Their maps DO correctly show the distances to the contours for the field
strengths they identify. Radio-Locator picked different field strength
values for the "local" etc contours than those used by the FCC, but that
doesn't invalidate the Radio-Locator maps.

And their choices are reasonable. For example on AM, a 2.5 mV/m signal
(Radio-Locator's local contour) does provide good service to a typical cheap
table radio inside a home in an urban setting.
