To convert kHz to MHz, divide by
1,000. For example:
2780 kHz ³ 1000 = 2.780 MHz
To convert MHz to meters, divide 300
by the number of MHz. For example:
300 ³ 7.1 MHz = 42.25 meters
To convert meters to MHz, divide 300
by the number of meters. For exam-
ple:
300 ³ 42.25 meters = 7.1 MHz
BAND ALLOCATIONS
Certain bands are set aside for specific
purposes.
Amateur Radio Frequencies
Tuning to the amateur radio frequen-
cies can be interesting and helpful, be-
cause amateur radio operators often
broadcast emergency information
when other means of communication
break down.
Amateur radio operators use the fol-
lowing bands. Portions of these bands
are set aside for continuous wave
(CW) Morse code communication or
for single sideband (SSB) voice com-
munication, as shown below.

1,800–2,000 kHz: SSB

3,500–3,800 kHz: CW
3,800–4,000 kHz: SSB
40 meters:
7,000–7,150 kHz: CW
7,150–7,300 kHz: SSB
20 meters:
14,000–14,200 kHz: CW
14,200–14,350 kHz: SSB
15 meters:
21,000–21,250 kHz: CW
21,250–21,450 kHz: SSB
10 meters:
28,000–28,500 kHz: CW
28,500–29,700 kHz: SSB
