The title text makes a pun on "gyroscope" and a middle-eastern pita wrap called a "{{w|gyros}}", incorrectly taken to be plural by many non-Greek speakers.

In practice, periscope use is minimized because periscopes are still observable, but to a lesser degree. || An electron microscope seemingly mounted on a periscope.

Later, the fixed ''Bali'' antenna could act as a true periscope, in order to detect aircraft and ships that were using radar to hunt submarines.

Radio signals do not propagate well in water, so raising a radio receiver above the water would be necessary for listening to {{w|NPR}} (National Public Radio, a popular public radio network in the United States) or any radio station which is not in the {{w|extremely low frequency}} band.
