Don't remember seeing this before in this list. Find the field strengths of AM day, AM Night and FM stations within U.S. postal zip codes throughout the U.S. This web program produces accurate radio station signal field strengths, organized by zip codes, from the FCC's CDBS AM and FM database, as of September 27, 2006. V-Soft Communications provides this data free of charge as a service to its customers and friends.

USE AT YOUR OWN RISK. Enter a US zip code to find the signal strength of AM or FM stations serving the location. AM stations can be identified by their frequency in kHz or the all upper case city of license. AM Night stations have the "-N" appended to their call signs. 100+ dBu Extremely strong 80+ dBu Very Strong 70+ dBu Strong Principal city coverage 60+ dBu Good coverage 50+ dBu Weaker Coverage - may have interference * Coverage predictions use the standard FCC method, directional antenna patterns, if used by the stations, and for FM stations the 30 arc-second NGDC terrain elevation database. AM daytime station coverage and nighttime coverage is predicted using the M3 ground conductivities curves. 50 dBu is the cutoff for prediction for this signal strength retrieving program. Many stations may have coverage past the 50 dBu. The majority of FM stations are protected from interference by the FCC only to their 60 dBu, any coverage past that signal strength value would depend on whether there are other stations causing interference, which cannot be reliably predicted using the standard methods employed herein. Many AM stations operating at night are subject to interference which is not considered by this _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
