AM Broadcast Radio Stations
AM stands for "Amplitude Modulation", which refers
to the means of encoding the audio signal on the carrier
frequency. In many countries, AM radio stations are known as "mediumwave"
(MW) stations. AM stations are also sometimes referred to as
"standard broadcast stations", since AM was the was the first form used
to transmit broadcast radio signals to the public.
AM Query
-- Technical information about radio stations (such as power or
whether station is directional)
Agreements with Canada related to broadcasting.
Agreements with Mexico related to broadcasting.
AM Stereo. Short notes on AM Stereo.
Antenna Structure Registration -- ASRS Registration, ASRS Query, TOWAIR
Anti-Drug Abuse Act Certification
must accompany all requests for Special Temporary
Authority (STA). Failure to provide this certification
may result in processing delays.

an AM transmitter site, within which tall structures
may have an effect on an AM station's emissions (see 47 CFR 73.1692) Use the AM Query to locate stations first. This program can also be used to
find acceptable locations for the main studio (see 47 CFR 73.1125).

Construction Permit Information
Sheets are sent along with the granted
construction permit to new AM and FM
stations and modified AM and
FM stations.
Consummation of Assignments or Transfers -- Licensees and permittees must
provide notification to the Commission of the consummation of an assignment
or transfer.

broadcast stations against Class A AM stations.

Daytime-Only AM Stations -- New daytime-only AM stations will not be
authorized by the Commission. AM daytime-only authorizations for new stations
were discontinued on December 1, 1987. See Unlimited Time Operation by Existing AM Daytime-Only Radio Broadcast
Stations, Discontinuance of Authorization of Additional

applications and FM noncommercial educational applications.

Facility ID Number for Broadcast Stations
-- A unique number has been assigned to each AM, FM,, LPFM, TV, LPTV,
translator, and booster station. This number
is being employed to provide an unvarying reference between
various databases at the Commission, and to minimize discrepancies caused
by call sign or facilities changes. The Facility ID Number for a broadcast
station may be determined by using CDBS. We encourage the use of this number, along with the station
call sign and file number if appropriate,
on the cover page of all documents pertaining to particular
broadcast stations submitted to the FCC.

in broadcasting (Localism Task Force)
Loop Antennas can improve AM radio reception,
by increasing the received signal presented to the radio antenna, and by
reducing interfering stations' received signal strengths. These can be
commercially purchased or made inexpensively at home. Search for
MW loop antenna or
mediumwave loop antenna
in your favorite Internet search engine to see the
possibilities.
