I just googled 'tv broadcast frequencies NYC changes 2018' and got 
several hits, although real numbers seem well buried. 'fcc repack' might 
be a good phrase.

If you find the new frequency, mythtv-setup has a 'Transport editor' 
that should let you enter that and rescan only multiplexes that you have 
lost;  but of course the menus we see are likely to be different.
