WMVX (ex-WNSH) granted 50 kW-D

[Dan.Strassberg]

Since field strength is proportional to the square root of radiated power,
going from 30 kW to 50 kW will increase the signal strength by only 29%. I
don't think the higher power is going to improve the signal by a great
amount. But in Provincetown, where I'm told that 1570 has a killer signal,
the 5 mV/m contour may move southward enough to encompass the entire
community. (There's a clear salt water path between the Endicott College
campus and the tip of Cape Cod but the 1570 ground system is on solid rock,
whose minuscule conductivity I believe necessitated a waiver of the normal
Class D minimum inverse-distance field.) Will the small improvement have any
effect on listership in P-Town? Does Provincetown have much of a Hispanic
population? My guess is that the intent of the increase is to do a little
better in Lawrence.
