Snip I'm not messing with you. This is basic terminology not something exotic. The majority of short wave broadcasts occur in designated bands of frequencies. The bands are identified by the inverse of a rounded frequency in the band. This is how the broadcast bands are identified. wavelength = speed of propagation/frequency In oder to calculate in meters the formula is wavelength in meters = (300 meters/sec) / (frequency in MHz/sec) so 60 meters is 5 MHz. The 60 meter band is 4.750 MHz to 5.060 MHz BAND MEGAHERTZ (MHz) KILOHERTZ (KHz) 120 m 2.300-2.500 MHz 2300-2500 KHz 90 m 3.20-3.40 MHz 3200-3400 KHz 75 m 3.90-4.00 MHz 3900-4000 KHz 60 m 4.750-5.060 MHz 4750-5060 KHz 49 m 5.950-6.20 MHz 5950-6200 KHz 41 m 7.10-7.60 MHz 7100-7600 KHz 31 m 9.20-9.90 MHz 9500-9900 KHz 25 m 11.600-12.200 MHz 11600-12100 KHz 22 m 13.570-13.870 MHz 13570-13870 KHz 19 m 15.10-15.80 MHz 15100-15800 KHz 16 m 17.480-17.90 MHz 17480-17900 KHz 13 m 21.450-21.850 MHz 21450-21850 KHz 11 m 25.60-26.10 MHz 25600-26100 KHz By knowing the wavelength of a frequency you get an understanding of the size of the resonant antenna to receive it. -- Telamon Ventura, California |
