Editing Morse code (section)

===Demise of commercial telegraphy===
In the United States the final commercial Morse code transmission was on July 12, 1999, signing off with Samuel Morse's original 1844 message, [[wikt:what hath God wrought|'''{{sc|What hath God wrought}}''']], and the [[prosign]] {{sc|'''{{overline|SK}}'''}} ("end of contact").<ref name=Maritime-Radio-Hist-Soc-pab1_7/>

{{as of|2015}}, the [[United States Air Force]] still trains ten people a year in Morse.<ref name=Swling-2015-12-10/>

The [[United States Coast Guard]] has ceased all use of Morse code on the radio, and no longer monitors any [[radio frequencies]] for Morse code transmissions, including the international [[medium frequency]] (MF) distress frequency of {{nobr|[[500 kHz]].<ref name=USCG-2011-Circ-1367-Amd/>}} However, the [[Federal Communications Commission]] still grants commercial radiotelegraph operator licenses to applicants who pass its code and written tests.<ref name=FCC-radiotelegraph/> Licensees have reactivated the old California coastal Morse station [[KPH (radio)|KPH]] and regularly transmit from the site under either this [[call sign]] or as KSM. Similarly, a few U.S. [[museum ship]] stations are operated by Morse enthusiasts.<ref name=Maritime-Radio-Hist-Soc-main/>
