Galcom International’s ministry focuses on “low-powered” broadcasting only. Low-powered radio broadcasting is typically considered to be any station with a transmitter of 2,000 watts of power or less. Other technical missions such as Trans World Radio (TWR) and HCJB can help with high-powered broadcasting needs.
The use of low-powered broadcasting is spreading rapidly worldwide in the following ways:
New micro technology has improved quality and reduced the size of components. An entire radio station can fit into one suitcase and studio equipment in another. Installation takes only a few days. Also, in very remote areas a low-powered station can run completely off of solar or wind-generated power.
Politically, it is easier in many countries to receive approval for a low powered or community license than a large commercial station license.
The cost of a low-powered FM-radio station is relatively low. Transmitter prices for 10 watts to 2,000 watts typically range from $1,500 up to $20,000 US dollars. The cost for a basic semi-professional radio studio is approximately $4,000. However, a complete basic station can be installed for as little as $4,800 for transmitter, antenna and studio.
Typically, a low-powered radio-station broadcast will reach a 20 to 30-mile radius depending on terrain, the wattage of the transmitter, and the height of the transmitting tower. Distribution of solar-powered, fix-tuned radios can blanket an area surrounding the radio station, reaching thousands of people up to twenty-four hours a day in their own language.
