OK, now I see it, down the right hand side of the graph, effective date December 12.
AND THERE IS A TOWER.
But this URL dated the same date
https://nfdc.faa.gov/nfdcApps/airportLookup/airportDisplay.jsp?airportId=PHLU
SHOWS NO TOWER.
My bad. I provided the chart for Molokai (PHMK) which is less than 8NM from PHLU. So, they were within radio range of the tower at Molokai.
MY FAULT for the confusion.
