251.600 Pre Flight
346.500 Comm 1 "Channel 16"
Can anyone verify 251.600 tomorrow? They wouldn’t normally be using that; it was replaced by 346.500 several years back. If they did use it as a spare, they shouldn’t also use 346.500.
Button 16 is actually 284.250. The solos call “ready to push 16, Boss” on 346.500 (Button 18) when they are ready for takeoff.

See my post near the top for the ground ops channels; looks like they are mostly the same.
456.6500 might be unrelated, as the license shows a business trunked system. I had the FBO on 464.3375 in 2018 - they have a license for that and 462.075.
