Frequency Conversion
The tuning of a station can be expressed in frequency (kHz or MHz) or in
wavelength (meters). The following information can help you make the
necessary conversions.
1 MHz (million)=1,000 kHz (thousand)
To convert MHz to kHz, multiply by 1,000:
9.62 MHz x 1000 = 9620 kHz
To convert from kHz to MHz, divide by 1,000
2780 kHz / 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz
300 / 7.1 MHz = 42.25 meters
A Note on Image Reception
Radios work by simple mathematics. For example, most tune to a frequency
by mixing that frequency with another (local oscillator) frequency which
is slightly different. This mixing process primarily gives us the two
original frequencies, their sum, and their difference. Well, the radio's
