Depending upon whether you’re in range of any Low Power Television (LPTV) or Translators, you may still have broadcast signals reaching you on the frequencies numbered 38 and above for awhile. Plus also if you’re near an international border (Canada or Mexico).
Low Power TV stations (Non-Class A) and Translators are independent of the phases prescribed by the FCC. Also, Canada’s repack schedule has 14 phases, with the last one concluding 1/14/2022. I didn’t seek out information about Mexico.
Regarding the US non-phased transitions: “LPTV and TV translator stations may remain on their existing channels until they are needed by repacked stations or for those stations in the 600 MHz Band until they are notified by a new 600 MHz Band licensee that it is ready to commence operations or conduct its first field application (FFA) testing.” (https://www.fcc.gov/about-fcc/fcc-initiatives/incentive-auctions/post-auction-transition)
My quick Googling isn’t finding a hard and fast end date for these frequency changes. I did find this notation about how analog broadcasting is still being allowed into next year: “12 months after the completion of the 39-month transition period, or until July 13, 2021”. (https://docs.fcc.gov/public/attachments/DOC-356300A1.pdf Specifically, bottom of the PDF page 7, numbered as page 6, in footnote 27.)
For example, in my market (West Michigan), there’s one analog still going (the 3 Angels station in Grand Rapids), using RF48. They have an approved Displacement Construction Permit to go digital on RF27, expiring in July 2021. Their analog broadcast coverage is quite small, and doesn’t reach me in eastern Kent County–so I can’t confirm if they’re still on the air now or not.
In the Traverse City, Michigan area further north, the WWTV Digital Replacement Translator (DRT) apparently is still on RF40, with a construction permit to use RF25. Seemingly the buyer of their frequency hasn’t sent them a letter with a deadline yet (which happened to at least one DRT closer to me in late 2018–causing that one to go off-the-air for a few months until the tower crew and equipment was all available). Also, I believe the one analog (WXII-LP on RF12) is still chugging along, but with an approved Digital Companion Channel Construction Permit for RF30 valid into July 2021.
You’re very correct that US “Full Service” (full power) stations and Digital Class A low powers are scheduled to be completed in the 10 phases the FCC scheduled, ending on 7/3/2020. But these other broadcast stations weren’t in scope for the Federal Government’s coordination.
