I updated my HP-1 using Sentinel this morning. After doing that, I started PowerPatrol and read the HPDB from the HP-1. It loaded 67 states, 3866 counties, 7998 systems, but 0 channels. It seems no details were loaded for any county.
If I expand out the Cobb county, Georgia entries there is nothing listed for Cobb, Businesses, Hospitals, etc. The right side panel is blank. But they are shown on the HP-1 itself and in Sentinel.
The saved georgia.hpd from an earlier update was 593 KB, from this save it is 33 KB.
