==Uses and applications== [[File:2008-07-28 Mast radiator.jpg|thumb|[[Mast radiator]] of a commercial MF [[AM broadcasting]] station, Chapel Hill, North Carolina, USA]] A major use of these frequencies is [[AM broadcasting]]; [[Amplitude modulation|AM]] [[radio station]]s are allocated frequencies in the [[medium wave]] broadcast band from 526.5 kHz to 1606.5 kHz<ref>{{cite web |url=http://stakeholders.ofcom.org.uk/binaries/spectrum/spectrum-policy-area/spectrum-management/UK-FAT-Table-2008/ukfat08.pdf |title=United Kingdom Frequency Allocation Table 2008 |publisher=[[Ofcom]] |access-date=2010-01-26 |page=21 }}</ref> in Europe; in North America this [[Extended AM broadcast band|extends]] from 525 kHz to 1705 kHz<ref>{{cite web |url=http://www.ntia.doc.gov/osmhome/allochrt.pdf |title=U.S. Frequency Allocation Chart |publisher=National Telecommunications and Information Administration, U.S. Department of Commerce |date=October 2003 |access-date=2009-08-11 }}</ref> Some countries also allow broadcasting in the 120-meter band from 2300 to 2495 kHz; these frequencies are mostly used in tropical areas. Although these are medium frequencies, 120 meters is generally treated as one of the [[shortwave bands]]. There are a number of [[coast guard]] and other ship-to-shore frequencies in use between 1600 and 2850 kHz. These include, as examples, the French MRCC on 1696 kHz and 2677 kHz, Stornoway Coastguard on 1743 kHz, the US Coastguard on 2670 kHz and Madeira on 2843 kHz.<ref name="yachtcom">[http://www.yachtcom.info/Frequencies.htm MF/HF SSB Frequencies<!-- Bot generated title -->] {{webarchive|url=https://web.archive.org/web/20070906110613/http://www.yachtcom.info/Frequencies.htm |date=6 September 2007 }}</ref> RN Northwood in England broadcasts Weather Fax data on 2618.5 kHz.<ref>[http://www.hffax.de/Northwood-95.txt Amended Radiofax schedule]</ref> [[Non-directional beacon|Non-directional navigational radio beacons]] (NDBs) for maritime and aircraft navigation occupy a band from 190 to 435 kHz, which overlaps from the [[Low frequency|LF]] into the bottom part of the MF band. [[2182 kHz|2182 kHz]] is the international calling and distress frequency for [[Single-sideband modulation|SSB]] maritime voice communication (radiotelephony). It is analogous to Channel 16 on the marine VHF band. [[500 kHz|500 kHz]] was for many years the maritime [[International distress frequency|distress and emergency frequency]], and there are more NDBs between 510 and 530 kHz. [[Navtex]], which is part of the current [[Global Maritime Distress Safety System]] occupies 518 kHz and 490 kHz for important digital text broadcasts. Lastly, there are aeronautical and other mobile SSB bands from 2850 kHz to 3500 kHz, crossing the boundary from the MF band into the [[High frequency|HF]] radio band.<ref>[http://www.ntia.doc.gov/osmhome/allochrt.pdf U.S. Government Frequency Allocation Chart]</ref> An [[amateur radio]] band known as [[160 meters]] or 'top-band' is between 1800 and 2000 kHz (allocation depends on country and starts at 1810 kHz outside the Americas). Amateur operators transmit CW [[morse code]], digital signals and SSB and AM voice signals on this band. Following [[World Radiocommunication Conference]] 2012 (WRC-2012), the amateur service received a new allocation between 472 and 479 kHz for narrow band modes and secondary service, after extensive propagation and compatibility studies made by the ARRL 600 meters Experiment Group and their partners around the world. In recent years, some limited [[amateur radio]] operation has also been allowed in the region of 500 kHz in the US, UK, Germany and Sweden.<ref>{{cite web|url=http://www.500kc.com|title=The 500 KC Amateur Radio Experimental Group|website=500kc.com|access-date=5 April 2018}}</ref> Many home-portable or cordless telephones, especially those that were designed in the 1980s, transmit low power FM audio signals between the table-top base unit and the handset on frequencies in the range 1600 to 1800 kHz.<ref>{{cite web|url=http://totse.com/en/phreak/bugs_and_taps/tapphon.html|archive-url=https://web.archive.org/web/20090106001803/http://totse.com/en/phreak/bugs_and_taps/tapphon.html|url-status=dead|archive-date=6 January 2009|title=totse.com - How to listen to cordless telephone conversations|date=6 January 2009|access-date=5 April 2018}}</ref>
