I wasn't planning on posting anything anymore as the transition of ATSC 3.0 has slowed down probably due to the recession. I don't know if OTA ATSC 3.0 will ever be completed; streaming seams to be the way of the future.

However special note to those in the Welland area of Ontario:
"On August 14, 2020, WDTB‐LD was forced to go silent after the FCC informed WOGF that WDTB‐LD was causing interference to Canadian station CKVP‐DT."
WDTB has petitioned the FCC to broadcast on RF channel   , same as CITY-DT Toronto. I don't know what interference this will cause, if this goes ahead.  ROGERS will probably object.

P.S. Why is ROGERS allowed to operate 3 OTA stations in one market? They would save money if they consolidated onto one frequency.
