How radio beacons helped aircraft find their carriers

When did the US Navy begin using radio beacons to help aircraft navigate back to carriers?

The Royal Navy used them increasingly around 1936-37, and the US Navy followed not long afterward.

Practical Royal Navy carrier-beacon use dates to around 1936-37, with American adoption only a little later. The system gave returning aircraft a radio reference for locating a moving ship beyond visual range. Implementation required suitable electrical supply and equipment high in the carrier, so it was not a trivial add-on to every earlier hull. Its presence during the Taranto attack illustrates how late-1930s electronics directly supported long-range night carrier operations.
