You're mixing apples and oranges. The figures you give for WFAN and WCBS are
"per kW." To make them comparable to the pattern rms values you give for
WRKO, you must multiply them by the square root of the ratio of the
station's power to 1 kW (that is, by 7.071 for 50-kW stations such as WFAN
and WCBS). Thus the values are 3015.64 for WCBS and 2685.26 for WFAN.
As for WRKO, since it is directional, the inverse-distance field at the
radiation maxima (at azimuths of 0 degrees--due north--and 150
degrees--south-southeast, toward Boston) must be well in excess of 
3000 mV/m at 1 km.
