I think he's discovered one of the non-benefits and is

The exciter should NEVER be run full time.
A Micor exciter will develop 400 milliwatts, that's 0.4 watts and that much
loose RF running around loose in the station is asking for trouble.
Running the channel element full time is often done, but not a good idea,
it's much better to switch the

Joe answered your question accurately. The benefit of running the oscillator
all the time is stability. It won't hurt anything to have the oscillator
running all the time as long as the exciter is not keyed (Keyed A+ active)
