FREQUENCY CONVERSION
A band is a group
of
frequencies. Bands are grouped according
to
their wavelengths and measured in meters. A station's tuning loca-
ti
on
can be expressed as a frequency (kHz
or
MH
z)
or
in wave-
length
(meters).
Amateur radio operators generally refer to the frequencies they op-
erate on using the frequency's
wavelength. For example, the 19-
meter band refers to the range of frequencies wi
th
waves about 19
meters
long.
