Jungle Radio in South America – The Terry-Holden Expedition VP3THE

 
NCN Studios, Georgetown-2009

Jeff: Today, Ray Robinson takes a look at broadcasting in the South American country of Guyana, which got jump-started by an interesting American expedition into the country’s interior.  Here’s Ray with the story.

Ray:  Thanks, Jeff.  The country of Guyana is located on the north coast of South America, squeezed between Venezuela to the west, and Surinam to the east.  It is just a small tropical country, 300 miles wide and 400 miles long, with a total population of just over one million.  About 40% trace their origins back to India, 30% to Africa, and most of the rest are either indigenous or of mixed race.  Less than half of 1% are European.  The capital city is Georgetown, with a unique floating bridge, more than one mile long, over the River Demerara.

If the noted naturalist Charles Darwin had visited this area in South America, he would have discovered a multitude of unique varieties here, more than he did in his famous expedition to the Galapagos Islands during the 1830’s.  It is stated that Guyana has 4,000 plants that are not found anywhere else in the world, as well as many unique animal species, including the Golden Frog.

n ancient times, this region was inhabited by native Americans of three different tribes; the Arawak, Carib and Warrau.  Christopher Columbus was the first European visitor to the area, sailing along the coastline in 1498.  Almost a century later, the Dutch established the first European settlement, but they ceded the area to England in 1814.  The British colony of British Guiana was formally established in 1
1831.

In 1966, British Guiana gained its independence as Guyana, and four years later, this new country became a republic.  And because of its British colonial background, it’s the only country in continental South America with English as its official language.

Back in 1937, a group of six American explorers left the United States for a season of exploration in the northern jungle areas of South America on behalf of the American Museum of Natural History in New York.  This expedition, known as the Terry-Holden Expedition, arrived in Georgetown, British Guiana, and then set off up the local river systems on September 29, 1937, in flat-bottom boats for a 500-mile journey inland.

Three weeks later, the expedition established a base camp in the foothills of the Sierra Akarai Mountains near the border with Brazil.  Here, they installed a 200 watt RCA shortwave transmitter in a grass hut; this unit was allotted the callsign VP3THE, with the letters THE in the callsign identifying the Terry-Holden Expedition.

An advance party then travelled a further 200 miles on horseback, taking with them a small 50 watt Collins mobile transmitter for regular contact with the base camp.

On October 13, the expedition station VP3THE was heard for the first time in the United States, on 13900 kHz.  On this occasion, VP3THE was also in contact with amateur station VP3BG back in the capital city, Georgetown.  And it was that station, VP3BG, along with a neighboring station VP3MR, that were to grow into the first full-blown commercial broadcasting station in Guyana.

One month after the expedition station VP3THE’s first test transmission, the party began broadcasting weekly radio reports back to the United States for nationwide coverage in the NBC Red and Blue networks.  Sometimes the programs were relayed via VP3BG and VP3MR in Georgetown, and sometimes, when propagation conditions allowed, the transmission was made direct to the RCA station at Rocky Point on Long Island.

Three months after the initial test broadcast, the expedition station VP3THE left the air, never to return again.  The final broadcast was made early in the new year, on January 15, 1938.  The operator, Orison 
Hungerford, arrived back in New York three months later, during the month of April.

Two very different QSL cards were issued to verify reception reports of the Terry-Holden Expedition.  One was a duplicated plain text card with a hand drawn microphone issued by NBC in New York.  These cards were non-specific regarding the information in the QSL text.  The other card was of a large folder design, containing three photos of the station out in the jungle, and brief information about the expedition, as well as full QSL details.

So what became of VP3BG and VP3MR in Georgetown?  Well, they had come about initially some two years before the 1937 expedition, due to the demand for cricket commentary.  They broadcast on tropical band shortwave, and in 1938 were amalgamated into a single station, ZFY.  The station’s studios were in the Post Office building until it was burnt down in the Great Fire of Georgetown in February 1945.  Later that year, they moved into a new building and also secured their first medium-wave transmitter.

In 1950, the station was renamed Radio Demerara, Demerara being the name of the river that flows past Georgetown.  The station was required by its license to broadcast BBC material for 3 hours per day, and a further 90 minutes per day of other programming provided by the UK’s Central Office of Information (in London).

Here’s a sign-on of Radio Demerara in 1974 on 395 metres, 760 kHz, and I had to smile when I heard this one, because the announcer identifies himself as being “Ray Robinson”!: Audio clip available at: 

(No relation to me!)  In 1958, a second radio station was launched by Demerara's parent company, British Guiana Broadcasting Service (BGBS), with a focus on broadcasting special events and sports coverage.  Radio Demerara was on 760 kHz, and BGBS was on 560 kHz.

Two years after independence, in 1968, the government of Guyana took over the BGBS station and renamed it the Guyana Broadcasting Service (GBS).  They then built some additional studio facilities with technical aid from engineers at the BBC's Bush House in London.

In 1979, the government acquired Radio Demerara as well, and the two stations were then operated under the auspices of a new entity, the Guyana Broadcasting Corporation.  In 1980, Radio Demerara was rebranded as Channel 1, Radio Roraima, still on 760 kHz, and GBS was rebranded as Channel 2, the Voice of Guyana, on 560 kHz.  The first FM service, on 98.1 MHz, went on the air in 1998. 

In 2004, to cut costs, the radio service (Guyana Broadcasting Corporation) and the TV service (GTV), which were both operating at a loss, were combined into a single organization – the National Communications Network (NCN).

Here's a sign-on of the NCN’s Voice of Guyana from April 2017:https://www.podomatic.com/podcasts/wavescan

And that 560 kHz transmitter is still on the air today, 24 hours a day, with 7 kW from Georgetown.  For many years in Guyana, the broadcasting climate was one of nationalization and tight government control, but since the early 20-teens, a number of privately-owned low-power FM stations have been licensed, although often to organizations with close links to the government.  Curiously, Guyana is one of the few British Commonwealth countries NOT to have a local BBC World Service relay on FM.
Back to you, Jeff.



The Coming of Commercial Radio to Antigua

 


Jeff: Back in 2018 and 2021, we brought you the stories of shortwave and medium wave broadcasting from the Caribbean island of Antigua.  Ray Robinson says he struggles to remember what he had for breakfast this morning, and certainly doesn’t remember those stories, so he’s been looking at the island of Antigua again, and has put together an update with some audio clips for this week’s feature.  So, here’s Ray once again, from Los Angeles.

Ray: Thanks, Jeff.  The history of radio broadcasting from and on the Caribbean island of Antigua is an interesting one.  Antigua is actually the main island of a small country called Antigua and Barbuda, which comprises those two islands and 52 other small islands, all located at the northern end of the arc of islands that form the West Indies.

Formerly part of the UK’s Leeward Islands colony, Antigua and Barbuda gained internal autonomy in 1967, and then became fully independent from the UK in 1981.  The total population is only about 106,000, and the capital is St. John’s, on the north-west coast of Antigua. 

The first radio station of sorts on Antigua was an American Forces Radio Service (AFRS) ‘amplifier station’ which was set up during World War 2.  The United States operated two naval bases on the north coast from which they could provide protection for the Panama Canal, and the station’s purpose was to serve the military personnel on those bases.  But it wasn’t really a broadcasting station per sé.  It was a wired operation, with both relayed AFRS programming and local programming played through strategically located loudspeakers throughout the American bases.  If you’ve seen the 1970s TV series ‘M*A*S*H ’, which was set during the Korean War and depicted the same type of programming with local announcements coming through a loudspeaker on top of a tall pole, you’ll have a good mental picture of what the setup was like in Antigua.

The second station was opened by the government-owned Antigua Broadcasting Service (ABS).  This station began life as a small privately-owned 40 watt shortwave station run by aviation pioneer Sir Frank DeLisle in the early 1950’s, operating on 3255 kHz in the 90-metre tropical band with a simple center-fed doublet antenna at his home in St. John’s.  But the Antigua Broadcasting Service was officially organized in February 1956, taking over Sir Frank’s shortwave programming and equipment the following year, in 1957.  Initially they planned to upgrade the shortwave transmitter to 500 watts, but instead, in 1960, a new 500-watt medium-wave transmitter was installed on 644 kHz.  Five years later again, the medium wave frequency was adjusted to 620 kHz, to fit conventional Western Hemisphere 10 kHz channel spacing, and the station began identifying as Radio Antigua.  Subsequently, the power level was increased to 5 kW, and later again, to 10 kW.

Audio Clip - 2001 10 16 - ABS R (620kHz) - Sign On, available at:  https://www.podomatic.com/podcasts/wavescan

That was from 2001, but in 2012, ABS abandoned the use of medium wave in favor of more economical FM coverage.  Today they can be heard on 90.5 FM with 3 kW.

Then there came commercial station ZDK.  In the 1950’s and 60’s, there were only three radio stations in the Leeward Islands – the northern half of the West Indies.  These were:
• ZJB – Radio Montserrat with 1 kW on 885 kHz,
• ZIZ – St. Kitts with 5 kW on 570 kHz, and
• the aforementioned Radio Antigua,
all of which were operated on a part-time, non-commercial basis by the respective governments of those islands.

So, curious Antiguans regularly tuned in to broadcasts from farther afield, such as:
• commercial WSTA on St Thomas in the US Virgin Islands,
• WIBS, the Windward Islands Broadcasting Service on shortwave from Grenada much further south, 
• and an English-language request program called ‘Caribbean Matinee’ from station WAPA in Puerto Rico.

WSTA in St. Thomas even accommodated listeners on Antigua with a special daily program called Antigua Antics.

So, there was clearly a need for a commercial station in Antigua.  Local entrepreneur Ivor Grenville Bird saw the opportunity, and, using his middle name, set up a company called Grenville Radio Ltd.  After several applications to the local administration, Grenville was finally granted a license to operate a commercial radio broadcasting station.  The authorities didn’t think the company had the wherewithal to actually create the station, but with the help of a loan from the local branch of the Canadian Imperial Bank of Commerce, secured by some land that Bird’s father owned, they were indeed able to purchase a new 10 kW medium wave transmitter and studio equipment from the Harris Company in Illinois, USA.  A friend of a friend of Bird’s, Keith Edwards, provided a building on Temple Street in St. John’s, and also refurbished it to house the studios.  The property was then leased to the radio station at a low rent.

And thus, ZDK was launched on November 30, 1970, with 10 kW on 1100 kHz.  The company also had a 10 watt directional STL (or ‘Studio to Transmitter Link’) for ZDK on 99.0 MHz FM, to feed the signal from the studio to the transmitter on top of Boggy Peak, the highest peak on the island.  If you were in the right place, this was the first time programming could be heard in St. John’s on both the AM and FM dials.

In 1993, the station moved the studios into its own building at the corner of Bird and All Saints Roads in St, John’s.  Here’s another clip from 2001:

 Audio Clip - 2001 09 01 - ZDK (1100kHz) - Sign On, available at:  

On May 1st, 1995, a sister station to ZDK called ‘Sun FM’ was launched with 5 kW on 100.1 FM.

Audio Clip - 2004 03 28 - Sun R (100.1FM) – ID , available at: https://www.podomatic.com/podcasts/wavescan

ZDK has used various slogans over the years such as ‘The Big 11’ and ‘The Big Bad Z’, and at one stage they considered installing a 50 kW medium wave transmitter, but eventually, like the government station, they also abandoned medium wave in favor of FM, where they can now still be heard at 97.1 MHz, identifying as ZDK Liberty Radio International.

Five years after the launch of ZDK, a third medium wave station on Antigua was inaugurated as the religious Caribbean Radio Lighthouse on September 7, 1975.  This station, operated by Baptist International Missions Inc., used 10 kW initially on the split channel frequency of 1165 kHz, with studios and a transmitter site at Jolly Hill, a few miles south of St. John’s.  In 2001 they adjusted their frequency to the regular 10 kHz-spaced channel of 1160 kHz, and in 2017, their studios were rebuilt and moved about a mile to the coastal town of Valley Church.  Two FM STL’s are used by Caribbean Radio Lighthouse to send their twin programming feeds from the studios to the medium wave transmitter at Jolly Hill and also to an FM transmitter on 92.3 MHz on another nearby hill top.  The medium wave transmitter, a 10 kW Nautel unit, remains on the air to this day, and is the only medium wave station still on the air from Antigua.  It’s a great catch on 1160 kHz if you can null out KSL in Salt Lake City.

In 1976, a large new shortwave station was installed on the island of Antigua

as a joint operation by the BBC in London and Deutsche Welle in Bonn.  It was operated under the auspices of the Caribbean Relay Company Ltd., and utilized four 250 kW transmitters.  A transmission site was constructed near Seaview Farm, ironically almost in the center of the island of Antigua, and this was operational for 29 years, before being closed and dismantled in 2005.

  Audio Clip - 1981 00 00 - BBC Caribbean Relay (6195kHz) – ID available at: https://www.podomatic.com/podcasts/wavescan

But as well as operating the shortwave transmitters, the Caribbean Relay Company also transmitted the BBC World Service on 98.1 FM for the local population, including the regular regional news program, Caribbean Report.  This continued after the close of the shortwave site, and is still on the air today, although the frequency is now 89.1 FM, with 5 kW.

For about 12 years, there was also a Voice of America Relay Station on Antigua.  An agreement between the United States and the autonomous nation of Antigua and Barbuda for this station was signed in 1980.  A 17 acre site adjacent to an American Air Force Base at Coolidge on the north coast of the island was acquired, construction work began in January 1981, and the station first went on the air on April 12 of that same year.  VOA identified the location as Judge Bay.

The original equipment for VOA Antigua consisted of a 50 kW medium wave transmitter on 1580 kHz and a single omnidirectional tower.  Since power on the island could be unreliable, two 200 kVA generators provided backup power as needed.  Programming was a shortwave feed from VOA Greenville, North Carolina, which was relayed in English for four hours each night for the Eastern Caribbean.

In 1983, the station implemented a two-tower directional antenna system configured for coverage to the south.  The last entry in the WRTH for VOA Antigua was for the year 1993, seeming to indicate that the station was closed after a dozen years of service.  Like a similar VOA relay station in Costa Rica at the same time, it was closed due to budget cuts.

So today in Antigua there is the one remaining station on medium wave - Caribbean Radio Lighthouse on 1160 kHz, along with some 20 government, private commercial, and religious stations on FM, and just a single FM station on the island of Barbuda, 30 miles to the north.

Back to you, Jeff.

Highlights of Solar and Geomagnetic Activity -21 - 27 September 2026



Solar activity was at low levels throughout the summary period.
Region 4534 (N11, L=075, class/area=Dai/050 on 22 Sep) produced the
strongest flare of the period, an impulsive C3.1 flare at 26/1655
UTC. There were 13 other numbered active regions recorded on the
visible disk this week, but they all remained relatively simple and
absent of any significant activity. No Earth-directed CMEs were
observed in available coronagraph imagery. 

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 23 Sep, and 26-27 Sep due to influence from a
positive polarity CH HSS. 

Geomagnetic field activity was at quiet levels from 21-23 Sep. A CIR
ahead of a positive-polarity CH HSS caused active levels over 24-27
Sep. Total magnetic field strength reached 15 nT during the CIR on
24 Sep, with the Bz component rotating as far south as -12 nT. Solar
wind speeds steadily increased from below 300 km/s on 23 Sep to a
peak of ~525 km/s by 25 Sep. Both total magnetic field strength and
solar wind speeds gradually declined during the waning phase of the
coronal hole HSS over 26-27 Sep. 

Forecast of Solar and Geomagnetic Activity - 28 September - 24 October 2026

Solar activity is likely to continue at very low to low levels
throughout the outlook period. 

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is
expected to be at high levels from 28 Sep-03 Oct, 05 Oct-11 Oct, and
23-24 Oct due to anticipated influence from multiple, recurrent, CH
HSSs. Moderate levels are likely over the remainder of the outlook
period. 

Geomagnetic field activity is likely to reach G1 (Minor) geomagnetic
storm levels on 22 Oct. Active conditions are likely over 04-06 Oct,
21 Oct, and 23-24 Oct. Unsettled conditions are likely over 07-08
Oct and 11-14 Oct. All increases in geomagnetic activity are
associated with anticipated influence from multiple, recurrent,
coronal hole HSSs. The remainder of the outlook period is likely to
be at mostly quiet levels.

U.K. Propagation Update-25 September 2026

 


RSGB
RadCom Assistant Editor | September 25, 2026
Compiled by G0KYA, G3YLA and G4BAO on 23 September.
As we head towards the end of September, we are seeing daytime maximum usable frequencies, or MUFs, starting to climb. The daytime MUF over 3,000km is reaching 12m and is just touching 10m at times.
Within a few weeks we can expect it to reach 10m on a regular basis, perhaps bringing transatlantic QSOs to 28MHz once again.
Meanwhile, we can make the most of the openings on the 17, 15 and 12m bands, which are showing promise with increasing propagation to Asia, North Africa, South Africa and South America.
The solar flux index is hanging in there. Last week it fell to 96 but then rebounded back into the low 100s.
There are currently eight sunspot groups visible on the Sun. The good news is that geomagnetic conditions have been calm, with the Kp index mostly in the ones and twos.
That could soon change, however, thanks to a large coronal hole on the Sun’s surface.
These are dark, cool and less dense regions in the Sun’s outer atmosphere, when viewed in ultraviolet, with open magnetic field lines. This one stretches from the solar equator to its pole. There are also two coronal holes following it, which may cause more problems.
With the equinox, we often see more auroral activity due to the Earth-Sun alignment and the Russell-McPherron effect.
Once auroral conditions clear, the Kp index should return to normal, with a Kp of 2 predicted from Monday, 28 September onwards. The solar flux index may even improve slightly, with a forecast solar flux index of 115 towards the end of the month.
Make the most of the HF conditions by working one of the DX stations on the air. You can choose from 5W0AF in Samoa; JD1BON and friends on the Ogasawara Islands; OX3LX in Greenland; FR/F1TEQ and FH/F1TEQ from Reunion and Mayotte and 8Q7JH operating from the Maldives.
VHF and up propagation news:
Compiled by G3YLA and G4BAO
Recently, the overall characteristic of the weather in southern areas has been one of high pressure, giving some occasional tropo.
This region of high pressure will drift away by this weekend as a deep low over the northern Atlantic drives a weakening cold front south so any major tropo will probably not survive into the coming week.
The rest of the period looks generally unsettled.
The northern half of Britain will have the more active part of any weather system crossing the country and therefore will also have a better chance of some rain scatter on the GHz bands.
This time of the year we often experience some very active Atlantic storms. Although they may not cross the UK directly, they may be close enough for severe gales and damaging winds in northwestern areas by the middle of the coming week.
It is a good time to make sure your antenna guys are in good shape and keep an eye on the forecasts.
There are no major meteor showers in the period so, once again, any activity is likely to be random, and this is typically best in the hours just before dawn.
The prospect for auroras is a little more interesting since we are now just past the equinox of 22 September.
t is a preferential time to be alert for auroras due to the way the Earth’s magnetic field aligns better with the Sun’s magnetic field.
This makes it easier for the solar wind to get through and create auroras.
EME now, and Moon declination went positive at Moonset on Friday, 25 September. This means we will see lengthening Moon windows and higher peak Moon elevation into the coming week.
Path losses continue to fall. 144MHz sky noise starts the week low, increasing to moderate by Friday, 2 October.

Throwback Thursday-Tribute to Moosbrunn

This week's edition first aired May 6, 2001

At the beginning of this new transmission period, Adventist World Radio began a new era in its shortwave outreach with a relay via the ORF-ROI transmission facilities located near Moosbrunn in Austria.  Already, reception reports and monitoring reports from many different parts of the world indicate a nice coverage for AWR programming from this new relay site.

In honor of the new relay arrangement between AWR and ORF-ROI, we present in this edition of Wavescan a "Tribute to Moosbrunn."

The atlas tells us that the town of Moosbrunn is located about 12 miles southeast of Vienna on the edge of the famed Vienna Woods, as immortalized in the beautiful music from Johann Strauss.  The dictionary tells us that the word "Moosbrunn" means "Mossy Well."

Actually, Austria lays claim to the first broadcast of the human voice.  Professor Otto Nussbaumer invented a wireless "detector circuit," and as a demonstration he yodelled an Austrian folk tune into his equipment and it was received on similar equipment in the next room.  This was in the year 1901.

The first wireless communication stations in Austria were erected in country areas beginning around 1915, and the first radio broadcasting station went on the air in Vienna on October 1, 1924.  The studio was located in a government building, the transmitter was a 700 watt Telefunken unit, the channel was 530 metres (565 kHz), and the callsign was ORV.

On the shortwave scene, the first broadcasts from Austria went on the air in 1926 under the callsign OHK2 from a 300 watt transmitter located at Rosenhuegel near Vienna.  The channel for these test broadcasts was 6075 kHz, and the programming was a relay from the mediumwave Home Service. 

In 1931 under new radio regulations, the callsign was changed from OHK2 to UOR2, and later again to OER2.  By this time the power output had been increased to 2 kw.

Around this same time, a mobile shortwave station was launched under the callsign EATH.  This station was on the air for just four hours each week, with local news reports and commentaries. 

Now we come to the Moosbrunn era.  This large property was procured in 1959, and the first transmitters on the air from this location were units taken from submarines.  Several of these units, installed in a temporary wooden building, were linked together to give a total output of 100 kw. 

When the new and permanent transmitter building was completed, four Telefunken units at 100 kw were installed progressively.  The large antenna farm contained a variety of antennas:  rhombics, curtains, a vertical incidence array, and a rotatable log periodic with reflector.

Currently, ORF-ROI maintains a complement of six shortwave transmitters at Moosbrunn, four at 100 kw and two at 500 kw.  Two of the 100 kw units are in regular use, and two are available for backup service.  The two units rated at 500 kw are on the air at 300 kw due to antenna constraints.

The new AWR relay service from Moosbrunn is on the air over the two larger transmitters.  One is in use 12 hours daily to Africa and the Middle East, and the other for a few hours daily to Europe.

On the occasion of this significant new development in international radio co-operation, Adventist World Radio honors Radio Austria International in appreciation for this new relay service.

Highlights of Solar and Geomagnetic Activity 14 - 20 September 2026


Solar activity was at very low levels on 14-18 Sep and increased to
low levels on 19-20 Sep. Region 4535 (N12, L=353, class/area Hrx/020
on 20 Sep) produced a C1.1 flare at 20/0518 UTC, while Region 4534
(N11, L=074, class/area Dro/030 on 20 Sep) produced a C3.7/1f flare
at 20/2234 UTC, the largest of the period. No Earth-directed CMEs
were detected during the highlight period. 



No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at
high levels on 14 Sep when a maximum flux of 4,650 pfu was observed
at 14/1315 UTC. Low to moderate levels were observed on 15-20 Sep. 

Geomagnetic field activity reached unsettled levels on 14-17 Sep,
with isolated active levels observed on 14 and 16 Sep. Unsettled to
active levels were observed on 14 Sep due to a southern hemisphere
filament eruption coupled with a SSBC. Unsettled levels were
observed on 15-17 Sep, with an isolated active period early on 16
Sep, all due to negative polarity CH HSS effects. Quiet to isolated
unsettled levels were observed on 18-20 Sep. 

Forecast of Solar and Geomagnetic Activity 21 September - 17 October 2026
