Cold War DX and Tactical Callsigns

by Dan Greenall

During the Cold War years, many different signals could be found on shortwave that cannot be heard today. For example, there were two Germanys, several broadcasters from the USSR not including Radio Moscow, Radio Free Europe and others.

I have uploaded audio clips of these stations and others to the InternetArchive.

Here are a few of the links.

If you were adventurous like me, willing to tune outside of the regular assigned broadcast bands, and flip the BFO switch “on”, stations with odd sounding names like Giant Step, Sky King, Fanfare or Ivanhoe could sometimes be heard. These were typically tactical calls used by the U.S. military.

I recently dusted off an old 3-ring binder to look up what were some of the tactical callsigns that I was able to log from my southern Ontario listening post. They included Missionary, Toreador, Democrat, Retail, and Capsule.

My old recordings of stations “Pawnee” and “Fanfare” can be found on the Internet Archive here:

Pawnee:

Fanfare:

Information about these stations was hard to find, however, radio hobby magazines and SW club monthly bulletins were a good place to look. I have reprinted (below) some related material from Communications World magazine, which ran from 1971 to 1981.

CW Fall-Winter 1973 pages 32-3

“The Navy also has its point-to-pointers, including NSS, Washington D.C.; NPM, Pearl Harbor, Hawaii; and NPG, San Francisco. Overseas there are Navy stations in many locations, such as Naples, Italy (NNI), Londonderry, Northern Ireland (NST), Roosevelt Roads, Puerto Rico (NRR), San Miguel, Philippines (NPO), and elsewhere. Some military stations use tactical call names, rather than call letters, which makes the DXer’s hopes of identifying them rather slim. For security reasons these stations identify with names such as Overland, Kingfisher and the like. These call names are changed frequently and seldom is the hobby listener able to figure out just where the station he’s hearing is located. Some of these identifiers have been used so consistently, over the years. that DXers have managed to figure out their real identities. Toreador, for instance, is a name used by Navy Operational Radio, San Francisco; Pacific Radio is at Pearl Harbor; Ivanhoe is the U.S. Naval Communications Station, Norfolk, Virginia; and a whole series of stations using the code name Raspberry (as in Raspberry Jax, located at the Naval Air Station, Jacksonville”

CW Spring-Summer 1975 page 36

“SWLs will soon note that the armed forces don’t always use call letters. Instead, tactical call signs may be used to identify the station. You might, for instance, hear a station calling itself Ivanhoe or Capsule. Looking Glass or Migraine. Some tactical calls are changed frequently, others are used year after year and, as a result, no longer pose identification problems for the utility SWL. “Ivanhoe” is the identifier used by the Navy’s important Norfolk, VA base. Navy installations in Morocco. Iceland and Spain identify as “Fanfare,” “Port Call,” and “Pawnee,” respectively. The U.S. Air Force’s Strategic Air Command (SAC) has for years maintained a regular airborne alert. It is no military secret that at any time, day or night, SAC has jumbo bombers aloft—supposedly loaded with nuclear armaments—in readiness to retaliate should this country ever come under attack from an enemy. Clearly it is essential that these planes keep in continuous contact with ground command stations. Shortwave radio is one of the means employed. This SAC radio network is known as Sky King. Coded communications pass between SAC bases and the jets probably several times each hour. SWLs who stumble on these transmissions will hear, as part of the routine radio traffic, authenticator codes, usually two phonetic letters such as “Alfa-Tango.” The purpose of these codes is to assure plane commanders that the rest of the message is genuine. Various Air Force bases identify themselves in radio communications either by base name, such as “Hickam” (Hawaii’s Hickam Air Force Base), or by tactical calls. “Democrat” is used by March AFB, CA, and “Retail” is the call of Barksdale AFB, LA. SAC also has a flying command post, a back-up measure that supposedly would take command of SAC forces should “a nuclear attack wipe out the headquarters at Offutt AFB, NE. The command post in the sky uses the tactical call “Looking Glass.” Some SAC frequencies to watch are 6,762, 9,027, 11,220, 13,245, 14,744 and 17,875 kHz. There are other Air Force frequencies to watch for plane-to-ground. and vice versa, transmissions. Among them are 6,738, 8,764, 8,988, 9,020, 11,200. 13,201 and 17,993 kHz. “Raspberry” is a network tactical call used by naval air stations. “Raspberry Miramar” is the station at Miramar NAS, CA, and “Raspberry Jax” is Jacksonville, NASFL. You can find naval air communications in the 6.7, 8.7, 8.9, 11.2, 13.2 and 15.0 MHz frequency areas.”

CW (Fall-Winter 1976) pages 19-20

“The list of tactical calls is as long as your arm and most DXers find it very tough to connect a certain call with a particular service or military base. But here is a partial list of calls used by Air Force, Navy and a few Army operations. (Bergstrom AFB, TX), “Condor” (land mobile units), “Raymond 6” (George AFB, CA), “Raymond 24” (Little Rock AFB, 4LR). Pacific Missile Firing Range Network: “Plead Control” (Pt. Mugu, CA), “Outrider Control” (Barking Sands, HI). Strategic Air Command: “Skyking” (general call for airborne aircraft), “Outway” (Offutt AFB, NE), “Retail” (Barksdale AFB, LA), “Democrat” (March AFB, CA). Other Air Force “tacticals”: “Beaver Operations” (Ellsworth AFB, SD), “Letterman” (Hickam AFB, HI), “Hornpipe” (Cannon AFB, NM), Air Force Tactical Air Command: “Mainsail” (general call), “Fireside 1” (Langley AFB, VA), “Fireside 5”  “Glucose” (Seymour -Johnson AFB, NC), “Lactose” (Shaw AFB, NC), “Fertile” (Homestead AFB, FL), “Acrobat” (Andrews AFB, MD), “Ringmaster” (NORAD Hq, Cheyenne Mt., CO), “Gull Monitor” (Keesler AFB, MS), “Format” (McGuire AFB, NJ). Navy Atlantic Command: “Ivanhoe” (Norfolk, VA), “Hampshire” (Ft. Allen, Puerto Rico), “Sheriff” (Bermuda) “Phenomenon” (Jacksonville, FL). Navy Pacific Command: “Butterfield” (San Diego, CA), “Dunkirk” (Honolulu) Other Navy “tacticals”: “Climax” (USS Enterprise), “Eagle Cliff” (USS .John F. Kennedy), “Jitterbug” (Balboa, Canal Zone), “Artesia” (Keflavik, Iceland) “Orange Juice” (Guam), “Missionary” (Norfolk, VA), “Top – hand” (Chief of Naval Operations), “T – Bone” (Adak, AK), “Sleepy Hollow” (Cutler, ME). Army “tacticals”: “Agitator” (Ft. Bliss, TX), “Civil Genius” (Ft. Huachuca AZ), “Popeye” (Ft. Bragg, NC), “Avon Studio” (Ohio National Guard), “Contact Tippic” (Indiana National Guard), “Flame Ivory” (Pennsylvania National Guard).”

I wonder if anyone else recalls hearing these? Please comment!

A DXer Looks Back at the Voice of America

by Dan Greenall

50 years ago, Voice of America broadcasts could be found all over the shortwave dial.

In addition to a number of transmitter sites located stateside, the VOA used to broadcast from a number of other facilities located in overseas countries in order to help get its signal into all corners of the globe.  Many of these “relay” stations made for challenging DX catches and there was even an award offered by NASWA to those providing sufficient proof of reception of them all.  An example of this can be found on this link: https://k5nd.net/2011/06/voice-of-america/

The familiar tune of Yankee Doodle (heard at the beginning and end of a transmission) along with station ID in English would often include the particular transmitter site in use.  Several old recordings of these can be found on my links to these on the Internet Archive.

Technical staff hired to help maintain equipment at overseas facilities were often licensed amateur radio operators. See the attached scans of two QSL cards from amateurs who worked at the station near Monrovia, Liberia.

Most of the various VOA transmitter sites are listed below. Some include links that will lead to related historical information, articles and/or photographs and are well worth exploring.

VOA Greenville NC  

VOA Bethany OH

VOA Dixon/Delano CA

VOA Marathon, FL

VOA Wooferton UK

VOA Kavala Greece

VOA Thessaloniki Greece

VOA Rhodes, Dodecanese Islands

VOA Monrovia, Liberia

VOA Tangier, Morocco

VOA Okinawa, Ryuku Islands

VOA Poro/Tinang, Philippines

VOA Udon Thani, Thailand

VOA, Sri Lanka

VOA Sao Tome

VOA Botswana

A year ago, in January 2025, I made a couple of recordings, using remote SDR receivers, of some Voice of America programs being broadcast from their Botswana transmitter site.  These have been uploaded to archive.org and can be found here: https://archive.org/details/voa-africa-via-botswana-relay-january-19-2025

Since March 16, 2025, it seems the only former VOA transmitters being used are Greenville, NC (Radio Marti), Tinang, Philippines (Radyo Pilipinas world service), and Wooferton, UK (BBC and others).

Taiwan on Shortwave – Then and Now

by Dan Greenall

For nearly a half-century, The Voice of Free China broadcast programs via shortwave to a worldwide audience from Taipei, Taiwan. As a relatively new SWL in the early 1970’s, I was always excited to hear English language programs from that part of the world, far away from southern Ontario, Canada, where I lived. There was no relay from WYFR or Radio Miami International at that time, so the signal from Taiwan needed to travel over 12,000 km (7500 miles) to reach my receiver.

I made this recording of their interval signal and sign-on in early 1971.

In 1998, the name of the station changed to Radio Taipei International, then again in 2003 to Radio Taiwan International.

Today, Radio Taiwan International continues to offer programs on shortwave in a number of languages from a transmitter in Taiwan, though there appears to be only one English-language broadcast per day, that being from 1600 to 1700 hours UTC on 9405 kHz. Here is a recording of the station signing on at 1600 UTC on January 1, 2026 using a remote SDR located in Japan:

And here they are signing off for the day on December 27, 2025 at 1700 UTC on 9405 kHz, again using a Kiwi SDR in Japan.

 

The station is received well in southern Ontario during their daily 2200 UTC broadcast in Spanish on 15770 kHz. This transmission is aired using the facilities of Radio Miami International in Okeechobee, Florida. The Kiwi SDR used for this recording is located in my hometown of London, Ontario.

Some holiday reading for shortwave listeners

by Dan Greenall

Attention all SWL’s!   For those of you with a little extra free time over the holiday season, I would highly recommend having a look at two books that were written by a couple of very respected DXer’s from the past.  They are both available on the Internet Archive and their respective links can be found below.

Shortwave Voices of the World by Dr. Richard E. Wood   (1969)

I have mentioned this one before, but in case you missed it, you will find it here.

The World in My Ears by Arthur T. Cushen   (1979)

Newly uploaded, this one comes in two parts.  Part One describes his early days and how his listening began, while Part 2 gets into the hobby in general.

Happy reading!

Check Your Time with the LM Chime

by Dan Greenall

Shades of the 1970’s.  Commercial AM radio (in English) the way it used to be. Heavy on nostalgic music from the 1960’s to the 1990’s, plenty of good old style jingles, and of course, the LM chime every hour.

Decades ago, the “LM” used to stand for Lourenco Marques Radio as the station was based in this city in Mozambique. Today, it is Lifetime Memories Radio, and broadcasts to Maputo and the surrounding area, where it can be heard on 87.8 FM. The station also broadcasts on 702 kHz medium wave from a transmitter near Johannesburg, South Africa, and can be heard worldwide via Kiwi SDR or online stream here   https://lmradio.co.za/

In addition to the live stream, be sure to read about the rich history of the station that began in 1936. The station was shut down in 1975 when Mozambique gained independence, but has re-emerged in the 21st century.  A visit to the LM Radio museum is well worth the trip.  https://lmradio.co.mz/history/

In 1973, I was able to hear Radio Clube de Mocambique on 4855 kHz shortwave from here in Canada.  If you listen closely, you can hear the LM chime.

Give them a listen, but first, check out these sample recordings made between November 27 and December 8, 2025, through a Kiwi SDR located near Johannesburg:

Radyo Pilipinas World Service Back On The Air

Many thanks to SWLing Post contributor Dan Greenall, who writes:

Hi Thomas

As per the announcement on the SWLing Post, Radyo Pilipinas did indeed return on the air December 1 at 0200 hours UTC on the announced frequencies on 12020, 15640 and 17665 kHz. I was able to hear all three frequencies quite well using the LA6LU SDR in Thailand, and made this 11 minute recording of them near the beginning of their broadcast on 15640 kHz:

Hopefully, Radio Thailand can make a similar arrangement with the USAGM.

DXing the Middle East – Then and Now

by Dan Greenall

This region consists of the western part of Asia from Turkey to Iran including the Arabian Peninsula and Egypt. Decades ago, most of the countries had a shortwave broadcasting service that made intriguing DX targets for listeners like me. Some were relatively easy to hear, while others provided more of a challenge as they did not offer broadcasts to North America (where I live) or programming was not in English. Here are a few recordings that I made over the years and have uploaded to the internet archive.

Click on titles to access Internet Archive pages with additional information.

TURKEY 1970

EGYPT 1971

ISRAEL 1971

LEBANON 1971

SYRIA 1971

JORDAN 1973

IRAQ 1971

IRAN 1971

SAUDI ARABIA 1971

UNITED ARAB EMIRATES (DUBAI) 1983

UNITED ARAB EMIRATES (ABU DHABI) 1990

QATAR 1999

As 2025 draws to a close, only a few countries from the Middle East seem to be consistently logged by the shortwave listener.

The high powered transmitters in Turkey and programming in a variety of languages provide worldwide listeners a great opportunity to tune into this part of the world. A musical interlude accompanied by frequent identifications precedes their transmission. This recording was made on July 31, 2025 at 0254 UTC leading up to 0300 sign on in English on 7275 kHz. Reception was made using a remote SDR in the UK:

The Al Dhabbiyah tramitter site in the United Arab Emirates is used by a number of international broadcasters including FEBA Radio, IBRA Media and the BBC. This recording of FEBA made on June 24, 2025 captures their sign off just prior to 0230 UTC on 9540 kHz on a KiwiSDR in Riyadh, Saudi Arabia:

IBRA Radio Ibrahim is noted using the same interval signal on June 19, 2025 around 1700 UTC also on 9540 kHz. A remote SDR in Kenya was used to make this recording.

 

Another relay transmitter is located at Al Seela in Oman and is largely used by the BBC for broadcasts into Asia. This recording, made November 20 at 2328 UTC on 11645 kHz, shows them being received by the KiwiSDR at Haida Gwaii, British Columbia off of Canada’s west coast. The effects of an over-the-pole signal path is evident here:

Other stations may emerge on occasion. For example, early in 2025, a station called Republic of Yemen Radio was being heard on 11935 kHz reportedly broadcasting in Arabic from a transmitter in Jeddah, Saudi Arabia. Reception was quite good in February using a remote SDR in Addis Ababa, however, in later months the transmitter seemed to develop a bad hum or buzz. You can listen to recordings made in February and then in April by following this link to the Internet Archive.

I would encourage all listeners to report reception of new stations broadcasting from this region to the SWLing Post so others might have the opportunity to try and tune in for themselves.
