Caribbean Aircraft Handling – ICOM IC-A110E with a remote control

CaribbeanAircraftHandling_TruckCaribbean Aircraft Handling is one of the largest ground handling companies at the Grantley Adams International Airport. We have supplied their operation with radio communication for many years.

Recently they moved their operations office to a new building on the ramp to be closer to the aircraft. This building is one of the first things an arriving passenger would see. We could not put the antenna on the roof! The ICOM IC-A110E, which was used to communicate to the aircraft, was to be installed in the communication building some 500 meters away and controlled remotely from the ramp office.

At first we considered using a Radio Over Internet Protocol (ROIP) to do this. This option was quickly discarded due to the high cost.

Mobile & Marine Systems Ltd designed a simple analogue system using 4-wire 600-Ohm connection. Both locations already had ample copper pairs and it was an easy job to link them together in the main distribution room. A two wire link could have been used but we choose to go with a 4-wire to minimize the possibility of cross talk.

Once this was done and tested we attached an ICOM OPC-871 Aviation headset adapter to the ICOM A110E. This is normally used to connect the radio to a Dick Clarke headset. We modified the jacks to ¼ inch size. These were used to connect the radio to a CPI Communications Inc. TTP1 Remote controller. Using in-band signaling the CPI TR10 remote in the operations office is able to monitor and talk to the aircraft 50Km or more out. This is especially important to ensure a quick turnaround once the aircraft has landed.

We have used CPI remote products for many years both as DC remote controllers and Tone remotes. This is the first time we have used it in an Air to Ground setup. Once installed the system has been 100% reliable.

Moving to digital radio using Icom Radio Systems

icom_LogoICOM has developed a line of Digital 2-way radio products and systems that meet the demands of today’s business user.

Mobile & Marine Systems Ltd. uses this technology to enable our customers to migrate to a DIGITAL network without having to scrap their existing analogue radios.

The ICOM FR5100 repeater can operate in both Analogue and DIGITAL modes. This enables the customer to use both technologies on one repeater making a considerable saving on the cost of upgrading.

Mobile & Marine Systems Ltd. has installed several systems for customers who want the advanced features that ICOM IDAS offer.

A security company that specializes in the transfer of cash, and security at private residences required a secure and reliable upgrade to their present system. Mobile & Marine Systems Ltd. replaced their existing repeater system with an ICOM FR5100 Repeater system and supplied ICOM F3162 and F5062 Digital radios.

One of the embassies in Barbados required a state of the art system for their security network. Again Mobile & Marine Systems Ltd provided an ICOM IDAS network. This enabled the security officers to have clear and confidential communication across the island.

A large West Coast House needed a secure system to be used by the management as well as security when the owners were in residence. ICOM IDAS was able to tick all of the boxes required by the client.

Grantley Adams International Airport uses an ICOM FR5100 Repeater operating in both Digital and Analogue modes for the airport security and engineering departments.

Some of the features and benefits of upgrading to IDAS digital are:-

  • Privacy – with Digital network a scanner cannot monitor the conversations. ICOM IDAS comes with Digital encryption with over 1000 different codes. This further improves the security.
  • Clearer Communications – with the Digital encoder the voice is much clearer and audible that with traditional analogue technology.
  • Kill and Stun – can quickly disable a radio that is lost so that the integrity of the system is kept.
  • Remote monitor – enables the base station to monitor a handheld without the operator being aware.
  • Emergency Mode – if a guard needs urgent help he can activate the emergency mode and his radio will send a digital signal to other radios advising them of the situation as well as the radio number.

These are just a few of the many features that can be selected in the setup and programming of the system.  For a full list of the features of the ICOM IDAS systems visit  www.icomuk.co.uk

BGI, Grantley Adams Airport – Barbados

Tait MPT 1327 at Grantley Adams International Airport (BGI).

BGI_GrantleyAdamsAirportRoadsideBGI_GrantleyAdamsArptnasaBGI_Check-inBGI_Concord_BarbadosMobile & Marine Systems Ltd. operates a Tait MPT-1327 system in Barbados. This 3 site UHF system provides a cost effective solution for mobile communication. In addition to the standard trunk features customers are pleased with the ability to be able to call individual units in their fleet without their company business being broadcast over the entire fleet. This increases the level of confidentiality for the users.

This Tait Trunked system has proved to be very popular with the users and management at the Grantley Adams International Airport and has considerably improved the efficiency of airport operations.  It has proved very popular with the airline and service providers at the airport who until this new Tait MPT 1327 system was installed found it difficult for the check-in counters to communicate with the gates.

The Tait MPT-1327 trunk system makes it possible for Mobile & Marine Systems Ltd. to use their spectrum allocation more efficiently.

The Grantley Adams International Airport (BGI) is the international gate way for Barbados and is a hub for several airlines servicing the islands of the Eastern Caribbean.  Every year 2.4 million passengers use the facility. The airport also handles air-sea transfers for passengers destined for the numerous cruise ships that sail the Caribbean Sea.  The Grantley Adams International Airport is also home to one of the Concorde aircraft.  When this aircraft was in service it made weekly flights from London to Barbados.

Until recently each airline used a mix UHF and VHF hand portable radios.  With no repeater service it was difficult for the check-in counter to communicate with the gates.  Calls had to be manually relayed by the base. Installing a base station was very expensive as running the antenna feeder to the roof was a major undertaking. There were also no radio communication between the various agencies operating at the Airport.

A new terminal is being built to meet the passenger needs for the next 15 years.  As this project entailed the renovation of the existing terminal and the construction of a new terminal for arrivals there was a lot of dislocation during construction.  Mobile & Marine Systems Ltd. was approached by GAIA Barbados Inc., the management company for the airport, to recommend an effective solution to solve the communication problems for the airline and service companies operating at the airport.

After looking at various options Mobile & Marine Systems Ltd installed a Tait MPT 1327 cell close to the airport.  This gives 100% coverage of the entire complex using Tait T5000 handheld radios.   The system operates in the 450 MHz band and in-building penetration is very good. There are no dead spots.  This cell uses the T800II modules with two traffic channels in addition to the control channel.  We expect to expand the traffic channels as more users come on.

Each airline was set up on a separate fleet and their radios are programmed for group calls.  Group calls are used as the staff was constantly on the move and the radios change hands several times a day.  Making radio unit to radio unit calls was deemed not practical as staff are assigned to fixed locations and not the radios. Some Tait ORCA 5035 radios are used more than 18 hours each day and are supplied with 2 batteries.

Where the customer requires a base station a Tait T2040 or TM8200 and matching power supply is used. The transmit power is set to low power.  A “rubber duck” antenna connected directly to the BNC connector is used instead of an external antenna. This resulted in a significant cost saving. It also made the base very easy to be relocated when the contractors gave the clients 24 hours to move to a new location as their present site was being demolished.

Inter fleet or inter group calls can be easily made. The inter-fleet call feature enables the staff of one airline to contact another airline, when dealing with in-transit passengers, the baggage handlers or security without leaving their station.  The alphanumeric display on the Tait 5035 radio makes selecting the fleet or group to be called very easy.

The hand set feature is very useful when information is being passed that the passengers do not need to know.  It is also useful on the ramp when the radio is used near to a high-pitched aircraft engine.

This Tait Trunked system has proved to be very popular with the users and management at the Grantley Adams International Airport. It has improved the efficiency of the operations.  The fast connection times of the Tait equipment made the change over from a simplex system less of a problem for users accustomed to instant communication.  The increase in range and much clearer reception were clear advantages.  The Tait ORCA series is a very rugged radio and can stand up to heavy use.  Radios can be quickly reprogrammed to other groups to meet changing requirements.

Mobile & Marine Systems Ltd. has found that in the shrinking world of radio communications, the Tait MPT1327 trunk system is still a viable and cost effective solution for communication.

Lord Nelson, Bridgetown, Barbados – erected in 1813, 27 years before London’s Lord Nelson column. Sculpted from bronze by Sir Richard Westmacott, it is considered to be an accurate likeness of the British Admiral.

The Barbados Coast Guard – is the maritime element of the Barbados Defence Force, with responsibility for patrolling Barbados’ territorial waters.  Mobile & Marine Systems Ltd. were asked by the Barbados Coast Guard to design a system to improve their Marine VHF communications range and coverage.

With the coverage of the previous system was limited to approximately 45Km to the west of Barbados which was due to the location of Fort Willoughby, the Coast Guard headquarters in Bridgetown, being located in the south west of Barbados.  There was little coverage to the North, East or South of the island.

Using a combination of  Tait T800II and Tait TM8000 equipment Mobile & Marine Systems Ltd. has been able to provide a cost effective solution to enhance the communication systems of the Barbados Coast Guard.  The radio coverage has now been extended from approximately 45Km to the west of Barbados to a range of approximately 80Km in all directions around Barbados.  In addition to the Marine channels other frequencies in the 150-174MHz band have been provided for secure communications, so enhancing the effectiveness of the Barbados Coast Guard in patrolling Barbados’ territorial waters.

The Tait T800II was a logical choice for this system. These modules can be programmed to operate on several channels which can be selected by the Tait T803 remote control unit.

Using the traditional 4-wire leased lines from Fort Willoughby, the Coast Guard headquarters, to the repeater site was not an option, simply as there were no land lines in its vicinity.   Installing a full duplex radio link we estimated would have increased the cost by five times!

We used two of the very versatile Tait TM8000 series radios to link the base to a remote repeater site.  These radios provide a link for both the channel select tones as well as providing a voice link to ships around Barbados.

At the Coast Guard HQ at Fort Willoughby we used a UHF Tait T8250. Here we interfaced this to a Midian Electronics TRE2 remote tone encoder.  The Midian TRE2 is a simple unit that can send (or generate) the channel select tones to change the channel of the Tait T800II at the repeater site.  The output from the Midian TRE2 is connected to the Tait TM8250 via the Auxiliary Connector on the rear of the radio.

To Select a Marine Channel the appropriate key on the Midian TRE2 is selected and the programmable function key “F4” on the Tait TM8250 is pressed.  This sends the channel select tone to the Repeater site.  Here it is received by a Tait T8110.  A  Tait TMAA01-01 Line Interface Board in the option space of the TM8110 provides a 4 wire interface to pass the channel select tones and voice communication to the Tait T803 channel selector.

The Tait T803 selects the channel of the T800II via the channel select lines.  We have also connected these lines to the external BCD Channel Select lines of the TM8115.  This causes the radio to switch to a channel which corresponds to the selected marine channel.

We programmed each channel of the TM8110 with a different Transmit SELCALL number. The SELCALL parameters have been set to send the SELCALL on the leading edge of the transmission.

This SELCALL is received by the TM8250 at the Coast Guard control room.  Using the address book we linked this received SELCALL to enable the TM8250 to display Marine 06, Marine 12 or which ever channel was selected.  This enables the operator to confirm that the required channel was selected.

The radio coverage now extends to a range of approximately 80Km in all directions around Barbados.  In addition to the Marine channels other frequencies in the 150-174MHz band are used to provide secure communication.

Another VHF TM8200 installed on the Coast Guard ship HMBS Trident gives access to Marine Channels as well as other channels for secure communication.   The built in voice inversion scrambler further enhances the level of security for their operations.

Due to the versatility of the Tait T800II and the Tait TM8000 equipment Mobile & Marine Systems Ltd. has been able to provide a cost effective solution to enhance the communication systems of the Barbados Coast Guard, extending marine radio coverage from just 45Km west of Barbados, to approximately 80Km in all directions around Barbados.  In addition to the Marine channels other frequencies in the 150-174MHz band have also been provided for secure communications, so enhancing the effectiveness of the Barbados Coast Guard in patrolling Barbados’ territorial waters.

Chickmont Foods

Zetron alarm panels and Tait radio solutions allow Chickmont Foods to monitor key processes for their state-of-the-art chicken and hatchery processing facilities.

ChickmontFoodsChickmontFoodsHatcheryChickmont Foods based in Barbaodos West Indies is the leading integrated poultry business in the Southern Caribbean. Chickmont Foods not only represents a number of highly visible brands, including Montrose Farm Fresh, Montrose Premium, Super Chick and Tropical Eggs, but also operates and manages a hatchery, broiler farms, a layer farm and its own retail outlets.  Chickmont Foods state-of-the-art processing facilities are specifically designed to handle multi-tasking operations and use integrated solutions from Tait Radios and Zetron alarm panels to monitor key processes.

Chickmont Foods is the largest supplier of fresh chicken in Barbados, with an annual turnover over of over 3.5 million birds.  Chickmont holds the distinction of being the only ISO 9001 and HACCP certified processing plant in Barbados. (HACCP -pronounced hass-ip – is a world recognised standard, which stands for Hazard Analysis and Critical Control Points. In the US, the Food and Drug Administration and the United States Department of Agriculture have made HACCP a standard that many food companies must follow.)

The fresh chicken produced by Chickmont Foods is free from all hormones and preservatives. Barbadians like their chicken fresh and free from impurities.   Barbadians consume about 25 kg of chicken per person annually. This is understood to be one of the highest per capital consumption figures in the world!

Chickmont Foods delivers day old chicks from their Hatchery, at Lower Estate, to independent farmers across the island.  When they are 6 weeks old they are transported to the processing plant at Balls.  Here they are slaughtered and packaged ready for sale to supermarkets and restaurants across the island.

Mobile & Marine Systems keeps the staff of Chickmont foods in constant contact using a mixture of Tait T2015 mobiles in the refrigerated trucks and handhelds carried by the staff.  These communicate via 3 linked Tait T800II repeaters to provide seamless island wide coverage.

The Lower Estate hatchery is unmanned out side of normal working hours.  The management of Chickmont needed a way to monitor these alarms at both the hatchery and the Balls processing Plant.

Mobile and Maine Systems installed a Zetron M1550 Alarm processing panel at each site.

At the Hatchery this monitors a number of critical functions such as the AC mains, water pressure, cooling fans and incubator temperatures.

At the processing Plant critical functions such AC mains, water pressure, temperature of the various freezers, chillers and boilers are all monitored.

The Zetron M1550 Alarm processing panel reports any alarms via telephone and radio.  A compressive call list will call different people depending on the nature of the alarm.

When you see Banks proclaimed on the side of a rum shop or at the beach you know a delicious cold Banks beer awaits you, delivered via a Tait Radio connected delivery truck supplied by Mobile & Marine Systems – Barbados.

Banks is the award winning beer of choice in Barbados, West Indies.  This is consumed in large quantities by locals and visitors alike.

Mobile and Marine Systems Ltd were asked to supply a radio communications system the ensured the smooth delivery of the product to over 2,000 hotels, bars, night clubs, supermarkets and small shops across the island.

Banks Breweries delivery drivers are their ambassadors in maintaining the brewery’s market share. More that 50 trucks are used to make the deliveries and it was necessary to maintain radio contact with all the trucks to make sure that every customer had a good supply of Banks.

Some of the routes covered are in  areas where repeater coverage is very poor due to the hills and valleys.  Using one repeater would not give the coverage required.

Mobile & Marine Systems Ltd installed a 3 site UHF Tait T800II repeater system.  The three sites are linked together to provide seamless coverage across the island.

Each Tait T2015II is programmed with the three channels. The driver switches to the channel which gives the best coverage on his given route.  Due to the location of the repeaters and the coverage of each repeater drivers seldom have to change channels during a day.  Each of the three channels can also be accessed from the delivery bond.

In addition Mobile  & Marine Systems installed SELCALL in each vehicle. The base was a Tait T2020, and we made full use of the SELCALL features.

What SELCALL means is individual delivery trucks can be called from the Base. The called device will ring notifying the driver that he is required.  This is particularly useful where the driver is constantly out of the cab. When he returns a ring tone, or a flashing light, will indicate that the base was trying to make contact.  The device can also be used to call the base.  The display on the base will indicate the number of the device calling.

The Tait radio solution that Banks’ use has substantially improved the efficiency and effectiveness of getting Banks beer to where it’s needed, when it’s needed and has helped Banks to increase their bottom line profitability through improved logistics management.

Trailer based radio repeater station

Using a trailer based repeater station to provide radio communication for special events and as a backup in times of national emergency.

Mobile & Marine Systems trailer based mobile repeater for use at special events and in times of national emergency.
Mobile & Marine Systems trailer based mobile repeater for use at special events and in times of national emergency.

Crop Over is the premier cultural event in Barbados. It has it origins in the celebrations held at the end of the Sugar cane harvesting Season each year. The carts carrying the last loads of canes to the windmills were decorated with flowers, and the workers took some time off to celebrate another successful sugar crop, and sample some of the by-product of sugar cane – Rum.

The CropOver festival has evolved to its present state where every section in the island takes part.  It showcases the Music, Art, Food and Dance of Barbados over a 3 week period in July each year.

One of the main events of the Crop-Over festival is an open-air concert on the East Coast Road in a natural amphitheatre over looking the Atlantic Ocean.  The site is excellent for the show but the logistics of setting it up and organising it are a nightmare for the Crop Over organisers, The National Cultural Foundation (NCF).

No electricity, water or telephones are available at the site. Due to the nature of the terrain and the amphitheatre, cell phones and all of the repeater systems on the island give very limited coverage. This is not a part of the island where people want to be contacted!

In 2000 Mobile & Marine Systems were asked to set up a system that would give island wide coverage as well as coverage to the East Coast Road for the week before and after the show. This would be used to control the set-up and take down of the stage and equipment.

We decided on using the Tait T800II Repeater the NCF had been using for years, and make a Mobile Repeater that could be quickly transported to the site.

We used a trailer with a tilt over telescoping 7-meter mast. We put a battery box to hold two 100Ahr Batteries and a 19-inch Rack to mount the equipment.  The System is powered by a Solar Panel.

The repeater is a Tait T800II 25-Watt VHF System.  A Tait T2015, with a T2000-80 Line Interface board, providing the link back to the main Highland Repeater site.

The radios are programmed with two channels. Channel #1 is set for the Highland Repeater Site and Channel #2 is for the mobile East Coast Road Repeater.

The User selects the channel according to his location. With the Tait Orca T5000 radios voting can be used so that the user is not aware of which repeater is selected. SELCALL can be used between units on either repeater. In addition we set up base stations at the entry gates powered by car batteries, as there is no AC power available.

In the days before the show the system is used to co-ordinate between the NCF Office and the stage management crew.  Before Mobile & Marine Systems supplied this Tait T800II system there was no communication between the site and the head office.

During the show it is used by the Gate control, Transport co-ordinator, Security and the Emergency services. Every one is on the same system and is kept abreast of any problems that arise; enabling them to be dealt with in an efficient manner.

Due to the limited parking on site all private vehicles are parked about 5km away and buses are used to ferry the patrons in. This makes communication essential at the end when 20,000 people wish to leave as soon as the last performer has left the stage!

This is a long day for the organisers.  It starts around 5am and will not end until the last reveller has left, around 11pm.

This Mobile Tait Repeater system has proved very useful in setting up short-term communication to other customers who may wish to have coverage for a particular area. We can link it back to any other repeater system by simply reprogramming the T2015.

For Mobile & Marine Systems it has also enhanced our short-term lease revenue as we can offer a quick and efficient service to anywhere in the island at short notice.

If Barbados was ever to have a major hurricane or national emergency this trailer based mobile repeater solution also features in the island’s disaster management / emergency relief plan.  It would be used to set up a mobile emergency communications network similar to the one that Mobile & Marine Systems set up in Grenada following Hurricane Ivan for the Grenada Police Force.

Green Powered Mobile Radio Repeaters

Mobile & Marine Systems Ltd is a green company and has been using renewable energy to power its repeater stations since 1981.

MMS_WindAndSolarCellPower_HighlandWith the recent conflicts in areas that produce the majority of the worlds oil, and the effects that the emission of Carbon Dioxide has on global warming there is a pressing need for a source of cheap and clean energy.

Mobile & Marine Systems Ltd started generating electricity using Photovoltaic and wind in 1981.   These were used as a necessity as our first repeater site at Highland was not close to the electrical grid.  It started with just 2 panels producing 90 Watts and today we have expanded this to produce over 900 watts at peak.

When we erected our Grand View repeater site we installed solar panels as a supplement to the mains electricity.   This investment has resulted in huge benefits since it was commissioned 25 years ago. During a sunny day the panels produce 90% of the power required to operate the site, even with a trunk system running. On cloudy days and at night the power is drawn from the grid.

We also have 2 other sites, where mains power is available but have opted to power these solely by Photovoltaic power.

Our Portable repeater trailer is also powered by solar panels which allow us to set–up without having to look for a source of mains electricity.

Long before it became fashionable for companies to look at the possibilities of cutting their energy costs Mobile & Marine Systems Ltd have been designing and installing highly effective solar powered and wind powered systems to support our business by making saving on our energy costs.

Grenada, a volcanic island of 90,000 people that is a major producer of nutmeg, cloves and other spices, was was struck by Hurricane Ivan on Tuesday 7th September 2004. It was one of the worst hurricanes to hit the West Indies in 10 years.

In the aftermath of Hurricane Ivan, Mobile & Marine Systems received an urgent call to help the Grenada Police Force set up a mobile emergency radio communication network and immediately mobilised its emergency response team.  The Grenada Police Force had lost all their radio communication systems in the Hurricane.

The call came from the Barbados Defence Force operating in Grenada as part of the Eastern Caribbean Regional Security System (RSS).  This Regional Security Force had been seeking to help bring the Grenada internal security situation under control where post Hurricane Ivan a dusk-to-dawn curfew was put into effect, however, lack of effective radio communications was hampering progress.

Within 24 hours of receiving the call, Mobile & Marine Systems, had in place in Grenada a working solution using Tait Portable Repeaters, Tait Mobile Radio Base Stations and Tait Orca Portable Handheld Radios, which provided the emergency backbone for island wide communications for the Grenada Police Force, helping bring order to the country in the aftermath of this disaster.

On Tuesday 7th September 2004 when Hurricane Ivan slammed into Grenada it caused structural damage to approximately 90 percent of the country’s homes and to nearly every major building in the Grenadian capital of Saint George’s, cut power lines and took out all the island’s communication links.

Ivan was a category 3 hurricane on the Saffir-Simpson scale when it passed by Barbados, St. Lucia, St. Vincent and the Grenadines, and Trinidad and Tobago on Tuesday.   Ivan then strengthened into a category 4 hurricane as it hit Grenada on Tuesday evening, bringing sustained winds of 220 km/h.

Hurricane Ivan destroyed the island’s emergency operations centre, the Prime Minister Dr. Keith Mitchell’s residence, the prison, many schools, and damaged the main hospital.

The International Federation of the Red Cross stated at the time that at least 17 people died, approximately 60,000 people were made homeless with 5,000 to 8,000 persons in 47 emergency shelters, 30 of which are official shelters and 17 of which were established on an ad-hoc basis.  Also among the damaged buildings was the Grenada Red Cross Society headquarters.

Prime Minister Dr. Keith Mitchell told BBC Radio: “We have got a tremendous hit that we never expected – you are talking hundreds of millions of dollars of damage. We have declared the country a national disaster, contacted our international friends and indicated that”…  “I am pretty sure we have taken a tremendous hit in the nutmeg industry, which is a key barometer of our economic development”, he added.


Here is a personal account of the Tait emergency radio solutions installed in Grenada post Hurricane Ivan, taken from a situation report filed by one of Mobile & Marine Systems on-the-ground team:

On Tuesday 7th September 2004 Hurricane Ivan hit Grenada and for nearly 12 hours the island was subjected to storm force winds in excess of 220 km/h.  When it was all over the following morning the “Spice Island” was devastated.

Mobile & Marine Systems received a call from the Barbados Defence Force around 9pm on the Wednesday 8th of September requesting that we set up an emergency communications system, using equipment from the Barbados Defence Force and Mobile & Marine Systems stock.

After discussing the requirements we decided to use a Tait T800II Portable Repeater and a mixture of Tait T2015 Mobile Radio Base Stations and Tait Orca T3000 / T5000 portable handheld radios.  The radios were programmed with the repeater and a number of simplex channels and Marine VHF channels.

By next morning we had the equipment ready to go, however, getting transport into Grenada proved to be a problem.  Point Salines International Airport was officially closed to traffic as the control tower had sustained damage.

I finally hitched a ride on a US Coastguard flight around 2pm on Thursday 9th of September 2004 ( two days after the hurricane had hit Grenada).  The plane was loaded to maximum with equipment and 5 passengers who were part of an international assessment team.

On the 40 minute flight down to Grenada there was the usual talk with each of us telling what our area of interest was.  However, as the plane banked over the Southern part of Grenada all conversation ceased as the size of the damage to the island became apparent.

Once on the ground the plane was quickly unloaded and our communication equipment was stacked on the tarmac while the plane turned around.  It was very apparent I was now on my own.

I managed to find someone from the Grenada Police Force and he arranged for an open truck to carry me to the Fort George Police Headquarters.  The drive from the Airport was very slow due to fallen trees, poles and debris from roofs.  The pictures do not tell the story of the destruction.  No building seems to have escaped some form of damage.

After about 90 minutes we arrived at Fort George Police Headquarters.  A 5 mile journey that normally takes 10 to 15 minutes.  Fort George is the site of a 200 year old fort.  It is on a 200 meter high hill overlooking the capital, St. George’s.  The Police station which has a concrete roof had generally remained intact albeit most of its windows were missing.  On arrival I found that the Grenada Police Force had lost all their communication systems in the Hurricane.

After a short meeting with the Commissioner of Police I erected a temporary antenna on a hand rail and ran 20 meters of coaxial cable to the Tait T800II Portable Repeater.  Given the emergency conditions, the Tait T800II Portable Repeater was left in the open sealed in a plastic bag to protect it from the elements.  I switched on the internal battery and we had a working repeater system, all in about 45 minutes of arriving at Fort George Police station!  This Tait T800II Portable Repeater worked using its internal battery until the next day when we were able to secure an AC power connection from a nearby standby generator.

Having set up the Tait T800II Portable Repeater, Mobile Handhelds Radios were quickly passed out to patrols on-the-ground.

I then returned to Point Salines where I set up a Tait T2015 Mobile Radio Base Station this time using a car battery as the power source.

The next day, Friday 10th of September 204, I set up another Tait T2015 Mobile Radio Base Station at Point Salines International Airport, together with a HF transceiver to communicate outside the island.  The latter consisted of an Icom  IC-707 and an  AT-130E Automatic Tuner which was connected to a long wire antenna stretched from a flag pole to the Airport building.  I also returned to Fort George Police Headquarters where I moved the Tait T800II Portable Repeater into a secure room and repositioned the antenna to the highest point at Fort George.

In emergency situations like the aftermath of Hurricane Ivan in Grenada the Tait T800II Portable Repeater is a logical choice.  It is light.  It is robust.  It is water proof.  And, the internal batteries make it a self contained unit.  All that is needed is an antenna and a length of coaxial cable to connect it to the N-Type connector on the top of the unit.  Another advantage is that it can be used as a base station as well, which under emergency conditions free up scarce portable radios for use in the field.

Even though this Tait equipment was handled very roughly on its journey from Barbados to Grenada and on the trip from the airport where it travelled in the back of an open truck, it has performed with out a hitch.

The Tait T2015 Mobile Radio Base Stations and Tait Orca T3000 / T5000 Portable Handheld Radios proved to be very reliable under such trying situation.  The power save feature on the Tait Orca T3000 / T5000 Portable Handheld Radios give the batteries a longer cycle between recharging.  What’s more the Tait Chargers can be powered from 12v DC car batteries!

The Hurricane Ivan disaster in Grenada has proved, as if we did not already know it, that despite all of the hype about modern technology nothing can replace a basic repeater system.  When I arrived in Grenada there was little operational communications.  Two of the cell phones suppliers were totally off the air and the third had very limited coverage.  The few cell sites that were still standing were quickly overloaded and getting through was very sporadic.  A few satellite phones were brought in, but as soon as their batteries went dead that was the end.

The Barbados Defence Force and Mobile & Marine Systems initially operated the Tait T2015 Mobile Radio Base Stations using car batteries until a generator could be obtained.  Likewise the chargers for the Tait T3000 / T5000 Portable Handheld radios were also powered from a number of salvaged car batteries which were readily available from vehicles wrecked by falling trees.  The internal battery in the Tait T800II Repeater operated for over 24 hours and is ideal for emergency situations.

Postscript: The Eastern Caribbean Regional Security System (RSS) Force in Grenada departed on the 15th of December 2004.  The operation was very successful in  maintaining law and order, delivering and controlling relief supplies and repairing or rebuilding critically damaged infrastructure.  This has been a good example of where the people of the Eastern Caribbean came together to help a neighbour in a time of dire crisis.

The Tait repeater played a very important part in this operation and proved to be very reliable over the time it was in operation.  The Tait T800 portable Repeater system kept the RSS control base at Point Salines in contact with units across the Southern area of Grenada.

I visited Grenada again during the first week in December 2004 and was pleased to see the rate of reconstruction that had taken place.  Electricity and telephones were back up as were the cell phones.  The tourist industry still needs a lot of rebuilding but most hoteliers are taking this chance to improve their operation. When they are fully reopened in the middle of 2005,  Grenada will a very modern hotel plant which will rival any in the Caribbean.

Click here to see how Mobile & Marine Systems has set up a trailer based mobile repeater for the Barbados National Cultural Foundation, which is also held in reserve as part of the island’s Disaster Management / Emergency Relief plan.  The base system comprises of a trailer with a tilt over telescoping 7-meter mast, a battery box, a 19 inch rack containing a Tait T800II repeater, a Tait T2015 with a Tait T2000-80 line interface board and a solar array panel.
