if it fixes. Otherwaise you need to contact support@gqelectronicsllc.com for the warranty.
