I always have wanted to know how much power are stations allowed to
operate.
I remember while living in Mexico, listening to XEWA 540AM, they used
to operate at 150,000 watts day and night, but now they are less than
that, probably 5000 watts or something.

150,000 day and night.

XEW 900 is well known, they use 250,000 watts and say they cover most
of North America.

They say nothing like that. The signal had been dropped to 100 kw for many
years, but due to high man made interference in Mexico City, they upped it
again to provide good coverage of the Mexico City metro area.

XEW 900 is listed at the Secretaria de Comunicaciones y
Transportes(www.sct.gob.mx) with 250 kW, along with other 3 more
stations with more than 50 kW(XEB 1220 100 kW, XEEP 1060 100kW, XEX
730 100kW). I remember listening to XEG 1050 from Monterrey, the
signal sounded better than some locals and but only at nights.
Its a shame that the Secreataria doesnt provide coverage maps for the
stations, it would be nice to see a coverage map for a 100kW or a
250kW.
Is there a way to make a map with the Effective Radiated Power, Height
above Avg. Terrain and Antenna Pattern?
XEW 900 broadcast over the Internet at www.esmas.com/wradio. The site
used to stream a few other FM radios, it dropped them and now only has
W Radio and other Pop station.
The promos of XEWA 540 used to say the covered North Mexico and the
South of the USA, and they fed their signal to regular satelite, you
could hear either a Televisa channel or the station. Satelite radio?
