LISTENING HINTS
Listening to shortwave radio can be very exciting. Newscasts from a
country where important events are taking place give you a sense of
immediacy that local newscasts seldom deliver.
Although shortwave listening requires no special knowledge, you might enjoy
it more if you read some of the numerous books available on this subject.
There are also several periodicals that give listening hints and seasonal
program schedules.
The following information might also help you organize your listening
efforts.
SW BAND ALLOCATION
Certain portions of the radio spectrum are set aside for specific
purpose.
Ham Radio Frequencies
Ham radio operators often broadcast emergency information when other means
of communication break down. Ham operators can transmit in continuous wave
or single sideband. This receiver cannot receive single sideband signals.
However, if you understand Morse code, you can listen to ham transmissions
in the following continuous wave frequency ranges.
3,500-3,800 kHz
7,000-7,150 kHz
14,000-14,200 kHz
21,000-21,250 kHz
28,000-28,500 kHz
International Radio Frequencies
International commercial broadcasts are found in the following bands.
Programming (often in English) usually contains news, commentaries, music,
and special features reflecting the culture of the broadcasting country.
You might find it easiest to hear these broadcasts during 6:00 p.m. and
midnight (your time).
NOTE: European stations often list a frequency by giving its wavelength.
For example, the 19-meter band refers to the range of frequencies
whose waves are about 19 meters long.
Band Frequency Range
120 meters* 2.300-2.495 MHz
90 meters* 3.200-3.400 MHz
75 meters* 3.900-4.000 MHz
60 meters* 4.750-5.060 MHz
49 meters 5.950-6.200 MHz
41 meters** 7.100-7.300 MHz
31 meters 9.500-9.900 MHz
25 meters 11.650-12.050 MHz
21 meters 13.600-13.800 MHz
19 meters 15.100-15.600 MHz
16 meters 17.550-17.900 MHz
13 meters 21.450-21.850 MHz
11 meters 25.670-26.100 MHz
* These bands are reserved for stations in tropical areas.
** Ham operators and international stations share 7,100-7,300 kHz.
Interference is heavy in this range.
Time Standard Frequencies
The following frequencies announce the exact time of day at specified
intervals.

FREQUENCY CONVERSION
The tuning location 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.
To convert from MHz to kHz, multiply by 1,000. For example:
9.62 MHz x 1000 = 9620 kHz
To convert from kHz to MHz, divide by 1,000. For example:
2780 kHz
-------- = 2.780 MHz
1000
To convert from MHz to meters, divide 300 by the number of MHz. For
example:
300
------- = 42.25 meters
7.1 MHz
TIME ZONE MAP
Most software stations announce broadcast times in UTC (universal time
coordinate). The time zone map on the back of the receiver shows the
different between UTC and each time zone.
To determine your local time, add or subtract the specified number from
UTC. During daylight saving time, subtract 1 more hour.
