Does anyone recognize this round object under the belly of a PA-24?

From a Comanche parts catalog, it's the ADF loop antenna (item 45) minus the aero cover (30):

That is probably the ADF loop antenna. To read properly, it must be installed so the little airplane's nose points in the direction of flight.
