Carriacou, along with Petit Martinique, are separate islands which are part of Grenada, the main island. Carriacou has approximately 8560 square acres and is inhabited by nearly 7000 people with three distinct European influences. The French influence is found in the South, the Scottish in the Northeast, and the English on the Western side. The two main sources of income are boating (fishing and trading) and farming. The language is English with a flavour of the area of influence. We are using a 100% solid state 5Kw Nautel AM transmitter. Our audio processor is a CRL system with the NRSC pre-emphasis. The antenna is a quarter-wave, series-fed, monopole 55 meters in height with an above-ground tuned radial ground system that uses only 4 wires 55 meters in length perpendicular to each other and raised 5 meters above the ground for our frequency of 1400Khz. The computer models show that it is as good or slightly better than the conventional ground system with 120 radials buried in a circle around the tower. Our tests have proved this also. The beauty of this system is its ease of installation, maintenance and low cost. We use a standard ATU (antenna tuning unit) for matching the tower to the transmitter. We went on the air on 1 December 1991
Our primary coverage (0.5mv/m) area includes a 300km radius. We've received signal reports from all the Islands in our coverage area, South America, and Europe. Our FM transmitters are 250 watt Crowns, which are on 24 hours daily (94.5, 92.3MHz), and cover primarily Grenada and Carriacou & the Grenadines. Our programmes are primarily Bible preaching and teaching in nature, however, we have science programmes, drama programmes, programmeson the family and home, daily classical music programmes, weather, and world news from the BBC. We were the only radio station in Grenada to remain on the air during Hurricane Ivan on September 7, 2004. Pictured below (left) is our AM Nautel 5kw solid state transmitter with the control rack on the left. It was installed new in October of 1991 and has been in operation ever since. It operated nearly flawlessly for ten years before we had our first real trouble. The capacitors in the combiner failed which caused damage to the other components in the cabinet. The next picutre (middle) is our Audio/FM rack in the Tech-Shop. It houses our AM monitor (GM car radio) with a Radio Shack amp for 70 volt distribution. Below the radio and amp is the first stage of our CRL audio processor. Below the CRL is an old "DAP" (discriminate audio processor) which is there for backup. Below the DAP is the first stage of our Crown 250w FM repeater system. It operates on 92.3Mhz as a link to our 94.5Mhz translator (Crown 250w) in Grand E'tang, Grenada. The picture on the right is a shot of our SWR four-bay, circularly polarized FM antenna. We use the same antennas in Grenada for transmitting and a custom receive antenna (see picture below). For you old-timers, that is an old General Radio AM Modulation monitor in the rack on the left side of the AM transmitter which still "sort-of" works.
This is the FM site in Grand E'tang, Grenada
