20-227.fm Page 12 Wednesday, August 4, 1999 10:13 AM Use the following equations to convert kHz, MHz, and meters. To convert MHz to kHz, multiply by 1,000. For example: 9.62 MHz ¥ 1000 = 9,620 kHz To convert kHz to MHz, divide by 1,000. For example: 2780 kHz ³ 1000 = 2.780 MHz To convert MHz to meters, divide 300 by the number of MHz. For example: 300 ³ 7.1 MHz = 42.25 meters To convert meters to MHz, divide 300 by the number of meters. For example: 300 42. ³ 25 meters = 7.1 MHz BAND ALLOCAT
