In 1909, Edward Payson Weston walked from big apple to San Francisco, masking round forty miles an afternoon and greeted by means of wildly cheering audiences in each urban. the recent York instances referred to as it the "first bona-fide stroll . . . around the American continent," and eagerly chronicled a trip within which Weston was once beset by way of fatigue, mosquitos, vicious headwinds, and brutal warmth.

2). In this case, both the equipment and its location are considered the EUT. The radiated emission test results are unique to the installation site because site containment properties affect the measurements. The ac powerline conducted emission test results also may be unique to the installation. However, where testing of a given system has been accomplished at three or more representative locations, the results may be considered representative of all sites with similar EUTs for the purposes of determining compliance with emission requirements (if allowed in the procuring or requirements standard).
Mutual coupling correction factors for 10 and 30 m are under consideration. As an interim procedure, site adequacy can be assessed by considering these correction factors to be equal to zero for such geometries and for all measurements using a broadband antenna.

Separation distances R, are measured with respect to the center of the transmit and receive antennas.
AC powerline conducted emission measurements AC powerline conducted emission measurements shall be made, unless otherwise speciﬁed, over the frequency range from 150 kHz to 30 MHz to determine the line-to-ground radio-noise voltage that is conducted from all of the EUT current-carrying power input terminals that are directly (or indirectly via separate transformers or power supplies) connected to a public power network. These measurements may also be required between 9 kHz and 150 kHz. In the United States, the FCC powerline conducted emission requirements for unintentional radiators cover the frequency range of 150 kHz to 30 MHz.
