I've narrowed down when the signal reporting gets changed. On my newly
built test system with MythTV v31 on Ubuntu 20.04.3 LTS my signals were
reported as ~100% on most of my channels using my Hauppauge WinTV quadTV as
it had for years on my production backend.

I added the ppa:mythbuntu/32 repository and upgraded to v32. The system
updated all 21 packages and everything was working as before but now on v32.

But when I use Watch Live TV all my reported signal strengths were between
40-50%.  So the change is MythTV v32 related and not the version of Ubuntu.
The OS remained at Ubuntu 20.04 with latest patches without any package
updates to Linux during this test.
