Actually  'tis the benefit of antenna diversity reception.

It was written,  and so it must be:

Been used by the telephone companies for decades.

Interesting,  I notice exactly the  same thing from here on Kauai with my
single triband beam on the main rcv channel of the FT-1000D,  and my
20 meter vertical feeding into the BPF-1.  Cleans up the audio, as
 seemingly perceived in my head,   and
from moment to moment one or the other is louder!!  I like antenna
diversity reception,  it is a great enhancement to DX'ing.  One of the
secrets of the Yaesu FT-1000D rig!
