1) Mythweb TV-> TV-> Channel information and delete all channels that will
2) Mythbackend setup Channel Editor -> Rescan -> Set start and stop
frequencies. In this latest case I started at 32 and stopped at 33. I then
clicked yes to both questions.
3) Repeat for other channels
4) Run Mythfilldatabase when requested.

In my case I also used the opportunity to clean up some things on Schedules
Direct and my active channels but that is a different issue. In the SF Bay
Area there is a great resource https://larrykenney.com/sfonair2.html
