Short-Wave Report: Reception Versus Jamming
April 1959 Popular Electronics
younger than about 25 years old was alive when the "Iron Curtain" was
still in place. That was where the Communist countries were able to
keep outside information from the rest of the free world from getting
to their oppressed citizens. The Soviet Union, China, North Korea, and
other regimes had a vested interest in keeping people from learning
that not everybody lived in squalor as they did. The type of radio signal
jamming mentioned here was common. Modern communications has made information
dissemination ubiquitous, even in the still-Communist countries - like
Russia, China, and North Korea.

Reception Versus Jamming
several years one of the chief scourges of the short-wave broadcast
bands has been the jamming stations. It is virtually impossible to tune
across any of the main short-wave bands without hearing at least one
jammer and often as many as a dozen. These jamming stations are largely
located behind the Iron and Bamboo Curtains and their purpose is to
prevent listeners in those areas from hearing newscasts and commentaries
beamed to them from outside countries. (See article starting on page
41 of this issue.)
The jammers are often so strong that they also prevent listeners in
the U.S.A. from tuning in on certain channels. Many readers report that
this, alone, is enough to turn them away from their receivers in disgust.
at Kevin Jessup's listening post in
Westville, Ill. (right), is a Hallicrafters S-53A. He uses a six-meter
of Holstein, Iowa, DX's with a Hallicrafters
S-40B and a long-wire antenna.
The International Shortwave Club of London
has, for months, been asking their members to avoid listening to stations
that are located in countries responsible for jamming and, of course,
to avoid sending reception reports to those stations. Whether this has
or has not had any effect on the stations is difficult to ascertain.
On days when jamming signals blanket the regular short-wave bands, you
might try tuning in some of the off-beat channels where the jamming
is almost non-existent (although you may run into a good bit of Morse
code interference from time to time). These channels include many rarely
heard stations that may prove to be new countries for your log. Let's
check some of them. If you want to snag a rare one, try for
V3USE, Forest Side, Mauritius. This station wanders from about 14,980
kc. up as high as 15,020 kc. and is currently being reported on 15,018
kc. at 2300 with English news. You may need a lot of patience with this
one but it is being reported in Eastern states.
relatively clear channel is 9009 kc., where you can find Israel afternoons
between 1400 and 1600. Reports indicate that it is well heard in most
If you can understand Spanish, go after the Nicaraguans
in the 7000-kc. band. Some of these are: YNMS, R. Phillips, Leon, 7650
kc.; YNCA, R. Atlantico, Bluefields, last reported on 7755 kc.; and
YNRM, R. Musun, Matagalpa, 7593 kc. You may need a bit of extra tuning
for them as they seem to wander around a bit. Try during mid-to-late
If you can tune above 40 megacycles (40,000 kc.) ,
try for the British Broadcasting Corporation's television Channel I
(audio only) on 41,500 kc. Two stations, Crystal Palace and Divis, can
be heard late mornings and they are just a few cycles apart although
listed for the same frequency. (Your editor has both of them verified.)
Another TV channel that is usually well heard at the same time is the
French Channel II at Caen on 41,250 kc.
that can be found occasionally include: Beirut, Lebanon, on 8000 kc.
(varies up to 8036 kc.); a station in Ecuador, as yet unidentified,
on 8899 kc.; Radio Espana Independiente (Spanish Clandestine) on or
near 6948 kc.; and JOZ, Tokyo, 3925 kc. A real tough one to log is the
Falkland Islands station on 3958 kc., noted in Western areas around
Check this list the next time you are baffled
by the jammers. You'll find that you can have as much fun tuning the
off-beat channels as you will have in the standard bands. Be sure to
send reception reports; many of these stations are strictly regional
and reports from outside areas enable their engineers to know where
their signals are going. Let us know how you make out.
