Starting in 1938, the FCC created 6 MHz wide television channel allocations working around the 5-meter amateur band with channel 2 occupying 50–56 MHz. In 1940, television channel 2 was reallocated to 60 MHz and TV channel 1 was moved to 50–56 MHz maintaining a gap for the 5-meter amateur band. When the US entered World War II, transmissions by amateur radio stations were suspended for the duration of the war. After the war, the 5-meter band was briefly reopened to amateurs from 56–60 MHz until March 1, 1946. At that time the FCC moved television channel 2 down to 54–60 MHz and reallocated channel 1 down to 44–50 MHz opening a gap that would become the Amateur radio 6-meter band in the United States. FCC Order 130-C went into effect at 3 am Eastern Standard Time on March 1, 1946, and created the 6-meter band allocation for the amateur service as 50–54 MHz. Emission types A1, A2, A3 and A4 were allowed for the entire band and special emission for Frequency modulation telephony was allowed from 52. 5 to 54 MHz.
