The Marshall Islands are a small group of islands that form a part of Micronesia in the central Pacific, about half way between Hawaii and Australia. The Marshalls are made up of 34 coral atolls with a total area of just 70 square miles and a total coastline of just 75 miles.

These islands run in two parallel chains about 130 miles apart and they extend for 650 miles. The capital island is Majuro and the total population is around 75,000.

The Marshall Islands were first populated by Micronesians who migrated into the area approximately 3,000 years ago. The first Europeans to sight the islands were from Spain, the islands were named by the British, and Germany bought them from Spain in 1885.

The Japanese were granted a mandate over the islands from the League of Nations in 1920, and the Americans were granted a mandate from the United Nations in 1946. The Marshall Islands gained independence in 1986.

Three island atolls in the Marshalls have achieved world wide fame. Kwajelein & Eniwetok were the location of two fierce battles during the Pacific War, and Bikini & Eniwetok were the locations for the American atomic tests in the Pacific a few years later.

Radiowise, the first transmitter in the Marshall Islands was established under the Japanese mandate on the southern island of Jaluit (ja-LOO-it) somewhere around the mid-1920’s. This was a communication station under the callsign JRX.

In 1944, American forces established two stations in the Marshall Islands; WXLG with 1 kW on Kwajelein and WXLE with just 50 watts on Eniwetok. Two years later, radio played another important role during the American atomic tests on Bikini and Eniwetok. The radio transmitters on several ships relayed a live broadcast from a nearby location, giving a running commentary of the events associated with the atomic explosions.

The mediumwave station WSZO began with just 200 watts on 1500 kHz somewhere around the year 1960. This station was established by the local government and it was supplementary to the two AFRS stations on the air in this island group in the central Pacific.

In 1980, on March 4 to be exact, a new 1 kW transmitter at station WSZO made its first appearance on the shortwave bands. Two channels were in use, 6070 kHz & 4940 kHz, though the tropical band channel gave the widest coverage.

A few months later, the station stated that they were swamped with reception reports from all over the world, though mainly from Australia, New Zealand and North America. The transmitter was a Japanese NEC 10 kW unit and the antenna was beamed north west.

Two years after its inauguration, the shortwave service came to an abrupt end when the antenna balun (BAL-un) failed. This service for the outer islands was never revived and gone was the possibility for distant listeners to hear this exotic radio station in the central Pacific.

However, there is good news. Several recent news reports state that the Kentucky shortwave station WJIE, with its offices in Louisville and transmitters at Upton, indicate that they have bought the three shortwave transmitters from FEBA Seychelles. They are apparently planning to install one in Liberia, another in the United States, and the third in the Marshall Islands.

The government radio station in the Marshall Islands began its on air service under the callsign WSZO and this was changed to V7AD after independence. What will be the callsign for this new Gospel shortwave station in the Marshall Islands?
