The Radio History of Goa, India

 

Special thanks to Ray Robinson and Jeff White for sharing the interesting story on broadcasting from Goa.

Jeff: When our Editor-in-Chief, Dr. Adrian Peterson, was based at AWR Asia in Pune, India, he became quite familiar with the former Portuguese enclave of Goa on the west coast of India, about 200 miles to the south. He says it’s a fascinating place to visit, with miles of wide ocean beaches, varied coastal and inland scenery, and tropical and sub-tropical fruits.  To this day, Goa still exudes a subtle evidence of its earlier European culture, with Latin style church architecture, European style of dress, Portuguese Konkani music, and the occasional usage of the Portuguese language. Adrian visited Goa on many occasions and has jogged its entire 65 mile coastline. Here’s Ray Robinson in Los Angeles with the interesting story of how radio broadcasting developed in that unusual territory.

Ray: Thanks, Jeff. Goa is now the smallest Indian state, located about halfway down the west coast of the sub-continent. It has a total land area of just 1500 square miles – about one and half times the size of the U.S. state of Rhode Island. Portugal first colonized the area in 1498, when Vasco da Gama reached nearby Calicut on the Malabar coast, and over the ensuing years, more than 20 small Portuguese colonies were established, of which Goa was the largest and most important. 

During the 2 nd World War, Portugal remained neutral, and thus Goa also was a neutral territory, surrounded by British India. (What could possibly go wrong, right?) Well, during the war, three German trading vessels took shelter in the harbor at Mormugao. Then in 1943, one of them was sunk by British forces because it was determined that a radio transmitter on board the vessel was alerting German submarines lurking nearby to the movement of British shipping.

India gained independence from the United Kingdom after the war in 1947, and after the new constitution was adopted in January 1950 establishing the Republic of India, representations were made to the Portuguese government about releasing their colonies on the subcontinent also, in order for them to be incorporated into the Indian Union. Several requests were made throughout the 1950’s, but all were rebuffed by Lisbon.

It was during the post-war period that the first radio broadcasting stations were set up in Goa. Cable communication had been established between Goa and Portugal as early as 1938, via Cable & Wireless in Bombay. Eight years later in 1946, the resident engineer for the cable company in Goa, Victor Carvalho, gave technical assistance to a newly formed Radio Clube, and a new private radio broadcasting service was instituted with the use of a small amateur transmitter donated by Jose Ferreira. Across the water in Lourenço Marques in Portuguese Mozambique, another Radio Clube had been established in 1935 – Radio Clube de Mozambique, with the primary purpose of broadcasting in English to South Africa. But this Radio Clube, in Goa, mostly broadcast in Portuguese and the local
Konkani language.

The date of the first radio transmission from this new station was May 28, 1946, and the territorial Governor-General issued a postage stamp on the same day to commemorate the event. It’s said that the first improvised microphone was encased in a coconut shell. (I wonder if that improved the acoustics?) Two years later, in 1948, a more substantial radio broadcasting station was erected with the studios and transmitter co-sited on the rise of a hill at Altinho overlooking the capital city, which under the Portuguese administration was called Panjim. The name for this new service was Emissora de Goa. The transmitter was a 500 watt shortwave unit manufactured by the American Federal Telephone & Radio Corporation of Clifton, New Jersey in the United States, and it was fed into a locally-
made power amplifier which raised the output power to the aerial to 1 kW.

The original channel was 7230 kHz in the 41 meter band, though soon afterwards, the operating frequency was moved to the more familiar 9610 kHz in the 31 meter band. This station was widely reported in several countries of Europe, as well as in the United States and the South Pacific, and numerous QSL letters and cards were issued in confirmation of listener reception reports. In 1950, a medium wave transmitter was installed at the studio location and this operated with 2.5 kW on 557 kHz. At that stage also, regular callsigns were introduced and assigned to this radio broadcasting service by the authorities in Lisbon. The call for the medium wave outlet was listed as CR8AA, and the  shortwave outlet was identified as CR8AB. You may recall that Radio Clube de Moçambique had previously been assigned CR7AA, so these new call signs were presumably the next in the series.

In 1952, four years after the station was launched at Altinho, a second transmitter site was constructed three miles south at a more rural location known as Bambolim. The first transmitter installed there was a shortwave unit rated at 7.5 kW. Seven years later, a 10 kW shortwave transmitter was also installed at this location, as well as two medium wave transmitters rated at 5 and 10 kW. While programming on Emissora de Goa was mainly in Portuguese, there was at least one English program, because the Seventh Day Adventist church began a regular series of broadcasts on this station – their first in Asia. The program was the "Voice of Prophecy", recorded by the illustrious Dr. H. M. S. Richards in California. 

Programs were supplied on large 18 inch discs, and they were on the air each
Sunday for half an hour. "Voice of Prophecy" was the first syndicated Christian religious broadcast from Emissora de Goa, and it was carried by CR8AA with 2.5 kW on 557 kHz, and CR8AB with 1 kW on 9610 kHz. The first broadcast of this program took place on Sunday, April 30, 1950, and it was on the air for coverage into India on and off throughout the period from 1950-1954. After that, the broadcasts were switched to the Commercial Service of Radio Ceylon in Colombo.

But, trouble was brewing for Portuguese Goa, and on Monday December 18, 1961, Emissora de Goa left the air abruptly at 8:00 am. Tired of being rebuffed by Portugal, the Indian government launched an air force bombing raid against Goa. The station at Bambolim was attacked, and an aerial photograph shows the whole facility burning furiously. Goa was taken over the next day, Tuesday December 19, 1961, and the process began to annex the territory and absorb it into the independent nation of India. At the time of the takeover, Emissora de Goa had been on the air with a total of six transmitters – 1 MW and 2 FM at the original Altinho site, and another MW plus 2 SW at Bambolim. 

The small capital city of Panjim was then renamed Panaji in the local Konkani language. Work commenced immediately on the restoration of the radio broadcasting stations. No damage had been done to the studio facility at Altinho, though at least one of the transmitter buildings at Bambolim had suffered a massive fire.

Amazingly, just three weeks later, at 6:00 pm on Wednesday, January 10, 1962, Emissora de Goa was reactivated under All India Radio using a temporary low-power transmitter on 880 kHz. A speech was broadcast from the new military governor, Major General K. P. Candeth. Curiously, the station slogan, remained in use as the local identification announcement for more than another four years. Then, on October 12, 1966, the Portuguese "Emissora" identification was finally dropped, and the station announcement was changed to All India Radio, Panaji.

Eventually, the 50 kW shortwave transmitter at Bambolim was reactivated for the broadcast of the General Overseas Service of All India Radio in the Konkani language, beamed towards Africa. This service was on the air at 1815 UTC on 11780 kHz and the programming included news, folk dramas, request songs, and other feature programs. External Service programming in the Konkani language had been on the air previously from this transmitter under Emissora de Goa, and it would appear that the revived Konkani programming was indeed coming from Goa itself. On May 22, 1969, a new 10 kW medium wave transmitter tuned to 880 kHz was inaugurated at Bambolim; and since then, additional medium wave, FM and TV transmitters were installed in Goa, but not for any revived local shortwave service.

The studio building was renovated and enlarged, and then more recently, new studio buildings were erected. In 1992, All India Radio built a large high-powered shortwave station for General Overseas Service programming at Bambolim, adjacent to the old transmitter facilityof Emissora de Goa. Two 250 kW transmitters and a new antenna farm were installed, to facilitate broadcasts to foreign countries to the northwest, northeast and southeast. 

The first test transmissions were heard in November 1994 on 4775 kHz, and by February 1995 the transmitters were on a regular schedule, which included the relay of programming from the local medium wave station in Panaji which by then was on 1287 kHz.

On Adrian Peterson’s last visit to Goa some years ago, he found that the studios and offices on the hill overlooking Panaji had been rebuilt twice and were in use by All India Radio, now Akashvani.  The newer shortwave base at Bambolim with two 250 kW transmitters was at that time still being used for the AIR General Overseas Service.  But all that was left of the old Emissora de Goa transmitter buildings was some wreckage, completely overgrown by grass and other vegetation.

The 2024 World Radio TV Handbook does still show two medium wave transmitters on the air in Goa, the Akashvani Vividh Bharati channel with 20 kW on 828 kHz, and Akashvani’s ‘Panaji A’ service with 100 kW on 1287 kHz, in both analog and DRM modes. The latter is also carried in parallel with 10 kW on 101.1 FM, along with a ‘Panaji B’ service with 6 kW on 105.4 FM. Private FM stations listed in Goa currently include:
Radio Indigo on 91.9, and
Big FM on 92.7.
There are no longer any shortwave transmitters in Goa, nor any External Service broadcasts in the Konkani language.
Back to you, Jeff.

Yesterday had a faint hint that another station might be here besides the usual Beibu Bay Radio, so monitored this frequency again today, at 1120-1127. Prominent test tone, went off for a minute until start of the distinctive AIR interval signal.

Possible news 1130-1145 in Hindi, then at 1135 noted "this is All India Radio with the news read by . ." Items not very readable due to Beibu Bay Radio interference.

India’s 100,000 Islands: The Radio Scene on Kavaratti Island


6. Kavaratti: Following on from our previous topic on the Lakshadweep islands a few weeks back, we come now to the story about the mediumwave radio station on Kavaratti Island.

The Lakshadweep Islands are the northernmost cluster of islands in West Aquamontia in the Arabian Sea off the west coast of India.  Actually, Kavaratti Island is the capital “city” island in Lakshadweep, though it is not quite the largest island in the archipelago.

Androth Island is slightly larger than Kavaratti, with just a few more people.  Kavaratti has an area of just 1.52 square miles, and a population a little in excess of 11,000 according to at least one authority.
The island has 190 ponds to collect fresh water from the annual monsoon rains, and an additional 1325 fresh water wells.  In addition, the Indian government has installed a desalination plant on the island that is able to obtain 26,000 gallons of drinking water from the ocean each day.

The National Institute of Amateur Radio NIAR in Hyderabad has sent several amateur radio personnel on DXpeditions to the Lakshadweep Islands and Jose Jacob VU2JOS has himself participated in three of these DXpeditions.  Jose states that on the occasion of his first visit to Kavaratti in 1989, they operated under the callsign VU7APR on Kavaratti Island, and under the callsign  VU7NRO on nearby Kadmat Island.

There was no mediumwave station on the island back then. However, a high powered mediumwave station across the waters at Kozhikode on the Malibar Coast of South India with 100 kW on 684 kHz provided evening programming for the benefit of listeners in the Lakshdweep Islands.

There was a longwave radio beacon on the island for use in local navigation by planes and ships. In addition, there were already two solar powered 10 watt TV relay stations on the air.  However, most of the residents throughout Lakshadweep prefer to watch TV via the satellite delivered cable systems.

Work on a new mediumwave station for Kavaratti began in 1993 at a location in the middle of the island.  This new AIR All India Radio station with 1 kW on 1584 kHz was inaugurated on January 1 of the following year (1994) following a series of test transmissions. Quite by chance, Jose Jacob happened to hear this station on its first day of broadcast, though it took another 9 years before he finally received a QSL letter verifying his reception of this unique island radio station.

Eighteen years after the 1 kW mediumwave transmitter was inaugurated, a new 10 kW transmitter was installed at the same location, a Thompson analog/digital unit Model M2W.  When this new transmitter was taken into service on April 21, 2016 on 1152 kHz, the old 1 kW transmitter was retired.  However, consideration has been given on occasions to utilizing the old low power transmitter for local community programming.

An FM station with 100 watts on 100.1 MHz began to carry a slave relay of mediumwave programming on December 14, 2012. The AIR station on Kavaratti takes most of its programming as a relay from the AIR headquarters station in the state capital Trivandrum, with a few hours each day of locally produced programming.  Jose Jacob also informs us that a 10 minute daily program from the Pune studios of Adventist World Radio is heard via the FM transmitters on Kavaratti, and via the mediumwave transmitter on 1152 kHz.

On a previous occasion here in Wavescan, we presented information regarding five islands in Lakshadweep and for the next few minutes, we catch a brief glimpse of the radio scene on several of the remaining islands in this archipelago.
7. Chetlat is a small island of less than half a square mile and a population of a little more than 2,000. A local solar powered TV station has been on the air here for the past several years.

8. Kadmat also has a local low power TV station that presents a continuous relay of mainland Indian programming. This island of one and a quarter square miles has a population of around 3,500 people. In 2006, two officials from the National Institute of Amateur Radio, Ram Mohan VU2MYH and Jose Jacob VU2JOS, made a fact finding visit to Kadmat Island. Subsequently, two amateur DXpeditions have operated from Kadmat, and they were on the air consecutively as VU7RG and VU7NRO. 

9. Kalpatti is a very small uninhabited island and it is the westernmost territory of India.  Some years ago it was under consideration for use as an extension to the airport runway from nearby Agatti Island, though this project was never implemented due to wild life conservation. Jose Jacob also visited this island as an assessment project.

10. Kalpeni has a population in excess of four thousand on its one square mile. This island also has a low power TV relay station, and one NIAR amateur radio DXpedition has been staged there.

11. Kiltan supports a population of 3,600 on its .85 square miles of island territory.  This island also operates a low power over the air solar powered TV station.

A Fire Destroyed a Shortwave Station in India


Quite recently, Gautam Kumar Sharma of Abhayapuri in the northeast Indian state of Assam emailed us with two interesting radio stories. 

One story was about a Royal Bengal Tiger that prowled through the estate of All India Radio in Tezpur Assam, and the other was the story of a fire at All India Radio Itanagar.  Two weeks back we presented the Tiger story in Assam here in Wavescan, and on this occasion, we present the story of the fire in the AIR transmitter facility at Itanagar in the nearby state of Arunachal Pradesh.

The small state of Arunachal Pradesh is the most northeasterly state in the Union of India and it is a relatively new state, having been designated as such in 1987. Originally Arunachal Pradesh was administered as part of the larger state of Assam.

The state name Arunachal Pradesh means the Land of the Morning Mountains and it is home to many tribal peoples who speak some 50 languages and dialects, though English is the only official language.  It is home to a plethora of some 500 different species of bird life, and a variety of butterflies, medicinal plants and wild animals such as elephants, deer, leopards and monkeys.

This distant state is the largest of the now 8 sister states in the North East with an area of 33,000 square miles and a population of 1.3 million.  Their capital city is Itanagar with a population of 60,000.  The city name, Itanagar, means Brick Village, having reference to a major local industry.

Over a period of time, five different medium wave stations have been installed throughout the territory that became the state of Arunachal Pradesh.  The first two stations were installed in the mid 1960s at Passighat and Tezu in the north of the state, and though listed with 1 kW each, they were on the air back then with only one tenth of that power value. 

These days, the Passighat station operates with high power 100 kW on 1072 kHz, and Tezu with medium power 10 kW on 1332 kHz.

The Tawang station was installed a decade later at a power level of just 500 watts, and the Ziro station with 1 kW was installed around the turn of the century.  These two towns are located towards the western end of the state.  These days Tawang operates with 20 kW on 1521 kHz and Ziro operates with still just 1 kW on 1702 kHz.

The AIR station in the capital city Itanagar was installed in the mid 1980's with 1 kW on 675 kHz. Then on February 5, 1996, a new superpower 100 kW medium wave transmitter was inaugurated though still on the same channel 675 kHz.

Their 50 kW shortwave station was installed in the early 1990s with a power of 50 kW.  The test broadcasts were noted internationally on four different shortwave channels. However, around ten years into the new millennium, and the station was noted off the air more than on, due to technical problems. 

On August 20, 2015, work commenced at the already established medium wave and shortwave transmitter facility at Khating Hills near Itanagar for the installation of a superpower 200 kW analog/digital medium wave transmitter. 

Next month, at 5:30 am on Friday morning September 25, smoke was observed coming from the building. Two fire engines attempted to quench the flames, with little success, and all of the transmitters, both medium wave and shortwave, were completely destroyed.  In fact, all major electronic equipment in seven rooms at the transmitter site was badly damaged. 

As an emergency measure, all programming from the city studios was broadcast on their only other channel, their FM outlet 103.1 MHz.  The cause of the disastrous fire was eventually acknowledged to be an electrical short circuit. 

These days, All India Radio Itanagar is heard on the air from their new analog/digital transmitter with 100 kW on 675 kHz, and also running  200 kW DRM on the adjacent channel 684 kHz as well as on several FM outlets.  Their shortwave service has never been revived.

New Chronohertz Station in India

A news item in the April issue of the Australian DX News informs us that India is planning to construct a new chronohertz station with two towers that will stand three times higher than the Qutab Minar in Delhi.  The height of the Qutab Minar is listed at 240 feet, which would mean that the new radio towers would stand at around 720 feet, the tallest self standing towers in India.

The Qutab Minar is a famous ancient landmark in New Delhi nearly two thousand years old.  It is constructed from ornately carved red sandstone and marble, with an internal staircase of 379 steps.  The design of the Qutab Minar in India is described as basically Persian in style, though it was patterned after the Minaret of Jam in a remote area of western Afghanistan.

The location for this new longwave radio station in India has not yet been chosen, though it will be a function of NPL, the National Physical Laboratory.  Interestingly, NPL did operate a chronohertz shortwave station many years ago, and its standard time and frequency signals were heard on three shortwave channels, 5 10 and 15 MHz.

In our program today, we go back and take a historic look at the earlier station ATA, the old chronohertz station in India; and just as a matter of interest, we begin with the measurement of time, as it was in the ancient eras of antiquity.

It was way back more than four thousand years ago that people in the old middle eastern world were measuring time with what we would call today, shadow clocks.  That is, as the shadow from a fixed object moved as the sun appeared to move, then an approximate calculation of local time could be gauged.

According to current historians, the first known specific reference to a sun dial, that is, in the old concept of how they were made, is found in the Bible.  It is stated that King Hezekiah was familiar with the progress of the day with a sun dial that his father KIng Ahaz had constructed, and that was way back around 700 BC. 

This sun dial was a function of the palace structure in his capital city, Jerusalem, and it was probably a building somewhat similar to that which was built in India three hundred years ago, not a small brass plate with a projecting gnomon like we use today.

A QSL card issued by All India Radio in New Delhi back in the 1980s shows a picture of a
similar structure known as Jantar Mantar).  This structure, located on Parliament Street quite close to the long time headquarters of All India Radio, was constructed by Maharajah Sawai Jai Singh of Jaipur in the year 1724, though some historians had mistakenly given an incorrect date a few years earlier. 

A cluster of buildings at Jantar Mantar in Delhi, large and small, was designed in such a way that the time of day, right down to a second, could be accurately measured from the shadow of the sun as it moved across one of the buildings.  All of the fourteen geometric structures at this location were designed to accurately predict the movement of planets and stars, as well as to predict eclipses of the sun and moon.

However, as time went by, other methods of measuring time more accurately were needed.  It was back in the year 1368 that the first public clock was made in England, and it was more than a
century later that the first domestic clock was made in Germany.  The first watch was made in the year 1510.

In our more recent electronic era, more accurate methods of time keeping are required, and it was in 1937 that the American chronohertz station, WWV in Washington DC, began to broadcast time signals.  It was in 1955 that the atomic clock was invented in England.

Now, back to the story of the Indian radio station ATA.  Just one year after the infinitely accurate atomic clock was developed in England, plans were formulated to establish a chronohertz station for India, based on a concept similar to the American station WWV. 

Three years later, the new ATA was inaugurated at the National Physical Laboratory on Hillside Road, Kalkaji, New Delhi on February 4, 1959.  A Westinghouse transmitter began a temporary experimental service with 2 kW on exactly 10 MHz, using a horizontal dipole antenna at the height of one wavelength.

However as time would tell, another sixteen years passed by before another transmitter was installed.  This was a 5 kW unit that was rated at 10 kW PEP, and this took over the broadcast service on 10 MHz on August 1, 1975.  This new shortwave transmitter that replaced the original 2 kW
Westinghouse unit, was made by Marconi in England.

The third transmitter at station ATA, another 5/10 kW unit, also built by Marconi in England, was inaugurated almost a year later.  The schedule for this transmitter was night time on 5 MHz and day time on 15 MHz.

Way back then, there was a nice co-operation between the old DX program from Adventist World Radio in Asia, Radio Monitors International, and the chronohertz station ATA.  Each year in the RMI DX program, an ATA Day was conducted to commemorate the service rendered to the radio world by ATA.  In addition, a QSL card was designed for ATA in the AWR office in Poona, and changes and
developments at ATA were announced over the air in the AWR DX program.

However, as Jose Jacob, VU2JOS at the National Institute of Amateur Radio in Hyderabad tells us, station ATA left the air some time around the year 2000, due to ailing equipment.  The time signal and frequency service was transferred from radio to satellite and also to the telephone system.

During its more than 40 years of on air service, station ATA utilized just three shortwave
transmitters, not four, as previously thought.  The original 2 kW Westinghouse unit was on the air from 1959 to 1975; and the two subsequent Marconi units were inaugurated in 1975 & 1976.  These
shortwave transmitters were all withdrawn from service in the year 2000.

Initially, QSL letters and prepared QSL cards were issued during the first era of on air activity from station ATA.  Subsequently, just one batch of QSL cards was printed for ATA usage, and these were in black print on yellow card. 

And now, it seems that chronohertz station ATA may be back on the air again one day, perhaps under a different callsign, and this time not on shortwave but rather on longwave from two tall towers.

Interestingly, the callsign ATA has at times been in use also from other radio stations in India.  For example, the callsign ATA was in use on shortwave by the meteorological station in Delhi with weather information.  Then too, the amateur callsign prefix in use for the Indian Antarctic Expedition some years ago was also ATA.

Early Wireless Stations in India

Research into the early usage of wireless communication in Morse code indicates that India was one of the very first countries in the world to establish wireless stations for the practical conveyance of important messages.  The first cluster of these early wireless stations in India was installed on the eastern edge of the Indian sub-continent in what is now the state of West Bengal, and the era was way back during the very early 1900s.
Saugo Island Lighthouse
            Saugo Island is a large mainly silt island that lies at the eastern edge of the Hooghly River in the delta areas south of the massive city of Calcutta-Kolkata.  During the past 40 years or more, something like half of the island has been washed away, due to storms and rising ocean levels.

            As a matter of interest, the Saugor Island Lighthouse became famous in 1934 when a rocket containing special postal mail exploded overhead.  Most of the scattered items of postal mail were recovered, and the lighthouse keeper postmarked them in the lighthouse.

             But, back to the wireless scene . . . what would now be described as a primitive spark wireless station was installed on Saugor Island in 1902.  It would be suggested that this new wireless station was installed at the lighthouse on Saugor Island. The antenna system was attached to a mast standing 120 feet tall.

             Two way communication in Morse code was achieved between Saugor Island and another equally primitive wireless station that was installed on a government control ship, the Eastern Channel Lightship, in 1902.  This ship was stationed further out into the Bay of Bengal at Sandheads, a cluster of low mainly silt islands near which was the gathering point for incoming shipping. 

            These ships were awaiting the small pilot vessel to take them one by one into the wharves at the city of Calcutta.  Initially, the wireless call sign on board the Lightship was ROS, though subsequently the call was changed to VWS. 

            Two years later (1904), new and upgraded equipment was installed on Saugor Island; and additionally, a new set of equipment was also installed on a newly built pilot vessel that had just been obtained from England, the Fraser.

            Give a few more years, and another wireless station was installed at Diamond Harbour in the waterways of Calcutta itself.  This station was moved soon afterwards to nearby Budge Budge, and subsequently again, to Calcutta South.  

            The original call sign of this Calcutta station was ROC, though soon afterwards it became WCA.  However, another change of call sign provided what has since become a permanent call sign for the maritime communication station in the Calcutta-Kolkata area, the now well known VWC.  This station is still on the air to this day, with weather information, time signals, and shipping communication.

            In August 1904, another set of three wireless stations was installed across the other side of the Bay of Bengal.  These three stations were installed at Diamond Island in Burma-Myanmar;Table Island in the Andamans; and Port Blair, also in the Andamans.

            The key station in this threesome was located on Diamond Island, Burma which is not to be confused with Diamond Harbour in Calcutta.  This Burmese station was installed on Diamond Island which is located at the delta mouths of the Irrawaddy River, and it was intended for communication with Port Blair in the Andaman Islands.

            The original 1904 transmitter on Diamond Island was rated, strange as it may seem to us today, at ½ hp horse power, though in March of the following year (1905) a 3 hp transmitter was installed.  The original calls ign for the Diamond Island wireless station was ROD, and this was changed to VTD around the time when World War 1 began (1914).

            Initially, the location for the destination wireless station in this threesome was intended to be Ross Island, just three miles east of Port Blair on South Andaman Island.  At the time, the British administration of the Andaman Islands was located on Ross Island.

            However, an assessment study demonstrated that there was no suitable location for the wireless antenna system on small Ross Island, so the project was transferred to the “mainland” on South Andaman Island.  The actual location for the Port Blair wireless station was at Aberdeen, immediately north of the women’s prison.

            Initially, the wireless equipment was installed temporarily in a small cluster of tents.  The first transmitter for Port Blair was rated at ½ hp, and the allotted call sign was ROP.  During a series of test transmissions on November 1, 1904, station ROP was heard clearly with a set of similar equipment aboard the ship Minto in Port Blair Harbour.  Nearly 8 weeks later on December 22 (1904), direct communication was achieved between stations ROP Port Blair and ROD Diamond Island.

            In January (1905), construction work was completed on the brick buildings for the wireless station at Port Blair and the electrical equipment was transferred from the tents into the new substantial facility.  In March (1905), a new 3 hp transmitter was also installed here at Port Blair.  The Port Blair call sign was also changed around the time when World War began (1914) and ROP became VTP. 

            Back during that same era, an intermediate relay station between ROD Diamond Island and ROP Port Blair was installed on a small island in the lengthy chain of islands that run down south from the Irrawaddy delta in Myanmar to Sumatra in Indonesia.  Generally speaking, the intermediate relay station was identified as Table Island, though in reality it was installed on the much smaller Slipper Island.  

            Strangely, there are two small islands in this same chain of islands that are identified on the map as Table Island; and back then, the location for each was given as the Andaman Islands.  One Table Island is located just off the east coast of North Andaman Island.  This Table Island is a mile long; it is less than a quarter mile wide; it is shaped like the Australian boomerang; it has never been inhabited; and there never was a historic wireless station on that island.

            The other Table Island is in the Coco Islands belonging to Burma, not in the Andaman Islands belonging to India.  However back then, all of the islands in the chain of islands running down south from the Irrawaddy delta in Burma/Myanmar towards the island of Sumatra in Indonesia were known as the Andamans.  And in addition, during the earlier colonial era, Burma itself was administered as part of British India.    

            This Table Island is an irregularly shaped island that is situated a little north of Great Coco Island.  An iron lighthouse was installed on the southwest edge of Table Island in 1867, and it can still be seen on Google Earth to this day.

            Slipper Island is a very small island to the west of Table Island and it is connected by a sand bar that is above water level at low tide. On November 30, 1904, a small party of wireless personnel arrived at this Table Island in order to choose a suitable location for the intermediate wireless relay station.  However, they chose Slipper Island instead because it was as far west as possible.

            On January 11 of the next year (1905), installation of the new wireless station, the ½ hp transmitter under the call sign ROI, was completed, and next day Morse Code communication was made with station ROD Diamond Island.  Three weeks later on January 30 (1905), all three stations achieved satisfactory intercommunication in Morse Code: ROD Diamond Island, ROI Slipper Island, and ROP Port Blair. 

            As with Diamond Island and Port Blair, a new 3 hp transmitter was installed on Slipper Island in March (1905), and Slipper Island was given a new call sign in 1914; ROI became VTT.

            That was the story of the wireless stations in East India during the era before World War 1.  When the war began (August 1914) there were 5 wireless stations in two different networks in regular service in the Bay of Bengal area:-  

1. VWC Calcutta, VWS Sandheads
2. VTD Diamond Island, VTT Slipper-Table Island (Andamans), VTP Port Blair
