WDER-AM 1320 DA Out Of Tolerance CLARIFICATION

[Dan.Strassberg]

I was not aware that WAZN ran 800W ND while it was installing its DA-2 setup
at 75 Concord Ave in Lexington, but if that was the case, 800W ND is
equivalent to more than three times the equivalent nondirectional power that
WAZN's 1400W daytime directional pattern effectively sends at 180 degrees
(that is, in the direction of first-adjacent WSAR). Using that same pattern
and power, WAZN sends the equivalent of more than 10 kW ND to the northwest
during the daytime (323 degrees, the radiation maximum). The night-pattern
maximum (to the southeast; 323 degrees), using 3400W is equivalent to ~25 kW
ND. Anyhow, WAZN provides a second example of STA parameters that exceed
signal strengths that either are licensed or are permitted via CP. Put
another way, the FCC apparently sometimes grants stations STAs that do not
fully protect the licensed operation of other stations.
