FREQUENCY

CONVERSION

The location of a station can be ex- pressed in frequency (KHz or MHz) or in wavelength (meters). The following in- formation can help you make the neces- sary conversions.

To convert from MHz to kHz, multiply by 1,000.

For example:

9.62 MHz x1,000=9,620 kHz

To convert from kHz to MHz, divide by 1,000.

For example:

15,500 kHz/1,000 = 15.5 MHz

To convert from MHz to meters, divide 300 by the number of MHz.

For example:

300/12 MHz = 25 meters
