April 1959 Popular Electronics[Table of Contents]
People old and young enjoy waxing nostalgic about and learning some of the history of early electronics. Popular Electronics was published from October 1954 through April 1985. All copyrights are hereby acknowledged. See all articles from Popular Electronics.
Nobody 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
For 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.
The receiver at Kevin Jessup's listening post in Westville, Ill. (right), is a Hallicrafters S-53A. He uses a six-meter doublet 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.
Another 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 areas.
Dave Lund, of Holstein, Iowa, DX's with a Hallicrafters S-40B and a long-wire antenna.
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 evenings.
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.
Other stations 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 1800-1900.
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.
At time of compilation all reports are correct. Stations often change schedules and/or frequencies with little or no advance notice. All times shown are Eastern Standard and the 24-hour system is used.
