WRMI TECHNICAL SUMMARY
www.wrmi.net
Location: The property is in an agricultural part of rural Okeechobee County, about two and a half hours north of Miami and about 20 miles north of Lake Okeechobee. (North Latitude 27 degrees, 27 minutes, 30 seconds. West Longitude 80 degrees, 56 minutes, 00 seconds.) The property is around 660 acres, just a little more than a standard section. In round numbers, it is about one square mile..
Climate: Semi-tropical with a high incidence of thunderstorms during the summer months.
Terrain: Relatively flat pastureland, swampy in places.
Mains Power: 60 Hz, 22,800 volts stepped down to 480 volts
Transmitters:
Twelve 100,000 watt and one 50,000 watt. All are high-level plate modulated (some include supplementary screen and control grid modulation). Some are entirely air-cooled; some also use water cooling and vapor-phase cooling. The transmitter building is 16,000 square feet. The 13 transmitters consist of two 100 kW Continental 418-Ds, and eight composite-construction 100 kW transmitters based on the 418-D but built by WYFR. One of the transmitters has been retrofitted with a solid state modulator and could be converted to DRM digital operation. There are three older Gates/Harris transmitters (1 x 50-kilowatt and 2 x 100-kilowatt).
All of the 100-kw transmitters can also be operated at 50 kilowatts, and one of them is able to operate at a continuously-variable power level up to 100 kilowatts.
*From my experience, the day Tx is usually highest power (100kw) and night Tx is only 50kw.
