UP to Zip Signal Main Page

Enter a Call Sign to find the signal strength of an AM or FM station (AM stations can be identified by their frequency in kHz or the all upper case city of license) 

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 is predicted. 50 dBu is the cutoff for prediction for this signal strength retrieving program.  Many stations may have coverage past the 50 dBu, however 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. 

Call signs occupy a six letter text field. For day operating AM stations, simply enter the stations' call sign. For night time AM stations enter the call sign followed by "-N".  For FM calls such as "WWWW-FM" enter the complete call i.e. "WWWW-FM". 

(Click the Facility ID link in the last column to link to the FCC's CDBS database for the selected station.)
