FREQUENCY
CONVERSION
A band is a group of frequencies.
Sometimes, bands are grouped ac-
cording
to
their
wavelengths,
meters. The tuning location of a station
can be expressed as a frequency (kHz
or MHz) or a wavelength (meters).
Amateur radio operators generally re-
fer to the frequencies they operate on
34
using the frequency's wavelength. For
example, the 19-meter band refers to
the range of frequencies with waves
about 19 meters long.
Use the following equations to convert
kHz, MHz, and meters.
To convert MHz to kHz, multiply by
1,000. For example:
To convert kHz to MHz, divide by
1,000. For example:

available
To convert MHz to meters, divide 300
by the number of MHz. For example:
To convert meters to MHz, divide 300
by the number of meters. For exam-

Tuning to the amateur radio frequen-
cies can be interesting and helpful, be-
cause amateur radio operators often
broadcast
when other means of communication
break down.
9.62 MHz
1000 = 9,620 kHz
2780 kHz
1000 = 2.780 MHz
