The shibboleth was off your post. Maybe Talamon was messing with me
because I'm new and wouldn't be able to figure out the meter
designations he gave. Been awhile since college.


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.
