Narrative:

I forgot to turn on my ads-B for this flight. Climb and descent phases were inside the ZZZ class B veil; but not in class B area. I was using my mode C transponder.I have an ads-B that powers on with the nav lights. I forgot to turn on the nav lights. I'm still getting used to operating with ads-B out. I was also down for 2 months for my annual inspection; partly due to unavailability of my ia because of virus concerns. As this flight was a post-maintenance flight and a windy day; I was concerned about the windy conditions and the best procedure for working with the tower to climb overhead the airport for the initial climb and checkout. (Working with the tower was a non-issue; they are great).I need to revise my pre-taxi; runup; or before takeoff checklist to include ads-B (the placard on my panel is apparently not adequate). My checklists are laminated to back of my flight clipboard; so not easy to revise and still on the to-do list.
